| Methods' Details |
containsPoint
| boolean |
| containsPoint( |
[in] ::com::sun::star::awt::Point |
aPoint ); |
- Description
- Tests whether the specified point lies within this object's bounds.
The test point's coordinates are defined relative to the
coordinate system of the object. That means that when the object is
an opaque rectangle then both the points (0,0) and (with-1,height-1)
would yield a true value.
- Parameter point
- Coordinates of the point to test. The origin of the coordinate
system is the upper left corner of the object's bounding box as
returned by the getBounds. The scale of the
coordinate system is identical to that of the screen coordiante
system.
- Returns
- Returns true if the point lies within or on the object's bounding
box and false otherwise.
|
|
getAccessibleAtPoint
- Description
- Returns the Accessible child that is rendered under the given point.
The test point's coordinates are defined relative to the
coordinate system of the object. That means that when the object is
an opaque rectangle then both the points (0,0) and (with-1,height-1)
would yield a true value.
- Parameter aPoint
- Coordinates of the test point for which to find the Accessible
child. The origin of the coordinate system is the upper left
corner of the object's bounding box as returned by the
getBounds. The scale of the coordinate
system is identical to that of the screen coordiante system.
- Returns
- If there is one child which is rendered so that its bounding box
contains the test point then a reference to that object is
returned. If there is more than one child which satisfies that
condition then a reference to that one is returned that is
painted on top of the others. If no there is no child which is
rendered at the test point an empty reference is returned.
|
|
getBounds
- Description
- Returns the bounding box of this object.
The returned bounding box has the form of a rectangle. Its
coordinates are relative to the object's parent coordinate system.
Note that the two methods getLocation and
getSize return the same information. With method
getLocationOnScreen you can get the bound box
position in screen coordinates.
- Returns
- The coordinates of the returned rectangle are relative to this
object's parent or relative to the screen on which this object
is rendered if it has no parent. If the object is not on any
screen the returnred rectangle is empty and located at position
(0,0).
|
|
getLocation
| ::com::sun::star::awt::Point |
| getLocation(); |
- Description
- Returns the location of the upper left corner of the object's
bounding box relative to the parent.
The coordinates of the bounding box are given relative to the
parent's coordinate system.
- Returns
- The coordinates of the returned position are relative to this
object's parent or relative to the screen on which this object
is rendered if it has no parent. If the object is not on any
screen the returnred position is (0,0).
|
|
getLocationOnScreen
| ::com::sun::star::awt::Point |
| getLocationOnScreen(); |
- Description
- Returns the location of the upper left corner of the object's
bounding box in screen coordinates.
This method returns the same point as does the method
getLocation. The difference is that the
coordinates are absolute screen coordinates of the screen to which
the object is rendered instead of being relative to the object's
parent.
- Returns
- The coordinates of the returned position are relative to the
screen on which this object is rendered. If the object is not
on any screen the returnred position is (0,0).
|
|
getSize
| ::com::sun::star::awt::Size |
| getSize(); |
- Description
- Returns the size of this object's bounding box.
- Returns
- The returned size is the size of this object or empty if it is
not rendered on any screen.
|
|
grabFocus
| [oneway] void |
| grabFocus(); |
- Description
- Grabs the focus to this object.
If this object can not accept the focus,
i.e. isFocusTraversable returns false for this
object then nothing happens. Otherwise the object will attempt to
take the focus. Nothing happens if that fails, otherwise the object
has the focus. This method is called requestFocus in
the Java Accessibility API 1.4.
|
|
getForeground
| ::com::sun::star::util::Color |
| getForeground(); |
- Description
- Returns the foreground color of this object.
- Returns

that is not supported, the default foreground color.
|
|
getBackground
| ::com::sun::star::util::Color |
| getBackground(); |
- Description
- Returns the background color of this object.
- Returns
- The returned color is the background color of this object or, if
that is not supported, the default background color.

It’s used to manage connections persistance and reuse for HTTP clients, and it’s a key component of Node HTTP networking. More in the `http.Agent` class description later on. --- ### Methods --- #### `http.createServer()` Return a new instance of the `http.Server` class. Usage: ```js const server = http.createServer((req, res) => { //handle every single request with this callback }) ``` --- #### `http.request()` Makes an HTTP request to a server, creating an instance of the http.ClientRequest class. --- #### `http.get()` Similar to http.request(), but automatically sets the HTTP method to GET, and calls req.end() automatically. --- ### Classes The HTTP module provides 5 classes: - `http.Agent` - `http.ClientRequest` - `http.Server` - `http.ServerResponse` - `http.IncomingMessage` --- #### `http.Agent` Node creates a global instance of the `http.Agent` class to manage connections persistance and reuse for HTTP clients, a key component of Node HTTP networking. This object makes sure that every request made to a server is queued and a single socket is reused. It also maintains a pool of sockets. This is key for performance reasons. --- #### `http.ClientRequest` An `http.ClientRequest` object is created when `http.request()` or `http.get()` is called. When a response is received, the response event is called with the response, with an `http.IncomingMessage` instance as argument. The returned data of a `response` can be read in 2 ways: 1. you can call the `response.read()` method in the `response` event handler 2. you can setup an event listener for the `data` event, so you can listen for the data streamed into. --- #### `http.Server` This class is commonly instantiated and returned when creating a new server using `http.createServer()`. Once you have a server object, you have access to its methods: - `close()` stops the server from accepting new connections - `listen()` starts the HTTP server and listens for connections --- #### `http.ServerResponse` Created by an `http.Server` and passed as the second parameter to the `request` event it fires. Commonly known and used in code as `res`: ```js const server = http.createServer((req, res) => { //res is an http.ServerResponse object }) ``` -- #### `http.ServerResponse` The method you’ll always call in the handler is `end()`, which closes the response, the message is complete and the server can send it to the client. It must be called on each response. These methods are used to interact with HTTP headers: - `getHeaderNames()` get the list of the names of the HTTP headers already set - `getHeaders()` get a copy of the HTTP headers already set - `setHeader('headername', value)` sets an HTTP header value - `getHeader('headername')` gets an HTTP header already set - `removeHeader('headername')` removes an HTTP header already set - `hasHeader('headername')` return true if the response has that header set - `headersSent()` return true if the headers have already been sent to the client --- #### `http.ServerResponse` After processing the headers you can send them to the client by calling `response.writeHead()`, which accepts the statusCode as the first parameter, the optional status message, and the headers object. To send data to the client in the response body, you use `write()`. It will send buffered data to the HTTP response stream. If the headers were not sent yet using `response.writeHead()`, it will send the headers first, with the status code and message that’s set in the request, which you can edit by setting the `statusCode` and `statusMessage` properties values: ```js response.statusCode = 500 response.statusMessage = 'Internal Server Error' ``` --- #### `http.IncomingMessage` An `http.IncomingMessage` object is created by: - `http.Server` when listening to the `request` event - `http.ClientRequest` when listening to the `response` event -- It can be used to access the response: - status using its `statusCode` and `statusMessage` methods - headers using its `headers` method or `rawHeaders` - HTTP method using its `method` method - HTTP version using the `httpVersion` method - URL using the `url` method - underlying socket using the `socket` method -- The data is accessed using streams, since `http.IncomingMessage` implements the Readable Stream interface. --- # The End

There is a growing trend of utilizing Visualization-oriented Natural Language Interfaces (V-NLIs) to author charts. However, researchers consistently highlight the lack of high-quality chart and natural language datasets, which impedes the development of more sophisticated and data-driven systems using V-NLIs. In this study, we present a meticulously curated collection of human-generated 1,981 Vega-Lite specifications, derived from real-world data, and use Large Language Models (LLMs) for generating natural language queries for chart generation tasks. Unlike previous datasets that relied on relatively simple and homogeneous templates, our Vega-Lite dataset contains more complex and diverse (i.e., varying interactions, composite views, and different chart types). Using this dataset, we demonstrate generating natural language queries for chart generation, and how the results can be different when different input types are used (e.g., Vega-Lite, Image, both Vega-Lite and Image). |

Zadu: A python library for evaluating the reliability of dimensionality reduction embeddings
Hyeon Jeon, Aeri Cho, Jinhwa Jang, Soohyun Lee, Jake Hyun, Hyung-Kwon Ko, Jaemin Jo, Jinwook Seo VIS 2023 short
paper /
code
Dimensionality reduction (DR) techniques inherently distort the original structure of input high-dimensional data, producing imperfect low-dimensional embeddings. Diverse distortion measures have thus been proposed to evaluate the reliability of DR embeddings. However, implementing and executing distortion measures in practice has so far been time-consuming and tedious. To address this issue, we present ZADU, a Python library that provides distortion measures. ZADU is not only easy to install and execute but also enables comprehensive evaluation of DR embeddings through three key features. First, the library covers a wide range of distortion measures. Second, it automatically optimizes the execution of distortion measures, substantially reducing the running time required to execute multiple measures. Last, the library informs how individual points contribute to the overall distortions, facilitating the detailed analysis of DR embeddings. By simulating a real-world scenario of optimizing DR embeddings, we verify that our optimization scheme substantially reduces the time required to execute distortion measures. Finally, as an application of ZADU, we present another library called ZADUVis that allows users to easily create distortion visualizations that depict the extent to which each region of an embedding suffers from distortions. |

Moderating Customer Inquiries and Responses to Alleviate Stress and Reduce Emotional Dissonance of
Customer Service Representatives
Hyung-Kwon Ko, Kihoon Son, Hyoungwook Jin, Yoonseo Choi, Xiang Anthony Chen CHI 2023 Generative AI and HCI Workshop
paper
Customer service representatives (CSRs) face significant levels of stress as a result of handling disrespectful customer inquiries and the emotional dissonance that arises from concealing their true emotions to provide the best customer experience. To solve this issue, we propose ExGPTer that uses ChatGPT to moderate the tone and manner of a customer inquiry to be more gentle and appropriate, while ensuring that the content remains unchanged. ExGPTer also augments CSRs' responses to answer customer inquiries, so they can conform to established company protocol while effectively conveying the essential information that customers seek. |

Large-scale Text-to-Image Generation Models for Visual Artists' Creative Work
Hyung-Kwon Ko, Gwanmo Park, Hyeon Jeon, Jaemin Jo, Juho Kim, Jinwook Seo IUI 2023
paper /
video /
doi
Large-scale Text-to-image Generation Models (LTGMs) (e.g., DALL-E), self-supervised deep learning models trained on a huge dataset, have demonstrated the capacity for generating high-quality open-domain images from multi-modal input. Although they can even produce anthropomorphized versions of objects and animals, combine irrelevant concepts in reasonable ways, and give variation to any user-provided images, we witnessed such rapid technological advancement left many visual artists disoriented in leveraging LTGMs more actively in their creative works. Our goal in this work is to understand how visual artists would adopt LTGMs to support their creative works. To this end, we conducted an interview study as well as a systematic literature review of 72 system/application papers for a thorough examination. A total of 28 visual artists covering 35 distinct visual art domains acknowledged LTGMs’ versatile roles with high usability to support creative works in automating the creation process (i.e., automation), expanding their ideas (i.e., exploration), and facilitating or arbitrating in communication (i.e., mediation). We conclude by providing four design guidelines that future researchers can refer to in making intelligent user interfaces using LTGMs. |

We-toon: A Communication Support System between Writers and
Artists in Collaborative Webtoon Sketch Revision

doi
We present a communication support system, namely We-toon, that can bridge the webtoon writers and artists during sketch revision (i.e., character design and draft revision). In the highly iterative design process between the webtoon writers and artists, writers often have difficulties in precisely articulating their feedback on sketches owing to their lack of drawing proficiency. This drawback makes the writers rely on textual descriptions and reference images found using search engines, leading to indirect and inefficient communications. Inspired by a formative study, we designed We-toon to help writers revise webtoon sketches and effectively communicate with artists. Through a GAN-based image synthesis and manipulation, We-toon can interactively generate diverse reference images and synthesize them locally on any user-provided image. Our user study with 24 professional webtoon authors demonstrated that We-toon outperforms the traditional methods in terms of communication effectiveness and the writers’ satisfaction level related to the revised image. |

Uniform Manifold Approximation with Two-phase Optimization

paper /

doi
We introduce Uniform Manifold Approximation with Two-phase Optimization (UMATO), a dimensionality reduction (DR) technique that improves UMAP to capture the global structure of high-dimensional data more accurately. In UMATO, optimization is divided into two phases so that the resulting embeddings can depict the global structure reliably while preserving the local structure with sufficient accuracy. As the first phase, hub points are identified and projected to construct a skeletal layout for the global structure. In the second phase, the remaining points are added to the embedding preserving the regional characteristics of local areas. Through quantitative experiments, we found that UMATO (1) outperformed widely used DR techniques in preserving the global structure while (2) producing competitive accuracy in representing the local structure. We also verified that UMATO is preferable in terms of robustness over diverse initialization methods, number of epochs, and subsampling techniques. |

Distortion-Aware Brushing for Interactive Cluster Analysis in Multidimensional Projections
Hyeon Jeon, Michael Aupetit, Soohyun Lee, Hyung-Kwon Ko, Youngtaek Kim, Jinwook Seo Arxiv 2022 (Under review)
paper /
code
Brushing is an everyday interaction in 2D scatterplots, which allows users to select and filter data points within a continuous, enclosed region and conduct further analysis on the points. However, such conventional brushing cannot be directly applied to Multidimensional Projections (MDP), as they hardly escape from False and Missing Neighbors distortions that make the relative positions of the points unreliable. To alleviate this problem, we introduce Distortion-aware brushing, a novel brushing technique for MDP. While users perform brushing, Distortion-aware brushing resolves distortions around currently brushed points by dynamically relocating points in the projection; the points whose data are close to the brushed data in the multidimensional (MD) space go near the corresponding brushed points in the projection, and the opposites move away. Hence, users can overcome distortions and readily extract out clustered data in the MD space using the technique. We demonstrate the effectiveness and applicability of Distortion-aware brushing through usage scenarios with two datasets. Finally, by conducting user studies with 30 participants, we verified that Distortion-aware brushing significantly outperforms previous brushing techniques in precisely separating clusters in the MD space, and works robustly regardless of the types or the amount of distortions in MDP. |

Measuring and explaining the inter-cluster reliability of multidimensional projections

post
We propose Steadiness and Cohesiveness, two novel metrics to measure the inter-cluster reliability of multidimensional projection (MDP), specifically how well the inter-cluster structures are preserved between the original high-dimensional space and the low-dimensional projection space. Measuring inter-cluster reliability is crucial as it directly affects how well inter-cluster tasks (e.g., identifying cluster relationships in the original space from a projected view) can be conducted; however, despite the importance of inter-cluster tasks, we found that previous metrics, such as Trustworthiness and Continuity, fail to measure inter-cluster reliability. Our metrics consider two aspects of the inter-cluster reliability: Steadiness measures the extent to which clusters in the projected space form clusters in the original space, and Cohesiveness measures the opposite. They extract random clusters with arbitrary shapes and positions in one space and evaluate how much the clusters are stretched or dispersed in the other space. Furthermore, our metrics can quantify pointwise distortions, allowing for the visualization of inter-cluster reliability in a projection, which we call a reliability map. Through quantitative experiments, we verify that our metrics precisely capture the distortions that harm inter-cluster reliability while previous metrics have difficulty capturing the distortions. A case study also demonstrates that our metrics and the reliability map 1) support users in selecting the proper projection techniques or hyperparameters and 2) prevent misinterpretation while performing inter-cluster tasks, thus allow an adequate identification of inter-cluster structure. |

Extracting data from pictures of medical records is a common task in the insurance industry as the patients often send their medical invoices taken by smartphone cameras. However, the overall process is still challenging to be fully automated because of low image quality and variation of templates that exist in the status quo. In this paper, we propose a mixed-initiative pipeline for extracting data from pictures of medical invoices, where deep-learning-based automatic prediction models and task-specific heuristics work together under the mediation of a user. In the user study with 12 participants, we confirmed our mixed-initiative approach can supplement the drawbacks of a fully automated approach within an acceptable completion time. We further discuss the findings, limitations, and future works for designing a mixed-initiative system to extract data from pictures of a complicated table. |

Progressive Uniform Manifold Approximation and Projection

paper /
code /
talk /
bibtex /
doi
We present a progressive algorithm for the Uniform Manifold Approximation and Projection (UMAP), called the Progressive UMAP. Based on the theory of Riemannian geometry and algebraic topology, UMAP is an emerging dimensionality reduction technique that offers better versatility and stability than t-SNE. Although UMAP is also more efficient than t-SNE, it still suffers from an initial delay of a few minutes to produce the first projection, which limits its use in interactive data exploration. To tackle this problem, we improve the sequential computations in UMAP by making them progressive, which allows people to incrementally append a batch of data points into the projection at the desired pace. In our experiment with the Fashion MNIST dataset, we found that Progressive UMAP could generate the first approximate projection within a few seconds while also sufficiently capturing the important structures of the high-dimensional dataset. |

Iraqi PM To Resign After Deadly Protests
Iraqi Prime Minister Adil-Abdel Mahdi says he will resign, after nearly two months of anti-government protests that have cost more than 400 lives.
Mahdi said in a statement on November 29 he would submit his letter of resignation to parliament so lawmakers could select a new government.
Mahdi, 77, took office just over a year ago. The statement did not say when his resignation would occur.
Earlier in the day, Iraq's top Shi'ite cleric, Grand Ayatollah Ali al-Sistani, condemned the use of force against protesters and called for lawmakers to drop their support for the current cabinet and also urged demonstrators to reject acts of violence and vandalism.
The call came a day after more than 40 people were reported killed in one of the bloodiest days of protests.
Iraqis have been taking to the streets of Baghdad and the country’s Shi'ite-majority south since early October to demand more jobs, an end to endemic corruption, and improved public services.
In remarks delivered by his representative during a televised Friday Prayers sermon in the city of Karbala, Sistani said the government appeared to have been "unable to deal with the events of the past two months."
"Parliament, from which the current government emerged, must reconsider its choices and do what's in the interest of Iraq," the cleric said.
UN Secretary-General Antonio Guterres said he was "deeply concerned over reports of the continued use of live ammunition against demonstrators."
On November 29, casualties were reported in clashes between protesters and security forces in Nasiriyah, where most of the deaths the day before occurred.
There were also reports that protesters were killed in Baghdad.
On November 28 in Nasiriyah, at least 25 people were killed when security forces used live ammunition and tear gas to clear two bridges occupied by protesters, while demonstrators torched a police station, according to medics and security sources.
Reports said live rounds were also fired at Baghdad's Ahrar Bridge as protesters tried to cross toward the Green Zone that hosts parliament and government buildings. Four people were reported killed.
Four more people were reported killed in clashes the southern city of Najaf.
The Iraqi military said on November 28 that "crisis cells" were set up in several provinces to try to "impose security and restore order."
The U.S. State Department said it shared the protesters' "legitimate concerns" and urged the Iraqi government to "advance the reforms demanded by the people, including those that address unemployment, corruption, and electoral reform."
It did not comment directly on Mahdi's decision to quit.


In 2014, I was hired at The Second City, the historic comedy club, theatre and school of improvisation, as a design intern. Since then, I have grown from intern, to Jr. Designer, to Designer and mentor on a team of five. As part of a small design team in a multifaceted company, I’ve been able to have a hand in almost every department across the globe and cater my position to areas I’ve seen need, potential, and had personal interest with both internal and external clients. A few of my favorite projects and products are discussed below.
Brand, Marketing & Art Direction
I was fortunate enough to have a hand in shaping a major rebrand across all branches of the company. One of my primary roles on the team is as the lead designer of the general second city brand and stages for both Chicago and Toronto. Under this role I have collaborated with our marketing team to develop and execute several brand awareness, microsites, show campaigns, and UI mockups for various target audiences. Because of the variety in projects and stakeholders, flexibility and agility is key when it comes to deciding how to handle each process. Several in-depth campaigns upon request.
The Second City Network
Along with the VP of New Media at The Second City, I became a point person for the communication of goals regarding the resign of the Network. The goal and challenge was to first and foremost educate the user about what the Second City Network is. I started researching client needs, user journeys, wireframing pages, helping with quality control and page speed, and discussing our user experience needs and information architecture with the contractor. In addition, I helped rebrand the channel and created a variety of end cards to increase audience retention and engagement.
sctv.com
Our Toronto steakholders expressed the need for a product that showed off SCTV to potential clients interested in our SCTV archive. The goal was to showcase the history of SCTV Network, its actors, and the legacy the show and actors have left behind. I served as the lead creative director for the project and the sole designer and developer. Using an existing WordPress theme, I reworked the site with custom code to better fit the needs of the client.

These versions use various coding techniques like, from inline Spry attributes to progressive enhancement for graceful degradation. DIfferent coders have different goals and these sample show various ways to accomplish the same end product..
This version uses XML data and inline Spry attributes to generate the markup. This demonstrates how to build a HTML template. It also showcases multiple dependent data sets. With javascript off, it does not degrade gracefully.
This version has been updated to use more modular code. The thumbnail region and the main image region have been written to act as widgets, with some code to bind them together. This makes the gallery easier to disassemble and modify. It also uses the XML Data set.
This uses progressive enhancement to add animations and additional functionality to static content. No Spry Data Sets are used; only the modular code pieces used in version 2 and the Element Selector do the work. This is a useful technique if the static content already exists and you want to upgrade the user experience. This also degrade nicely when javascript is turned off.
Using inline content as a data source and using regions to change the look and feel of the gallery. Using internal HTML data sets is helpful with search engine optimization and graceful degradation.
Note: Due to limitations of Safari 2.0, we have not presented a demo that unobtrusively attaches Spry attributes. This is because Safari does not handle adding namespaced attribute. It appears that Safari 3 has solved that limitation. We do have a sample of this technique here and here. Unobtrusively adding Spry attributes is useful when page validation is important.
This version of the Photo Gallery shows how the page should be coded for Adobe AIR. Check this code against the original version to see what changes were made. This is just the sample code. Please read the AIR packaging readme in order to learn more on how to build the AIR package.

Farm Game
问题描述 :
“Farm Game” is one of the most popular games in online community. In the community each player has a virtual farm. The farmer can decide to plant some kinds of crops like wheat or paddy, and buy the corresponding crop seeds. After they grow up, The farmer can harvest the crops and sell them to gain virtual money. The farmer can plant advanced crops like soybean, watermelon or pumpkin, as well as fruits like lychee or mango.
Feeding animals is also allowed. The farmer can buy chicken, rabbits or cows and feeds them by specific crops or fruits. For example, chicken eat wheat. When the animals grow up, they can also “output” some products. The farmer can collect eggs and milk from hens and cows. They may be sold in a better price than the original crops.
When the farmer gets richer, manufacturing industry can be set up by starting up some machines. For example, Cheese Machine can transfer milk to cheese to get better profits and Textile Machine can spin cony hair to make sweaters. At this time, a production chain appeared in the farm.
Selling the products can get profits. Different products may have different price. After gained some products, the farmer can decide whether to sell them or use them as animal food or machine material to get advanced products with higher price.
Jack is taking part in this online community game and he wants to get as higher profits as possible. His farm has the extremely high level so that he could feed various animals and build several manufacturing lines to convert some products to other products.
In short, some kinds of products can be transformed into other kinds of products. For example, 1 pound of milk can be transformed into 0.5 pound of cheese, and 1 pound of crops can be transformed into 0.1 pound of eggs, etc. Every kind of product has a price. Now Jack tell you the amount of every kind of product he has, and the transform relationship among all kinds of products, please help Jack to figure out how much money he can make at most when he sell out all his products.
Please note that there is a transforming rule: if product A can be transformed into product B directly or indirectly, then product B can never be transformed into product A, no matter directly or indirectly.
输入:
The input contains several test cases. The first line of each test case contains an integers N (N<=10000) representing that there are N kinds of products in Jack’s farm. The product categories are numbered for 1 to N. In the following N lines, the ith line contains two real numbers p and w, meaning that the price for the ith kind of product is p per pound and Jack has w pounds of the ith kind of product.
Then there is a line containing an integer M (M<=25000) meaning that the following M lines describes the transform relationship among all kinds of products. Each one of those M lines is in the format below:
K a0, b1, a1, b2, a2, …, bk-1, ak-1
K is an integer, and 2×K-1 numbers follows K. ai is an integer representing product category number. bi is a real number meaning that 1 pound of product ai-1 can be transformed into bi pound of product ai.
The total sum of K in all M lines is less than 50000.
The input file is ended by a single line containing an integer 0.

示例程序中的代码不够稳健，没有考虑到输入了非法字符或者不合理输入的情况。
不同的编译器，printf(),执行的顺序不同，所以结果也就不同，建议不要那么写
第二个方法挺不错。NewHead代表新的头节点，通过递归找到最后一个节点之后，就把这个节点赋给NewHead，然后一直返回返回，中途这个值是没有变化的，一边返回一边把相应的指针方向颠倒，最后结束时返回新的头节点到主函数。
代码不对，仔细对比一下输入输出， 怎么会有‘‘printf("The winning moves are:");’’这种输出呢？
程序只能输出一个子序列

问题3是不是应该为1/4 .因为截取的三段，无论是否能组成三角形， x， y-x ，1-y,都应大于0，所以 x<y,基础应该是一个大三角形。小三角是大三角的 1/4.
多谢指出，已改正
这一题的代码这样提交时错误的~少考虑了很多情况
为什么for循环找到的i一定是素数叻，而且约数定理说的是n=p1^a1*p2^a2*p3^a3*…*pk^ak，而你每次取余都用的是原来的m，也就是n

cron is driven by a crontab, a configuration file that specifies shell commands to run periodically on a given schedule.
crontab syntax
Each line in a crontab file is a job and follows a particular format as a series of fields, separated by spaces or tabs(see example below). Each field can have a single value or a series of values.
crontab Operators
There are multiple ways of specifying several date/time values in a field:
- The comma(,) specifies a list of values, for example: "1,3,4,7,8"
- The dash(-) specifies a range. Example: "1-6", which is equivalent to "1,2,3,4,5,6"
- The asterisk(*) operator specifies all possible values for a field. For example, an asterisk in the hour time field would be the same as 'every hour'.
There is also an operator which some extended versions of cron support, the slash(/) operator, which can be used to skip a given number of values. For example, "*/3" in the hour time field is equivalent to "0,3,6,9,12,15,18,21". So "*" specifies 'every hour' but the "*/3" means only those hours divisible by 3.
Example: the following will clear the Apache error log at one minute past midnight each day.
01 00 * * * echo "" > /www/apache/logs/error_log
Fields
.---------------- minute (0 - 59) | .------------- hour (0 - 23) | | .---------- day of month (1 - 31) | | | .------- month (1 - 12) OR jan,feb,mar,apr ... | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat | | | | | * * * * * <command to be executed>

Off on a Comet
by Jules Verne
Introduction to the story
AMONG so many effective and artistic tales of our author, it is difficult to give a prefer- ence to one over all the rest. Yet, certainly, even amid Verne's most remarkable works, his "Off on a Comet" must be given high rank. Perhaps this story will be remembered when some of his greatest efforts have been obliterated by centuries of time. At least, of the many books since written upon the same theme as Verne's, no one has yet equaled or even approached it.
In one way "Off on a Comet" shows a marked contrast to Verne's earlier books. Not only does it invade a region of remotest space, but the author here abandons his usual scrupidously scientific attitude and gives his fancy freer rein. In order that he may escort us through the depths of immeasur- able space, to show us what astronomy really knoius of conditions there and upon the other planets, Verne asks us to accept a situation which is in a sense self-contradictory. The earth and a comet are brought twice into collision without mankind in gen- eral, or even our astronomers, becoming conscious of the fact. Moreover several people from widely scattered places are carried off by the comet and returned uninjured. Yet further, the comet snatch- es and carries a way with it for the convenience of its travelers, both air and water. Little, useful tracts of earth are picked up and, as it were, turned over and clapped down right side up again upon the comet's surface. Even ships pass uninjured through this remarkable somersault. These events all belong to the realm of fairyland.
If the situation were reproduced in actuality, if, ever a comet should come into collision with the earth, we can conceive two scientifically possible results. If the comet were of such attenuation, such almost infinitesimal mass as some of these celestial wanderers seem to be, we can imagine our earth self- protective and possibly unharmed. If, on the other hand, the comet had even a hundredth part of the size and solidity and weight which Verne confers upon his monster so as to give his travelers a home in that case the collision woidd be unspeakably disastrous - especially to the unlucky individuals who occupied the exact point of contact.
But once granted the initial and the closing ex- travagance, the departure and return of his charac- ters, the alpha and omega of his tale, hoxo closely the author clings to facts between! How closely he fol- lows, and imparts to his readers, the scientific proba- bilities of the universe beyond our earth, the actual knoivledge so hard won by our astronomers! Other authors who, since Verne, have told of trips through the planetary and stellar universe have given free rein to fancy, to dreams of what might be found. Verne has endeavored to impart only what is known to exist.
In the same year with "Off on a Comet," 1877, was published also the tale variously named and trans- lated as "The Black Indies," "The Underground City" and "The Child of the Cavern," This story, like "Round the World in Eighty Days" was first issued in "feuilleton" by the noted Paris newspaper "Le Temps." Its success did not equal that of its predecessor in this style. Some critics indeed have pointed to this work as marking the beginning of a decline in the author's pou'er of awaking interest. Many of his best works were, however, still to follow.

Mortal Kombat 11 Review
Platforms: Xbox One, PS4, PC, Nintendo Switch, Google Stadia
Developers: NetherRealm Studios
Publishers: Warner Bros. Interactive Enterttainment
Release: April 23, 2019
Rating: M
Reviewed: December 4, 2019 Xbox One
Description: Mortal Kombat 11 is the latest installment in the critically acclaimed franchise, providing a deeper and more personalized experience than ever before with an all new Custom Character Variation System that gives players the creative control to customize versions of the entire character roster. Developed by award-winning NetherRealm Studios, Mortal Kombat 11 will introduce a new cinematic story continuing the epic saga that is more than 25 years in the making. All-New Custom Character Variation System: Offers nearly infinite customization options, giving players more control and providing a deeper and more personalized experience than ever before. Players can customize their fighters with a variety of Skins, Gear, Special Abilities, Intro and Victory Cinemas, Taunts and Brutalities that can be earned via gameplay. All-New Story Mode: Continue the epic saga through a new cinematic story that is more than 25 years in the making. Players will take on the role of a variety of past and present characters in a time-bending new narrative that pits Raiden against Kronika, the Keeper of Time who created existence at the dawn of history. New & Returning Fan-Favorite Characters: Choose from a roster of fighters with unique abilities and Fatalities, with new characters, such as Geras, a powerful and loyal servant of Kronika who can manipulate time, along with fan-favorite characters, including, Baraka, Raiden, Skarlet, Scorpion, Sonya Blade and Sub-Zero and more. More Modes, Challenges & Rewards: Packed to the brim with multiple modes, including the Towers of Time, which builds upon NetherRealms's past games, allowing players to test their skills through various challenges, providing more ways than ever to continue the Mortal Kombat 11 experience.
Gameplay: The best aspect of this game is the gameplay. Whether you played any previous Mortal Kombat iterations or not, this game will entice
any fighting game enthusiast. Not to mention, the learning curve in this game is almost non-existent so beginners will also be able to
enjoy this game. Personally, I have played Mortal Kombat (2011) and Mortal Kombat X and I have to say that Mortal Kombat 11 has improved
drastically in the gameplay department. Objectives in fighting games are simple: defeat your opponent. In Mortal Kombat 11, not only
can you defeat your opponent, but you can finish them off as well in a variety of unique ways. These include Fatalities that occur
at the end of the battle that requires the player to enter a specific combination of button inputs to begin a sequence where your
character proceeds to murder your opponent. Brutalities are essentially different versions of combos or moves that are performed
as the last one performed before victory after meeting certain requirements like press down, down, down as you do a grab.
Varying between the ways you can finish an opponent never gets old! New to the series are varied character intro and outros which is also
refreshing. Another new feature is the re-work of the enhanced special move bar. In Mortal Kombat X, your X-Ray attack cost three bars
of a meter that had to be shared to enhance special moves as well. In Mortal Kombat 11, they have changed the X-Ray attack to the Fatal
Blow that doesn't cost any bars of your meter and can only be performed when you are below a certain health threshold. This
mechanic is great for making a comeback in a losing round or match. The enahnced special move bar has also been changed to include
two bars for both offensive and defensive options. If you want to enhance a combo, it uses the offensive bar. If you want to escape
a punishing combo, you can do so at the expense of your defensive bar. This allows for a better experience in a fighting game that allow
players of all skill base to do well in it and subsequently enjoy the game more now that they can do those high damage combos and win.
In terms of combos and execution of them, it is fairly easy compared to other fighting games like Marvel vs Capcom. There is no combo
string that I couldn't perform without much trouble. However, if you want to do complex combos that string together multiple combos
and move cancels, you will have to look those up for their timing and specific execution. Once you do, it shouldn't be impossible to pull
them off. Mortal Kombat 11 has also included a new Krushing Blow system that enhances a certain move or combo string to show an attack
similar to an X-Ray from Mortal Kombat X and allows players to do more damage and sometimes even perform more combos afterward. Similar to
Brutalities, Krushing Blows can only be initiated after completing a certain set of requirements beforehand. The environment can
also be used to your advantage like using a weapon that is lying around or a platform to jump across the screen with.
Overall, all of these new changesto gameplay mechanics are an overwhelming positive addition to the franchise and a worth a lot of praise.
However, like all fighting games, the character roster also suffers from character balancing. Some characters are so much better than others
that it renders some other characters as unplayable due to an improper balancing. Fortunately, not many characters are too overpowered that
no character other than them can defeat them. As long as you learn your character, how they play, how fast they are at blocking, attacking,
recovering, and their moves, you should be fine. Just stay away from Liu Kang players! Otherwise, the gameplay is solid in this
installment in the franchise.
Single-Player/Campaign/Story: Mortal Kombat 11 has a lot to offer in terms of Single-Player content including a full-fledged
story mode, local fights, the Krypt, and Klassic Towers. The story mode is my favorite out of all these modes because it not only
continues the story of Mortal Kombat X, but takes risks in developing this story. In other words, NetherRealm isn't shy from
dispensing certain characters from existence. The whole theme of the story is time manipulation enacted by an elder god named Kronika
to change the timeline of the Mortal Kombat franchise including the future. This plotline makes it easy for NetherRealm to bring back
fan favorites who previously died or change he current roster of characters as well. Generally, you will be playing as multiple main characters
from Earthrealm trying to stop Kronika and are at times given the option to select who you play as from a choice of two characters. I appreciate
being given the option since most games don't these days. I also appreciate the new characters that Mortal Kombat 11 introduces as well as
their background as it gives players reason to play as these characters in other modes. There was not a single point in the story that I
wanted to stop playing. I was actually left wanting more after I completed it! The conclusion is as expected to setup potential for a sequel
which will most definitely happen at some point in the future, but don't expect it to be released until after Injustice 3 is released
as this seems to be the release schedule pattern NetherRealm Studios is going with in recent memory.
In terms of the Krypt, it is a more expansive version of previous iterations and is much more complex to get everything inside of it.
Essentially, the Krypt is Mortal Kombat 11's way of obtaining gear, skins, consumables/modifiers, concept art and other collectibles.
In order to unlock these items you need to open chests that take one of three currencies: Koins, hearts, and soul fragments. These
chests for the most part contain random contents of the aforementioned items except for the Shao Kahn Chests that have pre-determined
items for specific characters. I do not like that these chests are random as it makes the grind worse to obtain the currency just to open
them let alone get what you want. However, it isn't impossible to get everything as I pretty much do, it just takes time. My only real
complaint is that in order to collect all gear, skins, brutalities, etc. you need to have an online connection and membership with your
respective platform to play Towers of Time. In order to get the most out of the Krypt, you will need to collect certain items and do certain
tasks in order to unlock certain sections of the Krypt. The tasks themselves are great because they remove the repetitive nature of opening chests.
However, don't think that you can not die in the Krypt because you certainly can from anything from spiders to traps and even meteors falling
from the sky! Definitely an immersive mode to unlock other forms of content in a game.
Klassic Towers are traditional Mortal Kombat towers that allow players to play against a random assortment of characters to either unlock their
respective character's ending or to just see how long they can survive in an endless tower or survival tower where health isn't fully replenished.
These are nice to have to add replayability, but are overshadowed by its online version, Towers of Time. However, these towers are great
to complete certain challenges for character towers in Towers of Time!
Multiplayer: Multiplayer is split into multiple components: Towers of Time, Ranked matches, Kasual matches and different
variations of online matches like King of the Hill lobbies. Towers of Time is essentially an online version of Klassic Towers that
rotate based on time of day, day of the week, etc. These towers are how players primarily will get character brutalities, taunts,
intros and outros with the addition of a lot of gear too. It is frustrating that most of these things are behind an online wall, but
at this point most companies assume you are playing video games online nowadays. Some towers require you to play with only a certain character
while others require you to complete them with other players cooperatively. All while gameplay modifiers are active like character
armor or random missiles being launched at you! However, you can deploy your own modifiers as well to decrease the difficulty of these
towers. Lastly, character towers are a part of Towers of Time that act as challenges for playing as a ceratin character to unlock towers
based on that character to unlock respective gear, brutalities, intros and outros. Most of your time in Mortal Kombat 11 after completing
the story will be spent here. I am happy to report that for the most part I had fun doing these towers, but also admit that I used an
AI loadout to fight for me when I wasn't feeling it.
Ranked matches are what you would expect them to be, matches that affect your ranking in the online ranked seasons and leaderboards.
Ranked seasons are themed differently and reward players with skins and gear. However, the matchmaking system is quite unfair and broken
at times. If a player shuts off their console or goes to the dashboard mid-match, you will most likely be greeted with a message that
connection has been lost instead of player quitting which doesn't always result in a deserved win and is very frustrating after almost
winning. Another flaw of ranked is the tendency to be placed against players that are not on the same skill level as you and usually leads
to an utter defeat. This is probably the most frustrating thing about ranked since it touts that it matchmakes based on skill when it clearly
doesn't. That is why there is the option of Kasual matches and King of the Hill matches! King of the Hill is mainly a lobby of players that
fight to become the "King" and everyone else tries their turn at dethroning them and claiming the title for themselves. I would suggest
these two modes to players if they are not that good at the game as ranked will turn off these players if they ignore this warning.

I had to keep saying to myself "process over product". I felt intimidated at the beginning of the week when a few of my fellow cohort posted amazing websites. I tried to take inspiration from them, but starting focusing too much on the product and quickly become very frustated by my inability to firstly design a site them implement. I spent alot of time on the product and not the process this week...steep learning curve.
These days everyone is in a hurry to get somewhere. People rarely stop and focus on the present moment without judgement. I frequently fall into this sinking ship. I think meditation is an amazing way to slow down and gain control of your mind. I try to practice on a daily basis when I have enough self control.. My understanding of meditation is: Mental training to improve attention awareness.
Happiness need not be pursued, but allowed. It is a default state of mind and meditation calms the mind to allow. I like the analogy of the gym and weight lifting. Everytime you lift a weight, the resistance increases muscle strength. Everytime your mind wanders and you bring it back to present you are building 'mental muscle' and improving your attention to the present moment.
Yeah - I like the process model which features the question before you start - what is my intention here? Why am I meditating? I also found the attitude concept good, adopting the 'grandmother mind' when talking to youself.
The pursuit of happiness is interesting as are the studies conducted which show improvements in anxiety levels and immune system strength after 8 weeks of consistent meditation.

endpath(draw=True)
The endpath() command is the companion to beginpath() and may only be called after the latter. When endpath() is called, the path (defined by commands between beginpath() and endpath()) is drawn to the screen. If called with draw=False
, the path is not drawn to the screen but can be assigned to a variable. Later on, the variable can be drawn with the drawpath() command.
The endpath() command has been subsumed into the new bezier() command. Rather than calling beginpath() and endpath() to construct beziers, you can call bezier() as part of a with
statement.

What's new in Miller 6¶
User experience¶
Features are driven largely by great feedback in the 2021 Miller User Survey results and GitHub Issues.
TL;DRs: install, binaries, compatibility with Miller 5.
Performance¶
Performance is on par with Miller 5 for simple processing, and is far better than Miller 5 for complex processing chains -- the latter due to improved multicore utilization. CSV I/O is notably improved. See the Performance benchmarks section at the bottom of this page for details.
Documentation improvements¶
Documentation (what you're reading here) and online help (mlr --help
) have been completely reworked.
In the initial release, the focus was convincing users already familiar with
awk
/grep
/cut
that Miller was a viable alternative -- but over time it's
become clear that many Miller users aren't expert with those tools. The focus
has shifted toward a higher quantity of more introductory/accessible material
for command-line data processing.
Similarly, the FAQ/recipe material has been expanded to include more, and simpler, use-cases including resolved questions from Miller Issues and Miller Discussions; more complex/niche material has been pushed farther down. The long reference pages have been split up into separate pages. (See also Structure of these documents.)
One of the main feedback themes from the 2021 Miller User Survey was that some things should be easier to find. Namely, on each doc page there's now a banner across the top with things that should be one click away from the landing page (or any page): command-line flags, verbs, functions, glossary/acronyms, and a finder for docs by release.
Since CSV is overwhelmingly the most popular data format for Miller, it is now discussed first, and more examples use CSV.
Improved Windows experience¶
Stronger support for Windows (with or without MSYS2), with a couple of exceptions. See Miller on Windows for more information.
Binaries are reliably available using GitHub Actions: see also Installation.
Output colorization¶
Miller uses separate, customizable colors for keys and values whenever the output is to a terminal. See Output Colorization.
Improved command-line parsing¶
Miller 6 has getoptish command-line parsing (pull request 467):
-xyz
expands automatically to-x -y -z
, so (for example)mlr cut -of shape,flag
is the same asmlr cut -o -f shape,flag
.--foo=bar
expands automatically to--foo bar
, so (for example)mlr --ifs=comma
is the same asmlr --ifs comma
.--mfrom
,--load
,--mload
as described in the flags reference.
A small but nice item: since mlr --csv and mlr --json are so common, you can now use alternate shorthands mlr -c and mlr -j, respectively.
Improved error messages for DSL parsing¶
For mlr put
and mlr filter
, parse-error messages now include location information:
mlr: cannot parse DSL expression. Parse error on token ">" at line 63 columnn 7.
Scripting¶
Scripting is now easier -- support for #!
with sh
, as always, along with now support for #!
with mlr -s
. For
Windows, mlr -s
can also be used. These help reduce backslash-clutter and let you do more while typing less.
See the scripting page.
REPL¶
Miller now has a read-evaluate-print-loop (REPL) where you can single-step through your data-file record, express arbitrary statements to converse with the data, etc.
mlr repl
[mlr] 1 + 2 3 [mlr] apply([1,2,3,4,5], func(e) {return e ** 3}) [1, 8, 27, 64, 125] [mlr] :open example.csv [mlr] :read [mlr] $* { "color": "yellow", "shape": "triangle", "flag": "true", "k": 1, "index": 11, "quantity": 43.6498, "rate": 9.8870 }
Localization and internationalization¶
Improved internationalization support¶
You can now write field names, local variables, etc. all in UTF-8, e.g. mlr
--c2p filter '$σχήμα == "κύκλος"' παράδειγμα.csv
. See the
internationalization page for examples.
Improved datetime/timezone support¶
Including support for specifying timezone via function arguments, as an alternative to
the TZ
environment variable. Please see DSL datetime/timezone functions.
Data ingestion¶
In-process support for compressed input¶
In addition to --prepipe gunzip
, you can now use the --gzin
flag. In fact, if your files end in .gz
you don't even need to do that -- Miller will autodetect by file extension and automatically uncompress mlr --csv cat foo.csv.gz
. Similarly for .z
and .bz2
files. Please see the page on Compressed data for more information.
Support for reading web URLs¶
You can read input with prefixes https://
, http://
, and file://
:
mlr --csv sort -f shape \ https://raw.githubusercontent.com/johnkerl/miller/main/docs/src/gz-example.csv.gz
color,shape,flag,k,index,quantity,rate red,circle,true,3,16,13.8103,2.9010 yellow,circle,true,8,73,63.9785,4.2370 yellow,circle,true,9,87,63.5058,8.3350 red,square,true,2,15,79.2778,0.0130 red,square,false,4,48,77.5542,7.4670 red,square,false,6,64,77.1991,9.5310 purple,square,false,10,91,72.3735,8.2430 yellow,triangle,true,1,11,43.6498,9.8870 purple,triangle,false,5,51,81.2290,8.5910 purple,triangle,false,7,65,80.1405,5.8240
Data processing¶
Improved JSON / JSON Lines support, and arrays¶
Arrays are now supported in Miller's put
/filter
programming language, as
described in the Arrays reference. (Also, array
is
now a keyword so this is no longer usable as a local-variable or UDF name.)
JSON support is improved:
- Direct support for arrays means that you can now use Miller to process more JSON files than ever before.
- Streamable JSON parsing: Miller's internal record-processing pipeline starts as soon as the first record is read (which was already the case for other file formats). This means that, unless records are wrapped with outermost
[...]
, Miller now handles JSON / JSON Lines intail -f
contexts like it does for other file formats. - Flatten/unflatten -- conversion of JSON nested data structures (arrays and/or maps in record values) to/from non-JSON formats is a powerful new feature, discussed in the page Flatten/unflatten: JSON vs. tabular formats.
- Since types are better handled now, the workaround flags
--jvquoteall
and--jknquoteint
no longer have meaning -- although they're accepted as no-ops at the command line for backward compatibility.
JSON vs JSON Lines:
- Miller 5 accepted input records either with or without enclosing
[...]
; on output, by default it produced single-line records without outermost[...]
. Miller 5 let you customize output formatting using--jvstack
(multi-line records) and--jlistwrap
(write outermost[...]
). Thus, Miller 5's JSON output format, with default flags, was in fact JSON Lines all along. - In Miller 6, JSON Lines is acknowledged explicitly.
- On input, your records are accepted whether or not they have outermost
[...]
, and regardless of line breaks, whether the specified input format is JSON or JSON Lines. (This is similar to jq.) - With
--ojson
, output records are written multiline (pretty-printed), with outermost[...]
. - With
--ojsonl
, output records are written single-line, without outermost[...]
. - This makes
--jvstack
and--jlistwrap
unnecessary. However, if you want outermost[...]
with single-line records, you can use--ojson --no-jvstack
.
See also the Arrays reference for more information.
Improved numeric conversion¶
The most central part of Miller 6 is a deep refactor of how data values are parsed from file contents, how types are inferred, and how they're converted back to text into output files.
This was all initiated by https://github.com/johnkerl/miller/issues/151.
In Miller 5 and below, all values were stored as strings, then only converted
to int/float as-needed, for example when a particular field was referenced in
the stats1
or put
verbs. This led to awkwardnesses such as the -S
and -F
flags for put
and filter
.
In Miller 6, things parseable as int/float are treated as such from the moment the input data is read, and these are passed along through the verb chain. All values are typed from when they're read, and their types are passed along. Meanwhile the original string representation of each value is also retained. If a numeric field isn't modified during the processing chain, it's printed out the way it arrived. Also, quoted values in JSON strings are flagged as being strings throughout the processing chain.
For example (see https://github.com/johnkerl/miller/issues/178) you can now do
echo '{ "a": "0123" }' | mlr --json cat
[ { "a": "0123" } ]
echo '{ "x": 1.230, "y": 1.230000000 }' | mlr --json cat
[ { "x": 1.230, "y": 1.230000000 } ]
Deduping of repeated field names¶
By default, field names are deduped for all file formats except JSON / JSON Lines. So if you
have an input record with x=8,x=9
then the second field's key is renamed to
x_2
and so on -- the record scans as x=8,x_2=9
. Use mlr
--no-dedupe-field-names
to suppress this, and have the record be scanned as
x=9
.
For JSON and JSON Lines, the last duplicated key in an input record is always retained,
regardless of mlr --no-dedupe-field-names
: {"x":8,"x":9}
scans as if it
were {"x":9}
.
Regex support for IFS and IPS¶
You can now split fields on whitespace when whitespace is a mix of tabs and spaces. As well, you can use regular expressions for the input field-separator and the input pair-separator. Please see the section on multi-character and regular-expression separators.
In particular, for NIDX format, the default IFS now allows splitting on one or more of space or tab.
Case-folded sorting options¶
The sort verb now accepts -c
and -cr
options for case-folded ascending/descending sort, respetively.
New DSL functions / operators¶
-
Higher-order functions
select
,apply
,reduce
,fold
, andsort
. See the sorting page and the higher-order-functions page for more information. -
Absent-coalesce operator
??
along with??=
; absent-empty-coalesce operator???
along with???=
. -
The dot operator is not new, but it has a new role: in addition to its existing use for string-concatenation like
"a"."b" = "ab"
, you can now also use it for keying maps. For example,$req.headers.host
is the same as$req["headers"]["host"]
. See the dot-operator reference for more information. -
Unsigned right-shift
>>>
along with>>>=
.

Changes from Miller 5¶
The following differences are rather technical. If they don't sound familiar to you, not to worry! Most users won't be affected by the (relatively minor) changes between Miller 5 and Miller 6.
Please drop an issue at https://github.com/johnkerl/miller/issues with any/all backward-compatibility concerns between Miller 5 and Miller 6.
Line endings¶
The --auto
flag is now ignored. Before, if a file had CR/LF (Windows-style) line endings on input (on any platform), it would have the same on output; likewise, LF (Unix-style) line endings. Now, files with CR/LF or LF line endings are processed on any platform, but the output line-ending is for the platform. E.g. reading CR/LF files on Linux will now produce LF output.
IFS and IPS as regular expressions¶
IFS and IPS can be regular expressions now. Please see the section on multi-character and regular-expression separators.
JSON and JSON Lines formatting¶
--jknquoteint
andjquoteall
are ignored; they were workarounds for the (now much-improved) type-inference and type-tracking in Miller 6.--json-fatal-arrays-on-input
,--json-map-arrays-on-input
, and--json-skip-arrays-on-input
are ignored; Miller 6 now supports arrays fully.- See also
mlr help legacy-flags
or the legacy-flags reference. - Miller 5 accepted input records either with or without enclosing
[...]
; on output, by default it produced single-line records without outermost[...]
. Miller 5 let you customize output formatting using--jvstack
(multi-line records) and--jlistwrap
(write outermost[...]
). Thus, Miller 5's JSON output format, with default flags, was in fact JSON Lines all along. - In Miller 6, JSON Lines is acknowledged explicitly.
- On input, your records are accepted whether or not they have outermost
[...]
, and regardless of line breaks, whether the specified input format is JSON or JSON Lines. (This is similar to jq.) - With
--ojson
, output records are written multiline (pretty-printed), with outermost[...]
. - With
--ojsonl
, output records are written single-line, without outermost[...]
. - This makes
--jvstack
and--jlistwrap
unnecessary. However, if you want outermost[...]
with single-line records, you can use--ojson --no-jvstack
. - Miller 5 tolerated trailing commas, which are not compliant with the JSON specification: for example,
{"x":1,"y":2,}
. Miller 6 uses a JSON parser which is compliant with the JSON specification and does not accept trailing commas.
Type-inference¶
- The
-S
and-F
flags tomlr put
andmlr filter
are ignored, since type-inference is no longer done inmlr put
andmlr filter
, but rather, when records are first read. You can usemlr -S
andmlr -A
, respectively, instead to control type-inference within the record-readers. - Octal numbers like
0123
and07
are type-inferred as string. Usemlr -O
to infer them as octal integers. Note that08
and09
will then infer as decimal integers. - Any numbers prefix with
0o
, e.g.0o377
, are already treated as octal regardless ofmlr -O
--mlr -O
only affects how leading-zero integers are handled. - See also the miscellaneous-flags reference.
Emit statements¶
Variables must be non-indexed on emit
. To emit an indexed variable now requires the new emit1
keyword.
This worked in Miller 5 but is no longer supported in Miller 6:
mlr5 -n put 'end {@input={"a":1}; emit @input["a"]}'
input=1
This works in Miller 6 (and worked in Miller 5 as well) and is supported:
mlr -n put 'end {@input={"a":1}; emit1 {"input":@input["a"]}}'
input=1
Please see the section on emit statements for more information.
Developer-specific aspects¶
- Miller has been ported from C to Go. Developer notes: https://github.com/johnkerl/miller/blob/main/README-dev.md.
- Regression testing has been completely reworked, including regression-testing now running fully on Windows (alongside Linux and Mac) on each GitHub commit.
Performance benchmarks¶
For performance testing, the example.csv file was expanded into a million-line CSV file, then converted to DKVP, JSON, etc.
Notes:
- These benchmarks were run on two laptops: a commodity Mac laptop with four CPUs, on MacOS Monterey, using
go1.16.5 darwin/amd64
, and a commodity Linux Lenovo with eight CPUs, on Ubuntu 21.10, usinggo1.17.5 linux/amd64
. - Interestingly, I noted a significant slowdown -- for this particular Linux laptop on low battery -- for the Go version but not the C version. Perhaps multicore interacts with power-saving mode.
- As of late 2021, Miller has been benchmarked using Go compiler versions 1.15.15, 1.16.12, 1.17.5, and 1.18beta1, with no significant performance changes attributable to compiler versions.
For the first benchmark, the format is CSV and the operations are varied:
Mac
| Operation | Miller 5 | Miller 6 | Speedup |
|---|---|---|---|
| CSV check | 1.541 | 1.216 | 1.27x |
| CSV cat | 2.403 | 1.430 | 1.68x |
| CSV tail | 1.526 | 1.222 | 1.25x |
| CSV tac | 2.785 | 3.122 | 0.89x |
| CSV sort -f shape | 2.996 | 3.139 | 0.95x |
| CSV sort -n quantity | 4.895 | 5.200 | 0.94x |
| CSV stats1 | 2.955 | 1.865 | 1.58x |
| CSV put expressions | 5.642 | 2.577 | 2.19x |
Linux
| Operation | Miller 5 | Miller 6 | Speedup |
|---|---|---|---|
| CSV check | 0.680 | 1.104 | 0.62x |
| CSV cat | 1.066 | 1.231 | 0.87x |
| CSV tail | 0.691 | 1.130 | 0.61x |
| CSV tac | 1.648 | 2.620 | 0.63x |
| CSV sort -f shape | 2.087 | 2.953 | 0.71x |
| CSV sort -n quantity | 5.588 | 5.337 | 1.05x |
| CSV stats1 | 2.376 | 1.751 | 1.36x |
| CSV put expressions | 4.520 | 2.091 | 2.16x |
For the second benchmark, we have mlr cat
of those files, varying file types, with processing times shown. Catting out files as-is isn't a particularly useful operation in itself, but it gives an idea of how processing time depends on file format:
Mac

Notes:
- CSV processing is particularly improved in Miller 6.
- Record I/O is improved across the board, except that JSON continues to be a CPU-intensive format. Miller 6 JSON throughput is the same on Mac and Linux; Miller 5 did better than Miller 6 but only on Linux, not Mac.
- Miller 6's
sort
merits more performance analysis. - Even single-verb processing with
put
andstats1
is significantly faster on both platforms. - Longer then-chains benefit even more from Miller 6's multicore approach.

My name is James and I'm someone who is just stepping into coding. My limited experience would boil down to making websites in the past, but mostly using HTML. So far this has been an interesting learning experience with skills I'd like to see myself use in the future. Outside of this you can usually find me at a buffet. My drink of choice: Soju.
I'm Crystal! My cousin reccomended codefellows to me in 2015, so I took the foundations 1 course while living in Bellingham.
I loved it so much, I decided to move a little closer, and continue my coding education.
When I'm not coding, I enjoy reading, painting, and going on roadtrips. My favorite drink is Patron!
I'm Tre. I like to play ball.  Hopefully they enjoy talking to me, as well. I will fill this with more content when I can get to it. My drink of choice is a sweet, sweet Lemon Drop.
Tracey is a first year code slinger, who is continually questing for new knowledge. In the past, she obtained a BA in Food Science Human Nutrition--Dietetics from WSU. After college, she took some time off and bartended for a couple years. She got a job at a Nutrition Software Company, where her interest in becoming a developer materialized. When not learning code, she can be found making coffee, reading, or traveling. Buy me a drink of: Jameson or Weiss bier

| tidy.glmnet {broom} | R Documentation |
Tidy summarizes information about the components of a model. A model component might be a single term in a regression, a single hypothesis, a cluster, or a class. Exactly what tidy considers to be a model component varies across models but is usually self-evident. If a model has several distinct types of components, you will need to specify which components to return.
## S3 method for class 'glmnet' tidy(x, return_zeros = FALSE, ...)
x |
A |
return_zeros |
Logical indicating whether coefficients with value zero
zero should be included in the results. Defaults to |
... |
Additional arguments. Not used. Needed to match generic
signature only. Cautionary note: Misspelled arguments will be
absorbed in |
Note that while this representation of GLMs is much easier to plot and combine than the default structure, it is also much more memory-intensive. Do not use for large, sparse matrices.
No augment
method is yet provided even though the model produces
predictions, because the input data is not tidy (it is a matrix that
may be very wide) and therefore combining predictions with it is not
logical. Furthermore, predictions make sense only with a specific
choice of lambda.
A tibble::tibble()
with columns:
dev.ratio |
Fraction of null deviance explained at each value of lambda. |
estimate |
The estimated value of the regression term. |
lambda |
Value of penalty parameter lambda. |
step |
Which step of lambda choices was used. |
term |
The name of the regression term. |
