When you dial down the intensity why do you feel dumber? After a few weeks of not meditating I restarted the practice this morning with the Headspace app. I haven't been feeling overwhelmed but just wanted to give meditation another go. It was really calming and throughout the day I felt quite at peace. However, near end of the evening I got a surge of anxiety of under performing. I hadn't, but I had much fewer thoughts in my head through out the day. It felt as if the lack of thoughts and monologues meant that I hadn't worked hard enough today. I suppose that I will get over that feeling as a get back into rhythm with meditation. My anxiety made me go back into the thinking mode, but as expected that didn't not make me happy.
I will be trying Headspace mediation #2 tomorrow for sure to achieve the calm I felt today. Yet I don't think the point of mediation is simply to achieve calmness. I think it is achieve a form of control over our thinking. I believe it can help me better direct and operate my thinking more efficiently. My thoughts reminded me of a quote by Naval Ravikant: "The trick for me now has become how to dial up and down my intensity". I totally resonate with this as sometimes I too intense or too morose.

--- layout: post status: publish published: true title: Modifying the home in PowerShell author: display_name: Tomas Restrepo login: tomasr email<EMAIL_ADDRESS>url: http://winterdom.com/ author_login: tomasr author_email<EMAIL_ADDRESS>author_url: http://winterdom.com/ wordpress_id: 846 wordpress_url: http://winterdom.com/2008/01/modifyingthehomeinpowershell date: '2008-01-24 11:29:23 +0000' date_gmt: '2008-01-24 11:29:23 +0000' categories: - PowerShell tags: [] comments: [] ---
After a long time of procrastinating about it, I finally sat down and started putting together a simple profile script for PowerShell to make it a usable alternative for everyday tasks. It's an excellent shell, but without tweaking it a bit, it can be a bit painful to use at times.
One of the things I wanted to do was modify the global $HOME variable so that it points to my real home folder: one I've configured in the HOME environment variable and that bears no relationship to my user's windows profile directory.
I also wanted PowerShell to use this other folder when resolving filesystem paths starting with "~\", which can be very convenient. Here's what I came up:
#
# Set the $HOME variable for our use
# and make powershell recognize ~\ as $HOME
# in paths
#
set-variable -name HOME -value (resolve-path $env:Home) -force
(get-psprovider FileSystem).Home = $HOME
The first line sets the $HOME variable, and needs the -force switch to do it since it is a read-only variable. The second line simply changes the Home property of the ProviderInfo object for the FileSystem provider (I don't care about how the home gets interpreted in other provider contexts).
On a side note, I also don't keep my real profile script in the default locations used by PowerShell. Instead, I keep my profile script in a file called "_profile.ps1" in, you guessed it, my home folder. Then I simply dot-source it from one of the real profile scripts recognized by PowerShell (such as "c:\users\
. "$env:HOME\_profile.ps1"
Pretty cool stuff, and hopefully this will help me avoid procrastinating so much on making PowerShell my default shell on windows.


RPICSIO
The SPISlaveDeviceHandle Class
The SPISlaveDeviceHandle Class
Provides a container to transport information on an open Slave Device around the system.
The RPI SPI port is capable of 2 slave select lines. This means that if you wish to control more than two devices you will have to use regular GPIO outputs to implement the Slave Selects for them. The RPICSIO SPIPortFS class copes with this and manages it all internally and a slave device configured on a GPIO can be used in exactly the same way as once controlled with the built-in slave select line.
Source Code
The source code for this class is available online for
download
and also in
browseable form.
Example Code
Example code which demonstrates the use of this class can be found on the SPI Port Example page.

public SPISlaveDeviceEnum SPISlaveDevice { get;set }
Get/Set the spiSlaveDevice.
- value
- The SPI Slave Device Enum.


<simpletable>
The <simpletable>
element is used for tables that are regular in
structure and do not need a caption. Choose the <simpletable>
element
when you want to show information in regular rows and columns. For example, multi-column
tabular data such as phone directory listings or parts lists are good candidates for
<simpletable>
. Another good use of <simpletable>
is for information that seems to beg for a three-part definition list; the
@keycol
attribute may be used to indicate which column represents the "key"
or term-like column of your structure.

Introduction
Nearest-neighbors search is a common machine learning task. In this setting, we have a query and a reference dataset. For each point in the query dataset, we wish to know the points in the reference dataset which are closest to the given query point.
Alternately, if the query and reference datasets are the same, the problem can be stated more simply: for each point in the dataset, we wish to know the nearest points to that point.
mlpack provides:
Table of Contents
A list of all the sections this tutorial contains.
Command-Line 'allknn'
The simplest way to perform nearest-neighbors search in mlpack is to use the allknn executable. This program will perform nearest-neighbors search and place the resultant neighbors into one file and the resultant distances into another. The output files are organized such that the first row corresponds to the nearest neighbors of the first query point, with the first column corresponding to the nearest neighbor, and so forth.
Below are several examples of simple usage (and the resultant output). The '-v' option is used so that output is given. Further documentation on each individual option can be found by typing

The 'AllkNN' class
The 'AllkNN' class is, specifically, a typedef of the more extensible NeighborSearch class, querying for nearest neighbors using the Euclidean distance.
typedef NeighborSearch<NearestNeighborSort, metric::EuclideanDistance>
Using the AllkNN class is particularly simple; first, the object must be constructed and given a dataset. Then, the method is run, and two matrices are returned: one which holds the indices of the nearest neighbors, and one which holds the distances of the nearest neighbors. These are of the same structure as the output –neighbors_file and –distances_file for the CLI interface (see above). A handful of examples of simple usage of the AllkNN class are given below.
5 nearest neighbors on a single dataset
using namespace mlpack::neighbor;
extern arma::mat data;
AllkNN a(data);
arma::Mat<size_t> resultingNeighbors;
arma::mat resultingDistances;
a.Search(5, resultingNeighbors, resultingDistances);
The output of the search is stored in resultingNeighbors and resultingDistances.
10 nearest neighbors on a query and reference dataset
using namespace mlpack::neighbor;
extern arma::mat queryData, referenceData;
AllkNN a(referenceData, queryData);
arma::Mat<size_t> resultingNeighbors;
arma::mat resultingDistances;
a.Search(10, resultingNeighbors, resultingDistances);
Naive (exhaustive) search for 6 nearest neighbors on one dataset
This example uses the O(n^2) naive search (not the tree-based search).
using namespace mlpack::neighbor;
extern arma::mat dataset;
AllkNN a(dataset, true);
arma::Mat<size_t> resultingNeighbors;
arma::mat resultingDistances;
a.Search(6, resultingNeighbors, resultingDistances);
Needless to say, naive search can be very slow...
The extensible 'NeighborSearch' class
The NeighborSearch class is very extensible, having the following template arguments:
template<
typename SortPolicy = NearestNeighborSort,
QueryStat<SortPolicy> >
>
class NeighborSearch;
By choosing different components for each of these template classes, a very arbitrary neighbor searching object can be constructed.
SortPolicy policy class
The SortPolicy template parameter allows specification of how the NeighborSearch object will decide which points are to be searched for. The mlpack::neighbor::NearestNeighborSort class is a well-documented example. A custom SortPolicy class must implement the same methods which NearestNeighborSort does:
static size_t SortDistance(const arma::vec& list, double newDistance);
static bool IsBetter(const double value, const double ref);
template<typename TreeType>
static double BestNodeToNodeDistance(const TreeType* queryNode,
const TreeType* referenceNode);
template<typename TreeType>
static double BestPointToNodeDistance(const arma::vec& queryPoint,
const TreeType* referenceNode);
static const double WorstDistance();
static const double BestDistance();
The mlpack::neighbor::FurthestNeighborSort class is another implementation, which is used to create the 'AllkFN' typedef class, which finds the furthest neighbors, as opposed to the nearest neighbors.
MetricType policy class
The MetricType policy class allows the neighbor search to take place in any arbitrary metric space. The mlpack::metric::LMetric class is a good example implementation. A MetricType class must provide the following functions:
MetricType();
template<typename VecType>
double Evaluate(const VecType& a, const VecType& b);
Internally, the NeighborSearch class keeps an instantiated MetricType class (which can be given in the constructor). This is useful for a metric like the Mahalanobis distance (mlpack::metric::MahalanobisDistance), which must store state (the covariance matrix). Therefore, you can write a non-static MetricType class and use it seamlessly with NeighborSearch.
TreeType policy class
The NeighborSearch class also allows a custom tree to be used. The standard MLPACK tree, mlpack::tree::BinarySpaceTree, is also highly extensible in its own right, and its documentation should be consulted for more information. Currently, the NeighborSearch tree requires a tree which only has left and right children, and no points in nodes (only in leaves), but this support is planned to be extended.
A simple usage of the TreeType policy could be to use a different type of bound with the tree. For instance, you could use a ball bound instead of a rectangular bound:
NeighborSearch<
NearestNeighborSort,
tree::BinarySpaceTree<bound::BallBound<2>,
QueryStat<SortPolicy> >
> neighborSearch(dataset);
It is important to note that the NeighborSearch class requires use of the QueryStat tree statistic to function properly. Therefore, if you write a custom tree, be sure it can accept the QueryStat type. See the mlpack::tree::BinarySpaceTree documentation for more information on tree statistics.
Further documentation
For further documentation on the NeighborSearch class, consult the complete API documentation.


Download and unzip the contents of the archive to any convenient location. The package contains the following folders:
- <>[php]<> - Contains the jqScheduler and the driver files for the appropriate database.
- <>[themes]<> - Contains the themes shipped with the product. Since jqScheduler supports jQuery UI Themeroller, any theme compatible with jQuery UI ThemeRoller will work for jqScheduler as well. Therefore, the package contains just one theme ("Redmond"). You can download any additional themes directly from jQuery UI's ThemeRoller site available here:
<>http://jqueryui.com/themeroller/<>
In addition to the "Redmond" theme, there is one more file in the [themes] folder - ui.jqsheduler.css. This is the one and only Css file jqSceduler needs. Just add it after you add the reference to the "Redmond" theme in your PHP/HTML file containing jqGrid for PHP.
- <>[js]<> - The javascript files of jqScheduler (and the needed libraries). You need to include them in your PHP page.
The first file is "jquery.js" - this is the official jQuery library on which jqGrid is built upon.
The next one is the jqScheduler javascript code itself, located in "jquery.jqScheduler.min.js"
Before to create any files to run the jqScheduler, we need to create the database table that holds the information for the Scheduler.
The default table name is events and you should create it in your database where you plan to use the jqScheduler. The table definition for MqSql database is in directory php/backend/db_mysql.sql.
If the table can not be named events (or you have already such one) rename it in you way and then after creating the instance do .
$eventcal->table ="your_new_table_name";
See below
After this is done the final result you will have in an PHP page containing jqSceduler would be something similar to that:
<>
jqSheduler
......
.......
<>
Save the file as jqscheduler.php or any desired name in the root directory.
In the root directory you will find a file named jq-config.php. Open the file and enter the appropriate information for the connection to the database. Save the file and then create a file eventcal.php with the following content. Note that this example will use the database and tables provided with the demo.
<>
query("SET NAMES utf8");
$eventcal = new jqScheduler($conn);
$eventcal->table ="events";
$eventcal->setLocale('en_GB');
$eventcal->setUrl('eventcal.php');
$eventcal->setUser(1);
$eventcal->setUserNames(array('1'=>"Calender User 1",'2'=>"Calendar user 2") );
$eventcal->render();
?>
<>
Run the file jqscheduler.php from your web browser.

Hi Patrick,
welcome to the club of Gecode contributors. I just happened to read through
your checkin comments.
Please always keep the consistency level agrument, even though you only have
bnds consisten versions: this will making interfacing to Gecode much simpler
(think of a modelling language where one is allowed to annotate entire
expressions by conistency level). So, keep and ignore ;-)
Cheers

England
London
London is by far my favourite destination that I have visited in my life.
It has everything I could possibly want in a city: My favourite football team, Arsenal play there, it has endless tourist sites, an incredible transport system, a lovely culture and overall there is just a great atmosphere there.
Spain
Málaga
Benalmádena, Málaga was the most popular sun destination for my family when I was younger.
We went there nearly every year and I absolutely loved it. It has everything: beautiful beaches, delicious food, amazing water parks, gorgeous sunshine and lovely people.
Portugal
Algarve
I went to Albufeira in the Algarve for my 6th year holiday with my friends and I had one of the best weeks of my life there. The nightlife was absolutely amazing; perfect for young people and the people there are so friendly.
France
Paris
I have visited Paris twice in my life and both times it was an amazing experience. Everything is so beautiful: the food, the sights and the weather. I would love to go back again in the future.


#MediaQuery
MediaQuery
helps perform actions when CSS query is matched instead of polling the window width, when it's not so important to get exact width, only checking matching the query.
function onMatch(matches){
if(matches){
// do what you need when the mediaquery is matched
} else {
// do what you need when the media query is not matched
}
}
var mq = new MediaQuery({query:"max-width:760px"},onMatch,this);
//at any time you may check whether it matches the query:
mq.matches //true or false


This movie is made by 3 students that are studying at New York University Abu Dhabi. The whole movie was done in a combined total time of 30 minutes, with the filming and editing, all was done remotely. The idea presented is that of a morning routine of all three students where each student films a different part. This starts from waking up and turning the alarm off, some steps in between, all the way to turning on the laptop and joining a zoom class.

This week, we will be discussing web design as it relates to the user's ability to orient themselves in relation to a given website. "Orient" means, "does the user understand what this site is and does" and "can the use navigate within the site". Specifically we'll analyze harborfreight.com, a seller of a huge variety of discount tools making user navigation is significant element of the page's usability
The criteria we'll use to evaluate the navigatbility of harborfreight.com will be
- Is every page identifiable as belonging Harbor Freight's (HF) website?
- Does each page within HF's website identify itself?
- Does each page have an indicator of where the user is relative to the other pages within HF's website?
- Can a user perform a keyword search from every page?
Lets begin
Criterion 1: Is every page identfiable as a page within of HF.com?
"Identifiable as a page" means that each page has a large, clear identification that you are still accessing harborfreight's page and didnt accidentally relocate. With the ease with which a user can click around a website and weith the heightened fear of "online scams", users will look for verification that they are where they think they are. At the most basic level, this means "am I visiting harborfreight.com"
This is a screenshot from hf.com, we can see that there is a clear site ID, with the company logo, in the upper left section of the page. It is however, not at the very top. Its near the top, but not where a user would expect a site ID to be located.
As an added bonus, the site ID contains a tagline that allows the user to make accurate, snap judgements about the's purpose and content. In this case a seller of disconut tools.
Given the current COVID-19 pandemic, updated store hours information appears at the very top pushing the site ID down about 30 pixels. This is probably a temporary change, however even under normal conditions a utility bar and e-commerce shopping cart appear at a higher levle than site id. Generally speaking this probably does not affect usability, however design convention is that site ID is most prominently displayed at the top of the page. Overall this design element is good, but not ideal
Criterion 2: Is each page identified?
Page identification means, below Site ID, is there a title or indicator of the page within HF.com you are visiting. To evaluate this, we visited the sub-page for "electrical", accessible from HF.com's home page. When clicking the link for "electrical" tools, we are taken to the "electrical" page. What we find is that the page identification is clear and located in the upper left and below the Site ID, where a user would expect. Additionally, the page ID of "Electrical" matches the terminology that the user clicked form the home page, an added plus
Highlighting link from home page to sub-page
Overall, the design of hf.com page ID's conform to design convention and provide a good level of usability
Criterion 3: Can the user understand where they are within the sceme of the site?
Understanding where a user is within the scheme of a site is a critical navigational element. As a user navigates within a website, they click on many links. Adding design elements that let the user visualize how they got where they are allows them to understand the web enviornment and make better navigational choices.
HF.com has many categories and many trails for a user to follow...Home page > tool category > sub category > specific product would be a common path. HF.com uses breadcrumbs with links to past pages, separated by '>' symbols, all of which are conventional design elements. Also, the location of the breadcrumb trail is at the top of the page. This element allows the user to clearly understand their location within the scheme of the site and backtrack if needed.
Criterion 4: Can the user Search at any time?
A subset of users will not attempt to navigate a site on their own and instead prefer to use a search bar. Some users will attempt to navigate, then if unsuccessful, will use the search function.
HF.com has a search function on every page, allowing the user to search from wherever they may find themselves. This, in and of itself, is not sufficient as a design element. The quality of the search must also be high enough to let the user succeed in their navigation. I tested HF.com's search quality with 3 different products that we knew with certainty were offered on their site, each time succeeding in locating the intended product
Keyword entered (above) and results (below)
Summarizing, the search function of hf.com appears to be of high enough quality that a user can succeed in navigating the site by using it
Summary
Overall, HF.com is a well designed site with conventional design elements allowing the user to understand where they are, what theyre doing and confirm that theyre on the correct path to their goals.

CreateObjectDemo
program creates an object and assigns it to a variable:
Point originOne = new Point(23, 94); Rectangle rectOne = new Rectangle(originOne, 100, 200); Rectangle rectTwo = new Rectangle(50, 100);
Point
class,
and the second and third lines each create an
object of the
Rectangle
class.
Each of these statements has three parts (discussed in detail below):
type name;
You can also declare a reference variable on its own line. For example:
Point originOne;
originOne
like this, its value will be undetermined
until an object is actually created and assigned to it.
Simply declaring a reference variable does not create an object.
For that, you need to use the new
operator,
as described in the next section. You must assign an object to originOne
before you use it in your code. Otherwise, you will get a compiler error.
A variable in this state, which currently references no object,
can be illustrated as follows (the variable name, originOne
,
plus a reference pointing to nothing):
The new operator requires a single, postfix argument: a call to a constructor. The name of the constructor provides the name of the class to instantiate.
The new operator returns a reference to the object it created. This reference is usually assigned to a variable of the appropriate type, like:
Point originOne = new Point(23, 94);
int height = new Rectangle().height;
public class Point { public int x = 0; public int y = 0; //constructor public Point(int a, int b) { x = a; y = b; } }
Point originOne = new Point(23, 94);
public class Rectangle { public int width = 0; public int height = 0; public Point origin; // four constructors public Rectangle() { origin = new Point(0, 0); } public Rectangle(Point p) { origin = p; } public Rectangle(int w, int h) { origin = new Point(0, 0); width = w; height = h; } public Rectangle(Point p, int w, int h) { origin = p; width = w; height = h; } // a method for moving the rectangle public void move(int x, int y) { origin.x = x; origin.y = y; } // a method for computing the area of the rectangle public int getArea() { return width * height; } }
Rectangle rectOne = new Rectangle(originOne, 100, 200);
Rectangle
's constructors that
initializes origin
to originOne
.
Also, the constructor sets width
to 100 and
height
to 200.
Now there are two references to the same Point object—
an object can have multiple references to it, as shown in the next figure:
Rectangle
constructor that requires two
integer arguments, which provide the initial values for width
and height. If you inspect the code within the constructor,
you will see that it creates a new Point object whose x
and y values are initialized to 0:
Rectangle rectTwo = new Rectangle(50, 100);
Rectangle rect = new Rectangle();
Object
constructor if the class has no other parent.
If the parent has no constructor (Object
does have one), the compiler will reject the program.

Michelle Visage posts epic throwback to celebrate RuPaul's birthday
Michelle Visage has given fans an amazing glimpse to her decades-long friendship with RuPaul with an epic throwback.
The Strictly star wasn’t about to just let her bestie’s birthday pass her by, and so took the opportunity to share a cute moment of them from a cowboy hat.
In a photo dated around the 90s (we’re guessing because of that epic Ginger Spice-style red and blonde hairdo Michelle’s sporting), the pair are still beaming as big as ever.
She wrote next to the photo: ‘HAPPY BIRTHDAY to my ride or die. This world is a better place because of your love and wisdom. Every day I thank God for you.
‘Thank you for all that you have done, for all that you continue to do and for what’s to come. You are magical, Ru and I couldn’t possibly love you more.’

The pair have been pioneers of the LGBTQIA+ movements over the past 20 years together, bringing drag to the mainstream thanks to RuPaul’s Drag Race.
Hey, Ru’s not called Supermodel of the World for nothing!
Turning 59 today, the pair have been working harder than ever as they launch a celebrity version of the series, announcing a second UK series as well as a new All-Star and regular series.
Michelle even paid homage to her community with a performance to Vogue by Madonna on Strictly Come Dancing during the Blackpool special on Saturday night.
Letting her body ‘move to the music’, the star put on her fiercest poses while dressed in a French Revolution style dress alongside Giovanni Pernice.
Results are due to air tonight, with all seven remaining contestants relying on votes in order to keep themselves in the race.
RuPaul’s Drag Race UK continues Thursday at 8pm on BBC iPlayer.

Most of the times, we want to extract nested module in architecture; while some modules support indexing (Sequential), some don't. This function enables you to access nested modules in a numpy-like indexing. When coupled with arch_summary
, we can effortlessly explore the pytorch models.
from torchvision.models import shufflenet_v2_x1_0, resnet50
arch_summary
can handle named as well as simple Sequential modules with different behavior. Indices could be used to quickly navigate the architecture, module names are also introduced in summary if available. xresnet50
is the architecture defined in fastai2
and is extending Sequential
arch_summary(xresnet50)
get_module
could be used to extract a specific module nested deep within hierarchy.
get_module(xresnet50,[4,0])
And if you really want to go deeper, you may set verbose=True
and arch_summary
will go 2 depth down. For the simplicity, I'm keeping it to the depth of 2, since you can always have a detailed summary using fastai2
's patched summary method on module
arch_summary(xresnet50,verbose=True)
Now let's quickly review a named_module architecture and how arch_summary
handles that information
arch_summary(shufflenet_v2_x1_0)
Refer arch_explore for more examples


The VIPS file formatFile format — The VIPS file format |
VIPS has a simple, native file format. It's very fast, there is no image
size limit, and it supports
arbitrary metadata. Although few other programs can read these images
(though recent versions of ImageMagick do have basic support for
.vips
format), it can be useful as an intermediate format for command-line
processing. For example:
$ vips invert input.tif t.v $ vips gamma t.v output.tif
is faster than using .tif
for the temporary intermediate
image. This section documents the VIPS file format.
VIPS comes with a command-line program called vipsedit which is useful for destructively changing fields in a vips image. The vipsheader program can be used to extract any metadata.
VIPS files come in three parts. First, there is a 64-byte header, containing an identifying magic number and a set of very basic fields, such as image width in pixels. Next, the image data is stored as a set of band-interleaved scanlines, from the top of the image to the bottom. Finally, after the pixel data comes an optional block of XML containing any extra metadata, such as an ICC profile or the EXIF data.
The fields in the VIPS header are always stored least-significant byte first (Intel ordering). Only the most basic information about the image is in the header: most metadata is stored in the XML extension block after the pixel data.
If the first four bytes of the file are in order 08 f2 a6 b6, the image data (see the next section) is stored in Intel byte order (LSB first) and will need to be swapped if read on a SPARC-style machine (MSB first). If the magic number is b6 a6 f2 08, the image data is in SPARC order and will need to swapped if read on an Intel-style machine. libvips does this swapping automatically.
Table 2. The VIPS header
| Bytes | Type | VIPS name | Meaning |
|---|---|---|---|
| 0 -- 3 | VIPS magic number: 08 f2 a6 b6, or b6 a6 f2 08 | ||
| 4 -- 7 | gint |
width |

xoffset |
Horizontal offset of origin, in pixels |
| 52 -- 55 | gint |
yoffset |
Vertical offset of origin, in pixels |
| 56 -- 63 | Unused |
If coding
is set to VIPS_CODING_NONE, pixels are stored in
native C format, that is, the native format of the
machine that wrote the data. If you open a big-endian image on a
little-endian machine, VIPS will automatically byte-swap for you.
VIPS has 10 band formats, see VipsBandFormat.
Image data is stored as a simple list of scanlines, from the top of the
image to the bottom. Pixels are band-interleaved, so RGBRGBRGBRGB,
for example. There is no padding at the end of scanlines.
If coding
is set to VIPS_CODING_LABQ, each pixel is four
bytes, with 10 bits for L* and 11 bits for each of a* and b*. These
32 bits are packed into 4 bytes, with the most significant 8 bits of each
value in the first 3 bytes, and the left-over bits packed into the final
byte as 2:3:3.
If coding
is set to VIPS_CODING_RAD, each pixel is
RGB or XYZ float, with 8 bits of mantissa
and then 8 bits of exponent, shared between the three channels. This
coding style is used by the Radiance family of programs (and the HDR
format) commonly used for HDR imaging.
Other values of coding
can set other coding styles. Use
VIPS_IMAGE_SIZEOF_IMAGE()
to calculate the size of the image data
section.
Following the image data is a chunk of XML holding a simple list of
name-value pairs. Binary data is encoded with base64. Use
vips_image_set()
and friends to set and get image metadata.
You can use vipsheader -f getext some_file.v to get the XML from a VIPS image, and vipsedit --setext some_file.v < file.xml to replace the XML.

TXMPFiles
provides the API for the Adobe XMP Toolkit's File Handler component. This provides convenient access to the main, or document level, XMP for a file. The general model is to open a file, read and write the metadata, then close the file. While open, portions of the file might be maintained in RAM data structures. Memory usage can vary considerably depending on file format and access options. The file may be opened for read-only or read-write access, with typical exclusion for both modes.
Errors result in the throw of an XMPError
exception.
The template is instantiated with a string object class. This allows a clean implementation that provides two major benefits: output string storage is fully owned by the client and access is fully thread safe. The template parameter, class tStringObj
, is described in the XMP.hpp umbrella header.
To use TXMPFiles define TXMP_STRING_TYPE and XMP_INCLUDE_XMPFILES, then include the XMP.hpp umbrella header:
#define TXMP_STRING_TYPE std::string #define XMP_INCLUDE_XMPFILES 1 #include "XMP.hpp"
| static bool TXMPFiles< tStringObj >::GetFormatInfo | ( | XMP_FileFormat | format, | |
| XMP_OptionBits * | handlerFlags = 0 | |||
| ) | [static] |
Determine the supported features for a given file format.
The supported features can vary quite a bit among file formats, depending on both the general capabilities of the format and the implementation of the handler for that format.
| format | The format whose support flags are desired. | |
| handlerFlags | A set of option bits showing the support for this format: |
If kXMPFiles_ReturnsRawPacket is set, the returned packet information might have an offset of -1 to indicate an unknown offset. While all file handlers should be able to return the raw packet, some might not know the offset of the packet within the file. This is typical in cases where external libraries are used. These cases might not even allow return of the raw packet.
| bool TXMPFiles< tStringObj >::OpenFile | ( | XMP_StringPtr | filePath, | |
| XMP_FileFormat | format = kXMP_UnknownFile , |
|||
| XMP_OptionBits | openFlags = 0 | |||
| ) |
Open a file for metadata access.
Opens a file for the requested forms of metadata access. Opening the file at a minimum causes the raw XMP packet to be read from the file. If the file handler supports legacy metadata reconciliation then legacy metadata will also be read, unless kXMPFiles_OpenOnlyXMP is passed. If the file handler supports native thumbnails and kXMPFiles_OpenCacheTNail is passed then the native thumbnail will also be cached.
If the file is opened for read-only access (passing kXMPFiles_OpenForRead), then the disk file itself will be closed after reading the data from it. The XMPFiles object will not be "closed" though, it is still necessary to call CloseFile when finished using it. Other methods (GetXMP, etc.) can only be used between the OpenFile and CloseFile calls. The XMPFiles destructor will not call CloseFile, any pending updates will be lost.
If the file is opened for update (passing kXMPFiles_OpenForUpdate), then the disk file remains open until CloseFile is called. The disk file is only updated once, when Close file is called, no matter how many calls are made to PutXMP.
Ideally the XMP is not parsed and legacy reconciliation is not performed until GetXMP is called. This is not guaranteed though, specific file handlers might do earlier parsing of the XMP. This delayed parsing and the early disk file close for read-only access are optimizations to help clients implementing file browsers. They can access the file briefly and possibly display a thumbnail, then postpone more expensive XMP processing until later.
| filePath | The UTF-8 path for the file, appropriate for the local OS. Overloads are declared to pass the path as either a "const char *" or a string object. | |
| format | The format of the file. If the format is unknown pass kXMP_UnknownFile and the format will be determined from the file content. The first handler to check will be guessed from the file's extension. Passing any other format value is generally just a hint about what file handler to try first (instead of the one based on the extension). If the kXMPFiles_OpenStrictly is set, then any format other than kXMP_UnknownFile requires that the file actually be that format, an exception is thrown if not. | |
| openFlags | A set of option bits describing the desired access. By default (zero) the file is opened for read-only access and the format handler decides on the level of reconciliation that will be performed. By default a best effort will be made to locate the correct XMP and to reconcile XMP with other forms (if reconciliation is done). The option kXMPFiles_OpenStrictly may be used to force more strict rules, resulting is exceptions for errors. The definition of strictness is specific to each handler, there may be no difference. |
| void TXMPFiles< tStringObj >::CloseFile | ( | XMP_OptionBits | closeFlags = 0 |
) |
Close an opened file.
Performs any necessary output to the file and closes it. Files that are opened for update are written to only when closing.
| closeFlags | A set of bit flags for optional closing actions. |
| bool TXMPFiles< tStringObj >::GetFileInfo | ( | tStringObj * | filePath = 0 , |
|
| XMP_OptionBits * | openFlags = 0 , |
|||
| XMP_FileFormat * | format = 0 , |
|||
| XMP_OptionBits * | handlerFlags = 0 | |||
| ) |
Get basic information about an opened file.
| filePath | If not null, returns the path passed to OpenFile. | |
| openFlags | If not null, returns the flags passed to OpenFile. | |
| format | If not null, returns the format of the file. | |
| handlerFlags | If not null, returns the handler's capability flags. |
| void TXMPFiles< tStringObj >::SetAbortProc | ( | XMP_AbortProc | abortProc, | |
| void * | abortArg | |||
| ) |
Set the callback function used to check for a user signaled abort.
| abortProc | The callback function used to check for a user signaled abort. It will be called periodically to allow an abort of time consuming operations. The abort results in an exception being thrown. The callback function should return true to signal an abort. | |
| abortArg | An argument passed to the callback function. |
| bool TXMPFiles< tStringObj >::GetXMP | ( | SXMPMeta * | xmpObj = 0 , |
|
| tStringObj * | xmpPacket = 0 , |
|||
| XMP_PacketInfo * | packetInfo = 0 | |||
| ) |
Obtain the XMP.
GetXMP
is used to obtain the parsed XMP, and/or the raw XMP packet, and/or information about the raw XMP packet. If all parameters are null it simply tells if XMP is present or not. The options provided when the file was opened determine if reconciliation is done with other forms of metadata.
| xmpObj | If not null, returns the parsed XMP. | |
| xmpPacket | If not null, returns the raw XMP packet as stored in the file. The encoding of the packet is given in the packetInfo. The string will be empty if the low level file handler does not provide the raw packet. | |
| packetInfo | If not null, returns the location and form of the raw XMP in the file. The charForm and writeable flag reflect the raw XMP in the file. The parsed XMP property values are always UTF-8. The writeable flag is taken from the packet trailer, it is only relevant for "format ignorant" writing. |
PutXMP
unless the file is also written.
Some file handlers might not return location or contents of the raw packet string. Check the kXMPFiles_ReturnsRawPacket
bit returned by GetFormatInfo if you depend on this. If the low level file handler does not provide the raw packet location then the offset and length will both be 0, the charForm will be UTF-8, and the writeable flag will be false.
| bool TXMPFiles< tStringObj >::GetThumbnail | ( | XMP_ThumbnailInfo * | tnailInfo | ) |
Obtain the native thumbnail.
GetThumbnail
is used to obtain native thumbnail information, if the associated file handler supports that and the thumbnail was cached by OpenFile. This requires that kXMPFiles_OpenCacheTNail be passed to OpenFile. The tnailInfo output pointer can be null, in which case GetThumbnail will simply tell if a recognized native thumbnail is present.
| tnailInfo | If not null, returns information about a recognized native thumbnail, and some related information about the primary image if appropriate. |
| void TXMPFiles< tStringObj >::PutXMP | ( | const SXMPMeta & | xmpObj | ) |
Update the XMP.
PutXMP
supplies new XMP for the file. However, the file is not actully written until closed. The options provided when the file was opened determine if reconciliation is done with other forms of metadata. Overloads are provided to pass the XMP as an XMP object, a string object, or a "const char *" plus length.
| bool TXMPFiles< tStringObj >::CanPutXMP | ( | const SXMPMeta & | xmpObj | ) |
Determine if the XMP can be updated.
CanPutXMP
determines if the XMP can (probably) be updated. The provided XMP is only used to obtain the length of the serialized packet. The new XMP is not kept, calling this will not cause the file to be written when closed. Overloads are provided to pass the XMP as an XMP object, a string object, or a "const char *" plus length. This is implemented roughly as:
bool CanPutXMP ( XMP_StringPtr xmpPacket ) { XMP_FileFormat format; this->GetFileInfo ( 0, &format, 0 ); XMP_OptionBits formatFlags; GetFormatInfo ( format, &formatFlags ); if ( (formatFlags & kXMPFiles_CanInjectXMP) && (formatFlags & kXMPFiles_CanExpand) ) return true; XMP_PacketInfo packetInfo; bool hasXMP = this->GetXMP ( 0, 0, &packetInfo ); if ( ! hasXMP ) { if ( formatFlags & kXMPFiles_CanInjectXMP ) return true; } else { if ( (formatFlags & kXMPFiles_CanExpand) || (packetInfo.length >= strlen(xmpPacket)) ) return true; } return false; }
