dgw::txmixins - implementations of extensions for the text widget which can be added dynamically using chaining of commands at widget creation or using the dgw::txmixin command after widget creation.
package require Tk
package require snit
package require dgw::txmixins
::dgw::txmixin pathName widgetAdaptor ?options?
::dgw::txfold [tk::text pathName ?options?] ?options?
set txt [tk::text pathName ?options?]
dgw::txmixin $txt dgw::txfold ?options?
The package dgw::txmixins implements several snit::widgetadaptors which extend the standard tk::text widget with different functionalities. Different adaptors can be chained together to add the required functionalities. Furthermore at any later time point using the dgw::txmixin command other adaptors can be installed on the widget.
dgw::txmixin pathName mixinWidget ?-option value ...?
Adds the properties and methods of a snit::widgetadaptor specified with mixinWidget to the exising widget created before with the given pathName and configures the widget using the given options.
Example:
# demo: mixin # standard text widget set text [tk::text .txt] pack $text -side top -fill both -expand true dgw::txmixin $text dgw::txfold # fill the widget $text insert end "\n## Hint\n\nPress F2 or F3 and see what happend!" for {set i 1} {$i < 4} {incr i} { $text insert end "## Header $i\n\n" $text insert end [dgw::lispum 3] }
dgw::txlipsum dgw::txlipsum n
Returns n paragraphs of simple lipsum text.
Example:
# demo: txlipsum tk::text .txt .txt insert end "[dgw::txlipsum 5]" .txt configure -borderwidth 10 -relief flat pack .txt -side top -fill both -expand yes -padx 5 -pady 5
dgw::txautorep [tk::text pathName] ?-option value ...?
Creates and configures the dgw::txautorep widget using the Tk window id pathName and the given options. All options are delegated to the standard text widget. Based on code in the Wiki page https://wiki.tcl-lang.org/page/autoreplace started by Richard Suchenwirth in 2008.
The following option is available:
- -automap list - list of abbreviations and their replacement, the abbreviations must end with a closing parenthesis such as [list DG) {Detlef Groth}].
 pack .txt -side top -fill both -expand yes
TODO: Take abbreviations from file
dgw::txblocksel [tk::text pathName] ?-option value ...?
Creates and configures the dgw::txblocksel widget using the Tk window id pathName and the given options. The text widget supports the block selection of text using The Control-key together with left mouse down and movement for selecting the text.
So the steps are:
The widget adaptor code is just an adaption from the Wiki code written by Martin Eder here: Simple Block Selection for Text Widget.
The widget adaptor currently has no options and public methods which should be used. The code is however a good example on how to port namespace based widget code into a snit widgetadaptor using snit procedures only.
Example:
# demo: txblocksel dgw::txblocksel [tk::text .txt -undo true] .txt insert end "\nHint:\n\n* Press Ctrl-Button-1 and then, by holding move the mouse\n" .txt insert end "to the bottom right.\n* For copy and paste use Control-c and Control-v." .txt tag configure hint -foreground #1166ff .txt tag add hint 1.0 6.end .txt insert end "\n\nBlock selection!\n\n" foreach col [list A B C] { .txt insert end "# Header $col\n\nSome text\n\n" .txt insert end [dgw::txlipsum 2] .txt insert end "\n\n" } .txt configure -borderwidth 10 -relief flat pack .txt -side top -fill both -expand yes -padx 5 -pady 5
dgw::txfileproc [tk::text pathName] ?-option value ...?
Creates and configures the dgw::txfileproc widget using the Tk window id pathName and the given options. The text widget supports the typical file actions, so fileNew, fileOpen, fileSave, fileSaveAs and fileExit with checks for file modifications. It comes with a set of default bindings which can be disabled quite easily, see below for an example.
The following options are available:
- -openkey sequence - the key sequence to open the file open dialog, can be inactivated by supplying an empty string, default: Control-o
- -savekey sequence - the key sequence to save the current file or the file save as dialog if there is currently no file opened, can be inactivated by supplying an empty string, default: Control-s
- -newkey sequence - the key sequence to create an empty new file with checking for modified text, can be inactivated by supplying an empty string, default: Control-n
- -quitkey sequence - the key sequence to close the application with checking for modified text, can be inactivated by supplying an empty string, default: "Control-q"
- -filecallback proc - a callback to be executed if a file action like fileSave etc is performed, the Tcl procedure must take two arguments, first the action, second the filename, see below for an example, default: empty string, so no callback.
- -filetypes list - the filetypes to be used for the file dialogs, defaults to Text (*.txt), Tcl (*.tcl, *.tm), Markdown (*.md, *.rmd) and any (*.*) files.
- -initdir directory - the initial starting dir for the first file dialog, subsequent file dialogs will use the directory for the last opened files.
The following public methods are available:
- getFile - get the currently loaded file, if no file is loaded yet returns *new*
- fileNew - creates a new empty file named *new*
- fileSave - saves the currently opened file, if it is a new file, fileSaveAs will be called
- fileSaveAs - calls the file save dialog to save the current text in a new file
- fileOpen ?filename? - will open the given filename or if no filename is given opens the file dialog to select a file.
- fileExit - checks for text modifications and will then quit the application
- fileRecent - returns the last recent opened files with the last file as first element
The following events are implemented by this widget adaptor:
- <<FileChanged>> if a new file is opened or the save-as option is called.
- <<FileSaved>> if the current file is saved
Example:
# demo: txfileproc dgw::txfileproc [tk::text .txt -undo true] -openkey "" ;# disable Control-o rebind it below .txt insert end "\nHint\n\nPress ctrl-o, control-n, control-s\n and see the" .txt insert end "standard file dialogs!\n\n" foreach col [list A B C] { .txt insert end "# Header $col\n\nSome text\n\n" .txt insert end [dgw::txlipsum 2] .txt insert end "\n\n" } .txt configure -borderwidth 10 -relief flat .txt configure -filecallback callback pack .txt -side top -fill both -expand yes -padx 5 -pady 5 pack [label .label -text ""] -side top -fill x -expand false -padx 5 -pady 5 bind .txt <Enter> { focus -force .txt } bind .txt <Control-k><Control-x> [list .txt fileExit] bind .txt <Control-k><Control-o> [list .txt fileOpen] dgw::txmixin .txt dgw::txpopup ;# right click popup proc callback {type filename} { .label configure -text "Done: $type with [file tail $filename]" puts [.txt fileRecent] } proc eventMessage {w} { puts "currentFile [$w getFile]" } bind .txt <<FileChanged>> [list eventMessage %W]
dgw::txfold [tk::text pathName] ?-option value ...?
Creates and configures the dgw::txfold widget using the Tk window id pathName and the given options. The widgets supports text folding based on linestart regular expressions usually which allows fast navigation of larger documents by hiding and showing larger chunks of text within the folding marks.
The following options are available:
- -foldkey sequence - the key sequence fold or unfold regions where the insert cursor is within, default: F2
- -foldallkey sequence - the key sequence to fold/unfold the complete text, default: F3
- -foldstart regex - the start folding marker, default is Markdown header folding using the '#' at the beginning, default: "^#"
- -foldend regex - the end fold marker, where the folding ends, if the end marker is the same as the start marker folding is ended in the line before the end line, otherwise on the end line, default: "^#"
The following widget tags are created and can be modified at runtime:
- fold - the folding line which remains visible, usually the background should be configured only, default is
#ffbbaa
a light salmon like color- folded - the hidden (-elide true) part which is invisible, usually not required to change it, as it is hidden
Example:
# demo: txfold dgw::txfold [tk::text .txt] foreach col [list A B C] { .txt insert end "# Header $col\n\nSome text\n\n" } .txt insert end "Place the cursor on the header lines and press F2\n" .txt insert end "or press F3 to fold or unfold the complete text.\n" .txt tag configure fold -background #cceeff .txt configure -borderwidth 10 -relief flat pack .txt -side top -fill both -expand yes # next line would fold by double click (although I like F2 more ...) # .txt configure -foldkey Double-1 bind .txt <Enter> { focus -force .txt }
TODO: add Tcl fold example
dgw::txhighlight [tk::text pathName] ?-option value ...?
Creates and configures the dgw::txhighlight widget using the Tk window id pathName and the given options. The widgets supports text highlighting for different file types by providing tag names and regular expressions.
The following options are available:
- -highlightcommand proc - a possible command to be used for hilighting, default: empty string, i.e. none
- -highlights list - a nested list with highlights first element file type, second tag, third regular expression
The following widget tags are created and can be used for highlighting and can be as well as well configured by the user to change the appearance
- header, comment, highlight, keyword, operator, string, package, class, method, proc
Example:
# demo: txhighlight
package require dgw::txmixins
text .top -borderwidth 5 -relief flat -font "Helvetica 14"
dgw::txmixin .top dgw::txhighlight
.top configure -highlights {{md header ^#.+}
{md comment ^>.+}
{md keyword _{1,2}[^_]+_{1,2}}
{md string {"[^"]+"}}}
pack .top -side top -fill both -expand true ;#"
# TODO: txfileproc .top configure -filetypes {{Markdown Files} {.md}}
# configure for Markdown highlight
.top configure -highlights {{md header ^#.+}
{md comment ^>.+}
{md keyword _{1,2}[^_]+_{1,2}}
{md string {"[^"]+"}}}
.top configure -mode md
# create sample Markdown text and insert it
.top insert end "# Header example\n"
.top insert end "_keyword_ example\n"
.top insert end "Some not highlighted text\n"
.top insert end "> some markdown quote text\n"
.top insert end "## Subheader\n"
.top insert end "Some more standard text with two \"strings\" which are \"inside!\""
.top insert end "\n\n## Tcl\n\nTcl be with you!\n\n## EOF\n\nThe End\n"
.top insert 3.0 "\nSome text\nSome more text"

# switch to SQL highlight which is embedded per default
.top delete 1.0 end
.top configure -mode sql
.top insert end "select * from temp limit 10;\n -- a comment in SQL\n drop table temp;\n"
dgw::txindent [tk::text pathName] ?-option value ...?
Creates and configures the dgw::txindent widget using the Tk window id pathName and the given options. All options are delegated to the standard text widget. The widget indents every new line based on the initial indention of the previous line. Based on code in the Wiki page https://wiki.tcl-lang.org/page/auto-indent started by Richard Suchenwirth.
Example:
# demo: txindent dgw::txindent [tk::text .txt] foreach col [list A B C] { .txt insert end "# Header $col\n\nSome text\n\n" } .txt insert end " * item 1\n * item 2 (press return here)" pack .txt -side top -fill both -expand yes
dgw::txpopup [tk::text pathName] ?-option value ...?
Creates and configures the dgw::txpopup widget using the Tk window id pathName and the given options. The text widget supports the typical right click popup operations for the text widget like undo/redo, copy, paste, delete etc. It comes with a set of default bindings which can be disabled quite easily, see below for an example.
The following options are available:
- -redokey sequence - the key sequence to redo an operation, default: Control-y
- -popupkey sequence - the key sequence to open the popup, usually right mouse click, so default: Button-3
- -toolcommand procname - the name of a procedure which is called when the tool command is exectued, default emtpy string, none
The following public method is available:
- menu - show the popup menu, usually the right mouse click, but the user can create additional popup keys.
Example:
# demo: txpopup dgw::txpopup [tk::text .txt -undo true] .txt insert end "\nHint\n\nPress right mouse click\n and see the" .txt insert end "popup menu with context dependent active or inactive entries!\n\n" foreach col [list A B C] { .txt insert end "# Header $col\n\nSome text\n\n" .txt insert end [dgw::txlipsum 2] .txt insert end "\n\n" } dgw::txmixin .txt dgw::txblocksel ;# just another mixin .txt configure -borderwidth 10 -relief flat pack .txt -side top -fill both -expand yes -padx 5 -pady 5 bind .txt <Enter> { focus -force .txt }
dgw::txrotext [tk::text pathName] ?-option value ...?
Creates and configures the dgw::txrotext widget using the Tk window id pathName and the given options. All options are delegated to the standard text widget. This creates a readonly text widget. Based on code from the snitfaq by William H. Duquette.
Methods: instead of insert and delete you have to use the methods ins and del
Example:
# demo: txrotext dgw::txrotext [tk::text .txt] foreach col [list A B C] { .txt ins end "# Header $col\n\nSome text\n\n" } pack .txt -side top -fill both -expand yes
EXAMPLE
In the examples below we create a foldable text widget which can fold Markdown headers. Just press the button F2 and F3 to fold or unfold regions or the complete text. Thereafter a demonstration on how to use the dgw::txmixin command which simplifies the addition of new behaviors to our tk::text in a stepwise manner. The latter approach is as well nice to extend existing widgets in a more controlled manner avoiding restarts of applications during developing the widget.
package require dgw::txmixins
# standard text widget
set f [ttk::frame .f]
set text [tk::text .f.txt -borderwidth 5 -relief flat]
pack $text -side left -fill both -expand true
dgw::txmixin $text dgw::txfold
# fill the widget
for {set i 0} {$i < 5} {incr i} {
$text insert end "## Header $i\n\n"
for {set j 0} {$j < 2} {incr j} {
$text insert end "Lorem ipsum dolor sit amet, consetetur sadipscing elitr,\n"
$text insert end "sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat,\n"
$text insert end "sed diam voluptua. \nAt vero eos et accusam et justo duo dolores et ea rebum.\n"
$text insert end "Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.\n\n"
}
}
set tcltxt [tk::text .f.tcl -borderwidth 5 -relief flat]
dgw::txmixin $tcltxt dgw::txfold -foldstart "^\[A-Za-z\].+\{" -foldend "^\}"
$tcltxt tag configure fold -background #aaccff
$tcltxt insert end "package require Tk\nproc test {} {\n puts Hi\n}\n\nsnit::widget wid {\n\n}\n"
pack $tcltxt -side left -fill both -expand true
pack $f -side top -fill both -expand yes
set f2 [ttk::frame .f2]
dgw::txrotext [tk::text $f2.rotxt]
foreach col [list A B C] {
$f2.rotxt ins end "# Header $col\n\nSome text\n\n"
}
pack $f2.rotxt -side left -fill both -expand yes
dgw::txindent [tk::text $f2.intxt]
dgw::txmixin $f2.intxt dgw::txfold
$f2.intxt insert end "# Header 1\n\n* item\n * subitem 1\n * subitem2"
$f2.intxt insert end "# Header 2\n\n* item\n * subitem 1\n * subitem2"
$f2.intxt insert 5.0 "\n" ; $f2.intxt tag add line 5.0 6.0 ;
$f2.intxt tag configure line -background black -font "Arial 1"
pack $f2.intxt -side left -fill both -expand yes
pack $f2 -side top -fill both -expand yes
Installation is easy you can install and use the dgw::txmixins package if you have a working install of:
For installation you copy the complete dgw folder into a path of your auto_path list of Tcl or you append the auto_path list with the parent dir of the dgw directory. Alternatively you can install the package as a Tcl module by creating a file dgw/txmixins-0.2.0.tm in your Tcl module path.
Only if you you like to extract the HTML documentation and run the examples, you need the complete dgw package and for the HTML generation the tcllib Markdown package.
Example code for this package in the EXAMPLE section can be executed, if you have the complete dgw package installed, by running this file using the following command line:
$ wish txmixins.tcl --demo
Specific code examples outside of the EXAMPLE section can be executed using the string after the demo: prefix string in the code block for the individual code adaptors such as:
$ wish txmixins.tcl --demo txfold
The example code used for the demo in the EXAMPLE section can be seen in the terminal by using the following command line:
$ tclsh txmixins.tcl --code
The script contains embedded the documentation in Markdown format. If you have the complete dgw package installed you can extract the Markdown documentation. For this you should use the following command line:
$ tclsh txmixins.tcl --markdown
This will extract the embedded manual pages in standard Markdown format. You can as well use this markdown output directly to create html pages for the documentation by using the --html flag.
$ tclsh txmixins.tcl --html
If the tcllib Markdown package is installed, this will directly create a HTML page txmixins.html
which contains the formatted documentation.
Github-Markdown can be extracted by using the --man switch:
$ tclsh txmixins.tcl --man
The output of this command can be used to feed a Markdown processor for conversion into a html, docx or pdf document. If you have pandoc installed for instance, you could execute the following commands:
tclsh ../txmixins.tcl --man > txmixins.md
pandoc -i txmixins.md -s -o txmixins.html
pandoc -i txmixins.md -s -o txmixins.tex
pdflatex txmixins.tex

The super simple way to use Google Charts with remote data - all wrapped up in an easy to use jQuery plugin.
Simply include the JavaScript file after including jQuery and the Google Charts library.
<script src="jQuery.min.js"></script> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> <script type="text/javascript"> google.charts.load('current', {packages: ['corechart']}); </script> <script src="jquery.ajax-chart.js"></script>
jQuery's normal on load event can sometimes fire before Google Charts is ready. To prevent this, use the $.achart(...)
function.
$.achart(function() { //do chart initialization n stuff });
You should create a server-side script that returns a JSON object whose 'data'
key holds a valid Google Charts DataTable JSON object. See the Google Charts Documentation for the exact structure of the DataTable object. Here's an example of the JSON returned from a server-side script:
{"data": { "cols": [ { "label": "Dessert", "id": "dessert", "type": "string" }, { "label": "Count", "id": "count", "type": "number" } ], "rows": [ { "c": [ {"v": "Cake"}, {"v": 19} ] }, { "c": [ {"v": "Pie"}, {"v": 16} ] } ] }}
Feel free to add any extra data you want to the structure returned by your script. As long as the 'data'
key has a valid DataTable structure, you're good!
Call methods like this: $(containerSelector).achart(methodName, methodParameters);
Available methods are 'init'
, 'update'
, 'load'
, 'reload'
, 'draw'
, 'image'
, 'chart'
, 'wrapper'
, and 'verify'
.
Initializes an Ajax Chart.
$(...).achart('init', type, opts);
$('#my-container').achart('init', 'BarChart', { height: 250 });
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| type | String | 'PieChart' |
The type of chart to use. See the Google Charts Documentation for more information. | |
| opts | Object | {} |
The chart options to use. Available options are based on the chart type. See the Google Charts Documentation for more information. |
Let's initialize a donut chart!
$('#my-container').achart('init', 'PieChart', { pieHole: 0.4 });
Updates an Ajax Chart. Draws the chart only if the 'load'
method has already been called.
$(...).achart('update', opts);
$('#my-container').achart('update', { height: 250 });
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| opts | Object | {} |
The chart options to use. Available options are based on the chart type. See the Google Charts Documentation for more information. |
We can use this method to change our chart's appearance on the fly. In the below example, we use a button to make the 3 slices of our pie chart red. (Pretty useful, right?)
$('#red-mode-btn').on('click', function() { $('#my-container').achart('update', { colors: [ 'red', 'red', 'red' ] }); });
Loads the data for an Ajax Chart using an ajax call. Draws the chart when the response is received.
$(...).achart('load', ajax, expect);
$('#my-container').achart('load', { url: 'my-script.cgi' });
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| ajax | Object | Yes | {} |
Options to use for the ajax call. See the jQuery Documentation for more information. Please note that that the 'load' method forces { dataType: 'json' } . |
| expect | String | 'data' |
The key that will hold the new chart data in the JSON object returned by the server. |
The jqXHR object created by the ajax call. You can use it to add listeners to the request, as shown in the next example.
Here we leverage the jqXHR object returned by the 'load'
method to add a callback in case our ajax call fails:
$('#my-container').achart('load', { url: 'my-script.cgi' }).fail(function(xhr, status, error) { alert('Oh snap! There was an error!'); });
Loads the data for an Ajax Chart using an ajax call, but with the same ajax options and expected key as the last call of the 'load'
or 'reload'
method. Draws the chart when the response is received.
$(...).achart('reload', ajax, expect);
$('#my-container').achart('reload');
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| ajax | Object | Options to change from the last ajax call. See the jQuery Documentation for more information. Please note that that the 'load' method forces { dataType: 'json' } . |
||
| expect | String | The key that will hold the new chart data in the JSON object returned by the server. If this is left out, this will be the same as the last one that was passed. |
The jqXHR object created by the ajax call. You can use it to add listeners to the request, as shown in the next example.
In this example we will see how you can use the 'reload'
function to implement a "Refresh" button.
$('#my-refresh-btn').on('click', function() { $('#my-container').achart('reload'); });
The same idea can be expanded to create a simple filter interface, as shown here:
$('#current-year-dropdown').on('change', function() { var selectedYear = $(this).val(); $('#my-container').achart('reload', { data: { year: selectedYear } }); });
In the above code, we do an ajax request for the chart data every time our dropdown menu is changed. We pass in the selected year as a parameter so our server-side script knows which year's records it should select.
Use this method to get an image URI of the chart. Useful for exporting.
$(...).achart('image');
$('#my-container').achart('image');
The chart as an image URI.
In this example we will use the 'image'
method to make an "Export as Image" button for our chart.
$('#my-button').on('click', function() { //for modern browsers window.open($('#my-chart').achart('image')); //for IE window.open('', '_blank').document.write('<img src="' + $('#my-chart').achart('image') + '" />'); });
This method is used to get or set the chart's current selection. This works by interfacing with the Google Charts Library's .getSelection() and .setSelection() chart methods.
$(...).achart('select', selection);
$('#my-container').achart('select', [{ row: 1, column: null }]);
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| selection | String | A selection to apply to the chart. This is an array with the form: [ { row: ROWNUMBER, column: COLNUMBER }, ... ] . |
The current chart selection. If a new selection was passed, returns that selection.
Draws the chart. You usually won't have to call this method explicitly, because it's called automatically by the following Ajax Chart methods: 'update'
(if the chart has data), 'load'
(when the response is received), and 'reload'
(when the response is received).
$(...).achart('draw');
$('#my-container').achart('draw');
This method returns the Google Charts Chart object that Ajax Chart uses behind the scenes. See the documentation for more information. This method is useful for those times when you need access to the underlying Google Charts technology.
$(...).achart('chart');
$('#my-container').achart('chart');
The Chart object.
This method returns the Google Charts ChartWrapper object that Ajax Chart uses behind the scenes. See the documentation for more information. This method is useful for those times when you need access to the underlying Google Charts technology.
$(...).achart('wrapper');
$('#my-container').achart('wrapper');
The ChartWrapper object.
Checks if the selected element has been intialized as an ajax chart. Returns true
if it was and false
otherwise.
$(...).achart('verify');
$('#my-container').achart('verify');
A boolean indicating whether or not the element is an ajax chart.
The Ajax Chart plugin also features an interface for the Google Charts Library's Events. See their documentation for more information. Simply use jQuery's .on()
function to bind the underlying Google Chart's 'select'
, 'ready'
, and 'error'
events using the 'achart.select'
, 'achart.ready'
, and 'achart.error'
event names, respectively. Note that the 'achart.select'
event's callback function will receive one extra parameter, which is an object specifying the current selection with the form: { row: ROWNUMBER, column: COLNUMBER }
.
Here's an example of using the 'select'
event.
$('#my-container').on('achart.select', function(event, selection) { console.log(selection); });

Default properties and methods of the req object.
This object is automatically instantiated as the req property
of the global object (or global.req) and there is no constructor
to instantiate further instances.
The req object is a host object representing the request that is currently handled by the scripting environment.

Object containing any request parameters (GET, POST, Cookies, etc) and HTTP environmental variables.
This object contains all passed request parameters as named properties, no matter whether these have been submitted as URL-parameters, as part of a HTTP POST request, or as cookie values.
When more than one value is submitted for the same parameter name, req.data.paramname contains just a single (the first) value. That is why all parameters are additionally also provided with their values inside an array, through properites called req.data.paramname_array (the same parameter name, with an _array suffix attached).
Parameters can be grouped into objects using a "objectid[partid]" syntax in the parameter name. For example, a parameter name of "foo[bar]" will result in a req.data.foo object being created. The actual parameter value will be available at req.data.foo.bar. This feature can be used recursively, meaning that a parameter named "foo[bar][dong]" will result in req.data.foo.bar.dong.
Uploaded files are available in req.data as a MimePart object.
Additionally Helma sets the following HTTP environment variables if they are available:

Contributions¶
We welcome and encourage contributions of all nature; from pointing out an error or a potential problem, to translations, to feature requests, and pull requests.
We have a implemented a fully comprehensive developers' environment that comes with many functionalities, including its own Vagrant and Docker containers.
Attention
Developers' environment is only compatible with Python 3 and is only compatible with Unix-based systems (Linux and OS X). There are no plans to extend coverage to Python 2 as we intend to cease our support for Python 2 in the next major release. We do not support development on Window through this method.
To set up the developers' environment, start off by cloning our source code from GitHub, like so:
git clone https://github.com/neutronX/django-markdownx.git
One that's done, change to the cloned directory and run:
python3 dev.py -h
to see the options available.
Quick reference¶
And here is what you will see:
| Argument | Description |
|---|---|
-h , --help |
show the help message and exit. |
-v , --vagrant |
Install Vagrant development environment (requires Vagrant). |
-d , --docker |
Install Docker development environment (requires Docker). |
-c , --clean |
Clean up the development files (only the ones that have been automatically created). |
-run-vagrant |
Run vagrant development environment (runs --vagrant if the files don't already exist). Vagrant must be installed on your machine. |
-run-docker |
Run docker development environment (runs --docker if the files don't already exist). Docker must already be installed on your machine, and Docker Daemon must be up and running. |
-no-container |
Create development files without a container-based development environment (creates "manage.py" and "runtests.py"). |
--with-docs |
Install documentation development environment. |
--with-npm-settings |
Install npm installation environment, including package.json for front-end (TypeScript) development (requires node.js and npm ). |
--with-docs
and--with-npm-settings
are optional and need to be accompanied by one of the required arguments.- To save the changes made within the developers' environment, use
-c
or--clean
; and you will be asked if you would like to override the existing settings. Do not commit your changes before doing this.
Example¶
This will install the following files:
- manage.py
- runtests.py
- Makefile
- create_docs.py
It will also install the requirements for compiling the documentations. You do not need to create the documentations locally if you do not intend to change them. Although you are welcome to do so, for minor changes, it is probably easier to report an issue on GitHub as compiling the documentations can be somewhat tricky.
python3 dev.py -no-container --with-docs
Once done, please run:
python3 dev.py -c
to clean the installed files. If any of them have been altered, you will be asked for additional instructions as to whether to save the changes or discard them and hold onto the default.
Tests¶
Django packages require manage.py
and more often than not, settings.py
files to run. This introduces a challenge for testing apps outside of a fully constructed project environment. This is one of the reasons why we introduced the developers' environment, which allows for a fully setup container (Vagrant or Docker) to create an inclusive virtual server that can be used to run MarkdownX independently.
Attention
You need to have either Vagrant or Docker along with Oracle VirtualBox installed and configured to run either of these.
Note
Vagrant will attempt to download and install Ubuntu Xenial, whilst Docker uses the default operating system if one already exists.
To take advantage of this, you should clone the source code from GitHub as explained above, and depending on your container of choice, follow these instructions:
Vagrant¶
python3 dev.py --vagrant
Files will be created:
- Vagrantfile
- bootstrap.sh
- runtests.py
- manage.py
- package.json
python3 dev.py -run-vagrant
Connect to server using http://localhost:8000/
or http://<IP_ADDRESS>:8000/
Docker¶
python3 dev.py --docker
Files will be created:
- Dockerfile
- docker-compose.yml
- entrypoint.sh
- runtests.py
- manage.py
- package.json
python3 dev.py -run-docker
Connect to server using http://localhost:8000/
or http://<IP_ADDRESS>:8000/
Tip
Any changes made to the code whilst the container is up and running is automatically reflected without the need to restart the container.
Cleanup¶
Once done, please run:
python3 dev.py -c
to clean the installed files. If any of them have been altered, you will be asked for additional instructions as to whether to save the changes or discard them and hold onto the default.

MUSIC OF THE HEART A film review by David N. Butterworth Copyright 1999 David N. Butterworth
** (out of ****)
First let me dispense the answers to those burning questions which have been dogging you for weeks now.
Yes, "Music of the Heart" is directed by Wes Craven, the veteran shockmeister responsible for over 20 horror films including such blockbusters as the "Nightmare on Elm Street" and "Scream" series ("Scream 3," incidentally, is due out February 4th). "Music of the Heart," although (unintentionally) scary at times, is his first radical departure from the genre.
Yes, Meryl Streep wasn't the original choice to play Roberta Guaspari, the substitute teacher who revitalized an East Harlem public school and many of its students with her successful violin program (when no one wanted one) and the subject of Craven's new film. Madonna was the director's first pick, but she bailed out early citing "creative differences."
And yes, singer Gloria Estefan makes her acting debut in the film but blink and you'll miss her. Ms. Estefan spends more time nibbling on a carrot than she does acting, and her name up there alongside Streep's, Aidan Quinn's, and Angela Bassett's is like saying Kevin Costner starred in "The Big Chill."
If the storyline sounds at all familiar to you (and you'd be in the minority if it does), then that's because Roberta's success story was profiled in an Oscar®-nominated documentary from 1996 entitled "Small Wonders." I suspect few people saw that film, but someone clearly felt that this story was interesting enough to turn it into a large-scale Hollywood product with brand-name stars and a new song by Gloria to send the Miami Sound Machine groupies skipping off to Tower Records after the show.
"Let's dramatize it" someone must have said after seeing "Small Wonders." Unfortunately they did everything but.
The main problem with "Music of the Heart" is that it's devoid of drama, making it an extremely difficult film to pigeonhole. Nothing much really happens, no one tries to prevent it from happening, and when it does happen it's not very interesting anyway.
Streep, as you'd expect, is pretty good in the role, here passing on her usual accent-of-the-week. Streep's messy perm and bloodshot eyes aren't exactly flattering to Ms. Guaspari, but I suspect they're closer to the real Roberta than anything Madonna might have thrown her way. Quinn, on the other hand, seems strangely out of whack (he provides Roberta with the obligatory love interest, is sent packing halfway through the film, and then, surprise surprise, reappears for the big Carnegie Hall finale). And it's a pity to see the skilled Angela Bassett ("How Stella Got Her Groove Back," "Waiting to Exhale") stuck in a stock high school principal role.
That big Carnegie Hall fiddlefest, by the way, is shot with an incredible lack of flair by someone clearly more comfortable orchestrating decapitations and disembowelments. Even the presence of violin greats Isaac Stern and Itzhak Perlman can't pep it up any.
On the plus side, the kids who learn about the finer points of a violin bow have real charisma and with a little more drama than "Sorry, I forgot my violin today Miss Guaspari," "Music of the Heart" might have scored some much-needed points. Instead, it's a poor choice for Craven, an odd choice for Estefan, and a particularly good choice for Madonna.

public abstract class AsynchronousChannelGroup extends Object
An asynchronous channel group encapsulates the mechanics required to
handle the completion of I/O operations initiated by asynchronous channels
that are bound to the group. A group has an associated
thread pool to which tasks are submitted to handle I/O events and dispatch to
completion-handlers
that consume the result of
asynchronous operations performed on channels in the group. In addition to
handling I/O events, the pooled threads may also execute other tasks required
to support the execution of asynchronous I/O operations.
An asynchronous channel group is created by invoking the withFixedThreadPool
or withCachedThreadPool
methods defined here. Channels are bound to a group by
specifying the group when constructing the channel. The associated thread
pool is owned by the group; termination of the group results in the
shutdown of the associated thread pool.
In addition to groups created explicitly, the Java virtual machine
maintains a system-wide default group that is constructed
automatically. Asynchronous channels that do not specify a group at
construction time are bound to the default group. The default group has an
associated thread pool that creates new threads as needed. The default group
may be configured by means of system properties defined in the table below.
Where the ThreadFactory
for the
default group is not configured then the pooled threads of the default group
are daemon
threads.
| System property | Description |
|---|---|
java.nio.channels.DefaultThreadPool.threadFactory |
The value of this property is taken to be the fully-qualified name
of a concrete ThreadFactory
class. The class is loaded using the system class loader and instantiated.
The factory's newThread method is invoked to create each thread for the default
group's thread pool. If the process to load and instantiate the value
of the property fails then an unspecified error is thrown during the
construction of the default group. |
java.nio.channels.DefaultThreadPool.initialSize |
The value of the initialSize parameter for the default
group (see withCachedThreadPool ).
The value of the property is taken to be the String
representation of an Integer that is the initial size parameter.
If the value cannot be parsed as an Integer it causes an
unspecified error to be thrown during the construction of the default
group. |
The completion handler for an I/O operation initiated on a channel bound to a group is guaranteed to be invoked by one of the pooled threads in the group.
Where an I/O operation completes immediately, and the initiating thread
is one of the pooled threads in the group then the completion handler may
be invoked directly by the initiating thread. To avoid stack overflow, an
implementation may impose a limit as to the number of activations on the
thread stack. Some I/O operations may prohibit invoking the completion
handler directly by the initiating thread (see accept
).
The shutdown
method is used to initiate an orderly
shutdown of a group. An orderly shutdown marks the group as shutdown;
further attempts to construct a channel that binds to the group will throw
ShutdownChannelGroupException
. Whether or not a group is shutdown can
be tested using the isShutdown
method. Once shutdown,
the group terminates when all asynchronous channels that are bound to
the group are closed, all actively executing completion handlers have run to
completion, and resources used by the group are released. No attempt is made
to stop or interrupt threads that are executing completion handlers. The
isTerminated
method is used to test if the group has
terminated, and the awaitTermination
method can be
used to block until the group has terminated.
The shutdownNow
method can be used to initiate a
forceful shutdown of the group. In addition to the actions performed
by an orderly shutdown, the shutdownNow
method closes all open channels
in the group as if by invoking the close
method.

The resulting asynchronous channel group reuses a fixed number of

The executor

that
creates new threads as needed to execute tasks that are submitted to
handle I/O events and dispatch completion results for operations initiated
on asynchronous channels in the group. It may reuse previously constructed
threads when they are available.
The initialSize
parameter may be used by the implementation
as a hint as to the initial number of tasks it may submit. For
example, it may be used to indicate the initial number of threads that
wait on I/O events.
The executor is intended to be used exclusively by the resulting
asynchronous channel group. Termination of the group results in the
orderly shutdown
of the executor
service. Shutting down the executor service by other means results in
unspecified behavior.

directly. An implementation may mandate additional constraints.
The executor is intended to be used exclusively by the resulting
asynchronous channel group. Termination of the group results in the
orderly shutdown
of the executor
service. Shutting down the executor service by other means results in
unspecified behavior.
The group is created by invoking the openAsynchronousChannelGroup(ExecutorService,int)
method of the system-wide
default AsynchronousChannelProvider
object with an initialSize
of 0

The group terminates when all asynchronous channels in the group are
closed, all actively executing completion handlers have run to completion,
and all resources have been released. This method has no effect if the
group is already shutdown.
public abstract void shutdownNow() throws IOException
In addition to the actions performed by the shutdown
method, this method invokes the close
method on all open channels in the group. This method does not attempt to
stop or interrupt threads that are executing completion handlers. The
group terminates when all actively executing completion handlers have run
to completion and all resources have been released. This method may be
invoked at any time. If some other thread has already invoked it, then
another invocation will block until the first invocation is complete,
after which it will return without effect.

We thought of writing a comprehensive terms and conditions that would grant us exclusive use of your
personal data, since we know that you 99% won't read this
especially if you're a human being.
However, every single member of our team was/is
a hardcore CS major in college and as a result,
NO ONE on this team can write more than three coherent sentences in a row,
let alone an entire terms and conditions.
You might be wondering,
"hey, this terms and conditions so far seems relatively coherent
and seems to be longer than three sentences." Well, that's because this isn't written
by us; this is written by reddit user
u/englishmajor4hire
This rest of this document might seem odd to you since usually these legal shenannigans are written by human beans
called liars who have fancy degrees from prestigious lie schools (where they study Lie algebras in depth).
Originally, we were going to hire a country liar off of Fiverr to write the rest of the document for us, but we
found none on Fiverr or related websites (we did not realize the going price for a liar was much more than for an English major).
Basically,

We can't write, but we love machine learning, especially open source machine learning. There are
so many useful
applications of ML being deployed and coming up... maybe we'll finally have a way to make money.
To show support to OpenAI for advancing AI research and to cover our own asses in case one of you
are rich enough to hire liars and attack our honorable business, we'll continue
this terms and conditions, with all the rest of the text generated by the
GPT-2 language model starting with this sentence.
Feel free to fork and check out the FAQ if you don't understand anything. Language Model We're doing a two step convolutional architecture with single and double points in this document. You need to know a bit of ML before you can read this document. Check out this web-page (m2pdf.sourceforge.net) that helps explain ML in C#.
You can also find this explanation in this slideshows
called C# Master Class.
IMPORTANT: "What's the difference?"
Multiple Images
You can also use a single C# image of different sized images (per C# file) in the neural network. See examples/Demo_C_Manipulation.cshtml.
C# Syntax
This tutorial is written in C#. You can download the sample source code or use Visual C# 2012 Express. The tutorial is about neural networks, but it can be used to solve other kinds of problems.
"The net consists of two layers of input cells with 1 bit of input and output cells. The weights of the input cells are computed according
to the class of the objects in the neurons in the deep network.
It is unknown how neural network sizes are determined.
I. The internal representation of a neural network is in a fixed form of the input cells and the output cells, with up to 8 objects per cell. This way, 8-bit representation is adequate to represent various complex numeric functions.
II. The
basic structure of a deep network is: (1) the receptive fields with the 80 neurons in it, (2) the vector with the size of 8, 16, 32 bits, (3) the generator with the ratio of 2 and 3. However, the specific weights and biases can change for each object. Therefore, we can easily approximate this structure by a weighted average.
The weights are derived in such a way that each weighted average has a value closer to that of the previous one. Let's call them g for the quality of the generator and b for the quality of the weights. In this way we can easily get all the weights associated with each object.
The generator is called B to distinguish it from the others, but its inputs remain the
same. To generate the g weight, we draw 2 random points on the input image. Let's say we draw them from the $[0,1]$-coordinate system. These points are then multiplied by the g-weight, yielding the final weight. Since $[0,1]$ is in the unit-coordinate system, we'll assume that this is
also the g-weight in the canonical unit-length unit.
Animate the user's head image with a sinusoidal box --radius to extend out to infinity, and also with a constant sinusoidal f-speed to animate the gradient. This uses the two circles described above.
And this is how the final sequence looks like (from top to bottom
The continuous movement takes place on the x-axis and the gradient is on the y-axis, so this is an easily interpretable animation.
This animation is slightly different because the boxes animate to their minimum and maximum dimensions, and there's no solid color at the location of the box at any point. I also changed the animated gradient because it doesn't look
very good to create a constant black instead of a gradient with a flashing or pulsing. To create the black, I composed two colors: one that's completely black, and one that gradually changes the opacity. The black background color basically adds a blur to the animation
that makes it less noticeable, since it doesn't really fill the space that much. But it adds a bit more visual noise to make it more subtle.
Step 11
To make the battery indicator flash faster and slower, I used a gradient that moves from a bright to dark color and moves at a slower speed. I replaced the opacity with a third variable that gradually changes the opacity depending on the time of day.

What's next?
That's all! It is possible to use this approach with any method of vibration – obviously the voltage should be the same or less than that of the battery,
it's also possible to lower it if you want. Let me know if you have any ideas.

Follow these steps to save sklearn
models into the ObjectStore:
model_key = "model"
GetFilePath
method with the key.file_name = self.ObjectStore.GetFilePath(model_key)
This method returns the file path where the model will be stored.
dump
method the file path.joblib.dump(self.model, file_name)
If you dump the model using the joblib
module before you save the model, you don't need to retrain the model.


Wormholes
问题描述 :
While exploring his many farms, Farmer John has discovered a number of amazing wormholes. A wormhole is very peculiar because it is a one-way path that delivers you to its destination at a time that is BEFORE you entered the wormhole! Each of FJ’s farms comprises N (1 ≤ N ≤ 500) fields conveniently numbered 1..N, M (1 ≤ M ≤ 2500) paths, and W (1 ≤ W ≤ 200) wormholes.
As FJ is an avid time-traveling fan, he wants to do the following: start at some field, travel through some paths and wormholes, and return to the starting field a time before his initial departure. Perhaps he will be able to meet himself :) .
To help FJ find out whether this is possible or not, he will supply you with complete maps to F (1 ≤ F ≤ 5) of his farms. No paths will take longer than 10,000 seconds to travel and no wormhole can bring FJ back in time by more than 10,000 seconds.
输入:
Line 1 of each farm: Three space-separated integers respectively: N, M, and W
Lines 2..M+1 of each farm: Three space-separated numbers (S, E, T) that describe, respectively: a bidirectional path between S and E that requires T seconds to traverse. Two fields might be connected by more than one path.
Lines M+2..M+W+1 of each farm: Three space-separated numbers (S, E, T) that describe, respectively: A one way path from S to E that also moves the traveler back T seconds.
输出:
样例输入:
2 3 3 1 1 2 2 1 3 4 2 3 1 3 1 3 3 2 1 1 2 3 2 3 4 3 1 8
样例输出:
NO YES
温馨提示:
For farm 2, FJ could travel back in time by the cycle 1->2->3->1, arriving back at his starting location 1 second before he leaves. He could start from anywhere on the cycle to accomplish this.

TIFFReadTile
Section: Misc. Reference Manual Pages (3T)
Updated: December 16, 1991
Index
Return to Main Contents
NAME
TIFFReadTile - read and decode a tile of data from an open
TIFF
file
SYNOPSIS
#include <tiffio.h>
tsize_t TIFFReadTile(TIFF* tif, tdata_t buf, uint32 x, uint32 y, uint32 z, tsample_t sample)
DESCRIPTION
Return the data for the tile
containing
the specified coordinates.
The data placed in
buf
are returned decompressed and, typically, in the native byte-
and bit-ordering, but are otherwise packed (see further below).
The buffer must be large enough to hold an entire tile of data.
Applications should call the routine
TIFFTileSize
to find out the size (in bytes) of a tile buffer.
The
x
and
y
parameters are always used by
TIFFReadTile.
The
z
parameter is used if the image is deeper than 1 slice (ImageDepth>1).
The
sample
parameter is used only if data are organized in separate planes (PlanarConfiguration=2).
NOTES
The library attempts to hide bit- and byte-ordering differences
between the image and the native machine by converting data
to the native machine order.
Bit reversal is done if the
FillOrder
tag is opposite to the native machine bit order.
16- and 32-bit samples are automatically byte-swapped if the
file was written with a byte order opposite to the native
machine byte order,
RETURN VALUES
TIFFReadTile
returns -1 if it detects an error; otherwise the number of
bytes in the decoded tile is returned.
DIAGNOSTICS
All error messages are directed to the
TIFFError(3T)
routine.

I went to my GP today, because in the last few months, I've experienced severe panic attacks (caused by mild hppd).
So he gave me a strip with 7 Effexor for free (Denmark, free health insurance for the people:)
I got home, and swallowed a capsule (containing 75 mg). And now after no more than 2 hours, I'm experiencing some facinating changes in my vision (my hppd really freaks out) when I close my eyes, I see intense COLORED fractals, moving to the music. Iím feeling a bit distorted, and warm and fuzzy, there's alot of floaters, and everything really seems to wave back and forth. The textbox Iím writing this in now seems to be endless, expanding thru the screen, and onto my walls.
Iíve read alot of very bad things about Effexor, and I do not doubt that it's a drug not to be taken unless the only other choice is death. So this was my first and last experience with Effexor.
Experience Reports are the writings and opinions of the individual authors who submit them.
Some of the activities described are dangerous and/or illegal and none are recommended by Erowid.

If you've ever had to drop some HTML/CSS in someone else's site, you know that CSS specificity issues can be a pain to deal with. All of a sudden your .button class has a huge font and underlined text, and the rule that's applying it is so specific that you can't hope to come up with a generalized solution. Javascript CSS injection seeks to solve that problem.
The idea is that inserting a <style> element into the DOM gives us better control than modifying inline style properties. With a few simple transformations, your CSS can be modified to be the most specific on the page, and to only target the elements you care about.
Note that this plugin does not absolutely guarantee the most specific selector possible in CSS. The selectors are comprised of the tag-id combo for every ancestor node of the target, and the node itself. To get a more specific selector, we would need to explicitly target every attribute for each node. But that's slow and not cross-browser compatible. That said, the situations where someone would have a more specific selector are rare and mostly contrived. You can also use the important option to get around the problem.
 Some problems I've run into:
With injected <style> attributes, we get all the benefits that come with external stylesheets, along with all the power of javascript.
All options available to injectCss are available to the jQuery version too.
injectCss(document.getElementsByName("div")[0], "* {background:green; color:white;}");
$("div:first").injectCss("* {background:green; color:white;}");
removeInjectedCss(document.getElementsByName("div")[0]);
$("div:first").removeInjectedCss();
injectCss(document.getElementsByName("div")[0], "div {background:green; color:white;} a {text-decoration: none;}");
injectCss(document.getElementsByName("div")[0], "* {background:green; color:white;}", { important: true });
injectCss(document.getElementsByName("div")[0], "self {background:green; color:white;}");
$("div:first").injectCss("self {\ display: block;\ position: absolute;\ visibility: hidden;\ }", { important: true }).each(function() { console.log($(this).width()); }).removeInjectedCss();
