Supported Scilab Version
Creation Date
December 29, 2011
            UPDATED for Scilab 5.4.0a    .sce .sci .tst .start files supported
Functions and related synopses of 3 main ATOMS modules SIVP, plotlib and lycee
are included.
The free high level Notepad++ external editor can propose an advanced feature
(unavailable in the embedded Scilab editor): All calling sequences of a function
can be displayed when typing the opening "(". This feature is enabled
by the scilab.xml file. It greatly helps in reminding on-the-fly the expected
lists of arguments.

scilab.xml also enables completion of function names through the <em>full
list</em> of Scilab's functions.
Other Notepad++ features such as syntax colorization, folding / unfolding of
block of statements, parentheses or brackets or braces matching, etc.. are
defined and proposed for Scilab through the UserDefineLang.xml file.
The two main subsets of reserved Scilab keywords (built-in functions, and
macros) are extensively given for syntax highlightment, including undocumented
utility functions.

REMARKS about syntax parsing rules
* "/" cannot be declared as an operator because Notepad++ couldn't
distinguish it from "//" for comments.
* The keywords "then", "else", "elseif",
"case", or "catch" are highlighted like other ones, but
Notepad++ does not allow to fold / unfold sub-blocks opened with them, because
they have no specific ending words. 
* The single quote _'_ cannot be declared as an alternative string delimiter.
Otherwise, Notepad++ would parse the ' transposition operator as the opening of
a string, making a big part of the following code wrongly parsed.

HOW TO SET Notepad++ to autocomplete Scilab functions and args:
In Notepad++ : 
In the menu Settings => Preferences => Tab: Back-up/Auto-completion:
In the Auto-completion frame, the only item that should NOT be checked is
"Word completion".
Management of files provided through this module is described below.

scilab.xml enables the completion of Scilab functions and the display of their
calling sequences (when typing the opening parenthesis).
scilab.xml must be stored in the ~\plugins\APIs\scilab.xml Notepad++
installation directory (most often in C:\Program files\Notepad++\plugins\APIs)
scilab.xml is built with the synopses extracted from the Scilab official help
The extensive set of ~2900 Scilab calling sequences is proposed.
For each completed function, all allowed calling sequences are displayed.

the root of the Notepad++ installation directory (for all forthcoming Notepadd++
Your own UserDefineLang.xml file may contain rules for customized languages
other than Scilab. This is why it is preferable to properly import this release
for Scilab with the Import command (Menu Settings => Import), or to edit it and
copy/paste the <="" userlang=""> block for Scilab in it.

I am using Windows 7 64 bits and I have downloaded scilab.xml into C:\Program files
(x86)\Notepad++\plugins\APIs). After launching Notepad++, the Scilab language is not
listed to allow formating text.
Please advise.
Thanks and regards,

Hello Rafael,

Notepad++ detects the language according to the file extension defined in the
UserDefineLang.xml, before using the related completion API. If you have installed
only scilab.xml, you won't get neither the syntax colorization nor the completion.
Have you instal both files as described in the descriptionsabove?

I am sorry as, indeed, I had only downloaded one of the files.
After storing 'UserDefineLang.xml' in  'C:\Users\my_user_name\AppData\Roaming\Notepad++'
it worked like a charm.
Many thanks!

Dear Samuel,

Is it possible to run scilab with notepad++ (menu run commands)?

And if possible, how can i do that?

Thank you,
Have a nice day,

Hello Bastien,

It is rather a Notepad++ question, and a very relevant one.
IMO, it should be possible... with some work.
Here are the Notepad++ pointers that i have found around this topic:

* A Np++ user has released a code to execute into R 
  some lines selected in the Np++editor: 
  Some equivalent for Scilab would answer to your need.

* There is a RunMe plugin : => See RunMe
  Moreover, the latest release of this plugin looks not compatible
  with the lastest Notepad++
  How to use RunMe is not clear to me 

* The last potentially useful plugin that i have found is 

It is almost clear that it should be possible to send from Np++
content to a NEW Scilab session. But targetting an open one is 
something else. The R example might likely be adapted (i have
tested it with R, without success :/ )

Hoping that this could help

Dear Samuel!

Thank you for all the information.

Here is the command line to run scilab with NppExec (Npp v5.1.4)

"C:\Program Files\scilab-4.1.1\bin\scilex" -nw -f MyScript.sce

(this line runs scilab in batch mode)

I think using NppExec is the better and simplest solution!

Have a nice coding night!!!

Of course, you have to change the current directory in the scilab.start file.

Using the NppExec plugin, you can load a file into Scilab by doing the following:

Press F6 to bring up the NppExec window
Type the following:

"C:\Program Files\scilab-5.4.0\bin\Scilex.exe" -f $(FILE_NAME)

Press Ok button.
This should open a window called console in Notepad++ and execute the code in your file.
