Code editors: Eclipse, Notepad++, TextPad, SciTE



Eclipse is an IDE (Integrated Development Environment). It intends to facilitate the developer's work with integrated tools. Interesting features are:

  • a powerful editor with completion and refactoring capabilities
  • version repository access (CVS, SVN)
  • debugging tools / profiling
  • test framework

You don't need to use Eclipse to integrate your model in Capsis. Eclipse IDE has very advanced functionalities and can be a bit complex for occasional programmers. If you are not sure that Eclipse is for you, you can still use your own editor (like Notepad++, TextPad or SciTE), see below.


We recommend to use the last version of Eclipse : 2019-09 (at last documentation editing time)

Install Capsis with SVN

Build Capsis

  • Capsis4 will be imported as a Java Project. Eclipse will manage compilation.
  • You need to customize the Java build path:
    • go in the project's Properties > Java Build Path
    • in Source tab:
      • ensure that Output folder (Source folders on build path section) and Default output folder are set to capsis4/class, check 'Allow output folders for source folders'
      • some patterns have to be excluded: capsis/lib/numerics/ , crobas/ and scilab/

  • in Libraries tab:
    • ensure that all .jar from capsis4/ext are in the Java Build Path ; if needed, add them by using the Add JARs… button;
    • ensure also that the JRE (Java Runtime Environment) installed on your machine is in the Java Build Path ; if needed, add it by using the Add Library… button, choose JRE System Library then Alternate JRE and choose the JRE installed on your machine, should be Java version 1.8.

  • Configure the compiler:
    • Select 'Java compiler' in the lateral list
    • Select 'Enable project specific settings'
    • Compiler compliance level: 1.8

Run Capsis

  • Click on the Run Button.
  • You can add a particular configuration
    • Run → Run configuration
    • Select Java Application
    • New launch configuration
    • Specify the main class (here


  • If you have to press twice the run button before Capsis really starts then replace the file capsis4/.project by the following one :
<?xml version="1.0" encoding="UTF-8"?>
  • If the visu 3D do not work when you launch capsis with Eclipse under Windows, then add the path of the corresponding nativewindow_jvm.dll among your system variables. For example, for a windows 64 : /capsis4/ext/windows64/nativewindow_jvm.dll (does not work with recent version of eclipse)

Configuring Textpad to open the file in error at the given line

After a compilation, if there are errors, it is possible to double click on the “file:line” reference to open the file for correction.

Check this configuration :

  • Configuration > Preferences > Tools
  • Select javac_capsis
  • Check the regular expression in the matching field (1)

If trouble with the expressions (double clicking does not open the file):

  • Help > “Regular expressions matching the compilation errors” link
  • Copy the expression for java; e.g. ^\([A-Za-z]:[^:]+\):\([0-9]+\):
  • Paste it in the field (1) upper

SciTE (Linux user)

Presentation & Download

Scite is a simple editor available on Linux system. Use your system installer to install it.

For instance, for Ubuntu distribution use:

sudo apt-get install scite 

Configuration with Capsis

  • Go to Options → Open User Options file
  • Add the following lines in the file (Replace my_capsis_dir by the full path of your capsis4 directory)
command.compile.*.java=sh my_capsis_dir/bin/ $(FileNameExt)*.java=sh my_capsis_dir/bin/ $(FileNameExt)
command.go.*.java=java $(FileName)
  • Save the file

You can now compile in Scite !!

See this note if you want to compile Capsis and Jeeb in Scite.
