How to add syntax-highlightning to SilverCity that exists in Scintilla

First download the !SilverCity package and the latest Scintialla package.

root = where you unpacked SilverCity

lang = the language you want to add

• Download the latest scintilla. So that you have all the latest lexers. in the SilverCity directory do:

  • tar -xvzf scintillaXXX.tgz
  • python setup.py build
  • cd root/PySilverCity/Src
  • python write_scintilla.py ../../scintilla/include ../../scintilla/include/Scintilla.iface tmp.py
  • rm ../SilverCity/ScintillaConstants.py
  • mv tmp.py ../SilverCity/ScintillaConstants.py

• Now you change to the root/PySilverCity/SilverCity and have to create a module lang.py

  • We are using the YAML.py as template so do 'cp YAML.py lang.py'

  • in lang.py replace every occurance of Yaml with lang

  • replace "from ScintillaConstants import SCLEX_YAML" to use your language lexer.

  • replace occurance of SCE_YAML with the equivalant for your language lexer

  • To find the equivalent constant for lang look into ScintillaConstants.py

  • change the langue info at the.

    • Change suffixes to what the new lang has. So that one can deduce from filename what lexer to use.

  • Open root/scintilla/src/Lex'lang' see how many WordList arguments are to the function.

    • In lang.py add so many WordList in self._keywords in the langLexer.__init__ function
    • Check the CPP.py as example.

  • Add the keywords for the language in the Keywords module

  • Add the lang in in the do_registration function in the module LanguageInfo

• Fix css. So that you get colours when you view the html page.

  • Open root/PySilverCity/SilverCity/ScintillaConstants.py
    • Figure out what the language you added has for lexer keywords, that start with SCE_xx. For example python has SCE_P_something.
  • Add the keywords in root/Scripts/generate_css.py see the other languages as example.
  • cd root/Scripts
  • python generate_css.py >! code.css

• Add the lang in the root/setup.py script

  • Open root/setup.py
  • Search for py_modules variable and add Scintilla.lang to it

• Install SilverCity with the new lang.

  • cd root
  • python setup.py install

In Trac

For the syntax-highlightning to take effect you have to add directives for colouring in code.css that normally located in in /usr/share/trac/htdocs/css/code.css. You also have to add the language in the …/trac/mimeviewer/silvercity.py. But se the patch in ticket #606
