""" Style editor for the wxStyledTextCtrl.

Reads in property style definitions from a config file.
Modified styled can be saved (and optionally applied to a given list of STCs)

It can also maintain a Common definition dictionary of font names, colours and
sizes which can be shared across multiple language style definitions.
This is also used to store platform spesific settings as fonts and sizes
vary with platform.

The following items are defined in the stc-styles.rc.cfg file.

common.defs.msw - Common definition dictionary used on wxMSW
common.defs.gtk - Common definition dictionary used on wxGTK
common.styleidnames - STC styles shared by all languages

Each supported language defines the following groups:
[<language>]
displaysrc - Example source to display in the editor
braces - Dictionary defining the (line, column) for showing 'good' and 'bad'
         brace matching (both keys optional)
keywords - Space separated list of keywords
lexer - wxSTC constant for the language lexer
styleidnames - Dictionary of language spesific style numbers and names

[style.<language>] - The users current style values
[style.<language>.default] - Default style values (can be reverted from)

0 or more predefined style groups or 'themes'
[style.<language>.<predefined name>]

Currently the following languages are supported:
    python, html, xml, cpp, text, props
Other languages can be added by just defining the above settings for them in
the config file (if wxSTC implements them).

Use the initSTC function to initialise your wxSTC from a config file.
