This is an incredibly basic tool for Python 3.x for use when creating images of code, e.g., for slides with code snippets in. It takes a given file and using Pygments it converts it into a syntax highlighted Pango compatible output, which can in turn be converted to an image with Pango.
usage: pangosyntaxhighlight.py [-h] [--language LANGUAGE] [--list-languages] [--style STYLE] [--list-styles] inputfile outputfile
Syntax highlight code in Pango format using Pygments
positional arguments:
inputfile the input file
outputfile the output file
options:
-h, --help show this help message and exit
--language LANGUAGE the syntax language of the input file (otherwise auto-detected/auto)
--list-languages list available languages (lexers)
--style STYLE highlighting style, e.g., vs
--list-styles list available styles
To convert myfile.cpp to the image myfile.png:
python3 pangosyntaxhighlight.py myfile.cpp output.txt && pango-view --markup --font=mono -qo myfile.png output.txt
Specifying a specific programming language for a generic .txt file:
python3 pangosyntaxhighlight.py code.txt output.txt --language cpp && pango-view --markup --font=mono -qo code.png output.txt
Run with --list-languages to get a list of supported languages/lexers by short names (e.g., cpp, python, etc.). Additional short names may also work, see the available lexers list for the complete list. For example, --list-languages lists delphi, not pascal, but the latter will work.
Specifying the vs highlighting style:
python3 pangosyntaxhighlight.py myfile.cpp output.txt --style vs && pango-view --markup --font=mono -qo myfile.png output.txt
Run with --list-styles to get a list of styles supported by your system. Style previews are available here.
To change the resolution of generated images use the --dpi flag for pango-view:
python3 pangosyntaxhighlight.py myfile.cpp output.txt && pango-view --markup --font=mono --dpi=120 -qo myfile.png output.txt
