This repository contains color schemes for Joe's Own Editor, as well as a handful of miscellaneous utilities to generate and convert color schemes.

If you're only looking for color schemes, you will find them in the custom and output directories. Those in custom are hand written, and those in output are generated from VIM schemes found in the vim-schemes directory.

More color schemes are available from the base16-joe repository, which contains the templates necessary to build JCF files for the color schemes supported by the base16 project.

The create256.py script in this repository will convert the GUI colors from those output files, and amend xterm-256 sections to each one. This script is to be run before checking in JCF files to that repository.

Most of the schemes here are generated from the VIM script schemes, which is performed by the convertvim.py program. The Makefile here is also geared towards automating this process:

make -j4 all

• This will create the virtualenv for you and install dependencies if not already done.
• The all target is necessary to build all schemes. The default target, prod only builds those schemes that are included in the default distribution of JOE.
• You'll want to build with multiple cores (-j) for the fastest result. Color scheme generation is an expensive operation due to the complications converting them to xterm-256 (properly) and matching terminal colors.

Additional options are set in overrides.json, which specifies things like attributions, color overrides, and the like.

This conversion process only works with a subset of VIM color schemes. Since I didn't implement a full VIM parser and runtime, any scheme that cheats and uses any kind of function will fail to convert. Only schemes that use the straightforward hi/highlight/hi link commands will work correctly.

Many schemes do, however, use branching to check for enabled options -- for example, to switch between light and dark versions. I've "amended" the syntax to add do and dont, indicating which branches should be taken or skipped. The parser will properly match if's and else's beyond that.
