Feature details

Syntax highlighting

There is a known bug that it isn't very consistent when it comes to highlighting top level def calls. Other than that, should be fine.

Build system

For this and REPL, you need to have Janet binary under one of directories listed in PATH environment variable.

jpm

jpm is used as default build system, if project.janet file is present in the root directory.

Windows build note: you need to set vcvars_bat_path variable in your Sublime Text settings to match MSVC batch file used for initialization of build environment (e.g. "C:\\Program Files\\Microsoft Visual Studio\\2022\\Professional\\VC\\Auxiliary\\Build\\vcvars64.bat"). See MS documentation about command line toolset for extra details.

There are also shortcuts for jpm clean and jpm test available in command palette.

Single script evaluation

Strictly talking, it isn't a build system, just an evaluation of current file using available Janet interpreter. Partial evaluation of expressions isn't supported yet.

Integration with SublimeREPL

SublimeREPL upstream seems to be not really maintained for some years, but still works. Out of the box, if you have it installed, after adding Janet package to Sublime Text, its REPL should be available under Tools → SublimeREPL → Janet. However, if you want it to be available through the command palette, you should do the following:

1. Go to SublimeREPL installation directory (under user packages).
2. Create a directory there config/Janet.
3. Copy file SublimeREPL/Main.sublime-menu from this repo to config/Janet.
4. Create a file config/Janet/Default.sublime-commands with the following content:

[
    {
        "caption": "SublimeREPL: Janet",
        "command": "run_existing_window_command", "args":
        {
            "id": "repl_janet",
            "file": "config/Janet/Main.sublime-menu"
        }
    }
]

Ctrl+, shortcuts still don't work, and I ain't sure if I did something wrong or just the age of SublimeREPL projects reveals itself.
