hapax-lsp
A language server for Squarp Hapax instrument definitions: diagnostics, highlighting, completion and a fix-all action, in any editor with an LSP client.
Validation comes from hapax-tui, so the editor reports exactly what hapax validate reports.
Install
uv tool install git+https://github.com/claytron/hapax-lsp
This puts hapax-lsp on your PATH; it speaks LSP over stdio.
Settings
| Setting | Default | Meaning |
|---|---|---|
fw |
3.21 |
Target Hapax OS, 1.12 to 3.21 |
warn |
warn in ~/.config/hapax/config.toml, else true |
Report warnings as well as errors |
Send them as initializationOptions, or as workspace/didChangeConfiguration settings under a hapax key.
Neovim (0.11+)
Add the bundled runtime directory and enable the server:
vim.opt.runtimepath:append("/path/to/hapax-lsp/editors/nvim")
vim.lsp.enable("hapax")
Instrument definitions are .txt files, so ftdetect/hapax.lua marks a .txt buffer as hapax when its first non-comment line is a directive (VERSION, TRACKNAME, TYPE, ...) or a section header.
Other .txt files stay text.
Highlighting comes from semantic tokens, linked to your colour scheme's @lsp.type.* groups.
Run the fix-all action with vim.lsp.buf.code_action().
Other editors
Map Hapax .txt files to a hapax language however your editor allows, for example by the directory you keep instruments in, and run hapax-lsp for it.
