- map[K]V: insertion-ordered hash maps, literals, m[k] += 1, has/get/remove/keys/values
- -> T! / -> !, return error(...), or <value>, or { err }, try; fallible int/float/read_file/write_file/delete_file
- for i, x in list / for k, v in map

Finch in Kate

Syntax highlighting and the Finch language server for Kate (and KWrite / KDevelop, which share Kate's highlighting engine).

Install

editors/kate/install.sh

It copies finch.xml to ~/.local/share/org.kde.syntax-highlighting/syntax/ and adds a finch entry to ~/.config/kate/lspclient/settings.json (your other servers are kept). Then:

  1. Restart Kate.
  2. Settings → Configure Kate → Plugins: enable LSP Client (and Build & Run for the next part).
  3. Make sure finch is on your PATH (finch version in a terminal).

Open a .fch file: errors appear as you type, hovering shows types and docs, Ctrl+Space completes (fields and methods after .), Go to Definition and the Symbols outline work, and parameter hints pop up inside (…).

Running and building

Build & Run plugin → Add target set, then add targets with these commands (the working folder can be %d, the folder of the current file):

Target Command
Run finch run %f
Build finch build %f

Give one of them a shortcut in Settings → Configure Keyboard Shortcuts (search for "Build"). Finch's errors have the file:line:column: error: form, so Kate lists them and jumps to the line on click.

By hand

  • Highlighting: copy finch.xml into ~/.local/share/org.kde.syntax-highlighting/syntax/ (Windows: %LOCALAPPDATA%\org.kde.syntax-highlighting\syntax\).
  • Language server: Settings → Configure Kate → LSP Client → User Server Settings, and add the finch entry from lspclient.json inside "servers".
