Caffeine Language Support

VS Code extension for Caffeine, the language that compiles service expectations to reliability artifacts.

Quick Start

Install the extension from the VS Marketplace or Open VSX
Install the Caffeine binary via Homebrew: brew install caffeine-lang/tap/caffeine
Open a .caffeine file
That's it. The extension finds the binary and spins up the language server automatically.

If you installed Caffeine somewhere nonstandard, point the extension at it via the caffeine.serverPath setting.

Features

Syntax highlighting
LSP integration (diagnostics, completions, go-to-definition, etc.)
Format on save (enabled by default)
Smart indentation, bracket matching, code folding

Configuration

Setting	Description	Default
`caffeine.serverPath`	Path to the `caffeine` binary. Leave empty to auto-detect from Homebrew or PATH.	`""`
`caffeine.trace.server`	Trace LSP communication between VS Code and the language server. Useful for debugging.	`"off"`

The trace.server setting accepts "off", "messages", or "verbose". If something looks off with the language server, flip it to "verbose" and check the output panel.

Commands

Command	Description
`Caffeine: Restart Language Server`	Restart the language server without reloading the whole editor

Requirements

You need the Caffeine binary installed. The extension looks for it in this order:

Custom path from caffeine.serverPath (if set)
Homebrew -- /opt/homebrew/bin/caffeine (Apple Silicon) or /usr/local/bin/caffeine (Intel)
System PATH

Requires VS Code 1.75+.

Troubleshooting

Language server not starting? Check that caffeine lsp runs from your terminal. If it does, the extension should pick it up. If not, set caffeine.serverPath explicitly.
Weird LSP behavior? Set caffeine.trace.server to "verbose" and check the Caffeine output channel in VS Code's Output panel.
Still stuck? Open an issue.
