Burn Language Analyzer

Language server launcher for the Burn programming language.

Burn ships its language server inside the compiler (burn lsp), so it always understands exactly the same language as the compiler. burn-analyzer is a tiny, dependency-free binary that starts burn lsp over stdio, so editors that are configured to run burn-analyzer keep working.

Features

Everything comes from burn lsp:

• Error reporting: syntax and type errors with exact line and column while you type
• Code completion: locals, globals, types, built-ins and members after .
• Hover information: inferred types and signatures
• Go to definition: including into imported files
• Document outline
• Formatting

Usage

The Burn toolchain installer already provides burn-lsp, which is the same language server:

curl -fsSL https://raw.githubusercontent.com/burnlang/burn/master/install.sh | sh

To install burn-analyzer as well:

cargo install --path .
burn-analyzer

burn-analyzer looks for the burn executable in $BURN_PATH, next to its own binary, and on $PATH. You can also point your editor at burn lsp directly.

Neovim

vim.lsp.start({ name = "burn", cmd = { "burn-analyzer" }, root_dir = vim.fn.getcwd() })

Helix

[language-server.burn]
command = "burn-analyzer"

[[language]]
name = "burn"
scope = "source.burn"
file-types = ["bn"]
language-servers = ["burn"]

syntaxes/burn.tmLanguage.json and language-configuration.json contain the Burn grammar for editors that use TextMate grammars.
