tree-sitter-blink

Tree-sitter grammar for the Blink programming language.

Provides syntax highlighting and structural parsing for .bl files in editors and tools that support tree-sitter.

---

Editor Setup

Neovim (nvim-treesitter)

Add to your nvim-treesitter config:

require("nvim-treesitter.parsers").get_parser_configs().blink = {
  install_info = {
    url = "https://github.com/blinklang/tree-sitter-blink",
    files = { "src/parser.c" },
    branch = "main",
  },
  filetype = "bl",
}

Then install:

:TSInstall blink

Helix

Add to ~/.config/helix/languages.toml:

[[language]]
name = "blink"
scope = "source.blink"
file-types = ["bl"]
roots = []
comment-token = "//"

[language.grammar]
source = { git = "https://github.com/blinklang/tree-sitter-blink", rev = "main" }

Then fetch and build:

hx --grammar fetch && hx --grammar build

ast-grep Setup

ast-grep enables syntax-aware search and rewrite on Blink source files.

Run this one-liner to download, compile, and configure:

curl -sSL https://raw.githubusercontent.com/blinklang/tree-sitter-blink/main/install-ast-grep.sh | bash

This compiles the grammar and installs it to ~/.config/ast-grep/. The script will print an alias to add to your shell profile:

ast-grep() { command ast-grep --config ~/.config/ast-grep/sgconfig.yml "$@"; }

Then:

# Find all calls to foo with one argument
ast-grep run -p 'foo($X)' -l blink src/

# Rename foo to bar across all .bl files
ast-grep run -p 'foo($X)' -r 'bar($X)' -l blink src/

Requirements: a C compiler (gcc or clang) and curl.
