# tree-sitter-bend
Bend grammar for [tree-sitter](https://github.com/tree-sitter/tree-sitter).
# Usage
## Neovim
### Installation
First of all, you need to install [nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter) with your favorite dependency manager, such as [lazy.nvim](https://github.com/folke/lazy.nvim).
After that, you should add this code snippet to your Neovim configuration right after calling `require("nvim-treesitter.configs").setup()`. The configuration file can be found or created at `~/.config/nvim/init.lua`.
```lua
local parser_config = require("nvim-treesitter.parsers").get_parser_configs()
parser_config.bend = {
install_info = {
url = "https://github.com/HigherOrderCO/tree-sitter-bend",
files = { "src/parser.c", "src/scanner.c" },
branch = "main",
},
}
vim.filetype.add({
extension = {
bend = "bend",
},
})
vim.treesitter.language.register("bend", { "bend" })
```
Using lazy.nvim, your configuration could look like this:
```lua
plugins = {
{
"nvim-treesitter/nvim-treesitter",
build = ":TSUpdate",
config = function ()
local configs = require("nvim-treesitter.configs")
configs.setup({
ensure_installed = { "c", "lua", "vim", "vimdoc", "query", "elixir", "heex", "javascript", "html" },
sync_install = false,
highlight = { enable = true },
indent = { enable = true },
})
local parser_config = require("nvim-treesitter.parsers").get_parser_configs()
parser_config.bend = {
install_info = {
url = "https://github.com/HigherOrderCO/tree-sitter-bend",
files = { "src/parser.c", "src/scanner.c" },
branch = "main",
},
}
vim.filetype.add({
extension = {
bend = "bend",
},
})
vim.treesitter.language.register("bend", { "bend" })
end
}
}
require("lazy").setup(plugins)
```
Finally, install the language grammar into the tree-sitter plugin by running `:TSInstall bend` on Neovim.
### Syntax highlighting
For syntax highlighting to work, you have to create a `queries/bend` directory in your Neovim configuration root and copy the file [highlights.scm](./queries/highlights.scm) into it.
You might have to update the Tree-sitter plugin afterwards by running `:TSUpdate` on Neovim.
## VSCode
You can use syntax highlighting on VSCode through our VSCode extension, check out its repository [here](https://github.com/HigherOrderCO/bend-language-server).
# Contributing
The grammar descriptions can be found in the directory [./grammar](./grammar/), called by the main file [./grammar.js](./grammar.js). Most other files are automatically generated by the tree-sitter CLI using `tree-sitter generate`.
