Language server protocol (LSP) support for Zed
Setup
Assumes ast-grep is available globally. You must install it yourself and either make it available on the $PATH or manually override the binary path (see below).
Using a non default installation of ast-grep
If you cannot or do not want to have ast-grep globally installed on your system, you must manually specify the path to the ast-grep executable. Note that an absolute path is necessary and placeholders (ex. ~, $HOME) are not expanded.
Example:
{
"lsp": {
"ast-grep": {
"binary": {
"path": "/Users/user-name/.nix-profile/bin/ast-grep"
}
}
}
}Passing the sgconfig.yml path to ast-grep
If your sgconfig.yml is not at the project root, you must manually specify it's location in Zed's project specific settings (normally in .zed/settings.json). You can do so by overriding the command line arguments sent to ast-grep but don't forget the lsp argument. Note that an absolute path is necessary and placeholders (ex. ~, $HOME) are not expanded.

}Language Support
Toml
Ast-grep doesn't support toml by default, but it's easy to add it following the instruction for custom languages.
Tested with tree-sitter-grammars/tree-sitter-toml.
