Vorto ships with built-in definitions for 21 languages. Each definition covers the file extensions that map to the language, which LSP server to use, and any default formatter. Tree-sitter grammar recipes are included for all languages except SQL, which has a recipe but no bundled query files. You do not need any configuration to use these languages — install the grammar and the LSP server binary, and Vorto picks them up automatically.

Notes on specific languages

TypeScript and TSX each have a separate language entry so that the JSX-aware tsx grammar and its queries are used for .tsx files. Both languages try vtsls first and fall back to typescript-language-server; whichever binary is found on PATH is used. Configure lsp = [...] in [languages.typescript] if you want to restrict to a single server. C and C++ both use clangd. .h files are routed to C by default; C++-specific headers (.hpp, .hh, .hxx) are routed to C++. JavaScript includes .jsx, .mjs, and .cjs extensions in addition to .js. Markdown installs only the block-level grammar from tree-sitter-grammars/tree-sitter-markdown. The inline grammar requires injection support that is not yet implemented. SQL has a built-in grammar recipe and can be installed with vorto grammar install sql, but has no built-in LSP server. Go uses tab indentation by default, matching gofmt output.

​
Installing grammars and LSP servers

Grammar recipes and LSP server configurations are independent. You need to install both separately:
1

Install the tree-sitter grammar

vorto grammar install rust
This builds the shared library and writes query files to ~/.config/vorto/. See Installing tree-sitter grammars for full details.
2

Install the LSP server binary

Install the server binary through your system’s package manager or language toolchain. For example:
# Rust
rustup component add rust-analyzer

# Python
pip install pyright

# Go
go install golang.org/x/tools/gopls@latest

# Zig
# Download zls from https://github.com/zigtools/zls/releases
The binary must be on your PATH when you start Vorto.

​
Adding custom languages

You can add support for languages not listed here by declaring a [languages.<name>] block in ~/.config/vorto/config.toml: 
[languages.mylang]
extensions = ["mlg"]
comment_token = "//"
lsp = ["my-lsp-server"]

[lsp.my-lsp-server]
command = "my-lsp"
args = ["--stdio"]
root_markers = ["myproject.json"]
You can also override any field for a built-in language. For example, to add an extra extension to Rust: 
[languages.rust]
extensions = ["rs", "rlib"]
LSP server binaries are never bundled with Vorto. You must install them separately and ensure they are available on your PATH.
