# Rust Analyzer
[](https://travis-ci.org/rust-analyzer/rust-analyzer)
Rust Analyzer is an **experimental** modular compiler frontend for the Rust
language. It is a part of a larger rls-2.0 effort to create excellent IDE
support for Rust. If you want to get involved, check the rls-2.0 working group
in the compiler-team repository:
https://github.com/rust-lang/compiler-team/tree/master/working-groups/rls-2.0
Work on the Rust Analyzer is sponsored by
[](https://ferrous-systems.com/)
## Quick Start
Rust analyzer builds on Rust >= 1.31.0 and uses the 2018 edition.
```
# run tests
$ cargo test
# show syntax tree of a Rust file
$ cargo run --package ra_cli parse < crates/ra_syntax/src/lib.rs
# show symbols of a Rust file
$ cargo run --package ra_cli symbols < crates/ra_syntax/src/lib.rs
# install the language server
$ cargo install-lsp
or
$ cargo install --path crates/ra_lsp_server
```
See [these instructions](./editors/README.md) for VS Code setup and the list of
features (some of which are VS Code specific).
## Debugging
See [these instructions](./DEBUGGING.md) on how to debug the vscode extension and the lsp server.
## Getting in touch
We are on the rust-lang Zulip!
