# Tools used to implement libsyntax
|
|
|
|
libsyntax uses several tools to help with development.
|
|
|
|
Each tool is a binary in the [tools/](../tools) package.
|
|
You can run them via `cargo run` command.
|
|
|
|
```
|
|
cargo run --package tools --bin tool
|
|
```
|
|
|
|
There are also aliases in [./cargo/config](../.cargo/config),
|
|
so the following also works:
|
|
|
|
```
|
|
cargo tool
|
|
```
|
|
|
|
|
|
## Tool: `gen`
|
|
|
|
This tool reads a "grammar" from [grammar.ron](../grammar.ron) and
|
|
generates the `syntax_kinds.rs` file. You should run this tool if you
|
|
add new keywords or syntax elements.
|
|
|
|
|
|
## Tool: `parse`
|
|
|
|
This tool reads rust source code from the standard input, parses it,
|
|
and prints the result to stdout.
|
|
|
|
|
|
## Tool: `collect-tests`
|
|
|
|
This tools collect inline tests from comments in libsyntax2 source code
|
|
and places them into `tests/data/inline` directory.
