# Contributing
|
||||
|
||||
Thank you to contribute `tree-sitter-scheme`.
|
||||
|
||||
## Workflow
|
||||
|
||||
It's recommended to use [nix](https://nixos.org/) package manager, and run
|
||||
|
||||
```shell
|
||||
nix-shell
|
||||
npm install # if you haven't install node modules
|
||||
```
|
||||
|
||||
Then you can use `tree-sitter` command:
|
||||
|
||||
```shell
|
||||
tree-sitter generate
|
||||
tree-sitter test
|
||||
```
|
||||
|
||||
If you dont't use nix, you should follow the [official setup](https://tree-sitter.github.io/tree-sitter/creating-parsers) to configure the dev environment.
|
||||
|
||||
## Todo
|
||||
|
||||
* check the tracking issues
|
||||
* review the code to ensure it meets the standard
|
||||
* improve queries

# tree-sitter-scheme
|
||||
|
||||
[](https://github.com/6cdh/tree-sitter-scheme/actions/workflows/test.yml)
|
||||
|
||||
Scheme grammar for tree-sitter.
|
||||
|
||||
## Recent News
|
||||
|
||||
* With R7RS support, a single `|` can no longer appears in the middle of an identifier.
|
||||
* The nodes `directive` no longer contain sub nodes `symbol`. Now it's a single node.
|
||||
* some extensions added, see below
|
||||
|
||||
## Status
|
||||
|
||||
~~tree-sitter-scheme should work on a superset of Scheme.~~
|
||||
|
||||
Different Implementations might have conflict grammar. I am not sure if I should support
|
||||
them. If you need some implementation-specific features, please open an issue, then I will consider support it.
|
||||
|
||||
current status:
|
||||
|
||||
* [x] R5RS
|
||||
* [x] R6RS
|
||||
* [x] R7RS
|
||||
* [ ] Extensions
|
||||
* [x] `{}` as replacement for `()` or `[]`
|
||||
* [x] extend symbols which can start with digits, period, ... etc as long as it's not a number
|
||||
* [x] keyword `#:symbol`
|
||||
* [x] escape sequence in string `\` + any character
|
||||
* [x] characters `#\bel`, `#\ls`, `#\nel`, `#\rubout`, `#\vt`
|
||||
|
||||
Please open an issue to let me know it's really used if you want to add new extensions.
|
||||
|
||||
## Implementation
|
||||
|
||||
* [ ] Support for implementation
|
||||
* [ ] Chez Scheme ([#1](https://github.com/6cdh/tree-sitter-scheme/issues/1))
|
||||
* [ ] Chicken Scheme ([#3](https://github.com/6cdh/tree-sitter-scheme/issues/3))
|
||||
* [ ] Guile Scheme ([#7](https://github.com/6cdh/tree-sitter-scheme/issues/7))
|
||||
|
||||
## Usage
|
||||
|
||||
See [nodes.md](./nodes.md) for all visible nodes.
|
||||
|
||||
This parser don't parse language constructs. Instead, it parse code as lists.
|
||||
|
||||
If you want language constructs support, use custom queries (see [#5](https://github.com/6cdh/tree-sitter-scheme/issues/5)), also see [thchha/tree-sitter-scheme](https://gitlab.com/thchha/tree-sitter-scheme).
|
||||
|
||||
## Query
|
||||
|
||||
The queries here are too simple and not intended to be useful in an editor.
|
||||
Please open an issue if you have suggestions.
