# boa-unicode
|
||
|
|
|
||
|
|
`boa-unicode` defines the trait to provide methods for querying properties or classes for Unicode identifiers. These properties are used to determine if a code point (char) is valid for being the start/part of an identifier in lexer and parser.
|
||
|
|
|
||
|
|
Current version: Unicode 13.0.0
|
||
|
|
|
||
|
|
## Development
|
||
|
|
|
||
|
|
The Unicode character tables used to query properties are generated by `build_tables.js`. This script depends on [Node.js](https://nodejs.org/en/) and [rustfmt](https://github.com/rust-lang/rustfmt). You can run the script with:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ node build_tables.js
|
||
|
|
```
|
||
|
|
|
||
|
|
or with [npm](https://www.npmjs.com/):
|
||
|
|
|
||
|
|
```
|
||
|
|
$ npm run build-tables
|
||
|
|
```
|
||
|
|
|
||
|
|
The configurations are defined as constants in the script. Please check the comments in `build_tables.js` for more information.
