boa_unicode 0.11.0

Boa is a Javascript lexer, parser and Just-in-Time compiler written in Rust. Currently, it has support for some of the language.


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


The Unicode character tables used to query properties are generated by build_tables.js. This script depends on Node.js and rustfmt. You can run the script with:

$ node build_tables.js

or with npm:

$ npm run build-tables

The configurations are defined as constants in the script. Please check the comments in build_tables.js for more information.
