Extract JavaScript UI framework functionality into dedicated testdrive-jsui capability while maintaining 100% functionality preservation and integrating JavaScript tests into the main Python test suite. Phase 1 (Foundation Setup) - COMPLETED: - Created capability directory structure with proper Python package layout - Configured pyproject.toml with Node.js subprocess dependencies - Set up package.json with Jest + JSDOM testing framework - Implemented Python-JavaScript bridge for seamless test integration - Created comprehensive capability Makefile with all testing targets - Added detailed README documentation for capability usage Phase 2 (Integration Layer) - COMPLETED: - Built Python test wrappers for JavaScript test execution via subprocess - Integrated with pytest discovery system for unified test experience - Added capability targets to main Makefile delegation system - Verified test integration works with main test suite Phase 3 (Safe Migration) - COMPLETED: - Copied (not moved) all JavaScript files to capability using safe copy-first approach - Migrated 4 core JavaScript components and 11 test files (2,840+ lines) - Verified all tests work in new location (11 Python tests + 7 JavaScript tests passing) - Maintained dual-track testing capability for safety during transition Phase 4 (Framework Enhancement) - COMPLETED: - Enhanced testing framework with Python integration and coverage reporting - Achieved 59% Python test coverage and 100% JavaScript test coverage - Added performance benchmarking and component documentation Phase 5 (Production Integration) - COMPLETED: - Added standard 'test' target to capability Makefile for discovery system compatibility - Integrated JavaScript tests into main Makefile with new targets: * test-js: Run JavaScript UI tests * test-all: Run all tests (Python + JavaScript + Capabilities) - Updated help documentation to include new testing workflows - Verified capability auto-discovery works via 'make test-capabilities' Key Achievements: - Zero-risk migration completed with copy-first safety approach - Full Python-JavaScript test integration with 18 total passing tests - JavaScript UI framework successfully extracted to dedicated capability - Enhanced CI/CD integration with unified test command interface - Clean architecture enabling future JavaScript framework evolution Testing Status: - ✅ All Python integration tests passing (11/11) - ✅ All JavaScript component tests passing (7/7) - ✅ Capability discovery integration working - ✅ Main test suite integration complete - ✅ Test coverage reporting functional (59% Python, 100% JavaScript) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Implemented from : https://www.w3.org/TR/2021/CRD-css-syntax-3-20211224/
|
|
|
|
## API
|
|
|
|
[Read the API docs](./docs/css-tokenizer.md)
|
|
|
|
## Usage
|
|
|
|
Add [CSS Tokenizer] to your project:
|
|
|
|
```bash
|
|
npm install @csstools/css-tokenizer --save-dev
|
|
```
|
|
|
|
```js
|
|
import { tokenizer, TokenType } from '@csstools/css-tokenizer';
|
|
|
|
const myCSS = `@media only screen and (min-width: 768rem) {
|
|
.foo {
|
|
content: 'Some content!' !important;
|
|
}
|
|
}
|
|
`;
|
|
|
|
const t = tokenizer({
|
|
css: myCSS,
|
|
});
|
|
|
|
while (true) {
|
|
const token = t.nextToken();
|
|
if (token[0] === TokenType.EOF) {
|
|
break;
|
|
}
|
|
|
|
console.log(token);
|
|
}
|
|
```
|
|
|
|
Or use the `tokenize` helper function:
|
|
|
|
```js
|
|
import { tokenize } from '@csstools/css-tokenizer';
|
|
|
|
const myCSS = `@media only screen and (min-width: 768rem) {
|
|
.foo {
|
|
content: 'Some content!' !important;
|
|
}
|
|
}
|
|
`;
|
|
|
|
const tokens = tokenize({
|
|
css: myCSS,
|
|
});
|
|
|
|
console.log(tokens);
|
|
```
|
|
|
|
### Options
|
|
|
|
```ts
|
|
{
|
|
onParseError?: (error: ParseError) => void
|
|
}
|
|
```
|
|
|
|
#### `onParseError`
|
|
|
|
The tokenizer is forgiving and won't stop when a parse error is encountered.
|
|
|
|
To receive parsing error information you can set a callback.
|
|
|
|
```js
|
|
import { tokenizer, TokenType } from '@csstools/css-tokenizer';
|
|
|
|
const t = tokenizer({
|
|
css: '\\',
|
|
}, { onParseError: (err) => console.warn(err) });
|
|
|
|
while (true) {
|
|
const token = t.nextToken();
|
|
if (token[0] === TokenType.EOF) {
|
|
break;
|
|
}
|
|
}
|
|
```
|
|
|
|
Parser errors will try to inform you where in the tokenizer logic the error happened.
|
|
This tells you what kind of error occurred.
|
|
|
|
## Goals and non-goals
|
|
|
|
Things this package aims to be:
|
|
- specification compliant CSS tokenizer
|
|
- a reliable low level package to be used in CSS parsers
|
|
|
|
What it is not:
|
|
- opinionated
|
|
- fast
|
|
- small
