HTML issues | Refactors | Interesting Patches | Broader Roadmap

Testing code

• HTML API: Add local testing bootstraps. wordpress-develop#6044 Add this to run HTML API tests locally without any complicated setup.
• HTML API: Run coverage tests against full HTML API wordpress-develop#6050 Generate coverage reports for the HTML API.
• HTML API: Add debug methods for inspecting internal state. wordpress-develop#6121 Adds debug methods to pretty-print internal state to the console.

Benchmarking code

• HTML API: Benchmark performance against list of domains. wordpress-develop#6049 Compare runtime performance of HTML Processor against Tag Processor

Tools built with the HTML API

• HTML API: ANSI-terminal HTML highlighter. wordpress-develop#6045 HTML syntax-highlighter and formatter.
• HTML API: List all tokens in an input document. wordpress-develop#6046 Print a diagnostics view of an HTML document, listing every token in order.
• HTML API: Inspect list of breadcrumbs for every element in a document. wordpress-develop#6051 Print a diagnostics view of an HTML document, showing breadcrumb structure and attribute preview, and whether the document is fully-supported.
• HTML API: Render an HTML document to an ANSI terminal, formatted. wordpress-develop#6047 Render HTML in a terminal-friendly way.
• HTML API: Search HTML text using a regexp & print the containing HTML. wordpress-develop#6048 Search HTML with a regex, show containing HTML for results.

Other

• HTML API: Prototype a JS port of the Tag Processor for testing purposes. wordpress-develop#6052 Rough JS port of the Tag Processor for basic performance comparisons of PHP against "something that should be faster"
• https://gist.github.com/dmsnell/11db00126a1c039cc5cb4f34f0d83ef4 Rough C port of the Tag Processor for performance estimation of "how fast could this reasonably be if included inside PHP?"
