Summary description: Extension for documenting LaTeX source files
Announcement text: ------------------------------------------------------------------------
## Version 0.2E:
- `codemo` now cooperates with the LaTeX tagging project. With `\DocumentMetadata{tagging=on}` the code panel is tagged as code, the result panel as a text block, and the surrounding frames are artifacts. The manual itself is typeset with tagging enabled and loads `latex-lab-testphase-l3doc` for the `l3doc` class. - The result panel of `codemo` keeps its full width when the demo body is a single vertical box, such as a display-like environment (`CJKfilltwosides` in `LuaCJK`). A panel is a `\parbox` and takes its width from its content, so the body starts by leaving vertical mode. - `codemo` works in the `article` class again. The panel widths are arithmetic expressions, and `\setlength` understands the subtraction only with `calc` loaded, which `l3doc` provides and `article` does not; both widths are now evaluated with `\dim_eval:n`. - `testfiles/codemo01.lvt` compares the panel width of a text body with that of a one-box body, on all four engines; `testfiles/tagging01.lvt` checks `codemo` with tagging enabled where the engine supports it.
## Version 0.2F:
- Fix the `keyval` label alignment in tagged documents. The tagging emulation of `enumitem` does not compute enumitem's widest label, so `keyval` now pins `labelwidth` to `\marginparwidth`, the width `\keys` already scales against, and hangs the label left by the same amount. The `=` signs stay in one column in tagged and untagged documents. - Add `testfiles/keyval01.lvt`, which checks the `=` column when the list is tagged. - `codemo` now cooperates with the LaTeX tagging project. With `\DocumentMetadata{tagging=on}` the code panel is tagged as code, the result panel as a text block, and the surrounding frames are artifacts. The manual itself is typeset with tagging enabled and loads `latex-lab-testphase-l3doc` for the `l3doc` class. - The result panel of `codemo` keeps its full width when the demo body is a single vertical box, such as a display-like environment (`CJKfilltwosides` in `LuaCJK`).
