v0.10.1

This release lets the PyPI package install the texform command-line tool, and fixes transform failures and output that did not reparse, mostly with physics. One rule key changes; see Changed.

Changed

• The rule key base/operatorname-to-named-function becomes ams/operatorname-to-named-function, because the rule only applies when ams provides \operatorname. Configurations that enable or disable the old key must use the new one; the old key is not kept as an alias. Output is unchanged.

Added

• The PyPI package installs the texform command, also available as python -m texform, so the command-line tool no longer needs a Rust toolchain. Install it with uv tool install texform, or run it once with uvx texform. It runs the same code as cargo install texform-cli, with the same commands, output, and exit statuses; each invocation adds about 10 ms of Python startup, and --lines and serve throughput is unchanged.

Fixed

• With physics, \eval, \eval*, and \evaluated without a following (, [, or brace group no longer fail with a rewrite contract violation. As in MathJax, they expand to \left.\vphantom{\int}\right|, so \eval x becomes \left.\vphantom{\int}\right| x.
• With physics, an ordered derivative whose variable already has a superscript no longer produces a double superscript that fails to reparse: \dv[2]{f}{x^2} now gives \mathrm{d}{x^{2}}^{2} in the denominator. \pdv and \fdv are fixed the same way.
• A delimited argument whose content ends with an unpaired copy of its opening delimiter is kept in a protective brace group, and the parser strips that group again. Under Equiv with physics, \qty(a{\big(}b) now becomes \qty({a(b}) instead of \qty(a(b), which failed to parse.
• Rewriting a scripted \break or \newline attaches its scripts to an empty base, so \break' becomes \\{}', and FlattenGroups keeps the group in {\cr}_1. Both outputs previously changed when parsed again.
• Dropping \goodbreak used as a script base no longer panics in Corpus and lower profiles: \goodbreak^2 becomes {}^{2}.
