New on CTAN: physics3
by CTAN Announcements via ctan-ann 28 Jan '26

28 Jan '26

Mingyu Xia submitted the physics3 package. Version number: 0.1A 2026-01-26 License type: lppl1.3c Summary description: Modularized package for easy setting of physical formulas Announcement text: ---------------------------------------------------------------------- - Apart from the legacy `physics` package, this package has solved the abuse of tokens: in the legacy `physics` package, if one writes over 32767 (= 2^{15}-1) matrix commands (although nobody will do this, but it’s a potential risk), then the compiler will crash due to the limitation of memory. Also, the legacy `physics` package used a lot of `g`-argument in xparse of the LaTeX kernel, which is officially not suggested by the LaTeX team. - This package also provides a simple way to typeset the inner product (norm) and outer product (projector) formulas: \bknorm[<size>, basis]{<operator>}, \kbproj[<size>]{<basis>} - Different from another package, `physics2`, this package has optimized the matrix commands: a simple way for inputting a small diagonal matrix (based on the smallmatrix environment in `mathtools` package) is provided: \diagmat*{a, b, c} The star (*) after the `\diagmat` command determines if the output matrix is small. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/physics3 More information is at https://www.ctan.org/pkg/physics3 ------------------------------------------------------------------------ Thanks for the upload.

To enable it, set the Lua option `stop_after = "flow analysis"` > either in your Lua code or your configuration file. > > After this change, you may already see preliminary flow analysis results in > explcheck's verbose output. However, unless explcheck understands your file > sufficiently well, it will typically stop before reaching the flow analysis > step and will report this in the verbose output. > > If explcheck reaches semantic analysis, you can encourage it to proceed to > flow analysis by decreasing the Lua option `min_code_coverage` towards zero. > If explcheck bails out earlier, try disabling `stop_early_when_confused` or, > ideally, improve your code quality and contribute to expltools so that it can > understand your code better. 😉 > > - In the syntactic analysis, fix the assignment of segment numbers to `T`- and > `F`-type arguments.
