CTAN update: expltools
by CTAN Announcements 26 Nov '25

26 Nov '25

Vít Starý Novotný submitted an update to the expltools package. Version: 2025-11-24 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: ---------------------------------------------------------------------- ## expltools 2025-11-24 ### explcheck v0.16.0 #### Development This version of explcheck has implemented the following new features: - Support specifying cut-off dates for deprecations from the file `l3obsolete.txt` and prefixes from the file `l3prefixes.csv`. (suggested by @YDX-2147483647 in #147 and #149, added in #150) For example, here is how your config file `.explcheckrc` might look if you would like to only take into account the deprecations and prefixes from TeX Live 2024 and earlier: ``` toml [defaults] l3obsolete_max_deprecated_date = "2024-03-30" l3prefixes_max_first_registered_date = "2024-11-18" ``` You may get these dates by running the script `generate-explcheck-latex3.lua` with files `l3obsolete.txt` and `l3prefixes.csv` from TeX Live 2024 placed in the current working directory or other locations indexed by the KPathSea library. Here is the output of the script: ``` LPEG parsers and other information extracted from LaTeX3 data files. Generated on 2025-11-06 from the following files: - "l3obsolete.txt" with the latest obsolete entry from 2024-03-30 - "l3prefixes.csv" with the latest registered prefix from 2024-11-18 ``` You may also just use the dates of the last update to TeX Live 2024 (2025-03-09) for both options, see https://tug.org/historic, directory `systems/texlive/2024/tlnet-final`. #### Fixes This version of explcheck has fixed the following bugs: - Fix an attempt to index a nil value in function `count_segments()` from the file `explcheck-evaluation.lua`. (#150) This bug would surface when printing results for files whose processing stopped before the syntactic analysis step. #### Continuous integration This version of explcheck has made the following changes to our continuous integration: - Use historic files "l3obsolete.txt" and "l3prefixes.csv" in CI. (#150) - Include example files from the `doc` subtree in regression tests. (#150) This has reduced code coverage from ca 24% to 21% of all expl3 tokens on TeX Live 2024 and from ca 22% to 20% on current TeX Live 2025 (2025-11-06). - Check if the configuration is minimal even for expl3 files without any issues. (#150) This is necessary to prevent incorrect recommendations to remove unnecessary default settings from the file `.explcheckrc` in the script `prune-explcheck-config.lua`. - Bump actions/checkout from 5 to 6.

Nicola Talbot submitted an update to the flowfram package. Version: 2.0 2025-11-24 License: lppl1.3 Summary description: Create text frames for posters, brochures or magazines Announcement text: ---------------------------------------------------------------------- Version 2.0 has been mostly rewritten using LaTeX3 commands and updated to take into account changes to the output routine in the LaTeX kernel. Some defaults have changed. If there are any compatibility issues you can rollback to v1.18 or v1.17. New supplementary package flowframtkutils.sty included for use with FlowframTk (distributed separately).
