CTAN update: expltools
by CTAN Announcements 01 Oct '25

01 Oct '25

Vít Starý Novotný submitted an update to the expltools bundle. Version: 2025-09-29 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: ---------------------------------------------------------------------- ## expltools 2025-09-29 ### explcheck v0.13.0 #### Fixes This version of explcheck has fixed the following bugs: - Do not deduplicate issues with the same identifier and range but different context. (#132) - Do not report issues E420 (Locally setting a global variable) and E421 (Globally setting a local variable) in top-level code. (21e2023a, 61a40cb7, cfa7847b) - Support message definitions using the deprecated function `\msg_gset:nn...`. (3101d9ff) #### Warnings and errors This version of explcheck has made the following changes to the document titled [_Warnings and errors for the expl3 analysis tool_][warnings-and-errors]: - Plan issue S105 (Needlessly ignored issue). (#130, #132) [warnings-and-errors]: https://github.com/witiko/expltools/releases/download/latest/warnings-and-e… #### Development This version of explcheck has implemented the following new features: - Support inter-file dependencies. (#129, #131) After this change, you may manually _group files_ from the command-line interface as follows: explcheck first.tex + second.tex , third.tex , fourth.tex The above command would cause the files `first.tex` and `second.tex` to be processed together and allow explcheck to assume that these files will always be used together. As a result, using e.g. a function in the file `first.tex` that is only defined in the file `second.tex` would no longer raise the error E408 (Calling an undefined function). To control how files are grouped by default, you may use the new command-line option `--group-files`. To process a group of files in Lua, you may use the function `process_files()` from the file `explcheck-utils.lua`: ``` lua local utils = require("explcheck-utils") local first_group_results = utils.process_files({"first.tex", "second.tex"}) local second_group_results = utils.process_files({"third.tex"}) local third_group_results = utils.process_files({"fourth.tex"}) ``` - Add a new command-line option `--files-from`. (#131) Use this option to read the list of expl3 files to check from a text file. - Report a warning for needlessly ignored issues. (#130, #132) Needlessly ignored issues produce warning S105 (Needlessly ignored issue). - Update the representation of segments according to [the work-in-progress TUG 2025 paper][expltools-tug25-paper]. (#128, #133) Previously, calls and statements were tied to expl3 parts, similarly to groupings and tokens, and the notion of "nested calls" and "nested statements" was tackled ad-hoc. Following this change, syntactic and semantic analyses no longer operate on expl3 parts but on segments that represent blocks of either top-level or nested code in some expl3 part from some file in the current group of files. This more general notion of a block of code that may carry calls and statements makes it possible to dynamically support new kinds of segments without changing the logic of the code. Furthermore, segments can be easily referenced regardless of their files and expl3 parts of origin, and subdivided into "chunks of well-understood code", which will be the base data type for the flow analysis. Therefore, this change lays the groundwork for the implementation of the flow analysis, where we'll be working with a directed graph with chunks as the nodes. - Recognize `T`- and `F`-type arguments as code segments. (#92, #136) This allows issues to be reported in true- and false-branches of conditional functions, even if these functions are unknown or nested. - Report code coverage in the verbose human-readable output. (#134, #135) The code coverage provides an estimate of how well-understood a piece of code is. Circa 14% of all expl3 code and 2% of all TeX code in current TeX Live is considered well-understood. The cut-off for performing the flow analysis is likely going to be circa 95% well-understood expl3 tokens, so most code will initially only be analyzed using semantic analysis, not flow analysis. #### Continuous integration This version of explcheck has made the following changes to our continuous integration: - Compare code coverage on TeX Live 2024 with a baseline. (#134, #135) This acts as an extra precaution against regressions. In general, changes should only increase the code coverage compared to the baseline. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/expltools The package’s files themselves can be inspected at https://mirrors.ctan.org/support/expltools/ ------------------------------------------------------------------------ Thanks for the upload.

Vit Starý Novotný submitted an update to the markdown package. Version number: 3.11.6-0-g340ac223 2025-09-29 License type: lppl1.3c Summary description: Converting and rendering markdown documents inside TeX Announcement text: ---------------------------------------------------------------------- Tests: - Improve the speed of our tests more by than 3×. (added by @zauguin, @muzimuzhi, @gucci-on-fleek, and @josephwright in latex3/latex3#1791, discussed in #557 and #584) - Enable LuaMetaTeX in ConTeXt tests. (added by @witiko in #557 with major contributions from @josephwright and @gucci-on-fleek in #557, latex3/latex3#1791, latex3/latex3#1797, and elsewhere) Documentation: - Add installation instructions for ConTeXt Standalone to the user manual. (reported by @andreiborisov in #402, added by @witiko and @gucci-on-fleek in #557) Continuous integration: - Do not use self-hosted runners in pull requests either. (07af69a8) - Remove TeX Live 2023 and 2024 from the continuous integration. (5cb59800) This is because we can't typeset the ConTeXt LMTX example document with earlier TeX Live versions. TeX Live 2023 and 2024 are still supported. Examples: - Add example file `examples/context-lmtx.tex` for ConTeXt LMTX. (added by @witiko in #557 with major contributions from @josephwright and @gucci-on-fleek in #557 and elsewhere) Housekeeping: - Remove needless ignored issues.
