Summary description: Development tools for expl3 programmers
Announcement text:
## expltools 2026-04-13 ### explcheck v0.19.2 #### Fixes This version of explcheck has fixed the following problems: - Recognize `\prop_new_linked:N` as a variable declaration statement and `\prop_const_from_keyval:Nn`, `\prop_const_linked_from_keyval:Nn`, `\prop_set_from_keyval:Nn`, and `\prop_gset_from_keyval:Nn` as constant and variable definition statements. (reported by @muzimuzhi in #196, fixed in #198) More generally, this change also adds support for constant definitions in the form `\⟨type⟩_const_from_⟨base_type⟩:*`. This improves [code coverage][] by 37,759 expl3 tokens (~0.004% of all expl3 tokens) on TeX Live 2026. - Correctly differentiate between direct and indirect variable and constant definitions in the form `\⟨type⟩_(set|gset|const)_from_⟨base_type⟩:*`. (#198) - Only report issues E504 (Function variant for an undefined function), E506 (Indirect function definition from an undefined function), and W507 (Setting a function before definition) for top-level reachable segments. (reported by @muzimuzhi in #195, fixed in #198) - Do not report issue E505 (Calling an undefined function) for indirect definitions that resolve to well-known control sequence names. (reported by @muzimuzhi in #197, fixed in #198) [code coverage]: https://witiko.github.io/Expl3-Linter-11/#code-coverage #### Continuous integration This version of explcheck has made the following changes to our continuous integration: - Update the `zauguin/install-texlive` action to v4.3. (484989a) - Retry `tlmgr install` and `update`. (#198)

expltools – Development tools for expl3 programmers
This bundle introduces explcheck, a static analysis tool for developers working with expl3 code. Currently in its initial release, explcheck aims to help developers identify potential issues and improve code quality. In the future, this bundle may expand to include additional development tools for expl3.
