## expltools 2025-04-25

### explcheck v0.9.0

#### Development

- Add basic support for semantic analysis and reading (nested) function
  definitions. (#75)

  None of the issues from Section 4 of the document titled [_Warnings and errors
  for the expl3 analysis tool_][warnings-and-errors] are recognized by
  explcheck yet. Support for (some of) these issues will be added in the next
  minor release.

 [warnings-and-errors]: https://github.com/witiko/expltools/releases/download/latest/warnings-and-errors.pdf

- Add error E304 (Unexpected parameter number) for incorrect parameter tokens
  in parameter and replacement texts of function definitions. (#75)

#### Fixes

- Exclude global scratch variables from issue S206 (Malformed variable or
  constant name). (reported by @fpantigny in #76, fixed in #77)

- Do not produce warning S204 (Missing stylistic whitespaces) in Lua code.
  (reported by @zepinglee in #29, fixed in #75)

#### Documentation

- Add a link to [a work-in-progress TUG 2025 paper][expltools-tug25-paper] to
  `README.md`. (8d4177b, 99ef3b9)
