chore(text area): prepare for tree-sitter breaking changes #5965
Conversation
Temporarily install tree-sitter from GitHub to test against breaking changes before v0.25.0 is released on PyPI.
Fix breaking change in tree-sitter v0.25.0 where `Query.captures` has been moved to `QueryCursor.captures`. Related PR: tree-sitter/py-tree-sitter#333

This might have revealed a possible bug in the current Python syntax highlighting. It looks like any variables are currently being highlighted as |
`lua-match` is specific to tree-sitter in Neovim. Currently these query predicates are ignored so highlight much more they should!

This actually revealed another bug, where the query predicates were being ignored so highlighting much more they should! After the fix in b85d4f3, the failing snapshots look much better: https://github.com/Textualize/textual/actions/runs/16349424666/artifacts/3556076660 |

Perhaps time to drop support for Python 3.8 - it's been end-of-life for a long time now.
