To accept these unrecognized words as correct and remove the previously acknowledged and now absent words, you could run the following commands

... in a clone of the [git@github.com:Joker2770/Sanmill.git](https://github.com/Joker2770/Sanmill.git) repository on the `xmake-patch` branch ([:information_source: how do I use this?]( https://github.com/check-spelling/check-spelling/wiki/Accepting-Suggestions)): ``` sh curl -s -S -L 'https://raw.githubusercontent.com/check-spelling/check-spelling/main/apply.pl' | perl - 'https://github.com/calcitem/Sanmill/actions/runs/10053316442/attempts/1' ```

If the flagged items are :exploding_head: false positives

If items relate to a ... * binary file (or some other file you wouldn't want to check at all). Please add a file path to the `excludes.txt` file matching the containing file. File paths are Perl 5 Regular Expressions - you can [test]( https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your files. `^` refers to the file's path from the root of the repository, so `^README\.md$` would exclude [README.md]( ../tree/HEAD/README.md) (on whichever branch you're using). * well-formed pattern. If you can write a [pattern](https://github.com/check-spelling/check-spelling/wiki/Configuration-Examples:-patterns) that would match it, try adding it to the `patterns.txt` file. Patterns are Perl 5 Regular Expressions - you can [test]( https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your lines. Note that patterns can't match multiline strings.
