MegaLinter generates content of a .cspell.json config file at the end of its TextReporter artifact

Copy it at the root of your repository, read it, remove real spelling errors (after have corrected them in the source), and you're good to go !

If you do not want cspell to analyze the files names, define SPELL_CSPELL_ANALYZE_FILE_NAMES to false

Behind the scenes

How are identified applicable files

  • If this linter is active, all files linted by all other active linters will be linted

How the linting is performed

  • cspell is called once with the list of files as arguments (list_of_files CLI lint mode)

Example calls

cspell myfile.any
cspell -c cspell.json myfile.any
