The message 1 is invalid: * The line 8 of the message (line 6 of the body) exceeds the limit of 72 characters. The line contains 78 characters: "Also set the default to '.'

Please reformat the body so that all the lines fit 72 characters. * The line 16 of the message (line 14 of the body) exceeds the limit of 72 characters. The line contains 77 characters: "file extensions (tree-sitter's language detection also uses regexps, but none". Please reformat the body so that all the lines fit 72 characters. The original message was: Implement walking of directories Recurse into directories using BurntSushi's walkdir crate. This means the following is now possible: unicop src/ Also set the default to '.' (i.e. recursively checking the current directory). I've read in the documentation that tree-sitter actually has a language-detection framework that grammars can plug into, but unfortunately, it doesn't seem to be exposed in the library. It might still be a good idea to adopt it, as it will make it easier to add new languages. This commit contains a stripped-down version that only look at file extensions (tree-sitter's language detection also uses regexps, but none of the current grammars define any.)
