This PR implements the
ignoreFile
option and rewrites theignore
option behaviour. Previously, we usedglob
'signore
option to pass an array of ignore rules to the library. This meant we'd get back a set of filtered files where ignore rules were already applied. However,glob
does not support negated ignore rules, meaning ignore patterns like "ignore everything except file x" wouldn't work.With this PR, we introduce a new library to the project: ignore. It lets us add rules to a rule checker (regardless of if these rules come from a file or an array). We now first collect all files with
glob
and subsequently filter out the ones that are ignored by the specified ignore rules. This rule checker supports all rules as specified in.gitignore
specs. Therefore, it also supports negated ignore rules.ref: #62
