I want to use this pattern in my .hgignore:
syntax: regexp
(?<![^/])\.(?!(idea|yarn)/)
i.e. match all files/directories starting with a . other than the .idea/ and .yarn/ directories.
However, when I run hg status -n --color=no, my .idea files aren't listed.
If I change that last / to \b then I get:
.idea/blade.xml
.idea/codeStyleSettings.xml
.idea/codeStyles/Project.xml
.idea/codeStyles/codeStyleConfig.xml
.idea/copyright/profiles_settings.xml
\b is probably close enough to what I want, but I can't understand why it won't work with . when the status list clearly shows files with .idea/.
Regex101 also shows that it should work.
Match (note the "x"):
Doesn't match (as intended, because it's negated):
