.hgignore website refresh files

My ASP.NET website references refresh files that are being excluded because they reside in the ...\bin\ directory of projects.

What can I add to my .hgignore file to ensure just the ...\bin\*.refresh files are NOT excluded?

Note: I understand I could use hg add ...\bin\my.dll.refresh for each of the references and continue with my .hgignore, but I'd like to avoid needing to manually add specific files types as this is error prone and easy to forget.

Solution

For "all except some names" you must use:

regexp pattern
add negative lookahead in regexp "all files"(get "all except in this subset" as result)

syntax: regexp

bin/(?!.*\.refresh$).+

in any case, check and debug this expression, using filenames with pattern bin\*.*refresh* and hg status command
