I often have a build log file open in Sublime when compiling an embedded project. The file is re-written on each re-compile, but I’ve noticed that when I use the Find option and have the regex mode enabled to search for “Errors: [1-9]” pattern. I have noticed that the regex find option gets disabled (although visually it still shows as enabled) after the file has been re-created and sublime automatically reloads the updated file.
Manually clicking to disable and then re-enable the regex option in the find bar fixes things, but without doing this clicking find does not give results since (I assume) it is looking for a literal match instead of a regex match.
This issue is present in the 4113 build of Sublime Text. I have most often seen this on Windows 10 as that is the platform I am currently using the most, but I have seen it as well on Ubuntu Linux as well.
