I’m still using TextMate 1, since 2.0 has been buggy for me. If you’re in the same boat, you might share my frustration with the recurring lag that TextMate experiences when switching focus between applications. TextMate tries to reload the entire project’s file state on focus, and this can be noticeably slow.
These tips have eliminated the problem for me. Feel free to mix and match:
Avoid loading the entire project directory
If you’re working with a Rails project, you can avoid loading the heavy
tmp/ directories with the
mater alias. Just put this in one of your shell start-up scripts:
alias mater="ls | grep -Ev 'log|tmp' | xargs mate"
Adjust for other project types.
Disable project tree refresh with ReMate
The ReMate plugin adds a Disable Refresh on Regaining Focus item to the Window menu. Download and extract the plugin, double click to add to TextMate, and relaunch TextMate. Then, check the new menu option to disable the project refresh behavior entirely. (You can always temporarily uncheck it to refresh the project state.)
