We have multiple releases in the field under active maintenance (plus th= e next release under development). I have cron jobs that make TAGS daily (= overnight) because it takes hours to read the entire source in the multiple= release source branches. Each TAGS file per branch is over 40MB. I run a= n instance of Emacs per release branch, because we use ClearCase, so the "s= ame file name" potentially has different contents depending on the view (i.= e., can't use Emacs Server across releases). When I want to use tag completion, it takes about a minute for Emacs to con= struct the completion table. Meanwhile, I can't do anything else in Emacs.= I'm wondering if it's possible to get the completion table pre-loaded in = the background, so when I am finding a tag and hit '?' I get an instantaneo= us response the first time, instead of a minute-long wait. For context, I have been using EMACS/Emacs for over 30 years and my .emacs = file is tiny, only pointing to another file with the real customization. M= y customization is ~1,000 lines, and I byte-compile it. I like pretending = my name is Luke and using the source, but could use some tips and pointers = about whether it's a good idea to try this in the background. I'm not even= sure it's possible to run this in the background (asynchronously). Does E= macs have such asynchronous execution capability? If asynchronous execution isn't possible or wise, I'll settle for a way to = forcibly load the completion table (without my needing to manually trigger = it). I don't see a way to do that, either. Thanks in advance! Mark P.S. If there is a better e-mail list for this question, please let me know= .
