[TxMt] Annoying slowdowns of textmate...

[Andrew Farley]

Hey guys,

First, I have a few very large projects with upwards of 100K files  
(mostly images and .svn files...) and I run into two problems because  
of it.  And no, I do not have the folder tabs open that have the  
majority of these files.  I have those folder tabs closed, because  
they are all not really editable by textmate, ever.

So, first, I regularly background and foreground TextMate, and every  
time I do so with this "folder" open in a TextMate window, it takes  
anywhere from 2 to 20 seconds to re-foreground.  I'm one of those  
really really fast users who makes a change, switches to browser, hits  
refresh, goes back, makes a change, etc. etc.  Pretty standard with  
web development.  This delay (especially when it leans towards the  
longer end) is really unbearable.  I have a feeling that it is re- 
scanning the entire directory tree for changes everytime I background/ 
foreground it.  This is less than ideal.  I've been to a few Leopard  
dev talks at the last WWDC and I remember a feature (can't remember  
the name) that let you subscribe to folder/file changes.  Perhaps  
TextMate should do this instead of rescanning the directory tree for  
changes?  Or, maybe it's not doing that... but something is happening  
which makes it take up to around 20 (sometimes rarely even 30-40)  
seconds everytime I foreground textmate with this folder open.   
Anything I can do about this?

Second, I regularly "find in files" in textmate.  And with 100K files,  
PHEW this takes sometimes a minute or two to finish.  Is there any way  
to specify a file filter to search through?  (eg. only search  
through .php, .txt, .tpl and .lib files).  If not, can this feature  
exist please?  :\  TextMate is searching my folder(s) through huge SQL  
dumps which are useless to me.  And/or is there any way to specify a  
"blacklist" of file extensions/types to NOT search through?  Even if  
this is a hardcoded list in a plist somewhere, that would work for me  
for now, anything to reduce the time on my searches.  Any ideas?

Cheers,

Andrew

P.S.  This is all on a brand new unibody MacBook with 4G of RAM and  
320GB 72K RPM drive... so I'm not low on ram or anything.  :)
