So…
There I was, working on our mail server and it was off for a couple of minutes.
Restarted, went back to Apple Mail, and all my messages were piling up in my Inbox.
But I have rules for all these messages!
Open the mail rules and they’re all unchecked!?
WTF
Seems that if Mail tries to run a move rule, and the target mailbox isn’t available, it helpfully (?!?) unchecks it.
Thing is, there’s no easy way to deal with a group of rules; the rules interface in Apple Mail sucks, pure and simple.
So, I went looking for the .plist and found it at:
mate ~/Library/Mail/MessageRules.plist
Finding a regular expression that would allow me to replace the following was a little trickier:
<dict> <key>rules</key> <array> <dict> <key>Active</key> <string>1</string> and so on...
So, basically, each rule has a dict, with various pieces of stuff in them, one of which is the flag that tells whether the rule is active. Unfortunately, it’s not all stored in one tag, so the search has to include the <key>Active</key> plus the newline, plus the following <string> tag.
A quick regular expression handles that just fine:
(<key>Active</key>\n.*<string>)0(</string>)
Two captures (inside the parenthesis) allow you to use the matched text in the replacement. The problem comes in when you try to use the obvious replacement expression:
$11$0
Unfortunately, TextMate (and all normal regexp engines) try to find the match $11, when what you mean is “match $1 followed by a 1 character.”
Rather than bore you with the details, the solution is this:
$1(?0:)1$2
That fixes it right up by using a dummy placeholder (?0:) that always evaluates to nothing, but keeps things straight that we mean $1.
Just for reference, I found this at: A cached google page from ‘Old Nabble’ Since it might be long gone, I’ve duplicated the text here:
Search & replace regex question

Hi everybody!
Is there (in TextMate’s built-in search) a solution for forming a replace string for a variable directly followed by a number, ie. $15 (read: $1 and 5, without a space in between)?
Can this somehow be done or is reformulating the search string the only way in such a case?
Thanks!
Chris

Maybe you could try to use Conditional Insertions mentioned in the TM
manual chapter 20.4.3
http://manual.macromates.com/en/regular_expressions
Naïve example:
I have the string
123456
and I want to get
123457
by using this regexp:
123(.)(.)7
this won’t work:
123$1$27 because $27 isn’t set
but this should work
123$1$2(?0:)7
(?0:) is a kind of dummy and inserts nothing
Cheers,
–Hans

Good idea, thanks! I didn’t know that …
