115150 - LXR regexp searching is limited by glimpse constraints

Status: RESOLVED FIXED

(Webtools Graveyard :: MXR, defect)

Description

[Simon Fraser [no longer active]]

I'm having zero luck finding things with an lxr regexp search, like:

PRBool[\t ]+m[A-Z]

Did someone break this?

http://lxr.mozilla.org/nspr/search?string=%7B+%22AA%5BBA%5DA&regexp=on
works.

I'm guessing that each of:
+
?
\t
are broken.

* works, so for now, you can work around +.
http://lxr.mozilla.org/nspr/search?string=PRBool++*m%5BA-Z%5D&regexp=on

hah, there's documentation
please see http://lxr.mozilla.org/nspr/search-help.html esp the section on:
Regular expressions
_Currently '+' is not supported._

? isn't even listed, so you can forget about it being supported...

that leaves the fact that i can't convince \t to work.
http://lxr.mozilla.org/nspr/search?string=%5Ct%5Ct*%5BA-Z%5D&regexp=on <- 
searching for 't' :-(
http://lxr.mozilla.org/nspr/search?string=%5C%5C%5Ct%5C%5C%5Ct*%5BA-Z%5D&regexp
=on <- searching for '\'.'t' :-(
http://lxr.mozilla.org/nspr/search?string=%5C%5Ct%5C%5Ct*%5BA-Z%5D&regexp=on
<- searching for '\'.'t' :-(

offhand, i don't remember ever having \t work.

this works [for some definition of works]:
http://lxr.mozilla.org/seamonkey/search?string=PRBool++*m%5BA-Z%5D&regexp=on
Too many hits, displaying first 1000

PRBool  *m[A-Z] <- note that there's another bug here. we don't use &nbsp; or 
<pre> so the browser helpfully collapses the two spaces. I'll make sure that 
bit is fixed.

Not a mac classic issue.

Comment 4

[Dave Miller [:justdave]]

reassigning endico's bugs to default owner

Comment 5

[Chase Phillips]

Mass reassign of open bugs for [e-mail] to [e-mail].

Comment 6

[J. Paul Reed [:preed]]

Reassigning all LXR bugs assigned to [e-mail] to the default LXR owner (sorry Bear!)

We aren't actively working on these (if that's wrong, please reassign to yourself/a real person).

Simon, so mxr now enables you do what you want by using the filter field.

http://mxr.mozilla.org/seamonkey/search?string=PRBool++*m[A-Z]&regexp=1&filter=PRBool[\t+]%2Bm[A-Z]

This is underdocumented, but basically the filter field allows you to use perl regular expressions so as long as you can construct some search which is a bit broad using glimpse terms you can then narrow it to what you actually want.

I understand this isn't ideal, and I think mxr can sometimes suggest you switch to using filter, and in some cases it will actually switch things for you.
