Case insensitivity for a group has wrong effect.

Recommended Posts

martin

I want to replace a parameter in a function and I have tried doing it like this

;the string to change
$str1 = "$gui = GUICreate($OETitle, $GuiWid, $GuiHt, $moepos[0], $moepos[1])"

;Change the 4th parameter
$res2 = StringRegExpReplace($str1,"(\$gui\s*=\s*GUICreate\([^,]*,[^,]*,[^,]*,)([^,]*,)(.*)","$1 800,$3")
ConsoleWrite("Result 1 >" & $res2 & @CRLF);works as I want but only in case is correct

;same change but set case insensitivity for first group
$res2 = StringRegExpReplace($str1,"(?i\$gui\s*=\s*GUICreate\([^,]*,[^,]*,[^,]*,)([^,]*,)(.*)","$1+800,$3");(?i:$gui\s*=\s*guicreate)")
ConsoleWrite("Result 2 >" & $res2 & @CRLF);doesn't work for case insensitivity in first group

I get this result

Result 1 >$gui = GUICreate($OETitle, $GuiWid, $GuiHt, 800, $moepos[1]);<-------understood
Result 2 >$gui = GUICreate($OETitle, $GuiWid, $GuiHt, $moepos[0], $moepos[1]);<-------I don't understand

Am I doing something wrong, misunderstanding the help or does case insensitivity for a group not behave the way it should?

Are you trying to make it case sensitive, or not sensitive?

Edit01: Added below.

Edit02: Changed [autotit] to [autoit ]

Edit03: Changed case of 'g' and it still matches

Try

$res2 = StringRegExpReplace($str1,"(?i)(\$gui\s*=\s*gUICreate\([^,]*,[^,]*,[^,]*,)([^,]*,)(.*)","$1+800,$3");(?i:$gui\s*=\s*guicreate)")

Hope this helps,

Jarvis

No, I'm trying to do case insensitive. From the help

post-3602-12501132362595_thumb.png

It's true I could use (?i) to make the comparison case insenitive from there on, thanks for that. But I would like to understand how I could make one group case insensitive and, as far as I can understand it, it doesn't behave correctly, ie not as the help describes.

Well the only thing you were missing is a space. Try the following line.

$res2 = StringRegExpReplace($str1,"(?i \$gui\s*=\s*gUICreate\([^,]*,[^,]*,[^,]*,)([^,]*,)(.*)","$1+800,$3");(?i:$gui\s*=\s*guicreate)")

I hope that does it for you,

Thanks for your effort here Jarvis. Unfortunately it makes no difference. I tried the production and Beta versions.

What does it output for you? It worked perfectly for me.

;the string to change
$str1 = "$gui = GUICreate($OETitle, $GuiWid, $GuiHt, $moepos[0], $moepos[1])"

;Change the 4th parameter
$res2 = StringRegExpReplace($str1,"(\$gui\s*=\s*GUICreate\([^,]*,[^,]*,[^,]*,)([^,]*,)(.*)","$1 800,$3")
ConsoleWrite("Result 1 >" & $res2 & @CRLF);works as I want but only in case is correct

;same change but set case insensitivity for first group
$res2 = StringRegExpReplace($str1,"(?i \$gui\s*=\s*gUICreate\([^,]*,[^,]*,[^,]*,)([^,]*,)(.*)","$1+800,$3");(?i:$gui\s*=\s*guicreate)")
ConsoleWrite("Result 2 >" & $res2 & @CRLF);doesn't work for case insensitivity in first group

Result 1 >$gui = GUICreate($OETitle, $GuiWid, $GuiHt, 800, $moepos[1])
Result 2 >$gui = GUICreate($OETitle, $GuiWid, $GuiHt, $moepos[0], $moepos[1])

Edit01: Fixed code tag.

Hrm,

Jarvis

I am expecting $res2 to be the same as $res1 with 800 replacing $moepos[0] but it doesn't as your result shows. It get the same as you do.

Something is wrong, that's for sure. Most likely the documentation.

If enclosed in brackets all works well. For the group only (I tested only too):

$res2 = StringRegExpReplace($str1,"((?i)\$gui\s*=\s*GUICreate\([^,]*,[^,]*,[^,]*,)([^,]*,)(.*)","$1 800,$3")
ConsoleWrite("Result 2 >" & $res2 & @CRLF)

For all:

$res2 = StringRegExpReplace($str1,"(?i)(\$gui\s*=\s*GUICreate\([^,]*,[^,]*,[^,]*,)([^,]*,)(.*)","$1 800,$3")
ConsoleWrite("Result 2 >" & $res2 & @CRLF)

The first one is what he wants. That is definitely a bug. Want to report it Martin since you found it?

That's a good idea to use (?i) within the group; it seems to be a way round. Thanks trancexx.

(?i) is not actually a way round, it is the way to set case-insensitive from that point on, to the right, in my opinion.

(?i: ... )

(?i)

The two patterns from the help file are correctly documented and work correctly.

(?i ... )

This pattern from the help file could be better described. But, is probably referring to this quote from the link in the help file under StringRegExp :-

"(?im-sx), which sets PCRE_CASELESS and PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also permitted."

I think it does work as trancexx suggested.

$Test = "aBcDeFGHi"
$res1 = StringRegExpReplace($Test,"(?i)(abcd).*(fg)","$1pink");try with case insesitive for all
ConsoleWrite("Result 1 >"  & $res1 & @CRLF)

$res2 = StringRegExpReplace($Test,"((?i)abcd).*(fg)","$1pink");try with case insensitive for first group only
ConsoleWrite("Result 2 >"  & $res2 & @CRLF)

gives

Result 1 >aBcDpinkHi
Result 2 >aBcDeFGHi

which is what is wanted. It also seems logical to me.

I think the easiest fix would be to change the documentation to show this way.

Martin,

Yea I tested trancexx's code, and it does do exactly as you were wishing. He just grouped the case-insensitive ALL within a group, which works, but we expected the other described option to work as described in the help file.

Thanks,

Jarvis

After looking over the documentation on PCRE.org, it would seem that Malkey is correct. We'll see how the Developers decide to fix this. They may have added that syntax themselves, or where ever they got their engine from (if not directly from PCRE), then it may have added that small extra in the syntax.

Anyways, glad you got a working solution Martin.

In my opinion this is definately not an Autoit a bug, other than possibly with the documentation.or a PCRE bug either for that matter

I've tried the following with several different regular expression engines and get the same results with all

This is not a valid regular expression pattern

"(?i\$gui\s*=\s*guicreate\([^,]*,)(\[^,]*,)(.*)"

This is a valid pattern but as well as making the first group case insensitive it also makes it non-capturing

"(?i:\$gui\s*=\s*guicreate\([^,]*,)(\[^,]*,)(.*)"

This is the correct pattern to achieve what the OP wants

"((?i:\$gui\s*=\s*guicreate\([^,]*,))(\[^,]*,)(.*)"

LOL, your third expression is yet another way of doing the same thing. I love Regular Expressions... so many ways to skin the same cat.

I agree it seems to be more of a documentation bug not a AutoIt or PCRE bug. The only way this would be different, is if AutoIt added that functionality for itself because it makes sense. If you can do a ?i: then why not simply a ?i so you can capture.

Just my humble opinion,

Jarvis

AutoIt use the official PCRE engine so if the doc which has been been from the old time when it was noy using it is incorrect please post what you suggest to change.

as you note so many way to do the same thing does not help to have a simple doc !!!

I don't see where any of you gurus even bothered trying to play with \E or (?-i).

Experiment people, it's the best way to learn SREs.

The first thing to change is to remove the part of the documentation which says that

(?i...) Case insensitive group. Behaves like a normal group....
