I'm using netbeans and I want to wrap $this->escape(stuff) around specific stuff in more files, using the replace feature, but there's plenty of conditions, like:
match:
$this->$variable, $variable
$this->$array['something'], $this->$array[0], $array['something'], $array[0]
do not match:
$this->partial, $this->escape, $this->form
What I have so far that works ok
replace this
echo\s+(\$this->[->a-zA-Z_']+[^\s;(])
with this
echo \$this->escape\($1\)
It doesn't work with arrays and doesn't exclude anything, also doesn't match $variable
Could anyone help out, improve the expression so that it would reduce the torture of going through so many strings by hand? Any help is appreciated.
edit: just adding the exclusions to my working example would be enough.
It's not entirely clear what parts you're trying to match. If I understood you correctly then this should work:
(?:\$this->)?\$[^,\s-]*(?=[,\s])
If you meant to match something else, please let me know.

I have wrote this regex to help me extract some links from some text files:
https?:\/\/(?:.(?!https?:\/\/))+$
Because I am using golang/regexp lib, I'm not able to use it, due to my negation (?!..
What I would like to do with it, is to select all the text from the last occurance of http/https till the end.
sometextsometexhttp://websites.com/path/subpath/#query1sometexthttp://websites.com/path/subpath/#query2
=> Output: http://websites.com/path/subpath/#query2
Can anyone help me with a solution, I've spent several hours trying different ways of reproducing the same result with no success.
Try this regex:
https?:[^:]*$
Regex live here.
The lookaheads exist for a reason.
However, if you insist on a supposedly equivalent alternative, a general strategy you can use is:
(?!xyz)
is somewhat equivalent to:
$|[^x]|x(?:[^y]|$)|xy(?:[^z]|$)
With that said, hopefully I didn't make any mistakes:
https?:\/\/(?:$|(?:[^h]|$)|(?:h(?:[^t]|$))|(?:ht(?:[^t]|$))|(?:htt(?:[^p]|$))|(?:http(?:[^s:]|$))|(?:https?(?:[^:]|$))|(?:https?:(?:[^\/]|$))|(?:https?:\/(?:[^\/]|$)))*$
could you please give me some advice, I'm replacing the <chemform> code from my wiki which is not used any more... The strings are usually simple like these:
<chemform>CH3COO-</chemform>
<chemform>Ba2+</chemform>
<chemform>H2CO3</chemform>
I need them to be replaced by these:
CH<sub>3</sub>COO<sup>-</sup>
Ba<sub>2</sub><sup>+</sup>
H<sub>2</sub>CO<sub>3</sub>
So far I came up with this regexp for the RegExr tool:
match: <chemform\b[^>]*>(\D*?)([0-9]*)(\D*?)(\D*?)([0-9]*)(\D*?)([-+]*?)</chemform>
replace: $1<sub>$2</sub>$3$4<sub>$5</sub>$6<sup>$7</sup>
I know the code is horrible, but so far it's been working for me except for the fact it's getting me empty strings like <sub></sub>:
<sub></sub>CH<sub>3</sub>COO<sup>-</sup>
<sub></sub>Ba<sub>2</sub><sup>+</sup>
H<sub>2</sub>CO<sub>3</sub><sup></sup>
How can I get rid of these without doing second replace search? Thanks a lot!
You could use Notepad++, which is able to proceed to conditional replacements (you can have details in that previous post from Wiktor Stribiżew).
Use the following patterns:
match: ([A-Za-z]+(?=[-+\d]))(?<sub>\d+)?(?<sup>[-+])?(?=[-+\w]*</chemform>)
replace: $1(?{sub}<sub>$+{sub}</sub>)(?{sup}<sup>$+{sup}</sup>)
Given your input sample, I get:
<chemform>CH<sub>3</sub>COO<sup>-</sup></chemform>
<chemform>Ba<sub>2</sub><sup>+</sup></chemform>
<chemform>H<sub>2</sub>CO<sub>3</sub></chemform>
Can someone please advise how to do this search and replace in textmate. I think I need a REGEX (but i know very little about REGEXes!)
i want to change all these bullet images to GIFs...
bullet-1.png
becomes
bullet-1.gif
and I want where the number is to be a wildcard
The regular expression:
bullet-(\d+).png
The replacement:
bullet-$1.gif
I tried to make regex syntax for that but I failed.
I have 2 variables
PlayerInfo[playerid][pLevel]
and
Character[playerid]
and I want to catch only the second variable,I mean only the world what don't contain PlayerInfo, but cointains [playerid]
"(\S+)\[playerid\]" cath both words and (\S+[^PlayerInfo])\[playerid\] jump on some variables- they contais p,l,a,y ...
I need to replace in notepad++,all variables like Text[playerid] to ExClass [playerid][Text]
Couple Pluasible solutions.

Notepad has a plugin called python script. Running regex from there
gives full regex functionality, the python version anyway, and a lot
of powerful potential beyond that. And I use the online python regex tester to help out.
RegRexReplace plugin helps create regex plugins in Notepad++, so when you do hit a limitation, you find out a lot quicker.
Or of course default to your alternate editor (I'm assuming you have
one?) or this online regex tool is absolutely amazing. You
can perform the action on the text online as well.
(I'd try to build a regex for you, but I'm a bit lost as to what you're looking for. Unless the Ivo Abeloos got it. If you're still coming up short, maybe a code example along with values displayed?)
Good luck!
It seems that Notepad++ support negative lookbehind since v6.
In notepad++ you could try to replace (.+)\[(.+)\] with ExClass\[\2\]\[\1\]
Try to use negative lookbehind.
(?<!PlayerInfo)\[playerid\]
EDIT: unfortunately notepad++ does not support negative lookbehind.
I tried to make a workaround based on the following naive idea:
(.[^o]|[^f]o)[playerid]
But this expression does not work either. Notepad++ seems to fail in alternative operator. Thus the answer is: it is impossible to do exactly what you want. Try to solve the problem in other way or use alternative tool.
In a LaTeX report I am making I have to write a regex. There is only one in the whole report, so I don't really want to use packages and so on.
This is the regex I am talking about:
^\"((\w|\s)+)\"$
I came up with this for LaTeX:
\grave{ }\backslash\"'((\backslash w\| \backslash s)+)\backslash \"' \backslash \$
This gives me like 10 errors, and I can't really see what is wrong. Okay, it looks pretty bad but all the commands should work.
Thanks in advance,
Harm
Use \verb/^\"((\w|\s)+)\"$/
Perhaps the problem is that some of those commands (\backslash, \grave) want to be in math mode, but \" doesn't. Have you tried using \verb to include the regexp verbatim? I'm not sure if it'll look like you want (it'll be typeset in a tt font), but you could do this with something like:
...
In my project I'm using a regexp \verb#^\"((\w|\s)+)\"# to do a thing.
