Help converting Notepad++ format to Pythonscript

Claudia Frank

sorry, didn’t understand that you want a python script solution with regular expression replacement.

regex = r'(\(.*?\))|(\w+)\s'  
editor.rereplace(regex, lambda m: '{}{}'.format(*m.groups()))

Cheers

I am most-curious about why the OP (@Andrew-Clark) could get his regex replacement working in interactive N++ and not with Pythonscript, but perhaps that is a question that isn’t going to get answered…my guess would be not using raw string notation (the leading r in r'regex') in the PS…

Claudia Frank

or maybe it was about how to get the match groups returned as replacement … ??

Hello @andrew-clark, @scott-sumner, @claudia-frank and All,

I was away this weekend, to hike in the Cevennes mountains and my feet still remember theses rides ! As you can imagine, just sitting, comfortably, in front of your laptop and discussing Notepad++ matters is a real treat ;-))

So, Andrew, as for me, I would use, with native N++, the regex S/R, below :

SEARCH (?-s)(\(.+?\))|\x20

REPLACE ?1\1

Notes :

As usual , the (?-s) modifier means that any regex dot character ( . ) will match a single standard char., only.
Then, this regex would match :
- First, any shortest range of chars, between parentheses, stores it as group1 and rewrites this group as it is. ( Note that the ( and ) characters have to be escaped, with a \ symbol, to be considered as literals ! )
- Secondly, any space character, just ignored in replacement.

Cheers,

Hi Guy, nice shortening but one question - it seems that ?1 is, for the posted example data, not needed in the replacement - what is the idea behind it?

Thank you and cheers
Claudia

Just in case someone wants to add this into a python script it would now look like this

regex = r'(?-s)(\(.+?\))|\x20'  
editor.rereplace(regex, lambda m: '{}'.format(m.groups()[0]))

I don’t know…the Pythonscript docs for editor.rereplace() seem to have an adequate example of this…but considering it now maybe it could be made better?

there is always room to improve something - so, yeah - go for it. :-D

Hi, @andrew-clark, @scott-sumner, @claudia-frank and All

Sorry, for my late answer as I was elaborating a regex, for the tricky case, below :

https://notepad-plus-plus.org/community/topic/16053/how-to-ascend-numbers/3

Ah, how silly am I ! Of course, when the regex finds a space character ( the second alternative ), the group1 is not defined. Thus, in replacement, it simply rewrites…nothing, as group1 represents a zero-length string ;-))

Clever deduction, Claudia. So a possible regex is :

SEARCH (?s)(\(.+?\))|\x20

REPLACE \1

Note : I also changed the (?-s) modifier into (?s), which allows possible multi-lines ranges of text, between parentheses !

Best Regards,

Ah :-(( I should have tested my idea of changing (?-s) into (?s), before posting. Actually, in case of multi-lines range of characters, between parentheses, the suitable regex S/R is , rather :

SEARCH (\([^()]+?\))|\x20

REPLACE \1

Hope it’s the right one, this time :-D
