Split text based on character, but keep 'splitting character'

[GH-KN]

Hi,

Question:
in GH we have the split text component, which splits text on specific text characters given.

However, in the output, the actual splitting character is ‘deleted’.
My question is if somebody knows a way or a workaround to do this.

This topic is also discussed below, with a python solution:

How to .split() and keep the delimiter(s)

However I havent been able to get a working component just yet.

I have this monstrosity to offer, that works for several separators in the same text (it’s sort of a Shatter List !)

Hi!

thanks for your quick reply
Unforunately is has also to work when the splitting character is present in multiple original items, see e.g. below.

Any suggestions?

Hi,

Also thanks for your quick reply.
unfortunately same as HS_kim, it has to work for multiple items…

any suggestions?

Hi Thanks, again!

Almost there!
It is also possible that the items are present multiple times in 1 item. Any suggestions?

thanks!

Is there somebody who know, how to add this python script in GRasshopper?
I think this is exactly what I would need

Thanks again

Forgot to save…

I modified it so that all splitting characters are applied to each ine of text - your original post let presume that there was one character associated with each string.

Hello,

Does something like this work for you?

import re
re.split(r"(?=[,.:;])|(?<=[.,;:]/g)",text)

Hi!

Sorry for my late reply, I think this is possibly the solution I am looking for.
Unfortunately I am not an Python expert.

Would it be possible to write it in an GH - Python component, with 2 input variabels:
x = input text which has to be ‘split’
y = all ‘splitting’ characters at which the text has to be split?

so just like the component below, with the difference that the 'splitting characters should still be present?

Many thanks!

If you have a problem and you decide to solve it with regex then you have two problems

[Dancergraham (Graham Knapp)]

How is this ?

import re

splitters = "".join(y)
pattern = r"(?=[{" + splitters + r"}])|(?<=[" + splitters + r"]/g)"
a = []
for text in x:
    a.append(re.split(pattern,text))

Haha thx, again
I copied it, with the following result:

Any idea how to tweak?

thanks again!

Ahh yes it looks like you need something like this for nested lists… Ghpythonlib tree helpers - #4 by diff-arch

@GH-KN

y = all ‘splitting’ characters at which the text has to be split?

I couldn’t get this to work in a GhPython Script component using regular expression with lookahead (?=…) or lookbehind (?<=…) assertions (these work fine in a C# component).

I was able to get the results @GH-KN wanted with a GhPython Script component, but it took some extra code.
