The find macro is a powerful Wikitext macro to find a substring delimited by two delimiters (beging: the delimiter shows the start of snippet, and end: the delimiter shows the end of snippet). The find macro finds part of text separated by delimiters. This is a powerful macro to extract text snippe…

I saw the other thread " The User Defined Extract Filter Operator ", started to reply, then realized it might be more appropriate if I elaborate more on my solution here instead. Firstly, for searching substrings marked by two delimiter strings, regexp seems suitable for the task. For other tools, t…

This is a good idea @Mohammad . I was looking at the current macro and wonder if it could first be annotated more by yourself or written as pseudo code? This would allow others to more easily consider the design. I may look at doing this for myself I am keen to make use of this in a range of appl…

I gave it a try using regexp: \procedure linefeed() \n <$let t=""" This is a ##test1%% for a #search1%% and #replace1%% in ##text1. This%% is a ##test2% for a #sea#rch2% and%% #replace2% in #text2%. This is a ##test3% for a #sea##rch3%% and #replace3% in #text3%. """ start="##" en…

Thank you @jacng . Your solution in form a procedure is given below. To be able to work with the special characters used in regular expressions, I change the code a little bit, note to the escaperegexp. \procedure linefeed() \n \procedure findp(text, start, end) <$let searchString=`.*?${[<start>esc…

Why the linefeed has been removed? Is it possible to keep them and instead use multiline flag?

That was my first thought as well when I started working on this. ‘m’ flag means multilines search which is what’s needed here. I checked my wikitext codes for how I used it previously, but my old codes were removing linefeeds to do a multiline search instead of using the ‘m’ flag ?!? Can’t recall…

Hi @jacng Thank you for the hint! I will experiment to keep the linefeeds. In some cases, like extracting all macros in a bunch of tiddlers, you need to keep the text structure (including linefeeds).
