multiline regex matching

[skepley]

I am trying to match a regular expression over multiple lines in a macro and it doesn't seem to work. It also doesn't work in the find menu which makes me wonder if there is something subtle about the regex implementation. I thought it was based on javascript. But then the following regex:

ab([\s\S]*)c

should match the text:

ab
c

but it does not. However, if I remove the line break e.g.

ab c

it matches without issues. Is there some special syntax I need to use for matching over multiple lines? Thanks.

txs search only works per line.

Thanks for the reply. I will have to find some workaround.

@sunderme Is there any workaround? Or why TXS only support search in line?
If I want to use ^\s*\r?\n to elliminate empty line, which is a common requirement, but it doesn't work in TXS.

To work on a complete file, the best solution is to use javascript macros, see https://github.com/texstudio-org/texstudio/wiki/Scripts and https://texstudio-org.github.io/advanced.html#script-macros

In your case, e.g. https://github.com/texstudio-org/texstudio/wiki/Scripts#remove-all-empty-lines
