TiddlerTweakPlugin: does the replace regexp support grouping?

[G.J.Robert]

Hi Eric and all,

I was trying to use TiddlerTweakerPlugin to replace

===<linebreak>(\+\+\+\[SomeText\].+?===)

as the regexp syntax

\1<linebreak>===

that is, I want to swap the first instance of "===" and "\+\+\+\[SomeText\].+?===" which is enclosed inside the parentheses, and represented as "\1" in the replace target string.

However, TiddlerTweakerPlugin does not seem to recognize the grouping syntax of regexp to use the shortcut "\1" to represent the whole string to be kept, and in the result of replacement, "\1" appears literally. But I hoped that I can get

+++[SomeText]SliderContent===<linebreak>===

Is there any way around to get my desired result? Thanks!

You were VERY close! Instead of "\1" , "\2", etc., javascript regexp
uses "$1", "$2", etc. as replacement markers

Thus:

===<linebreak>(\+\+\+\[SomeText\].+?===)

replace with:
$1<linebreak>===

enjoy,

Hi Eric,

Thank you so much and thank God I raised my inquiry here, because I was going to give up and prepare to use complicated export/import procedures to modify an offline TiddlyWiki HTML file and then import the tiddlers back to TSpace... And your explanation saved my day. Thanks!
