I recommend waiting on that update. Search++ is not “production ready” yet. People shouldn’t be using it at present unless they want to be beta testers. Once I reach a 1.0 release I’ll make a serious effort to avoid changing things that people would expect to stay the same, but right now, anything could be changed at any time.

Numeric expressions in Search++ do not have quite all the features of numeric expressions in Columns++; in particular, the history options (using the values captured or computed in a previous match) aren’t supported in Search++, and the exprtk return statement isn’t supported.

However, I think all the features directly cited in the Math FAQ are included. The reg(1) syntax still works, but in Search++ you can use $1 as well. However, a quirk is that since Search++ doesn’t have the persistent Decimal separator is comma option of Columns++, it’s necessary to use regc(1) or $$1 for European-style numbers with periods and/or commas.

Finally, Columns++ can only work on the active document. Search++ has a Find in Files option, but Replace in Files has not yet been implemented. So if your guess was correct and @neculai-i.-fantanaru wants a regular expression because it must be applied to many files at once, @thomas-knoefel’s MultiReplace is the best choice among presently-existing options.

Oh, and MultiReplace has recently added an option to use exprtk formulas as an alternative to its Lua syntax.

For this purpose, you should study the Columns++ documentation of @coises, below :

https://coises.github.io/ColumnsPlusPlus/help.htm#formulas

or with the MultiReplace plugin of @thomas-knoefel, from these two links below :

https://github.com/daddel80/notepadpp-multireplace/blob/main/FORMULA-SUPPORT.md#lua-reference

https://github.com/daddel80/notepadpp-multireplace/blob/main/FORMULA-SUPPORT.md#exprtk-reference

As you can see, it should be possible with some special regexes to achieve your goal !

I need a regex, not column editor, not python.

If you have multiple files, it is understandable to exclude column editor, as that’s not practical. But you are choosing to exclude PythonScript: there is a difference. You have access to the plugin, and you know how to use it. So you do not need a regex, you want a regex, which are two different things.

Notepad++'s built-in regex doesn’t do auto-increment, and your previous topic with the edge cases just pointed that out to you (you ended up doing a weird duplicate and edge-case to get a pseudo-‘count’). For this task, you would need to use a plugin – either PythonScript (which you are artificially rejecting), or one of the fancier search plugins that have enabled custom “numbering” syntax – like MultiReplace or Columns++ (or presumably Search++ – I assume @Coises included all the math extras when he ported the searching from Columns++ to Search++)

The Math FAQ already explains how to do counting-like actions in PythonScript and in MultiReplace and in Columns++ (and I assume the Search++ syntax would be the same). There is no reason for us to re-iterate what’s already in the FAQ.

add number 1-16, before each line:

1-bebe-55
2-bebe-55
3-bebe-55

Notepad++'s existing “Column Editor” can do this already.
I believe the default keycombo is Alt+c (or you can find it on the Edit menu).
