FunctionList: v8.8.7 Perl parser is apparently inefficient
-
Based on older conversations here, I had been using an advanced version of the Perl parser for the Notepad++ FunctionList, which handles Classes (including, in Perl nomenclature, “Packages”) and Functions, compared to the simple FunctionList definition which had been shipped by default with Notepad++.
When Issue #17043 was submitted, I was prompted to submit my advanced Perl parser to be distributed, and it was released with v8.8.7.
However, soon after the release, Issue #17152 was created, claiming that even for simple Perl code, it can take multiple seconds when they switch tabs into Perl code – even for the unitTest file. I obviously hadn’t seen that over my 5 years of actively using my advanced Perl FL, but I don’t doubt that there might be inefficiencies in the regex used…
The FunctionList definition shipped with v8.8.7/8.8.8 is here.
I know that @guy038 enjoys trying to make regex more efficient, and that @MAPJe71 is much better at FL definitions than I am.
So if anyone wants to take a look at provide some efficiency advice on this FL, that would be great.
The expectations are that it would need to have the same unitTest results in the automated process, which looks like the following FL in the GUI:
I am not great at determining regex efficiency, so I don’t know what might be able to be done to the regex to help the multiple users in the new issue, without giving up and reverting to the less-functional parser that was distributed in v8.8.6-and-earlier
