@Min-Liu I would like some time to review the php lexer code as the powershell and python lexer shows better performance with the same text pasted under similar test conditions. Perhaps there is some bad code logic preventing good progression of the styling in the php lexer. This needs some proving in some way to recognize the lexer as bugged and will test in SciTE with similar settings to reproduce the bug.

LuaScript as suggested can help you for now though if the php lexer needs a fix then it should get priority with posting an issue and where it should be posted. This may take some time as the lexer code is complex.

@PeterJones I just tested in SciTE SC1 version 5.5.8 Scintilla:5.5.8 Lexilla:5.4.6 with idle.styling=3 in SciTEGlobal.properties. It pastes the 50,000 lines without freezing into a .php file. Can you possibly confirm this test as this implies the php lexer is OK in SciTE, yet is not OK in Notepad++. If confirmed, then the lexer seems OK and goes back to being a Notepad++ issue. The idle styling was not the only setting in Notepad++ that was changed. The versions of Scintilla/Lexilla match with Notepad++ 8.9.

@PeterJones Thanks so much for the quick reply. Installing the release candidate fixed the issue for me. Much appreciated!

@PeterJones said in Pascal multi line string highlight:

[pascal]
; Everything between pairs of triple-ticks is colored cyan
0xCCCC00 = (?s)‘’‘.*?’‘’
;excluded_styles = 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,20,21,22,23
(make sure you use the ; or # to coment out the excluded_styles, otherwise it won’t color properly; you can, of course, pick any 0xBBGGRR values you want to choose your own color, as described in the comments of the INI file.)

Thanks for the workaround, I used here and have some problems, when i have more than one multi-line string on a single document sometime the string is colored sometime everything else are colored.
To make it works I changed to this rule:

[pascal] 0x9393CC = (?s)(?<=[=,\(]){1}\s*('{3,}).*?\1

Now to considere the text the trhee or more apostrophe needs to be preceded by come caracteres like =, ( or [.

I tryed to search by the same amonth of ticks, it is working just well enough, but not exactly fine.

@PeterJones said in The problem with notepad.runMenuCommand:

Simple and light is often the opposite of universal.

This is often the case, but not always.

@PeterJones said in The problem with notepad.runMenuCommand:

If you solution is “universal enough” for you, fine;

Of course, when there is no ideal option, you have to choose the one that is most suitable for the situation.

@Alan-Kilborn said in The problem with notepad.runMenuCommand:

Good luck achieving all of those all of the time.
Or do you have a “pick any 2” or “pick any 3” type rule? ;-)

Thanks. It happens to everyone at some point ;)
But it must be universal and fast, even if it means making the code complex.
