PowerShell parenthesis matching
-
This was started in the Notepad++ v7.9.2 Released thread, but since the problem occurs in other versions, I have spawned a new discussion to address @magoo104’s problem.
@magoo104 said in Notepad++ v7.9.2 Released:
The following valid PowerShell statement doesn’t correctly match the parentheses. It can also mess up other valid bracket matching, but I haven’t figured out the right pattern yet.
“$($s.replace(”‘“,”’'“))”
$s can be any valid string, with or without imbedded single quotes.
The same thing happens for me on v7.9.1 (ie, previous version):
cursor is on the first(, and it doesn’t match the end, and the Search > Goto Matching Brace isn’t even available:
Whereas on the second line, it works just fine:
My guess is that the problem is with the underlying PowerShell lexer, which is technically part of the Scintilla project. To prove whether it’s a problem with the lexer or not, one needs to determine if the behavior is the same in both Notepad++ and SciTE (the Scintilla-testbed editor). If it works in the most recent SciTE , one would need to check an older SciTE v4.2.0 (which matches the version of Scintilla that Notepad++ currently uses). If it works in SciTE v4.2.0, then it’s something specific to Notepad++ and you’ll need to create an issue with Notepad++; if it doesn’t work in SciTE v4.2.0, then the bug is in Scintilla , and it needs to be fixed and released there before it can be incorporated into Notepad++.

BTW: Here is the ? > Debug Info from the version where I confirmed the same issue…

I had a copy of SciTE 4.2.0.
After editing the SciTEUser.properties (by running SciTE, then Options > Open User Options File, pasting the following, and saving…

@PeterJones said in PowerShell parenthesis matching:
The SciTE brace-matching (^E = Ctrl+E = Edit > Match Brace) works on the second line, but not on the first line.
However, more examples show: if I use real quotes rather than smart quotes:
$($s.replace(”’","’’")) ( ( ) ) $($s.replace("'","'"))The third line, which has true ASCII
"and', the brace matching works fine in SciTE 4.2.0.In Notepad++, if I leave that first line there, but add the third, it still thinks it is inside a string, which confuses things. But if I remove the first line and just have
( ( ) ) $($s.replace("'","'"))… then Notepad++ brace-matching with
Ctrl+Bworks for me.@magoo104 , could you paste in some actual PowerShell syntax that shows the problem – once you paste it in the forum, highlight the text and click the
</>button in the forum entry toolbar,
so that your PowerShell will be properly in a black box, and the Forum won’t try to “fix” your" "to“ ”or similar smart-quotes.And I did confirm: in v7.9.2, with the most recent text shown, it properly highlights matching braces, as shown in this screenshot
… andCtrl+Bworks correctly as well.So it was only with mismatched quotes and “smart quotes” that the problem occurs for me. With balanced ASCII quotes, it works just fine.
