Function List not working in v7.2

Mike Behar

Function List displays nothing in Notepad++ V7.2 (32 bit)
Using functionList.xml from version 6.9.2 fixes the issue

MAPJe71

What language(s)?

Gary W

It doesn’t work for me, either. JavaScript, for one, doesn’t do anything. I tried replacing functionList.xml from 6.9.2, but I still get nothing.

Claudia Frank

@Gary-W

check your functionlist.xml file, it should work.

Cheers
Claudia

Gary W

I have a functionList.xml file, it doesn’t work. The function list is empty for JavaScript files. Earlier versions worked.

Gary W

This is a clean install of Notepad++ 7.2.2 32-bit on Windows 10.

Florent Pagès

Just try to modify you functionList.xml file this way.

add :

		<association langID="19" id="js_function"/>

and add the parser

		<parser id="js_function" displayName="Javascript" commentExpr="(?s:/\*.*?\*/)|(?m-s://.*?$)">
		
			<function

				mainExpr="((^|\s+|[;\}\.])([A-Za-z_]\w*\.)*[A-Za-z_]\w*\s*[=:]|^|[\s;\}]+)\s*function(\s+[A-Za-z_]?\w*\([^\)\(]*\)|\([^\)\(]*\))[\n\s]*\{"
			>
				<functionName>


					<nameExpr expr="[A-Za-z_]\w*\s*[=:]|[A-Za-z_]?\w*\s*\(" />
					<nameExpr expr="[A-Za-z_]?\w*" />
				</functionName>



				<className>
					<nameExpr expr="([A-Za-z_]\w*\.)*[A-Za-z_]\w*\." />
					<nameExpr expr="([A-Za-z_]\w*\.)*[A-Za-z_]\w*" />
				</className>
			</function>
			
		</parser>

It’s works don’t ask me why !

MAPJe71

Notepad++ should assign the “L_JAVASCRIPT” language ID (= 58) to JavaScript files. It appears to assign the “old” language ID “L_JS” (= 19).

@donho is this a regression or am I missing something?

Claudia Frank

@MAPJe71

my function.xml has even a note

Don't use L_JS (19) use L_JAVASCRIPT (58) instead!

not to use 19 and as I’m 100% sure that I never touched javascript configuration,
because I don’t like java at all (I don’t want to start flame war - java has its validity)
I have to assume that this is the standard configuration.

Cheers

Gary W

19 or 58, nothing works. Where can I find a corrected functionList.xml?

Gary W

There are two different files named functionList.xml. One is in Program Files (x86)\Notepad++. The other is in User\XXX\AppData\Roaming\Notepad++.

The latter one is much bigger and more comprehensive, and by default, uses 58 for the association ID. This file also has the apparently incorrect statement “Don’t use L_JS (19) use L_JAVASCRIPT (58) instead!”

When I change the association to 19, the function list works!

Claudia Frank

@Gary-W

depending on your configuration whether to use %APPDATA% configuration or not the respective
functionlist gets loaded. I’m still confused that your saying that after changing the id it is working for you.
Could it be that you use an embedded js version as in html?

Cheers
Claudia

Gary W

No, I am using straight-up JS files, Claudia.

Claudia Frank

@Gary-W

ok - I can confirm. After complete deinstall and a wiping of all files and folders in
my installation directory and under %APPDATA% (which I thought I never used)
I reinstalled npp7.2.2. 32bit. Now I have the same behavior. The reason why it was working before is that I run into the doLocalConf bug.
I can’t say which version started ignoring the file but it seems 7.2.2 is doing it.
So @MAPJe71 was completely correct and I have to apologize.

Cheers

– Ver 7.4.1 32bits. for me the problem is still here. so I patched again my functionList.xml

Hi @all,

I also found a bug in the regular expression of the JavaScript parser for matching the pattern of a function header. If between the function name and the left parenthesis of the parameter list have been inserted one or more blanks the parser failed to find the function header.

Npp version

v7.4.1, 32 bit

File

C:\Program Files (x86)\Notepad++\functionList.xml
copied to
C:\Users<UserName>\AppData\Roaming\Notepad++\functionList.xml

Corrected JavaScript parser

<parser
	displayName="JavaScript"
	id         ="javascript_function"
	commentExpr="(?s:/\*.*?\*/)|(?m-s://.*?$)"
>
	<function
		mainExpr="((^|\s+|[;\}\.])([A-Za-z_]\w*\.)*[A-Za-z_]\w*\s*[=:]|^|[\s;\}]+)\s*function(\s+[A-Za-z_]?\w*\s*\([^\)\(]*\)|\([^\)\(]*\))[\n\s]*\{"
	>
		<functionName>
			<nameExpr expr="[A-Za-z_]\w*\s*[=:]|[A-Za-z_]?\w*\s*\(" />
			<nameExpr expr="[A-Za-z_]?\w*" />
		</functionName>
		<className>
			<nameExpr expr="([A-Za-z_]\w*\.)*[A-Za-z_]\w*\." />
			<nameExpr expr="([A-Za-z_]\w*\.)*[A-Za-z_]\w*" />
		</className>
	</function>
</parser>

The bug was located in the value of mainExpr.

I improved the parser for Inno Setup scripts too. Now it is also able to find procedures as well as functions/procedures with no or an empty parameter list. Furthermore forward declarations are no longer matched.

doesn’t work anymore for 7.4.2, why is this even an issue? this is the most basic ui test possible, very disappointing. But looking at the “new” xml structure, no wonder people have problems navigating to this custom xml interpretation.
Switching ID to 19, even though a random comment says not to, fixed this for me…
