FunctionList classrange question

[oirfeodent]

@MAPJe71
The parser did not show me the “functions” section and the related functions for me.
Only showed the following.

+--- filename.bc
     +--- choice.test.123
     |    +--- before.choice
     |    \--- after.choice
     |
     +--- field.field.123
         \--- on.input

Not sure which part I am missing.
Reattaching the full <parser> tag what I picked from the above post.

am I missing something?

[MAPJe71]

@oirfeodent Make sure there’s an empty line at the end of the .bc file.

[oirfeodent]

@MAPJe71
Still no luck, after adding the last empty line.

[MAPJe71]

@oirfeodent

[oirfeodent]

ok, let me check if I have missed something.
Probably do a fresh install of NPP.

[oirfeodent]

@MAPJe71
Removing the “commentExpr” attribute from the <parser> worked. Thx.

I have started building the regex to add the other sections and have an additional question.
For instance, in the <classrange> known section names, if I want to check “before.<anyname>:” main section but should not check “before.choice:|before.checks:” sub section… can it be acheived?

I tried with

|	(?:before\.[^checks|choice|delete|display|field|form|group|input|layout|print|read|rewrite|write|zoom|display\.object|new\.object|program])(?:(?:\.)*\w+)+

This doesn’t seem to work. I also tried to create negative look ahead but failed.
Let me know if you have some suggestions.

Regards,

[MAPJe71]

@oirfeodent
Do you mean something like

|	before(?:\s*\.\s*(?!checks|choice|delete|display|field|form|group|input|layout|print|read|rewrite|write|zoom|display\.object|new\.object|program)\w+)+

[oirfeodent]

@MAPJe71
The above is close to expected output.
In the sample file below, the “before.program:” main section gets listed as the sub section of “choice.test.123:” main section.
Sample file:

choice.test.123:
before.choice:
	funct1(10)
on.choice:
	funct1(10)

before.program:
	set.synchronized.dialog("fxinh0123s000")
	
functions:
function func1(long var1)
{
    | Do Something 1.
}

The expected output is

+--- filename.bc
     +--- choice.test.123:
     |    +--- before.choice
     |    \--- on.choice
     |
     \--- functions:
          \--- func1

But the “before.program:” also gets listed under “choice.test.123:” for the below <classrange> tag.

				<classRange

Adding/removing the ‘:’ to the negative look ahead provides the same results.
Any possibilities?

@oirfeodent Could you provide a complete list of:

1. valid section names i.e. invalid sub-sections names;
2. valid sub-section names i.e. invalid section names.

All the sub-sections are definite.
The main sections inside the <> can be anything based on the description; but has to exist.
So, “after.<charsDigitsPeriods>.<digitsOnly>:” should end with a “.<digit>:” to be a valid MainSection.
None of the main sections are mandatory (even functions: main section can be skipped).
None of the sub sections are mandatory (But atleast one sub-section would exist (Though not mandatory))

Apart from this, there are two kinds of script.

1. Regular Script… which will have atleast one of the above sections and optionally the “functions:” sections along with functions.
2. dll script… which doesn’t have any of the sections, but only functions.

Sample dll script:

|This is a dll script, which does not have any sections.
function extern long func1(long var1)
{
	|do something
}

function void funct2(long var2)
{
	|do something
}

Sample regular script:

choice.test.123:
before.choice:
    funct1(10)
on.choice:
    funct1(10)

before.program:
    func1(10)
    
functions:
function func1(long var1)
{
    | Do Something 1.
}

                            \s*\(

I have changed the \h+ to \s+ so that functions spanning multi-lines are shown properly. Do you see any issues with that?

Another point is about embedded comments… for below sample

function extern 	|Test
long test()
{

}

if I remove the “|Test” it is shown in the Function List panel… but, with the comment in place it doesn’t show this function.
So, is there a possibility to check for the presence of comments and ignore the same?

@MAPJe71 Thx so far for your time and effort.

[MAPJe71]

@oirfeodent comments “embedded” in the function/method header are not supported (see also parse steps in earlier post).

[oirfeodent]

@MAPJe71
I thought with the <parser> “commentExpr” -attribute it is not possible to have embedded comments.
I was playing around with RegexBuddy with the simplest version of the function parser and used the following regex to have the function name highlighted with embedded comments.

function\s+(\|\w*)*\s+\K\w+(?:\.\w+)*\s*\(

However it failed with the regular function without embedded comment.

function |TEST
test()
{
     |highlighted function name
}

function test()
{
      | No highlight. (I guess regex is not correct to handle both)
}

So, I thought there could be a better way for doing this which I am not aware.
Hence the question, as the “commentExpr” attribute is not defined.

If no other way, then also fine. Thx.

[MAPJe71]

@MAPJe71
Thx. PR has been created based on above https://github.com/notepad-plus-plus/notepad-plus-plus/pull/3842
Only change is that domain keyword also checks for . (period) apart from \w class and also allow embedded comments. Can you have a look and approve the changes if you are ok.

If not, let me know.
Regards,

[MAPJe71]

@oirfeodent see PR #3842 for my review.
