FunctionList Confused

@lycan-thrope
Well, kind of at a loss to explain this. I’ve gone over the installations again, made sure the Appdata directories had the right files, even went into Admin mode to make sure it wasn’t rejected. The folowing screenshot shows the overrideMap.xml at the end where the UDL association is stored.
Mind you, this was while I only had the UDL in the dialog box, not stored in the UDL folder in AppData area.When I thought, hmm…maybe the file needs to be in the UDL Appdata folder I took an exported version I’ve made, renamed it appropriately “dBASEPlus.xml” and now I have this:
I wasn’t able to get it to work without the duplicate there or not. I’m going to delete the UDL file contents to see if that does the trick, either way, all the file extension needed were listed in that UDL and the pasted and copied version of Peter’s code still wasn’t working, so it must be me. :-(
File extensions in UDL file:
I guess I’ll need to retrace my steps.

Smacking self vigorously about the face and head. :-(I’m glad I was re-reading out posts, and noticed that I had NOT exactly put the right name in the associations I had spelled it “dBasePlus” in the non-working file and after changing it to the proper “dBASEPlus”, it worked on reboot…so thank you very much Peter for saving me from myself. Maybe now I can get to some productive work of finishing this UDL for use for the community and of course, if it’s of use to this NPP community, it’s of course usable…just need to check how to add it to the UDL’s. Of course, I need to make sure the rest of the keywords are put in, don’t collide with each other and other delimiters etc…and make sure I can fully flesh out as much as I can without having to actually write a lexer for the language, because…let’s face, I don’t think I’m qualified for that extensive bit of work. :-)

Next hurdle, I need to addess and ask about. Does the parser only handle one class and multiple functions per file? Or does it require for a class to be listed that it has a function in it?I tried using my original code with some of Peter’s and found it messing up on the class not showing up, and the functions acting a little erratic. I’ve put it back to the way he wrote it now, with one or two changes that don’t seem to affect the end result, but I’m checking the different kinds of files we use, and one in particular, our .cc file which usually are Custom Component files include more than one class.
In the one I was testing of my own creation, of the multiple classes I have in it, only one of them has a function, and it was the only one that showed up in FunctionList panel, which is what prompted this question coming up. If I just need to work further to get it to function listing classes, that is one thing, but if it’s not built to that, I wanted to check, as I don’t seem to have any multiple class code files available right now for any of the languages available in NPP…I will but just don’t have them right now…and it’s getting late time to stop beating the keyboard. :) Thanks in advance.
Here’s two screenshots of the one class, multiple functions and one of the multiple classes but one function in the FunctionList panel.

It can handle multiple classes, but for a class to be listed, it must have at least 1 function in it. It can also handle “main” functions - that is, functions not in a class.
Cheers.

Hello, @lycan-thrope @peterjones, @michael-vincent and All,
Sorry to be late ! From your functionList file, provided in this specific post, I tried to re-build and simplify your regexes which allow to detect all the syntaxes of
DBasePlusclasses, as well as the class names !-
I added, at beginning, the
(?-i)in-line modifier for a search sensitive to the case -
I mainly used the
\hsyntax, instead of[\t\x20], as it’s equivalent to[\t\x20\x85] -
I replaced any
\w*syntax by\w+, as we don’t search for empty words ! Don’t we ? -
I suppressed some useless groups
-
I changed some complex multi-lines groups
(•••••)in the non_capturing equivalent groups(?:•••••) -
I kept the first optional parameter(s) part as group
1, which is re-used, with the same syntax, in the optional ‘of’ part
Leading to the following class part of the

@guy038 ,
I tried replacing my simple class detection with yours, and it doesn’t show the classes – even when I keep my function definitions. When I put your expression into FIND, it’s back to matching only a single line, not the whole class – so that means, it can never find a function inside that class, and it thus won’t display anything in the function list (which is the second problem I pointed out here: “
mainExprneeds to match all of the text in the class…”)If we use the function blocks from my “my simple mixed parser now works”, and incorporate your regex (unaltered), then I get
… which is not finding it as a class, and is instead finding it as a top-level function (which isn’t what it really is).
This does confirm that defining
closeSymboleisn’t enough to get it to extend the class toendclasseven when not in themainExpr.Thus, if I add
(?s:.*?^\h*endclass) # must match all the way to 'endclass'after your $ line in the
mainExpr, which will then find
@Lycan-Thrope , That last line I added defines a non-capturing group where
.-matches-newline, and finds as few characters as possible between the end of the class-starting-line, and the first instance of the wordendclassat the beginning of a line (with potential whitespace before) – thus making themainExprmatch the whole class, not just the first line of the class.<?xml version="1.0" encoding="UTF-8" ?> <!-- ==========================================================================\ | | To learn how to make your own language parser, please check the following | link: | https://npp-user-manual.org/docs/function-list/ | \=========================================================================== --> <NotepadPlus> <functionList> <!-- ========================================================= [ dBASEPlus ] --> <parser displayName="dBASEPlus" id ="dbaseplus" commentExpr="(?s:/\*.*?\*/)|(?m-s://.*?$)" > <classRange mainExpr="(?x-i) # Free-spacing mode and inline comments + search sensitive to case ^\h* # Optional leading whitespace chars class # 'class' keyword \h? # Optional whitepace char \w+ # Class name # Following the class name there is the option of parameters, and if so the first entry inside the parens is required, whether there is other # parameters or not, once the parens go up, the first is required. ie: class FrameCtrl(frameObj) ( # Beginning of the optional parameter(s) part ( Group 1 ) \h? \( # Opening parenthesis \w+ # First and required parameter ( , \h? \w+)* # Following optional/additional parameters \) # Closing parenthesis )? # End of the optional parameter(s) part # For the rest of the class declaration, after the class name, all other options are part of one big optional set, that follows 'of' # and can be populated by one of several options.

@guy038
Thanks guy038, for this lesson in regex construction. I was curious if I was being overly verbose in my regex for that line, but it does work correctly the way I wrote it in regex101.com, so I presumed it would work here. So far, although it works in the sandbox over there, and it does work in the find in NPP, I was still, as Peter points out next, not able to capture all the way to endclass, so this version still did what mine was doing. :-)…but I did pick up, because I understand my syntax, where I need to use capturing and non-capturing groups, as I was a bit lost as what meant what and where. So thanks. Here’s a screenshot, that shows the same thing I discovered last night…err early this morning before I called it quits that shows what I messed up, and Peter’s new version corrects. Mine, which you duplicate less verbosely, shows that the first class in the list gets listed with the function that actually belongs to a class further down in the code.
So thanks for the education, though. :)

@peterjones ,
Thanks, that works much better, and as I pointed out above, it fixes a problem I discovered late last night, this morning, that shows the wrong class with the function attached to it…which I’m going to guess is the problem you fixed with including that endclass in the expression. I was trying that also, but my verbose and maybe confusing capturing grouups was probably preventing it from working to that point. ::shrug::Here’s a screenshot of my multiclass file showing the proper class with the function that your parser code finds.
Thank you for getting this correct, if I’m not able to show classes without functions as Michael Vincent states(shout out to Michael), at least it now shows the right class with the found function.
This lack of class showing without functions, however, kind of hurts the purpose of my goal which was to use the FunctionList panel as a navigational tool, much like in the dBASEPlus editor that shows the classes and objects included in each class to be able to jump to those classes and objects to edit them. Some of the .cc files can be quite extensive since they can hold all the UI modifications a developer may want to put in it, and many of the code files can get quite large and need a some help navigating. I guess we could circumvent the problem by putting a null function in every class to compensate for the lack of ability to get the FunctionList to display the classes. But thank you for helping getting this to work properly.

If a class will always have at least one of “with” and “function”, then change the
functioninside theclassRangeto:<function mainExpr="(?x-s) \h* (?: function \h+ \w+ | with \h+ \(.*?\) ) \h* " > <functionName> <funcNameExpr expr="(?x-s) # multiline/comments \h* # allow leading spaces (?: function # must have word 'function' as first word \h+ # must have at least one horizontal space after function \K # don't keep 'function' in the name of the function in the panel \w+ # the name of the function is the first whole word after 'function' | with # must have word 'with' as first word \h+ # must have at least one horizontal space after function \K # don't keep 'with' in the name of the function in the panel \( # start paren .*? # 'this' or equivalent \) # end paren ) " /> </functionName> </function>It will then give the “argument” to
withas a function name as well…
It might not be exactly what you want, but it comes close. -
@peterjones
You’re a genius. :-)Every class does indeed, as far as I know, have to have a
thisandwith endwithconstruct that sets the properties of the object it will create, unless it is only copying and giving a different name to a default superclass.I was going to ask and point out that I thought the C++ mixed parser that MAPJe71 shows in the FAQ, would work because it shows a function being declared inside the class construct, but actually being defined outside.
dBASE has a similar thing where it is assigned as a property
onOpen = class::objectsname_onOpen
and then is later either actually defined in the class definition, or externally defined (if that’s possible). I know we define helper functions outside of the class constructor that are either defined in the same file, or an external file that will be named as needed or prior to the start of the form or function it’s being called in. Like I said, it’s kind of loosely typed and ambiguous, but it works :)I tried my earlier suggestion of putting a null function in each class and took a screenshot of it.
Simple search and replace on endclass and adding the fake function made it work, but I kind of like yours better, maybe using the
thisorwithwords will work better. Thanks for this.Lee

@peterjones
Incidentally, Peter.While trying to copy this over, I hadn’t read that I should put this in the classrange/function body, and had put it in the funtion body outside. No biggie right. I took the copy from the upper post, took this and copied it into the right section, then set about to remove my fake function from the .cc file using the search terms and switching them between search and replace boxes. After going through the list, which I thought for sure, I had bypassed the only class with a real function I saved and ran the program, only to find that I had replaced the real function.
Argh…panic set in. Oh wait…I have a .bak file of the original saved one. I recopied it and then tested the functionlist again and viola. See how disparate threads lead to one point? :-) Saved from myself, again. :-)
Anyway, thanks for this. I think you have made it very possible for this package to be a nice Christmas present for the dBASEPlus community that has been longing for an external editor with the basic features of the IDE editor with some of the more advanced tools available in Notepad++ of which many were users, but didn’t have highlighting which NPP now makes it possible for use to combine the use. Now our folks, as one user put it, be able to edit the file externally, and run it right away without having to close the editor just to compile the program. Of course, thanks to the default .bak choice, it will not function like our environment to save us from it and ourselves. :-)

Hi, @lycan-thrope, @peterjones and All,
As you can see, there are different ways to get an element, whatever it is, listed, in the
Function Listpanel !!I’ll explain what my process was, for writing my previous post and how I tested my regex solution !
First, from the initial list of the
9class syntaxes, provided by @lycan-thrope, below :class TruckNotebookForm of TBASE from :Truck:Truckbase.cfm class PlainObjectListForm of FORM class FrameCtrl(frameObj) of dBCWndCtrl custom class dBCWndCtrl class FrameAppCtrl of FrameCtrl custom class ToolButtonFx(oParent) of Toolbutton(oParent) custom class MenuFx(oParent,cName) class dContainersForm of DFORM from "dForm.cfm" class LGCENTRYFIELD(parentObj, name) of ENTRYFIELD(parentObj, name) customI decided to search, first, for a regex solution, only, without any reference to the
Function Listmechanism ! In addition, I considered only the line of theclassdefinition ! After modifications, I ended up with the followingMainExprregex :(?x-i) # Free-spacing mode and inline comments + search ensitive to case ^\h* # Optional leading whitespace chars class # 'class' keyword \h? # Optional whitepace char \w+ # Class name ( # Beginning of the optional parameter(s) part \h? \( # Opening parenthesis \w+ # First and required parameter ( , \h? \w+)* # Following optional/additional parameters \) # Closing parenthesis )? # End of the optional parameter(s) part (?: # Beginning of the main optional part \h of \h # Optional 'of' keyword, surrounded by 1 horizontal whitespace char \w+ # Superclass name (?1)? # Optional parameter(s) part ( \h custom )? # Optional 'custom' keyword (?: # Beginning of the optional part \h from \h # Optional 'from' keyword, surrounded by 1 horizontal whitespace char ( : \w+ : \w+ \. \w+ # First pointing file case | # OR \x22 \w+ \. \w+ \x22 # Second pointing file case ) )? # End of the optional part )? # End of the main optional part and end of the class declaration
If you select all the text between
(?x-i)and the last comment..... and end of the class declaration( so a selection of1,607chars, which is under the maximum of2,046chars ) and open the Find dialog (Ctrl + F), you’ll verify that it correctly matches the9syntaxes, provided by @lycan-thrope !Of course I, tested my regex solution and was upset to notice that it would also match wrong pieces of code :-((
For instance, after taking the last syntax and adding a
#char in some places, it would wrongly match some part of the two lines, below :class LGCENTRYFIELD(parentObj, name) of ENTRYFIELD(parentObj, #name) custom class LGCENTRYFIELD(parentObj#, name) of ENTRYFIELD(parentObj, name) customAs you can see, as soon as a part contains a non-allowed char (
#), my regex skips it and just matches the minimum valid form :-( I finally solved this problem by adding, at the end of my regex, the$symbol which forces the regex engine to get valid syntaxes on a complete line !So, the right multi-lines regex, for the
mainExprattribute, is rather :(?x-i) # Free-spacing mode and inline comments + search ensitive to case ^\h* # Optional leading whitespace chars class # 'class' keyword \h? # Optional whitepace char \w+ # Class name ( # Beginning of the optional parameter(s) part \h? \( # Opening parenthesis \w+ # First and required parameter ( , \h? \w+)* # Following optional/additional parameters \) # Closing parenthesis )? # End of the optional parameter(s) part (?: # Beginning of the main optional part \h of \h # Optional 'of' keyword, surrounded by 1 horizontal whitespace char \w+ # Superclass name (?1)? # Optional parameter(s) part ( \h custom )? # Optional 'custom' keyword (?: # Beginning of the optional part \h from \h # Optional 'from' keyword, surrounded by 1 horizontal whitespace char ( : \w+ : \w+ \. \w+ # First pointing file case | # OR \x22 \w+ \. \w+ \x22 # Second pointing file case ) )? # End of the optional part )? # End of the main optional part $ # End of current line and end of the class declaration
And you’ll notice, this time, that the last
2syntaxes, below, are not matched, as expected :class TruckNotebookForm of TBASE from :Truck:Truckbase.cfm class PlainObjectListForm of FORM class FrameCtrl(frameObj) of dBCWndCtrl custom class dBCWndCtrl class FrameAppCtrl of FrameCtrl custom class ToolButtonFx(oParent) of Toolbutton(oParent) custom class MenuFx(oParent,cName) class dContainersForm of DFORM from "dForm.cfm" class LGCENTRYFIELD(parentObj, name) of ENTRYFIELD(parentObj, name) custom class LGCENTRYFIELD(parentObj, name) of ENTRYFIELD(parentObj, #name) custom class LGCENTRYFIELD(parentObj#, name) of ENTRYFIELD(parentObj, name) customHowever, this second version still considers the current
classdefinition line as the only domain to study, without any further stuff and/or anyendclassstatement !
In a second time, I tried to test this final regex version with the
Function Listfeature. So, in theoverrideMap.xmlfile, I added the line :<association id= "dBasePlus.xml" langID= "0"/> <!-- Normal Text ID -->Then, I used the general template, provided by @lycan-thrope, to build a correct
dBasePlus.xmlfile. But, NO chance, I was unable to get the list of classes, in theFunction Listpanel :-(( I suppose that relation between classes and functions, in amixorclass parser, must be of importance ! But after numerous tries, I gave up, as I’m rather not acquainted with modern structured languages :-(But, as I’m rather stubborn, I decided to simplify the problem by using a simple
function parser. Of course, in this case, the “elements”, detected by theFile Listmechanism, are seen as functions but, actually, may represent any element that we need to be listed. For instance, presently, thedBasePlusclasses !From this old page, caught by the
wayBack Machinesite :https://web.archive.org/web/20190826024431/https://notepad-plus-plus.org/features/function-list.html
I used this minimal form of a

@guy038 , your efforts are appreciated, like I said, if only to show I could have been less verbose.
Originally, I was trying to decipher the C++ FunctionList structure, but was getting dizzy trying to figure it out since it’s not my native language, so regex aside, some of the structures it was trying to capture was dizzying. Hence I tried shifting to the Java FunctionList to study, and it helped show I didn’t need the organized chaos that C++ was. :-)
It still, however, seemed to me to be trying to parse a single line to of possible options for the lines, so I began my journey trying to just regex the options of that one line. My hope was to be able to just get that recognized and just show the class name. I still don’t completely understand the workings of FunctionList, but even though Peter and you both seemed to help solve the problem, I’m happy, but still playing just to advance my knowledge of this and see if I can’t enhance or improve things.
If nothing else, this little experiment has kind of turned me on to regex, which I’ve never needed or used until now to make this. I’ve done my own little parsers, but in C or dBASE, simple little things, but dealing with the regex that had to be put inside the xml and figure everything out was …let’s just say kind of overwhelming, but educational. So thanks for that.
I find trying to regex new lines and such in the Find search of NPP doen’t work for me trying to get down to the “endclass” part and was frustrating as hell trying to make it work, using what seemed like the proper way, using the ‘class’ and ‘endclass’ keywords in the open and close symbole seemed like a simple answer…but it wasn’t…so, here we are :-) I’ve shown screenshots to the community and they’re salivating for it. Anyway, this is a work of love so thanks again. I do understand the stubborn part. I’ve been banging the head and neglecting my house chores trying to crack this, which is why I finally relented and reached out…and grateful that I did.
Happy Holidays while I try and tie this package up for delivery. :-)

Hello @lycan-thrope, @peterjones and All,
Well, today is an other day ! So, let’s go on studying some more structures !
Let’s suppose, as previously mentioned, that you need the general
classsyntax, below, that you’ll paste in a new tab :class Test_1 bla blah with (this) bla bla blah endwith blah bla bla endclass classTest_2 bla blah with (this) bla bla blah endwith blah bla bla endclassSo, after a simple
classdefinition line, you would need :-
Further on, a line with the
withkeyword and its parameter(xxxxx), after possiblewhitespacechars -
Further on, a line with the
endwithkeyword, after possiblewhitespacechars -
At last, a line with the
endclasskeyword, after possiblewhitespacechars
Then, each entire
class •••••••••• endclasssection, which meets all the rules, could be matched with the multi-lines regex, below :(?sx-i) # We MUUST add the '(?s)' in-line modifier as we search for a MULTI-LINE range of chars ^ \h* # Optional leading whitespace chars, beginning a line class # Mandatory 'class' keyword \h? # Optional whitepace char \w+ # Class name $ # End of current line ((?!endclass).)*? # The SMALLEST range of characters, even NULL, NOT CONTAINING the 'endclass' keyword, till ... ^ \h* # Optional leading whitespace chars, beginning a line with # Mandatory 'with' keyword \h # Mandatory whitepace char \( \w+ \) # Mandatory parameter name, between parentheses $ # End of current line ((?!endclass).)*? # The SMALLEST range of characters, even NULL, NOT CONTAINING the 'endclass' keyword, till ... ^ \h* # Optional leading whitespace chars, beginning a line endwith # Mandatory 'endwith' keyword $ # End of current line ((?!endclass).)*? # The SMALLEST range of characters, even NULL, NOT CONTAINING the 'endclass' keyword, till ... ^ \h* # Optional leading whitespace chars, beginning a line endclass # Mandatory 'endclass' keyword $ # End of current line
Note that, in order to get the smallest range of chars between two lines of importance, as
with,endwithorendclass, we have to use the regex syntax((?!endclass).)*?and not the simple regex.*?. Why ? Just because it must not match a greater rangeclass ••••• endclass ••••••••••••••• class ••••• endclass, in the case where an innerclasssection does not satisfy the regex rules ! Thus, the keywordendclassmust not be present at any position of the range !Now,
-
Select from
(?xs-i)to the last# End of current line -
Open the Find dialog (
Ctrl + F) -
Test it, against the above text : it should select any block of lines, between the
classandendclasslines !
Finally, if we insert this additional regex part, in the
dBasePlus.xmlfile, we obtain :<?xml version="1.0" encoding="UTF-8" ?> <!-- ==========================================================================\ To learn how to make your own language parser, please check the following link: https://npp-user-manual.org/docs/function-list/ \=========================================================================== --> <NotepadPlus> <functionList> <!-- ========================================================= [ dBASEPlus ] --> <parser id ="dBasePlus" commentExpr="(/\*.*?\*/)|(?-s://.*)" > <function mainExpr="(?x-i) # Free-spacing mode and inline comments + search ensitive to case ^\h* # Optional leading whitespace chars class # 'class' keyword \h? # Optional whitepace char \w+ # Class name # Following the class name there is the option of parameters, and if so the first entry inside the parens is required, whether there is other # parameters or not, once the parens go up, the first is required. ie: class FrameCtrl(frameObj) ( # Beginning of the optional parameter(s) part \h? \( # Opening parenthesis \w+ # First and required parameter ( , \h? \w+)* # Following optional/additional parameters \) # Closing parenthesis )? # End of the optional parameter(s) part # For the rest of the class declaration, after the class name, all other options are part of one big optional set, that follows 'of' # and can be populated by one of several options.

There are two options for pointing to the file. The first is an Alias path in the IDE that can be accessed by the compiler # in the environment, or second, it is in the current directory and only the name is needed...or it has a path that can be listed here, # but this is bad practice, and an Alias is recommended if the file is in a place other than the current directory. If it is, the name can be # used in quotes as a string that gets passed to the compiler. Both follow the word 'From'. The Alias directory is a name that is enclosed # in two colons, one immediately before the Alias name and one immediately after, no spaces.

Function Listparser, we do not have to add the(?s)modifier. This is enabled by default, meaning that the dot regex symbol.matches absolutely any character of theBMPUnicode plane !Best Regards,

@guy038 ,
That made sense, and I can use that to play with, because it did what I was trying to, although, so far, Peter’s and your contribution to it works great.
I was curious, however if I play with it further, and maybe Peter can also verify or deny, if I can get NPP to make it’s display look more like the dBASEPlus editor’s if I work more at the regex in the parser. Not so much the graphics, as just the way it breaks down the class, objects and functions etc. If not, believe me, what you guys did is fine…I’m just curious if it’s possible or not. Screenshots of both on Identical file.
dBASEPlus:
Notepad++:
Yeah or nay? :-)

Maybe with the regex I can change the names to drop the ‘this.’ and burrow down to the name of the object itself I guess is what I would mean. I’m going to play with it anyway, I just don’t want to break it. :-)Lee

As a note, Peter, thanks for that code. I had forgotten an older but not obsolete alternative tofunctionin the dBASE language, namelyprocedurethat is essentially the same as a function’s syntax. It used to be used pre OOP days, and dBASE used to differentiate them, but that disappeared when it went OOP, but it was never removed and maintained to be compatible because the OOP version is still able to run older procedural code and it’s still recognized.I was able to figure out how to add that in the OR that you had setup, and the first time I ran it, it showed that it was highlighting a different aspect of dBASE, where you can
set procedure toa file that has external code and it highlighted the wordtoand included it in the FunctionList panel, so I was able after learning from guy038 the different way to write regex to (!to) and successfully run it without error. Learning a lot from you guys. :-)Just feeling good about that…not as good as you guys yet ;), but working on it.

Hey Folks,I found a bit of a problem. I searched the forums to see if there was a previous issue with FunctionList words being found inside comments, and I think even Peter made a comment in it that it still had a bug that required to spaces or some such to keep it from listing in the FunctionList.
So, I double checked and the following screenshots show my problem with apparently any time a keyword (function, procedure, with/endwith) shows up in any comment. I know I didn’t regex the (&& comment characters) but it doesn’t seem to make any difference as it shows in this screenshot:
I also checked to make sure the comments were being considered by rechecking the FunctionList regex for the comments symbols (// and /* */) and they were as the screenshot shows, these are standard comment symbols that are supposed to be ignored:
I also tried to change the regex in the search to not include comment symbols from the start of the line search, by using a similar regex like I used to exclude “to”.
(! // | && | *)All this did was stop even the legitimate finding of functions from working altogether.
So I guess the question is, has this bug been fixed, or is there some way I can exclude these Functions from being found inside comments and listed?
Thanks in advance for any help and wishing all a Happy New Year during these holidays,
Lee

Hi, @lycan-thrope,
Be patient
4/6hours. I’ll have a look into your problem. I think I’ve got a work-aroud to solve the detection of the wordFunctionin comments !Best Regards,
