FunctionList Confused

@mapje71
Thanks mapje71.

That did the trick…I obviously cut and paste too few space on the copy.

Now if I can just figure out what regex, goes where…etc. :) Thanks again, and yes, I did figure out that the Java FunctionList xml isn’t a mixed parser, just a classrange parser that can find the methods in the class. At least, most of the regex is readable in that file for me to try and get a handle on it.

openSymbole=“class”

Still need to figure out if this will work, but in the meantime, I think I had an epiphany about how the regex fits into the FunctionList, and would appreciate an up or down on if the understanding is correct, bearing in mind, I’m just picking up regex, the boost flavor, and learning the NPP FunctionList functionality. :) No pressure.

So the “mainexpr” gathers all the possible text that can be gathered in a file, just to read it, not necessarily to parse it, so capturing or non-capturing shouldn’t matter (or does it?) and the following breakdowns start reading through the same code, most of it non-capturing until it gets to the desired area (Class or Function name in this case) and then captures that, so the next step in the breakdown is left only to look at the captured text from the previous breakdown…and is therefore used by the parser to identify and place that Class, Class Function(method), or separate Functions outside that body into their proper place for the FunctionList. Would that be a proper understanding of the process?

In my testing, I’ve been using all capture groups to isolate and identify syntax, and I think that’s why I didn’t get any kind of response from my FunctionList testing for class…besides not having the Classrange,Classname function working…but like I said, I’m confused and unsure about this process…but am plugging away at trying to understand what I need to do to get it to function properly. This part of the process isn’t that well documented, which is why I’m asking if this is the proper analogy while I continue to beat my head against the wall. :)

Have you read the user manual that explains basic Function List behavior?

Lycan Thrope

@michael-vincent
Yes I have, but like I said, I’m new to all these tools, so I’m trying to understand what I see there and “how” to implement it. Understanding what you’re trying to do makes it a bit easier than trial and error…that’s all. So does my description make sense of what I’m seeing? That’s what I’m asking…my understanding, versus the mainstream understanding. Like people that learn by reaading, others learn by seeing, and yet others learn by trial and error, all good, but the important thing is do they understand…and that’s what makes clarity of a process…I’m at that point, of trying to understand what I’m trying to do.

Does that make sense?

@michael-vincent
Maybe this will clarify what I mean. I have taken these variations of the syntax for the Class declaration starting line. (Watch for wrap):

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

I have come up with variations of the regex to match all of these, the last ones working the best to cover all variations. (Watch wrap):

1: ^(class)\s([a-zA-Z0-9]+)\s([a-zA-Z0-9+]+)\s([a-zA-Z0-9+]+)
2: ^(class)\s(\w*)\s(\w*)\s(\w*)
3: (?x)^[\t\x20](class)[\t\x20]+((\w+)|(\w+)[\x20]+(((\w+)(,\w+)?))?)?((\w+|[^\r\n])[\t\x20]+)(custom)? <—best
4: (class)[\t\x20](\w+)([\t\x20]?(\w(,[\t\x20]?\w*)?))?([\t\x20]of[\t\x20]\w((\w*(,[\t\x20]?\w*)?))?([\t\x20]custom)?([\t\x20]from\t\x20)?)?
5: (class)[\t\x20](\w+)([\t\x20]?(\w(,[\t\x20]?\w*)?))?(([\t(\x20]of)[\t\x20]\w((\w*(,[\t\x20]?\w*)?))?([\t\x20]custom)?([\t\x20]from\t\x20)?)?
6: (class)[\t\x20](\w+)([\t\x20]?(\w(,[\t\x20]?\w*)?))?([\t(\x20]of\t\x20)?((\w(,[\t\x20]?\w*)?))?([\t\x20]custom)?([\t\x20]from\t\x20)?
7: (?:class)[\t\x20](?‘Classname’\w+)([\t\x20]?(\w(,[\t\x20]?\w*)?))?(([\t(\x20]of)\t\x20((\w(,[\t\x20]?\w*)*?))?(\t\x20)?([\t\x20]from\t\x20)?)?

Now having done that, what’s the next step, or did I do it right, or have I included enough information to get what I need in “mainexpr”, and where do I get “nameexpr” to extrapolate from that?..How do I seperate the wheat from the chaff, so to speak? If you run this through regex101.com, it works like a charm. Trying to put it in the .xml file, hasn’t been as successful. ::shrug::

Yikes, it looks like the forum editor did some editing of my strings in the regex…argh…but I hope you get the point. I’m knowing just enough to be dangerous. :)

Unfortunately, the backticks to make the multiline brackets work, will have to be manually removed to run the regex’s…and the backticks around the whole regex did not turn it red typewriter text. :(

Lee

Lycan Thrope

@lycan-thrope Hmmmm Let me try this. Test
'red typewriter text’1: ^(class)\s([a-zA-Z0-9]+)\s([a-zA-Z0-9+]+)\s([a-zA-Z0-9+]+)

Have you read the user manual that explains basic Function List behavior?

Maybe this community post is a little more detailed than the user manual?

Cheers.

You have read the FAQ wrong.

the syntax

1. `^(class)\s([a-zA-Z0-9]+)\s([a-zA-Z0-9+]+)\s([a-zA-Z0-9+]+)`

renders as

^(class)\s([a-zA-Z0-9]+)\s([a-zA-Z0-9+]+)\s([a-zA-Z0-9+]+)

which you can then just copy/paste the red text.

Please note that what you had,

1: ‘^(class)\s([a-zA-Z0-9]+)\s([a-zA-Z0-9+]+)\s([a-zA-Z0-9+]+)’

is not the same as

1: `^(class)\s([a-zA-Z0-9]+)\s([a-zA-Z0-9+]+)\s([a-zA-Z0-9+]+)`

which renders correctly as
1: ^(class)\s([a-zA-Z0-9]+)\s([a-zA-Z0-9+]+)\s([a-zA-Z0-9+]+)

The ` key (often called “backtick” or “grave”) is the one that on a standard US keyboard is the same key as ~, but unshifted . You are typing the single-quote / apostrophe key ' (which on a US keyboard, is the unshifted version of ", the double quote). The single-quote in the forum is then being rendered as ‘smart single quotes’ ‘...’ in your post.

The Formatting Forum Posts gives you plenty of copies of the ` character, which you can copy/paste if you are unable to type the character on your keyboard.

@peterjones said in FunctionList Confused:

`

Peter, thanks for clarifying that for me. I just want to show you why I used that character, besides not realizing where the backtick key was. In this screenshot of your message to me, as well as in the documentation FAQ for posting, I highlighted the character to see if these old eyes could make out what it was, and as you see, the little pop up that “says” what it is, is mistaken. :) Thanks for fixing that for me. :) Screenshot of what I saw:

So really, thanks for clearing that up for me. :)

Lycan Thrope

@lycan-thrope
So…let’s try this again, so I can see if it work right, with just the backtick.
7: (?:class)[\t\x20]*(?'Classname'\w+)([\t\x20]*?\(\w*(,[\t\x20]?\w*)*?\))?(([\t(\x20]of)[\t\x20](?'Superclass'\w*)(\(\w*(,[\t\x20]?\w*)*?\))?([\t\x20](?'Custom'custom))?([\t\x20]from[\t\x20](:\w*:\w*\.\w*|"\w*\.\w*"))?)?

Woohoo…the preview shows it working, but as per the FAQ let’s see if it does it without all the backticking in side the regex on the multiline brackets. :)

Lee

Lycan Thrope

@lycan-thrope One more time…with the whole thing. :)

These are the regexs I built leading up to the final ones (4,5,6,7) that work with the complete line in some or fashion. Still need to watch the word wrap.

1: ^(class)\s([a-zA-Z0-9]+)\s([a-zA-Z0-9+]+)\s([a-zA-Z0-9+]+)
2: ^(class)\s(\w*)\s(\w*)\s(\w*)
3: (?x)^[\t\x20]*(class)[\t\x20]+((\w+)|(\w+)[\x20]+(\((\w+)(,\w+)?\))?)?((\w+|[^\r\n]*)[\t\x20]+)*(custom)?
4: (class)[\t\x20]*(\w+)([\t\x20]*?\(\w*(,[\t\x20]?\w*)*?\))?([\t\x20]of[\t\x20]\w*(\(\w*(,[\t\x20]?\w*)*?\))?([\t\x20]custom)?([\t\x20]from[\t\x20](:\w*:\w*\.\w*|"\w*\.\w*"))?)?
5: (class)[\t\x20]*(\w+)([\t\x20]*?\(\w*(,[\t\x20]?\w*)*?\))?(([\t(\x20]of)[\t\x20]\w*(\(\w*(,[\t\x20]?\w*)*?\))?([\t\x20]custom)?([\t\x20]from[\t\x20](:\w*:\w*\.\w*|"\w*\.\w*"))?)?
6: (class)[\t\x20]*(\w+)([\t\x20]*?\(\w*(,[\t\x20]?\w*)*?\))?([\t(\x20]of[\t\x20](\w*))?(\(\w*(,[\t\x20]?\w*)*?\))?([\t\x20]custom)?([\t\x20]from[\t\x20]((:\w*:\w*\.\w*)|("\w*\.\w*")))?

The word “QUOTE” shows up like that if you select any text:

It is not telling you what character that is. It is the Forum asking you if you would like to use the selected text as the QUOTE portion in your reply.

If you have multiple lines of example text, use the LITERAL TEXT BOXES , not the RED TYPEWRITER TEXT.

But this is getting off the point, and you have shown your regexes. So unless you have more about FunctionList, I think we’ve spent enough on forum formatting.

@michael-vincent
Thanks Michael, that’s where some of the understanding is coming from, with the ability to read english via the Java.xml versus the cpp.xml, but since I’m not completely familar with java’s syntax and variations, it’s still clear as mud, but getting clearer. :-)

Lycan Thrope

@peterjones
I do appreciate your help, in this regard. I’ve been around awhile, but have to admit, posting in here, is a little different that what I’m used to, even after reading the FAQ…thanks for that clarification, though. Hate to look dumber than I am. :)

Okay, so no after beating the keyboard and my head all day, I figured it was time to present what I have tried and still doesn’t work…but to be fair, all I’m trying to do is get FunctionList to see my class first. Baby steps.

This is my functionlist file:

I hope the fact that I don’t have a function search in it yet won’t be the problem, as all I want to do is verify I have the regex, the .xml file correct, and the settings and files in the right place. If it’s my regex and .xml, I won’t feel bad, as it’s new…what can I say, but I think I did it right. ::shrug::

Sorry if the .xml file is a bit long, but I copied it and emptied the C++ code figuring I was going to do this quick and left all the mixed parser stuff in it. ;-( Anyone see, off hand what I’m doing wrong or what’s wrong? I get no acknowledgement of even the file existence in the FunctionList head…that can’t be a good sign. :-(
