Need help with getting started using C++ Plugin Template

Yeah, there’s the JSON which has the information for 3 of the 4 file types (because Themes are a separate repo and not attached to the UDL). So it should be doable to automatically download all the appropriate files for a UDL (though I might make that be an option, because someone might want to just grab the updated UDL, without overwriting their previously-customized FunctionList, for example).

Good point, as that would be an option, as I am probably going to need that for when I update the dBASE UDL definitions for all the versions that I’m working on now, to make more of the language color configurable for users via the UDL defintion dialog by including builtin functions/commands that they can custom color as well as, if I organize it well, leave a Keywords box open so they can put their own function definitions in it separate from the standard ones.
Just an FYI, the light and dark modes are actual languages in the different versions, not themes.

@PeterJones said in Need help with getting started using C++ Plugin Template:

I don’t see a reason for that, for me. NPPM_GETNPPDIRECTORY tells you where notepad++.exe is for the current instance, which is the only parent directory for autoCompletion. And NPPM_GETPLUGINSCONFIGDIR, which tells you where Notepad++ Plugins\Config is, which is relative to %AppData% for standard, relative to notepad++.exe for local, and should* be relative to CloudDirectory or -settingsDir if one of those options is chosen.

Your installer needs the more complicated code, because you are running outside of Notepad++ environment, but the plugin should have access to all the information it needs to put the files in the right location.

Which, if I was somewhat able to code in C++, using the NPP plugin would have made my life simpler then, at least from the installer perspective. :-)

would you prefer:

After hitting DOWNLOAD for the first file, the dialog closes itself, so you have to re-run the Plugin command to get the next file

After hitting DOWNLOAD for the first file, when it’s done, it pops up a MessageBox to inform you it’s done, and you can go immediately get another file from the same dialog

After hitting DOWNLOAD for the first file, when it’s done, it changes a status bar on that dialog to indicate that it’s complete

Other ideas (the less complicated, the better)

I would do the reverse of 2: raise a dialog box while the content is downloading, then close it when the download is finished. I looked just briefly at your project; since you’re using an asynchronous interface (wininet) you should be able to put a cancel button on the downloading dialog. (Progress would be more work; I’d guess these files are small enough that it wouldn’t be necessary?)

You could still put up a status message showing the last thing that happened (downloaded, or download cancelled or failed) and the item name.

Your button layout is non-standard. It’s allowed, but might confuse users. The rightmost button is usually Cancel or Close. (No real difference, but Cancel usually goes with a single-use OK, whereas Close usually goes with a dialog that has other options and stays open after one or more of them.)

The Restart button leaves me wondering if it means “Download what I have selected and then restart” or “Restart without downloading anything (more).”

If it means just Restart, I would put it to the far left and disable it until at least one file has been downloaded successfully, and put the Download button just to the left of the Close button, disabled until there is a valid selection.

If it means download and restart… then it’s more like an OK button. In that case, I suppose I would put Download to the far left, but really consider the multiple selection option.

A possibility would be to just have Download/Close (if you only want one selection at a time) or OK/Cancel (for multiple selections). Then, upon Close (if at least one file has been downloaded) or OK, raise another dialog asking whether the user wants to restart.

I believe it’s to restart Notepad++, to allow for the UDL/Themes to be able to be active, is what it means, this of course would mean that it’s going to close the dialog of the Plugin as well.

alpha testing

For those interested in alpha testing, the copy at https://github.com/pryrt/NppPlugin-CollectionInterface should now have all features implemented, though it definitely needs error handling improvements (right now, it will throw uncaught exceptions)

Well, I probably did something wrong, but this is what I got after building your .dll in VS2022, and then creating the directory in the Programs\Notepad++\Plugins\CollectionInterface directory and copying the CollectionInterface.dll into it and trying to start NPP.

Like I said, it might be me, all I did was clone your github directory to my github desktop directories and ran VS 2022, went to that directory as a project in it and then hit build. Not sure if it’s a program error, mine or not compatible with 8.7.7, which my current standard install is at. I’ll try it in one of my portable RC’s if that matters.

@Lycan-Thrope ,

Per MS Learn > GetTempPath2W(), that function is in Kernel32.dll, so ~~I cannot see why it wouldn’t be found for you.~~ [update: see next reply]

~~Are you sure you were building the 64bit DLL for the 64bit Notepad++?~~

Because I didn’t do anything special other than linking the Plugins\CollectionInterface directory to the VS build output (as described above), along with setting the run command to use my normal Notepad++ (also mentioned above). It works for me when I run it either from the VS Run button, or when I just manually run Notepad++ normally.

Mine is v8.7.5, but I don’t see how anything I’ve coded would be NPP-version dependent

PeterJones

@Lycan-Thrope ,

The same MS Learn page mentioned at the bottom:

Requirement	Value
Minimum supported client	Windows 11 Build 22000
Minimum supported server	Windows Server 2022 Build 20348
Header	fileapi.h (include Windows.h)
Library	Kernel32.lib
DLL	Kernel32.dll

I hadn’t previously noticed that. I just saw that GetTempPathW told me to use GetTempPath2W instead.

Try changing from GetTempPath2() to GetTempPath() (which has been around since WinXP, If that fixes it, I will update the repo tomorrow.

@PeterJones ,
Looking for it now, but it appears to only show up in system files using the Code Search, and I don’t want to change VS2022 files…will change it when I find it in your code.

Lycan Thrope

@PeterJones ,
Okay, that fixed it.
ROFLMAO, I couldn’t find out how to use VS 2022 search to just find the file it was in, so I had to use Notepad++ Search in file feature to find it in the right .cpp file. God you got to love Notepad++ for it’s simplicity and funtionality.

I may not be familar with VS 2022…but searching for code shouldn’t start at the libraries and never mention the opened code folder where it is. Sheesh.

Now to check out your handy work…remember, we all aren’t using Win 11. :-)

Lycan Thrope

@PeterJones ,
It worked beautifully. I was able to download my dBASE UDL files, and install them in the right directories. The only problem, is that the Autocomplete and Functionlist aren’t functional because of the lack of linkage via the overrideMap.xml file, that didn’t include the association. That’s the only remaining issue, of automating it completely. :-)

Lycan Thrope

@PeterJones ,
One other thing, is that the names have to be consistent, and mine were all over the place. The file internal names (for the UDL definition) and the names in the autoCompletion and functionList and the overrideMap.xml file. That’s the weak spot at this point, is being able to keep the names consistent between the internal file name and the rest. I only did the Light version and had to modify all of them, because the long names in the repository, don’t match the names needed in the rest of the linkages needed for the files. At least, mine. :-)

Other than that…where was this thing when I needed it. I could have focused more on the things I’m trying to do now with the UDL, but had to write the darn installer because of the namings required. :-)
I’m going to have to look at your code and stuff now, so maybe I can learn from it as it’s apparently something I’m interested in.

@Coises,

might confuse users. The rightmost button is usually Cancel or Close

I knew that, but since RESTART N++ is “even more close than CLOSE” – it’s a more drastic “exit this dialog”, since it also exits and restarts the application, so I thought that it might be more logical to be further right than the DONE. I’ll probably reorder and rename to DOWNLOAD, RESTART N++, and CLOSE (instead of DONE)

if it means “Download what I have selected and then restart” or “Restart without downloading anything (more).”

Odd, I wasn’t expecting any confusion, especially since the instructions in the dialog explain why you would need to RESTART. I’ll definitely have the README explain things in more detail, but maybe I’ll add a HELP interface of some sort.

If it means just Restart, I would put it to the far left and disable it

I like the idea of disabling it… But putting it on the far left doesn’t make sense to me, because the primary action of the dialog is to DOWNLOAD, and I tend to think of the buttons as being layed out left-to-right in the order they would be used: since you would DOWNLOAD first, it would be leftmost, and then you would either RESTART or CLOSE, depending on your preferences, so those would go to the right. What’s your reasoning for putting the RESTART on the left?

really consider the multiple selection option

We’ll see. Doing the automatic or at least optional “also download AC and/or FL when you download the UDL” makes sense to me… but I’m not as certain about downloading multiple UDLs at the same time.

since you’re using an asynchronous interface (wininet) you should be able to put a cancel button on the downloading dialog. (Progress would be more work; I’d guess these files are small enough that it wouldn’t be necessary?)

With the downloading happening self-contained in a method on the object, rather than being inside the dialog-handler, I’m not sure of an easy way to signal the class/method to stop the download. Progress, in my mind, would be easier, because if I just passed the control for the progress bar as an argument to the download method, it could send the right signals at appropriate times. But we’ll see what I can figure out.

yes, that does get confusing. And I’ve just realized that I might have to work on the autoCompletion naming, because I think I’m basing it off the JSON’s “id-name” field (ie, the UDL’s filename) rather than basing it off the JSON’s “display-name” field (which is what Notepad++ calls the UDL, and what I understand the autoCompletion feature needs for file naming on UDLs; I’ll have to double-check.[*]

The file internal names (for the UDL definition) and the names in the autoCompletion and functionList and the overrideMap.xml file.

The functionList requires the overrideMap update. If named correctly, autoCompletion should “just work” (though “if named correctly” is a big caveat; see my previous paragraph in this reply ;-))

Other than that…where was this thing when I needed it.

Just an idea at the back of my mind, at that point. Sorry I’m not a time traveler. ;-)

[*] update: yes, AC files must match the “display-name” (ie, the <UserLang name="XYZPDQ" ... name); I need to update the CONTRIBUTING.md to make that clear, and eventually update the automatic checks run on the repo so that any AC filename must match its associated UDL actual-name. Yay, another thing for my growing TODO list on this project. ;-)

What’s your reasoning for putting the RESTART on the left?

(All these things are just thoughts from someone who is merely looking at your writing and images and hasn’t used the program or tried to implement any part of its function. If my tone sounds a little know-it-all, please accept my apology in advance; it gets unreadable to qualify everything with “I think maybe, if you like the idea”; but I’m really not trying to say everything should be the way I say, even if succinctness sometimes makes it sound that way.)

Usually dialogs which you call up via a command either show requested information, let you specify changes and then either OK or Cancel them, or let you make changes “live” and then Close them.

In all those cases, when the dialog closes, you are (in some sense) back where you started when you opened it. The buttons at the bottom in the center or at the right of a dialog usually represent actions within that flow.

Closing and restarting the host program is a more drastic action than one normally associates with a dialog. Buttons don’t usually go on the left; when you see one there, you know (maybe subconsciously) that something is different about that button.

However, the more I think about it, the more I would recommend just the two buttons — Download and Close — and then raise an message box after the user closes your dialog if anything was downloaded. (Users are more used to a message box — if it appears when the action they took didn’t represent the intent to raise a dialog — indicating something unusual happened, will happen or might happen depending on their choice.) In that separate step, tell the user the changes won’t take effect until Notepad++ is restarted and ask whether to do that now. (Yes or No, No should be the default.)

(This isn’t something people are going to do often, so clarity is more important than keystroke efficiency.)

I will keep the Category as a dropdown (since there are only 4), but yeah, it makes sense to make the file list a List Box.

If there are only four categories, and they are always the same, and the names are short, consider radio buttons. (Or tabs: not a true tabbed dialog, since the content would be always the same single list box populated with different data; just the visual appearance. I haven’t used one in a while, but if memory serves the Tab Control itself is really just like a group box with a selector on top; what you put in the box is your business. If I did that, I would also put the Download button in the tab box, under the list box, with the close button below and outside the tab box.)
