Autocompletion across all opened files

Michael Vincent

N++ has autocomplete but it seems to be based on the content of the current file and the contents of the autoCompletion\LANG_TYPE.xml file for the given language of the current file. Writing in C++, I can think of times that autocompletion from all open files would be good - like a .cpp and .h file where I’m defining the function prototypes in the .h file and I’d like the names to autocomplete from the opened .cpp file.

I haven’t looked at the N++ code base, but I’m assuming this is done with the Scintilla Autocompletion calls? I wonder if there is a way to augment the dynamic list via plugin? Has anyone thought of this too? Has anyone tried it?

Cheers.

Afaik, you cannot modify the list npp uses on the fly but create your own list.
I use this technique together with jedi for python.
For C++ I ASSUME nppgtags might do what you want.

@Ekopalypse said in Autocompletion across all opened files:

Can you describe how you have Jedi integrated with N++ for autocompletion? I’m not familiar with Jedi so just did a quick search. Found npp_pyjedi, do you use that? Or is it custom with PythonScript?

I already use TagLEET (modified) and TagsView (modified), but neither help autocomplete while typing, they just lookup tags already typed in the document.

I see nppgtags has an autocomplete feature, but found the interface to TagLEET better to work with.

Cheers.

@Michael-Vincent

do you use that?

No, the one I linked :-)

Or is it custom with PythonScript?

Yes, Jedi is a bunch of python modules which will be accessed
by a python script plugin but for other languages it is the same I guess.
There is a need to have an “external” process running which constantly parses
your code and offers you the auto completion functionality.
What I did is this

def on_charadded(self, args):
    if self.is_python:
        c = args['ch']

        if c in ['.', ' ', '(']:
            pos = editor.getCurrentPos()
            if (editor.getCurLine().find('#') > -1 or
                editor.getStyleAt(pos) in [3, 4, 6, 7]):
                return

            source = editor.getText() + c
            line = editor.lineFromPosition(pos) + 1
            column = editor.getColumn(pos)
            script = jedi.Script(source, line, column, '')

            if c == '(':
                self.show_calltip(script, pos)
            else:
                if c == '.' and editor.callTipActive():
                    editor.callTipCancel()
                self.autocomplete(script, pos)

Whenever a charadded notification is sent I check if this is a python document and if it is
act according to the added char. If it is a ( I call a calltip and in case it is a . I ask for completion.
I could have done it for every single char but I don’t like to get a offer to autocomplete always.
I mostly been interested in methods and attributes from classes etc…

@Michael-Vincent I came looking for the same info. I started to use Atom because it picks up on the function names in any open files and offers it in autocomplete. I’m doing PHP. So I start a session by opening my database and helper function files. Then any file I open gets full access to the autocomplete.

I prefer N++ but have been using Atom more lately because I’m doing a HUGE site update and the new function names are not in the old code. It’s saving me a TON of typing.
