    it should be slow only for the first time it discovers an object. If you use certain objects more often
    then others, you could try to preload them jedi.preload_module(['os','sys', ...])

      Thanks for the tip! Python is obviously not my strength; hence, the want for some “IDE-lite” help from Notepad++.

      Cheers.

          Microsoft Language Server Protocol (LSP) defines the protocol used between an editor or IDE and a language server that provides language features like autocomplete, go to definition, find all references etc.:

            ok, this is my “lsp” script (called python_ide.py)

            I wonder if this pylspclient can be used? It’s supposedly an LSP client written in Python so theoretically PythonScript could run it.

            I’ve been playing with it from the command line with my system Python3 and not having much luck with the examples/python-language-server.py script included and having the python-language-server installed.

            Cheers.

              let me have a look and play with it a bit.

                It looks like the main problem might be that this lspclient is written for Python2.
                Let me see if I can make a working version. Probably in 6-7 hours.

                  Weird - it seems to “run” OK - not throwing any errors, but just not initializing with the language server:

                    @Michael-Vincent - I tried to make it work but after three
                    Npp crashes I decided to make my implementation work with python3.
                    I’ll keep working on it an updates will be made available via the github repo.

                      I’ll keep checking back then - thanks!

                        A plugin implementing an LSP client in Notepad++ has finally been released.

                        https://github.com/Ekopalypse/NppLspClient

                        Credits to @Ekopalypse for that.

                        I encourage everyone to give it a try and report back for any found issue.

                          … but bear in mind that this is in an early alpha stage and that there is another plugin that already covers some pitfalls when it comes to implementing LSP for Npp and Scintilla.
