Doom-emacs: Not working autocompletion in python-mode

[smdnv]

Observed behavior

I have in the settings

(require 'company)
(setq company-idle-delay 0.2
      company-minimum-prefix-length 3)

When I open *.py autocompletion not working.

Expected behaviour

Autocompletion works when I open the file the first time.

Steps to reproduce

1. Create and open test.py file
2. Run describe-variable company-backends. Its value is (company-capf company-dabbrev company-ispell company-yasnippet)
3. Run python-mode and again describe-variable company-backends. Current value is ((company-anaconda) company-capf company-dabbrev company-ispell company-yasnippet)

Found the issue and fixed it in develop. I'll keep this open until it hits master. Thanks for letting me know!

[Githeo]

I did a fresh install from the dev branch and still it doesn't work out of the box.

[Br1ght0ne]

@Githeo Did you enable both :completion company and :lang python (or the module for the programming language you are testing with)?

[Githeo]

Hello @filalex77, in the .doom/init.el file the:completion companywas already enabled and I enabled the :lang pythontoo. Still no completion.
Do I need to run some other commands before?

[Br1ght0ne]

Did you run doom refresh after enabling said modules? @Githeo

[Githeo]

just did it and I also add in the init.el

(require 'company)
(setq company-idle-delay 0.2
      company-minimum-prefix-length 3)

with no luck.

The only way so far to make it work is to disable global-company-mode and then to re-enable it at each time I open emacs. It's annoying.

the same problem.

[Br1ght0ne]

@alinbxSorcerer Is there any way you can get completion working (for example, by restarting global-company-mode)? If not, please try manually installing dependencies for anaconda-mode (the Python backend for Emacs used by :lang python):

pip install jedi json-rpc service_factory

Be sure to check your Python version (for example, to use pip3 for Python 3), whether you have permissions for a system-wide installation (sudo pip install or pip install --user may work, but please consult the documentation for your OS of choice).

If that doesn't help, please let me know, and also describe your environment in more detail. Pasting the output of M-x doom/info RET would be a good start. Good luck!

@Githeo There were some changes (not necessarily related to :lang python) since 2019-07-23, would you mind running doom update?

Also, lsp-python-ms support was added. Consider setting it up, LSP is objectively better than any company backend.

[Githeo]

@filalex77 I did the doom update. Now a completion is shown but it's the common one for all the variables only.
How could I switch to lsp-python-ms?

[Br1ght0ne]

@Githeo

1. Quit Emacs.
2. Add +lsp flag to :lang python in init.el

:lang
-python
+(python +lsp)

1. Run doom refresh.
2. Launch Emacs. Run M-x lsp-python-ms-setup RET to install the server (it may hang for a few minutes).
3. Try opening up a .py file and see what you get!

DISCLAIMER: this works only for files that are a part of a "project". Not sure on what a project is in terms of Python, but I just created a scaffold using poetry (poetry new my_app), and it worked with the files inside.

[Githeo]

lsp-python-ms-setup doesn't pop up after M-x. Is it not installed?

bin/doom install lsp-python-ms
