[SOLVED] vim support for Python 3

davisd · 2012-01-19 19:48:05

I am trying to program with Python 3 and use the omnicompletion features of vim but I cannot even get a python 3 interpreter to work from within vim or gvim.

:python import sys; print(sys.executable)
/usr/bin/python2.7

and

:python3
E319: Sorry, the command is not available in this version

It looks as though vim needs compiled with python 3 support? I'm seeing in --version that it was passed the -python3 switch (as opposed to +python3)

I'm curious- since Python 3 has been the default python in Arch Linux for a while now- when will Python 3 support be included in the standard vim package?

Thanks!
-David

I'm not sure, but http://projects.archlinux.org/svntogit/ … ckages/vim

  cd "${srcdir}"/gvim-build

  ./configure --prefix=/usr --localstatedir=/var/lib/vim \
    --with-features=big --with-compiledby=ArchLinux \
    --enable-gpm --enable-acl --with-x=yes \
    --enable-gui=gtk2 --enable-multibyte --enable-cscope \
    --enable-netbeans --enable-perlinterp --enable-pythoninterp \
    --disable-python3interp --enable-rubyinterp --enable-luainterp

means there's no python3 support.

https://bugs.archlinux.org/task/25529 on the other hand suggests it's fixed.

Ok, I requested a re-open on that ticket... Strange that it was reported fixed 4 months ago, I wonder if it was fixed and reverted.

Thanks!

Enabled here: http://projects.archlinux.org/svntogit/ … 44832310d7
Disabled here: http://projects.archlinux.org/svntogit/ … e4f133fba3

It's one way to "Clean up configure options" ;-)

Ok, I found this from a few days ago: https://bugs.archlinux.org/task/27527

It looks like the package maintainer, Eric who "Doesnt use vim and doesn't really care" decided to yank vim support for Python 3.

Apparently there was a conflict between Python 2 and Python 3 in VIM and yanking Python 3 support looked like the solution.

It looks like it was a toss-up and they chose Python 2 support over Python 3 because it has more libraries.

I'll play with ABS and see what I can do.

Do you need python2 and python3 in one package?

davisd · 2012-01-19 20:41:18

I suppose not. Most of my projects are Python 2 but I'm transitioning to Python 3. I don't think I'll be working with both interpreters at once.

davisd · 2012-01-20 01:11:37

https://bugs.archlinux.org/task/25529

A Project Manager has denied the request pending for the following task:
FS#25529 - [gvim] compiled with -python3?
User who did this - Jan de Groot (JGC)
Reason for denial:
Enabling both python2 and python3 interpreter is not an option.

karol · 2012-01-20 01:14:47

Maybe you can just create python3-enabled vim package that conflicts with the stock one and install it when you are working with pythno3?

davisd · 2012-01-20 16:03:32

I got that working yesterday, but it's not optimal.

I'm going to play more with the ABS. This looks like a good opportunity for me to learn more about it.

My plan is to update the PKGBUILD for the current gvim package- and create a gvim-python3 package with a different installation prefix - /usr/local/ or even /opt/gvim-python3/

When I need to run for python3, I'll just use /opt/gvim-python3/bin/vim

I need to use gvim as a base.

Does that sound like a good solution or am I not considering something? I don't have experience with abs...

Thanks for the help, karol!

-David

karol · 2012-01-20 16:12:27

Yup, that should work too and is more flexible than what I was suggesting.

I was thinking about just the '--enable-pythoninterp' and '--enable-python3interp'. One package would be for python2, the other for python3 and you would install one and remove the other when you would need to switch python interpreters ;P

davisd · 2012-01-20 19:51:18

Ok, if anyone else is using vim or gvim with Python 3- here's a new PKGBUILD!

I'm just learning abs and I'm sure it's not perfect, but it should work fine until the next version and the source links break!

Make sure you have installed and refreshed abs and do:

$ cp -r /var/abs/extra/vim /var/abs/local/vim-python3

Replace /var/abs/local/vim-python3/PKGBUILD with:

$ mkdir ~/abs/
$ cp -r /var/abs/local/vim-python3 ~/abs/
$ cd ~/abs/vim-python3

...and pacman -U what you want.

It installs to /opt/vim-python3

vim-python3 and gvim-python3 symlinks are installed in /usr/local/bin/

karol · 2012-01-20 19:56:40

Why not

$ mkdir ~/abs/
$ cp -r /var/abs/extra/vim ~/abs/vim-python3
$ cd ~/abs/vim-python3
<edit PKGBUILD>
$ makepkg

I know this is unimportant but I don't get why do you copy it to /var/abs/local/vim-python3 first ;P

davisd · 2012-01-20 20:19:51

I was trying to keep /var/abs/local/vim-python3 clean and was building in ~/abs/vim-python3.

On my system, I'll probably toss ~/abs at some point but keep the /var/abs/local

But you're right, that probably doesn't matter to anyone else

OK, I get that different versions of python don't mix, but why is it that support for python2 (and ruby and lua) are enabled only for gvim?? Some of us are actually quite content with using only command line vim Is there some rationale behind this, or is it a bug? (or a whim?)

gvim package provides a vim binary. vim package is meant to be light and gvim package is meant to be full-featured.

Hi fellow Archers!

I too wandered in looking for python 3 support. It's disappointing that official repos gvim builds with python 2 as Arch is on the forefront of bleeding edge adoption usually. I've modified the official PKGBUILD to build with python 3 support and uploaded to AUR for the people who are still alive . https://aur.archlinux.org/packages.php?ID=61870. It should be working fine since I basically just changed some build flags, but if there's bugs, feel free to holler.

EDIT: I've also taken the time to fix ropemode/ropevim for Python 3. Python3ers, rejoice! /shameless plug
