MacVim with pyenv

Gist guide for MacVim with Python 2.x and Python 3.x

On El Capitan worked version 7.4.1749 from 18.04.2016

git clone https://github.com/macvim-dev/macvim.git

if used rvm, need use any not system ruby interpretator

brew install gpg2
rvm install 2.3
rvm use 2.3

On El Capitan after install xcode, need run:

xcode-select --install

without this: ERROR: The Python zlib extension was not compiled. Missing the zlib?

pyenv interpretator must be builded with framework

env PYTHON_CONFIGURE_OPTS="--enable-framework CC=clang" pyenv install 2.7.11
env PYTHON_CONFIGURE_OPTS="--enable-framework CC=clang" pyenv install 3.5.1
pyenv global 2.7.11:3.5.1

lua from homebrew

brew install lua

export vi_cv_dll_name_python=/Users/svolkov/.pyenv/versions/2.7.11/Python.framework/Versions/2.7/Python
export vi_cv_dll_name_python3=/Users/svolkov/.pyenv/versions/3.5.1/Python.framework/Versions/3.5/Python

vi_cv_dll_name_python - you may set in the .vimrc befor first using python (load YouCompliteMe), after loading change interpretator not available. Build not supprort both python 2 and python 3 loaded simultaniosly:

E837: This Vim cannot execute :py3 after using :python
E263: Sorry, this command is disabled, the Python library could not be loaded.

Dynamic python interpretator not linked to the bin, for static linked interpretator need change link with otool:

# check libs
otool -L src/MacVim/build/Release/MacVim.app/Contents/MacOS/Vim
# replace system python framework
install_name_tool -change \
/System/Library/Frameworks/Python.framework/Versions/2.7/Python \
/Users/svolkov/.pyenv/versions/2.7.10/Python.framework/Versions/2.7/Python \
src/MacVim/build/Release/MacVim.app/Contents/MacOS/Vim

test build

:python import sys; print(sys.version)

open src/MacVim/build/Release/MacVim.app
src/MacVim/build/Release/MacVim.app/Contents/MacOS/Vim --version

YouCompleteMe

brew install cmake
cd ~/.vim/bundle/YouCompleteMe
./install.py --clang-completer --gocode-completer

If MacVim was not compilled on this machine, in the start .vimrc need insert:

set pythondll=/Users/<username>/.pyenv/versions/2.7.11/Python.framework/Versions/2.7/Python
