In pyenv 2.0 onwards, it is not enough anymore to initialize pyenv in
shell by just calling `pyenv init -`. We also need to update `path` to
include pyenv shims by calling `pyenv init --path`.
Also, honor `$PYENV_ROOT` if set but, no need to set it explicitly if
not set. Instead, let the initialization script take care of that.
Move `pip` to separate completion definition delegating to pip to do
all the completion work.
Since the completion is loaded lazily on-demand, it avoids the
performance overhead during Zsh initialization.
Implementation note:
The helper function `_pip_completion` implementation is based on the
official pip completion function (which can be generated with
`pip completion --zsh`) adhering to the newer compsys style.
See: 'man zshcompsys' for more details.
Zsh and Prezto files don't always reside in `~/`. Instead, they have
a more spec compliant location (`${ZDOTDIR:-$HOME}/`). Make them
unambiguous in the documentation. Likewise, for `$GNUPGHOME`.
Further, add instruction for optionally setting up Prezto in
`$XDG_CONFIG_HOME`.
While at this, also add clarification on relative ordering of some of
the modules, apply more formatting tweaks and doc improvements.
General purpose reformating and rewording in (a few places). This should
also make markdown linting happier.
Prefer back-ticks wherever useful and use `console` for code blocks to
be executed on terminal.
Also, update references links wherever possible (including update from
'http://' to 'https://').
* Added conda virtualenv support to python module
* Added instructions for Python module options to README
Thanks to @egpbos for the original feature and @ickc for fixing the merge conflicts.
Changes:
* Simplify zstyle name `skip-virtualenvwrapper-init` to `initialize`
avoiding double negation in name
* Always perform `eval (pyenv virtualenv-init -)` at initialization
* Prefer `virtualenvwrapper_lazy` over `virtualenvwrapper` when available
* Honor `VIRTUALENVWRAPPER_VIRTUALENV` if it is defined.
* Document about `VIRTUALENVWRAPPER_PYTHON` and `VIRTUALENVWRAPPER_VIRTUALENV`
(this would be particularly important in macOS after recent homebrew update)
* Add additional documentation for `initialize` in _README.md_ and _zpreztorc_
* Add aliases `py2`, `py3` as shortcut for `python2`, `python3` respectively
