pyv

Description

pyv is an utility to manage python distributions and related virtualenvs

Example

% pyv l
# distributions
 from_path:Python 3.6.6:/home/thomas/local/pyv/venvs/default/bin
 Python-2.7.14:Python 2.7.14:/home/thomas/local/pyv/distributions/Python-2.7.14
 Python-3.6.8:Python 3.6.8:/home/thomas/local/pyv/distributions/Python-3.6.8
 Python-3.7.0:Python 3.7.0:/home/thomas/local/pyv/distributions/Python-3.7.0
*Python-3.7.2:Python 3.7.2:/home/thomas/local/pyv/distributions/Python-3.7.2

# virtualenvs
*default:Python 3.6.8:/home/thomas/local/pyv/venvs/default
 EasyAVR:Python 3.6.8:/home/thomas/local/pyv/venvs/EasyAVR
 test:Python 3.6.8:/home/thomas/local/pyv/venvs/test

Command

pyv link

create venv ($1) symlink for the current or specified pyv venv ($2).

usage is : pyv link [venv target name] [pyv venv name]

• venv target name, by default is venv
• pyv venv name, by default is the current pyv virtualenv

% pyv l
[...]
*test:[....]
[...]
% pyv link
% ls -l
venv -> /home/thomas/local/pyv/venvs/test
% pyv link .env
% ls -l
.env -> /home/thomas/local/pyv/venvs/test
venv -> /home/thomas/local/pyv/venvs/test

Special Variables

PYV_BUILD_DISTS

You can use custom distribution that can be used to build Python with.

For example, during build process, you can force the openssl distribution to use, by setting the PYV_BUILD_DISTS variable.

After a build of openssl:

./config --prefix=/usr/local/openssl-1.1.1v --openssldir=/usr/local/openssl-1.1.1v/ssl
make
make install

You can use the custom openssl build with:

PYV_BUILD_DISTS=/usr/local/openssl-1.1.1v pyv build 3.9.18

To build with many specific distribution you can separate each custom lib with a ':' :

PYV_BUILD_DISTS=/usr/local/openssl-1.1.1v:/custom/path/sqlite-3440000 pyv build 3.9.18
