List Virtual Environments for virtualenvwrapper

If you use virtualenvwrapper you’ll love this :)

Due to virtualenvwrapper’s lsvirtualenv’s super slow speed and lack of information, I made this simple cli-tool with golang.

---

Requirements

I’m assuming that you are already using virtualenvwrapper and you have WORKON_HOME environment variable is already exists in your shell environment.

---

Installation

You can install from the source;

$ go install github.com/vigo/lsvirtualenvs@latest

This will build and install binary of lsvirtualenvs under $GOPATH/bin path.

or, you can install from brew:

$ brew tap vigo/lsvirtualenvs
$ brew install lsvirtualenvs

Build from source

Check your go env GOPATH then check sources;

$ ls "$(go env GOPATH)/src/"
cloud.google.com  github.com  go.opencensus.io  golang.org  google.golang.org

# if github.com does not exists, create the folder via
# $ mkdir "$(go env GOPATH)/src/github.com"

$ mkdir "$(go env GOPATH)/src/github.com/vigo" # need for run/build operations
$ cd "$(go env GOPATH)/src/github.com/vigo"
$ git clone git@github.com:vigo/lsvirtualenvs.git
$ cd lsvirtualenvs/
$ go build
$ ls "$(go env GOPATH)/bin" # you should see `lsvirtualenvs` binary
$ lsvirtualenvs -h

Usage

$ lsvirtualenvs -h

usage: lsvirtualenvs [-flags]

lists existing virtualenvs which are created via "mkvirtualenv" command.

  flags:

  -c, -color          enable colored output
  -s, -simple         just list environment names, overrides -c, -i
  -i, -index          add index number to output
      -version        display version information (X.X.X)

Usage examples:

$ lsvirtualenvs -h
$ lsvirtualenvs -c
$ lsvirtualenvs -color
$ lsvirtualenvs -c -i
$ lsvirtualenvs -color -index
$ lsvirtualenvs -s
$ lsvirtualenvs -simple

Example output:

$ lsvirtualenvs
you have 2 environments available

textmate................... 3.8.0
trash...................... 3.8.0

$ lsvirtualenvs -i
you have 2 environments available

[0001] textmate................... 3.8.0
[0002] trash...................... 3.8.0

$ lsvirtualenvs -c -i # colored output with index

Run tests via;

$ go test -v ./...

Docker

https://hub.docker.com/r/vigo/lsvirtualenvs/

Note that, lsvirtualenvs requires WORKON_HOME environment variable which is not available inside of the docker container :) This is just an example / concept of dockerized version of the application :)

$ docker run --read-only -v "${WORKON_HOME}":/venvs --env WORKON_HOME=/venvs vigo/lsvirtualenvs
$ docker run --read-only -v "${WORKON_HOME}":/venvs --env WORKON_HOME=/venvs vigo/lsvirtualenvs -h

If you run it from container, currently, it’s not possible to get python versions of the existing environments.

Rake Tasks

$ rake -T

rake default            # show avaliable tasks (default task)
rake docker:lint        # lint Dockerfile
rake release[revision]  # release new version major,minor,patch, default: patch
rake test[verbose]      # run tests
