virtualenv-mgr

virtualenv-mgr is a tool to manage multiple virtualenvs at once.

Use a file with paths to the root of multiple virtualenvs to perform operations in all of them at the same time.

Features

• Install, uninstall or upgrade specific packages in all virtualenvs at once.
• Print statistic, a histogram, about the usage of packages over all environments.
• Find/list virtualenvs for further processing, eg. as input for virtualenv-mgr
• Find all envs having a package installed

Installation

pip install virtualenv-mgr

Usage

Find environments with -z/--envfreeze

Find all virtualenvs ar your current location / subdictionarys (look for the '/bin/activate' pattern)

virtualenv-mgr --envfreeze
virtualenv-mgr -z

Define a searchroot, where the scrip should search in:

virtualenv-mgr --envfreeze --searchroot /Users/name/workspace/2014
virtualenv-mgr -zs /Users/name/workspace/2014

Save the paths to a file which you can use later.

virtualenv-mgr -zs /Users/name/workspace/2014 > example-env-file.txt

Define Environments

Environments from a list:

virtualenv-mgr example-env-file.txt

Or input over a pipe:

virtualenv-mgr --envfreeze | virtualenv-mgr

Manualy define environments, use "," to seperate the paths (-m, --multiple)

virtualenv-mgr -m=/absolute/path,relative/path/,../../env

No arguments --> active virtualenv

virtualenv-mgr

Actions

Install a package / multiple packages

virtualenv-mgr example-env-file.txt -i "django==1.4.16,djangotransmeta"

Uninstall a package / multiple packages

virtualenv-mgr example-env-file.txt -u "django==1.4.16"

Find packages / multiple packages (can look for exact packages '==' or if the package is installed)

virtualenv-mgr example-env-file.txt -f "django==1.4.6"

Install or Uninstall packages in envs where certain other packages are installed.

virtualenv-mgr example-env-file.txt -f "django==1.4.12" -i "django==1.4.16" -u "django-transmeta"

All virtual-environments which have installed django==1.4.12 will install django==1.4.16 and uninstall django-transmeta.

Pip Option

pipoption allows you to add options to the pip commands ( install / uninstall ) , use the ',' to separate multiple commands

virtualenv-mgr example-env-file.txt -i django==1.4.18 -o='--index-url=http://pypi.example.com/pypi,--extra-index-url=http://pypi.python.org/simple'

Env Diff

You can print table that displays the differences of the installed packages in multiple virtualenvs (-d, --diff)

virtualenv-mgr compare-envs.txt -d

Filter: Apps that are not installed on all virtualenvs (-n, --notinstalled, -dn)

virtualenv-mgr compare-envs.txt -n

Filter: Apps that dont have the same version in all virtualenvs (-a, -versiondiff, -da)

virtualenv-mgr compare-envs.txt -a

Combine (-an , -dna)

virtualenv-mgr compare-envs.txt -na

Neglects eggs

Pip Histo

print the pip histo (overview over all installed packages) (-p,--piphisto)

virtualenv-mgr example-env-file.txt -p

Distinguishes between different versions (-v,-version ; -pv)

virtualenv-mgr example-env-file.txt -v

Take eggs into the histo (-e,-egg ; -pe)

virtualenv-mgr example-env-file.txt -e

Combine (-ve, -pve)

virtualenv-mgr example-env-file.txt -ve

Help

Envfreeze:

• -z, --envfreeze prints all the envs on .
• -s SEARCHROOT, --searchroot SEARCHROOT path for envfreeze, where to search
• -m MULTIPLE, --multiple MULTIPLE Add paths to envs, sepereate with ","

Actions

• -f FIND, --find FIND find app, use commas to search for more
• -i INSTALL, --install INSTALL installes an app, use commas to add more
• -u UNINSTALL, --uninstall UNINSTALL uninstalles an app, use commas to add more

Pip Option

• -o, --pipoption allows you to add options to the pip command(-i/--install and -u/--uninstall)

Env Diff

• -d, --diff commpares the packages installed in envs
• -n, --notinstalled lists apps that are not installed on all envs
• -a, --versiondiff lists apps that dont have the same version number on all envs

Pip Histo

• -p, --piphisto pip histogram
• -e, --egg pip histogram takes eggs into consideration
• -v, --version pip histogram takes versions into consideration
