Project description
GENENV
This command line utility tool allows you to create python virtual environements with already installed dependencies you want easily!
Features
- You can create virtual environments with pre-installed packages that you specify in command line
- Instead of providing package name on command line, you can add a
template.txt
file containing names of packages you want intalled - Install packages in already existing virtual environments without having to activate them
- you can create virtual environments with no packages installed.
How it works
Essentially, the process of virtual environments creation and installation of packages is done in the bash script .createnv.sh
.
The bash script is called as a subprocessin the python file.
Click
is used to provide a CLI interface and collect arguments from the command line to pass into bash script when
its being called.
Usage
- Install with pip
pip install genenv
NOTE:
- if you specify package names on command line and template.txt file exits ,template.txt file will be ignored.
- if no template.txt file or package name(s) are provided as on command line as arguments, you'll recieve prompt if you still want to proceed to create virtual environment with no preinstalled dependencies.
- To use contents of
template.txt
file , do not provide any package names after you specify environment name
Creating a virtual environment with name meseeks
with django and flask installed
- specifying dependecies on command line
genv -n meseeks flask django
Creating a virtual environment with name meseeks
with dependencies specified in template.txt
file
- create a file with name
template.txt
in same directory you will run command - Add package names to it
genv -n meseeks
It detects and reads contents template.txt
file
then installs package names specified inside.
If template.txt
file is available and empty, environemnt is created with no installed dependencies.
Installing dependecies/packages in already existing virtual environment
- specify the name option flag as the name of the environment you want to install package in
- if you want to install numpy in an existing virtual environment called
pluto
make sure youre in directory that venv is located then run
genv -n pluto numpy
- run
genenv --help
to bring up help menu
Usage: genenv [OPTIONS] [DEPENDENCIES]...
specify package names after name flag to install them,read documentation for
how that works
Options:
-n, --name TEXT provide name to be used for your virtual environment
[required]
--help Show this message and exit.
