how to install

grassloper is delivered as a simple pip application, and as such it can be installed from scratch using the following steps:

# create a python virtual environment (we name it name grassloper.venv)
bob@stykades:~/work/grassloper$ python3 -m venv grassloper.venv  
# activate the virtual environment to use it
bob@stykades:~/work/grassloper$ source ./grassloper.venv/bin/activate
# grassloper requires improtools https://github.com/g-raffy/improtools, which is not in pip's catalog
# install improtools from its source directory (./improtools.git here, downloaded from https://github.com/g-raffy/improtools)
(grassloper.venv) bob@stykades:~/work/grassloper$ pip install -e ./improtools.git
# install grassloper from its source directory (./grassloper.git here)
# this automatically installs the packages that grassloper depends on
(grassloper.venv) bob@stykades:~/work/grassloper$ pip install -e ./grassloper.git
# now that grassloper is installed in grassloper.venv and grassloper.venv is activated, simply run it using its command line 'grassloper'
