A minimal Python + Fire + PEX app. As it sits, you could use it to help you build portable cli tools. All the compiled file needs is a Python environment.
Clone this repo, cd to repo folder.
Setup a venv here if you want
Install pex, fire (pip3 for me): pip3 install pex fire
From the firepex's root, run fireapp 'normally': python3 fireapp... should print:
user@user-pc:~/firepex$ python fireapp
Type: Example
String form: <__main__.Example object at 0x7f8c6acc94a8>
File: ~/repos/firepex-github/fireapp/__main__.py
Docstring: Example for firepex
Usage: fireapp
fireapp r-class
fireapp r-string
run rollpex, a quick n' dirty bash script to create a wheel, build the pex file, and chmod +x the resulting firepex file.
run: ./firepex; should print:
user@user-pc:~/firepex$ ./firepex
Type: Example
String form: <__main__.Example object at 0x7fede8977f28>
Docstring: Example for firepex
Usage: firepex
firepex r-class
firepex r-string
Play around with the cli and check out Fire! It's great!
./firepex runs likes a script..
user@user-pc:/firepex$ head -n1 firepex
#!/usr/bin/env python3.6
In this case, the shell looks for Python 3.6. I need that in the deployed environment to run firepex, but all my dependencies are included.
When you run ./rollpex, the #! is determined from your current python environment OR it can be overridden with a flag in Pex.
Fin.
