Show value of an importable object
Project description
Show the value of a python object via command line.
Examples:
$ pyval sys.platform
linuxThis is meant to provide a more convenient alternative to:
python -c "import sys; print(sys.platform)"More complex expressions are possible too:
$ pyval math.pi**2
9.869604401089358
$ pyval 'math.sin(math.pi/4)'
0.7071067811865475Installation
The utility can be installed as follows:
pip install --user eval
It is also possible to simply download val.py and symlink or move under the name of your choice into your PATH, e.g.:
wget https://raw.githubusercontent.com/coldfix/pyval/master/val.py \
-O ~/.local/bin/pyvalOnce either of these is done, it can be used within any python enviroment on your system, as long as it is accessible in PATH.
By default it uses the currently activated environment. In order to use it with unactivated python interpreter, you currently have to call the interpreter manually as follows:
/path/to/python ~/.local/bin/pyval 'math.sin(math.sin/3)'
This module is kept deliberately simple and avoids any dependencies not in the standard library. This allows running the script in any python environment once it is installed on the system, without having to install it in each environment individually.
