Show the value of a python object via command line.
Examples:
.. code-block:: bash
$ pyval sys.platform
linux
This is meant to provide a more convenient alternative to:
.. code-block:: bash
python -c "import sys; print(sys.platform)"
More complex expressions are possible too:
.. code-block:: bash
$ pyval math.pi**2
9.869604401089358
$ pyval 'math.sin(math.pi/4)'
0.7071067811865475
The output can be influenced using one of the following command line arguments:
=========================== ================================================
-r, --repr
Print repr(obj)
-j, --json
Print json.dumps(obj)
-p, --pprint
Print pprint(obj)
-f SPEC, --format SPEC
Print format(obj, SPEC)
=========================== ================================================
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.:
.. code-block:: bash
wget https://raw.githubusercontent.com/coldfix/pyval/master/val.py \
-O ~/.local/bin/pyval
Once 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.
