Python library: pyexpander

Installing pyexpander

In my case as administrator on Windows:

pip install pyexpander

This also installs the expander.py script under <inst-dir>/Scripts.

Here's a file to be preprocessed (test.txt):

first $py(num = 42) line
second $py(txt = 'Hello world') line

This is the fourth line in the output.

The number is $(num) and the text is $(txt).

This file can now be preprocessed to stdout with

C:\users\rene> expander test.txt

This command prints

first  line
second  line

This is the fourth line in the output.

The number is 42 and the text is Hello world.
