A python package to preprocess text files with embedded Python code snippets: evaluate or execute them and replace with the result of evaluation/execution.
This package provides the ppp.py script. The script reads the file
specified in the command line, finds python snippets, evaluates or executes
them and writes out the file with the pyhton code replaced with the
evaluateion/execution result.
The following example shows a template file (i.e. the file to be processed with ppp.py) and the result.
| Template (test/t1.t) | Resulting file (test/t1.res.t) |
|---|---|
`` The characters on the 1-st line define the delimiters, used to mark the python snippets. In this case, both the begin of the snippet and its end are denoted with the backtick. This is an evaluation snippet: `2*7`, and this is an execution snippet: `from math import pi; pi2=pi*2`. Check that the definitions made in the previous snippets are accessible: `pi2`. |
The characters on the 1-st line define the delimiters, used to mark the python snippets. In this case, both the begin of the snippet and its end are denoted with the backtick. This is an evaluation snippet: 14, and this is an execution snippet: `from math import pi; pi2=pi*2`. Check that the definitions made in the previous snippets are accessible: 6.28318530718. |
The package is published on PyPI: https://pypi.org/project/twps/. The preffered way to install is:
>pip install twps
For command line options see readme.rst in the twps folder or run the
script without command line arguemnt.
