librep 0.0.4

Python-based command line tool to replace text/code in files

librep - LIne Block REPlacement

librep is a python-based command-line tools allows to render file placeholders. It replaces a placeholder of a given syntax with the content of the file that is specified in the placeholder.

The tool is independent of the document type, since it is assumed that the chosen syntax does not interfere with the syntax of any (especially markup) language.

The indentation of the placeholder is used for the whole inserted code/text block.

Usage

Insert a placeholder of the following syntax inside a file:

§§§<filename>:<start>:<end>§§§

Afterwards, you can render the placeholder by running

$ librep -i "file_with_placeholder.md"

This will replace the original line in the file file_with_placeholder.md with the content of the file <filename> from line <start> to line <end>. The filename has to either be absolute or relative to the file you specify the placeholder in.

Using a URL instead of a file from the repository

If you want to link a file that is not present on your machine, but you have a URL to that exact file, you can use the following syntax:

§§§url="<url>":<start>:<end>§§§

Note that this requires wget to be installed on your machine

Example

This file file_with_placeholders.md

# Heading

```py
§§§./code.py§§§
```

Can be processed with librep by doing

$ librep -i "file_with_placeholder.md"

Which results in

def calc_sum(a, b):
    """Calculates the sum of a+b
    Parameters
    ----------
    a : float, int
