A simple tool to generate a call graph for calls within Windows CMD (batch) files.

The tool is available on PyPI: https://pypi.org/project/cmd-call-graph/

It takes the input file as stdin and outputs the resulting file to stdout,
outputting logs and errors to stderr.

Usage example from WSL (Windows Subsystem for Linux):

$ pip install cmd-call-graph
$ cmd-call-graph < your-file.cmd > your-file-call-graph.dot 2>log

The resulting `dot` file can be rendered with any `dot` renderer. Example with
graphviz:

$ sudo apt install graphviz
$ dot -Tpng your-file-call-graph.dot > your-file-call-graph.png
$ explorer.exe your-file-call-graph.png

## Example

Here is an example CMD script:

@echo off
call :foo
goto :eof
:bar
echo "in bar"
call :baz
call :baz
:baz
echo "in baz"
:foo
echo "In foo"
goto :bar

This script would generate the following graph:


If the `--show-all-calls` option is set to `True`, then the following graph would be generated:



## Why?
Sometimes legacy code bases may contain old CMD files. This tool allows to
generate a visual representation of the internal calls within the script.
