mdmerger is a simple CLI tool designed to simplify the process of merging multiple markdown files into a single document, automatically generating a Table of Contents (ToC) for better navigation. This tool was born out of a personal need to create a PDF documentation from an existing GitLab wiki. Unfortunately, existing solutions were either too complex or did not meet the specific requirements.

To use mdmerger, clone this repository to your local machine:

git clone https://github.com/yourusername/mdmerger.git
cd mdmerger
chmod +x mdmerger.sh

Run mdmerger by specifying the main title as the first argument, followed by the markdown files you want to merge:

./mdmerger.sh "My Merged Document" file1.md file2.md file3.md

This will create a new markdown file with your specified main title, a ToC, and the combined content of the provided files.

After creating your merged markdown document, you may wish to convert it to PDF. I successfully used the following command for my project documentation, relying on Pandoc and wkhtmltopdf:

pandoc merged_file.md -o merged_file.pdf --pdf-engine=wkhtmltopdf

This command requires having both Pandoc and wkhtmltopdf installed on your machine. You can install Pandoc by following the instructions on the official website. For wkhtmltopdf, you can download the latest release from the official website.
