Convert Git commits to a PDF

commits2pdf

Visualise a Git repository's commit history in PDF form via the command-line

Dependencies

GitPython fpdf progressbar pathvalidate

pycairo (used for deprecated PDF generation method, must be installed manually)

Installation

requires pip

If using python or pip doesn't work, try using python3 or pip3

• Make a virtual environment and activate it (recommended):
  • Before you make a virtual environment, you should change your current directory to the folder of your repository. If you don't know how, read Changing your terminal's directory.

pip install virtualenv
python -m venv venv
MacOS/Unix: source venv/bin/activate
Windows: venv\scripts\activate

• Install the package in your system directory/virtual environment:

pip install -U commits2pdf

or, install the package in your home directory if you aren't using a virtual environment:

pip install --user -U commits2pdf

• You can deactivate your virtual environment when you are done:

deactivate

Changing your terminal's directory

• Open your terminal
• Find your repository's folder
• On Windows/Linux: Open the folder, press CTRL+L, then press CTRL+C
• On MacOS: Right click on the folder, hold option (⌥) and click Copy <folder name> as Pathname

Then, in your terminal, type cd <the path you copied> (paste in the path with CTRL+V or CMD+V).

Command-line parameters

There are many ways to configure the process of PDF generation through command line flags. For a brief introduction on how to use these flags, read Usage

-n, --name : The name of your outputted PDF file. Set to <repo_name>-commit_report by default.

-b, --branch : The repository branch. Set to main by default.

-d, --dark : Toggle dark mode for the output PDF. Set to light by default.

-po, --prevent-open : Prevent commits2pdf from automatically opening the directory the PDF was created in.

-sc, --scaling : Set the scaling of the output PDF. Only available with -gen2a and -gen2b.

-in, --include : Include commits with the given string sequences in their title or description. Format: <string1> OR <string1,string2>. Whitespace sensitive and case insensitive. NOTE: This query is performed BEFORE excluding commits.

-ex, --exclude : Exclude commits with the given string sequences in their title or description. Format: <string1> OR <string1,string2>. Whitespace sensitive and case insensitive.

-q, --quiet : Suppress all logger messages except for errors.

-gen1, --pdf-gen-1 : PDF rendering implementation with pycairo.

-gen2a, --pdf-gen-2a : The first PDF rendering implementation with fpdf.

-gen2b, --pdf-gen-2b : The second PDF rendering implementation with fpdf. The default option.

-rp RPATH, --repo-path : Path to your repository directory. Set to . (your current directory) by default.

-fc, --repo-from-clone : Clone a repo into the working directory and generate the commits PDF from it automatically. Format: <repo name> (case insensitive).

-nc, --newest-n-commits : Select the newest n number amount of commits to include after filtering.

-oc, --oldest-n-commits : Select the oldest n number amount of commits to include after filtering.

Usage

• Tip: If the value you are providing for a given argument/flag includes spaces, wrap in it quotations ("") to ensure it is parsed properly.

Usage example #1

c2p tomasvana10

Output a PDF to your current directory (assuming it is a git repository that is owned by tomasvana10).

Usage example #2

c2p tomasvana10 -o .. -rp ./my_repo -n "new_name.pdf"

Output a PDF (overriding its name to new_name) to the parent directory, selecting ./my_repo as your git repository to access the commits from.

Usage example #3

c2p tomasvana10 -nc 10 -in "javascript,build" -ex "testing"

Output a PDF to the current directory, displaying the newest 10 commits after filtering commits that contain "javascript" and/or "build in their title or description and do not contain "testing".

Usage example #4

c2p devguarv -fc Yr-12-HSC-SDD-Task-2 -e 28/4/2024

Clone the repo Yr-12-HSC-SDD-Task-2 into the current directory and output a PDF into the same place after filtering commits that were made up to 28/4/2024.

PDF generation implementations

pycairo (gen1 - deprecated)

👍 Fast
👎 Cannot write multipage commits
👎 Looks like crap
👎 No hyperlinks, therefore the entire link to a commit's diff is displayed

fpdf (gen2a)

👍 Fast
👍 Can be scaled with the -sc <float> argument
👍 Sleek design
👍 Information title page
👍 Contains hyperlinks
👍 Stores PDF metadata
👎 Inconsistent page breaks, a general limitation with FPDF when trying to fit as many whole commits on a single page

fpdf (gen2b - Default)

👍 Same as gen2a but with accurate page breaking
👎 Slow when generating large amounts of commits (generally, it is a good idea to enable -gen2a when drawing over 5000 commits)
