• Integrate git diffs with word docx files

Although we can use git to track changes in almost any file, including binary files like .docx files, it is difficult to visualize the changes made to these files.

I’ve put together simple instructions that you can use to visualize changes using git diffs.

• Add pre-commit and post-commit hooks to keep a Markdown (.md) copy of all .docx files inside this repository. This allows you to use git diffs to show the changes in the document, which can be viewed in the terminal, on the repository's commit page, in emails, or in other places that support git diffs.

• You must install Pandoc (https://pandoc.org/) on your machine. Run pandoc -v in your terminal to check if it is available.

1. Clone this repository:

   It is recommended to include --depth=1 so your new repository will have a fresh history.

   Replace FOLDER_NAME with your directory name:

   git clone --depth=1 https://github.com/farhan-syah/git-docx.git FOLDER_NAME
   cd FOLDER_NAME

2. Copy the hooks into the .git/hooks directory:

   cp -R hooks/* .git/hooks/

3. Update the local Git configuration to enable Pandoc-based diffs for .docx files and add a useful alias for word-diff:

   Run the following commands inside the repository to update the local Git configuration:

   git config diff.pandoc.textconv "pandoc --to=markdown"
   git config diff.pandoc.prompt false
   git config alias.wdiff "diff --word-diff=color --unified=1"

   These settings will:

   • Convert .docx files to Markdown when generating diffs.
   • Disable the prompt when using Pandoc for diffs.
   • Create a wdiff alias for word-diff mode with colored output.

4. Create or modify the .docx files using proper .docx software, like Microsoft Word or LibreOffice.

   WARNING: Do not create or modify the .docx files using terminal or common text editors that have no .docx support, as it will break the file and pandoc will fail to read it. Remember, .docx is a binary file and not a normal text file.

   For UNSTAGED changes, you can view the difference directly by using git wdiff. Please note that you'll see empty file when running this command on staged or commited files.:

   git wdiff FILENAME.docx

   or you can simpy use git gui blame for both STAGED or UNSTAGED:

   git gui blame FILENAME.docx

5. Stage and commit the files:

   git add FILENAME.docx
   git commit -m "Amend FILENAME.docx"

   When you stage the documents and create a new commit, a copy of the files in .md will be created/updated, and you can utilize git tools to view the changes.

To view the history of changes made to the .md files (which are the Markdown copies of your .docx files), you can use a few different Git commands. Here’s how:

1. Using git log to View the History

   The git log command is the most straightforward way to view the commit history of a file:

   git log -- FILENAME.md

   Replace FILENAME.md with the name of the Markdown file you want to inspect. This command will show the commit history for that specific file.

2. Viewing Differences with git log -p

   If you want to see the actual changes made to the file in each commit, you can use:

   git log -p -- FILENAME.md

   This will show you the commit messages along with the differences introduced in each commit.

3. Using git diff to Compare Versions

   If you know the specific commits or branches you want to compare, you can use git diff:

   git diff COMMIT1 COMMIT2 -- FILENAME.md

   Replace COMMIT1 and COMMIT2 with the commit hashes or branch names you want to compare. This will show you the changes between the two versions of the file.

4. Using git wdiff for Word-Level Diffs

   If you set up the wdiff alias (as previously discussed), you can use it to view word-level differences in the .docx files:

   git wdiff COMMIT1 COMMIT2 -- FILENAME.docx

   This will give you a more granular view of the changes, highlighting individual word changes within the lines.

5. Viewing History in a GUI

   If you prefer a graphical interface, you can use tools like gitk, GitHub Desktop, VSCode Git Extensions or any Git client that supports visual diffs. For example:

   gitk FILENAME.md

   This command opens a graphical history viewer for the specific file, showing commits and diffs visually.

• View commit history: git log -- FILENAME.md
• View commit history with diffs: git log -p -- FILENAME.md
• Compare two versions: git diff COMMIT1 COMMIT2 -- FILENAME.md
• Word-level diffs: git wdiff COMMIT1 COMMIT2 -- FILENAME.docx
• GUI view (gitk): gitk FILENAME.docx or gitk FILENAME.md
• GUI view (git gui): git gui blame FILENAME.docx or git gui blame FILENAME.md

These commands will help you track and inspect the history of changes made to your Markdown files in the repository.
