Usage

Blame-tracker has several flags, but there are only a few you need to know about:

Important Flags

Short	Long	Args	Description
-i	--info	❌	Print info messages about the statistics related to the commits.
-d	--days-ago	int	Set or shift the start date for the collection of commits back by a number of days.
-t0	--since	An American formatted date like 1/31/1970 (January 31st, 1970), or an ISO 8601 formatted date.	Set the start date for the collection of commits.
-t1	--until	👆	Set the end date for the collection of commits.
-in	--include	One or more more file patterns.	Include one or more patterns of files. To include all C files in a given folder, you could do -in "folder/*.c" (or "folder/**/*.c" for recursion)
-ex	--exclude	👆	Exclude one or more patterns of files. You can do this on your build folders -ex build, or all markdown files -ex "**/*.md"
-by	--author	One or more authors' names.	This will filter the annotated output to only show code by the authors supplied.
-o	--output	The output path for the accused lines of code.	This flag is optional. This writes the relevant, annotated code to the output file according to the filters provided in the arguments.

Less Important Flags

These are flags that you probably won't need to use, but they're here if you need them.

Short	Long	Args	Description
-f	--format	A format string to print the accused code with.	The format arguments used are name (the name of the accused file), path (the path of the accused file), author (the author of the file), content (the line in the accusation), date (the date of the commit), and time (the time of the commit). The default format specifier is "{name:12} ({author} on {date} at {time}): {content}"
-w	--weeks-ago	int	Set or shift the start date for the collection of commits back by a number of weeks.
-r	--repo	A path to a Git repository.	Set the directory of the git repository to accuse. By default this is just the current directory.
-ws	--keep-whitespace	❌	Use this flag to keep whitespace lines in the output file.
-s	--silence-warnings	❌	Use this flag to silence warnings. This will allow bytes-like data to be accused and included in the output file silently. Don't use this if you don't wanna include massive binary files (which you probably don't).
-v	--verbose	1, 2, or 3	Set the verbosity level for printing out runtime information. 1 is the same as enabling --info.
-h	--help	❌	Print the help message.

Examples

Here are some examples of how to use blame-tracker.py:

# Print the blame for all C files (recursively) in the current repository.
blame-tracker.py -in "**/*.c"
# Print the blame for all C files (recursively) in another given repository
blame-tracker.py -r /path/to/repo -in "**/*.c"
# Print the blame for all C files in a `src` repository and exclude all markdown files in the current directory
blame-tracker.py -in "src/*.c" -ex "*.md"
# Print the blame for a specific author in the current directory
blame-tracker.py -by "Adam McDaniel"
# Print the blame for a specific author in the current directory and include all rust files (recursively), excluding all files in the `target` directory
blame-tracker.py -by "Adam McDaniel" -in "**/*.rs" -ex "target"
# Print a formatted blame for a specific author in the current directory and include all rust files (recursively), excluding all files in the `target` directory
blame-tracker.py -by "Adam McDaniel" -in "**/*.rs" -ex "target" -f "{name:12} {date} ({author}) {content}"
# Get the blame for a specific author in the current directory and include all rust files (recursively), excluding all files in the `target` directory, and write it the output to a file
blame-tracker.py -by "Adam McDaniel" -in "**/*.rs" -ex "target" -o output.txt

Installation

Requirements:

• Python 3.11

As a Script

You can run blame-tracker.py as a script by running python3 blame-tracker.py in the directory of the repository you want to blame.
