who - Git Productivity Toolkit

gx who identifies the top contributors to your repo, file, or directory. The output format varies depending on whether you pass a file, directory, or nothing.

Usage

gx who [path] [flags]

Examples:

gx who                          # Top contributors (commits)
gx who src/auth.go              # Who owns this file (blame)
gx who src/                     # Who owns this directory
gx who --since 6months          # Only last 6 months
gx who src/ --since 2024-01-01  # Directory, since date

Flags

Flag	Short	Default	Description
`--number`	`-n`	5	Number of contributors to show
`--since`			Only consider contributions after this date (e.g., `6months`, `2024-01-01`, `yesterday`)
`--no-limit`		false	Remove file cap for directory analysis

Modes

Repo-level: `gx who`

When run with no arguments, shows contributors by commit count using git shortlog -sne HEAD:

$ gx who

 #  Author          Commits  Email
Sarah Chen          953  sarahchen@users.noreply.github.com
James Wilson        138  james.w@example.com
Alex Kim             45  alex.kim@example.com
Maria Lopez          19  maria.l@example.com
Pat Taylor           12  pat.t@example.com

File-level: `gx who <file>`

When given a file path, shows blame-based line ownership:

$ gx who src/auth.go

 #  Author          Lines    %  Email                             Last Edit
 1  Sarah Chen        120  54%  sarahchen@users.noreply.github..  2 weeks ago
 2  James Wilson       68  31%  james.w@example.com               1 month ago
 3  Alex Kim           34  15%  alex.kim@example.com              3 months ago

Directory-level: `gx who <dir>`

When given a directory, runs concurrent blame across all files (8 workers, capped at 200 files by default):

$ gx who src/

 #  Author          Lines    %  Files  Email                             
Sarah Chen       1420  48%     12  sarahchen@users.noreply.github..
James Wilson      830  28%      8  james.w@example.com
Alex Kim          450  15%      6  alex.kim@example.com
Maria Lopez       180   6%      3  maria.l@example.com
Pat Taylor         90   3%      2  pat.t@example.com

Use --no-limit to remove the 200-file cap for large directories.

More Examples

Show the top 10 contributors:

gx who -n 10

Analyze a specific directory with no file cap:

gx who src/ --no-limit

How it works under the hood

Repo mode (gx who): Runs git shortlog -sne HEAD to gather contributors on the current branch
File mode (gx who <file>): Runs git blame and aggregates lines per author, computing percentages and last edit timestamps
Directory mode (gx who <dir>): Runs git blame concurrently across files (8 workers, capped at 200 files unless --no-limit is set), then aggregates lines, percentages, and file counts per author
Results are sorted by commit count (repo mode) or line count (file/directory mode) descending
