| 1 | +# Stop Committing with the Wrong Git Identity |
| 2 | + |
| 3 | +We've all done it. You finish a feature, push it, and then realize you just committed to your client's repo as `Jane Doe <jane@personal.com>` instead of `Jane Dev <jane@company.com>`. |
| 4 | + |
| 5 | +Or worse — you opened a PR to an open-source project and your work email is now public forever. |
| 6 | + |
| 7 | +Managing multiple git identities is a solved problem that nobody has solved cleanly. Until now. |
| 8 | + |
| 9 | +--- |
| 10 | + |
| 11 | +## The old ways |
| 12 | + |
| 13 | +**Option 1: Edit `~/.gitconfig` before every project** |
| 14 | + |
| 15 | +```bash |
| 16 | +git config --global user.email jane@company.com |
| 17 | +# ... do some work ... |
| 18 | +git config --global user.email jane@personal.com |
| 19 | +# ... forget to switch back ... |
| 20 | +``` |
| 21 | + |
| 22 | +You will forget. Every time. |
| 23 | + |
| 24 | +**Option 2: `includeIf` in `~/.gitconfig`** |
| 25 | + |
| 26 | +```ini |
| 27 | +[includeIf "gitdir:~/work/"] |
| 28 | + path = ~/.gitconfig-work |
| 29 | +[includeIf "gitdir:~/personal/"] |
| 30 | + path = ~/.gitconfig-personal |
| 31 | +``` |
| 32 | + |
| 33 | +Works if every project lives in a tidy folder structure. Mine don't. Yours probably don't either. |
| 34 | + |
| 35 | +**Option 3: Set it per-repo, manually, every time** |
| 36 | + |
| 37 | +```bash |
| 38 | +git clone git@github.com:company/project.git |
| 39 | +cd project |
| 40 | +git config user.name "Jane Dev" |
| 41 | +git config user.email "jane@company.com" |
| 42 | +# also need to set core.sshCommand if using per-identity SSH keys... |
| 43 | +# and user.signingkey if GPG signing... |
| 44 | +``` |
| 45 | + |
| 46 | +Four commands every single time. That's not a workflow, that's a tax. |
| 47 | + |
| 48 | +--- |
| 49 | + |
| 50 | +## A better way: `git-profile` |
| 51 | + |
| 52 | +`git-profile` is a small CLI tool I built in Go that lets you define named identity profiles and apply them to any repo with a single command. |
| 53 | + |
| 54 | +```bash |
| 55 | +# One-time setup |
| 56 | +git-profile add --id work --name "Jane Dev" --email jane@company.com |
| 57 | +git-profile add --id personal --name "Jane Doe" --email jane@example.com \ |
| 58 | + --ssh-key ~/.ssh/id_ed25519_personal |
| 59 | + |
| 60 | +# Per repo, one command |
| 61 | +git-profile use work |
| 62 | +``` |
| 63 | + |
| 64 | +That's it. It sets `user.name`, `user.email`, `core.sshCommand`, `user.signingkey`, and `commit.gpgsign` all at once, only for that repo. |
| 65 | + |
| 66 | +--- |
| 67 | + |
| 68 | +## What it looks like day-to-day |
| 69 | + |
| 70 | +```bash |
| 71 | +$ git-profile list |
| 72 | + |
| 73 | + PROFILE USER EMAIL SSH KEY |
| 74 | + ────────────────────────────────────────────────────────────── |
| 75 | + personal Jane Doe jane@example.com ~/.ssh/id_ed25519_personal |
| 76 | +● work Jane Dev jane@company.com (default) |
| 77 | + |
| 78 | +$ git-profile current |
| 79 | + |
| 80 | + Current git identity |
| 81 | + |
| 82 | + user.name Jane Dev |
| 83 | + user.email jane@company.com |
| 84 | + ssh-key (default) |
| 85 | + |
| 86 | + Matched profile: work |
| 87 | +``` |
| 88 | + |
| 89 | +The `●` shows which profile matches your current repo's identity. |
| 90 | + |
| 91 | +--- |
| 92 | + |
| 93 | +## The "set it and forget it" mode |
| 94 | + |
| 95 | +The best feature: git hooks that automatically apply the right profile before every commit and push. |
| 96 | + |
| 97 | +```bash |
| 98 | +cd my-work-project |
| 99 | +git-profile install-hooks |
| 100 | +git-profile set-default work |
| 101 | +``` |
| 102 | + |
| 103 | +Now `git commit` in that repo always uses the `work` profile. No more thinking about it. |
| 104 | + |
| 105 | +You can also set a global fallback: |
| 106 | + |
| 107 | +```bash |
| 108 | +git-profile set-default personal --global |
| 109 | +``` |
| 110 | + |
| 111 | +Any repo without an explicit default falls back to `personal`. |
| 112 | + |
| 113 | +--- |
| 114 | + |
| 115 | +## GPG signing per identity |
| 116 | + |
| 117 | +If you sign commits, you probably have different GPG keys per identity. `git-profile` handles that too: |
| 118 | + |
| 119 | +```bash |
| 120 | +git-profile add --id work \ |
| 121 | + --name "Jane Dev" \ |
| 122 | + --email jane@company.com \ |
| 123 | + --gpg-key "ABC123DEF456" \ |
| 124 | + --sign-commits |
| 125 | +``` |
| 126 | + |
| 127 | +When you run `git-profile use work`, it sets all four keys at once: |
| 128 | + |
| 129 | +```ini |
| 130 | +user.name = Jane Dev |
| 131 | +user.email = jane@company.com |
| 132 | +user.signingkey = ABC123DEF456 |
| 133 | +commit.gpgsign = true |
| 134 | +``` |
| 135 | + |
| 136 | +--- |
| 137 | + |
| 138 | +## Already have git configured? Import it |
| 139 | + |
| 140 | +```bash |
| 141 | +git-profile import --id work --global |
| 142 | +``` |
| 143 | + |
| 144 | +Reads your current `~/.gitconfig` (name, email, SSH command, signing key) and creates a profile from it. Zero re-typing. |
| 145 | + |
| 146 | +--- |
| 147 | + |
| 148 | +## Install |
| 149 | + |
| 150 | +```bash |
| 151 | +# Homebrew |
| 152 | +brew install hapiio/tap/git-profile |
| 153 | + |
| 154 | +# Go |
| 155 | +go install github.com/hapiio/git-profile@latest |
| 156 | +``` |
| 157 | + |
| 158 | +Binaries for Linux and macOS (Apple Silicon + Intel) are on the [releases page](https://github.com/hapiio/git-profile/releases). |
| 159 | + |
| 160 | +Shell completions for bash, zsh, and fish are included. |
| 161 | + |

| 163 | + |
| 164 | +## Why I built it |
| 165 | + |
| 166 | +I switch between a full-time job, personal projects, and a few open-source repos every day. After the third time I pushed a commit with the wrong email to a client repo, I looked for a tool that handled all of it — SSH keys, GPG keys, auto-apply hooks — in one place. I didn't find one, so I built it. |
| 167 | + |
| 168 | +The entire tool is a single static binary with no runtime dependencies. Profiles are stored as plain JSON in `~/.config/git-profile/config.json` so they're easy to back up or commit to a dotfiles repo. |
