ganbatte (gnb)

한국어 | Command reference | Specification | Releases

Your shell history knows what you repeat. ganbatte turns it into aliases and workflows.

Your .zshrc knows your shortcuts. Your shell history knows your habits. Your project knows its workflows.

ganbatte puts them in one place: a local command hub for migrating aliases, mining repeated commands, and promoting command sequences into reusable workflows.

brew install bssm-oss/tap/ganbatte

gnb suggest   # find repeated commands and workflow candidates
gnb migrate   # import existing shell aliases
gnb           # browse everything in a TUI

Why It Exists

Shell aliases are fast until your .zshrc becomes an alias graveyard. Make, just, and task are great for project build tasks, but they are not designed for personal command shortcuts, cross-shell alias migration, or history-driven recommendations.

Atuin remembers what you typed. ganbatte turns what you repeat into commands you can keep.

gnb sits in the middle:

Need	Shell aliases	make/just/task	ganbatte
Personal shortcuts	Yes	No	Yes
Project onboarding workflows	Manual	Yes	Yes
Cross-shell config	No	Partial	Yes
Parameters without shell functions	No	Yes	Yes
Dangerous command confirmation	No	Manual	Yes
TUI discovery	No	Usually no	Yes
History-based suggestions	No	No	Yes

Killer Features

1. Suggest Shortcuts From Real Usage

gnb shell-init can passively append command history to ~/.local/share/ganbatte/track.log without spawning the gnb binary for every command. gnb suggest then uses shell history or the track log to recommend aliases, parameterized aliases, and workflows.

gnb suggest
gnb suggest --apply
gnb suggest --from-history

$ gnb suggest
Analyzing ganbatte track log (/Users/you/.local/share/ganbatte/track.log) (312 entries)...

=== Alias Suggestions ===
  1. c = claude
     Used 5 times · saves ~25 keystrokes

=== Parameterized Alias Suggestions ===
  1. gcl(repo) -> git clone {repo}
     Pattern 'git clone <...>' used 25 times with 25 variants

=== Workflow Suggestions ===
  1. git-add
     Step 1: git add .
     Step 2: git commit -m "update"
     Step 3: git push
     Sequence appeared 7 times

Applying all suggestions would save ~89 keystrokes based on your history.

Suggestions are ranked by estimated keystrokes saved, not just raw frequency. Destructive commands detected during --apply are marked with confirm = true.

2. Migrate Existing Shell Aliases

Bring your current .zshrc, .bashrc, .bash_aliases, or fish aliases into one managed config.

gnb migrate
gnb migrate --dry-run
gnb migrate --shell zsh

Example flow:

$ gnb migrate
Found 17 aliases in /Users/you/.zshrc
Found 8 aliases in /Users/you/.bash_aliases

25 new alias(es) to import:
  gs = "git status -sb"
  ll = "eza -alF --git"
  dc = "docker compose"

Import all? [Y/n] y

3. Browse Everything in a TUI

Run gnb with no arguments to open the command hub: fuzzy search, preview, tags, and global/project labels for every alias and workflow.

Privacy

gnb suggest analyzes local shell history files and the local ganbatte track log. Nothing is sent to a server, and ganbatte has no telemetry, account, cloud sync, or AI command generation.

Install

Homebrew

brew install bssm-oss/tap/ganbatte

Go

go install github.com/bssm-oss/ganbatte/cmd/gnb@latest

Release Archive

Download a platform archive from GitHub Releases, extract gnb, and place it on your PATH.

Quick Start

Start From Existing Aliases

gnb migrate
echo 'eval "$(gnb shell-init)"' >> ~/.zshrc
source ~/.zshrc

gs           # runs the migrated alias
dc up -d     # works like a native shell function

For bash, add the same eval line to ~/.bashrc. For fish:

gnb shell-init | source

Start From Scratch

gnb init
gnb add gs "git status -sb"
gnb run gs

Run gnb with no arguments to open the TUI browser.

Core Features

Global and Project Scopes

Global config lives in ~/.config/ganbatte/config.{toml,yaml,json}. Project config lives in .ganbatte.{toml,yaml,json} in the current directory or a trusted parent repository.

Project entries override global entries with the same name. gnb run asks for confirmation before executing a project item that shadows a global item.

gnb list --scope global
gnb list --scope project
gnb run setup --yes

Parameterized Aliases

[alias.gco]
cmd = "git checkout {branch}"
params = ["branch"]

[alias.glog]
cmd = "git log --oneline -{count}"
params = ["count"]
default_params = { count = "10" }

gco feature/login
glog
glog 30

Workflows

[workflow.deploy]
description = "Lint, test, build, and push"
params = ["branch"]
tags = ["deploy", "ci"]

[[workflow.deploy.steps]]
run = "pnpm lint"

[[workflow.deploy.steps]]
run = "pnpm test"
on_fail = "stop"

[[workflow.deploy.steps]]
run = "git push origin {branch}"
confirm = true

gnb run deploy main --dry-run
gnb run deploy main

Confirm Guardrails

Use confirm = true for commands that should never run accidentally.

[alias.clean-docker]
cmd = "docker system prune -af"
confirm = true

TUI Browser

gnb

The TUI gives you fuzzy search, preview, tag filtering, and global/project labels for aliases and workflows.

Multi-Format Config

TOML, YAML, and JSON are first-class and equivalent.

gnb init --format toml
gnb config convert --to yaml
gnb config path
