runit-dev 0.1.1

Define and run named commands per project with runit.yaml

runit

Stop typing the same long commands over and over. runit lets you save commands with short names and run them instantly.

runit add build "cargo build --release"
runit build

That's it. No config files to manage, no setup step. Just add a command and run it.

Install

pip install runit-dev

Requires Python 3.10+. Works on macOS, Linux, and Windows.

Quick start

# Save a command
runit add test "pytest -v --tb=short"

# Run it
runit test

# See what you've got
runit list

Multiple steps

Commands can be a sequence. They run in order, stopping if any step fails.

runit add deploy "npm run build" "npm test" "rsync -av dist/ server:/var/www/"

runit deploy
# $ npm run build
# $ npm test
# $ rsync -av dist/ server:/var/www/

Parameters

Some commands are almost the same every time, just with a different value here and there. Use {var} placeholders and pass values positionally - just type the values after the command name, in order.

runit add deploy "kubectl apply -f k8s/{env}.yaml" "echo 'deployed to {env}'"

runit deploy staging
# $ kubectl apply -f k8s/staging.yaml
# $ echo 'deployed to staging'

runit deploy prod
# $ kubectl apply -f k8s/prod.yaml
# $ echo 'deployed to prod'

Multiple parameters just go in order:

runit add ssh "ssh {user}@{host}"

runit ssh admin 192.168.1.10
# $ ssh admin@192.168.1.10

You can set defaults with {var:default} - if you don't pass it, the default kicks in.

runit add push "docker push myapp:{tag:latest}"

runit push              # uses tag=latest
runit push v2.0         # uses tag=v2.0

Strings with spaces work fine in quotes:

runit add greet "echo {message}"

runit greet "hello world"
# $ echo hello world

If you forget a required parameter, runit tells you what's missing:

$ runit deploy
Missing: env
Usage: runit deploy <env>

Capture output as variables

Sometimes a later step needs the output of an earlier one. Prefix a step with @varname to capture its stdout into a variable, then use {varname} in any step that follows.

runit add whoami "@user whoami" "echo Hello, {user}"

runit whoami
# $ @user whoami
#   user = itayfliess
# $ echo Hello, itayfliess
# Hello, itayfliess

A more practical example — grab your local IP and use it:

runit add myip "@ip ifconfig en0 | grep 'inet ' | awk '{print \$2}'" "echo {ip}"

runit myip
# $ @ip ifconfig en0 | grep 'inet ' | awk '{print $2}'
#   ip = 192.168.1.5
# $ echo 192.168.1.5
# 192.168.1.5

Captures can be combined with regular parameters:

runit add deploy "@host cat config/{env}.txt" "scp build.tar {host}:/app/"

runit deploy staging

If a capture step fails, execution stops — same as any other step.

Random mode

Pick a random command from a list each time you run it.

runit add tip "echo 'commit often'" "echo 'write tests'" "echo 'take a break'" --mode random

runit tip
# $ echo 'take a break'   (random pick)

Built-in commands

runit ships with a set of built-in git/dev commands ready to use out of the box. They show up under "Built-in" in runit list and work in any project.

Command	Description
runit prune	Delete local branches whose remote has been deleted
runit untrack <path>	Remove a file from git tracking (without touching .gitignore)
runit loc [ext]	Count lines of code by file type (default: .py)
runit heatmap	Show the 20 most frequently changed files in git history

runit prune
# Fetches remote and deletes any local branches marked as gone

runit untrack src/secret.txt
# $ git rm --cached -r src/secret.txt

runit loc
# Counts all .py files

runit loc ts
# Counts all .ts files

runit heatmap
#  11 runit/cli.py
#   4 runit/runner.py
#   ...

Built-in commands can't be removed or edited, but you can override any of them by adding a project or global command with the same name.

Global commands

By default, commands are scoped to your project. If you want a command available everywhere, add it with -g:

runit add -g gs "git status -sb"
runit add -g gp "git push"

# Now 'runit gs' works in any directory

Project commands take priority - if you have a global build and a project build, the project one wins.

runit list           # shows both global and project commands
runit list -g        # shows only global commands

Inspecting commands

Use show to see the full details of a command - where it's stored, its mode, parameters, and every step.

runit show deploy
# deploy
#   source:  project (.git/runit.yaml)
#   mode:    sequential
#   params:  env (required), tag (default: latest)
#   steps:
#     1. kubectl apply -f k8s/{env}.yaml
#     2. echo 'tag: {tag:latest}'

runit show myip
# myip
#   source:  project (.git/runit.yaml)
#   mode:    sequential
#   captures: ip
#   steps:
#     1. @ip ifconfig en0 | grep 'inet ' | awk '{print $2}'
#     2. echo {ip}

Editing commands

Update a command without having to remove and re-add it.

# Replace the steps
runit edit deploy "new-step-1" "new-step-2"

# Change just the mode
runit edit deploy --mode random

# Update both steps and mode
runit edit deploy "new-cmd" --mode sequential

# Edit a global command
runit edit -g gs "git status -sb --porcelain"

Renaming commands

runit rename test t          # rename project command
runit rename -g gs gst       # rename global command

Removing commands

runit remove test           # remove project command
runit remove -g gs          # remove global command

Resetting

Clear all commands at once.

runit reset          # clear project commands
runit reset -g       # clear global commands
runit reset -a       # clear both project and global

Where are commands stored?

You don't need to think about this, but if you're curious:

• Git projects - inside .git/runit.yaml (invisible, not tracked)
• Other directories - in ~/.cache/runit/, keyed by folder
• Global commands - in ~/.config/runit/runit.yaml

No files in your project directory. Nothing to .gitignore.

All commands

Command	Description
runit <name> [args]	Run a saved command
runit add <name> "cmd" ...	Save a new command
runit edit <name> "cmd" ...	Update an existing command
runit show <name>	Show full command details
runit rename <old> <new>	Rename a command
runit remove <name>	Remove a command
runit reset	Clear all commands
runit list	List all commands (built-in, global, project)

Add -g to add, edit, rename, remove, list, or reset to target global commands.

Step syntax

Syntax	Meaning
{var}	Required parameter — pass positionally when running
{var:default}	Optional parameter with a default value
@varname cmd	Capture step — runs cmd, stores stdout as varname
