felt - Defines aliases and executes them.

felt is a simple command runner, written in Rust.

Install

Install Rust first. Then you can use cargo command to install felt.

cargo command is bundled with Rust.

cargo install felt

Supported OS

Usage

Put a .feltrc.toml file in your home directory, which means ~/.feltrc.toml file.

[felt]
root = true
node_modules = true

[command]
hello = "echo Hello! I\\'m Felt!"
nid = "npm install --save-dev"

You have defined hello command above. Let's execute it

felt hello

You will get output Hello! I'm Felt!.

You can also execute them with args.

felt nid esbuild react react-dom

Execute node_modules

felt can execute command in ./node_modules/.bin/ directly. If you want this feature, set node_modules in .feltrc.toml to true.

# You may have some Node.js binaries.
npm install esbuild

# This execute ./node_modules/.bin/esbuild
felt esbuild index.js --minify --oufile build/index.js

Notice: Currently, felt searches node_modules in just current execution directory. Even if other related directory has node_modules, felt cannot find it.

.feltrc.toml

.feltrc.toml is config file for felt. It may be put in home directory.

[felt]
# If root is true, felt doesn't see parent directory's .fetlrc.toml
# If this file is in home, you should set root to true.
# You can omit this line when it is false.
root = true

# If node_modules is true, felt can run binaries in ./node_modules/.bin/
# If false, disable the feature.
# If omit this line, its value is inherit from parent, or false when no parents set any value.
node_modules = true

[command]
# You can define yor command aliases!

# felt redis-up
redis-up = "docker run -it --rm -p 6379:6379 redis"

# felt countfiles
countfiles = "ls -l | wc -l"

List all your commands

felt --list

or

felt -l

Local .feltrc.toml

felt uses .feltrc.toml in below order.

1. current directory
2. parent directory
3. parent of parent...(recursively)

If current directory is out of home(e.g. /tmp/), append ~/.feltrc.toml to last of above list.

If felt found root = true file. felt stops traverse there.

For example, home .feltrc.toml is:

[felt]
root = true
node_modules = false

[command]
hello = "echo Hello"
hello2 = "echo Hi"

And ~/myproject/.feltrc.toml is:

[felt]
node_modules = true

[command]
hello = "echo Helloooooooooooooooo"

You can:

cd ~/myproject
felt hello
felt hello2
