Neph

A modern command line job processor written in Crystal that can execute jobs concurrently. :rocket:

Used

Neph is used in which_is_the_fastest. In which_is_the_fastest, building time is reduced from 102[sec] to 33[sec]. neph.yml is here.

Installation

Cloning this project

git clone https://github.com/tbrand/neph

Compile

cd neph; shards build

Now executable binary is at neph/bin/neph.

Usage

Put neph.yml at root of your project

main:
  command:
    echo "Hello Neph!"

Execute neph

> neph

Options

You can specify job name by -j. In neph.yml,

hello:
  command:
    echo "Hello!"

Then,

> neph -j hello

To see other usages, use --help option

> neph --help

neph.yml

You can define dependencies between jobs like this

main:
  command:
    echo "Main!"
  depends_on:
    - hello
hello:
  command:
    echo "Hello!"

Here main job depends on hello. So when you execute neph, hello job is triggered before the execution of the main job.
See sample for details.
