koshu v0.6.2

Koshu (shell)

The honey flavoured task automation tool

Installation

Prerequisites

• bash 3.2 +

Local

Simply download koshu.sh to your project directory and execute koshu by typing ./koshu.sh.

Pre-release

curl https://raw.githubusercontent.com/kristofferahl/koshu-shell/master/src/koshu.sh > ./koshu.sh

Stable

curl https://raw.githubusercontent.com/kristofferahl/koshu-shell/0.5.4/src/koshu.sh > ./koshu.sh

To make running your "project local" koshu easier, you add an alias for koshu.sh to your shell.

alias koshu='./koshu.sh'

Global

You can install koshu globally using npm install koshu -g and execute it by typing koshu.

Setup

Run koshu init to create a "koshufile" in the current directory.

Koshufile

Tasks

Use the following syntax in your koshufile to define a task.

task setup {
  echo 'Setting up...'
}

You may also define a "default" task that is executed if no task name is passed to koshu.

task default {
  echo 'Running default task...'
}

Dependencies

You can define dependencies between your tasks by using the depends_on keyword followed by the name of the task you wish to depend upon.

task test {
  depends_on compile
}

In the example above, the compile task will be executed before any code placed after the depends_on statement is executed. A single task will never be executed more than once.

Executing tasks

./koshu.sh <taskname>

Parameters

Parameters you want set as variables can be passed to koshu by providing the -p or --param option followed by a name/value pair.

Default values can be set in your koshufile using the param function.

param foo='default value'

task default {
  echo "$foo"
}

Environment variables
