# Minion
|
|
|
|
*NOTE: Minion is currently in a beta state, please report any issues in the issue tracker*
|
|
|
|
Minion is a module for running database migrations located in the Kohana cascading filesystem, but it also provides a useful framework for creating cli based tasks.
|
|
|
|
The original "need" behind Minion was the lack of a good db migrations system, capable of selecting migrations
|
|
from multiple locations (i.e. different modules).
|
|
|
|
The system is inspired by ruckusing, which had a nice system for defining tasks but lacked the desired flexibility.
|
|
|
|
## Requirements
|
|
|
|
* [kohana-database](https://github.com/kohana/database) is required by the migration tasks
|
|
|
|
## Compatibility
|
|
|
|
Minion should be compatible with both Kohana 3.0.x and 3.1.x
|
|
|
|
## Getting Started
|
|
|
|
First off, download and enable the module in your bootstrap
|
|
|
|
Then copy the binary `minion` into your webroot (i.e. the folder where index.php is, edit the binary if you want to store it in a different location)
|
|
|
|
You can then run minion like so:
|
|
|
|
./minion {task}
|
|
|
|
To view a list of minion tasks, run minion without any parameters, or with the `--help` option
|
|
|
|
./minon
|
|
./minion --help
|
|
|
|
To view help for a specific minion task run
|
|
|
|
./minion {task} --help
|
|
|
|
For security reasons Minion will only run from the cli. Attempting to access it over http will cause
|
|
a `Kohana_Exception` to be thrown.
|
|
|
|
If you're unable to use the binary file for whatever reason then simply replace `./minion {task}` in the above
|
|
examples with
|
|
|
|
php index.php --uri=minion --task={task}
|
|
|
|
## Writing your own tasks
|
|
|
|
All minion tasks must be located in `classes/minion/task/`. They can be in any module, thus allowing you to
|
|
ship custom minion tasks with your own module / product.
|
|
|
|
Each task must extend the abstract class `Minion_Task` and implement `Minion_Task::execute()`.
|
|
|
|
See `Minion_Task` for more details.
|
|
|
|
## Documentation
|
|
|
|
Code should be commented well enough not to need documentation, and minion can extract a class' doccomment to use
|
|
as documentation on the cli.
|
|
|
|
## Testing
|
|
|
|
This module is unittested using the [unittest module](http://github.com/kohana/unittest).
|
|
You can use the `minion` group to only run minion tests.
|
|
|
|
i.e.
|
|
|
|
phpunit --group minion
|
|
|
|
Feel free to contribute tests(!), they can be found in the `tests/minion` directory. :)

## FAQ
|
|
|
|
### Can't I just create my own controllers instead of creating "tasks"
|
|
|
|
Yes, controllers offer just as much control as tasks, however there are a number of advantages to tasks:
|
|
|
|
* They can only be run via command line or through code (see note about http)
|
|
* All the groundwork for interacting with the user on the command line is already in place, you
|
|
just need to take advantage of it
|
|
* It provides a uniform way to access and perform tasks on the command line, rather than creating an elaborate
|
|
collection of controllers while trying to restrict access to them. If you create a module that requires command
|
|
line interaction then you just ship a minion task with it and users will be able to start using it with minimal
|
|
setup & configuration
|
|
|
|
### Eeew why aren't you using ORM xyz?
|
|
|
|
In order to prevent conflicts across installations Minion aims to have as few dependencies as possible.
|
|
|
|
### This is awesome! How can I contribute?
|
|
|
|
Thanks for wanting to help out, just fork, commit, push, and send a pull request :)

Sorry you feel that way, it'd be useful if you could create an issue outlining what you think should be changed.
