Overview

Show all Sake tasks (but no local Rake tasks), optionally only those matching a pattern.

$ sake -T
$ sake -T db

Show tasks in a Rakefile, optionally only those matching a pattern.

$ sake -T file.rake
$ sake -T file.rake db

Install tasks from a Rakefile, optionally specifying specific tasks.

$ sake -i Rakefile
$ sake -i Rakefile db:remigrate
$ sake -i Rakefile db:remigrate routes

Examine the source of a Rake task.

$ sake -e routes

You can also examine the source of a task not yet installed. 

$ sake -e Rakefile db:remigrate

Uninstall an installed task.

$ sake -u db:remigrate

Stores the source of a task into a pastie (pastie.caboo.se). Returns the url of the pastie to stdout.

$ sake -P routes

Can be passed one or more tasks.

Invoke a Sake task.

$ sake <taskname>

Some Sake tasks may depend on tasks which exist only locally.

For instance, you may have a db:version sake task which depends on the ‘environment’ Rake task. The ‘environment’ Rake task is one defined by Rails to load its environment. This db:version task will work when your current directory is within a Rails app because Sake knows how to find Rake tasks. This task will not work, however, in any other directory (unless a task named ‘environment’ indeed exists).

Sake can also serve its tasks over a network by launching a Mongrel handler. Pass the -S switch to start Sake in server mode.

$ sake -S

You can, of course, specify a port.

$ sake -S -p 1111

You can also daemonize your server for long term serving fun.

$ sake -S -d

Constructor Details

#initialize(args) ⇒ Sake

The ‘application’ class, this is basically the controller which decides what to do then executes.

end

Instance Method Details

#run ⇒ Object

This method figures out what to do and does it. Basically a big switch. Note the seemingly random return statements: return if you don’t want run_rake invoked. Some actions do want it invoked, however, so they don’t return (like version, which prints a Sake version then trusts Rake to do likewise).
