sake - Sapphire Make

This document is currently a speculative discussion of how we would like the sake to behave. For information on the current sake tool, see the SilverStripe documentation wiki.

sake is a tool designed to a perform a number development tasks on Sapphire and SilverStripe CMS projects. It can help with the following:

  • Creating new Sapphire projects, making use of configuration templates
  • Managing modules in your project, using both git andsvn`
  • Executing post-deployment build scripts
  • Executing Sapphire maintenance scripts such as dev/build and dev/tests/all

Note that for the purposes of this discussion, a site made on SilverStripe CMS is just a special kind of Sapphire project.

Installing sake

sake is designed to be installed onto your machine by executing a bootstrap script:

curl http://www.example.org/somehwere/sake-bootstrap | sudo php

This is speculative, the installation doesn't work yet!

Creating projects

sake can create a skeletal Sapphire project in a directory on your site:

sake create ~/Sites/myproject

It can automatically put your project into a git or svn repository:

sake create ~/Sites/myproject --git
sake create ~/Sites/myproject --git=git@github.com:me/myproject.git 
sake create ~/Sites/myproject --svn=http://svn.example.com/myproject/trunk

It can also make use of "skeleton" definitions that give more information about how to set the site up. In particular, they say where to download ap

sake create ~/Sites/myproject --git --skeleton=cms_github_master --modules=cmsworkflow

Sake currently comes with a few predefined skeletons:

  • cms_stable: The latest stable release of SilverStripe CMS, with the blackcandy theme
  • cms_trunk: The development trunk of SilverStripe CMS, with the blackcandy theme
  • cms_github_master: The master branch of SilverStripe CMS from GitHub, with the blackcandy theme.

The skeleton will also specify the location of the module repository.

What does a skeleton contain?

Essentially, a skeleton contains a number of configuration values that override the defaults given in the configuration. The order of precedence for the configuration options is as follows:

  • Configuration from the command-line arguments
  • Configuration from the skeleton
  • Global configuration in ~/.sake

This means that you overload settings that the skeleton provides you. For instance, here we are replacing the default blackcandy theme with the artica theme.

sake create ~/Sites/myproject --git --skeleton=cms_github_master --modules=cmsworkflow --theme=artica

What configuration options are available?

In addition to --git, --svn, and --skeleton, the following configuration options are available. These are the options that can be overwritten by the skeletons.

  • --theme: Select a theme to use:
    • --theme=artica: Use the artica theme
    • --theme=basic->mytheme: Use the basic theme, renaming it to mytheme within the project. This is useful when you're wanting to create your own theme based on a starting point.
  • --theme-repos: The format of theme repositories is unclear.
  • --modules: Select modules to use.
    • --modules=cmsworkflow,ecommerce/stable: Install the stable releases of cmsworkflow and ecommerce modules.
    • --modules=cmsworkflow/trunk,ecommerce/0.5.2: Install the development trunk of cmsworkflow and version 0.5.2 of ecommerce.
  • --module-repos: The format of module repositories is unclear.
  • --database: Set a database name; defaults to SS_(sitedirectory)

Managing modules

sake can be used to add and remove modules from your site:

cd ~/Sites/myproject
sake modules/add ecommerce
sake modules/add cmsworkflow/stable
sake modules/remove forum

After each such command, the post-deployment build scripts will be executed.

Post-deployment build scripts

sake can be used to define build and deployment actions such as post-deploy.

sake post-deploy

What this will actually do is execute the .sake/post-deploy.cmd.php script. Here is an example of what that might contain:

<?php
// Update modules as necessary
svnModule('sapphire', 'http://svn.silverstripe.org/open/modules/sapphire/trunk');
svnModule('cms', 'http://svn.silverstripe.org/open/modules/cms/trunk');
svnModule('jsparty', 'http://svn.silverstripe.org/open/modules/jsparty/trunk');

// Update the database
sake('dev/build');

// Update the static cache
sake('dev/buildcache');

Sake will create an initial post-deploy script for you when creating a project. It is designed to be called after checking the site code out into a new location to get the site to an executable state. This can be hooked into a git post-update or post-receive hook. It is also called by the module manager.

Writing build scripts

Before executing, all of the following include files will be included. You can define any methods in these as you see fit:

  • File: $PROJECTROOT/.sake/*.inc
  • File: ~/.sake/*.inc

When you call sake my/action/name, it will then look for one of the following, in this order:

  • File: $PROJECTROOT/.sake/my_action_name.cmd.php
  • File: ~/.sake/my_action_name.cmd.php
  • Method: sake_my_action_name()

It will either include the file it finds, or execute the method.

These build scripts can make use of the following built-in methods:

  • svnModule($name, $url): Check out or update a module out from svn as appropriate.
  • gitModule($name, $url): Check out or update a module out from git as appropriate.
  • sake($sakeURL, $args = array()): Execute another sake command.
  • sapphire($sapphireURL, $args = array()): Execute a sapphire command. Ordinarily, this would do the same as sake(); however, if a sake action has been overwritten then this will go straight to the sapphrie URL. This can be handy, for example, if you create .sake/dev_build.cmd.php, containing the following:

    <?php
    sapphire('dev/build');
    // Do some actions here that have to be executed after dev/build
    

Executing maintenance commands

sake can be used to call any URL in your Sapphire application. Although this is of limited usefulness for your general URLs, there are a number of useful URLs starting with dev/. For example:

sake dev           # See a list of dev/ actions
sake dev/build     # Upgrade the database schema as necessary
sake dev/tests/all # Run all unit tests

Fun fact: The Director::is_cli() will return true if you are calling a URL from sake, and can be used to tailor the input to the CLI text-based interface.
