10. Brief history of PyroCMS
StyleDNA produces StyleCMS
We realise we need a CMS
Back in 2007 PyroCMS was first born as
StyleCMS, a basic CMS for small sites
StyleDNA fails and burns horribly
PyroCMS rises from the ashes

Not enough PHP 5?

32. Basic Principles

Library autoload
Call more than singletons:
$foo = new Something(‘bar’);
$bar = new Something(‘baz’);
Use some kick-ass PHP 5 syntax:
$foo = Settings::item(‘bar’);

39. Managing the Code

40. Managing the Code

41. Managing the Code
Master, Branches, Tags
Master
Same as Subversion trunk
Default “branch” of the repository
$ git clone git://github.com/pyrocms/pyrocms.git
Should always be ready to tag or download, keep it stable!

42. Managing the Code
Master, Branches, Tags
Branches
Keep code out of the way
v1.0-dev is relatively stable
v2.0-dev seriously fucked
Work on X feature independent of version Y
$ git checkout v1.0-dev

43. Managing the Code
Master, Branches, Tags
Tags
Tag each version
Marks a specific commit as a version
Automatic “Downloads” entry on GitHub
http://github.com/pyrocms/pyrocms/zipball/v0.9.9.7
http://github.com/pyrocms/pyrocms/zipball/{$variable.cms_version}

44. Managing the Code
Master, Branches, Tags
Forks
User owned copy of your repository
People do your work for you
Use it to trial new contributors
