Flamework is the semi-fictional framework that powers Flickr.com. It's less of an actual framework and more of a design philosophy. None of the code in this project is actually taken from Flickr, but is rather a reconstruction of the way we built things there and the way we continue to build things now.
This library is a work in progress. While it basically works, it's lacking lots of the bits it really needs. As we pull these parts from other projects (and I've built most parts 10 times over by now), it'll start to take better shape. If you have stuff you want to add, fork, commit and file a pull-request.
Installation - As a base for a new project
- Copy everything to a web server running Apache with
AllowOverrides allfor the root.
- Ensure that the
templates_cdirectory can be written to by your webserver.
That might be it.
Installation - As an external library
Another way to use flamework is to clone it into a subfolder and build your project underneath it. This has the added advantage that you can just pull down updates as they happen, without having to rebase/merge your project on top of it. The library isn't set up to easily do this, automagically yet. Once it is, you will be able to point to your own config files, libraries, templates, etc. while still using all of the flamework guts.
In the meantime here's one way to use flamework in a separate project. It's not actually that complicated, just a bit boring. (Aaron promises to write a shell script to automate as much of this as possible Real Soon Now (tm).)
To start, imagine you've got two folders:
The copy of exflickr/flamework you've cloned from GitHub. For example:
The project you're working on. For example:
Your project might contain the following sub-folders, depending on how you set things up:
In this example, we'll assume that they are. The first sub-folder is your application's directory root (e.g. the thing the interweb sees). The second is where you store your application's shared libraries.
The first thing you should do is copy the default
.htaccess files for
the same folders (application root and shared libraries) from flamework:
cp /var/flamework/.htaccess /var/your-project/www/ cp /var/flamework/include/.htaccess /var/your-project/www/include/
(Don't forget that you'll still need to set up your templates and templates cache
directories for Smarty. You may want to copy over the
templates_c from the flamework trunk but those details are still left
up to you, for the time being.)
/var/your-project/www/.htaccess to include a php
config. Basically, all you're doing is telling PHP to look for libraries and other shared
code in your application first and then to fall back on flamework. For example:
php_value include_path "/var/your-project/www/include:/var/flamework/include:."
.htaccessfile you've copied over from flamework shouldn't need to be changed. The default configuration prevents anyone from reading its contents.
Now copy the default flamework config file in to your application's include directory:
cp /var/flamework/include/config.php /var/your-project/www/include/
Update the (newer) file accordingly with your application's configuration and be sure to add the following line. This does what it sounds like:
$GLOBALS['cfg']['flamework_skip_init_config'] = 1;
You're almost done. No, really. You just need to create an init.php file for your application. For example:
Here's the minimum amount of stuff you'll need to add in order for your application to use flamework:
define('URPROJECT_FLAMEWORK_DIR', '/var/flamework'); define('URPROJECT_ROOT_DIR', dirname(dirname(__FILE__))); include(URPROJECT_FLAMEWORK_DIR . '/include/config.php'); include(URPROJECT_ROOT_DIR . "/include/config.php"); include_once(URPROJECT_FLAMEWORK_DIR . '/include/init.php');
Here's what going on:
You are defining constants to indicate where your application and flamework are located.
Loading first the flamework
config.phpfile followed by your application's
config.php. Remember, the order that these files are loaded is important. You want to first load the default flamework configs (many of which you won't need to change or worry about) but then overwrites you ones you do care about, not the other way around.
Finally loading flamework's
Depending on your how your application is set up this may be all you need to do in order to use flamework. Once you've finished you can start using it all in your code, like this:
<?php include("include/init.php"); # your code goes here ?>
The coding style is idiosyncratic and will stay that way. There are no spaces between closing parentheses and opening braces. We indent with tabs. All functions in a library must start with the library name, globals too. We don't (often) use constants. An underscore at the start of a function means it's library-private, same with globals. Function names are all lowercase, split with underscores. We don't use objects.
We turn on E_ALL & E_STRICT, but ignore most E_NOTICEs because they're dumb. We do quote all hash keys, but we don't care about undefined keys or variables - isset() is vary rarely used.
If you submit patches that don't conform to the weird standards, they'll get reformatted. It's not you, it's me.
