2011/10/08 7 Who uses DocBlox? 

2011/10/08 8 Installation Installation via PEAR $ pear channel-discover pear.docblox-project.org $ pear channel-discover pear.michelf.com $ pear install docblox/DocBlox-beta Manual installation See http://docs.docblox-project.org/Installation.html#manual-installation Has become obsolete with DocBlox 0.15.1 

2011/10/08 9 Running docblox $ docblox -d [FOLDER] -f [FILE] -t [DESTINATION] $ docblox parse -d [FOLDER] -f [FILE] -t [STAGING] $ docblox transform -s [STAGING]/structure.xml -t [DESTINATION] OR 

2011/10/08 10 Running docblox: Incremental parsing $ docblox parse -d [FOLDER] -f [FILE] -t [STAGING] $ docblox transform -s [STAGING]/structure.xml -t [DESTINATION] ➔ Structure file is written to a staging location ➔ Every parsing run DocBlox will know if a file has changed ● If so, re-parse ● If not, re-use ➔ Advantages: ● Parsing speed is increased ● Structure file is not distributed along with rest of documentation 

2011/10/08 11 Running docblox: Options $ docblox –-help -h [--help] Show this help message -q [--quiet] Silences the output and logging -c [--config] [STRING] Configuration filename OR "none", when this option is omitted DocBlox tries to load the docblox.xml or docblox.dist.xml from the current working directory -f [--filename] STRING Comma-separated list of files to parse. The wildcards ? and * are supported -d [--directory] STRING Comma-separated list of directories to (recursively) parse. -t [--target] [STRING] Path where to store the generated output (optional, defaults to "output") -e [--extensions] [STRING] Optional comma-separated list of extensions to parse, defaults to php, php3 and phtml -i [--ignore] [STRING] Comma-separated list of file(s) and directories that will be ignored. Wildcards * and ? are supported -m [--markers] [STRING] Comma-separated list of markers/tags to filter, (optional, defaults to: "TODO,FIXME") -v [--verbose] Provides additional information during parsing, usually only needed for debugging purposes --title [STRING] Sets the title for this project; default is the DocBlox logo --template [STRING] Sets the template to use when generating the output --force Forces a full build of the documentation, does not increment existing documentation --validate Validates every processed file using PHP Lint, costs a lot of performance --parseprivate Whether to parse DocBlocks tagged with @internal --visibility [STRING] Specifies the parse visibility that should be displayed in the documentation (comma seperated e.g. "public,protected") --defaultpackagename [STRING] name to use for the default package. If not specified, uses "default" 

2011/10/08 12 Configuration ➔ Stored as XML ➔ docblox.dist.xml or docblox.xml DocBlox data/output data/output . tests/* 

2011/10/08 13 Writing Docblocks ➔ Docblocks are used to tag elements with meta-data ➔ Specific type of comment: /** … */ ➔ Three parts: ● Short description, one liner ● Long description, a complete description of the element ● Tags, annotations which provide additional information 

2011/10/08 14 Docblocks - II /** * This is a short description. * * This is a long description, which may span * multiple lines and contain {@inline} tags and * can be *styled* with `Markdown`. * * @param string $a This is the first variable. * @param \Exception $b This is the second variable. * @param array $c This is the third variable. * * @return void */ function myFunction($a, \Exception $b, array $c) { } 

2011/10/08 15 Supported elements ➔ Files ➔ Namespaces ➔ Includes & requires ➔ Classes ➔ Traits (not yet, is coming) ➔ Functions, methods and closures ➔ Properties ➔ Constants, global and class 

2011/10/08 16 Supported tags ➔ @abstract ➔ @access ➔ @api ➔ @author ➔ @category ➔ @copyright ➔ @deprecated ➔ @example ➔ @final ➔ @filesource ➔ @global ➔ @ignore ➔ @internal ➔ @license ➔ @link ➔ @method ➔ @name ➔ @package ➔ @param ➔ @property ➔ @return ➔ @see ➔ @since ➔ @static ➔ @staticvar ➔ @subpackage ➔ @throws / @throw ➔ @todo ➔ @tutorial ➔ @uses / @usedby ➔ @var ➔ @version 

2011/10/08 17 Inheritance ➔ Docblocks inherit by default (if not overridden) ● Short description ● Long description – Can be augmented using {@inheritdoc} ● Specific tags 

2011/10/08 18 Inheritance - Classes ➔ Methods ➔ Properties ➔ Tags ● @package ● @subpackage – if @package is the same as parent ● @version ● @copyright ● @author 

2011/10/08 19 Inheritance - METHODS ➔ Tags ● @param ● @return ● @throw / @throws ● @version ● @copyright ● @author 

2011/10/08 20 Inheritance - Properties ➔ Tags ● @var ● @version ● @copyright ● @author 

2011/10/08 21 Inheritance - Example class Parent { /** * Short description. * * @api * @param int $a First param. * @param string $b Second param. */ function doIt($a, $b) { .. } } class Child extends Parent { function doIt($a, $b) { .. } } DocBlox adds this for you. Note the missing @api tag /** * Short description. * * @param int $a First param. * @param string $b Second param. */ 

2011/10/08 22 Inheritance - @inheritdoc class Parent { /** * Short description. * * This is my long description. * * @param int $a First param. * @param string $b Second param. */ function doIt($a, $b) { .. } } class Child extends Parent { function doIt($a, $b) { .. } } /** * Short description. * * This method adds another bit of functionality * {@inheritdoc} * * @param int $a First param. * @param string $b Second param. */ 

2011/10/08 23 Inheritance - @inheritdoc class Parent { /** * Short description. * * This is my long description. * * @param int $a First param. * @param string $b Second param. */ function doIt($a, $b) { .. } } class Child extends Parent { function doIt($a, $b) { .. } } /** * Short description. * * This method adds another bit of functionality * This is my long description. * * @param int $a First param. * @param string $b Second param. */ DocBlox adds this for you. 

2011/10/08 24 References ➔ From Docblocks you can refer to other parts of the documentation using ● @uses ● @see ● @link and {@link .. } ● @example * @uses \My\Namespace\Class::function() * @see \My\Namespace\Class::$property * @link http://my.domain link text * @example gist:123456 

2011/10/08 25 Plugins ➔ Core functionality is captured in a plugin (eat your own dog food) ➔ Easy, pluggable event-based system ➔ Can manipulate many functions in DocBlox ➔ Add your own Transformation Writers 

2011/10/08 26 Plugins: invoking ➔ Add to configuration file as `plugins/plugin` element ➔ DocBlox Core plugin is assumed when nothing is defined ➔ Autoloading is set up by DocBlox ➔ Can have options, added in configuration file 

2011/10/08 27 Plugins: Configuration ... value ... 

2011/10/08 28 Plugins: Creating ➔ Skeleton can be generated using the following command: $ docblox plugin:generate -t [PATH] -n [NAME] 

2011/10/08 29 Plugins: Example class DocBlox_Plugin_Core_Listener extends DocBlox_Plugin_Abstract { /** * Apply a set of behaviours to the given structure. * * @docblox-event transformer.pre-transform * * @param sfEvent $data * * @return void */ public function applyBehaviours(sfEvent $data) { … } } 

2011/10/08 30 Plugins: Hooks ➔ No XSL hooks to start with ➔ Limited set to start with: ● system.log, default logger ● system.debug, logging of debug messages ● parser.log, logging of parser errors ● transformer.transform.pre, adding behaviour ● transformer.transform.post, post processing of output ● reflection.docblock-extraction.post, validating docblock ● reflection.docblock.tag.export, transform tag to specialized form 

2011/10/08 31 BONUS: Templates ➔ Templates are a sequence of data transformations ➔ Can contain other templates ➔ May reside anywhere; even in your own project ● which is recommended for custom templates ➔ A transformation invokes a Writer 

2011/10/08 32 BONUS: Templates ➔ Skeleton can be generated using the following command: $ docblox theme:generate -t [PATH] -n [NAME] 

2011/10/08 33 BONUS: THEMES ➔ Are a collection of `views` ➔ Can be transformed to a specific output ➔ Templates can cherry pick from different themes ➔ Themes can 'use' eachother 

2011/10/08 34 The (NEAR?) future ➔ Plugin and theme repository ➔ Tasks to package and upload themes and plugins ➔ Support for PHP 5.4 ➔ Improved tag support ➔ More output formats (DocBook, PDF, etc)
