How to? Drupal developer toolkit

Drupal Camp Donetsk

Drupal developer toolkit

Two major areas to discuss:

Technical tools Organizational hints

80% is a 'should' not a 'must'

Technical tools

The platform: *AMP Developer sofware toolkit

LAMP / WAMP

OS Linux / Windows / Virtual Machine

LAMP / WAMP

Webserver Apache / nginx / Microsoft IIS

Any Apache version is fine (1.3, 2.0, 2.2) . Enable mod_rewrite .

LAMP / WAMP

Database MySQL / Postgres / SQLite

SQLite implementation is still weak; Postgres users may have problem with some

modules

Tune MySQL

Adjust default MySQL 5.x settings

innodb_buffer_pool_size = 256M innodb_flush_log_at_trx_commit=2 innodb_flush_method=O_DIRECT innodb_log_file_size = 128M innodb_log_buffer_size= 4M

LAMP / WAMP

Tune PHP

Tune PHP modules / settingsphp5-gd, php5-xdebug, php5-pdo,

php5-mysql(i), php5-xml

memory_limit 128M (check)

register_global off

max_execution_time 30

sendmail or module SMTP

Development tools: debugging

Use xdebug (default port: 9000) Use the 'watchdog' function watchdog( 'Apache Solr',

'Adding @count documents.',

array('@count' => count($documents))

);

'watchdog' function result

http://example/admin/reports/dblog

● Arrays, arrays, more arrays, nested arrays, ...

object(stdClass)[57]…public 'rdf_mapping' => array 'rdftype' => array 0 => string 'sioc:UserAccount' (length=16) 'name' => array 'predicates' => array … 'homepage' => array 'predicates' => array … 'type' => string 'rel' (length=3)

Use dpm() function from the module 'devel'

Need to run quick PHP snippet?

Such things are nice: http://ideone.com (no Drupal there)

However this is better:

http://example.local/devel/php

(by devel module, with Drupal stuff)

Environment tools

Version control system Integrated development environment Drupal ecosystem

We're at 50% of slides!

Version control system

Git / SVN / Mercurial

SVN – simple, centralized Git – complicated, native for Drupal,

powerful Mercurial – in between CVS – outdated! Other: Bazaar, MS TFS (former VSS)

Use IDE

IDE NetBeans / Eclipse / CodeLobster

Provides syntax highlighting, autocompletion, integration with debugging and VCS.

Environment tools

Install several browsers for different user roles

or use Masquerade module

Often you'll need to see the site by different groups of users – administrators, anonymous users, registered users, etc . Several browsers is more preferable – this have other usage as well.

Respect Drupal ecosystem

Drupal directory structure PHP/Drupal coding style Doxygen

Location of custom code / themes

Place all downloaded and handmade packages under

sites/all/modules/ , sites/all/themes/

Even better is to split sites/all/modules/contrib/ sites/all/modules/custom/

Drupal ecosystem

Follow the coding style.

Use correct variable_names, ClassNames,tab settings, comments. see

http://drupal.org/coding-standards

Respect Doxygen headers.

That is the reason why do we have nice documentation out-of-box at http://api.drupal.org .

/** * Fetches a user object based on * an external authentication source. * * @param string $authname * The external authentication username. * * @return * A fully-loaded user object if the user * is found or FALSE if not found. */function user_external_load($authname) {

BONUS TRACK: I NEED MORE!!

What's next?

Nice FF plugins like Poster https://addons.mozilla.org/en-US/firefox/addon/poster/

Firebug, extended integration http://drupal.org/project/drupalforfirebug

Drush – DRUpal Shell TRAC/RedMine PHP 5.2/PHP 5.3 on the same machine APC/xCache/eAccelerator Contribute! Make session
