2. Problem
3. Dependent Libraries
4. Dependent Libraries
5. Dependent Libraries
6. Many Separate Projects
7. Overview of Tools  Python: easy_install, pip  Ruby: gems  Java: maven, ivy  C#(.NET): NuGet, NuPack  PHP: PEAR/Pyrus
8. PEAR. Why NOT?  #pyrus mypear = hack  Channel1/Package1 != Channel2/Package1  No “Source”, only “Dists”  Special Package Type (+/-)
9. Composer. Silver Bullet?
10. Composer. Simple  #wget http://getcomposer.org/composer.phar  #vi /path/to/project/.composer.json  #php composer.phar install  PEAR package on release?
11. Composer. File { "require": { "vendor/package1": "1.3.2", "vendor/package2": "1.*", "vendor/package3": ">=2.0.3" } }
12. Composer. Fundamentals  Package Repository = Metadata  Storage Separated from Repository  Unique Package Name = vendor/package  Different Storage Types (Downloaders)  “Source” & “Dist”  Dependecy Resolver
13. Composer. Repository File "composer\/composer":{ "name":"composer\/composer", "description":"Package Manager", "maintainers":[], "versions":{ "master-dev":{ "require":{ "php":">=5.3.0", "symfony\/console":"2.0.5", "symfony\/finder":"2.0.5" } } } }
14. Composer. Repository  PlatformRepository (php & extensions)  ComposerRepository ($url/composer.json)  PearRepository (PEAR channel support)  VcsRepository (github, git, svn, hg)  LocalRepository?
15. Composer. Downloader "source":{ "type":"git", "url":"http:\/\/github.com\/composer\/composer.git", "reference":"e6c3929ea9f7d732ed3352dc06ed950af140ebf7", "shasum":"" }, "dist":{ "type":"zip", "url":"<...>e6c3929ea9f7d732ed3352dc06ed950af140ebf7", "shasum":"e32a4bac17d56533393b856699491c4c02f3e1ab", "reference":"e6c3929ea9f7d732ed3352dc06ed950af140ebf7" }
16. Composer. Downloader  ZipDownloader (dist)  TarDownloader (dist: tar, tar.gz, tar.bz2)  PharDownloader (dist)  PearDownloader (dist: uses tar)  GitDownloader (source)  HgDownloader (source)
17. Composer. Installer  LibraryInstaller (vendor/*) "composer\/composer":{ "name":"composer\/composer", "description":"Package Manager", "type":"library" }
18. Composer. Dependency Resolver  OpenSUSE's Libzypp satsolver  Requires  Conflicts  Provides  Replaces  Recommends  Suggests
19. Composer. Dependency Resolver "require":{ "php":">=5.3.0", "symfony\/console":"2.0.5", "symfony\/finder":"2.0.5" }
20. Composer. Autoload  PSR-0 Autoloading (.composer/autoload.php) "versions":{ "master-dev":{ "autoload":{ "psr-0":{ "Composer":"src\/" } } } }
