Article contents:[[toc:]] == How to obtain the source code of eggs There are multiple ways to obtain the source of eggs. This document shows the most common possibilities. === Individual eggs ==== Using chicken-install {{chicken-install}} provides the {{-retrieve}} (short: {{-r}}) option to retrieve the source code of eggs given as argument. Use the {{-test}} option to obtain the source code of the test suite of eggs too, if available. Example: $ chicken-install -r -test spiffy The same invocation works for {{chicken-install}} from both CHICKEN 4 and CHICKEN 5. ==== Using any HTTP client Eggs are also available as tarballs that can be downloaded with any HTTP[S] client from [[https://code.call-cc.org/egg-tarballs/|code.call-cc.org/egg-tarballs/]]. Egg tarballs are generated by [[/egg/egg-tarballs|egg-tarballs]]. ==== Fetching the original egg source If you want to get the source code of an egg from its original source repository, you can find most of them here: * [[https://www.upyum.com/eggs-repo/egg-repositories.4.html|CHICKEN 4 Eggs Repositories]] * [[https://www.upyum.com/eggs-repo/egg-repositories.5.html|CHICKEN 5 Eggs Repositories]] === All eggs ==== Using git The source code of all available eggs is available via git. At the moment we provide four git repositories which contain source code of eggs: ; eggs-5-latest : only the latest version of all eggs for CHICKEN 5 ; eggs-5-all : all versions of all eggs for CHICKEN 5 ; eggs-4-latest : only the latest version of all eggs for CHICKEN 4 ; eggs-4-all : all versions of all eggs for CHICKEN 4 To clone these repositories, use your favorite git client and {{git://code.call-cc.org/<repo>}} as URL. {{<repo>}} is one of the repositories listed above. Example: $ git clone git://code.call-cc.org/eggs-5-latest Note that the history of those git repositories does '''not''' reflect the development history of eggs. They are just a representation of the cache of the egg servers as git repositories. You can see the history of releases, but not the history of development. ==== Using henrietta-cache [[/egg/henrietta-cache|henrietta-cache]] is the software used to build up egg caches in the egg servers. {{henrietta-cache}} periodically scans the source repositories of all eggs and incrementally updates the caches in egg servers. It uses as input the index of eggs for a given CHICKEN major version. The egg indexes, called ''egg-locations'' files, are available in the CHICKEN central Subversion server. You can otain a copy of the egg-location files here: * [[https://anonymous@code.call-cc.org/svn/chicken-eggs/release/5/egg-locations|For CHICKEN 5]] * [[https://anonymous@code.call-cc.org/svn/chicken-eggs/release/4/egg-locations|For CHICKEN 4]] To use {{henrietta-cache}} to fetch eggs you can run it like: $ henrietta-cache -r 5 -c chicken-5-eggs -e egg-locations Where {{5}} is the CHICKEN major release, {{chicken-5-eggs}} is the directory where the source code of eggs is going to be downloaded to and {{egg-locations}} is the ''egg-locations'' file. Note that for some eggs, those available via HTTPS, you might need to install the [[/egg/openssl|openssl]] egg additionally to {{henrieta-cache}}, as it is an optional dependency. You also need some external programs to extract the archives obtained by {{henrietta-cache}}. See its documentation for more information. Description of your changes:
