[[Github Overview]]
−
Git is the name of a distributed version control system. It plays the role of the CVS or SVN control systems that WeBWorK has used in the past
  
−
but the details of how it works are somewhat different. For obtaining up-to-date copies of software there is not much difference between git
 
−
and previous VCS. Developers however should read closely since git has a different conceptualization of how version control should be handled.
  
−
The difference allows considerably more flexibility for collaborative development. Consolidation no longer depends on a single site or single
  
−
administrator. Updates are also more modular and therefore easier to check and repair or remove if they cause trouble.
  
−  
−  
−
Git has many capabilities and can be used in many different ways. This page outlines a subset of git commands and workflows that seems to work
  
−
well for WeBWorK.
  
−  
−  
−
'''Github.com''' is a site which facilitates the collaborative development of open source projects. These sites are open (read-only) to the world.
 
−
WeBWorK has a master site at https://www.github.com/openwebwork where accepted modifications are being consolidated. The following repositories are
 
−
available at that site.
  
−
* webwork2 -- the course management face of WeBWorK
  
−
* pg -- the macros that help render the PG questions
 
−
* NationalProblemLibrary -- collection of questions (not yet implemented -- for now Jason Grout's repository at:
 
−
* wwmoodle -- plugins that connect moodle and webwork
  
−
* ww_question_server -- another plugin project connecting moodle question types to the WeBWorK webservice
  
−
* admintools -- a collection of command line scripts used by larger sites serving WeBWorK

=== Workflow ===
  
−
On your local git repository the following workflow seems to minimize clashes with work being done elsewhere.
  
−
Commit early and often to your local branch.
 
−  
−  
−
clone the remote repo
  
−
git checkout -b my_new_feature (start a new branch to work on a single feature)
  
−
..work and commit some stuff
  
−
git pull origin master (pull changes from the upstream github repository into your master copy)
  
−
git rebase master (apply updates to your my_new_feature branch so that it looks like it branched from the updated master copy)
  
−
..work and commit some stuff
  
−
git pull origin master
 
−
git rebase master
  
−
..finish the feature
  
−
git checkout master
  
−
git merge my_new_feature (merge your changes back into your local master copy)
  
−
git push origin master (publish the changes in your master copy to your github account)
  
−
Issue pull request to openwebwork
  
−  
−
Individual developers for webwork also have their own sites (analogous to the branches in SVN, but more easily accessible)
  
−
* Michael Gage: https://www.github.com/mgage

* Jason Aubrey: https://www.github.com/aubreyja

=== Writing a good commit line ===
  
−  
−
When making commits I found this advice to be useful.
  
−
*Write a good first line, (like the subject line of an email) that describes what you did. This is the line that summarizes the commit so that when searching the
 
−
commit tree one can find where a feature was added.
 
−
* Good style: Start with a verb in the present tense. These read well in the commit tree. For example:
 
−  
−
Add slider bar to library browser.
  
−
Fix bug in level_curve_checker subroutine
  
−
* Follow the subject line with a blank line.
 
−
* Then add as much as you want to explain what changes were made and any other information you want preserved. (A diff of the changed files is preserved automatically.)
  
−  
−
* You can use git log to see how previous commits were worded. (Don't copy any of my first examples, but the later ones are getting better.)
