# GIT THEORY

* git status is modified to append an index before each filename

    cole@machine:~/PROJECTS/gtr-bf$ gs
    # On branch master
    # Untracked files:
    #   (use "git add <file>..." to include in what will be committed)
    #
    # 0 - TEST.MD
    # 1 - TEST2.md
    # 2 - TEST3.md
    nothing added to commit but untracked files present (use "git add" to track)

* git add modified to accept indices in place of filenames

    cole@machine:~/PROJECTS/gtr-bf$ ga 0 2
    cole@machine:~/PROJECTS/gtr-bf$ gs
    # On branch master
    # Changes to be committed:
    #   (use "git reset HEAD <file>..." to unstage)
    #
    # new file:   0 - TEST.MD
    # new file:   2 - TEST3.md
    #
    # Untracked files:
    #   (use "git add <file>..." to include in what will be committed)
    #
    # 1 - TEST2.md

* Most of the time we're adding one file or all of them. 
The indices become particularly useful when, for example, 
working on a feature that touches a lot of files 
or perhaps with refinery extensions which end up 
having extremely long path names. 

    cole@machine:~/PROJECTS/gtr-bf$ git reset 
    cole@machine:~/PROJECTS/gtr-bf$ gs
    # On branch master
    # Untracked files:
    #   (use "git add <file>..." to include in what will be committed)
    #
    # TEST.MD
    # TEST2.md
    # TEST3.md
    nothing added to commit but untracked files present (use "git add" to track)

* Say, for example, you are working on a complex nested form 
and so you put a debugging line in the rails controller that says something like 
"raise params.to_s". After working on your haml scss and coffee files, 
you go to commit and you want everything except the controller 
which you only changed for debugging purposes. You could git add -A 
and then git reset the controller, or you can do this:

    cole@machine:~/PROJECTS/gtr-bf$ ga -1
    cole@machine:~/PROJECTS/gtr-bf$ gs
    # On branch master
    # Changes to be committed:
    #   (use "git reset HEAD <file>..." to unstage)
    #
    # new file:   0 - TEST.MD
    # new file:   2 - TEST3.md
    #
    # Untracked files:
    #   (use "git add <file>..." to include in what will be committed)
    #
    # 1 - TEST2.md
