pry-git

A Ruby-aware git layer

Retrieve blame, perform diffs, make commits using the natural units of Ruby code.

pry-git enables you to diff an individual method , it can show you the blame for a method and ultimately allow you to commit 'methods' (rather than amorphous 'hunks' of code).

pry-git is a plugin for the pry REPL.

pry-git is very much proof of concept right now, stay tuned!

• Install the gem: gem install pry-git
• See the source code

Example: blame

pry(main)> git blame Pry#repl
John Mair   def repl(target=TOPLEVEL_BINDING)
John Mair     target = Pry.binding_for(target)
John Mair     target_self = target.eval('self')
John Mair
John Mair     repl_prologue(target)
Mon ouïe
John Mair     # cannot rely on nesting.level as
John Mair     # nesting.level changes with new sessions
John Mair     nesting_level = nesting.size
John Mair
John Mair     break_data = catch(:breakout) do
John Mair       nesting.push [nesting.size, target_self, self]
John Mair       loop do
John Mair         rep(target)
John Mair       end
John Mair     end
John Mair
John Mair     return_value = repl_epilogue(target, nesting_level, break_data)
Lee Jarvis    return_value || target_self
John Mair   end

Example: diff

pry(main)> git diff Pry#repl
   def repl(target=TOPLEVEL_BINDING)
+
+    # hey baby
     target = Pry.binding_for(target)
     target_self = target.eval('self')

+    # bink
     repl_prologue(target)

     # cannot rely on nesting.level as
     # nesting.level changes with new sessions
     nesting_level = nesting.size

     break_data = catch(:breakout) do
       nesting.push [nesting.size, target_self, self]
       loop do
         rep(target)
       end
     end

     return_value = repl_epilogue(target, nesting_level, break_data)
     return_value || target_self
   end

Example: add

Note that .git invokes the system git command (a . prefix forwards the line to the shell, see: shell commands)

pry(main) git add Pry#repl
pry(main) .git diff --cached
diff --git a/lib/pry/pry_instance.rb b/lib/pry/pry_instance.rb
index 7a4c403..6483a4a 100644

Features and limitations

• Just a proof of concept at this stage.
• The methods you're invoking the git commands on must be part of a git repo (of course).
• Commands currently just work with respect to HEAD; this restriction will be lifted in a later version.
• BETA software, beware!
