26/10/2011 version 0.9.7.1 hotfix

25/10/2011 version 0.9.7

MAJOR NEW FEATURES:
- upgraded ls command to have a more intuitive interface
- added automatic indentation (thanks YorickPeterse!)
- added Pry::Method wrapper class to encapsulate method-related functionality

complete CHANGELOG:
* fixed syntax highlighting for object literals
* fixed ActiveSupport method-naming conflict with "in?"
* added --super option to edit-method, show-method, and friends -  making it easier to operate on superclass methods
* officially added edit --in to open previous expressions in an editor

27/9/2011 version 0.9.6.2 HOTFIX release
* downgrading to CodeRay 0.9.8 due to problems with 1.0 and rails (autoloading problem) see #280 on pry and #6 on CodeRay
* also added (as a minor feature) cirwin's implementation of edit --in
* added early break/exit for objectpath errors (the 'cd 34/@hello/bad_path/23')

19/9/2011 version 0.9.6
* restored previous behavior of command-line switches (allowing "-rfilename")
* removed -p option (--play) from edit command
* `edit` with no arguments now edits the current or most recent expression
* `edit` auto-reloads .rb files (need to specify -n to suppress)
* added -p option (--patch) to edit-method command, which allows
    monkeypatching methods without touching the original file
* edit-method can now edit REPL-defined methods
* cat --ex now works on exceptions in REPL-defined code
* play -m now uses eval_string.replace()
* play -m --open uses show-input to show play'd code
* added "unindent" helper to make adding help to commands easier
* local ./.pryrc now loaded after ~/.pryrc if it exists
* cat --ex N and edit --ex N now can navigate through backtrace, where cat --ex (with no args) moves throuh successive levels of the backtrace automatically with state stored on the exceptino object itself
* new option Pry.config.exception_window_size determines window size for cat --ex
* input_stack now implemented - pushing objects onto a pry instance's input_stack causes the instance to read from those objects in turn as it encounters EOF on the previous object. On finishing the input_stack the input object for the pry instance is set back to Pry.config.input, if this fails, pry breaks out of the REPL (throw(:breakout)) with an error message
* Pry.config.system() defines how pry runs system commands
* now injecting target_self method into command scope
* play now performs 'show-input' always unless eval_string contains a valid expression (i.e it's about to be eval'd)
* play and hist --replay now push the current input object onto the input_stack before redirecting input to a StringIO (works much better with pry-remote now)

8/9/2011 version 0.9.5

MAJOR NEW FEATURES:
- JRuby support, including show-method/edit-method and editor integration on both 1.8 and 1.9 versions
- extended cd syntax: cd ../@x/y
- play command now works much better with _in_ array (this is a very powerful feature, esp with Pry::NAV_PROMPT)
- history saving/loading is now lightning fast
- 'edit' (entered by itself) now opens current lines in input buffer in an editor, and evals on exit
- 'edit' command is also, in general more intelligent
- ls output no longer in array format, and colors can be configured, e.g: Pry.config.ls.ivar_color = :bright_blue
- new switch-to command for moving around the binding stack without exiting out of sessions
- more sophisticated prompts, Pry::NAV_PROMPT to ease deep spelunking of code
- major bug fix for windows systems
- much better support for huge objects, should no longer hang pry (see #245)
- cat --ex and edit --ex now work better

complete CHANGELOG:
* tempfile should end in .rb (for edit -t)
* ls output should not be in array format
* fix history saving (should not save all of Readline::HISTORY, but only what changed)
* prevent blank lines going to Readline::HISTORY (thanks cirwin!)
* ensure that cat --ex emulates the `whereami` format - includes line numbers and formatted the same, etc
* fixed bug #200 ( https://github.com/pry/pry/issues/200 )- string interpolation bug (thanks to ryanf)
* show-doc and stat now display method visibility (update WIKI)
* got rid of warnings caused by stricter ruby 1.9.3 rules
* remove interpolation of command names and fix interpolation error messag (update WIKI) (thanks ryanf!)
* 'nested sessions' now use binding stacks (so each instance manages its own collection of bindings without spawning other instances)
* 'cd ..' just pops a binding off the binding_stack with special behaviour when only one binding in stack - it breaks out of the repl loop
* added switch-to command (like jump-to but doesnt unwind the stack)
* show-method and show-doc now accept multiple method names
* control_d hook added (Pry.config.control_d_handler)
* behaviour of ^d is now to break out of current expr if in multi-line expr, or break out of current context if nested, or break out of pry repl loop if at top-level
* can no longer interpolate command name itself e.g #{x}-#{y} where x = "show" and y = "doc"
* ^C no longer captured
* got rid of Pry.active_instance, Pry.last_exception and friends.
* also special locals now shared among bindings in a pry instance (i.e _ex_ (and friends) re-injected into new binding entered with 'cd')
* renamed inp and out to _in_ and _out_ (to avoid collisions with actual locals in debugging scope)
* added third parameter to prompts, the pry instance itself (_pry) see https://github.com/pry/pry/issues/233 for why it's important
* cd behaviour when no args performs the same as `cd /`
* commands with keep_retval can now return nil (to suppress output now return 'void' instead)
* Pry::CommandProcessor::Result introduced
* Pry.view_clip() modified to be more robust and properly display Class#name
* edit command when invoked with no args now works like edit -t
* when edit is invoked (with no args or with -t) inside a multi-line expression input buffer, it dumps that buffer into a temp file and takes you to it
* got rid of Pry#null_input? since all that was needed was eval_string.empty?
* cd command now supports complex syntax: cd ../@y/y/../z
* JRuby is no longer a 2nd class citizen, almost full JRuby support, passing 100% tests
* added Pry::NAV_PROMPT (great new navigation prompt, per robgleeson) and Pry::SIMPLE_PRINT for simple (IRB-style) print output (just using inspect)
* _pry_ now passed as 3rd parameter to :before_session hook
* ls colors now configurable via Pry.config.ls.local_var_color = :bright_red etc
* ls separator configurable via, e.g Pry.config.ls.separator = "  "
* Pry.view_clip() now only calls inspect on a few immediates, otherwise uses the #<> syntax, which has been truncated further to exclude teh mem address, again related to #245

27/7/2011 version 0.9.3
* cat --ex (cats 5 lines above and below line in file where exception was raised)
* edit --ex (edits line in file where exception was raised)
* edit -t (opens a temporary file and evals it in current context when closed)
* `pry -r` requires now happen after plugin loading (so as not to interfere with
* new Pry.config.disable_auto_reload option, for turning off auto reloading by edit-method and related (thanks ryanf)
* add better error messages for `cd` command
* fixed exotic object regression - BasicObject.new etc now return "=> unknown"
* added reload-method command (reloads the associated file of a method)
* converted: import => import-set, version => pry-version, install => install-command
* Pry.config.command_prefix support (thanks ryanf!)
* fixed indentation for simple-prompt
* hist command now excludes last line of input (the command invocation itself)
* hist now has `history` alias
* missing plugins no longer raise exception, just print a warning to $stderr
* fixed jedit editor support

21/6/2011 version 0.9.2

* `command` method from CommandBase now accepts a :keep_retval arg that determines if command value is returned to pry session or just `nil` (`nil` was old behaviour)
