# CHANGELOG

## Master (Unreleased)

## 9.0.6 - 2016-09-29

### Fixed

* Error when using `byebug` with a ruby compiled against libedit (#241).
* Allow `Byebug.start_server` to yield the block passed to it when the actual
  port is already known (#277, thanks @cben).
* Use a standard license name so it can be more reliably used by tools (#275).

## 9.0.5 - 2016-05-28

### Fixed

* Error loading rc file when `ENV['HOME']` is unset.

## 9.0.4 - 2016-05-19

### Fixed

* Errors in rc file not being displayed to the user.

## 9.0.3 - 2016-05-16

### Fixed

* Unfriendly output in byebug's executable when no script specified (#256).
* Unfriendly output in byebug's executable when script doesn't exist.
* Unfriendly output in byebug's executable when script has invalid code.

## 9.0.2 - 2016-05-15

### Fixed

* Skip to get a line in eval context (#263, thanks @k0kubun).
* Debugger getting disabled after `continue` even when linetrace is enabled
  (#264, thanks @k0kubun).

## 9.0.1 - 2016-05-14

### Fixed

* `quit` never exiting when remote debugging (#201).

## 9.0.0 - 2016-05-11

### Fixed

* `irb` command unintentionally changing $PROGRAM_NAME.
* `pry` command failing.
* Unrelated error message when using `pry` command and Pry not installed.
* Interrupting program execution from remote control interface (#239, thanks
  @izaera).

### Removed

* Official Ruby 2.0.0 support. `var local` no longer works in Ruby 2.0. The
  rest of the commands should still work as before, but `byebug` is no longer
  tested against this version so they might start breaking in the
  future.

## 8.2.5 - 2016-04-27

### Fixed

* Allows paths with spaces (#244, thanks @HookyQR).
* Allows paths with colons (#244, thanks @HookyQR).

## 8.2.4 - 2016-04-08

### Fixed

* Reverts #211 which leads to an unusable debugger.

## 8.2.3 - 2016-04-07

### Fixed

* Better interaction with utilities like RSpec when hitting Ctrl-C.
* `irb` command when original program modified ARGV (#197, thanks @josephks).
* Unusable debugger when stdin redirected (#211,thanks @sethk).
* RC file loading when no explicit flag included (#223).
* Installation on some Windows systems (#175, #226).

## 8.2.2 - 2016-02-01

### Fixed

* Bug in rc file loading where most initialization commands would not be run.

## 8.2.1 - 2015-11-26

### Fixed

* Bug in evaluations using "eval".

## 8.2.0 - 2015-11-12

### Fixed

* [#184](https://github.com/deivid-rodriguez/byebug/issues/184) &
  [#188](https://github.com/deivid-rodriguez/byebug/issues/188), both due
  to the way of running evaluations in a separate thread.

### Added

* `debug` command to evaluate things in a separate thread, since this behavior
  was removed from default `eval` to fix the above issues.

## 8.1.0 - 2015-11-09

### Fixed

* Command history should be specific per project.
* Better error message in certain edge cases when printing the backtrace.
* Bug in evaluator which would show information about having stopped at a
  breakpoint in some cases.

### Added

* Ability to autolist source code after `frame` command.
* Ability to stop at lines where methods return.

## 8.0.1 - 2015-11-07

### Fixed

* Error stream wouldn't be properly reset when using standalone `byebug`.
* Confusing error message for invalid breakpoint locations.

## 8.0.0 - 2015-11-05

### Fixed

* [#183](https://github.com/deivid-rodriguez/byebug/issues/183). Compilation
  in Ruby 2.0. Regression introduced in 7.0.0
* "Return value is: nil" would be displayed when stopping right before the end
  of a class definition. We want to avoid showing anything instead.

### Changed

* Plugins now need to implement an `at_end` method (separate from `at_return`)
  in their custom processors.

## 7.0.0 - 2015-11-04

### Fixed

* [#177](https://github.com/deivid-rodriguez/byebug/issues/177). Some issues
  with formatting results of evaluations.
* [#144](https://github.com/deivid-rodriguez/byebug/issues/144). Ruby process
  after using byebug does no longer get slow.
* [#121](https://github.com/deivid-rodriguez/byebug/issues/121). `byebug`
  commands inside code evaluated from debugger's prompt are now properly working.
* Another evaluation bug in autocommands.
* `finish 0` command would sometimes fail to stop right before exiting the
  current frame.
* Runner's `--[no-]stop` option now works (thanks @windwiny).
* Change variable name `bool`, avoid conflict clang's predefined macro

### Removed

* `ps` command.

### Changed

* [#166](https://github.com/deivid-rodriguez/byebug/issues/166). Don't load
  the entire library on require, but only when a `byebug` call is issued. Thanks
  @bquorning.
* The above fix to the `finish 0` command cause `byebug`'s entrypoint to
  require 3 steps out instead of 2. In general, plugins using
  `Byebug::Context.step_out` will need to be changed to consider "c return
  events" as well.

### Added

* `autopry` setting that calls `pry` on every stop.
* Return value information to debugger's output when `finish 0` is used.

## 6.0.2 - 2015-08-20

### Fixed

* The user should always be given back a prompt unless (s)he explicitly states
  the opposite. This provides a more general fix to the bug resolved in 6.0.1.

## 6.0.1 - 2015-08-19

### Fixed

* Bug in evaluation where the user would lose the command prompt when entering
  an expression with a syntax error.

## 6.0.0 - 2015-08-17

### Removed

* `autoeval` setting. I haven't heard of anyone setting it to false.
* `pp`, `putl`, `eval`. People just want to evaluate Ruby code, so the less
  magic the better. Most of the people probably were not aware that `byebug`
  was overriding stuff like `pp` or `eval`. Only keeping `ps` as the single
  "enhanced evaluation" command.
* `verbose` setting.
* `info catch` command. Use `catch` without arguments instead.
* `R` command alias for `restart`.

### Changed

* `info args` is now `var args`.
* `interrupt` is now aliased to `int`, not to `i`.
* API to define custom commands and subcommands (see the Command class).

### Fixed

* [#140](https://github.com/deivid-rodriguez/byebug/issues/140). `help` command
  not showing the list of available commands and their descriptions.
* [#147](https://github.com/deivid-rodriguez/byebug/issues/147). Setting
  breakpoints at symlinked files.

### Added

* API to define custom command processors (see the CommandProcessor class).

## 5.0.0 - 2015-05-18

### Fixed

* [#136](https://github.com/deivid-rodriguez/byebug/issues/136). `frame`
  command not working with negative numbers (thanks @ark6).

### Added

* IDE support and a new command/subcommand API for plugins.
* Add a "savefile" setting holding the file where "save" command saves current
  debugger's state.

### Changed

* `disable` no longer disable all breakpoints, it just shows command's help
  instead. To disable all breakpoints now you need to do `disable breakpoints`
  (or `dis b`). Similarly, you can't no longer use `dis 1 2 3` but need to do
  `dis b 1 2 3` to disable specific breakpoints. The same applies to the
  `enable` command.

### Removed

* `help set <setting>` no longer works. `help set` includes that same output and
  it's not verbose enough so that this is a problem. Same with `help
  show <setting>`.

## 4.0.5 - 2015-04-02

### Fixed

* [#131](https://github.com/deivid-rodriguez/byebug/issues/131)
* Thread commands help format should be consistent with the rest of the help
  system now.

## 4.0.4 - 2015-03-27

### Fixed

* [#127](https://github.com/deivid-rodriguez/byebug/issues/127)

## 4.0.3 - 2015-03-19

### Fixed

* Unused variable warning in context.c

## 4.0.2 - 2015-03-16

### Fixed

* [#118](https://github.com/deivid-rodriguez/byebug/issues/118). Remove
  `rb-readline` as a dependency and show a help message whenever requiring
  `readline` fails instead.

## 4.0.1 - 2015-03-13

### Fixed

* .yml files needed for printers support were missing from the release... :S
* [#118](https://github.com/deivid-rodriguez/byebug/issues/118). Add `readline`
  as a dependency.

## 4.0.0 - 2015-03-13

### Added

* `untracevar` command that stops tracing a global variable.
* Window CI build through AppVeyor.
* OSX CI build through Travis.
* Style enforcement through RuboCop.
* C style enforment using the `indent` command line utility.
* Some remote debugging tests (thanks @eric-hu).
* Printer's support (thanks @astashov).

### Changed

* A lot of internal refactoring.
* `tracevar` now requires the full global variable name (with "$").
* [#92](https://github.com/deivid-rodriguez/byebug/issues/92). The `catch`
  command is not allowed in post_mortem mode anymore. It was not working anyways.
* [#85](https://github.com/deivid-rodriguez/byebug/issues/85). `step` is now
  more user friendly when used in combination with `up`.
* `var const` can now be called without an argument and will show constants in
  the current scope.
* `break` with a class name now creates breakpoints regardless of class not
  being yet defined. If that's the case, it gives a warning but the class is
  created anyways.

### Fixed

* Code reloading issues.
* `set fullpath` was not showing fullpaths. Now it is.
* `up`, `down` and `frame` commands now work in post_mortem mode (#93).
* rc file (`.byebugrc`) loading: invalid commands are just ignored instead of
  aborting, global (home) rc file is now properly loaded before project's file.
* [#93](https://github.com/deivid-rodriguez/byebug/issues/93). Backtraces not
  working in `post_mortem` mode.
* 'cmd1 ; cmd2 ; ...; cmdN' syntax which allows running several commands
  sequentially.
* [#101](https://github.com/deivid-rodriguez/byebug/issues/101). `finish`
  command not stopping at the correct line.
* [#106](https://github.com/deivid-rodriguez/byebug/issues/106). `break` with
  namespaced class, like `break A::B#c` should now work.
* Command history is now persisted before exiting byebug.
* Setting breakpoint in a method would stop not only at the beginning of the
  method but also at the beginning of every block inside the method.
* [#122](https://github.com/deivid-rodriguez/byebug/issues/122). Setting
  breakpoints on module methods (@x-yuri).

### Removed

* `autoreload` setting as it's not necessary anymore. Code should always be up
  to date.
* `reload` command for the same reason.
* Gem dependency on `debugger-linecache`.
* `step+`, `step-`, `next+`, `next-`, `set/show linetrace_plus` and
  `set/show forcestep` commands. These were all mechanisms to deal with
  TracePoint API event dupplication, but this duplicated events have been
  completely removed from the API since [r48609](
  bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/48609), so
  they are no longer necessary.
* `info file` subcommands: `info file breakpoints`, `info file mtime`, `info
  file sha1`, `info file all`. Now all information is listed under `info file`.
* `testing` setting. It was just a hack to be able to test `byebug`. Nobody was
  supposed to actually use it!
* `var class` command, just use Ruby (`self.class.class_variables`).
* `p` command, just use `eval`, or just type your expression and `byebug` will
  autoevaluate it.
* `exit` alias for `quit`.

## 3.5.1 - 2014-09-29

### Fixed

* [#79](https://github.com/deivid-rodriguez/byebug/issues/79). Windows
  installation.
* `condition` command not properly detecting invalid breakpoint ids.

## 3.5.0 - 2014-09-28

* User not being notified when trying to debug a non existent script.

### Changed

* Complete rewrite of byebug's history.

## 3.4.2 - 2014-09-26

### Fixed

* [#67](https://github.com/deivid-rodriguez/byebug/issues/67). Debugging
  commands invoked by ruby executable, as in `byebug -- ruby -Itest a_test.rb

* `backtrace` crashing when `fullpath` setting disabled and calculated stack
  size being smaller than the real one.

### Changed

* The `-t` option for `bin/byebug` now turns tracing on whereas the `-x` option
  tells byebug to run the initialization file (.byebugrc) on startup. This is
  the default behaviour though.
* `bin/byebug` libified and tests added.

### Removed

* `info locals` command. Use `var local` instead.
* `info instance_variables` command. Use `var instance` instead.
* `info global_variables` command. Use `var global` instead.

* `irb` command stepping capabilities, see
  [8e226d0](https://github.com/deivid-rodriguez/byebug/commit/8e226d0).

  (thanks @shuky19).
* [#69](https://github.com/deivid-rodriguez/byebug/issues/69). `source` command
  (thanks @Olgagr).
