=== 10.0.3

  "Jim, when will Rake reach version 1.0?"

Over the past several years I've been asked that question at
conferences, panels and over twitter. Due to historical reasons (or
maybe just plain laziness) Rake has (incorrectly) been treating the
second digit of the version as the major release number. So in my head
Rake was already at version 9.

Well, it's time to fix things. This next version of Rake drops old,
crufty, backwards compatibility hacks such as top level constants, DSL
methods defined in Object and numerous other features that are just no
longer desired. It's also time to drop the leading zero from the
version number as well and call this new version of rake what it
really is: Version 10.

So, welcome to Rake 10.0!

Rake 10 is actually feature identical to the latest version of Rake 9
(that would be the version spelled 0.9.3), *except* that Rake 10 drops
all the sundry deprecated features that have accumulated over the years.

If your Rakefile is up to date and current with all the new features
of Rake 10, you are ready to go. If your Rakefile still uses a few
deprecated feeatures, feel free to use Rake 9 (0.9.3) with the same
feature set. Just be aware that future features will be in Rake 10
family line.

==== Changes

As mentioned above, there are no new features in Rake 10. However,
there are a number of features missing:

* Classic namespaces are now gone. Rake is no longer able to reflect
  the options settings in the global variables ($rakefile, $show\_tasks,
  $show\_prereqs, $trace, $dryrun and $silent). The
  <tt>--classic-namespace</tt> option is no longer supported.

* Global constants are no longer supported. This includes
  <tt>Task</tt>, <tt>FileTask</tt>, <tt>FileCreationTask</tt> and
  <tt>RakeApp</tt>). The constant missing hook to warn about using
  global rake constants has been removed.

* The Rake DSL methods (task, file, directory, etc) are in their own
  module (Rake::DSL). The stub versions of these methods (that printed
  warnings) in Object have been removed. However, the DSL methods are
  added to the top-level <tt>main</tt> object. Since <tt>main</tt> is
  not in the inheritance tree, the presence of the DSL methods in main
  should be low impact on other libraries.

  If you want to use the Rake DSL commands from your own code, just
  include <tt>Rake::DSL</tt> into your own classes and modules.

* The deprecated syntax for task arguments (the one using
  <tt>:needs</tt>) has been removed.

* The <tt>--reduce-compat</tt> flag has been removed (it's not needed
  anymore).

* The deprecated <tt>rake/sys.rb</tt> library has been removed.

* The deprecated <tt>rake/rdoctask.rb</tt> library has been removed.
  RDoc supplies its own rake task now.

* The deprecated <tt>rake/gempackagetask.rb</tt> library has been
  removed. Gem supplies its own package task now.

There is one small behavioral change:

* Non-file tasks now always report the current time as their time
  stamp. This is different from the previous behavior where non-file
  tasks reported current time only if there were no prerequisites, and
  the max prerequisite timestamp otherwise. This lead to inconsistent
  and surprising behavior when adding prerequisites to tasks that in
  turn were prequisites to file tasks. The new behavior is more
  consistent and predictable.

==== Changes (from 0.9.3, 0.9.4, 0.9.5)

Since Rake 10 includes the changes from the last version of Rake 9,
we'll repeat the changes for versions 0.9.3 through 0.9.5 here.

===== New Features (in 0.9.3)

* Multitask tasks now use a thread pool. Use -j to limit the number of
  available threads.

* Use -m to turn regular tasks into multitasks (use at your own risk).

* You can now do "Rake.add_rakelib 'dir'" in your Rakefile to
  programatically add rake task libraries.

* You can specific backtrace suppression patterns (see
  --supress-backtrace)

* Directory tasks can now take prerequisites and actions

* Use --backtrace to request a full backtrace without the task trace.

* You can say "--backtrace=stdout" and "--trace=stdout" to route trace
  output to standard output rather than standard error.

* Optional 'phony' target (enable with 'require 'rake/phony'") for
  special purpose builds.

* Task#clear now clears task comments as well as actions and
  prerequisites. Task#clear_comment will specifically target comments.

* The --all option will force -T and -D to consider all the tasks,
  with and without descriptions.

===== Bug Fixes (in 0.9.3)

* Semi-colons in windows rakefile paths now work.

* Improved Control-C support when invoking multiple test suites.

* egrep method now reads files in text mode (better support for
  Windows)

* Better deprecation line number reporting.

* The -W option now works with all tasks, whether they have a
  description or not.

* File globs in rake should not be sorted alphabetically, independent
  of file system and platform.

* Numerous internal improvements.

* Documentation typos and fixes.

===== Bug Fixes (in 0.9.4)

* Exit status with failing tests is not correctly set to non-zero.

* Simplified syntax for phony task (for older versions of RDoc).

* Stand alone FileList usage gets glob function (without loading in
  extra dependencies)

===== Bug Fixes (in 0.9.5)

* --trace and --backtrace no longer swallow following task names.

=== 0.9.0

Rake version 0.9.0 has a number of bug fixes and enhancments (see
below for more details).  Additionally, the internals have be slightly
restructured and improved.

==== Changes

===== New Features / Enhancements / Bug Fixes in Version 0.9.0

* Rake now warns when the deprecated :needs syntax used (and suggests
  the proper syntax in the warning).

* Moved Rake DSL commands to top level ruby object 'main'.  Rake DSL
  commands are no longer private methods in Object. (Suggested by
  James M. Lawrence/quix)

* Rake now uses case-insensitive comparisons to find the Rakefile on Windows.
  Based on patch by Roger Pack.

* Rake now requires (instead of loads) files in the test task.  Patch by Cezary
  Baginski.

* Fixed typos.  Patches by Sean Scot August Moon and R.T. Lechow.

* Rake now prints the Rakefile directory only when it's different from the
  current directory.  Patch by Alex Chaffee.

* Improved rakefile_location discovery on Windows.  Patch by James Tucker.

* Rake now recognizes "Windows Server" as a windows system.  Patch by Matthias
  Lüdtke

* Rake::RDocTask is deprecated.  Use RDoc::Task from RDoc 2.4.2+ (require
  'rdoc/task')

* Rake::GemPackageTask is deprecated.  Use Gem::PackageTask (require
  'rubygems/package\_task')

* Rake now outputs various messages to $stderr instead of $stdout.

* Rake no longer emits warnings for Config.  Patch by Santiago Pastorino.

* Removed Rake's DSL methods from the top level scope.  If you need to
  call 'task :xzy' in your code, include Rake::DSL into your class, or
  put the code in a Rake::DSL.environment do ... end block.

* Split rake.rb into individual files.

* Support for the --where (-W) flag for showing where a task is defined.

* Fixed quoting in test task.
  (http://onestepback.org/redmine/issues/show/44,
  http://www.pivotaltracker.com/story/show/1223138)

* Fixed the silent option parsing problem.
  (http://onestepback.org/redmine/issues/show/47)

* Fixed :verbose=>false flag on sh and ruby commands.

* Rake command line options may be given by default in a RAKEOPT
  environment variable.

* Errors in Rake will now display the task invocation chain in effect
  at the time of the error.

* Accepted change by warnickr to not expand test patterns in shell
  (allowing more files in the test suite).

* Fixed that file tasks did not perform prereq lookups in scope
  (Redmine #57).

=== 0.8.4

Rake version 0.8.4 is a bug-fix release of rake.

NOTE: The version of Rake that comes with Ruby 1.9 has diverged
      slightly from the core Rake code base.  Rake 0.8.4 will work
      with Ruby 1.9, but is not a strict upgrade for the Rake that
      comes with Ruby 1.9.  A (near) future release of Rake will unify
      those two codebases.

==== Letter Writing Campaign

Thanks to Aaron Patterson (@tenderlove) and Eric Hodel (@drbrain) for
their encouraging support in organizing a letter writing campaign to
lobby for the "Warning Free" release of rake 0.8.4.  A special callout
goes to Jonathan D. Lord, Sr (Dr. Wingnut) whose postcard was the
first to actually reach me. (see
http://tenderlovemaking.com/2009/02/26/we-need-a-new-version-of-rake/
for details)

==== Changes

===== New Features / Enhancements in Version 0.8.4

* Case is preserved on rakefile names. (patch from James
  M. Lawrence/quix)

* Improved Rakefile case insensitivity testing (patch from Luis
  Lavena).

* Windows system dir search order is now: HOME, HOMEDRIVE + HOMEPATH,
  APPDATA, USERPROFILE (patch from Luis Lavena)

* MingGW is now recognized as a windows platform.  (patch from Luis
  Lavena)

===== Bug Fixes in Version 0.8.4

* Removed reference to manage_gem to fix the warning produced by the
  gem package task.

* Fixed stray ARGV option problem that was interfering with
  Test::Unit::Runner. (patch from Pivotal Labs)

===== Infrastructure Improvements in Version 0.8.4

* Numerous fixes to the windows test suite (patch from Luis Lavena).

=== 0.8.3

Rake version 0.8.3 is a bug-fix release of rake.

==== Changes

===== Bug Fixes in Version 0.8.3

* Enhanced the system directory detection in windows. We now check
  HOMEDRIVE/HOMEPATH and USERPROFILE if APPDATA isn't found. (Patch
  supplied by James Tucker). Rake no long aborts if it can't find the
  directory.

* Added fix to handle ruby installations in directories with spaces in
  their name.

=== 0.8.2

Rake version 0.8.2 is a new release of rake that includes a number of
new features and numerous bug fixes.

==== Changes

===== New Features in Version 0.8.2

* Switched from getoptlong to optparse (patches supplied by Edwin
  Pratomo).

* The -T option will now attempt to dynamically sense the size of the
  terminal. The -T output will only self-truncate if the output is a
  tty. However, if RAKE_COLUMNS is explicitly set, it will be honored
  in any case. (Patch provided by Gavin Stark).

* The following public methods have been added to rake task objects:

  * task.clear -- Clear both the prerequisites and actions of the
    target rake task.
  * task.clear_prerequisites -- Clear all the existing prerequisites
    from the target rake task.
  * task.clear_actions -- Clear all the existing actions from the
    target rake task.
  * task.reenable -- Re-enable a task, allowing its actions to be
    executed again if the task is invoked.

* Changed RDoc test task to have no default template. This makes it
  easier for the tempate to pick up the template from the environment.

* Default values for task arguments can easily be specified with the
  :with_defaults method. (Idea for default argument merging supplied
  by (Adam Q. Salter)

===== Bug Fixes in Version 0.8.2

* Fixed bug in package task so that it will include the subdir
  directory in the package for testing. (Bug found by Adam Majer)

* Fixed filename dependency order bug in test\_inspect\_pending and
  test\_to\_s\_pending. (Bug found by Adam Majer)

* Fixed check for file utils options to make them immune to the
  symbol/string differences. (Patch supplied by Edwin Pratomo)

* Fixed bug with rules involving multiple source, where only the first
  dependency of a rule has any effect (Patch supplied by Emanuel
  Indermühle)

* FileList#clone and FileList#dup have better sematics w.r.t. taint
  and freeze.

* Changed from using Mutex to Monitor. Evidently Mutex causes thread
  join errors when Ruby is compiled with -disable-pthreads. (Patch
  supplied by Ittay Dror)

* Fixed bug in makefile parser that had problems with extra spaces in
  file task names. (Patch supplied by Ittay Dror)

==== Other changes in Version 0.8.2

* Added ENV var to rake's own Rakefile to prevent OS X from including
  extended attribute junk in the rake package tar file. (Bug found by
  Adam Majer)

* Added a performance patch for reading large makefile dependency
  files. (Patch supplied by Ittay Dror)

==== Task Argument Examples

Prior to version 0.8.0, rake was only able to handle command line
arguments of the form NAME=VALUE that were passed into Rake via the
ENV hash.  Many folks had asked for some kind of simple command line
arguments, perhaps using "--" to separate regular task names from
argument values on the command line.  The problem is that there was no
easy way to associate positional arguments on the command line with
different tasks.  Suppose both tasks :a and :b expect a command line
argument: does the first value go with :a?  What if :b is run first?
Should it then get the first command line argument.

Rake 0.8.0 solves this problem by explicitly passing values directly
to the tasks that need them.  For example, if I had a release task
that required a version number, I could say:

   rake release[0.8.2]

And the string "0.8.2" will be passed to the :release task.  Multiple
arguments can be passed by separating them with a comma, for example:

   rake name[john,doe]

Just a few words of caution.  The rake task name and its arguments
need to be a single command line argument to rake.  This generally
means no spaces.  If spaces are needed, then the entire rake +
argument string should be quoted.  Something like this:

   rake "name[billy bob, smith]"

(Quoting rules vary between operating systems and shells, so make sure
you consult the proper docs for your OS/shell).

===== Tasks that Expect Parameters

Parameters are only given to tasks that are setup to expect them.  In
order to handle named parameters, the task declaration syntax for
tasks has been extended slightly.

For example, a task that needs a first name and last name might be
declared as:

   task :name, :first_name, :last_name

The first argument is still the name of the task (:name in this case).
The next to argumements are the names of the parameters expected by
:name (:first_name and :last_name in the example).

To access the values of the paramters, the block defining the task
behaviour can now accept a second parameter:

   task :name, :first_name, :last_name do |t, args|
     puts "First name is #{args.first_name}"
     puts "Last  name is #{args.last_name}"
   end

The first argument of the block "t" is always bound to the current
task object.  The second argument "args" is an open-struct like object
that allows access to the task arguments.  Extra command line
arguments to a task are ignored.  Missing command line arguments are
given the nil value.

=== 0.8.0/0.8.1

Rake version 0.8.0 is a new release of rake that includes serveral new
features.

==== Changes

===== New Features in Version 0.8.0

* Tasks can now receive command line parameters.  See the examples
  below for more details.

* Comments are limited to 80 columns on output, but full comments can
  be seen by using the -D parameter. (feature suggested by Jamis
  Buck).

* Explicit exit(n) calls will now set the exit status to n. (patch
  provided by Stephen Touset).

* Rake is now compatible with Ruby 1.9.

Version 0.8.1 is a minor update that includes additional Ruby 1.9
compatibility fixes.

=== 0.7.3

Rake version 0.7.3 is a minor release that includes some refactoring to better
support custom Rake applications.

==== Changes

===== New Features in Version 0.7.3

* Added the +init+ and +top_level+ methods to make the creation of custom Rake applications a bit easier.  E.g.

    gem 'rake', ">= 0.7.3"
    require 'rake'

    Rake.application.init('myrake')

    task :default do
      something_interesting

=== 0.7.2


Version 0.7.2 supplies a bug fix and a few minor enhancements. In
particular, the new version fixes an incompatibility with the soon to
be released Ruby 1.8.6.  We strongly recommend upgrading to Rake 0.7.2
in order to be compatible with the new version of Ruby.

==== Changes

===== Bug Fixes in 0.7.2

There are quite a number of bug fixes in the new 0.7.2 version of
Rake:

* Removed dependency on internal fu_xxx functions from FileUtils.

* Error messages are now send to stderr rather than stdout (from
  Payton Quackenbush).

* Better error handling on invalid command line arguments (from Payton
  Quackenbush).

* Fixed some bugs where the application object was going to the global
  appliation instead of using its own data.

* Fixed the method name leak from FileUtils (bug found by Glenn
  Vanderburg).

* Added test for noop, bad_option and verbose flags to sh command.

* Added a description to the gem task in GemPackageTask.

* Fixed a bug when rules have multiple prerequisites (patch by Joel
  VanderWerf)

* Added the handful of RakeFileUtils to the private method as well.

===== New Features in 0.7.2

The following new features are available in Rake version 0.7.2:

* Added square and curly bracket patterns to FileList#include (Tilman
  Sauerbeck).

* FileLists can now pass a block to FileList#exclude to exclude files
  based on calculated values.

* Added plain filename support to rule dependents (suggested by Nobu
  Nakada).

* Added pathmap support to rule dependents.  In other words, if a
  pathmap format (beginning with a '%') is given as a Rake rule
  dependent, then the name of the depend will be the name of the
  target with the pathmap format applied.

* Added a 'tasks' method to a namespace to get a list of tasks
  associated with the namespace.

* Added tar_command and zip_command options to the Package task.

* The clean task will no longer delete 'core' if it is a directory.

===== Internal Rake Improvements

The following changes will are mainly internal improvements and
refactorings and have little effect on the end user.  But they may be
of interest to the general public.

* Added rcov task and updated unit testing for better code coverage.

* Added a 'shame' task to the Rakefile.

* Added rake_extension to handle detection of extension collisions.

* Added a protected 'require "rubygems"' to test/test_application to
  unbreak cruisecontrol.rb.

* Removed rake\_dup.  Now we just simply rescue a bad dup.

* Refactored the FileList reject logic to remove duplication.

* Removed if \_\_FILE\_\_ at the end of the rake.rb file.

==== Thanks

As usual, it was input from users that drove a alot of these changes.
The following people either contributed patches, made suggestions or
made otherwise helpful comments.  Thanks to ...

* Payton Quackenbush -- For several error handling improvements.

* Glenn Vanderburg -- For finding and fixing the method name leak from
  FileUtils.

* Joel VanderWerf -- for finding and fixing a bug in the handling of
  multiple prerequisites.

* Tilman Sauerbeck -- For some enhancing FileList to support more
  advanced file globbing.

* Nobu Nakada -- For suggesting plain file name support to rule dependents.

-- Jim Weirich

=== 0.7.1

Version 0.7.1 supplies a bug fix and a few minor enhancements.

==== Changes

===== Bug Fixes in 0.7.1

* Changes in the exception reported for the FileUtils.ln caused
  safe_ln to fail with a NotImplementedError.  Rake 0.7.1 will now
  catch that error or any StandardError and properly fall back to
  using +cp+.

===== New Features in 0.7.1

* You can filter the results of the --task option by supplying an
  optional regular expression.  This allows the user to easily find a
  particular task name in a long list of possible names.

* Transforming procs in a rule may now return a list of prerequisites.
  This allows more flexible rule formation.

* FileList and String now support a +pathmap+ melthod that makes the
  transforming paths a bit easier.  See the API docs for +pathmap+ for
  details.

* The -f option without a value will disable the search for a
  Rakefile.  This allows the Rakefile to be defined entirely in a
  library (and loaded with the -r option).  The current working
  directory is not changed when this is done.

==== Thanks

As usual, it was input from users that drove a alot of these changes.
The following people either contributed patches, made suggestions or

* James Britt and Assaph Mehr for reporting and helping to debug the
  safe_ln issue.

-- Jim Weirich


=== 0.7.0

These changes for Rake have been brewing for a long time.  Here they
are, I hope you enjoy them.

==== Changes

===== New Features

* Name space support for task names (see below).
* Prerequisites can be executed in parallel (see below).
* Added safe_ln support for openAFS (via Ludvig Omholt).
* RDoc defaults to internal (in-process) invocation.  The old behavior
  is still available by setting the +external+ flag to true.
* Rakefiles are now loaded with the expanded path to prevent
  accidental polution from the Ruby load path.
* Task objects my now be used in prerequisite lists directly.
* Task objects (in addition to task names) may now be included in the
  prerequisite list of a task.
* Internals cleanup and refactoring.

===== Bug Fixes

* Compatibility fixes for Ruby 1.8.4 FileUtils changes.

===== Namespaces

Tasks can now be nested inside their own namespaces.  Tasks within one
namespace will not accidently interfer with tasks named in a different
namespace.

For example:

  namespace "main" do
    task :build do
      # Build the main program
    end
  end

  namespace "samples" do
    task :build do
      # Build the sample programs
    end
  end

  task :build_all => ["main:build", "samples:build"]

Even though both tasks are named :build, they are separate tasks in
their own namespaces.  The :build_all task (defined in the toplevel
namespace) references both build tasks in its prerequisites.

You may invoke each of the individual build tasks with the following
commands:

  rake main:build
  rake samples:build

Or invoke both via the :build_all command:

  rake build_all

Namespaces may be nested arbitrarily.  Since the name of file tasks
correspond to the name of a file in the external file system,
FileTasks are not affected by the namespaces.

See the Rakefile format documentation (in the Rake API documents) for
more information.

===== Parallel Tasks

Sometimes you have several tasks that can be executed in parallel.  By
specifying these tasks as prerequisites to a +multitask+ task.

In the following example the tasks copy\_src, copy\_doc and copy\_bin
will all execute in parallel in their own thread.

  multitask :copy_files => [:copy_src, :copy_doc, :copy_bin] do
    puts "All Copies Complete"
  end

==== Thanks

As usual, it was input from users that drove a alot of these changes.
The following people either contributed patches, made suggestions or
made otherwise helpful comments.  Thanks to ...

* Doug Young (inspriation for the parallel task)
* David Heinemeier Hansson (for --trace message enhancement and for
  pushing for namespace support).
* Ludvig Omholt (for the openAFS fix)

-- Jim Weirich

=== 0.6.1

* Rebuilt 0.6.0 gem without signing.

=== 0.6.0

Its time for some long requested enhancements and lots of bug fixes
... And a whole new web page.

==== New Web Page

The primary documentation for rake has moved from the RubyForge based
wiki to its own Hieraki based web site.  Constant spam on the wiki
made it a difficult to keep clean.  The new site will be easier to
update and organize.

Check out the new documentation at: http://docs.rubyrake.org

We will be adding new documentation to the site as time goes on.

In addition to the new docs page, make sure you check out Martin
Fowlers article on rake at http://martinfowler.com/articles/rake.html

==== Changes

===== New Features

* Multiple prerequisites on Rake rules now allowed.  However, keep the
  following in mind:

  1. All the prerequisites of a rule must be available before a rule
     is triggered, where "enabled" means (a) an existing file, (b) a
     defined rule, or (c) another rule which also must be
     trigger-able.
  2. Rules are checked in order of definition, so it is important to
     order your rules properly.  If a file can be created by two
     different rules, put the more specific rule first (otherwise the
     more general rule will trigger first and the specific one will
     never be triggered).
  3. The <tt>source</tt> method now returns the name of the first
     prerequisite listed in the rule.  <tt>sources</tt> returns the
     names of all the rule prerequisites, ordered as they are defined
     in the rule.  If the task has other prerequisites not defined in
     the rule (but defined in an explicit task definition), then they
     will _not_ be included in the sources list.

* FileLists may now use the egrep command.  This popular enhancement
  is now a core part of the FileList object.  If you want to get a
  list of all your to-dos, fixmes and TBD comments, add the following
  to your Rakefile.

    desc "Look for TODO and FIXME tags in the code"
    task :todo do
      FileList['**/*.rb'].egrep /#.*(FIXME|TODO|TBD)/
    end

* The <tt>investigation</tt> method was added to task object to dump
  out some important values.  This makes it a bit easier to debug Rake
  tasks.

  For example, if you are having problems with a particular task, just
  print it out:

    task :huh do
      puts Rake::Task['huh'].investigation
    end

* The Rake::TestTask class now supports a "ruby\_opts" option to pass
  arbitrary ruby options to a test subprocess.

===== Some Incompatibilities

* When using the <tt>ruby</tt> command to start a Ruby subprocess, the
  Ruby interpreter that is currently running rake is used by default.
  This makes it easier to use rake in an environment with multiple
  ruby installation.  (Previously, the first ruby command found in the
  PATH was used).

  If you wish to chose a different Ruby interpreter, you can
  explicitly choose the interpreter via the <tt>sh</tt> command.

* The major rake classes (Task, FileTask, FileCreationTask, RakeApp)
  have been moved out of the toplevel scope and are now accessible as
  Rake::Task, Rake::FileTask, Rake::FileCreationTask and
  Rake::Application.  If your Rakefile
  directly references any one of these tasks, you may:

  1. Update your Rakefile to use the new classnames
  2. Use the --classic-namespace option on the rake command to get the
     old behavior,
  3. Add <code>require 'rake/classic_namespace'</code> to the
     Rakefile to get the old behavior.

  <tt>rake</tt> will print a rather annoying warning whenever a
  deprecated class name is referenced without enabling classic
  namespace.

===== Bug Fixes

* Several unit tests and functional tests were fixed to run better
  under windows.

* Directory tasks are now a specialized version of a File task.  A
  directory task will only be triggered if it doesn't exist.  It will
  not be triggered if it is out of date w.r.t. any of its
  prerequisites.

* Fixed a bug in the Rake::GemPackageTask class so that the gem now
  properly contains the platform name.

* Fixed a bug where a prerequisite on a <tt>file</tt> task would cause
  an exception if the prerequisite did not exist.

=== 0.5.4

Time for some minor bug fixes and small enhancements

==== Changes

Here are the changes for version 0.5.4 ...

* Added double quotes to the test runner.  This allows the location of
  the tests (and runner) to be in a directory path that contains
  spaces (e.g. "C:/Program Files/ruby/bin").
* Added .svn to default ignore list.  Now subversion project metadata
  is automatically ignored by Rake's FileList.
* Updated FileList#include to support nested arrays and filelists.
  FileLists are flat lists of file names.  Using a FileList in an
  include will flatten out the nested file names.

== Thanks

As usual, it was input from users that drove a alot of these changes.
Thanks to ...

* Tilman Sauerbeck for the nested FileList suggestion.
* Josh Knowles for pointing out the spaces in directory name problem.

=== 0.5.3

Although it has only been two weeks since the last release, we have
enough updates to the Rake program to make it time for another
release.

==== Changes

Here are the changes for version 0.5.3 ...

* FileLists have been extensively changed so that they mimic the
  behavior of real arrays even more closely.  In particular,
  operations on FileLists that return a new collection (e.g. collect,
  reject) will now return a FileList rather than an array.  In
  addition, several places where FileLists were not properly expanded
  before use have been fixed.
* A method (+ext+) to simplify the handling of file extensions was
  added to String and to Array.
* The 'testrb' script in test/unit tends to silently swallow syntax
  errors in test suites.  Because of that, the default test loader is
  now a rake-provided script.  You can still use 'testrb' by setting
  the loader flag in the test task to :testrb.  (See the API documents
  for TestTask for all the loader flag values).
* FileUtil methods (e.g. cp, mv, install) are now declared to be
  private.  This will cut down on the interference with user defined
  methods of the same name.
* Fixed the verbose flag in the TestTask so that the test code is
  controlled by the flag.  Also shortened up some failure messages.
  (Thanks to Tobias Luetke for the suggestion).
* Rules will now properly detect a task that can generate a source
  file.  Previously rules would only consider source files that were
  already present.
* Added an +import+ command that allows Rake to dynamically import
  dependendencies into a running Rake session.  The +import+ command
  can run tasks to update the dependency file before loading them.
  Dependency files can be in rake or make format, allowing rake to
  work with tools designed to generate dependencies for make.

==== Thanks

As usual, it was input from users that drove a alot of these changes.
Thanks to ...

* Brian Gernhardt for the rules fix (especially for the patience to
  explain the problem to me until I got what he was talking about).
* Stefan Lang for pointing out problems in the dark corners of the
  FileList implementation.
* Alexey Verkhovsky pointing out the silently swallows syntax errors
  in tests.
* Tobias Luetke for beautifying the test task output.
* Sam Roberts for some of the ideas behind dependency loading.

=== 0.5.0

It has been a long time in coming, but we finally have a new version
of Rake available.

==== Changes

* Fixed documentation that was lacking the Rake module name (Tilman
  Sauerbeck).
* Added tar.gz and tar.bz2 support to package task (Tilman Sauerbeck).
* Recursive rules are now supported (Tilman Sauerbeck).
* Added warning option for the Test Task (requested by Eric Hodel).
* The jamis rdoc template is only used if it exists.
* Added fix for Ruby 1.8.2 test/unit and rails problem.
* Added contributed rake man file (Jani Monoses).
* Added Brian Candler's fix for problems in --trace and --dry-run
  mode.

==== Thanks

Lots of people provided input to this release.  Thanks to Tilman
Sauerbeck for numerous patches, documentation fixes and suggestions.
And for also pushing me to get this release out.  Also, thanks to
Brian Candler for the finding and fixing --trace/dry-run fix.  That
was an obscure bug.  Also to Eric Hodel for some good suggestions.

=== 0.4.15

==== Changes

Version 0.4.15 is a bug fix update for the Ruby 1.8.2 compatibility
changes.  This release includes:

* Fixed a bug that prevented the TESTOPTS flag from working with the
  revised for 1.8.2 test task.
* Updated the docs on --trace to indicate that it also enables a full
  backtrace on errors.
* Several fixes for new warnings generated.

==== Mini-Roadmap

I will continue to issue Rake updates in the 0.4.xx series as new
Ruby-1.8.2 issues become manifest.  Once the codebase stabilizes, I
will release a 0.5.0 version incorporating all the changes.  If you
are not using Ruby-1.8.2 and wish to avoid version churn, I recommend
staying with a release prior to Rake-0.4.14.

=== 0.4.14

Version 0.4.14 is a compatibility fix to allow Rake's test task to
work under Ruby 1.8.2.  A change in the Test::Unit autorun feature
prevented Rake from running any tests.  This release fixes the
problem.

Rake 0.4.14 is the recommended release for anyone using Ruby 1.8.2.

=== 0.4.13

* Fixed the dry-run flag so it is operating again.
* Multiple arguments to sh and ruby commands will not be interpreted
  by the shell (patch provided by Jonathan Paisley).

=== 0.4.12

* Added --silent (-s) to suppress the (in directory) rake message.

=== 0.4.11

* Changed the "don't know how to rake" message (finally)
* Changes references to a literal "Rakefile" to reference the global
  variable $rakefile (which contains the actual name of the rakefile).

=== 0.4.10

* Added block support to the "sh" command, allowing users to take
  special actions on the result of the system call.  E.g.

    sh "shell_command" do |ok, res|
      puts "Program returned #{res.exitstatus}" if ! ok
    end

=== 0.4.9

* Switched to Jamis Buck's RDoc template.
* Removed autorequire from Rake's gem spec.  This prevents the Rake
  libraries from loading while using rails.

=== 0.4.8

* Added support for .rb versions of Rakefile.
* Removed \\\n's from test task.
* Fixed Ruby 1.9 compatibility issue with FileList.

=== 0.4.7

* Fixed problem in FileList that caused Ruby 1.9 to go into infinite
  recursion.  Since to_a was removed from Object, it does not need to
  added back into the list of methods to rewrite in FileList.  (Thanks
  to Kent Sibilev for pointing this out).

=== 0.4.6
* Removed test version of ln in FileUtils that prevented safe_ln from
  using ln.

=== 0.4.5
* Upgraded comments in TestTask.
* FileList to_s and inspect now automatically resolve pending changes.
* FileList#exclude properly returns the FileList.

=== 0.4.4
* Fixed initialization problem with @comment.
* Now using multi -r technique in TestTask.  Switch Rakefile back to
  using the built-in test task macros because the rake runtime is no
  longer needed.
* Added 'TEST=filename' and 'TESTOPTS=options' to the Test Task
  macros.
* Allow a +test_files+ attribute in test tasks.  This allows more
  flexibility in specifying test files.

=== 0.4.3
* Fixed Comment leakage.

=== 0.4.2
* Added safe_ln that falls back to a copy if a file link is not supported.
* Package builder now uses safe\_ln.

=== 0.4.1
* Task comments are now additive, combined with "/".
* Works with (soon to be released) rubygems 0.6.2 (or 0.7.0)

=== 0.4.0
* FileList now uses deferred loading.  The file system is not searched
  until the first call that needs the file names.
* VAR=VALUE options are now accepted on the command line and are
  treated like environment variables.  The values may be tested in a
  Rakefile by referencing ENV['VAR'].
* File.mtime is now used (instead of File.new().mtime).

=== 0.3.2.x

* Removed some hidden dependencies on rubygems.  Tests now will test
  gems only if they are installed.
* Removed Sys from some example files.  I believe that is that last
  reference to Sys outside of the contrib area.
* Updated all copyright notices to include 2004.

=== 0.3.2

* GEM Installation now works with the application stub.

=== 0.3.1

* FileLists now automatically ignore CVS, .bak, !
* GEM Installation now works.

=== 0.3.0

Promoted 0.2.10.

=== 0.2.10
General

* Added title to Rake's rdocs
* Contrib packages are no longer included in the documentation.

RDoc Issues

* Removed default for the '--main' option
* Fixed rendering of the rdoc options
* Fixed clean/clobber confusion with rerdoc
* 'title' attribute added

Package Task Library Issues

* Version (or explicit :noversion) is required.
* +package_file+ attribute is now writable

FileList Issues

* Dropped bang version of exclude.  Now using ant-like include/exclude semantics.
* Enabled the "yield self" idiom in FileList#initialize.

=== 0.2.9

This version contains numerous changes as the RubyConf.new(2003)
presentation was being prepared.  The changes include:

* The monolithic rubyapp task library is in the process of being
  dropped in favor of lighter weight task libraries.

=== 0.2.7

* Added "desc" for task descriptions.
* -T will now display tasks with descriptions.
* -P will display tasks and prerequisites.
* Dropped the Sys module in favor of the 1.8.x FileUtils module.  Sys
  is still supported in the contrib area.

=== 0.2.6

* Moved to RubyForge

=== 0.2.5

* Switched to standard ruby app builder.
* Added no_match option to file matcher.

=== 0.2.4

* Fixed indir, which neglected to actually change directories.

=== 0.2.3

* Added rake module for a help target
* Added 'for\_files' to Sys
* Added a $rakefile constant
* Added test for selecting proper rule with multiple targets.
