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 --classic-namespace option is no longer supported.
Global constants are no longer supported. This includes Task, FileTask, FileCreationTask and RakeApp). 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 main object. Since main 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 Rake::DSL into your own classes and modules.
The deprecated syntax for task arguments (the one using :needs) has been removed.
The --reduce-compat flag has been removed (it’s not needed anymore).
The deprecated rake/sys.rb library has been removed.
The deprecated rake/rdoctask.rb library has been removed. RDoc supplies its own rake task now.
The deprecated rake/gempackagetask.rb 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 –suppress-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.

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. (onestepback.org/redmine/issues/show/44, www.pivotaltracker.com/story/show/1223138)
Fixed the silent option parsing problem. (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 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
1. 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).
Improved Rakefile case insensitivity testing (patch from Luis Lavena).

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 parameters, 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
end

Rake.application.top_level

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 made otherwise helpful comments. Thanks to …

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 pollution 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 accidentally 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

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: 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 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 © 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 source method now returns the name of the first prerequisite listed in the rule. sources 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 investigation 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 ruby 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 sh 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 require 'rake/classic_namespace' to the Rakefile to get the old behavior.
rake 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 file task would cause an exception if the prerequisite did not exist.

– Jim Weirich

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.

– Jim Weirich

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.

– Jim Weirich

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.
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.

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.
