Instance Method Summary collapse
- #java_platform? ⇒ Boolean
-
#normalize_path(path, *dirs) ⇒ Object
Just like File.expand_path, but for windows systems it capitalizes the drive name and ensures backslashes are used.
-
#recursive_with_dot_files(*dirs) ⇒ Object
Generally speaking, it’s not a good idea to operate on dot files (files starting with dot).
-
#relative_path(to, from = '.') ⇒ Object
Return the path to the first argument, starting from the path provided by the second argument.
-
#ruby(*args) ⇒ Object
Runs Ruby with these command line arguments.
-
#timestamp(file) ⇒ Object
Return the timestamp of file, without having to create a file task.
-
#win_os? ⇒ Boolean
In order to determine if we are running on a windows OS, prefer this function instead of using Gem.win_platform?.

# File 'lib/buildr/core/util.rb', line 72 def normalize_path(path, *dirs) path = File.(path, *dirs) if win_os? path.gsub!('/', '\\').gsub!(/^[a-zA-Z]+:/) { |s| s.upcase } else path end end |
#recursive_with_dot_files(*dirs) ⇒ Object
Generally speaking, it’s not a good idea to operate on dot files (files starting with dot). These are considered invisible files (.svn, .hg, .irbrc, etc). Dir.glob/FileList ignore them on purpose. There are few cases where we do have to work with them (filter, zip), a better solution is welcome, maybe being more explicit with include. For now, this will do.

# File 'lib/buildr/core/util.rb', line 114 def recursive_with_dot_files(*dirs) FileList[dirs.map { |dir| File.join(dir, '/**/{*,.*}') }].reject { |file| File.basename(file) =~ /^[.]{1,2}$/ } end |
#relative_path(to, from = '.') ⇒ Object
Return the path to the first argument, starting from the path provided by the second argument.
For example:
relative_path('foo/bar', 'foo')
=> 'bar'
relative_path('foo/bar', 'baz')
=> '../foo/bar'
relative_path('foo/bar')
=> 'foo/bar'
relative_path('/foo/bar', 'baz')
=> '/foo/bar'

#ruby(*args) ⇒ Object
Runs Ruby with these command line arguments. The last argument may be a hash, supporting the following keys:
:command -- Runs the specified script (e.g., :command=>'gem')
:sudo -- Run as sudo on operating systems that require it.
:verbose -- Override Rake's verbose flag.

#win_os? ⇒ Boolean
In order to determine if we are running on a windows OS, prefer this function instead of using Gem.win_platform?.
Gem.win_platform? only checks these RUBY_PLATFORM global, that in some cases like when running on JRuby is not succifient for our purpose:
For JRuby, the value for RUBY_PLATFORM will always be ‘java’ That’s why this function checks on Config::CONFIG
