### Default task
task :default  => [:clean, :build, :spec, :verify, :package]


### Task: clean
desc "Clean pkg, coverage, and rdoc; remove .bak files"
task :clean => [ :clobber_rdoc, :clobber_package, :clobber_coverage, :clobber_manual ] do
	files = FileList['**/*.bak']
	files.clear_exclude
	File.rm( files ) unless files.empty?
	FileUtils.rm_rf( 'artifacts' )
end


### Task: docs -- Convenience task for rebuilding dynamic docs, including coverage, api 
### docs, and manual
multitask :docs => [ :manual, :coverage, :rdoc ] do
	log "All documentation built."
end


### Task: generate ctags
### This assumes exuberant ctags, since ctags 'native' doesn't support ruby anyway.
desc "Generate a ctags 'tags' file from ThingFish source"
task :ctags do
	run %w{ ctags -R lib plugins misc }
end


### Cruisecontrol task
desc "Cruisecontrol build"
task :cruise => [:clean, 'spec:text', :package] do |task|
	raise "Artifacts dir not set." if ARTIFACTS_DIR.to_s.empty?
	artifact_dir = ARTIFACTS_DIR.cleanpath
	artifact_dir.mkpath
	
	$stderr.puts "Copying coverage stats..."
	FileUtils.cp_r( 'coverage', artifact_dir )
	
	$stderr.puts "Copying packages..."
	FileUtils.cp_r( FileList['pkg/*'].to_a, artifact_dir )
