SourceAnnotationExtractor

rails latest stable - Superclass: Object

Class deprecated or moved

This class is deprecated or moved on the latest stable version. The last existing version (v5.2.3) is shown here.

Implements the logic behind the rake tasks for annotations like

rails notes
rails notes:optimize

and friends. See rails -T notes and railties/lib/rails/tasks/annotations.rake.

Annotation objects are triplets :line, :tag, :text that represent the line where the annotation lives, its tag, and its text. Note the filename is not stored.

Annotations are looked for in comments and modulus whitespace they have to start with the tag optionally followed by a colon. Everything up to the end of the line (or closing ERB comment tag) is considered to be their text.

Custom annotation types

noxyu3m · Jul 23, 20085 thanks

For group work you may need something more than FIXME, OPTIMIZE and TODO. Just create new rake file and place it to lib/tasks:

require 'source_annotation_extractor'

task :notes do
SourceAnnotationExtractor.enumerate "WTF|OMG", :tag => true
end

namespace :notes do
desc "Enumerate all WTF annotations"
task :wtf do
  SourceAnnotationExtractor.enumerate "WTF"
end

desc "Enumerate all OMG annotations"
task :omg do
  SourceAnnotationExtractor.enumerate "OMG"
end
end

or create an array of new types and generate tasks dynamicaly.

Add Rspec files to the annotations

pallan · Jan 27, 20091 thank

By default the annotations search the 'test' folder, but not the 'spec' folder if you are using Rspec. To get those specs involved do this:

require 'source_annotation_extractor'

class SourceAnnotationExtractor
def find(dirs=%w(app lib spec))
  dirs.inject({}) { |h, dir| h.update(find_in(dir)) }
end
end

If you have other folders you want to check, just add them to the dirs list.
