Rake FileList not working?

ruby-talk
1

In my Rakefile (given in earlier post):

  PKG_FILES = FileList[
    "lib/**/*",
    "test/**/*",
    "examples/**/*",
    "doc/**/*",
    "[A-Z]*",
    "install.rb",
    "Rakefile"
  ].exclude(/\bCVS\b|~$/)
  p PKG_FILES.class

  # => NilClass

Huh?

(1) Remove the exclude call. You don't need it. FileLists are smart enough to automatically exclude CVS directories and backup files.

(2) If you do need exclude, put it in a separate step. E.g.

   PKG_FILES = FileList['blah*.rb']
   PKG_FILES.exclude(/.*test.rb/)

Exclude must not be returning the filelist. That is a bug. I'll fix it in the next release.

Thanks for the heads up.

No, No, Thank You! :slight_smile:

BTW, how do I give the RDocTask a prerequisite?

Thanks again,

I'm confused... Isn't FileList#exclude supposed to return an array of strings, not a FileList? (Rake 0.4.3, anyway)

Prerequisites can be added to a task at any time. Just redeclare the task
and the prerequisites and action will be appended to the existing task.

For example:

  task :build => [:preprocess, :compile, :link]

is equivalent to ...

  task :build => [:preprocess]
  task :build => [:compile]
  task :build => [:link]

So, to add a prereq to the :rdoc task ...

  task :rdoc => [:whatever]

Well, exclude should return a list of strings (actually a list of file
names). The type of list it returns is a FileList. And since FileList
acts a lot like an array (through the magic of DuckTyping), returning the
file list object *is* returning an array of strings ... it's just not an
Array of strings.
