Snippets for Ruby testing assertions don't generate correctly

Reported by Stuart Ellis | March 11th, 2010 @ 01:50 PM

Snippets for Ruby assertions don't create substitution sections correctly. Other snippets for Ruby tests work correctly.

Observed on Windows XP SP3 with Redcar 0.3.4.

To reproduce:

  • Open a text file with a .rb extension
  • Choose Bundles > Ruby > Tests
  • Choose assert_equal

The following appears in the text file:

assert_equalsnippet_paren.rbexpected, actualsnippet_paren.rb end

assert_instance_of, assert_match etc. have the same behavior, as does flunk.

    Yep. This is a tricky one. That snippet_paren.rb thing means run this Ruby script and substitute in the result.

    We're not planning to support the running of arbitrary shell code, because it's a big pain to make it cross platform. So we're going to have to replace this snippet (and others like it) with something that does something similar inside the Redcar application.

    I suppose something like:

    assert_equal`Ruby::SnippetSupport.snippet_paren`expected, actual`Ruby::SnippetSupport.snippet_paren`

    and a corresponding class that Redcar makes available in the snippet context:

    class Ruby::SnippetSupport
      def self.snippet_paren
        # port the snippet_paren.rb code to here...

    ... would do the job.

    • Tag changed from snippets ruby test to snippet

    Like the backticks for ruby idea. But I'm not sure I like the idea of code like that going into redcar proper.

    What do you think about putting a redcar_support.rb file into the Snippets folders that need it? Then Redcar can require that when loading the Snippets and that'll define whatever needs to happen to make the snippets work in ruby land.
