Finally got emacs compilation-error-regexp working for perl CPAN Test::Unit::TestCase

Summary: Finally got emacs compilation-error-regexp working for perl CPAN Test::Unit::TestCase



Not only did I need to add a regexp,
but I also needed to disable a compilation-mode-font-lock-keywords pattern
- apparently there may be some phase ordering.

This woukd be more reliably if there were the ability to return ALL possible substrings matching a regexp,
as opposed to being maximally or minimally greedy.

    ;; adding patterns to compilation-error-regexp-alist and/or compilation-error-regexp-alist
    ;; to try to get a perl CPAN Test::Unit error message, like

    ;; There were 3 failures:
    ;; 1) TestCases_for_FrameMaker_MIF_AG.pm:875 - test_another_error(TestCases_for_AG_FrameMaker_MIF)
    ;; expected '', got 'deliberate mismatch'
    ;;
    ;; 2) TestCases_for_FrameMaker_MIF_AG.pm:879 - test_yet_another_error(TestCases_for_AG_FrameMaker_MIF)
    ;; expected '', got 'deliberate mismatch'
    ;;
    ;; 3) TestCases_for_FrameMaker_MIF_AG.pm:898 - test_special_stuff__format_tuple_to_MIF_string__Cell_context__WIP(TestCases_for_AG_FrameMaker_MIF)

    (require 'compile)

    (add-to-list 'compilation-error-regexp-alist
'("\nThere were [0-9]+ failures:\n1) \\([a-zA-Z0-9_.-.---]+\\):\\([0-9]+\\) - test_"

    (add-to-list 'compilation-error-regexp-alist
'("\n[0-9]+) \\([a-zA-Z0-9_.-.---]+\\):\\([0-9]+\\) - test_"
  1 2)
      )
    (if nil  ;; the regexp below causes compilation-error-regexp-alist to stop working completely - no matching
      (add-to-list 'compilation-error-regexp-alist
'("\nThere were [0-9]+ failures:\n1) .*\\(\\w\\|\\W)*\n[0-9]+) .*\\(test_\\)"
  2)
