Item5215: Add unit test for deprecated definition list syntax.

When using a colon in a list item that spans multiple-lines, the colon will incorrectly force a line-break.

This code:

   * This is a list that will break%BR%
   Dates: 01/01/08 - 02/02/08

   * This is a list that will render correctly, as it doesn't have a colon.%BR%
   Dates 01/01/08 - 02/02/08

Creates:

• This is a list that will break
  

Dates

1/01/08 - 2/02/08

• This is a list that will render correctly, as it doesn't have a colon.
  Date 1/01/08 - 2/02/08

This behaviour isn't mentioned in TWiki:TWiki/TextFormattingRules, so I can only assume it's a bug.

This is actually an undocumented legacy feature. TWiki used to have this definition for definition lists: Three spaces, term, colon, space, defintion. Your example with "Date" matches that pattern.

See old syntax defined at http://twiki.org/cgi-bin/view/TWiki/TextFormattingRules?rev=51

We need to support legacy content (there are tens of millions of pages out there.)

Workaround: Add one or two more spaces before "date".

-- TWiki:Main.PeterThoeny - 06 Jan 2008

re-opening, as there are 3 spaces before the "date".

-- SvenDowideit - 07 Jan 2008

even presuming that we should continue to support this format, it would then need to be documented, and a unit test added.

So either way, it needs actioning.

-- TWiki:Main.SvenDowideit - 07 Jan 2008

• This is a list that will not break
  Dates: 01/01/08 - 02/02/08

This bug is about one space more or less, right? We have more than one problem with spaces in TWiki. IMHO this one doesn't classify as release blocker.

-- TWiki:Main.FranzJosefGigler - 07 Jan 2008

It is documented also in the current TextFormattingRules and clearly marked as deprecated syntax.

Adding a unit test. Noone will argue against that. Maybe it is already there? Like the doc. But it is for sure not a release blocker now we know that it is properly documented.

Changed the headline to the current nature of the bug.

-- TWiki:Main.KennethLavrsen - 07 Jan 2008

I came here to report this as a bug, but it seems that it's a known issue. However, contrary to Kenneth's claim that it's clearly documented and marked as deprecated does not appear to be the case at present (otherwise, I wouldn't be here trying to report it as a bug). The TextFormattingRules topic only state:

Three spaces, a dollar sign, the term, a colon, a space, followed by the definition.

I think that legacy support is fine, but it should be documented in TextFormattingRules.

-- MyqLarson - 03 Jan 201

Documentation has been updated, and a unit test added. I missed this for 1.1.7-RC2, but it will be in the final release.
