Bug: Incorrect Whitespace Parsing in ToC

In a Table Of Contents, some formatting commands are only parsed correctly if a non-whitespace character is entered between the heading command ---+ and the formatting command.

Test case

this should be strong and in a code font

. but only if not the first non whitespace character

same for any rendering code?

nope, some codes, like strong emphasis are ignored in either case

*how* about *double strong* ?

Yup, *double strong* works, so there are actually two bugs here

Incorrect Whitespace Parsing in ToC, and:

Emphasis Ignored in Headings

Environment

here on Twiki.org

Hmm, may be a correct fix would be to remove all formatting from the TOC bullets? Opinions?

I "vote" against that -- formatting (TWiki markup) should work wherever it is applied.

This brings to mind another point -- when an inline search is used to display the page name (topic) and summary, TWiki markup within the summary is not formatted. I believe it should be. If you need an example, I can create (or find) one.

Is anybody working on this? I sure would like to see it fixed (and I don't have the time to work on it). An example of the problem I have is visible at http://twiki.ntp.org - look at the TOC for 5.4 (I think).

Fix record

I vote to keep formatting in TOC, too.

I fixed this bug. Formatting for bold and italic have already been filtered out. For consistency I added the filtering of fixed text as well. This fixes the bug. This bug happens only if you have fixed text at the very beginning or end of a heading.

BTW, **double strong** is not valid TWiki syntax and is not supported.

Fix in TWikiAlphaRelease and at TWiki.org. Fix you can easly apply to your installation:
