ticket wiki formatting error

[chris.alex.thomas@…]

I just created a ticket in my installation and I found this error.

I wanted to imput the text

bl:description[[br]]
rm:description[[br]]

and the wiki formatter for some reason doesnt like this and failed to process the [[br]] as line breaks, and basically the text I put into the ticket change history, output in the wiki page when it reloaded, also, the line break didnt occur either.

so I think that some types of text combinations can cause the wiki to be confused.

is it possible to just turn off the wiki processing completely and just store the raw text, cause most of the time, I don't care about it and sometimes it just gets in my way when I don't want fancy markup, I just want a raw text entry box to type into.

This specific misformat is because it thinks the [] are part of a TracLink with the prefix bl: or rm:, respectively. The simple way around this is add a space between the bl:description and the [[br]] which will cause TracLink parsing to cease, then detect the macro correctly.

One way of fixing this that I can stand behind is to specialcase [[ as not allowed in the middle of TracLinks.

sounds like a better plan than reformatting my text to fix the wiki parser.

doing

bl: description[[br]]

is not the same and well, I am sure you agree, making me sidestep the wiki parsers bugs aint a good solutions.

thanks, hope this fix reaches 10.3 :D

[Noah Kantrowitz <coderanger@…>]

I think suggestion was:

bl:description [[br]]
rm:description [[br]]

[chris.alex.thomas@…]

ahhhhh, I see, ok, well thats better, but still, his fix takes care of that and the other case where you don't have a space if I understood his fix correctly.

Well, as we don't allow "]" in a SHREF, we probably could forbid use of "[" as well.

If such a character is really needed, one can always use the quoting,
as in wiki:"description[[br]]"?

[Tim Hatch <trac@…>]

Where does it say ] is not allowed in SHREF? I think mine allows it... ​http://asd]asd

[ is used for PHP forms that have multiselect boxes, so I think a single one (not a pair) should be allowed. Something like ...?var[1]=on&var[2]=on is quite normal.

[cboos]

I was talking about the regexp for wiki:asd]asd?, but obviously I was also wrong in that case ;)

So it's only for [wiki:asd]asd] where it's currently not possible to have that (asd?asd]), as the first ] seen will close the so-called LHREF link.

[cboos]

Well, I don't see what's left to do with this ticket...

For people not wanting WikiFormatting, there's the code block:

{{{

}}}

which can even be inserted from the wiki "tool bar".

For using [ and ] in links (comment:6), there are alternative syntaxes:
<http://asd]asd> (<​http://asd]asd>) and [[http://asd]asd]] (​http://asd]asd) (soon, #4356).
