Markdown Table formatting breaks with redmine wiki links
0%
Description
When formatting a table in markdown, and inserting internal wiki links via [[wiki_page_name|custom name]], such as:
| header | [[FAQ]] | [[Plugins|List of Plugins]] | |--------|---------|-----------------------------| | aaa | bbb | ccc |
The [[Plugins|List of Plugins]] will get incorrectly truncated at | which is interpreted as signaling the end of that column, and hence the URL link is not generated as it breaks off before reaching the ]].

FWIW, in the meantime, the following workaround is available:
Instead of [[wiki_page_name|custom name]] one can write [custom name](wiki_page_name).
Updating the above table example:
| header | [[FAQ]] | [List of Plugins](Plugins) | |--------|---------|----------------------------| | aaa | bbb | ccc |
Disclaimer: I don't know if this workaround would work for cross-project-wiki references...

FYI - This problem remains in latest redmine v3.4.2 (and its updated redcarpet gem)
In redmine 3.3.x and 3.4.x, it renders as such:
Could this problem be due to redcarpet gem itself, vs. redmine's integration of redcarpet..?

I confirmed that redcarpet gem cannot distinguish '|'.
To solve this problem, It is necessary to replace '|', before and after redcarpet is formatting Markdown to HTML.
So, I made a patch that overrides Redcarpet::Render::HTML#preprocess and #postprocess methods and replace '|'.

Thanks Takenori for the patch. I've found out that the regexp does not work when it is trying to replace the | placeholder back with |, as the placeholder is multicharacter and used in a character class.
As a result, it does not work if the name contains e.g. numbers 1, 2 or 4.
The solution is to use this regexp:
full_document.gsub(/(\[\[(((?![\]\n]|#{pattern}).)+)(#{pattern})(((?![\]\n]|#{pattern}).)+)\]\])/) do |m|
all, page, separater, title = $1, $2, $4, $5
A new patch is attached (it's against Redmine 3.4 though).
