how to allow html tag in redmine wiki
Added by Tuan-Tu Tran almost 6 years ago
Hello,
My wiki settings are such that it uses Markdown (and not Textile) formatting.
My goal here is to be able to color text.
I found in the user guide for markdown formatting
that html tags must be allowed for this to work:
Note: HTML tags need to be allowed to use the HTML tag (<span>). See #15520-16 and #15520-17 for details.
I went over the linked issues but I only saw warnings on why this should not be done for security reasons.
I have to admit I did not read the entire issues.
At the top of the user guide it also says:
Currently HTML tags are not allowed by default. See #15520 and #20497 for details. For other limitations of the current Markdown formatting see #16373 and #21443.
But I can't find how to allow HTML tags.
Is there a configuration/setting for this ?
Or does the code need to be patched e.g. https://www.redmine.org/projects/redmine/repository/revisions/14449/entry/trunk/lib/redmine/wiki_formatting/markdown/formatter.rb#L122
Thanks in advance for your help.

You may use macro html
this way:
{{html your html content }}Example
before html {{html <b>this is bold</b> <i>this is italic</i> This is normal }}after html
The macro should be inserted in <path_to_redmine>/lib/redmine/wiki_formatting/macros.rb
somewhere among other macros there:
desc "Insert html" + "\n\n" +
" !{{html\n<HTML CODE HERE>\n}}"
macro :html do |obj, args, text|
text.html_safe
end
Don't forget to restart Redmine.

Hello
Thank you for your answer.
However I was hoping for something more integrated with the markdown, as described here in the user documentation:
https://www.redmine.org/projects/redmine/wiki/RedmineTextFormattingMarkdown#Color
with an html macro as you proposed, I guess I'd have to do things like:
{{html <ul> <li> <span style="color:red">red</span> <span style="color:green">green</span> </li> <li> ... </li> </ul> }}
to achieve the same list, which is much less convenient.
The note in the user documentation
Note: HTML tags need to be allowed to use the HTML tag (<span>). See #15520-16 and #15520-17 for details.
suggests there's a straightforward way to just allow the HTML tag <span>
I just can't seem to find it and that was more the object of my initial question.
Thanks again.

Hi!
You can change it here
redmine/lib/redmine/wiki_formatting/markdown/formatter.rb
I changed the boolean from true to false for filter_html
def formatter @@formatter ||= Redcarpet::Markdown.new( Redmine::WikiFormatting::Markdown::HTML.new( :filter_html => false, :hard_wrap => true ), :autolink => true, :fenced_code_blocks => true, :space_after_headers => true, :tables => true, :strikethrough => true, :superscript => true, :no_intra_emphasis => true, :footnotes => true, :lax_spacing => true, :underline => true ) end
Then restart redmine

Thanks.
I've updated the documentation accordingly:
https://www.redmine.org/projects/redmine/wiki/RedmineTextFormattingMarkdown/diff?utf8=%E2%9C%93&version=26&version_from=24&commit=View+differences
Now that I re-read this, it was indeed pointed out in #15520#note-16 but it was not very explicit:
For the Markdown implementation see source:/trunk/lib/redmine/wiki_formatting/markdown/formatter.rb@14449#L122, which tells the Redcarpet gem to filter out any HTML from the user input completely.

Can someone please also post a solution for the "CommonMark Markdown (Github Flavored) - experimental" formatter.
The mentioned file looks completely different and I am lost at to what needs to be changed. Thank you!
(I'm switching from Textile to Markdown and from what I gathered the new "CommonMark Markdown" will eventually become the default Markdown "flavour" for Redmine. So I want to directly use it instead of the current "default" Markdown.)
