How can I add JSON highlighting to the code in Jira comment?

Question

Is it possible to add a highlighted code to Jira comment? I want to write something like this:

---

The comment text and JSON doc:

{
  "key": 100
}

---

I've found only one example:

{code:javascript}
{
  "key": 100
}
{code}

But it does not really highlight my code. I see only the grey block.

Answer 1

You can try to add only {code} at the beginning and end of your code block.

Example:

{code}
{
  "key": 100
}
{code}

Answer 2

Recent Jira 7.5+ starts supporting more languages, including JSON.

Simply use:

{code:json}
...
{code}

See syntax highlighting in https://confluence.atlassian.com/jirasoftware/jira-software-7-5-x-release-notes-934719297.html#JIRASoftware7.5.xreleasenotes-tweaksMoreimprovements.

See documentation: https://jira.atlassian.com/secure/WikiRendererHelpAction.jspa?section=all

The default language is Java but you can specify others too, including ActionScript, Ada, AppleScript, bash, C, C#, C++, CSS, Erlang, Go, Groovy, Haskell, HTML, JavaScript, JSON, Lua, Nyan, Objc, Perl, PHP, Python, R, Ruby, Scala, SQL, Swift, VisualBasic, XML and YAML.

Default JIRA highlighting syntax list

If you have the syntax highlighting plugin you have more, but no JSON as per its homepage and this ticket asking for JSON-specific support.

Confluence doesn't have JSON-specific highlighting as per the Confluence formatting docs.
