I tried before to post a shell script that contained a ` character as an answer on Stack Overflow. The parser insisted on treating the backtick as formatting instead of part of code.
How can I include it?
If you do not want to use a pre-formatted block, there is still a way to do it inline.
To include a literal backtick character within a code span, you can use multiple backticks as the opening and closing delimiters:
``There is a literal backtick (`) here.``
The above example renders like this (double quotes added): “
There is a literal backtick (`) here.”
Also of note, you can add spaces to render an inline code segment that starts with and/or ends with backticks:
The backtick delimiters surrounding a code span may include spaces — one after the opening, one before the closing. This allows you to place literal backtick characters at the beginning or end of a code span:
A single backtick in a code span: `` ` `` A backtick-delimited string in a code span: `` `foo` ``
The above examples render like this (quotes added): “A single backtick in a code span:
`” and “A backtick-delimited string in a code span:
This may be implementation specific, but it looks like you can use N backticks to delimit any inline sequence that does not itself contain a maximal subsequence of exactly N backticks. For example, you can use three backticks to delimit a sequence that does not contain triple backticks (single, double, quadruple, quintuple, etc. are okay though).
Three quoting one, two and four: ``` one: ` two: `` four: ```` ``` Two quoting one, three, and four: `` one: ` three: ``` four: ```` `` One quoting two, three and four: ` two: `` three: ``` four: ```` `
Three quoting one, two and four:
one: ` two: `` four: ````
Two quoting one, three, and four:
one: ` three: ``` four: ````
One quoting two, three and four:
two: `` three: ``` four: ````
Finally, for comments:
Ah, in comments one does need to escape using a backslash? `\`yes\``.
ChrisF's solution is the cleanest and easiest method, so I recommend using that whenever you can.
But if you find yourself needing it for inline code text and can tolerate needing to use
<code> tags, its HTML entity
`, demonstrated here:
<code>this ` is a backtick</code> renders as
this ` is a backtick.
