This is a short post on how to use backticks (` and ```) to quote code, so it is easy to read. This post can be linked to new users who are confused by this feature.
Why
By quoting your code, you get a monospaced font (which preserves indentation) and syntax highlighting. This makes it easier to read your code and help you.
Displayed code looks like this:
function displayed_code(x::Int, y::Int)
if x < y
println("x is smaller")
else
println("or not")
end
end
Inline code looks_like_this(c::Float64).
How
Discourse uses Markdown. The markdown specification uses triple backticks ``` to open and close displayed code blocks. A language can optionally be specified immediately after the opening ```. On this forum, the default language is julia.
```julia
function displayed_code(x::Int, y::Int)
if x < y
println("x is smaller")
else
println("or not")
end
end
```
The inline syntax uses single backticks: `looks_like_this(c::Float64)` (You can’t specify a language with inline code, so there is no syntax highlighting.)
Where
The backtick character (`) is located in the top left of the U.S. keyboard, above the Tab key.
It looks similar to but is different from the apostrophe character ('), sometimes also called a single quote.
On mobile, you will typically need to hold down the apostrophe key until a pop-up of similar characters appear for selection. Backtick is usually the option farthest to the left.
When
Always wrap code in backticks so it renders correctly and is distinguished from commentary. When writing your post, the preview window on the right side will show the formatted text. Check that the preview is formatted as you intended before posting.
That’s it! Please take advantage of this feature to make it easier to help you.

Quotes Contianing Backticks
If you want to quote backticks themselves, enclose them in more backticks: `` ` `` renders as `, and
````julia
"""
This is how you use this function:
```julia
1+1
```
"""
````
produces
"""
This is how you use this function:

which is useful when quoting code with docstrings that have ``` in them.
