Wrap content with fence delimiters such as backticks (code blocks) or colons
(fenced Div). Optionally the fenced block can have attributes. The function
fenced_div() is a shorthand of fenced_block(char = ':').
fenced_block(x, attrs = NULL, fence = make_fence(x, char), char = "`")fenced_div(...)
make_fence(x, char = "`")
fenced_block() returns a character vector that contains both the
fences and content.
make_fence() returns a character string. If the block content
contains N fence characters (e.g., backticks), use N + 1 characters as
the fence.
A character vector of the block content.
A vector of block attributes.
The fence string, e.g., ::: or ```. This will be
generated from the char argument by default.
The fence character to be used to generate the fence string by default.
Arguments to be passed to fenced_block().
# code block with class 'r' and ID 'foo'
xfun::fenced_block("1+1", c(".r", "#foo"))
# fenced Div
xfun::fenced_block("This is a **Div**.", char = ":")
# three backticks by default
xfun::make_fence("1+1")
# needs five backticks for the fences because content has four
xfun::make_fence(c("````r", "1+1", "````"))
