Syntax highlighting demo
Demonstrating syntax highlighting in Quarto with various languages.
Syntax highlighting theme can be set in YAML as highlight-style
with either the name of a KDE style (see KSyntaxHighlighting color themes), or as a valid JSON file with extension .theme
. For details on KDE color-theme files, see “The Color Themes JSON Format” (Working with Color Themes, KDE Documentation).
See Quarto’s options for code chunks for HTML output for more information on styling code chunks.
R example
# plotting of R objects
<- function (x, y, ...)
plot
{if (is.function(x) &&
is.null(attr(x, "class")))
{if (missing(y))
<- NULL
y
# check for ylab argument
<- function(...)
hasylab !all(is.na(
pmatch(names(list(...)),
"ylab")))
if (hasylab(...))
plot.function(x, y, ...)
else
plot.function(
x, y, ylab = paste(
deparse(substitute(x)),
"(x)"),
...)
}else
UseMethod("plot")
}
Python example
@requires_authorization(roles=["ADMIN"])
def somefunc(param1='', param2=0):
r'''A docstring'''
if param1 > param2: # interesting
print 'Gre\'ater'
return (param2 - param1 + 1 + 0b10l) or None
class SomeClass:
pass
>>> message = '''interpreter
... prompt'''
JavaScript example
const pluckDeep = key => obj => key.split('.').reduce((accum, key) => accum[key], obj)
const compose = (...fns) => res => fns.reduce((accum, next) => next(accum), res)
const unfold = (f, seed) => {
const go = (f, seed, acc) => {
const res = f(seed)
return res ? go(f, res[1], acc.concat([res[0]])) : acc
}return go(f, seed, [])
}
SCSS example
/*-- scss:defaults --*/
$h2-font-size: 1.6rem !default;
$headings-font-weight: 500 !default;
$body-color: $gray-700 !default;
/*-- scss:rules --*/
, h2, h3, h4, h5, h6 {
h1text-shadow: -1px -1px 0 rgba(0, 0, 0, .3);
}
