Code block render hook.
|
|
Wraps Hugo's standard syntax-highlighted output in a container with a
|
copy-to-clipboard button. Highlighting still honours the site's
|
[markup.highlight] configuration because we delegate to
|
transform.HighlightCodeBlock, which reads both the per-fence options and the
|
global config.
|
|
Progressive enhancement: the button is rendered with the `hidden` attribute
|
and is only revealed by site-scripts.html when JavaScript runs, so sites
|
without JS show no inert button. The copy behaviour itself is wired by the
|
same script (a single delegated listener).
|
|
Disable site-wide with `[ananke] copy_code = false` (see params.toml).
