Implementations

impl CommonMarkCache

pub fn clear_scrollable(&mut self)

Clear the cache for all scrollable elements

pub fn clear_scrollable_with_id(&mut self, source_id: impl Hash) -> bool

Clear the cache for a specific scrollable viewer. Returns false if the id was not in the cache.

pub fn add_link_hook<S: Into<String>>(&mut self, name: S)

If the user clicks on a link in the markdown render that has name as a link. The hook specified with this method will be set to true. It’s status can be acquired with get_link_hook. Be aware that all hook state is reset once [CommonMarkViewer::show] gets called

Why use link hooks

egui provides a method for checking links afterwards so why use this instead?

ctx.output_mut(|o| o.open_url.is_some());

The main difference is that link hooks allows egui_commonmark to check for link hooks while rendering. Normally when hovering over a link, egui_commonmark will display the full url. With link hooks this feature is disabled, but to do that all hooks must be known.

pub fn remove_link_hook(&mut self, name: &str) -> Option<bool>

Returns None if the link hook could not be found. Returns the last known status of the hook otherwise.

pub fn get_link_hook(&self, name: &str) -> Option<bool>

Get status of link. Returns true if it was clicked

pub fn link_hooks_clear(&mut self)

Remove all link hooks

pub fn link_hooks(&self) -> &HashMap<String, bool>

All link hooks

pub fn link_hooks_mut(&mut self) -> &mut HashMap<String, bool>

Raw access to link hooks
