SyntaxGrepHighlighter

Struct SyntaxGrepHighlighter 

Source
pub struct SyntaxGrepHighlighter { /* private fields */ }
Expand description

Per-language grammar cache backing the grep preview highlighter. None in the map means “this language has no registered grammar” — cached so repeated hits in an unsupported file don’t re-probe the registry. Wrapped in a Mutex because the trait is Sync and grep runs are serial within a task but may overlap across runs.

Implementations§

Source§

impl SyntaxGrepHighlighter

Source

pub fn new() -> Arc<Self> ⓘ

AH.1: takes no registry. It used to take the editor’s shared Arc<LangRegistry> “so grep previews highlight with exactly the grammars the buffers use” — which is what it stopped doing the moment plugin languages existed.

LangRegistry::standard() is registry::live(): it returns a SNAPSHOT of the process-global ArcSwap. A plugin’s grammar arrives later via install_plugin_config, which RCUs a new registry in and leaves every held Arc on the pre-plugin value. This highlighter was built at boot, so its registry was bundled-only forever — every preview of a .org hit (the org-roam node picker’s whole surface) painted plain.

Trait Implementations§

impl Default for SyntaxGrepHighlighter

Source§

fn default() -> Self

Returns the “default value” for a type. Read more

impl GrepPreviewHighlighter for SyntaxGrepHighlighter

Source§

fn highlight_line(&self, path: &Path, line: &str) -> Vec<DisplaySpan>

Highlight line as source for the file at path. line is the exact text shown as the candidate display (already trimmed), so returned spans are display-relative and need no offset. Empty result ⇒ plain preview.
