Struct FindPattern 

pub struct FindPattern { /* private fields */ }

A compiled find pattern, plus the case decision that produced it.

Implementations

impl FindPattern

pub fn compile(query: &str) -> Result<Self, Error>

Compile query under smartcase: an all-lowercase query matches any case, any uppercase makes it exact.

The (?i) is prepended rather than set via RegexBuilder so a user-written inline flag ((?-i), or a scoped (?i:…)) still wins — later inline flags override earlier ones.

pub fn as_regex(&self) -> &Regex

pub fn case_sensitive(&self) -> bool

pub fn has_captures(&self) -> bool

pub fn count_matches<S: AsRef<str>>( &self, rows: impl Iterator<Item = S>, ) -> usize

Total matches across every line. Cheap enough to run per keystroke: this is find_iter over strings the editor already holds, not the cell-by-cell row reconstruction that paint_viewport_extras avoids.

pub fn match_spans<S: AsRef<str>>( &self, rows: impl Iterator<Item = S>, ) -> Vec<(usize, usize, usize)>

Every match as a (row, start_char, end_char) span in logical buffer coordinates.

The same coordinates count_matches and the textarea’s stepping use, so highlighting built from these cannot disagree with them about what matched — the way matching against rendered cell text does the moment a row contains concealed markdown.

pub fn expand(&self, caps: &Captures<'_>, replacement: &str) -> String

Expand replacement for one match.

Capture syntax ($1, ${name}) is honoured only when the pattern captures. Otherwise the replacement is literal, so a $ in ordinary note content — a price, inline LaTeX — survives instead of silently expanding to the empty string.

Even when the pattern captures, a $ that names a group which does not exist stays literal. Captures::expand would erase it: in a note $100 parses as group 100 and $x^2$ as a group named x, and both expand to nothing. Gating on whether the pattern captures at all is not enough — a user who writes a capture group is exactly the user who then writes $1 costs $100.
