Overview ¶
Package code converts between byte offsets and the line/column coordinates AnchorDB stores in bindings.
Lines are 1-based. Columns are 1-based *rune* offsets within their line, not byte offsets. Producers that natively work in bytes -- tree-sitter, for one -- must convert through PositionIndex before writing a span, otherwise any line containing non-ASCII text yields a column that Slice cannot resolve.

Functions ¶
func Context ¶
Context returns the `window` lines immediately before startLine and immediately after endLine. Line numbers outside the content are clamped, so a stale binding pointing past the end of a shrunken file yields empty context instead of panicking.
Types ¶
type PositionIndex ¶
type PositionIndex struct {
// contains filtered or unexported fields
}
PositionIndex converts byte offsets in a fixed piece of content into the line/rune-column coordinates described in the package docs. Building it once per file keeps conversion cheap when a file yields many symbols.
func NewPositionIndex ¶
func NewPositionIndex(content string) *PositionIndex
