MingaEditor.RenderModel.Window.GuideIndex (Minga v0.1.0)

Persistent index of nonblank resident rows and their raw indent levels.

Lazy suffix shifts make structural edits logarithmic. Blank-row guide continuity is represented as compressed ranges resolved from the next nonblank row, so edits never walk a long blank suffix.

Summary

Types

t()

tree_node()

Functions

affected_bounds(index, start_row, insert_count)

Returns the smallest final half-open range whose blank continuity can change at a splice.

all_runs(index)

build(entries, tab_width)

max_level(guide_index)

runs(guide_index, start_row, end_row)

Returns compressed resolved guide levels for a half-open row range.

splice(index, start_row, delete_count, inserted, tab_width)

Applies one immutable-base row splice and returns the updated index.

work(guide_index, start_row, end_row)

Types

t()
