Member Function Documentation

analyze()

BidiParagraph pulp::canvas::BidiAnalyzer::analyze ( std::string_view text, BidiBaseDirection base_direction = BidiBaseDirection::Auto )

static

Analyze one paragraph of UTF-8 text.

base_direction selects the paragraph level (Auto = UBA rule P2). Always returns a non-empty runs vector when text is non-empty.

has_sheenbidi()

bool pulp::canvas::BidiAnalyzer::has_sheenbidi ( )

staticnoexcept

True when the build links SheenBidi.

Tests that need the real engine (vs the pass-through stub) gate themselves on this.

visual_order()

std::vector< BidiRun > pulp::canvas::BidiAnalyzer::visual_order ( const std::vector< BidiRun > & runs )

static

Re-order runs (in logical order, as returned by analyze) into visual / paint order via UBA rules L1-L2.

The implementation is a simplified L2 reverse-on-odd-level pass — sufficient for single-line label paint. TextEditor's multi-line wrap path stays on the SkShaper / ICU iterator route in text_run_planner.cpp.
