In order to support RTL/BIDI, wezterm needs a bidi implementation. I don't think a well-conforming rust implementation exists today; what I found were implementations that didn't pass 100% of the conformance tests. So I decided to port "bidiref", the reference implementation of the UBA described in http://unicode.org/reports/tr9/ to Rust. This implementation focuses on conformance: no special measures have been taken to optimize it so far, with my focus having been to ensure that all of the approx 780,000 test cases in the unicode data for unicode 14 pass. Having the tests passing 100% allows for making performance improvements with confidence in the future. The API isn't completely designed/fully baked. Until I get to hooking it up to wezterm's shaper, I'm not 100% sure exactly what I'll need. There's a good discussion on API in https://github.com/open-i18n/rust-unic/issues/273 that suggests omitting "legacy" operations such as reordering. I suspect that wezterm may actually need that function to support monospace text layout in some terminal scenarios, but regardless: reordering is part of the conformance test suite so it remains a part of the API. That said: the API does model the major operations as separate phases, so you should be able to pay for just what you use: * Resolving the embedding levels from a paragraph * Returning paragraph runs of those levels (and their directions) * Returning the whitespace-level-reset runs for a line-slice within the paragraph * Returning the reordered indices + levels for a line-slice within the paragraph. refs: https://github.com/wez/wezterm/issues/784 refs: https://github.com/kas-gui/kas-text/issues/20
