[Caml-list] [ANN] Uucp 1.1.0

[Daniel Bünzli]

Hello,

It's my pleasure to announce the release of Uucp 1.1.0.

This release adds support for the East Asian width [1] character property which can be useful as an heuristic to perform layout of East-Asian text on devices with fixed-width character advances like terminals.

To that effect a *non-standard*, heuristic function Uucp.Break.tty_width_hint was contributed by David Kaloper. This function sums up all the practical knowledge he gathered about Unicode rendering in various terminals while developing his notty library [2].

Folding Uucp.Break.tty_width_hint [3] over the scalar values of a (preferably NFC) Unicode string can be used as an estimate of the number of columns it will occupy in a terminal. Given the non-homogenous state of tty Unicode rendering the function is not totally foolproof; it will at least work well with alphabetic scripts and some of the East Asian scripts, but your CHEESE WEDGE may vary. See the detailed documentation David wrote in [3] for more information on that unsolvable problem.

Uucp provides efficient access to a selection of character properties of the Unicode character database.
