<div dir="ltr">I think I've mislead you, I didn't mean to use the documentation of that library :) I think old harfbuzz had some of the things you've mentioned like justification.<div><br></div><div>Anyways, I guess <a href="https://mail.gnome.org/archives/gtk-i18n-list/2009-August/msg00025.html">this link</a> would be more useful as some of basic (probably you know them already) but expected to be used more APIs are described there at least.</div><div><br></div><div>Another perhaps interesting way to measure usage of an API and understand its use is to inspect other clients, specially the big ones like Chromium/Google Chrome which should handles many edge cases. For example, "hb_font_get_glyph_advance_for_direction" is not used once even on Chromium <a href="https://cs.chromium.org/search/?q=hb_font_get_glyph_advance_for_direction&sq=package:chromium&type=cs">once even</a> which roughly means it is not of a canonical API for the library and hb_font_get_glyph is used <a href="https://cs.chromium.org/chromium/src/third_party/WebKit/Source/platform/fonts/FontPlatformData.cpp?q=hb_font_get_glyph&sq=package:chromium&dr=C&l=282">here</a> which checks if a font has a special glyph for space so is it possible to use caching word shaping strategy (in here, if a font contains space glyph it means the strategy should be turned off but for the majority of fonts it is not the case), very special strategy not used by every client of harfbuzz and the API also doesn't seem to be essential for most of clients.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jun 27, 2016 at 4:36 AM, Kelvin Ma <span dir="ltr"><<a href="mailto:kelvinsthirteen@gmail.com" target="_blank">kelvinsthirteen@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Well this is the first time I’ve used a shaper, and also the first time
