-- compat.fribidi — the Unicode bidirectional algorithm.

--

-- THE GATE ON pango. Arabic and Hebrew text is stored in logical order and

-- drawn in visual order, and working out which run goes which way is UAX #9 —

-- a specified algorithm with a conformance test suite, not something a text

-- layout engine reimplements. pango's meson makes it a hard dependency, so

-- nothing above it renders right-to-left text without this.

--

-- ─────────────────────────────────────────────────────────────────────────

-- WHY AN INLINE DESCRIPTOR AND NOT A FORK

--

-- fribidi generates seven tables from the Unicode Character Database, with

-- eight C programs under `gen.tab/` that are compiled and RUN during a normal

-- build. That is exactly the shape that forced forks for libevdev, libxkbcommon

-- and libdisplay-info — except that the RELEASE TARBALL SHIPS THE OUTPUT:

--

-- lib/arabic-misc.tab.i lib/brackets-type.tab.i

-- lib/arabic-shaping.tab.i lib/joining-type.tab.i

-- lib/bidi-type.tab.i lib/mirroring.tab.i

-- lib/brackets.tab.i

-- lib/fribidi-unicode-version.h

--

-- Verified: the seven `#include "*.tab.i"` in `lib/*.c` are matched one for one

-- by files in the tarball, and `fribidi-unicode-version.h` — which meson also

-- generates — is there too. So there is nothing to generate and no fork to

-- justify. The criterion has always been "does something have to be RUN", and

-- here the answer is no.

--

-- Only `fribidi-config.h` is missing, because it is a `configure_file`

-- substitution rather than a generated table, and every value in it is a

-- property of this build. It is written out below.

--

-- ─────────────────────────────────────────────────────────────────────────

-- kind = "lib", NOT "shared"

--

-- Upstream ships libfribidi.so.0. Nothing dlopens it — pango links it at build

-- time — so merging the objects avoids a SONAME that would then have to coexist

-- with a distribution's copy. Same choice as freedesktop.libdisplay-info,

-- freedesktop.libevdev and wlroots, and for the same reason.
