[util] Better file-not-found error from hb-shape / hb-view 
fixes #1266
 2018-10-18 07:38:47 +03:30
Behdad Esfahbod 1e8fdd285f Remove HAVE_OT 
We never tested compiling without it.  Just kill it.  We always build
our own shaper.

Behdad Esfahbod e42cd58c99 Rename invisible_codepoint to invisible_glyph in API 
Deleted recently added API:
    hb_buffer_set_invisible_codepoint()
    hb_buffer_get_invisible_codepoint()

    hb-shape / hb-view --invisible-codepoint

New API:
    hb_buffer_set_invisible_glyph()
    hb_buffer_get_invisible_glyph()

    hb-shape / hb-view --invisible-glyph

Fixes https://github.com/harfbuzz/harfbuzz/issues/1216

Behdad Esfahbod 9caa432d0c [util] Use HB_FALLTHROUGH 
Sure, gcc knows to warn about this as well:

../../util/options.cc:175:17: warning: this statement may fall through [-Wimplicit-fallthrough=]
     case 1: m.r = m.t;
             ~~~~^~~~~
../../util/options.cc:176:5: note: here
     case 2: m.b = m.t;
     ^~~~

But HOLY SMOKES, look at clang -Weverything bot message:

options.cc:176:5: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough]
    case 2: m.b = m.t;
    ^
options.cc:176:5: note: insert 'HB_FALLTHROUGH;' to silence this warning
    case 2: m.b = m.t;
    ^
    HB_FALLTHROUGH;

Right, it's telling me to insert "HB_FALLTHROUGH;" there!!!!!!!!!

Behdad Esfahbod 2e728a7d86 [util] Mark var static

Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert() 
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

Revert file blob sanitization and index checking (#1062) 
As https://github.com/harfbuzz/harfbuzz/pull/1059#issuecomment-397912812 we
like to still work with blobs that harfbuzz itself can't handle directly that are failing sanitization
currently apparently.

Ebrahim Byagowi c53697d3f2
Verbose fail when something is wrong with hb-shape/hb-view input font file (#1059) 
This checks if the blob isn't empty and uses `hb_face_count`
to see if the font file passes the simple font file sanitization
so can detect if the input is actually a font and checks also
whether input font-index is out of range.

Ebrahim Byagowi aa0c5df419
Fix reading fonts from stdin (#1060) 
We were passing the font path directly to freetype so rendering
was broken when we are getting the font from stdin.

This fixes it by using FT_New_Memory_Face instead.

This fixes:
* build/util/hb-view /dev/stdin text < font.ttf
* build/util/hb-view - text < font.ttf
* cat font.ttf | build/util/hb-view - text

but doesn't work on
* cat font.ttf | build/util/hb-view /dev/stdin text

which I will try to fix separately.

Behdad Esfahbod e60350551a [hb-shape] Improve shaping-debug output 
Before, that was printed using --debug (and in both hb-shape and hb-view).
Changed it, now hb-shape has a new command-line argument called --show-messages.
When invoked, it also respects other output formatting options.  The messages
are better formatted and printed to te same place that hb-shape output is
directed to.  Previously they were written to stderr.
