Insert string `/empty/' between items.

* src/tools/docmaker/formatter.py (Formatter::section_dump): Make it
robust against nonexistent keys.

* src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit
empty <td> elements for `/empty/'.
2014-12-02 10:27:40 +01:00

ContentProcessor::finish): Replace `has_key' function with `in'
keyword.

Werner Lemberg 80bfeb1c3b [docmaker] Don't output a block multiple times.
This bug was hidden by not processing all lines of `<Order>' blocks.

* src/tools/docmaker/formatter.py (Formatter::section_dump): Filter
out field names.
2014-12-01 10:07:52 +01:00

Werner Lemberg 785b1d0892 [docmaker] Allow empty lines in `<Order>' blocks.
Before this patch, the suggested order of entries stopped at the
first empty line.

Obviously, nobody noticed that this problem caused a much reduced
set of links in the `Synopsis' sections; in particular, the
`<Order>' blocks contain a lot of entries that wouldn't be listed
otherwise...

* src/tools/docmaker/content.py (DocBlock::get_markup_words_all):
New function to iterate over all items.
(DocSection::process): Use it.

elements, use CSS descendants (of class `section') to format the
data.

Also remove reduntant <p> and <br> elements, replacing them with
proper CSS.

Globally reduce page width to 75%.

(block_header): Rename <div> class to `section'.
2014-11-29 20:08:29 +01:00

2014-11-27 19:28:48 +01:00
Werner Lemberg 26d699ed84 * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
For `Index' and `TOC' links, we now simply use the `text-align' CSS
property of `<td>' to enforce flush-left and flush-right,
eliminating the hack with an empty, full-width `<td>' element
inbetween.

The change also enforces the same (smaller) size for all index and
TOC links.

in a later patch.

Jarkko Pöyry 96341dc378 [cff, pfr, psaux, winfonts] Fix Savannah bug #43676.
Don't cast cmap init function pointers to an incompatible type.

Without this patch, the number of parameters between declaration and
the real signature differs.  Calling such a function results in
undefined behavior.

  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
    6.5.2.2 Function calls
      9 If the function is defined with a type that is not
        compatible with the type (of the expression) pointed to by
        the expression that denotes the called function, the
        behavior is undefined.

On certain platforms (c -> js with emscripten) this causes
termination of execution or invalid calls because in the emscripten
implementation, function pointers of different types are stored in
different pointer arrays.  Incorrect pointer type here results in
indexing of an incorrect array.

Alexei Podtelezhnikov f841ad3ec2 * src/base/fttrigon.c: Use dedicated `FT_Angle' for arctan table. 2014-11-19 21:19:06 -05:00
Werner Lemberg a67c43e1c8 Avoid compiler warnings on x86-64 for `FT_MulFix'.
`FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',
but several inline implementations of it in `ftcalc.h' take
`FT_Int32' arguments.  This is causing compiler warnings on x86-64:
If parameters of type `FT_Fixed' (= `FT_Long') are passed to the
inline implementation of this function, integer values are truncated
from 64bit to 32bit.

Werner Lemberg 706f752b5e * src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting.
Before this patch, it was impossible to ever call DELTAP[123] in
subpixel hinting mode as described in the ClearType whitepaper; it
only worked if in `compatibility mode'.  However, compatibility mode
essentially disables SHPIX, completely ruining hinting of
ttfautohint output, for example.

We now follow the whitepaper more closely so that DELTAP[123]
instructions for touched points in the non-subpixel direction are
executed.

Werner Lemberg 441b3f3898 [truetype] Improve handling of buggy `prep' tables.
In case of an error in the `prep' table, no longer try to execute it
again and again.  This makes FreeType handle endless loops in buggy
fonts much faster.

* src/truetype/ttobjs.h (TT_SizeRec): The fields `bytecode_ready'
and `cvt_ready' are now negative if not initialized yet, otherwise
they indicate the error code of the last run.

* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep,
tt_size_done_bytecode, tt_size_init_bytecode,
tt_size_ready_bytecode, tt_size_init, tt_size_done, tt_size_reset):
Updated.

* src/truetype/ttgload.c (tt_loader_init): Updated.
* src/truetype/ttinterp.c (TT_RunIns): Force reexecution of `fpgm'
and `prep' only if we are in the `glyf' table.
