Werner Lemberg fcdab61ed1 [build] Use gcc (and clang) in C99 mode.
Other compilers are unchanged.

* builds/compiler/gcc-dev.mk, builds/compiler/gcc.mk (ANSIFLAGS):
s/-ansi/-std=c99/.

* builds/freetype.mk (FT_CFLAGS): Remove `-std=c99`.

* builds/unix/configure.raw: Handle C99.
Remove no longer needed test for gcc 4.6 and earlier.

Werner Lemberg 1c229af2d2 [dlg] Fix compiler warnings.
* src/dlg/dlgwrap.c: Duplicate some feature test macros from
`dlg.c`, which must come first before loading standard headers.  For
example, `freetype.h` loads `stdio.h` if compiled in debug mode.

Werner Lemberg ce43d808dc [base] Implement vertical alignment of log printing.
Based on a patch by Priyesh.

* include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH):
New macro.

* src/base/ftdebug.c, builds/windows/ftdebug.c (ft_log_handler):
Print logs after a fixed width to handle different lengths of
`FT_COMPONENT` entries.
Use `ft_strrchr` to check for final newline character.

Priyesh Kumar 6d9e6b21e5 * src/*: Fix `-Wformat` warnings. 2020-12-04 16:19:42 +01:00
Priyesh Kumar 2a5d8e8ff8 [builds/windows] Changes to build 'dlg' with FreeType on Windows.
We only support Visual C++ 2010 and newer.

* builds/windows/vc2010/script.bat: New windows batch file to copy
necessary 'dlg' files from `submodules/dlg` to `src/dlg`.  This file
is used as a pre-built event in Visual C++.

* builds/windows/ftdebug.c: Synchronize with `src/base/ftdebug.c`.

* builds/windows/vc2010/freetype.vcxproj.filters: Add
`src/dlgwrap.c`.

* builds/windows/vc2010/freetype.vcxproj
(AdditionalIncludeDirectories): Add include files of dlg for 'Debug'
and 'Debug Static' configurations on both 'x64' and 'win32'
platforms.
(PreprocessorDefinitions): Add `FT_LOGGING` for 'Debug' and 'Debug
Static' configurations on both 'x64' and 'win32' platforms.
Add `DLG_STATIC' for 'Debug' configuration on 'x64' and 'win32'
platforms.
(DisableLanguageExtensions): We need to disable the `/Za` option
when building 'dlg' with FreeType as 'dlg' strictly follows the C99
standard.  Visual C++ produces behaves unexpectedly when
compiling a C99 file with `/Za` option enabled.
2020-12-04 16:19:42 +01:00

* src/base/ftdebug.c (FT_Set_Log_Handler,
FT_Set_Default_Log_Handler, FT_Logging_Callback): Add function
definitions.
2020-12-04 16:19:36 +01:00

FT_LOGGING_TAG_): New macros to resolve the value of `FT_COMPONENT'
into a string.

necessary source and include files from `submodules/dlg` to
`src/dlg`.

(OBJ_S, OBJ_M): Add `DLG_OBJS_M` and `DLG_OBJS_S`.

* builds/toplevel.mk: For builds directly from the git repository
we need to copy files from `submodule/dlg` to `src/dlg`.

* include/freetype/config/ftoption.h, devel/ftoption.h (FT_LOGGING):
New macro to enable or disable the logging facility in FreeType.

Werner Lemberg c9f588be56 Document changes to last release. 2020-10-10 12:48:18 +02:00
Werner Lemberg 40479fad93 [autofit] Synchronize with ttfautohint.
This corresponds to the following commits in the ttfautohint git
repository:

  bb6842bd3bd437b7b4a7921b0376c860f5e73d18  Typo, formatting.
  d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa  Add Medefaidrin script.

* src/autofit/afblue.dat: Add blue zone data for Medefaidrin.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

* src/autofit/afscript.h: Add Medefaidrin standard characters.

* src/autofit/afranges.c, src/autofit/afstyles.h: Add Medefaidrin
data.
2020-09-25 17:44:00 +02:00
Werner Lemberg e8ee98e669 Move `scripts/make_distribution_archives.py` to `src/tools`.
* scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR,
_SCRIPT_DIR): Updated to new location.
(main): s/shutils.copyfile/shutils.copy/ to preserve file
permissions.
(main): Prefix source file paths with `git_dir` while copying files
to allow calls of the script from other places than the top-level
directory.
2020-09-25 08:07:43 +02:00
Werner Lemberg 4f13a43ab3 * src/cff/cffgload.c (cff_slot_load): Scale `vertBearingY`.
Towards the end of the the function there is a call to
`FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units.
That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY`
is left alone, and is not scaled.

Patch from Eric Muller <emuller@amazon.com>.
2020-09-24 09:35:24 +02:00
Werner Lemberg bed960d948 * src/base/ftobjs.c (FT_Load_Glyph): Trace glyph metrics. 2020-09-24 09:31:56 +02:00
Werner Lemberg 3ce0df52e2 [meson] Move auxiliary scripts to `builds/meson`.
Suggested by Alexei.

* scripts/*.py: Move meson scripts to...
* builds/meson/*.py: ... this new location.

* meson.build: Updated.
2020-09-22 20:05:37 +02:00
David Turner d686f2ff9c Add python script for building tarballs.
* scripts/make_distribution_archives.py: New file.

This standalone Python script should be equivalent to running `make
dist` with the Make-based build system, with the following minor
differences:

- Since `make distclean` doesn't always clean up `objs/` properly,
  `make dist` archives may contain some stale binaries like
  `objs/.libs/libfreetype.so.6` or others.

- `config.guess` and `config.sub` are not updated unless option
  `--gnu-config-dir=DIR` is used to specify the location of these
  files.

- Some bits of the auto-generated reference documentation may
  appear in slightly different order, probably due to issues related
  to mkdocs and docwriter.

As an example, the call

  scripts/make_distribution_archives.py /tmp/freetype2-dist

creates the following files under `/tmp/freetype2-dist`:

  freetype-<version>.tar.gz
  freetype-<version>.tar.xz
  ft<winversion>.zip
2020-09-21 09:27:51 +02:00
Werner Lemberg 46417607e6 * scripts/extract_freetype_version.py: Fix regex typos. 2020-09-21 09:21:46 +02:00
David Turner 66978a5887 Add Meson build project file.
Example usage:

  # Configure Meson build in directory `build-meson` to generate
  # release binaries comparable to to the ones from the
  # autotools/make build system.
  meson setup build-meson \
        --prefix=/usr/local \
        --buildtype=debugoptimized \
        --strip \
        -Db_ndebug=true

  # After configuring the Meson build with the above command,
  # compile and install to `/usr/local/`; this includes a pkg-config
  # file.
  ninja -C build-meson install

  # Alternatively, compile and install to `/tmp/aa/usr/local/...`
  # for packaging.
  DESTDIR=/tmp/aa ninja -C build-meson install

  # Generate documentation under `build-meson/docs`.
  ninja -C build-meson docs

Library size comparison for stripped `libfreetype.so` generated by
all three build systems:

  - Default build (autotools + libtool): 712 KiB
  - CMake build (RelWithDebInfo):        712 KiB
  - Meson build:                         712 KiB

* meson.build: New top-level Meson build file for the library.

* meson_options.txt: New file.  It holds user-selectable options for
the build, which can be printed with `meson configure`, and selected
at `meson setup` or `meson --reconfigure` time with
`-D<option>=<value>`.

* scripts/parse_modules_cfg.py: A script invoked by `meson.build` to
parse `modules.cfg` and extract important information out of it
(i.e., the list of modules).

* scripts/process_ftoption_h.py: New script invoked by `meson.build`
to process the original `ftoption.h` file.  It enables or disables
configuration macro variables based on the available dependencies.
This is similar to what other build systems are using (i.e., Meson's
`configure_file()` command is not used here).

* scripts/extract_freetype_version.py: New script invoked by
`meson.build` to extract the FreeType version number from
`<freetype/freetype.h>`.

* scripts/extract_libtool_version.py: New script invoked by
`meson.build` to extract the libtool `revision_info` data from
`builds/unix/configure.raw`, and to generate the corresponding
shared library suffix.

* scripts/generate_reference_docs.py: New script invoked by
`meson.build` to generate the FreeType 2 reference documentation
(using the `docwriter` and `mkdocs` packages, which must be already
installed).
