+# Freetype2 CI
+ 
+Continuous integration is a tool used in software development to ensure that
+ your application and/or library builds and runs correctly. 
+ Continuous deployment takes this a step further and uses the builds from 
+ the CI to create releases for developers and other users to download and 
+ use. In this folder are several configuration files and scripts drafted by
+ Greg Williamson for a 2020 GSoC 
+ project: https://summerofcode.withgoogle.com/projects/#5724074732421120
+ 
+# How it works
+ 
+Upon each commit, several builds are triggered for various operating systems 
+ and build configurations. Each build status is then reported back to the 
+ developers in the Pull Request comment section on GitLab or GitHub. Each 
+ build creates artifacts containing the newly-built FreeType libraries for 
+ developers and users to download. There are also special pipeline phases 
+ called "Regression Tests" that run FreeType's built-in demo programs to 
+ compare visual outputs between commits. An HTML report that contains a 
+ table of the results is uploaded as an artifact for these tests. For text 
+ output there is an HTML page displaying a .diff generated and for images a 
+ special page is generated that shows both images, layered, so that you can 
+ mouse over each to see differences. There is also a generated heatmap image 
+ which will draw matching regions of the image in green, and any mismatching 
+ regions in red.
+ 
+# Running locally
+ 
+All of the "Regression Tests" can be run locally (Currently only on 
+ Linux-based platforms). You will need to have xvfb, imagemagick, and 
+ prettydiff installed. You can find more details about this in 
+ CI/ft-regression.sh. You will also need "Liberation Fonts" which can be 
+ found here: https://releases.pagure.org/liberation-fonts/. The current 
+ tests expect the .ttf files to be extracted to ${HOME}/test-fonts. Once set
+ up, you can run all tests by running ./CI/ft-regression.sh <TEST_INDEX>, 
+ where TEST_INDEX is the index of the test you wish to run (or "all" to run 
+ all tests). Run this command from inside the directory you cloned FreeType 
+ to. An HTML report will then be generated to /tmp/ft-test for you to 
+ inspect.
+ 
+# Adding / Changing Tests
+ 
+All regular build tests are listed and configured in azure-pipelines.yml and
+ the several templates it includes in the CI/ folder. If you wish to add an 
+ additional platform or build configuration, azure-pipelines.yml is the place 
+ to do so. For "Regression Tests", there exists a configuration file at 
+ CI/ft-tests.config that contains an array where you can add, remove or change
+ test configurations. Each line in the array is a separate test. In order to 
+ have Azure run new tests, you will also need to modify azure-pipelines.yml 
+ at the root of the project to add/remove tests from the matrix. For each 
+ test, you will need to add a line to the yaml like so:
+ 
+```yaml
+  strategy:
+    matrix:
+      Test1:
+        TEST: 0
+      Test2:
+        TEST: 1
+      Test3:
+        TEST: 2
+```
+ 
+# Todo
+ 
+Savannah doesn't allow for integration with any modern CI so this cannot be 
+ implemented directly until FreeType moves to GitLab or GitHub. GitHub makes 
+ integrating this as simple as a few mouse clicks. For the GitLab route, 
+ however, we may need to port my yaml configurations to their CI's format. 
+ Another alternative is mirroring the repo. GitLab does have some mirroring 
+ capabilities, but for Savannah, developers would need to upload their commit
+ to both manually.

-FREETYPE LICENSES
-----------------
-
-The FreeType  2 font  engine is  copyrighted work  and cannot  be used
-legally without  a software  license.  In order  to make  this project
-usable to  a vast majority of  developers, we distribute it  under two
-mutually exclusive open-source licenses.
-
-This means that *you* must choose  *one* of the two licenses described
-below, then obey all its terms and conditions when using FreeType 2 in
-any of your projects or products.
-
-  - The FreeType License,  found in the file  `docs/FTL.TXT`, which is
-    similar to the  original BSD license *with*  an advertising clause
-    that forces  you to explicitly  cite the FreeType project  in your
-    product's  documentation.  All  details are  in the  license file.
-    This license is suited to products which don't use the GNU General
-    Public License.
-
-    Note that  this license  is compatible to  the GNU  General Public
-    License version 3, but not version 2.
-
-  - The   GNU   General   Public   License   version   2,   found   in
-    `docs/GPLv2.TXT`  (any  later  version  can  be  used  also),  for
-    programs  which  already  use  the  GPL.  Note  that  the  FTL  is
-    incompatible with GPLv2 due to its advertisement clause.
-
-The contributed  BDF and PCF  drivers come  with a license  similar to
-that  of the  X Window  System.   It is  compatible to  the above  two
-licenses (see files `src/bdf/README`  and `src/pcf/README`).  The same
-holds   for   the   source    code   files   `src/base/fthash.c`   and
-`include/freetype/internal/fthash.h`; they wer part  of the BDF driver
-in earlier FreeType versions.
-
-The gzip  module uses the  zlib license (see  `src/gzip/zlib.h`) which
-too is compatible to the above two licenses.
-
-The  MD5 checksum  support  (only used  for  debugging in  development
-builds) is in the public domain.

+# The following arguments control the behaviour of this toolchain:
+#
+# PLATFORM: (default "OS")
+#    OS = Build for iPhoneOS.
+#    OS64 = Build for arm64 iphoneOS.
+#    OS64COMBINED = Build for arm64 x86_64 iphoneOS. Combined into FAT STATIC lib (supported on 3.14+ of CMakewith "-G Xcode" argument ONLY)
+#    SIMULATOR = Build for x86 i386 iphoneOS Simulator.
+#    SIMULATOR64 = Build for x86_64 iphoneOS Simulator.
+#    TVOS = Build for arm64 tvOS.
+#    TVOSCOMBINED = Build for arm64 x86_64 tvOS. Combined into FAT STATIC lib (supported on 3.14+ of CMake with "-G Xcode" argument ONLY)
+#    SIMULATOR_TVOS = Build for x86_64 tvOS Simulator.
+#    WATCHOS = Build for armv7k arm64_32 for watchOS.
+#    WATCHOSCOMBINED = Build for armv7k arm64_32 x86_64 watchOS. Combined into FAT STATIC lib (supported on 3.14+ of CMake with "-G Xcode" argument ONLY)
+#    SIMULATOR_WATCHOS = Build for x86_64 for watchOS Simulator.
+#
+# CMAKE_OSX_SYSROOT: Path to the SDK to use.  By default this is
+#    automatically determined from PLATFORM and xcodebuild, but
+#    can also be manually specified (although this should not be required).
+#
+# CMAKE_DEVELOPER_ROOT: Path to the Developer directory for the platform
+#    being compiled for.  By default this is automatically determined from
+#    CMAKE_OSX_SYSROOT, but can also be manually specified (although this should
+#    not be required).
+#
+# DEPLOYMENT_TARGET: Minimum SDK version to target. Default 2.0 on watchOS and 9.0 on tvOS+iOS
+#
+# ENABLE_BITCODE: (1|0) Enables or disables bitcode support. Default 1 (true)
+#
+# ENABLE_ARC: (1|0) Enables or disables ARC support. Default 1 (true, ARC enabled by default)
+#
+# ENABLE_VISIBILITY: (1|0) Enables or disables symbol visibility support. Default 0 (false, visibility hidden by default)
+#
+# ENABLE_STRICT_TRY_COMPILE: (1|0) Enables or disables strict try_compile() on all Check* directives (will run linker
+#    to actually check if linking is possible). Default 0 (false, will set CMAKE_TRY_COMPILE_TARGET_TYPE to STATIC_LIBRARY)
+#
+# ARCHS: (armv7 armv7s armv7k arm64 arm64_32 i386 x86_64) If specified, will override the default architectures for the given PLATFORM
+#    OS = armv7 armv7s arm64 (if applicable)
+#    OS64 = arm64 (if applicable)
+#    SIMULATOR = i386
+#    SIMULATOR64 = x86_64
+#    TVOS = arm64
+#    SIMULATOR_TVOS = x86_64 (i386 has since long been deprecated)
+#    WATCHOS = armv7k arm64_32 (if applicable)
+#    SIMULATOR_WATCHOS = x86_64 (i386 has since long been deprecated)
+#
+# This toolchain defines the following variables for use externally:
+#
+# XCODE_VERSION: Version number (not including Build version) of Xcode detected.
+# SDK_VERSION: Version of SDK being used.
+# CMAKE_OSX_ARCHITECTURES: Architectures being compiled for (generated from PLATFORM).
+# APPLE_TARGET_TRIPLE: Used by autoconf build systems. NOTE: If "ARCHS" are overridden, this will *NOT* be set!
+#
+# This toolchain defines the following macros for use externally:
+#
+# set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE XCODE_VARIANT)
+#   A convenience macro for setting xcode specific properties on targets.
+#   Available variants are: All, Release, RelWithDebInfo, Debug, MinSizeRel
+#   example: set_xcode_property (myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1" "all").
+#
+# find_host_package (PROGRAM ARGS)
+#   A macro used to find executable programs on the host system, not within the
+#   environment.  Thanks to the android-cmake project for providing the
+#   command.

-# Options
-# -------
-#
-#   IOS_PLATFORM = OS | SIMULATOR
-#
-#     This decides whether SDKS are selected from the `iPhoneOS.platform' or
-#     `iPhoneSimulator.platform' folders.
-#
-#     OS - the default, used to build for iPhone and iPad physical devices,
-#       which have an ARM architecture.
-#     SIMULATOR - used to build for the Simulator platforms, which have an
-#       x86 architecture.
-#
-#   CMAKE_IOS_DEVELOPER_ROOT = /path/to/platform/Developer folder
-#
-#     By default, this location is automatically chosen based on the
-#     IOS_PLATFORM value above.  If you manually set this variable, it
-#     overrides the default location and forces the use of a particular
-#     Developer Platform.
-#
-#   CMAKE_IOS_SDK_ROOT = /path/to/platform/Developer/SDKs/SDK folder
-#
-#     By default, this location is automatically chosen based on the
-#     CMAKE_IOS_DEVELOPER_ROOT value.  In this case it is always the most
-#     up-to-date SDK found in the CMAKE_IOS_DEVELOPER_ROOT path.  If you
-#     manually set this variable, it forces the use of a specific SDK
-#     version.
-#
-#
-# Macros
-# ------
-#
-#   set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE)
-#
-#     A convenience macro for setting Xcode specific properties on targets.
-#
-#     Example:
-#
-#       set_xcode_property(myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1")
-#
-#   find_host_package (PROGRAM ARGS)
-#
-#     A macro to find executable programs on the host system, not within the

-# SYNOPSIS
-#
-#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
-#
-# DESCRIPTION
-#
-#   This macro figures out how to build C programs using POSIX threads. It
-#   sets the PTHREAD_LIBS output variable to the threads library and linker
-#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
-#   flags that are needed. (The user can also force certain compiler
-#   flags/libs to be tested by setting these environment variables.)
-#
-#   Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is
-#   needed for multi-threaded programs (defaults to the value of CC
-#   respectively CXX otherwise). (This is necessary on e.g. AIX to use the
-#   special cc_r/CC_r compiler alias.)
-#
-#   NOTE: You are assumed to not only compile your program with these flags,
-#   but also to link with them as well. For example, you might link with
-#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
-#   $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
-#
-#   If you are only building threaded programs, you may wish to use these
-#   variables in your default LIBS, CFLAGS, and CC:
-#
-#     LIBS="$PTHREAD_LIBS $LIBS"
-#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-#     CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS"
-#     CC="$PTHREAD_CC"
-#     CXX="$PTHREAD_CXX"
-#
-#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
-#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
-#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-#
-#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
-#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
-#   PTHREAD_CFLAGS.
-#
-#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
-#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
-#   is not found. If ACTION-IF-FOUND is not specified, the default action
-#   will define HAVE_PTHREAD.
-#
-#   Please let the authors know if this macro fails on any platform, or if
-#   you have any other suggestions or comments. This macro was based on work
-#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
-#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
-#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
-#   grateful for the helpful feedback of numerous users.
