# 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 commits to both manually.

# INFORMATION / HELP
#
# 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
