# Macros for Qt6 packages

#
####################################################################
# Provides the following macros:
#
# %%cmake_qt6
#   Runs CMake using the default paths for Qt6 packages
#
# %%qt6_build
#   Builds the project with the selected build tool
#
# %%qt6_install
#   Installs the project once built
#
# %%qt6_use_make
#   Use 'make' instead of 'ninja' for building
#
#   Alternatively, you can add the following line in your spec file:
#   %%global %%__qt6_build_tool make
#
# %%qt6_build_docs
#   Build the documentation for the package
#
# %%qt6_install_docs
#   Install the generated documentation
#
# %%qt6_doc_packages
#   Creates documentation packages.
#   When using this macro, two subpackages will be defined for
#   qch and html docs.
#
# See below for details about documentation packages
#
# %%qt6_examples_package
#   If the package you're building contains examples, this macro
#   will create a -examples subpackages and handle the installed
#   files.
#
# %%qt6_link_executables
#   Executables are installed in %%{_qt6_bindir}.
#   To avoid conflicts with older versions, symlinks are created
#   in %%{_bindir} with the '6' suffix.
#   You may call this macro in your %install section to create the
#   links.
#
# %%qmake6
#   Configure a project using qmake
#
# %%qmake6_build
#   Builds a project configured using the %%qmake6 macro
#
# %%qmake6_install
#   Installs a project configured using the %%qmake6 macro

# Notes about documentation packages:
#
# There are different ways to create documentation packages.
#
# NOTE: all methods described below need a 'BuildRequires: qt6-tools'
# line.
#
# Method #1: Build flavors (recommended)
#   The build service allows building different packages with a
#   single spec file.
#
#   Create a _multibuild file containing:
#       <multibuild>
#         <flavor>docs</flavor>
#       </multibuild>
#
#   Add this to the spec file header, add:
#
#       %global qt6_flavor @BUILD_FLAVOR@%{nil}
#
#   The following code shall be added after the other build requirements:
#
#       %if "%qt6_flavor" == "docs"
#       BuildRequires:  qt6-tools
#       %{qt6_doc_packages}
#       %endif
#
#   This will ensure the 'qt6-tools' package is installed for building
#   documentation and also define and populate the two documentation
#   subpackages.
#
#   Two commands are available to disable parts of the spec file that are
#   not needed when building the 'docs' flavor:
#       %if %{qt6_docs_flavor}  : true if the docs flavor is built
#       %if !%{qt6_docs_flavor} : true if the docs flavor is not built
#       (note the position of the '!' sign)
#
#   They shall be used to ignore: 
#     - non-docs packages descriptions
#     - post-install actions
#     - %files sections
#
#
# Method #2: doc subpackage
#   Create a spec file for the documentation package.
#   The %%qt6_doc_packages macro will create the %%package and
#   %%files sections for both the QCH and HTML documentation
#   packages.
#
#   The %%qt6_build_docs and %%qt6_install_docs macros will
#   respectively replace the %%qt6_build and %%qt6_install
#   invokations.
#
#   When using a documentation subpackage, it is recommended to copy
#   the 'BuildRequires' and '%%bcond' lines from the main package
#   spec file.
#
#   Example:
#   In qt6-svg-docs.spec, use %%qt6_doc_packages, %%qt6_build_docs
#   and %%qt6_install_docs.
#   2 subpackages will be defined (qt6-svg-docs-html and qt6-svg-docs-qch)
#   and the respective %files sections will be populated automatically.
