A Swift wrapper around pango-1.x that is largely auto-generated from gobject-introspection. For up to date (auto-generated) reference documentation, see https://rhx.github.io/SwiftPango/
Version 12 of gir2swift pulls in PR#10, addressing several issues:
-aoption generates all records
Version 11 introduces a new type system into
to ensure it has a representation of the underlying types.
This is necessary for Swift 5.3 onwards, which requires more stringent casts.
As a consequence, accessors can accept and return idiomatic Swift rather than
underlying types or pointers.
This means that a lot of the changes will be source-breaking for code that
was compiled against libraries built with earlier versions of
@inlinableto enable the compiler to optimise away most of the wrappers
Refwrappers instead of pointers,
ErrorTypehas been renamed
GLibErrorto ensure it neither clashes with
Refwrapper instead of the underlying pointer
To build, you need at least Swift 5.2 (Swift 5.3+ should work fine), download from https://swift.org/download/ -- if you are using macOS, make sure you have the command line tools installed as well). Test that your compiler works using
swift --version, which should give you something like
$ swift --version Apple Swift version 5.4 (swiftlang-1220.127.116.11 clang-118.104.22.168) Target: x86_64-apple-darwin20.5.0
on macOS, or on Linux you should get something like:
$ swift --version Swift version 5.4 (swift-5.4-RELEASE) Target: x86_64-unknown-linux-gnu
These Swift wrappers have been tested with pango-1.40, 1.42, 1.44, and 1.46 as well as glib-2.56, 2.58, 2.60, 2.62, 2.64, 2.66, and 2.68. They should work with higher versions, but YMMV. Also make sure you have
gobject-introspection and its
.gir files installed.
On Ubuntu 18.04 and 20.04, you can use the gtk that comes with the distribution. Just install with the
apt package manager:
sudo apt update sudo apt install libpango1.0-dev gir1.2-pango-1.0 gobject-introspection libgirepository1.0-dev libxml2-dev
On Fedora 29, you can use the gtk that comes with the distribution. Just install with the
dnf package manager:
sudo dnf install pango-devel glib2-devel gobject-introspection-devel libxml2-devel
On macOS, you can install glib and Cairo using HomeBrew (for setup instructions, see http://brew.sh). Once you have a running HomeBrew installation, you can use it to install a native version of cairo:
brew update brew install pango glib glib-networking gobject-introspection pkg-config
Normally, you don't build this package directly (but for testing you can - see 'Building' below). Instead you need to embed SwiftPango into your own project using the Swift Package Manager. After installing the prerequisites (see 'Prerequisites' below), add
SwiftPango as a dependency to your
Package.swift file, e.g.:
// swift-tools-version:5.3 import PackageDescription let package = Package(name: "MyPackage", dependencies: [ .package(name: "gir2swift", url: "https://github.com/rhx/gir2swift.git", .branch("main")), .package(name: "Pango", url: "https://github.com/rhx/SwiftPango.git", .branch("main")), ], targets: [.target(name: "MyPackage", dependencies: ["Pango"])] )
Normally, you don't build this package directly, but you embed it into your own project (see 'Usage' above). However, you can build and test this module separately to ensure that everything works. Make sure you have all the prerequisites installed (see above). After that, you can simply clone this repository and build the command line executable (be patient, this will download all the required dependencies and take a while to compile) using
git clone https://github.com/rhx/SwiftPango.git cd SwiftPango ./run-gir2swift.sh swift build swift test
Please note that on macOS, due to a bug in the Swift Package Manager prior to Swift 5.4,
if you have Xcode-12.4 or older, you need to pass in the build flags manually,
i.e. instead of
swift build and
swift test you can run
swift build `./run-gir2swift.sh flags -noUpdate` swift test `./run-gir2swift.sh flags -noUpdate`
On macOS, you can build the project using Xcode instead. To do this, you need to create an Xcode project first, then open the project in the Xcode IDE:
./xcodegen.sh open Pango.xcodeproj
After that, use the (usual) Build and Test buttons to build/test this package.
You can find reference documentation inside the docs folder.
This was generated using the jazzy tool.
If you want to generate your own documentation, matching your local installation,
you can use the
generate-documentation.sh script in the repository.
Unfortunately, at this stage jazzy only works on macOS (and crashes under Linux), so this will currently only work on a Mac.
Here are some common errors you might encounter and how to fix them.
If you get an error such as
$ ./build.sh error: unable to invoke subcommand: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-package (No such file or directory)
this probably means that your Swift toolchain is too old. Make sure the latest toolchain is the one that is found when you run the Swift compiler (see above).
If you get an older version, make sure that the right version of the swift compiler is found first in your
PATH. On macOS, use xcode-select to select and install the latest version, e.g.:
sudo xcode-select -s /Applications/Xcode.app xcode-select --install
When building, a lot of warnings appear. This is largely an issue with automatic
RawRepresentable conformance in the Swift Standard library. As a workaround, you can turn this off by passing the
-Xswiftc -suppress-warnings parameter when building.
The current build system does not support directory paths with spaces (e.g. the
My Drive directory used by Google Drive File Stream).
BUILD_DIR is not supported in the current build system.
As a workaround, you can use the old build scripts, e.g.
./build.sh (instead of
swift build) to build a package.
