A simple GIR parser in Swift for creating Swift types for a .gir file
To build, you need at least Swift 4.2 (Swift 5.x 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 5.0.1 (swiftlang-1001.0.82.4 clang-1001.0.46.5) Target: x86_64-apple-darwin18.6.0
on macOS, or on Linux you should get something like:
$ swift --version Swift version 5.0.1 (swift-5.0.1-RELEASE) Target: x86_64-unknown-linux-gnu
LibXML 2.9.4 or higher
These Swift wrappers have been tested with libxml-2.9.4 and 2.9.9. They should work with higher versions, but YMMV. Also make sure you have
gobject-introspection and its
.gir files installed.
On current versions of macOS, you need to install
libxml2 using HomeBrew (the version that comes with the system does not include the necessary development headers -- for HomeBrew setup instructions, see http://brew.sh):
brew update brew install libxml2 gobject-introspection
On Ubuntu 16.04 and 18.04, you can use the gtk that comes with the distribution. Just install with the
apt package manager:
sudo apt update sudo apt install libxml2-dev gobject-introspection libgirepository1.0-dev
On Fedora 29, you can use the gtk that comes with the distribution. Just install with the
dnf package manager:
sudo dnf install libxml2-devel gobject-introspection-devel
Normally, you don't build this package directly, but you embed it into your own project (see 'Embedding' below). 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/gir2swift.git cd gir2swift ./build.sh
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 gir2swift.xcodeproj
After that, use the (usual) Build and Test buttons to build/test this package.
Here are some common errors you might encounter and how to fix them.
Old Swift toolchain or Xcode
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 (Swift 5.0.1 at the time of this writing) 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
