bindbc-glib 1.0.0
Static & dynamic bindings to GLib & GObject, compatible with BetterC, @nogc, and nothrow.
To use this package, run the following command in your project's root directory:
Manual usage
Put the following dependency into your project's dependences section:
BindBC-GLib
This project provides a set of both static and dynamic bindings to GLib & GObject. They are compatible with @nogc
and nothrow
, and can be compiled with BetterC compatibility.

License
BindBC-GLib—as well as every other binding in the BindBC project—is licensed under the Boost Software License.
Bear in mind that you still need to abide by GLib's license if you use it through these bindings.
GLib documentation
This readme describes how to use BindBC-GLib, not GLib and GObject themselves. BindBC-GLib does have minor API changes from GLib and GObject, which are listed in Binding-specific changes. Otherwise BindBC-GLib is a direct D binding to the GLib & GObject C APIs, so any existing GLib/GObject documentation and tutorials can be adapted with only minor modifications.
Quickstart guide
To use BindBC-GLib in your dub project, add it and BindBC-GLib to the list of dependencies
in your dub configuration file. The easiest way is by running dub add bindbc-glib
in your project folder. The result should look something like this:
Example dub.json
"dependencies": {
"bindbc-glib": "~>1.0",
},
Example dub.sdl
dependency "bindbc-glib" version="~>1.0"
If you want to use the GObject bindings, you'll have to add the :gobject
submodule as a dependency:
Example dub.json
"dependencies": {
"bindbc-glib": "~>1.0",
"bindbc-glib:gobject": "~>1.0",
},
Example dub.sdl
dependency "bindbc-glib" version="~>1.0"
dependency "bindbc-glib:gobject" version="~>1.0"
By default, BindBC-GLib is configured to compile as a dynamic binding that is not BetterC-compatible. If you prefer static bindings or need BetterC compatibility, they can be enabled via subConfigurations
in your dub configuration file. For configuration naming & more details, see Configurations.
Example dub.json
"subConfigurations": {
"bindbc-glib": "staticBC",
},
Example dub.sdl
subConfiguration "bindbc-glib" "staticBC"
If you need to use versions of GLib & GObject newer than 2.2.0, then you will have to add the appropriate version identifier to versions
in your dub configuration. For a list of library version identifiers, see Library versions.
If you're using static bindings, then you will also need to add the name of the GLib library (and the GObject library if you're using it) to libs
.
Example dub.json
"versions": [
"GLib_2_40_0",
],
"libs": [
"glib-2.0", "gobject-2.0",
],
Example dub.sdl
versions "GLib_2_40_0"
libs "glib-2.0" "gobject-2.0"
If you're using static bindings: import bindbc.glib
in your code, and then you can use all of GLib just like you would in C. That's it!
import bindbc.glib;
void main(){
auto heapInt = cast(int*)g_malloc0(int.sizeof);
//etc.
g_free(heapInt);
}
If you're using dynamic bindings: you need to load each library you need with the appropriate load function. loadGLib
for GLib, and loadGObject
for GObject.
For most use cases, it's best to use BindBC-Loader's error handling API to see if there were any errors while loading the library. This information can be written to a log file before aborting the program.
The load function will also return a member of the LoadMsg
enum, which can be used for debugging:
noLibrary
means the library couldn't be found.badLibrary
means there was an error while loading the library.success
means that the library was loaded without any errors.
Here's a simple example using only the load function's return value:
import bindbc.glib;
import bindbc.loader;
/*
This code attempts to load the GLib shared library using
well-known variations of the library name for the host system.
*/
LoadMsg ret = loadGLib();
if(ret != LoadMsg.success){
/*
Error handling. For most use cases, it's best to use the error handling API in
BindBC-Loader to retrieve error messages for logging and then abort.
If necessary, it's possible to determine the root cause via the return value:
*/
if(ret == LoadMsg.noLibrary){
//The GLib shared library failed to load
}else if(ret == LoadMsg.badLibrary){
//One or more symbols failed to load.
}
}
/*
This code attempts to load GLib using a user-supplied file name.
Usually, the name and/or path used will be platform specific, as in this
example which attempts to load `glib.dll` from the `libs` subdirectory,
relative to the executable, only on Windows.
*/
version(Windows) loadGLib("libs/glib.dll");
The error handling API in BindBC-Loader can be used to log error messages:
import bindbc.glib;
/*
Import the sharedlib module for error handling. Assigning an alias ensures that the
function names do not conflict with other public APIs. This isn't strictly necessary,
but the API names are common enough that they could appear in other packages.
*/
import loader = bindbc.loader.sharedlib;
bool loadLib(){
LoadMsg ret = loadGLib();
if(ret != LoadMsg.success){
//Log the error info
foreach(info; loader.errors){
/*
A hypothetical logging function. Note that `info.error` and
`info.message` are `const(char)*`, not `string`.
*/
logError(info.error, info.message);
}
//Optionally construct a user-friendly error message for the user
string msg;
if(ret == LoadMsg.noLibrary){
msg = "This application requires the GLib library.";
}else{
if(auto versionMsg = glib_check_version(glibVersion.major, glibVersion.minor, glibVersion.patch)){
msg = versionMsg;
}else{
msg = "There should be a version mismatch, but there isn't. Submit an issue to BindBC-GLib.";
}
}
//A hypothetical message box function
showMessageBox(msg);
return false;
}
return true;
}
Binding-specific changes
Features that have been deprecated since the creation of these bindings are omitted. Some modules have also been omitted for simplicity (e.g. modules with atomics, multi-threading, time, and dates). If you need any of these features, please create a PR or open an issue.
Complex code-generation #defines
have been converted to string mixin generators. Most cases where identifiers are passed in C are string parameters instead:
mixin(G_DEFINE_TYPE("GStringSubclass", "gstring_subclass", "G_TYPE_GSTRING"));
Enums are available both in their original C-style UPPER_SNAKE_CASE
form, and as the D-style PascalCase.camelCase
. Both variants are enabled by default, but can be selectively chosen using the version identifiers GLib_C_Enums_Only
or GLib_D_Enums_Only
respectively.
[!NOTE]\ The version identifiers
BindBC_C_Enums_Only
andBindBC_D_Enums_Only
can be used to configure all of the applicable official BindBC packages used in your program. Package-specific version identifiers override this.
camelCase
d variants are available for struct fields using snake_case
or lowercase
.
Configurations
BindBC-GLib has the following configurations:
┌ | DRuntime | BetterC |
---|---|---|
Dynamic | dynamic | dynamicBC |
Static | static | staticBC |
For projects that don't use dub, if BindBC-GLib is compiled for static bindings then the version identifier BindGLib_Static
must be passed to your compiler when building your project.
[!NOTE]\ The version identifier
BindBC_Static
can be used to configure all of the official BindBC packages used in your program. (i.e. those maintained in the BindBC GitHub organisation) Some third-party BindBC packages may support it as well.
Dynamic bindings
The dynamic bindings have no link-time dependency on GLib, so the GLib shared library must be manually loaded at runtime from the shared library search path of the user's system. On Windows, this is typically handled by distributing the GLib DLLs with your program. On other systems, it usually means installing the GLib shared library through a package manager.
The function isGLibLoaded
returns true
if any version of the shared library has been loaded and false
if not. unloadGLib
can be used to unload a successfully loaded shared library.
Static bindings
Static bindings do not require static linking. The static bindings have a link-time dependency on either the shared or static GLib library. On Windows, you can link with the static library or, to use the DLLs, the import library. On other systems, you can link with either the static library or directly with the shared library.
When linking with the shared (or import) library, there is a runtime dependency on the shared library just as there is when using the dynamic bindings. The difference is that the shared library are no longer loaded manually—loading is handled automatically by the system when the program is launched. Attempting to call loadGLib
with the static bindings enabled will result in a compilation error.
Static linking requires GLib's development packages be installed on your system. The GLib repository provides the library's source code. You can also install them via your system's package manager. For example, on Debian-based Linux distributions sudo apt install libglib2.0-dev
will install both the development and runtime packages for GLib.
When linking with the static library, there is no runtime dependency on GLib.
