eventcore 0.9.31
Pro-actor based abstraction layer over operating system asynchronous I/O facilities.
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:
EventCore
This is a high-performance native event loop abstraction for D, focused on asynchronous I/O and GUI message integration. The API is callback (delegate) based. For a higher level fiber based abstraction, take a look at vibe.d.
The API documentation is part of vibe.d:

Compile-time configuration
Configurations
The DUB configuration meachnism can be used to force choosing a particular event driver implementation. The following configurations are available:
EventcoreCFRunLoopDriver
: Forces using the CFRunLoop driver (for DUB, use the "cfrunloop" configuration instead)
EventcoreKqueueDriver
: Forces using the kqueue driver (for DUB, use the "kqueue" configuration instead)
EventcoreWinAPIDriver
: Forces using the WinAPI driver (for DUB, use the "winapi" configuration instead)
EventcoreLibasyncDriver
: Forces using the libasync driver (for DUB, use the "libasync" configuration instead)
EventcoreSelectDriver
: Forces using the select driver (for DUB, use the "select" configuration instead)
EventcoreUseGAIA
: Forces using getaddressinfo_a for the epoll driver (for DUB, use the "epoll-gaia" configuration instead)
Version identifiers
Several version identifiers can be set to configure the behavior of the library at compile time. Simply insert any of the following identifiers as a "version" to the compiler command line or into your DUB recipe:
dub.sdl:
versions "EventCoreSilenceLeakWarnings"
dub.json:
{
...
"versions": ["EventCoreSilenceLeakWarnings"]
...
}
EventCoreSilenceLeakWarnings
: Disables checking for leaked handles at shutdownEventcoreCFRunLoopDriver
: Forces using the CFRunLoop driver (for DUB, use the "cfrunloop" configuration instead)EventcoreKqueueDriver
: Forces using the kqueue driver (for DUB, use the "kqueue" configuration instead)EventcoreWinAPIDriver
: Forces using the WinAPI driver (for DUB, use the "winapi" configuration instead)EventcoreLibasyncDriver
: Forces using the libasync driver (for DUB, use the "libasync" configuration instead)EventcoreSelectDriver
: Forces using the select driver (for DUB, use the "select" configuration instead)EventcoreUseGAIA
: Forces using getaddressinfo_a for the epoll driver (for DUB, use the "epoll-gaia" configuration instead)
Debug identifiers
For additional debug output, the following debug identifiers are available. When
building with DUB, you can specify them similar to version identifiers, but using
the debugVersions
directive instead:
EventCoreLogDNS
: Prints detailed information about DNS lookupsEventCoreLeakTrace
: Gathers stack traces when allocating handles to assist in fixing leaked handlesEventCoreEpollDebug
: Outputs epoll event detailsEventCoreLogFiles
: Outputs detailed logging for file operations carried out through thethreadedfile
