MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.

Recent releases


Release Notes: This release fixes a couple of bugs.


Release Notes: This version contains a number of small fixes. The Arg() methods in the String class are now less error-prone. Short-circuit logic in the QueryFilters was improved. The DefaultConsoleLogger and DefaultFileLogger classes were exposed for re-use elsewhere. .pro files were updated for compatibility with Qt 5.0.


Release Notes: This release adds some additional functionality to the included hexterm utility, and merges in some Haiku compatibility tweaks. It also tweaks the address matching so that IPv4 addresses are matched using IPv4 syntax.


Release Notes: Minor bugs were fixed. Memory usage of the Message class was reduced a bit, better control over the zlib-encoding of outgoing compressed Message objects was provided, and a deprecated Queue method was removed (GetItemPointer()).


Release Notes: This version adds a couple of gateway subclasses that keep track of the number of bytes currently in their output queues, adds a couple of additional callbacks to the ReflectServer class, and fixes a couple of minor bugs.

You need to add QueryFilter.o and ByteBuffer.o to the Makefile to get it to compile with latest MUSCLE's.

Confusing name
The name of this project is rather confusing. MUSCLE is already the name of the de-facto standard smartcard environment for Linux. (Google for "muscle linux" and you'll see what I mean.)
