Open Source Common Lisp Libraries

STMX is a high-performance Common Lisp library for composable Transactional Memory (TM), a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions: if a memory transaction returns normally it gets committed, if instead it signals an error (Lisp slang for throwing an exception) it is rolled back. Memory transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and effects of a transaction are not visible from other threads until it commits. STMX gives freedom from deadlocks, automatic rollback on failure, and it aims at resolving the tension between granularity and concurrency.

Backwards mappable double linked list for Common Lisp.

The CLAST library provides parsing, AST manipulation and "walking" for Common Lisp code.

alien-sdl contains SDL foreign function interface bindings for SBCL.

Binary file format provides interface for Common Lisp to read and write binary files in a simple way.

cl-bmp is a simple library to read BMP files. The library is implemented in Common Lisp.

B-Tree implemented in Common Lisp. Stores key/value pairs onto disk based data structure. Current implementation has been tested with SBCL. Project was originally at alien-consader.org but is now made available at SourceForge.

Swap file is a fixed block size storage library implemented in Common Lisp.

Toolbox contains a few common utilities used in other projects. Toolbox has also for example a generic non-trivial double-linked list implementation which uses SBCL's weak-pointers when referencing to previous item.

cl-wal is a simple write ahead log library implemented in Common Lisp. Write ahead log writes entries first to a journal and then to master stream.

Highly automated Common Lisp bindings for GTK+ v2.x by Espen S. Johnsen. The CLG library uses GLib introspection feature to build the binding system. This fork incorporates the fixes to run the system on the stable version of Debian Linux distribution.

Takes care of all needed repetitive low-level initialization and allows you to quickly create the following types of sockets: * TCP server * TCP client * UDP unicast producer * UDP unicast consumer * UDP multicast producer * UDP multicast consumer * CAN socket (Linux only) CLI programs: * broadcast-hear - tests for incoming unicast/multicast traffic; * broadcast-roar - continuously sends user-specified unicast/multicast messages; * recast - converts unicast to multicast (and vice-versa) packets; * cancom - communicate over CAN bus (generate/send/receive messages, ping other nodes).
