Embeddable Common Lisp

<p>Embeddable Common Lisp (ECL) is a small implementation of the <a href="/facts/ANSI/p3d1TQCb">ANSI</a> <a href="/facts/Common_Lisp/mq1pRbSF">Common Lisp</a> <a href="/facts/Programming_language/cWTYbgWa">programming language</a> that can be used stand-alone or embedded in extant applications written in <a href="/facts/C_(programming_language)/Ky2No763">C</a>. It creates OS-native <a href="/facts/Executable/VSst9eLA">executables</a> and libraries (i.e. <a href="/facts/Executable_and_Linkable_Format/ro2CYqso">Executable and Linkable Format</a> (ELF) files on unix) from Common Lisp code, and runs on most platforms that support a C <a href="/facts/Compiler/WNfCDFJe">compiler</a>. The ECL runtime is a dynamically loadable library for use by applications. It is distributed as <a href="/facts/Free_software/IaoVtJXn">free software</a> under a <a href="/facts/GNU_Lesser_Public_License/AXwkz9x3">GNU Lesser Public License</a> (LGPL) 2.1+.
</p><p>It includes a <a href="/facts/Runtime_system/YmCuC4xP">runtime system</a>, and two <a href="/facts/Compiler/WNfCDFJe">compilers</a>, a <a href="/facts/Bytecode/EPkMFR7M">bytecode</a> interpreter allowing applications to be deployed where no C compiler is expected, and an <a href="/facts/Intermediate_representation/s0qRrbfh">intermediate language</a> type, which compiles Common Lisp to C for a more efficient runtime. The latter also features a native <a href="/facts/Foreign_function_interface/ntAxkhK0">foreign function interface</a> (FFI), that supports inline C as part of Common Lisp. Inline C FFI combined with Common Lisp macros, custom Lisp setf expansions and compiler-macros, result in a custom compile-time C <a href="/facts/Preprocessor/arTRL5RG">preprocessor</a>.
