A source-to-source translator, source-to-source compiler (S2S compiler), transcompiler, or transpiler [1] [2] [3] is a type of translator that takes the source code of a program written in a programming language as its input and produces an equivalent source code in the same or a different programming language.
LuaJIT, a just-in-time implementation of Lua, has an FFI that allows "calling external C functions and using C data structures from pure Lua code". [ 4 ] [ 5 ] : 35 Nim has an FFI which enables it to use source from C , C++ , and Objective-C .
This program creates a Lua state, passes the Lua state to IUPLua for initialization, and then opens and executes a Lua script against the Lua state. Or, the entire IUP state can be dynamically loaded via use of a Lua require or package.loadlib of IUPLua. The script(s) can later be compiled with the Lua compiler if needed.
The Lua API's design eliminates the need for manual reference counting (management) in C code, unlike Python's API. The API, like the language, is minimalist. Advanced functions are provided by the auxiliary library, which consists largely of preprocessor macros which assist with complex table operations. The Lua C API is stack based. Lua ...
DynASM replaces assembly code in C files with runtime writes to a 'code buffer', such that a developer may generate and then evoke code at runtime from a C program. It was created for LuaJIT 1.0.0 to make developing the just-in-time compiler easier.
Lua is dynamically typed. There's no static typing at all. From a syntactic point of view, think BASIC (or even COMAL) without line numbers and colons rather than C/C++/Java, Lisp/Scheme, or Forth. There's no begin, but most control structures have an end; for needs a do and if needs a then. {...} denote a table (expression), not a block of code.
c2nim is a source-to-source compiler (transcompiler or transpiler) meant to be used on C/C++ headers to help generate new Nim bindings. [41] The output is human-readable Nim code that is meant to be edited by hand after the translation process.
(NB. Uses the term Occam transpiler as a synonym for a source-to-source compiler working as a pre-processor that takes a normal occam program as input and derives a new occam source code as output with link-to-channel assignments etc. added to it thereby configuring it for parallel processing to run as efficient as possible on a network of ...
