Fr

Simple bytecode compiled C-style compiled language.

Installation

pip install frscript

Command line launcher (fr)
Compiled language - Fast by design
File and Socket I/O - Low-level file operations and sockets.
HTTP library - A working HTTP/1.1 server/client library in examples/http/http_lib.fr, running on all three backends.
Fr OS target - fr native ... --target fr-os emits a static Fr OS userspace ELF using the Fr OS syscall ABI and user ISA profile.
Multiprocessing. - Easy threading with fork() and wait().
Python integration - You can use any Python libraries with Frscript.
Aggressive optimization - Purity call-graph analysis, interprocedural ranges, call-site specialization, pure constant-call folding, LICM, SROA/escape analysis, pure-function lookup tables, inline list fast paths and assembly peepholes.
Deterministic memory - Reference-counted native structs/lists/sets with function-scope cleanup, plus SROA and stack allocation for non-escaping values.
Modern memory model - Reference-semantics structs/lists/sets, scope-based reference counting, automatic stack allocation for non-escaping values, and a free-list native allocator.
Opt-in pointers - int*, &value, *p, pointer fields and pointer parameters, lowered directly to addresses in native code.
Stack-based VM - Fast and memory efficient.
Readable bytecode - Optimize hot code manually
WASM Backend - Run sandboxed code in web browsers.
