East end functions, by Phil Nash

1auto doesItBlend() -> bool;
2auto whatsYourFavouriteNumber() -> int;
3auto add(double a, double b) -> double;
4void setTheControls();

Why = means assignment?

integer algol_x; algol_x := 5;

cpl_by_value = 5;
cpl_by_reference ~= 5;
cpl_by_subst ≡ 5;

apl x ← 5

ALGOL -> CPL -> BCPL -> B -> C

    • “The parts that are hard but critical (window surface, choice of driver backend, input) are vastly underspecified.”

Live++ – C and C++ live coding

  • Product page
    • Windows only, programs must be built with MSVC, 32 or 64 bit
    • 30 day trial, then EUR 119 (ind.) or EUR 199 (business) per year

Live++ enables live coding (hot-reload) for C/C++ applications, combining the power of rapid iteration with the speed of a compiled language. Live++ compiles your changes in the background, directly patching the machine code of the running executable(s). It links against existing code and data symbols, automatically persisting the state of global symbols, function static variables, and the like. It works with any kind of C/C++ code and requires neither plug-ins nor a debugger or IDE.
