haxala1r	df1fad751f	compiler: constants are now put directly inside the program's global table where possible (i.e. whenever the global value would be constant-ish anyway).	2026-05-17 20:05:47 +03:00

haxala1r	68b8916d63	repl: added a repl. currently compiles every program as a new one however. this needs to be fixed with incremental compilation	2026-05-17 20:03:38 +03:00

haxala1r	c9694af826	vm and compiler: removed automatic currying, and several other modifications to the language	2026-05-10 17:23:42 +03:00
haxala1r	947d2274bb	vm: modified StoreLocal and StoreGlobal logic to be more consistent with the rest of the VM, ... and modified the emit module to emit a Pop instruction after every top-level expression. This change was required because the semantics of the language are pretty clear. Every expression evaluates to something - meaning that, in the corresponding bytecode, every expression must have exactly a +1 effect on the data stack. I.e. every expression, when its corresponding bytecode is evaluated, has the effect of pushing something to the stack. For values that are not used by another expression, this value must be immediately popped. Some optimizations could target this area. For example, for top-level expressions, it is obvious to the compiler that their values will not be used - hence the compiler can use optimized versions of some instructions (like StoreLocal and StoreGlobal) to simply never leave the value on the stack, thus saving an extra Pop instruction (good for performance and code size). Same thing applies in function bodies, letrec/let/begin bodies, where expressions whose values are never used may appear. It may also make sense to introduce registers to the VM, for the purposes of parameter passing (such that up to a predetermined number of parameters are progressively passed through registers instead of pushed to the stack). This would pair well with eliminating unnecessary currying in the byte code.	2026-04-26 01:20:05 +03:00
haxala1r	d846046c4a	Big changes: ... Compiler and VM are now working well enough to support larger programs. A test program is included and executed immediately upon running the executable. A more feature complete read-eval-print loop is planned.	2026-04-26 00:55:43 +03:00
