thorin::plug::refly

The refly plugin allows to reify and reflect Thorin's own representation.

Dependencies

.import compile;

Types

.ax %refly.Code: * -> *;

Reify/Reflect

%refly.reify

Yields the internal representation of a Thorin expression as %refly.Code.

.ax %refly.reify: Π.[T: *][T] -> [%refly.Code T], normalize_reify;

%refly.reflect

Converts a %refly.Code back to a Thorin expression.

.ax %refly.reflect: Π.[T: *][%refly.Code T] -> T, normalize_reflect;

Inspect

%refly.gid

Retuns the internal thorin::Def::gid of the argument.

.ax %refly.gid: Π.[T: *][T] -> .Nat, normalize_gid;

%refly.dbg

Debugs a given expression.

• tmp: Prints debug information of a given expression at construction time and vanishes afterwards.
• perm: Permanently debugs at every construction. Gets removed at codegen preparation in thorin::plug::refly::RemoveDbgPerm.

.let %refly.error   = 0;
.let %refly.warn    = 1;
.let %refly.info    = 2;
.let %refly.verbose = 3;
.let %refly.debug   = 4;
 
.ax %refly.dbg(tmp, perm): Π.[T: *][.Nat, T] -> T, normalize_dbg;

Manipulate

%refly.refine

Sets the ith operand of the reified Code e to x.

// TODO type infere - not working right now
.ax %refly.refine: Π [E: *, X: *][e: %refly.Code E, i: .Nat, x: %refly.Code X] -> %refly.Code E, normalize_refine;

Passes and Phases

Passes

.ax %refly.remove_dbg_perm_pass: %compile.Pass;
