Myst::VM

Inherits Reference / Object

Constructors

new(source : IO = IO::Memory.new, *, source_name : String = "eval_input", with_stdlib? : Bool = true, use_stdios? : Bool = false, product? : Bool = true)

This constructor is not really meant to be called unless you're initializing an "empty" vm Instead for_file and for_content should be used Many of these parameters would be rarely used All having default values, i don't really think the amount of parameters is a problem

Class methods

eval(string_source : String, *, with_stdlib? : Bool = true, use_stdios? : Bool = false, product? : Bool = true)

for_content(string_source : String, *, with_stdlib? : Bool = true, use_stdios? : Bool = false, product? : Bool = true)

for_file(source_file : String, *, with_stdlib? : Bool = true, use_stdios? : Bool = false, product? : Bool = true)

run(source_file : String, *, with_stdlib? : Bool = true, use_stdios? : Bool = false, product? : Bool = true)

Instance methods

errput

errput=(io : IO)

eval(program : String)

Tries to run the provided string as a myst program

input

input=(io : IO)

interpreter

output

output=(io : IO)

print_ast(io : IO = STDOUT)

program=(program)

require(*programs)

reset!(with_stdlib? : Bool = @with_stdlib)

run(program : Node)

Standard interface for running a parsed program. Using this interface ensures that every program goes through the proper phases of interpretation (semantic analysis, interpretation, etc.).

run

Runs the @program property

run(*programs)

Runs file(s) and IO(s)

semantic_visitor

use_stdios!

use_stdios=(use_stdios : Bool)

Helper method to quickly set all io to std or new

use_stdios?
