@ -77,16 +77,9 @@ VM, waiting to run some code!
You can tell the VM to execute a string of Wren source code like so:
:::c
WrenInterpretResult result = wrenInterpret(vm,
"<where>",
"System.print(\"Hi!\")");
WrenInterpretResult result = wrenInterpret(vm, "System.print(\"Hi!\")");
The first string parameter is a "source path". It's just an arbitrary string
that describes where the source code is from. It's what shows up in stack traces
if a runtime error occurs in the code. It can be whatever you want as long as
it's not `NULL`.
The other string is the chunk of code to execute&mdash;a series of one or more
The first string is the chunk of code to execute&mdash;a series of one or more
statements separated by newlines. Wren runs this code in a special "main"
module. Each time you call this, the code is run in the same module. This way,
top-level names defined in one call can be accessed in later ones.
