Hi
I'm trying to define a structure within let block but it fails. Having the
structure outside works perfectly fine.
sample.ur
fun main()=
let
fun debugMe a =
alert a
structure AB = Mymaths.Make(struct
val callback = debugMe
end)
fun callMe () =
x <- AB.simple "test";
debug x
in
return <xml>
<body>
<h1> Sample </h1>
<button value="Click Me" onclick={fn _ => callMe()}></button>
</body>
</xml>
end
Above code throws compile error, where as the following code compiles &
runs fine :
fun debugMe a =
alert a
structure AB = Mymaths.Make(struct
val callback = debugMe
end)
fun main()=
let
fun callMe () =
x <- AB.simple "test";
debug x
in
return <xml>
<body>
<h1> Sample </h1>
<button value="Click Me" onclick={fn _ => callMe()}></button>
</body>
</xml>
end
Any idea what's going wrong ? Can't a structure be created within let ? If
no, then is there an alternative ?
