validate

Validator

Basic example

Given a file type_error.wat with the following content:

(module $quickstart
  (func $f
    i32.const 20
    i32.const 22
    i32.add
    i32.add
    drop
  )
  (start $f)
)

Running the validator is as simple as:

$ owi validate ./type_error.wat
type mismatch (pop)
[35]

You can also print a more detailed trace with the --debug option:

$ owi validate ./type_error.wat --debug
parsing      ...
checking     ...
grouping     ...
assigning    ...
rewriting    ...

type mismatch (pop)
