Readme for quickjs-hs-0.1.2.1
[back to package description]quickjs-hs
This package provides a Haskell wrapper for the QuickJS Javascript Engine.
Features
The functionality is quite basic and is currently limited to:
- evaluating JS code
- calling a JS function in the global scope
- marshalling Aeson Values to and from JSValues.
Examples
Evaluate an expression:
import Quickjs
one_plus_two = quickjs $ do
res <- eval "1+2"
liftIO $ print res
Declare a function and call it on an argument:
call_f = quickjs $ do
_ <- eval_ "f = (x) => x+1"
res <- eval "f(2)"
liftIO $ print res
Pass a Haskell value (which has a ToJSON instance) to the JS runtime:
aeson_marshall = quickjs $ do
_ <- eval_ "f = (x) => x+1"
res <- withJSValue (3::Int) $ \x -> call "f" [x]
liftIO $ print res
