Add stack traceback to Lua error message. #140

actboy168 · 2020-10-29T07:27:59Z

This change adds a stack traceback to Lua error messages to make it easier to find the error. At the same time, the call to setter and getter is changed from lua_pcall to lua_call, because now it is possible to know exactly where the error occurred in the setter and getter through the error message.

e.g.

<rml>
    <head>
        <script>
            function ButtonClick(document)
                document.title = {}
            end
        </script>
    </head>>
    <body>
        <button onclick="ButtonClick(document)">Click</button>
    </body>
</rml>

Before:

Document.__newindex for title: bad argument #2 to '?' (string expected, got table)

After:

bad argument #2 to '?' (string expected, got table)
stack traceback:
        [C]: in ?
        [C]: in metamethod 'newindex'
        [string "--test.rml..."]:4: in function 'ButtonClick'
        [string "ButtonClick(document)"]:1: in function <[string "ButtonClick(document)"]:1>
