I'm glad to hear that.
Hmm, this functionality is not defined in Lua5.1, so I'll see if there is a neat way around the issue.

I've added a Cause
attribute to the ApiError
. Now you can get the detailed error information in response to Type
value:
ApiErrorSyntax
,ApiErrorFile
:Cause
attribute- The others: The errfunc and the debug interface
You will want to write utilities like the following:
package main
import (
"github.com/yuin/gopher-lua"
"github.com/yuin/gopher-lua/parse"
)
func myDoString(L *lua.LState, source string) error {
fn, err := L.LoadString(source)
if err != nil {
if lerr := err.(*lua.ApiError); lerr != nil {
switch cause := lerr.Cause.(type) {
case *parse.Error:
println("Syntax error:", cause.Error())
println("Line: ", cause.Pos.Line)
println("Column: ", cause.Pos.Column)
case *lua.CompileError:
println("Compile error:", cause.Error())
println("Line: ", cause.Line)
default:
println(lerr.Error())
}
}
return err
}
L.Push(fn)
return L.PCall(0, lua.MultRet, L.NewFunction(func(L *lua.LState) int {
obj := L.Get(1)
dbg, _ := L.GetStack(1)
L.GetInfo("Slunf", dbg, lua.LNil)
println("Runtime error:", obj.String())
println("Line:", dbg.CurrentLine)
return 1 // retuens the original object
}))
}
func main() {
L := lua.NewState()
myDoString(L, `
print(1)
print(2)
pint(3)
print(4)
print(5)
`)
}

This is great! Thank you!
