picol.go

Original http://oldblog.antirez.com/post/picol.html

Sample use:

funcCommandPuts(i*picol.Interp, argv []string, pdinterface{}) (string, error) {
iflen(argv) !=2 {
return"", fmt.Errorf("Wrong number of args for %s %s", argv[0], argv)
}
fmt.Println(argv[1])
return"", nil
}
...interp:=picol.InitInterp()
// add core functionsinterp.RegisterCoreCommands()
// add user functioninterp.RegisterCommand("puts", CommandPuts, nil)
// evalresult, err:=interp.Eval(string(buf))
iferr!=nil {
fmt.Println("ERROR", err, result)
} else {
fmt.Println(result)
}

UPDATE

I forked this forked this project because there was a bug in the parser.go file that prevented it from compiling. Also, the project name also janked the golang tools.

In the sample code above CommandPuts has a final param pd interface{}. The value of this param is whatever value the user passed in when registering. I do not particularly see what the benefit is unless there is some sort of fork.

PrivData

In the callframe there is privData that is set when calling a proc()
