Capturing anything but : using @~ failed on (

[ethanyzhang]

Hello!

I have a ColumnHandle that I wanted to parse in this format:

<column name>:<data type>:<column index>

An example could be:

id:int:1
cohort:varchar(16):2

I defined my struct like:

type HiveColumnHandle struct {
	ColumnName  string          `parser:"@Ident ':'"`
	DataType    string          `parser:"@~':' ':'"`
	ColumnIndex int             `parser:"@Int"`
}

I was hoping by specifying @~':', I could parse varchar(16) into DataType but lexing stopped at ( and complained that it is an unexpected token.

Could you help shed some light what is going wrong here?

Thanks a lot!!

Almost there, you're just missing a repetition: parser:"@(~':')+ ':'"
