x/tools/cmd/stringer to accept string input

[suntong]

What version of Go are you using (go version)?

$ go version
go version go1.19.3 linux/amd64

What did you want?

Given the name of a (signed or unsigned) integer type T that has constants
defined, stringer will create a new self-contained Go source file implementing

func (t T) String() string

That method will translate the value of a Pill constant to the string representation
of the respective constant name, so that the call fmt.Print(painkiller.Aspirin) will
print the string "Aspirin".

I need to pass the string representation from command line and get the corresponding integer value of type T.
EG, giving an input string "Aspirin", I need a method to get the corresponding value of Aspirin (1).

It is not possible at the moment right? Hope it'll be some day.
And meanwhile, while waiting, what shall I do? Can I still make use of the automatic created methods / code, or I should be looking for something entirely different?

Thanks

The challenge is when using the -linecomment=true. IE the value are different from the name.

See https://go.dev/play/p/t8n91_GF0Od

Given a string "Or", I need to get its value of "|". thx.
