Using enums under tstype

[jonamsalem]

Hey! Is there any way to use my enum under the tstype label in a struct. For example:

say i have an enum :

type Status string
const (
    Pending  Status = "Pending"
    Active   Status = "Active"
    Inactive Status = "Inactive"
    Unknown  Status = "Unknown"
)

and under my struct i wanna use
Status Status(or String) json:"status,omitempty" tstype:"Status"

rather than having to generate the status label as tstype:" 'Pending' | 'Active' | 'Inactive' | 'Unknown' ";

Hi @jonamsalem

I don't think this is possible directly, it is hard/impossible to know for the current parser to know all the possible values, at least in its current state (it would have to be a more full compiler).

Here is a posisble workaround, you put

type Status string

in a separate file that you ignore in the Tygo config.

Then in the frontmatter, you manually write out the type:

frontmatter: |
      type Status = "'Pending' | 'Active' | 'Inactive' | 'Unknown'";

Or if you want to be even more strict about it:

  type Status = "typeof Pending | typeof Active | typeof Inactive | typeof Unknown";

Then you would be able to use tstype:"Status".
Of course it's not perfect - but this may just get the job done :).

If your union consists of 1000 items, this is of course not really workable - but maybe it's doable to type it manually.

I see. Thank you so much!
