Running into an error when using Method Type Syntax for functions in favour of Function Type syntax

[FM35]

Bug description

export interface HelloWorld {
  sendMsg: (msg: string) => number
}

export interface HelloWorld {
  sendMsg(msg: string): number
}

When I run the yarn ts-to-zod command the first code block suceeds, but the second code block throws the following error:

However when I run the ts-to-zod command with the skipValidation flag, the process suceeds.

Input

Specified above

Specified above

Expected output

Should suceed

Not expected any schema for the function. But I believe the method type syntax shoouldn't break the process.

Actual output

Fails to run

// Actual Zod schemas

No output
Versions

• Typescript: v5.2.3
• Zod: v3.22.4

Hello @FM35,

Indeed, the generation process works with the --skipValidation flag set but it seems that the generated output does not correspond to the expected one, does it?

In the first case, I get

export const helloWorldSchema = z.object({
  sendMsg: z.function().args(z.string()).returns(z.number()),
});

while in the second case I see

export const helloWorldSchema = z.object({});

I don't see any tests covering the second case, so it seems to me that this syntax is not supported by ts-to-zod for now.

Hey @tvillaren , you're right. The output does not correspong to the expected one.

Will that format be supported anytime soon?

It's probably not too hard to add if you want to give it a try 😉

I'm curious, how do you use this in your code?
