console.trace definition is invalid in /lib/lib.dom.d.ts

[wallride]

console.trace(a,b,c,1,2,3) emits compilation error:

error TS2346: Supplied parameters do not match any signature of call target.

So, let's open the declaraion in /lib/lib.dom.d.ts:

interface Console {
    log(message?: any, ...optionalParams: any[]): void;
//  ......................
    trace(): void;
}

arguments should be the same as in log(message?: any, ...optionalParams: any[])

@wallride for now you can reopen the interface locally and define the missing signature as such:

interface Console {
    trace(...args: any[]): void;
}

@mhegazy, thanks for your reply! It was the first thing i've done. :) But transpiling via gulp-typescript still throws warnings. Though i've fixed every interface i could find.
Anyway, i supposed this issue would be useful for the typescript project.

[mhegazy]

just out of curiosity, what are the errors you were getting from gulp?

[wallride]

@mhegazy , oh just the same as i've written above.
Although i've optioned gulp-typescript to use TS from require('typescript'). And i've searched-and-replaced every d.ts file around typescript modules. Have no idea why it's still not satisfied. but errors don't block building process. so i move on.

but you do not need to replace the definition in lib.d.ts, you can just augment it. so in one of your files, just add the new definition.. here is what i mean in the playground: http://www.typescriptlang.org/Playground#src=interface%20Console%20%7B%0D%0A%20%20%20%20trace(...args%3A%20any%5B%5D)%3A%20void%3B%0D%0A%7D%0D%0A%0D%0Aconsole.trace(%22message%22)%3B%20%2F%2F%20OK%0D%0A

[wallride]

@mhegazy Yes, that is a some kind of solution. Thanks!
And declaration in lib.d.ts should be fixed anyway, i suppose :)

[mhegazy]

yup. the bug is open, should be fixed in TS1.8, but until then, no need to keep getting errors in your compilation.

PRs are welcomed. here is some documentation for adding new types to lib.d.ts: https://github.com/Microsoft/TypeScript/blob/master/CONTRIBUTING.md#contributing-libdts-fixes
