Report errors (and quickfixes) for incorrect JSDoc

[ghost]

TypeScript Version: nightly (2.4.0-dev.20170515)

Code

/**
 * @param abcdeg A parameter
 */
function f(abcdefg: number) {
    abcdeg;
}

Expected behavior:

Can fix spelling for either abcdeg.

Actual behavior:

Does not work in jsdoc.

[mhegazy]

well.. that means it is an error to have this JSDoc.

if we report this, why not report other things in jsdoc as well.. like invalid tags @params instead of @param...

[mhegazy]

I think this is subsumed by #13371

[mhegazy]

closing in favor of #13371

Let's use this issue to track semantic errors for jsdoc. #13371 tracks syntactic errors.

There is still the open question of whether these errors (and associated quick fixes) should only be availble in js files with // @ts-check or in TS files as well.

Might there be optional report of missing JSDoc @param and @return?

And how about detection of a mismatch between actual return and @return/@returns?

@brettz9 Enable "checkJs": true inside compilerOptions in your tsconfig.json and you should get an error if a @return tag is incorrect.

/** @return {number} */
function g() { return ""; } // Error

Enable "noImplicitAny": true (or better, "strict": true) and you will get an error if a @param tag is missing.

function f(x) {} // Error, 'x' is implicitly 'any'
