JS Closure Compiler, @param syntax for array destructuring?












3















I'm unable to find the correct syntax for @param annotations for array destructuring. E.g.:



let destructArray = ([one, two]) => one + two;


I tried imitating the object destructuring syntax:



// object destructuring works

/** @param {{one: number, two: number}} o */

let destructObject = ({one, two}) => one + two;



// array destructuring does not works

/** @param {[one: number, two: number]} a */

let destructArray = ([one, two]) => one + two;


But that's not valid syntax. I've also tried /** @param {Array<number>} a */, but then it expects a single parameter named a, not one and two.



Does anyone know the correct syntax to use for array destructuring?

    For others who, like me, hoped JSDoc's destructuring support would solve this, it appears not. I answered hoping it would (you can see the answer here: pastebin.com/dNgVLCMd), but the OP said it didn't work. (Thanks for letting me know, junvar, and good luck -- it may be that CC doesn't support this yet.)

Closure Compiler does not currently support different types at different array indexes. So in this case, all you do is:



/** @type {function(!Array<number>):number} */

let destructArray = ([one, two]) => one + two;

            A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

            Image
            0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
