Windows 10: Announcing TypeScript 2.5 RC

Notice that unusedError is never referenced in the above example. TypeScript 2.5 introduces a late-stage ECMAScript feature to make the catch binding optional in try/catch statements. That means we can just omit unusedError altogether:

Code: let contents; try { contents = fs.readFileSync('.config_file').toString('utf8'); } catch { // File might not exist, just fall back to some defaults. contents = createDefaultContents(); }[/quote]
Thanks to Tingan Ho for his contribution on this feature!

Deduplicated and redirected packages

When importing using the Node module resolution strategy in TypeScript 2.5, the compiler will now check whether files originate from “identical” packages. If a file originates from a package with a package.json containing the same name and version fields as a previously encountered package, then TypeScript will redirect itself to the top-most package. This helps resolve problems where two packages might contain identical declarations of classes, but which contain private members that cause them to be structurally incompatible. It also reduces the memory and runtime footprint of the compiler and language service.

The --preserveSymlinks compiler flag

TypeScript 2.5 brings the preserveSymlinks flag, which parallels the behavior of the --preserve-symlinks flag in Node.js. This flag also exhibits the opposite behavior to Webpack’s resolve.symlinks option (i.e. setting TypeScript’s preserveSymlinks to true parallels setting Webpack’s resolve.symlinks to false, and vice-versa).

In this mode, references to modules and packages (e.g. imports and /// <reference type="..." /> directives) are all resolved relative to the location of the symbolic link file, rather than relative to the path that the symbolic link resolves to. For a more concrete example, we’ll defer to the documentation on the Node.js website.

What next?

While we’ll continue to improve TypeScript before the full 2.5 release, we also have a few other ideas for TypeScript 2.6 that are under way. Some things we’ll be working on in the meantime are improvements to TypeScript’s --watch mode, and integration with other tools that have file-watching functionality. Our aim is to ensure that as codebases grow larger, TypeScript can give lightning-fast turnaround between the time that you save a file, and the time that you can reload your project. You can keep an eye on our pull request for changes to --watch for the work we’ve done so far.

Thanks for reading, and we hope you give our release candidate a try!

Windows Explorer crashing

I tried removing the Windows Security Update and after a reboot, problem still occurs when file explorer sees a typescript file. File explorer crashes.

 

Features in Firmware Update PR 1.2 and its Expected Release date ?

im guessing you dl'd a rc. some people have reported issues with the rc going around, such as problems with the conversations app, etc.



official release will be as soon as theyve verified the stability of the OS.



next upgrade will be either a maemo pr1.3 or meego. nokia have already announced that meego may be available as a standalone flash image or as a dual boot image, both of which require flashing through your pc. it will most likely not be available as a standalone
update.



nokia have also mentioned that they will try to implement all existing features of maemo5 into meego, but they have mentioned that there may be some minor functionality lost.



personally i would just wait for someone to release a review about meego before id touch it.
