Nice!

eslint is not happy though:

/home/travis/build/apache/cordova-plugin-file/www/resolveLocalFileSystemURI.js
  58:18  error  Expected exception block, space or tab after '/*' in comment  spaced-comment
  58:18  error  Expected space or tab before '*/' in comment                  spaced-comment

Ouch, doesn't like your editor settings:

By the way: There is no real testing going on for Windows itself, we are currently working on fixing that.

PS: You can probably use eslint --fix (or a similar command) to fix that automatically.

I can fix this irrelevant formalia you criticize. But beside that, it'll be more important to be concerned of real functionality and usefulness of the module. There is stil a problem, that working on known folders / file libraries like this will only work on Windows 10, not on 8.x I don't need to mention the mess with Android and memory cards :/ It might be a much better approach to use a syntax for symbolic path placeholders. At least Documents, Pictures, Music and Videos. And at least for current-user, user: and maybe public/default for systems without multi-user management. Eventual use of memory card should be transparent to the caller. The pseudo-path will always access the root folder of the file library, sub-folders maybe added with path delimiter /

I can fix this irrelevant formalia you criticize.

It is not me criticizing, but the eslint tool that we use on all/most Apache Cordova software. I just copied its output from CI over. As this enables us to keep a common code standard in Apache Cordova projects, it is very much relevant though.

It might be a much better approach to use a syntax ...

That sounds pretty sensible. Best open an issue in this repo and describe the changes you propose and the reasoning behind them. Sounds like a bigger change though, and would most probably require a new major release.

@janpio: I've now installed VisualLinter and will try to check for the tab/space inconsistencies again. I've seen a typo, too: Property videoDirectory should be called videosDirectory. I'll change that, too. I can work on the concept for virtual known folders maybe later. For the moment the extension enables at least on current Windows 10 devices automatic inter-store app and desktop app <--> store app file exchange. I'll be back at this plugin after other more urgent work on cordova-plugin-clippingcamera, cordova-plugin-media-capture and creating a new plugin for useful interaction with usb/virtual-com-port devices on pc devices first, sorry… ;)

No worry, as long as you don't forget to fix this up we will be happy ;)

Hello,

I've been testing this pull request on the following device: Windows 10 pro 1511 build 10586.1176

It seems like Windows.Storage.UserDataPaths is always undefined. I did some research and it looks like you need the Windows 10 Fall Creators Update (introduced v10.0.16299.0) to use the UserDataPaths.

Only specific Windows 10 devices can download this update which means that not all Windows 10 devices support this extension(like mine).

Is there any other way to get access to the known folders ?

I'm not a pro in native Windows development so any tips are welcome.

[janpio]

Restart tests.

CI: Once more please.
