Wiish (Why Is It So Hard) GUI framework might one day make it easy to develop, package and deploy auto-updating, cross-platform applications for desktop and mobile. If it succeeds, maybe the name will have to change :)

Wiish is currently ALPHA quality software. Don't make anything with it unless you're willing to rewrite it when this package changes.

1. Install Nim and nimble

2. Install Wiish:

   nimble install https://github.com/iffy/wiish.git

3. Find out what other dependencies you need:

   wiish doctor

4. Create a project and run it:

   wiish init somedir
   cd somedir
   wiish run

See wiish --help for more, but here are other examples. Some only work within a Wiish project:

wiish run --os ios-simulator
wiish run --os android
wiish build

Wiish provides:

1. A wiish command line tool for running, building and packaging apps.
2. A wiish Nim library (i.e. import wiish/...) for app-specific helpers (e.g. auto-updating, asset-access, etc...)
3. Plugins for different GUI frameworks: import wiish/plugins/...

Wiish uses a plugin system to support various GUI frameworks:

• wiish/plugins/webview - For webview apps based on oskca/webview.

The GUI component is designed to work separately from other features (e.g. auto-updating, packaging, etc...) so that different GUI libraries can be swapped in/out.

It is hoped that more plugins will be introduced for other GUI frameworks.

The following shows the support matrix of automated tests. Actual support may be better or worse than described here.

• Yes - For wiish run, this means that the application starts and continues running for a few seconds. For wiish build it means the build succeeded.
• No - Means it failed
• - - Means it's not supported (and isn't planned to be supported)
• Planned - Means it doesn't currently work, but we're planning on getting it to work.
• Untested - Means that it might work when run on a real computer, but our automated tests aren't yet capable of testing it. For instance, we haven't yet figured out how to run GUI applications on Windows so those are mostly marked Untested.

See the examples directory for more examples of how to use this library. You can also initialize a project using these examples with wiish init. See wiish init --help for information.

When using the wiish/plugins/webview plugin, you send/receive strings between JavaScript and your Nim like this:

In JavaScript do this:

window.wiish = window.wiish || {};
wiish.onReady = () => {
    wiish.onMessage(message => {
        // Handle message from Nim
    })
    wiish.sendMessage("Hello Nim! -Sincerely JavaScript");
}

In Nim do this:

import wiish/plugins/webview/desktop
var app = newWebviewDesktopApp()
app.life.addListener proc(ev: DesktopEvent) =
  case ev.kind
  of desktopAppStarted:
    var win = app.newWindow(
      url = some_html_url,
    )
    win.onReady.handle:
      win.sendMessage("Hello JavaScript! -Sincerely Nim")
    win.onMessage.handle(msg):
      discard "Handle message from JavaScript"
app.start()

This library works as advertised, but it is a huge mess. I'm learning as I'm going, and trying to wrangle all these platforms is ridiculous. I happily welcome suggestions (and pull requests).
