obelisk-ios-libfrontend

Builds an obelisk frontend as a static library for use in an iOS project. Check out the companion project obelisk-ios-xcode, for an example of how to integrate this into an XCode project.

Adding the dependency

Add this package to the overrides in your obelisk project's default.nix:

obelisk-ios-libfrontend = haskellLib.dontStrip (self.callCabal2nix "obelisk-ios-libfrontend" (hackGet ./dep/obelisk-ios-libfrontend + "/exe") {});
obelisk-ios-libfrontendconfig = self.callCabal2nix "obelisk-ios-libfrontendconfig" (hackGet ./dep/obelisk-ios-libfrontend + "/lib") {};

Make sure to include dontStrip.

Adding iOS config to your frontend code

In your frontend/Frontend.hs, you'll need to add something like this:

...
import Obelisk.Frontend.iOS

...

iosConfig :: IO (IosConfig (R FrontendRoute))
iosConfig = do
  html <- fmap snd $ renderStatic $ myHtmlHead
  pure $ IosConfig (\_ -> frontend) $ mconcat
    [ "<!DOCTYPE html><html><head>"
    , html
    , "</head><body></body></html>"
    ]

Your Frontend.hs must export iosConfig.

Building

To build the static lib, run:

nix-build . -A ghcIosAarch64.obelisk-ios-libfrontend --argstr system "x86_64-darwin"
