# mobiletest
An example of building a clojure library for iOS with graalvm native-image.
## Game of Life Example
See `examples/gol`
## Public Beta
Try the public beta iOS app through test flight https://testflight.apple.com/join/GLOKMgFX
## Prerequisites
1. Download java's arm64 static libraries built for ios. They can be downloaded using `download-deps`
```sh
$ scripts/download-deps
```
2. Setup graalvm and make sure your clojure project is graalvm compatible. https://github.com/BrunoBonacci/graalvm-clojure
Make sure `GRAALVM_HOME` is set and is on your path before starting.
```
export GRAALVM_HOME=/Library/Java/JavaVirtualMachines/graalvm-ce-java11-VERSION/Contents/Home
export PATH=$GRAALVM_HOME/bin:$PATH
```
3. Install [Graalvm LLVM Backend](https://www.graalvm.org/reference-manual/native-image/LLVMBackend/)
```sh
$ gu install llvm-toolchain
```
## Usage
1. Compile your clojure project
```sh
$ ./scripts/compile-shared
```
This can take a while.
2. Open the xcode project in xcode/MobileTest/MobileTest.xcodeproj
3. Select "Any iOS Device(arm64)" or your connected device as the build target. (iOS Simulator not supported yet)
4. Build and run
## Membrane Example
An example project that uses [membrane](https://github.com/phronmophobic/membrane) for UI can be found under xcode/TestSkia/TestSkia.xcodeproj. It also starts a sci repl that can be used for interactive development. Simply connect to the repl and start hacking! To update the UI, just `reset!` the main view atom. Example scripts below.
### Usage
1. Compile `./scripts/compile-membrane`
2. Open xcode/TestSkia/TestSkia.xcodeproj
3. Build and run
4. The console will print the IP addresses available. Connect to repl on your device using the IP address and port 23456.
5. Hack away!
### Example scripts
Hello World!
```clojure
(require '[membrane.ui :as ui])
(require '[com.phronemophobic.mobiletest.membrane :refer
[main-view]])
(def red [1 0 0])
(reset! main-view
(ui/translate 50 100
(ui/with-color red
(ui/label "Hello World!"
(ui/font nil 42)))))
```
Simple Counter
```clojure
(require '[membrane.ui :as ui])
(require '[com.phronemophobic.mobiletest.membrane :refer
[main-view]])
(def my-count (atom 0))
(defn counter-view []
(ui/translate 50 100
(ui/on
:mouse-down
(fn [pos]
(swap! my-count inc)
nil)
(ui/label (str "the count "
@my-count)
(ui/font nil 42)))))
(add-watch my-count ::update-view (fn [k ref old updated]
(reset! main-view (counter-view))))
(reset! my-count 0)
```
Basic Drawing
```clojure
(require '[membrane.ui :as ui])
(require '[com.phronemophobic.mobiletest.membrane :refer
[main-view]])
(def pixels (atom []))
(defn view []
(ui/on
:mouse-down
(fn [pos]
(swap! pixels conj pos))
[(ui/rectangle 600 800)
(into []
(map (fn [[x y]]
(ui/translate x y
(ui/with-color [0 0 1 1]
(ui/rectangle 10 10)))))
@pixels
)])
)
(add-watch pixels ::update-view (fn [k ref old updated]
(reset! main-view (view))))
(reset! pixels [])
```
