This is the repository for Makepad, a new way to build UIs in Rust for both native and the web.

Makepad consists of Makepad Framework and Makepad Studio.

Makepad Framework is our UI framework. It consists of multiple crates, but the top level crate is makepad-widgets. For a further explanation of Makepad Framework, please see the README for that crate.

Makepad Studio is a prototype of an IDE that we've built using Makepad Framework. It's still under heavy development, but our eventual goal with Makepad Studio is to create an IDE that enables the design of an application to be changed at runtime. The main crate for Makepad Studio is makepad-studio. Please see the README for that crate for more.

makepad-example-ironfish

makepad-example-simple

To build the Makepad crates you first need to install Rust. https://www.rust-lang.org/tools/install

Our native builds work on the stable Rust toolchain. However, some of the errors generated by Makepad at runtime (particulary those originating in our DSL) do not contain line information unless you use the nightly Rust toolchain. Moreover, our web builds only work on nightly for now. For this reason, we recommend that you build Makepad using the nightly Rust toolchain.

For the non standard build targets (apple ios, apple tvos, android, wasm) we have a buildtool called 'cargo-makepad' that you need to install.

Install it from a local clone of the repo:

cargo install --path=./tools/cargo_makepad

Or install it from crates.io (the last published version, it may be older than the repo):

cargo install cargo-makepad

The way how you've installed cargo-makepad will affect how you will install Makepad studio, if you choose to use it (more later).

Now this tool can be used to install toolchains per platform needed

cargo makepad wasm install-toolchain

cargo makepad apple ios install-toolchain

cargo makepad apple tvos install-toolchain

cargo makepad android --abi=all install-toolchain

Makepad studio allows you to easily build and view the examples, and it uses cargo-makepad internally so be sure to install cargo-makepad as shown above.

If you've installed cargo-makepad from a local clone of the repo, then either

• build & run Makepad studio from the local clone:

  cargo run -p makepad-studio --release

• or install makepad-studio from the local clone:

  cargo install --path=./studio

Or install it from crates.io (the last published version, it may be older than the repo)::

cargo install makepad-studio

If you build the wasm applications, you can open it on:

Makepad is a cross-platform UI framework written in Rust. It is in active development, but is already usable to build quick prototypes and simple (or even complicated UI) applications.

One of the key features of the Makepad is its ability to simply, and quickly, build and run applications on multiple platforms, including MacOS, Windows, Linux, Android, iOS, and WebAssembly.

Here are the current/latest instructions on how to build and run Makepad applications on the different platforms.

We will assume the following: Name of application: makepad-example-simple

It can be changed to any one of the existing example apps in the Makepad examples folder.

Follow step 1 commands below for initial setup of the Makepad build and run environment. After step 2, you may choose any one or more of the platforms you're interested in building for.

Replace projects with your own directory name.

cd ~/projects

git clone https://github.com/makepad/makepad.git

or

git clone git@github.com:makepad/makepad.git

cd ~/projects/makepad
git branch rik

cd ~/projects/makepad
cargo install --path ./tools/cargo_makepad

rustup toolchain install nightly

cd ~/projects/makepad/examples
ls -l

All examples in this directory have the application name of makepad-example- prefix plus the name of directory.

Running on Desktop is the quickest way to try out an example app.

cd ~/projects/makepad/examples/simple
cargo run

or

cd ~/projects/makepad
cargo run -p makepad-example-simple

And there should be a desktop application window now running (may need to click on the icon on MacOS's Dock to show it)

cargo makepad android install-toolchain

Open either the Android emulator or connect to a real Android device use adb command to make sure there's a single device connected properly, then install and run as below:

cd ~/projects/makepad
cargo makepad android run -p makepad-example-simple --release

The application will be installed and launch on either the emulator or device.

xcode-select --install
cargo makepad apple ios install-toolchain

For iOS, the process is slightly more complicated. The steps involved are:

1. Enable your iPhone's Developer Mode, please see instructions here: Enable Developer Mode
2. Setup an Apple Developer account
3. Setup an empty skeleton project in XCode
   1. File -> New -> Project to create a new "App"
   2. Set the Product Name as makepad-example-simple (used in --app later)
   3. Set the Organization Identifier to a value of your choice, for this example we will use my.test (used in --org later)
   4. Setup the Project Signing & Capabilities to select the proper team account
4. In XCode, Build/Run this project to install and run the app on the simulator and device
5. Once the simulator and device has the "skeleton" app installed and running properly, then it is ready for Makepad to install its application.

We will run the cargo makepad apple ios command, similar to Android build above, but there are some 2 to 6 additional parameters that need to be filled in:

--org

First few parts of the organization identifier. Usually in the form of com.somecompany or org.orgname, etc. This is the same value used to setup the initial skeleton app above. For this example:

my.test

--app

The name of the application or the project. This is the same as the Product Name used to setup the initial skeleton app above. In this case:

makepad-example-simple

cd ~/projects/makepad
cargo makepad apple ios \
  --org=my.test \
  --app=makepad-example-simple \
  run-sim -p makepad-example-simple --release

For installing on real device, the process is more involved due to possibility of multiple profiles and signing identities and target devices. For this reason, Makepad provides a list command to show all the local provisioning profiles, signing identities and connected devices, which can be used as the value for the subsequent command arguments.

For example, first run the following command:

cd ~/projects/makepad
cargo makepad apple list

This command will print out the list of all provisioning profiles, signing identities, and device identifiers on the current system. The user has to decide and choose the ones that he/she needs to use for each type.

Once decided, run the folloiwng command and fill in the unique starting characters chosen from the output.

cargo makepad apple ios \
 --profile=unique-starting-hex-string-of-provisioning-profiles \
 --cert=UNIQUE_STARTING_HEX_STRING-of-signing-certificates \
 --device-identifier=UNIQUE-STARTING-HEX-STRING-of-devices \
 --org=my.test \
 --app=makepad-example-simple \
 run-device -p makepad-example-simple –release
 

The application will be installed and launched on either the emulator or real device. (Make sure the device is connected and unlocked)

Running the Makepad application as a WASM build is as simple as a single command. The sript will automatically generate the necessary index.html and other files and also start a local webserver at port 8010. After running the command below, just open your browser to http://127.0.0.1:8010/ in order for the app to load and run.

cargo makepad wasm install-toolchain

cargo makepad wasm run -p makepad-example-simple --release

For WASM to work in browsers, your web server must

• serve the MIME types correctly (as is common), and

• set the following two headers.

  Cross-Origin-Embedder-Policy: require-corp
  Cross-Origin-Opener-Policy: same-origin
  

  This is NOT common on public web servers like GitHub Pages. And it can't be set with <meta http-equiv="..." content="..."></meta> in index.html.

  A workaround - but possibly for non-private browser mode only: use gzuidhof/coi-serviceworker:

  1. Let's say that you use Makepad's experiments/html_experiment. Build it with cargo makepad wasm build -p makepad-experiment-html.
  2. Copy coi-serviceworker.min.js (or coi-serviceworker.js) to target/makepad-wasm-app/debug/makepad-experiment-html.
  3. Edit target/makepad-wasm-app/debug/makepad-experiment-html/index.html and under <head> add: <script src="coi-serviceworker.min.js"></script> (or <script src="coi-serviceworker.js"></script>).
  4. If use build a release with cargo makepad wasm build -p makepad-experiment-html --release, then the build directory is makepad/target/makepad-wasm-app/release/makepad-experiment-html instead.
  5. If there is any initiation, it will be run twice. To control that, follow gzuidhof/coi-serviceworker#14.
  6. If this works well, incorporate it to Makepad's tools/cargo_makepad/src/wasm/compile.rs and platform/src/os/web/ and create a pull request.

These are commands that need to be run at least once initially to setup Makepad development environments. They should also be run once in a while or when there are updates to the cargo_makepad script.
