# Veilid Development
|
||
|
||
[](code_of_conduct.md)
|
||
|
||
## Introduction
|
||
|
||
This guide covers setting up environments for core, Flutter/Dart, and Python development. See the relevent sections.
|
||
|
||
## Obtaining the source code
|
||
|
||
```shell
|
||
git clone https://gitlab.com/veilid/veilid.git
|
||
```
|
||
|
||
## Dependencies
|
||
|
||
### GNU/Linux
|
||
|
||
Development of Veilid on GNU/Linux requires a Debian variant such as Debian
|
||
itself, Ubuntu or Mint. Pull requests to support other distributions would be
|
||
welcome!
|
||
|
||
Running the setup script requires:
|
||
|
||
- Rust
|
||
|
||
#### Optionally, to build for Android:
|
||
|
||
- Android SDK and NDK
|
||
|
||
You may decide to use Android Studio [here](https://developer.android.com/studio)
|
||
to maintain your Android dependencies. If so, use the dependency manager
|
||
within your IDE. If you plan on using Flutter for Veilid development, the Android Studio
|
||
method is highly recommended as you may run into path problems with the 'flutter'
|
||
command line without it. If you do so, you may skip to
|
||
[Run Veilid setup script](#Run Veilid setup script).
|
||
|
||
- build-tools;34.0.0
|
||
- ndk;26.3.11579264
|
||
- cmake;3.22.1
|
||
- platform-tools
|
||
- platforms;android-34
|
||
|
||
#### Setup Dependencies using the CLI
|
||
|
||
You can automatically install the prerequisites using this script:
|
||
|
||
```shell
|
||
./dev-setup/install_linux_prerequisites.sh
|
||
```
|
||
|
||
Otherwise, you may choose to use Android `sdkmanager`. Follow the installation
|
||
instructions for `sdkmanager`
|
||
[here](https://developer.android.com/studio/command-line/sdkmanager), then use
|
||
the command line to install the requisite package versions:
|
||
|
||
```shell
|
||
sdkmanager --install "platform-tools"
|
||
sdkmanager --install "platforms;android-34"
|
||
sdkmanager --install "build-tools;34.0.0"
|
||
sdkmanager --install "ndk;26.3.11579264"
|
||
sdkmanager --install "cmake;3.22.1"
|
||
```
|
||
|
||
Export environment variables and add the Android SDK platform-tools directory to
|
||
your path. See [instructions here](https://developer.android.com/tools/variables).
|
||
|
||
```shell
|
||
cat << EOF >> ~/.profile
|
||
export ANDROID_HOME=<path to sdk>
|
||
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/tools/bin:$ANDROID_HOME/platform-tools
|
||
EOF
|
||
```
|
||
|
||
#### Run Veilid setup script
|
||
|
||
Now you may run the Linux setup script to check your development environment and
|
||
pull the remaining Rust dependencies:
|
||
|
||
```shell
|
||
./dev-setup/setup_linux.sh
|
||
```
|
||
|
||
#### Run the veilid-flutter setup script (optional)
|
||
|
||
If you are developing Flutter applications or the flutter-veilid portion, you should
|
||
install Android Studio, and run the flutter setup script:
|
||
|
||
```shell
|
||
cd veilid-flutter
|
||
./setup_flutter.sh
|
||
```
|
||
|
||
### macOS
|
||
|
||
Development of Veilid on MacOS is possible on both Intel and ARM hardware.
|
||
|
||
Development requires:
|
||
|
||
- Xcode, preferably latest version
|
||
- Homebrew [here](https://brew.sh)
|
||
- Rust
|
||
|
||
#### Optionally, to build for Android:
|
||
|
||
- Android Studio
|
||
- Android SDK and NDK
|
||
|
||
You will need to use Android Studio [here](https://developer.android.com/studio)
|
||
to maintain your Android dependencies. Use the SDK Manager in the IDE to install the following packages (use package details view to select version):
|
||
|
||
- Android SDK Build Tools (34.0.0)
|
||
- NDK (Side-by-side) (26.3.11579264)
|
||
- Cmake (3.22.1)
|
||
- Android SDK 34
|
||
- Android SDK Command Line Tools (latest) (7.0/latest)
|
||
|
||
#### Setup command line environment
|
||
|
||
Export environment variables and add the Android SDK platform-tools directory to
|
||
your path. See [instructions here](https://developer.android.com/tools/variables).
|
||
|
||
```shell
|
||
cat << EOF >> ~/.zshenv
|
||
export ANDROID_HOME=$HOME/Library/Android/sdk
|
||
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/tools/bin:$ANDROID_HOME/platform-tools
|
||
EOF
|
||
```
|
||
|
||
#### Run Veilid setup script (macOS)
|
||
|
||
Now you may run the MacOS setup script to check your development environment and
|
||
pull the remaining Rust dependencies:
|
||
|
||
```shell
|
||
./dev-setup/setup_macos.sh
|
||
```
|
||
|
||
#### Run the veilid-flutter setup script (optional) (macOS)
|
||
|
||
If you are developing Flutter applications or the flutter-veilid portion, you should
|
||
install Android Studio, and run the flutter setup script:
|
||
|
||
```shell
|
||
cd veilid-flutter
|
||
./setup_flutter.sh
|
||
```
|
||
|
||
### Windows
|
||
|
||
For a simple installation allowing Rust development, follow these steps:
|
||
|
||
Install Git from <https://git-scm.com/download/win>
|
||
|
||
Install Rust from <https://static.rust-lang.org/rustup/dist/x86_64-pc-windows-msvc/rustup-init.exe> (this may prompt you to run the Visual Studio Installer, and reboot, before proceeding).
|
||
|
||
Optional (only if modifying capnp schema): Ensure that capnp.exe (for Cap’n Proto 1.0.1) is in a directory in your path. For example, it can be obtained from the <https://capnproto.org/capnproto-c++-win32-1.0.1.zip> distribution. Please note that the Windows Package Manager Community Repository (i.e., winget) as of 2023-09-15 has version 0.10.4, which is not sufficient.
|
||
|
||
Start a Command Prompt window.
|
||
|
||
```shell
|
||
git clone https://gitlab.com/veilid/veilid.git
|
||
cd veilid
|
||
cargo build
|
||
cd target
|
||
cd debug
|
||
veilid-server.exe
|
||
```
|
||
|
||
This may result in a popup window from local security software, asking whether you wish to allow network access by veilid-server.exe.
|
||
|
||
To use the CLI, navigate to the above `debug` directory in another Command Prompt window (while veilid-server.exe is still running), and type:
|
||
|
||
```shell
|
||
veilid-cli.exe
|
||
```
|
||
|
||
## Running the Application(s)
|
||
|
||
### Veilid Server
|
||
|
||
In order to run the `veilid-server` locally:
|
||
|
||
```shell
|
||
cd ./veilid-server
|
||
cargo run
|
||
```
|
||
|
||
In order to see what options are available:
|
||
|
||
```shell
|
||
cargo run -- --help
|
||
```
|
||
|
||
#### Configuration
|
||
|
||
`veilid-server` has a wealth of configuration options. Further documentation on
|
||
the format of the `veilid-server.conf` file may be found [in the project /doc
|
||
directory](./doc/config/veilid-server-config.md).
|
||
|
||
When running `veilid-server` in a Unix-like environment, the application will
|
||
look for its config file under `/etc/veilid-server/`. If the config file is not
|
||
found in this location, `veilid-server` will follow the XDG user directory spec
|
||
and look in `~/.config/veilid-server`.
|
||
|
||
When running under Windows, the `veilid-server.conf` file may be created at
|
||
`C:\Users\<user>\AppData\Roaming\Veilid\Veilid\`, and when running under macOS,
|
||
at `/Users/<user>/Library/Application Support/org.Veilid.Veilid`.
|
||
|
||
### Veilid CLI
|
||
|
||
In order to connect to your local `veilid-server`:
|
||
|
||
```shell
|
||
cd ./veilid-cli
|
||
cargo run
|
||
```
|
||
|
||
Similar to `veilid-server`, you may see CLI options by typing:
|
||
|
||
```shell
|
||
cargo run -- --help
|
||
```
|
||
|
||
## Building the Application
|
||
|
||
### Linux Packages
|
||
|
||
Veilid server and cli can be built locally using the
|
||
[Earthly](https://earthly.dev/) framework. After [installing earthly on your
|
||
local machine](https://earthly.dev/get-earthly), you may use the `earthly` cli
|
||
to initiate a build:
|
||
|
||
```shell
|
||
earthly +package-linux
|
||
```
|
||
|
||
This will assemble all dependencies and build `.deb` packages for both amd64 and
|
||
arm64 platforms. Earthly, built on Docker, caches build layers, so after a
|
||
longer first build, subsequent builds should be much quicker.
|
||
|
||
During development, you may want to kick off specific build steps. To see a list
|
||
of the build steps configured, consult the `Earthfile`, or you may use the
|
||
`earthly` cli:
|
||
|
||
```shell
|
||
earthly ls
|
||
```
|
||
|
||
## Updating bindings
|
||
|
||
When changing Veilid API, bindings must be updated to reflect the changes.
|
||
For each language, perform the listed steps and commit changed files.
|
||
|
||
### Dart
|
||
|
||
1. Update sources in `veilid-flutter/lib`, ignoring `*.freezed.*` and `*.g.*`
|
||
2. Run `dart run build_runner build` inside `veilid-flutter`, allow to delete existing files if asked
|
||
|
||
### Python
|
||
|
||
1. Run `cargo build --bin=veilid-server`
|
||
2. Run `./veilid-python/update_schema.sh`
|
||
3. Update sources in `veilid-python/veilid`
|
||
|
||
### WASM
|
||
|
||
1. Update sources in `veilid-wasm/src`
|
