Karaberus

A karaoke database.

Getting started

meson setup build -Dbuiltin_oidc_env=true -Dbuiltin_s3_env=true
meson compile -C build

On Windows this might not build out of the box, for now you can disable the native dependencies which should allow you to build:

meson setup build --reconfigure -Dno_native_deps=true

To run the app you need an oidc server and a s3, for development you can run meson compile -C build oidc to have a simple oidc server (-Dbuiltin_oidc_env=true has to be set during setup for this to work) and meson compile -C build s3 to have a S3 server (-Dbuiltin_s3_env=true has to be set during setup for this to work).

Then you can start the server with:

meson compile -C build run

This server also serves the web frontend so it should be useable.

To ease development on the web frontend it might be more convenient to run the dev server:

# from the root of the repo
cd ui
npm run dev

Custom S3 server

If you want to upload files (or run the S3 tests) to your own S3 server you have to set the following environment variables appropriately:

export KARABERUS_S3_ENDPOINT=localhost:9000
export KARABERUS_S3_KEYID=your_keyid
export KARABERUS_S3_SECRET=your_secret

Custom OIDC server

export KARABERUS_OIDC_ISSUER=http://localhost:9998/
export KARABERUS_OIDC_KEY_ID=karaberus
export KARABERUS_OIDC_CLIENT_ID=your_client_id
export KARABERUS_OIDC_CLIENT_SECRET=your_client_secret
export KARABERUS_OIDC_GROUPS_CLAIM=groups
export KARABERUS_OIDC_ADMIN_GROUP=admin
export KARABERUS_OIDC_SCOPES="openid profile email groups"
export KARABERUS_OIDC_JWT_SIGN_KEY="" # openssl rand -hex 32

Dakara

You can start a Dakara server and feed it from your instance:

export KARABERUS_DAKARA_BASE_URL="http://127.0.0.1:8000"
export KARABERUS_DAKARA_TOKEN="YOUR_DAKARA_TOKEN"

Tests

Tests can easily be run with:

meson test -C build

You can disable the S3 tests with the s3_tests configuration option of meson if you have not set up a S3 server:

meson setup build --reconfigure -Ds3_tests=disabled

If you run the tests in a git hook or similar, some tests can be slow to run and can be disabled if needed:

meson setup build --reconfigure -Dstaticcheck=false -Derrcheck=false

(These tests do run in the Github Actions so you should notice it at some point after pushing)

Development setup

Due to the current Meson setup, this project might not work well out of the box with regular go dev tools.

For the most part gopls should work without issues in the server module, if you need to work in the karaberus_tools (which interfaces with C libraries) you can set PKG_CONFIG_PATH to point to build/meson-uninstalled in the settings of gopls.

NOTE: You should not set PKG_CONFIG_PATH in your general environment (or at least in the environment in which you run Meson) as it might break meson when it needs to reconfigure itself (when meson.build files are modified most likely), because then it can find its own dependencies with pkg-config and get really confused when it won't find the libraries later in the build.

Dev Container / Codespaces

Once attached to the container, create and edit .vscode/settings.json as follows:

1. Copy .vscode/settings.example.json to .vscode/settings.json.

2. For KARABERUS_LISTEN_BASE_URL, keep it to http://localhost:5173 if you are running a Dev Container or a Codespace remotely attached to your local VS Code.
   For Codespaces in browser, set it to your editor URL, without trailing slash, and ending with -5173.app.github.dev instead of .github.dev.

3. If you want to use https://auth.japan7.bde.enseeiht.fr as KARABERUS_OIDC_ISSUER, ask for the required KARABERUS_OIDC_CLIENT_ID and KARABERUS_OIDC_CLIENT_SECRET on Discord. Otherwise, bring your own secrets.

Then use the provided launch tasks to compile and start both the server and the frontend.
