# fx_cast
No full public release yet! Pre-release beta version is incomplete and likely buggy.
## Supported platforms
* Linux
* macOS
* Windows
## Installing
Install the Firefox extension and companion bridge application. Downloads can be found on the website or in the [GitHub releases](https://github.com/hensm/fx_cast/releases) section.
macOS/Windows versions have installers, Linux packages can be installed via the command line:
````sh
# Debian/Ubuntu
sudo dpkg -i fx_cast_bridge.deb
# Fedora
sudo dnf install fx_cast_bridge-<version>.<arch>.rpm
````
### Package managers
* #### Arch Linux (AUR) - https://aur.archlinux.org/packages/fx_cast/
````sh
yay -S fx_cast
````
## Building
### Requirements
* NodeJS
* dpkg (for building deb packages)
* rpm (for building rpm packages)
* macOS (for building macOS installer packages)
#### Installing dependencies
macOS:
````sh
brew install dpkg rpm
````
Debian/Ubuntu:
````sh
sudo apt install dpkg rpm
````
Fedora:
````sh
sudo dnf install dpkg rpm-build
````
Archlinux:
At the moment, `pkg` has a [bug](https://github.com/zeit/pkg/issues/584), until fixed nodejs has to be downgraded to `10.12.0`:
```sh
sudo pacman -S nvm dpkg
yay -S rpm-org
echo 'source /usr/share/nvm/init-nvm.sh' >> ~/.bashrc
nvm install 10.12.0
```
### Instructions
````sh
git clone https://github.com/hensm/fx_cast.git
cd fx_cast
npm install
npm run build
npm run install-manifest
````
This will build the ext and app, outputting to `dist/`:
* #### `dist/app/`
... contains the bridge binary and manifest with the path pointing that binary. `install-manifest` copies this manifest to the proper location (or adds its current location to the registry).
* #### `dist/ext/`
... contains the unpacked extension.
Watching ext changes:
````sh
npm run watch --prefix ./ext
````
Launch Firefox and auto-reload on rebuild (run in separate terminal):
````sh
npm run start --prefix ./ext
````
### Packaging
Packaging currently only possible for macOS/Linux. macOS packages can only be created on macOS, Linux .deb/.rpm packages can be built on any platform with `dpkg-deb` and `rpmbuild` binaries.
* #### `dist/app/`
... contains the installer package: `fx_cast_bridge.(pkg|deb|rpm|exe)`
* #### `dist/ext/`
... contains the built extension in the format `fx_cast-<version>.zip`.
Build and package app and extension for current platform:
````sh
npm run package
````
Build and package app for linux platforms:
````sh
npm run package --prefix ./app -- --platform=linux --packageType=deb
npm run package --prefix ./app -- --platform=linux --packageType=rpm
````
##### Package script arguments
* `--platform` `"win"`,`"mac"`,`"linux"`
Select the platform to build for.
* `--packageType` `"deb"`,`"rpm"`
Select the package type. Defaults to `deb`. Only relevant when building for Linux.
### Testing
Testing requires geckodriver (or chromedriver for Chrome parity testing). See [selenium-webdriver](https://www.npmjs.com/package/selenium-webdriver#installation) installation instructions (ignore `npm install`).
Test results will be displayed within the opened browser tab.
````sh
npm run build --prefix ./app
npm run install-manifest
npm run package --prefix ./ext
npm test
SELENIUM_BROWSER=chrome npm test
````
## Usage
Extension can be loaded from `about:debugging` as a temporary extension.
Most sites won't load the cast API unless the browser presents itself as Chrome. The extension includes a method of spoofing the user agent string, sites can be whitelisted via the options page. Whitelist entries are specified as [match patterns](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Match_patterns). To whitelist all sites, add `<all_urls>` to the whitelist, though this could cause breakage on random sites.
HTML5 media elements have a "Cast..." context menu item that triggers a sender application. Only works on remote (non-local) media that isn't DRM-encumbered.
Cast-enabled websites will load the sender API shim and display a cast button as in Chrome, provided there are no bugs/incompatibilities with the shim.

Note: Since it seems to be causing confusion, this project does not use electron. The electron-chromecast library was only used as a reference for the intitial implementation of the API shim.
