### Submitting translations:
Thank you so much for your interest in translating BetterYTM!
Before submitting a translation, please check on [this document](./assets/translations/README.md) if the language you want to translate to has already been translated and how many strings are still missing.
#### Adding translations for a new language:
To submit a translation, please follow these steps:
1. Copy the contents of the default translation file [`assets/translations/en_US.json`](./assets/translations/en_US.json)
2. Replace the `en_US` part of the file name with the language code and locale code of the language you want to translate to
3. Translate the strings inside the file, while making sure not to change the keys on the left side of the colon and to preserve the placeholders with the format %n (where n is any number starting at 1).
4. If you like, you may also create a translation for the [`README-summary.md`](./README-summary.md) file for display on the userscript distribution sites
Please duplicate the file `README-summary.md` and call it `README-summary-languageCode_localeCode.md` and place it in the [`assets/translations/`](./assets/translations/) folder.
5. If you want to submit a pull request with the translated file:
1. Duplicate the `en_US.json` file in the folder [`assets/translations/`](./assets/translations/) by keeping the format `languageCode_localeCode.json`
2. Edit it to your translated version and keep the left side of the colon unchanged
3. Create the mapping in `assets/locales.json` by copying the English one and editing it (please make sure it's alphabetically ordered)
4. Add your name to the respective `authors` property in [`assets/locales.json`](./assets/locales.json)
5. Test your changes by following [this section](#setting-up-the-project-for-local-development), then submit your pull request
6. Alternatively send it to me directly, [see my homepage](https://sv443.net/) for contact info
Make sure you also add your language to the contents of [`assets/locales.json`](./assets/locales.json)
#### Editing an existing translation:
To edit an existing translation, please follow these steps:
1. Set up the project for local development by following [this section](#setting-up-the-project-for-local-development)
Make sure you have forked the repository and cloned your fork instead of cloning the original repository.
2. Find the file for the language you want to edit in the folder [`assets/translations/`](./assets/translations/)
3. Run the command `npm run tr-format -- -p -o=language_LOCALE`, where `language_LOCALE` is the part of the file name before the `.json` extension
This will prepare the file for translation by providing the missing keys once in English and once without any value and also formatting the file to have the same structure as the base file `en_US.json`
4. Edit the strings inside the file, while making sure not to change the keys on the left side of the colon and to preserve the placeholders with the format %n (where n is any number starting at 1).
5. Make sure there are no duplicate keys in the file
6. Run the command `npm run tr-format -- -o=language_LOCALE` to make sure the file is formatted correctly
7. Test for syntax errors and update translation progress with the command `npm run tr-progress`
8. Open the file [`assets/translations/README.md`](./assets/translations/README.md) to see if you're still missing any untranslated keys (you don't have to translate them all, but it would of course be nice)
9. I highly encourage you to test your changes to see if the wording fits into the respective context by following [this section](#setting-up-the-project-for-local-development)
10. Submit your pull request by [clicking here](https://github.com/Sv443/BetterYTM/compare/) and setting the `compare:` dropdown to your fork
11. Check that the CI checks just above the comment box pass and then wait for the pull request to be reviewed and merged
### Setting up the project for local development:
#### Requirements:
1. Have Node.js, npm and Git installed
2. Clone this repository (if you plan on contributing to the project, please [click here to fork it](https://github.com/Sv443/BetterYTM/fork) and clone your fork instead)
3. Switch to the `develop` branch by running `git checkout develop` in the project root.
Skip this step if you are using your own forked repository.
4. Open a terminal in the project root and run `npm i`
5. Copy the file `.env.template` to `.env` and modify the variables inside to your needs.
6. Now you can run `npm run dev` to build the userscript and host it on a development server or check out the other commands below
#### These are the CLI commands available after setting up the project:
- **`npm i`**
Run once to install dependencies
- **`npm run dev`**
This is the command you want to use to locally develop and test BetterYTM.
It watches for any changes, then rebuilds and serves the userscript on port 8710, so it can be updated live if set up correctly in the userscript manager (see [extras](#extras)).
Once it has finished building, a link will be printed to the console. Open it to install the userscript.
You can also configure request logging and more in `.env` and `src/tools/serve.ts`, just make sure to restart the dev server after changing anything.
- **`npm run build-prod`**
Builds the userscript for production for all hosts with their respective options already set.
Outputs the files using a suffix predefined in the `package.json` file.
Use this to build the userscript for distribution on all host/CDN platforms.
- **`npm run build -- `**
Builds the userscript with custom options
Arguments:
- `--config-mode=` - The mode to build in. Can be either `production` or `development` (default)
- `--config-branch=` - The GitHub branch to target. Can be any branch name, but should be `main` for production and `develop` for development (default)
- `--config-host=` - The host to build for. Can be either `github` (default), `greasyfork` or `openuserjs`
- `--config-assetSource=` - Where to get the resource files from. Can be either `local` or `github` (default)
- `--config-suffix=` - Suffix to add just before the `.user.js` extension. Defaults to an empty string
Shorthand commands:
- `npm run build-prod-base` - Sets `--config-mode=production` and `--config-branch=main`
Used for building for production, targeting the main branch
- `npm run build-develop` - Sets `--config-mode=development`, `--config-branch=develop` and `--config-assetSource=github`
Used for building for experimental versions, targeting the develop branch
- **`npm run lint`**
Builds the userscript with the TypeScript compiler and lints it with ESLint. Doesn't verify *all* of the functionality of the script, only syntax and TypeScript errors!
- **`npm run gen-readme`**
Updates the README files by inserting different parts of generated sections into them.
- **`npm run tr-progress`**
Checks all translation files for missing strings and updates the progress table in `assets/translations/README.md`
- **`npm run tr-format -- `**
Reformats all translation files so they match that of the base file `en_US.json`
This includes sorting keys and adding the same empty lines and indentation.
Arguments:
- `--prep` or `-p` - Prepares the files for translation via GitHub Copilot by providing the missing key once in English and once without any value
- `--only=""` or `-o=""` - Only applies formatting to the files of the specified locales. Has to be a comma separated list (e.g. `-o="fr_FR,de_DE"`)
- `--include-based` or `-b` - Also includes files which have a base locale specified
- **`npm run tr-prep`**
Shorthand for `npm run tr-format -- -p` (see above)
- **`npm run --silent invisible -- ""`**
Runs the passed command as a detached child process without giving any console output.
Remove `--silent` to see npm's info and error messages.
- **`npm run node-ts -- `**
Runs the TypeScript file at the given path using the regular node binary and the node-ts loader.
Also enables source map support and disables experimental warnings.
#### Extras:
When using ViolentMonkey, after letting the command `npm run dev` run in the background, open [`http://localhost:8710/BetterYTM.user.js`](http://localhost:8710/BetterYTM.user.js) and select the `Track local file` option.
This makes it so the userscript automatically updates when the code changes.
Note: the tab needs to stay open on Firefox or the script will not update itself.
### Developing a plugin that interfaces with BetterYTM:
BetterYTM has a built-in interface based on events and exposed global constants and functions that allows other userscripts to benefit from its features.
If you want your plugin to be displayed in the readme and possibly inside the userscript itself, please [submit an issue using the plugin submission template](https://github.com/Sv443/BetterYTM/issues/new/choose)
These are the ways to interact with BetterYTM; constants, events and global functions:
- Static interaction is done through constants that are exposed through the global `BYTM` object, which is available on the `window` object.
These read-only properties tell you more about how BetterYTM is currently being run.
You can find all properties that are available and their types in the `declare global` block of [`src/types.ts`](src/types.ts)
- Dynamic interaction is done through events that are dispatched on the `window` object.
They all have the prefix `bytm:eventName` and are all dispatched with the `CustomEvent` interface, meaning their data can be read using the `detail` property.
You can find all events that are available and their types in [`src/interface.ts`](src/interface.ts)
Additionally BetterYTM has an internal system called SiteEvents. They are dispatched using the format `bytm:siteEvent:eventName`
You may find all SiteEvents that are available and their types in [`src/siteEvents.ts`](src/siteEvents.ts)
Note that the `detail` property will be an array of the arguments that can be found in the event handler at the top of [`src/siteEvents.ts`](src/siteEvents.ts)
- Another way of dynamically interacting is through global functions, which are also exposed by BetterYTM through the global `BYTM` object.
You can find all functions that are available in the `InterfaceFunctions` type in [`src/types.ts`](src/types.ts)
There is also a summary with examples [below.](#global-functions)
Additionally to those functions, the namespace `BYTM.UserUtils` is also exposed, which contains all exported members from the [UserUtils library.](https://github.com/Sv443-Network/UserUtils)
All of these interactions require the use of `unsafeWindow`, as the regular window object is pretty sandboxed in userscript managers.
If you need specific events to be added or modified, please [submit an issue.](https://github.com/Sv443/BetterYTM/issues/new/choose)
Static interaction Example (click to expand)
#### Example:
```ts
const BYTM = unsafeWindow.BYTM;
console.log(`BetterYTM was built in '${BYTM.mode}' mode`);
console.log(`BetterYTM's locale is set to '${BYTM.locale}'`);
console.log(`BetterYTM's version is '${BYTM.version} #${BYTM.buildNumber}'`);
```
Dynamic interaction examples (click to expand)
#### Basic format:
```ts
window.addEventListener("bytm:eventName", (event) => {
// can have any type, but usually it's an object or undefined
const { detail } = event as CustomEvent<{ foo: string }>;
console.log(detail.foo);
});
// for listening to SiteEvents:
window.addEventListener("bytm:siteEvent:eventName", (event) => {
// always typed as array / tuple
const { detail } = event as CustomEvent<[ foo: HTMLElement ]>;
console.log(detail[0]);
});
```
#### Practical Example:
```ts
// listening to generic events:
window.addEventListener("bytm:ready", () => {
console.log("The DOM is loaded and all BetterYTM features have been initialized");
});
window.addEventListener("bytm:lyricsLoaded", (event) => {
const { detail } = event as CustomEvent<{ type: "current" | "queue", artists: string, title: string, url: string }>;
console.log(`Lyrics URL for "${detail.artists} - ${detail.title}" has been loaded: ${detail.url}`);
if(detail.type === "current")
console.log("This is from the currently playing song");
else
console.log("This is from a song in the queue");
});
// listening to a SiteEvent:
window.addEventListener("bytm:siteEvent:queueChanged", (event) => {
const { detail } = event as CustomEvent<[ queueItem: HTMLElement ]>;
console.log(`The queue has been changed. It now contains ${detail[0].childNodes.length} items`);
});
```
**For global function examples [see below.](#global-functions)**
### Shimming for TypeScript without errors & with autocomplete:
In order for TypeScript to not throw errors while creating a plugin, you need to shim the types for BYTM.
To do this, create a .d.ts file (for example `bytm.d.ts`) and add the following code:
```ts
declare global {
interface Window {
BYTM: {
// add types here
};
}
}
```
You may specify all types that you need in this file.
To find which types BetterYTM exposes, check out the `declare global` block in [`src/types.ts`](src/types.ts)
You may also just copy it entirely, as long as all the imports also exist in your project.
An easy way to do this might be to include BetterYTM as a Git submodule, as long as you ***stick to only using type imports***
### Global functions and classes:
These are the global functions and classes that are exposed by BetterYTM through the `unsafeWindow.BYTM` object.
The usage and example blocks on each are written in TypeScript but can be used in JavaScript as well, after removing all type annotations.

> ```
>
> Description:
> Adds a listener to the specified SelectorObserver instance that gets called when the element(s) behind the passed selector change.
> These instances are created by BetterYTM to observe the DOM for changes.
> See the [UserUtils SelectorObserver documentation](https://github.com/Sv443-Network/UserUtils#selectorobserver) for more info.
>
> Arguments:
> - `observerName` - The name of the SelectorObserver instance to add the listener to. You can find all available instances and which parent element they observe in the file [`src/observers.ts`](src/observers.ts).
> - `selector` - The CSS selector to observe for changes.
> - `options` - The options for the listener. See the [UserUtils SelectorObserver documentation](https://github.com/Sv443-Network/UserUtils#selectorobserver)

> Usage:
> ```ts
> unsafeWindow.BYTM.onInteraction(
> element: HTMLElement,
> callback: (event: MouseEvent | KeyboardEvent) => void,
> listenerOptions?: AddEventListenerOptions
> ): void
> ```
>
> Description:
> Adds accessible event listeners to the specified element for button or link-like keyboard and mouse interactions.
> All events passed to the callback function automatically have the default behavior prevented and stop immediate propagation, meaning no other listener of the same type will be called.
> For keyboard events this only happens as long as the captured key is a valid interaction key (Space, Enter).
>
> Arguments:
> - `element` - The element to add the listeners to
> - `callback` - The function to call when the element is interacted with
> - `listenerOptions` - Optional event listener options (same as the third argument of `addEventListener`, shared between the keyboard and mouse event listeners)
>
> Example (click to expand)
>
> ```ts
> const myButton = document.querySelector("button#myButton");
>
> unsafeWindow.BYTM.onInteraction(myButton, (event) => {
> if(event instanceof MouseEvent)
> console.log("The button was clicked");
> else if(event instanceof KeyboardEvent)
> console.log("The button was activated with the keyboard (Space / Enter)");
> }, {
> // if `once` is set, when either the mouse or keyboard event are triggered once,
> // the other listener is automatically removed as well to prevent double triggering
> once: true,
> // you can pass `capture` to listen in the capture phase (helpful for triggering before other listeners),
> // or an AbortController's `signal` to be able to abort the listener
> });
> ```
>
> #### getVideoTime()
> Usage:
> ```ts
> unsafeWindow.BYTM.getVideoTime(precision?: number): Promise
> ```
>
> Description:
> Returns the current video time in seconds, with the given `precision` (2 decimal digits by default).
> Rounds down if the precision is set to 0. The maximum average available precision on YTM is 6.
>
> In case the time can't be determined on YT, mouse movement is simulated to bring up the video time element and read it.
> In order for that edge case not to throw an error, the function would need to be called in response to a user interaction event (e.g. click) due to the strict automated interaction policy in browsers, otherwise an error can be thrown.
> Resolves with a number of seconds or `null` if the time couldn't be determined.
>
> Example (click to expand)
>
> ```ts
> try {
> // get the video time with 3 decimal digits
> const videoTime = await unsafeWindow.BYTM.getVideoTime(3);
> console.log(`The video time is ${videoTime}s`);
> }
> catch(err) {
> console.error("Couldn't get the video time, probably due to automated interaction restrictions");
> }
> ```
>
> #### getThumbnailUrl()
> Usage:
> ```ts
> unsafeWindow.BYTM.getThumbnailUrl(
> watchID: string,
> qualityOrIndex: "maxresdefault" | "sddefault" | "hqdefault" | "mqdefault" | "default" | 0 | 1 | 2 | 3
> ): string
> ```
>
> Description:
> Returns the URL to the thumbnail of the video with the specified watch/video ID and quality.
> If a number is passed, 0 will return a low quality thumbnail and 1-3 will return a low quality frame from the video.
>
> Arguments:
> - `watchID` - The watch/video ID of the video to get the thumbnail for
> - `qualityOrIndex` - The quality or index of the thumbnail to get. Quality strings sorted highest resolution first: `maxresdefault` > `sddefault` > `hqdefault` > `mqdefault` > `default`. If no quality is specified, `maxresdefault` (highest resolution) is used.
>
> Example (click to expand)
>
> ```ts
> const thumbnailUrl = unsafeWindow.BYTM.getThumbnailUrl("dQw4w9WgXcQ", "maxresdefault");
> console.log(thumbnailUrl); // "https://i.ytimg.com/vi/dQw4w9WgXcQ/maxresdefault.jpg"
> ```
>
> #### getBestThumbnailUrl()

> - Can be opened, closed, mounted, unmounted and destroyed at any time for full control.
> - The dialog is fully responsive and can be used on any screen size, but will not exceed the provided maximum width and height.
> - Scrollability of the body is automatically removed and the body is set to be inert (ignore keyboard input) automatically. Also works with multiple dialogs open at the same time!
> - The dialog can be closed by clicking the background, pressing the escape key or clicking the close button (freely configurable).
> - Features many helper methods and events to make it more flexible and easier to work with.
> - Has an optional small mode for a more compact appearance.
> - If needed, the relatively uniform CSS naming conventions make it easy for the appearance to be overridden by a BetterYTM plugin or userstyle.
>
> Options properties:
> | Property | Description |
> | :-- | :-- |
> | `id: string` | ID that gets added to child element IDs - has to be unique and conform to HTML ID naming rules! |

> These are the additional methods that are exclusive to the `BytmDialog` class:
> - `open(e?: MouseEvent | KeyboardEvent): Promise`
> Opens the dialog - also mounts it if it hasn't been mounted yet.
> Prevents default action and immediate propagation if an event is passed.
> Resolves once the dialog is fully mounted and opened.
> - `close(e?: MouseEvent | KeyboardEvent): void`
> Closes the dialog - also unmounts and destroys it if the `destroyOnClose` option is set to true.
> Prevents default action and immediate propagation if an event is passed.
> - `isOpen(): boolean`
> Returns true if the dialog is currently open, false if not.
> - `isMounted(): boolean`
> Returns true if the dialog is currently mounted, false if not.
> - `mount(): Promise`
> Mounts the dialog to the DOM without making it visible - can be called before opening the dialog for the first time to pre-load all elements.
> Resolves once the dialog is fully mounted in the DOM.
> - `unmount(): void`
> Removes the dialog from the DOM.
> - `remount(): Promise`
> Unmounts and mounts the dialog again.
> This can be used to re-render the dialog's contents with new information.
> Resolves once the dialog is fully mounted in the DOM.
> - `destroy(): void`
> Unmounts and removes the dialog from the DOM and removes all event listeners.
> Should be called when the dialog is no longer needed.
> - `static getLastDialogId(): string`
> Returns the ID of the last dialog that was opened.
> This can be used to check if a dialog is currently open and to get its ID for further use.
> Static method usage: `unsafeWindow.BytmDialog.getLastDialogId()` (doesn't need a `new` instance)
> - `static getOpenDialogs(): string[]`
> Returns the IDs of all open dialogs, topmost (last opened) first.
> Static method usage: `unsafeWindow.BytmDialog.getOpenDialogs()` (doesn't need a `new` instance)
>
>
