Electron API History Migration Guide

This document demonstrates how to add API History blocks to existing APIs.

API history information

Here are some resources you can use to find information on the history of an API:

Критические изменения

• breaking-changes.md

Additions

• git blame
• Release notes
• electron-api-historian

Пример

информация

The associated API is already removed, we will ignore that for the purpose of this example.

If we search through breaking-changes.md we can find a function that was deprecated in Electron 25.0.

<!-- docs/breaking-changes.md -->
### Deprecated: `BrowserWindow.getTrafficLightPosition()`

`BrowserWindow.getTrafficLightPosition()` has been deprecated, the
`BrowserWindow.getWindowButtonPosition()` API should be used instead
which returns `null` instead of `{ x: 0, y: 0 }` when there is no custom
position.

<!-- docs/api/browser-window.md  -->
#### `win.getTrafficLightPosition()` _macOS_ _Deprecated_

Returns `Point` - The custom position for the traffic light buttons in
frameless window, `{ x: 0, y: 0 }` will be returned when there is no custom
position.

We can then use git blame to find the Pull Request associated with that entry:

$ grep -n "BrowserWindow.getTrafficLightPosition" docs/breaking-changes.md 
523:### Deprecated: `BrowserWindow.getTrafficLightPosition()`
525:`BrowserWindow.getTrafficLightPosition()` has been deprecated, the

    docs: update E24/E25 breaking changes (#37878) <-- This is the associated Pull Request

Verify that the Pull Request is correct and make a corresponding entry in the API History:

информация

Refer to the API History section of styleguide.md for information on how to create API History blocks.

#### `win.getTrafficLightPosition()` _macOS_ _Deprecated_

<!--
```YAML history
deprecated:
  - pr-url: https://github.com/electron/electron/pull/37878
    breaking-changes-header: deprecated-browserwindowgettrafficlightposition
```
-->

Returns `Point` - The custom position for the traffic light buttons in
frameless window, `{ x: 0, y: 0 }` will be returned when there is no custom
position.

You can keep looking through breaking-changes.md to find other breaking changes and add those in.

You can also use git log -L :<funcname>:<file>:

$ git log --reverse -L :GetTrafficLightPosition:shell/browser/native_window_mac.mm

    feat: make trafficLightPosition work for customButtonOnHover (#26789)

Verify that the Pull Request is correct and make a corresponding entry in the API History:

#### `win.getTrafficLightPosition()` _macOS_ _Deprecated_

<!--
```YAML history
added:
  - pr-url: https://github.com/electron/electron/pull/22533

```
-->

Returns `Point` - The custom position for the traffic light buttons in
frameless window, `{ x: 0, y: 0 }` will be returned when there is no custom
position.

We will then look for when the API was originally added:

$ git log --reverse -L :GetTrafficLightPosition:shell/browser/native_window_mac.mm
