# Electron Documentation Style Guide
|
|
|
|
These are the guidelines for writing Electron documentation.
|
|
|
|
## Headings
|
|
|
|
* Each page must have a single `#`-level title at the top.
|
|
* Chapters in the same page must have `##`-level headings.
|
|
* Sub-chapters need to increase the number of `#` in the heading according to
|
|
their nesting depth.
|
|
* The page's title must follow [APA title case][title-case].
|
|
* All chapters must follow [APA sentence case][sentence-case].
|
|
|
|
Using `Quick Start` as example:
|
|
|
|
```markdown
|
|
# Quick Start
|
|
|
|
...
|
|
|
|
## Main process
|
|
|
|
...
|
|
|
|
## Renderer process
|
|
|
|
...
|
|
|
|
## Run your app
|
|
|
|
...
|
|
|
|
### Run as a distribution
|
|
|
|
...
|
|
|
|
### Manually downloaded Electron binary
|
|
|
|
...
|
|
```
|
|
|
|
For API references, there are exceptions to this rule.
|
|
|
|
## Markdown rules
|
|
|
|
This repository uses the [`markdownlint`][markdownlint] package to enforce consistent
|
|
Markdown styling. For the exact rules, see the `.markdownlint.json` file in the root
|
|
folder.
|
|
|
|
There are a few style guidelines that aren't covered by the linter rules:
|
|
|
|
<!--TODO(erickzhao): make sure this matches with the lint:markdownlint task-->
|
|
* Use `sh` instead of `cmd` in code blocks (due to the syntax highlighter).
|
|
* Keep line lengths between 80 and 100 characters if possible for readability
|
|
purposes.
|
|
* No nesting lists more than 2 levels (due to the markdown renderer).
|
|
* All `js` and `javascript` code blocks are linted with
|
|
[standard-markdown](https://www.npmjs.com/package/standard-markdown).
|
|
* For unordered lists, use asterisks instead of dashes.
|
|
|
|
## Picking words
|
|
|
|
* Use "will" over "would" when describing outcomes.
|
|
* Prefer "in the ___ process" over "on".
|
|
|
|
## API references
|
|
|
|
The following rules only apply to the documentation of APIs.
|
|
|
|
### Title and description
|
|
|
|
Each module's API doc must use the actual object name returned by `require('electron')`
|
|
as its title (such as `BrowserWindow`, `autoUpdater`, and `session`).
|
|
|
|
Directly under the page title, add a one-line description of the module
|
|
as a markdown quote (beginning with `>`).
|
|
|
|
Using the `session` module as an example:
|
|
|
|
```markdown
|
|
# session
|
|
|
|
> Manage browser sessions, cookies, cache, proxy settings, etc.
|
|
```
|
|
|
|
### Module methods and events
|
|
|
|
For modules that are not classes, their methods and events must be listed under
|
|
the `## Methods` and `## Events` chapters.
|
|
|
|
Using `autoUpdater` as an example:
|
|
|
|
```markdown
|
|
# autoUpdater
|
|
|
|
## Events
|
|
|
|
### Event: 'error'
|
|
|
|
## Methods
|
|
|
|
### `autoUpdater.setFeedURL(url[, requestHeaders])`
|
|
```
|
|
|
|
### Classes
|
|
|
|
* API classes or classes that are part of modules must be listed under a
|
|
`## Class: TheClassName` chapter.
|
|
* One page can have multiple classes.
|
|
* Constructors must be listed with `###`-level headings.
|
|
* [Static Methods](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/static)
|
|
must be listed under a `### Static Methods` chapter.
|
|
* [Instance Methods](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes#Prototype_methods)
|
|
must be listed under an `### Instance Methods` chapter.
|
|
* All methods that have a return value must start their description with
|
|
"Returns `[TYPE]` - \[Return description]"
|
|
* If the method returns an `Object`, its structure can be specified using a colon
|
|
followed by a newline then an unordered list of properties in the same style as
|
|
function parameters.
|
|
* Instance Events must be listed under an `### Instance Events` chapter.
|
|
* Instance Properties must be listed under an `### Instance Properties` chapter.
|
|
* Instance Properties must start with "A \[Property Type] ..."
|
|
|
|
Using the `Session` and `Cookies` classes as an example:
|
|
|
|
```markdown
|
|
# session
|
|
|
|
## Methods
|
|
|
|
### session.fromPartition(partition)
|
|
|
|
## Static Properties
|
|
|
|
### session.defaultSession
|
|
|
|
## Class: Session
|
|
|
|
### Instance Events
|
|
|
|
#### Event: 'will-download'
|
|
|
|
### Instance Methods
|
|
|
|
#### `ses.getCacheSize()`
|
|
|
|
### Instance Properties
|
|
|
|
#### `ses.cookies`
|
|
|
|
## Class: Cookies
|
|
|
|
### Instance Methods
|
|
|
|
#### `cookies.get(filter, callback)`
|
|
```
|
|
|
|
### Methods and their arguments
|
|
|
|
The methods chapter must be in the following form:
|
|
|
|
```markdown
|
|
### `objectName.methodName(required[, optional]))`
|
|
|
|
* `required` string - A parameter description.
|
|
* `optional` Integer (optional) - Another parameter description.
|
|
|
|
...
|
|
```
|
|
|
|
#### Heading level
|
|
|
|
The heading can be `###` or `####`-levels depending on whether the method
|
|
belongs to a module or a class.
|
|
|
|
#### Function signature
|
|
|
|
For modules, the `objectName` is the module's name. For classes, it must be the
|
|
name of the instance of the class, and must not be the same as the module's
|
|
name.
|
|
|
|
For example, the methods of the `Session` class under the `session` module must
|
|
use `ses` as the `objectName`.
|
|
|
|
Optional arguments are notated by square brackets `[]` surrounding the optional
|
|
argument as well as the comma required if this optional argument follows another
|
|
argument:
|
|
|
|
```markdown
|
|
required[, optional]
|
|
```
|
|
|
|
#### Argument descriptions
|
|
|
|
More detailed information on each of the arguments is noted in an unordered list
|
|
below the method. The type of argument is notated by either JavaScript primitives
|
|
(e.g. `string`, `Promise`, or `Object`), a custom API structure like Electron's
|
|
[`Cookie`](api/structures/cookie.md), or the wildcard `any`.
|
|
|
|
If the argument is of type `Array`, use `[]` shorthand with the type of value
|
|
inside the array (for example,`any[]` or `string[]`).
|
|
|
|
If the argument is of type `Promise`, parametrize the type with what the promise
|
|
resolves to (for example, `Promise<void>` or `Promise<string>`).
|
|
|
|
If an argument can be of multiple types, separate the types with `|`.
|
|
|
|
The description for `Function` type arguments should make it clear how it may be
|
|
called and list the types of the parameters that will be passed to it.
|
|
|
|
#### Platform-specific functionality
|
|
|
|
If an argument or a method is unique to certain platforms, those platforms are
|
|
denoted using a space-delimited italicized list following the datatype. Values
|
|
can be `macOS`, `Windows` or `Linux`.
|
|
|
|
```markdown
|
|
* `animate` boolean (optional) _macOS_ _Windows_ - Animate the thing.
|
|
```
|
|
|
|
### Events
|
|
|
|
The events chapter must be in following form:
|
|
|
|
```markdown
|
|
### Event: 'wake-up'
|
|
|
|
Returns:
|
|
|
|
* `time` string
|
|
|
|
...
|
|
```
|
|
|
|
The heading can be `###` or `####`-levels depending on whether the event
|
|
belongs to a module or a class.
|
|
|
|
The arguments of an event follow the same rules as methods.
|
|
|
|
### Properties
|
|
|
|
The properties chapter must be in following form:
|
|
|
|
```markdown
|
|
### session.defaultSession
|
|
|
|
...
|
|
```
|
|
|
|
The heading can be `###` or `####`-levels depending on whether the property
|
|
belongs to a module or a class.
