Google have published a style guide for their developers.
It’s a nice guide for all writers of non-fiction.
Some cute things:
On semicolons (I never know when to use) not much help (https://developers.google.com/style/semicolons)
Where to use semicolons is often a matter of judgment. Use them judiciously.
In the resources section the style guide refers to Apple’s and Microsoft’s style guides. (https://developers.google.com/style/resources)
Other companies’ style guides, such as the Apple Style Guide or the Microsoft Manual of Style.
Anthropomorphisms, which I like especially in documentation (makes them read like a novel, if done well), however not recommended by Google (https://developers.google.com/style/anthropomorphism):
Examples
Not recommended: A Delimiter object tells the splitter where a string should be broken.
Recommended: A Delimiter object specifies where to split a string.
Just one I did not understand (https://developers.google.com/style/headings):
Things to avoid in headings
Don’t use the following in headings:
- Code font.
- API levels for Android versions.
Enjoyable.
