Text Capitalization

These rules apply for text rendered to the user (e.g. GUI labels, console output, etc.). CamelCase is forbidden, except if you use a proper name that is already in camel case, like OpenWalnut, OpenSceneGraph, etc. Furthermore, there are two styles of capitalization used in OpenWalnut user interface elements:

Header capitalization

Capitalize all words in the element, with the following exceptions:

Articles: a, an, the
Conjunctions: and, but, for, not, so, yet etc.
Prepositions of three or fewer letters: at, for, by, in, to etc.

The following are explicitly no exceptions:

The second part of a word with a dash: Add-On, Auto-Display, Multi-Threaded etc.

Sentence capitalization

Capitalize the first letter of the first word, and any other words normally capitalized in sentences, such as application names.
