Lowercased - Usage - Computers

Computers

Some sentence cases are not used in standard English, but are common in computer programming, as well as in product branding and in other specialised fields:

• CamelCase: First letter of each word is capitalized, spaces and punctuation removed. If the very first letter is capitalized, as in "CamelCase" (or "PowerPoint"), the term "upper camel case" may be used; this is also known as "Pascal case" or "Bumpy case". "Lower camel case" describes a variation, as in "camelCase" (or "iPod" or "eBay"), in which the very first letter is in lower case.
• Start case: First letter of each word capitalized, spaces separate words. All words including short articles and prepositions start with a capital letter. For example: "This Is A Start Case".
• Snake_case: punctuation is removed and spaces are replaced by single underscores. Normally the letters share the same case (either UPPER_CASE_EMBEDDED_UNDERSCORE or lower_case_embedded_underscore) but the case can be mixed.
• spinal-case or Train-Case: similar to snake_case, but spaces are replaced by dashes, instead of underscores.
• Studly caps: Mixed case, as in "StUdLyCaPs", with no semantic or syntactic significance to the use of the capitals. Sometimes only vowels are upper-case, at other times upper and lower case are alternated, but often it is just random. The name comes from the sarcastic or ironic implication that it was used in an attempt by the writer to convey their own coolness. (It is also used to mock the violation of standard English case conventions by marketers in the naming of computer software packages, even when there is no technical requirement to do so—e.g., Sun Microsystems' naming of a windowing system NeWS.)
