| 62 | In this minor mode, a word boundary occurs immediately before an | ||
| 63 | uppercase letter in a symbol. This is in addition to all the normal | ||
| 64 | boundaries given by the syntax and category tables. There is no | ||
| 65 | restriction to ASCII. | ||
| 66 | |||
| 67 | E.g. the beginning of words in the following identifier are as marked: | ||
| 68 | |||
| 69 | capitalizedWorDD | ||
| 70 | ^ ^ ^^ | ||
| 71 | |||
| 72 | Note that these word boundaries only apply for word motion and | ||
| 73 | marking commands such as \\[forward-word]. This mode does not affect word | ||
| 74 | boundaries in found by regexp matching (`\\>', `\\w' &c). | ||
| 75 | |||
| 76 | This style of identifiers is common in environments like Java ones, | ||
| 77 | where underscores aren't trendy enough. Capitalization rules are | ||
| 78 | sometimes part of the language, e.g. Haskell, which may encourage such | ||
| 79 | a style. It is appropriate to add `capitalized-words-mode' to the | ||
| 80 | mode hook for programming langauge modes in which you encounter such | ||
| 81 | variables, e.g. `java-mode-hook', since it's unlikely to cause trouble | ||
| 82 | if such identifiers aren't used. | ||
