New review: owner: dougkearns I like this for the most part, except that it has to go to lengths to wrap the original nsIFile correctly, an that it can't be passed directly to other XPCOM components. It makes most operations on files a lot cleaner, though.

// There are three types of abbreviations:
|
|
//
|
|
// full-id: Consists entirely of keyword characters.
|
|
// ("foo", "g3", "-1")
|
|
//
|
|
// end-id: Ends in a keyword character, but all other
|
|
// are not keyword characters.
|
|
// ("#i", "..f", "$/7")
|
|
//
|
|
// non-id: Ends in a non-keyword character, but the
|
|
// others can be of any type other than space
|
|
// and tab.
|
|
// ("def#", "4/7$")
|
|
//
|
|
// Example strings that cannot be abbreviations:
|
|
// "a.b", "#def", "a b", "_$r"
|
|
//
|
|
// For now, a keyword character is anything except for \s, ", or '
|
|
// (i.e., whitespace and quotes). In Vim, a keyword character is
|
|
// specified by the 'iskeyword' setting and is a much less inclusive
|
|
// list.
|

// definition (which differs across platforms).
