Regex for Eclipse/Flash Builder File Search for comments?

In Eclipse (and Flash/Flex Builder) you get the option with Ctrl+Shift+F to do a f开发者_如何学运维ile search and look for a regular expression. Would be a real handy thing to know.

I want to find the word negate if it appears in a Flex/java comment like the following:

// It was negated because

or

/*
  The negate option was....
*/

or

/**
 * We have to negate the value
*/

Any ideas? Will test them out at http://www.regexplanet.com/simple/index.html

Matching only the word "negate" is tricky, because you would need a lookbehind expression (such as (?<=\/\/.*)negate to match only "negate"s preceded by // and any number of characters), but these are supposed to have a fixed length - which we cannot know, since "negate" could really appear anywhere inside a comment. I'm afraid I don't know any other way to match single words inside other text.

However, you can find entire comments containing "negate" in eclipse using this RegEx:

((//.*negate.*$)|(/\*(.|\r|\n)*negate(.|\r|\n)*\*/))

Edit: removed some unnecessary backslashes

This should do it for you I believe:

(?://.|/*.\s*.*)negate
