Regular Expressions with BRIEF Emulation

Home Page (Text Editor) |  Overview |  How Do I ... Topics |  FAQ |  Reference

?Any single character.

[ ]Any one of the characters contained in the brackets, or any of an ASCII range of characters separated by a hyphen (-). For example, b[aeiou]d matches bad, bed, bid, bod, and bud, and r[eo]+d matches red, rod, reed, and rood, but not reod or roed. For numbers, x[0-9] matches x0, x1, x2, and so on. If the first character in the brackets is a tilde (~), then the regular expression matches any characters except those in the brackets.

%The beginning of a line.

$The end of a line.

{ }Indicates a tagged expression to retain for replacement purposes. If the expression in the Find What text box is {lpsz}BigPointer, and the expression in the Replace With box is \0NewPointer, all selected occurrences of lpszBigPointer are replaced with lpszNewPointer. Each occurrence of a tagged expression is numbered according to its order in the Find What text box, and its replacement expression is \n, where 0 corresponds to the first tagged expression, 1 to the second, and so on. You can have up to ten tagged expressions.

~Not the following character. For example, b~ad matches bbd, bcd, bdd, and so on, but not bad.

{c|c}Any one of the characters separated by the alternation symbol (|). For example, {j|u}+fruit finds jfruit, jjfruit, ufruit, ujfruit, uufruit, and so on.

@None or more of the preceding characters or expressions. For example, ba@c matches bc, bac, baac, baaac, and so on.

+At least one or more of the preceding characters or expressions. For example, ba+c matches bac, baac, and baaac, but not bc.

[ ]
Any sequence of characters between the brackets. For example, [ju]+fruit finds jufruit, jujufruit, jujujufruit, and so on. Note that it will not find jfruit, ufruit, or ujfruit because the sequence ju is not in any of those strings.

[~]
Any character except those following the tilde character (~) in the brackets, or any of an ASCII range of characters separated by a hyphen (-). For example, x[~0-9] matches xa, xb, xc, and so on, but not x0, x1, x2, and so on.

[a-zA-Z0-9]Any single alphanumeric character.

[\x09\]+Any white-space character.

[a-zA-Z]Any single alphabetic character.

[0-9]Any decimal digit.

[0-9a-fA-F]+Any hexadecimal number.

{[0-9]+.[0-9]@}|{[0-9]@.[0-9]+}|{[0-9]+}Any unsigned number. For example,
{[0-9]+.[0-9]@}|{[0-9]@.[0-9]+}|{[0-9]+} should match 123, .45, and 123.45.

[0-9]+Any unsigned decimal integer.

[a-zA-Z_$][a-zA-Z0-9_$]@C/C++ identifier.

[a-zA-Z]+Any English word (that is, any string of alphabetic characters).

"[~"]@"Any quoted string.

\Removes the pattern match characteristic in the Find What text box from the special characters listed above. For example, 100$ matches 100 at the end of a line, but 100\$ matches the character string 100$ anywhere on a line.
