SlickEdit Regular Expression

 

Definition

 

 

 

 

 

avoid ambiguous expressions. For example a:9()1

 

 

searches for nine instance of the letter a followed

 

 

by a 1.

X:n1,

 

Maximal match of at least n1 occurrences of X.

 

 

 

X:n1,n2

 

Maximal match of at least n1 occurrences but not

 

 

more than n2 occurrences of X.

 

 

 

X:*n1,

 

Minimal match of at least n1 occurrences of X.

 

 

 

X:*n1,n2

 

Minimal match of at least n1 occurrences but not

 

 

more than n2 occurrences of X.

~X

 

Search fails if expression X is matched. The ex-

 

 

pression ^~(if) matches the beginning of all lines

 

 

that do not start with if.

(X)

 

Matches sub-expression X.

 

 

 

{X}

 

Matches sub-expression X and specifies a new

 

 

tagged expression. See Using Tagged Search Ex-

 

 

pressions for more information.

 

 

 

{#dX}

 

Matches sub-expression X and specifies to use

 

 

tagged expression number d where 0<=d<=9.

XY

 

Matches X or Y.

 

 

 

[char-set]

 

Matches any one of the characters specified by

 

 

char-set. A dash (-) character may be used to

 

 

specify ranges. The expression [A-Z]matches any

 

 

uppercase letter. Backslash (\) may be used inside

 

 

the square brackets to define literal characters or

 

 

define ASCII characters. For example, \- specifies a

 

 

literal dash character. The expression [\0-\27]

 

 

matches ASCII character codes 0..27. The expres-

 

 

sion [] matches no characters. In UNIX regular ex-

 

 

pressions, []] matches a right bracket. In both syn-

 

 

taxes, the expression [\]] matches a right bracket.

 

 

The expression [\^] matches a caret (^) character in

 

 

both syntaxes.

 

 

 

[~char-set]

 

Matches any character not specified by char-set.

 

 

A dash (-) character may be used to specify ranges.
