Example
Description
UNIX regular expression:
Search for:
(if|while)
Replace with:
x\1y\2
SlickEdit
®
regular expression:
Search for:
{if|while}
Replace with:
x#0y#1
Brief regular expression:
Search for:
{{if}|while}}
Replace with:
x\0y\1
Replace occurrences of "if" and "while" with "xify"
and "xwhiley." Unmatched groups are null. Note:
The UNIX syntax
\2
(SlickEdit syntax
#1
, Brief syn-
tax
\1
) is replaced with null.
UNIX regular expression:
Search for:
^(.*?),(.*)$
Replace with:
\2,\1
SlickEdit regular expression:
Search for:
^{?*},{?*}$
Replace with:
#1,#0
Brief regular expression:
Search for:
^{*},{*}$
Replace with:
\1,\0
Reverse text on lines containing a comma. Lines
with "abc,def" will be changed to "def,abc." Notice
that the UNIX regular expression search string uses
a minimal matching operator
*?
so that the comma
actually matches the first comma in the line and not
the last.
Minimal versus Maximal Matching
If you are using tagged expressions or regular expressions to perform a search and replace, you need to
understand the difference between the minimal and maximal operators.
Take, for example, a line of text which contains a DOS file name:
\path1\path2\path3\name.ext
.
The regular expression
^\\.*?\\
(UNIX),
^\\?*\\
(SlickEdit
®
), or
<\\*\\
(Brief) will match the string
\path1\
.
The regular expression
^\\.*\\
(UNIX),
^\\?@\\
(SlickEdit), or
<\\\:*\\
(Brief), which uses the maximal oper-
ator, matches the string
\path\path2\path3\
.
As a rule of thumb, you will usually want to use the minimal matching operators
*?
(UNIX),
*
(SlickEdit), or
@
(Brief) and
+?
(UNIX),
+
(SlickEdit/Brief) after a less-specific regular expression such as
.
(UNIX) or
?
(SlickEdit/Brief).
You will usually want to use the maximal matching operators after a regular expression which matches
something more specific. For example, to search for a string of digits and prefix each string of digits with
the character
$
, you would specify the following in the
Replace
tab of the Find and Replace view:
•
UNIX regular expression:
Search for:
([0-9]+)
Replace with:
$\1
