New page

In addition to [[Perl regular expressions]], UltraEdit supports two other "legacy" styles: a proprietary regular expression syntax and a basic Unix syntax. We typically recommend using Perl regular expressions, as these are far more powerful and robust than these two legacy styles.

==UltraEdit (legacy) style syntax==

{|
!Symbol
!Function
|-
|%
|Matches the start of line - Indicates the search string must be at the beginning of a line but does not include any line terminator characters in the resulting string selected.
|-
|$
|Matches the end of line - Indicates the search string must be at the end of line but does not include any line terminator characters in the resulting string selected.
|-
|?
|Matches any single character except newline.
|-
|*
|Matches any number of occurrences of any character except newline. At least one occurrence of the preceding character or one of the characters in preceding character set must be found.
|-
|<nowiki>+</nowiki>
|Matches one or more of the preceding single character/character set. At least one occurrence of the character must be found.
|-
|<nowiki>++</nowiki>
|Matches the preceding single character/character set zero or more times.
|-
|^b
|Matches a page break.
|-
|^p
|Matches a newline (CR/LF) (paragraph) (DOS Files)
|-
|^r
|Matches a newline (CR Only) (paragraph) (MAC Files)
|-
|^n
|Matches a newline (LF Only) (paragraph) (UNIX Files)
|-
|^t
|Matches a tab character
|-
|<nowiki>[xyz]</nowiki>
|A character set. Matches any characters between brackets.
|-
|<nowiki>[~xyz]</nowiki>
|A negative character set. Matches any characters NOT between brackets including newline characters.
|-
|^{A^}^{B^}
|Matches expression A OR B
|-
|^
|Overrides the following regular expression character
|-
|^(...^)
|Brackets or tags an expression to use in the replace command. A regular expression may have up to 9 tagged expressions, numbered according to their order in the regular expression.

The corresponding replacement expression is ^x, for x in the range 1-9. Example: If ^(h*o^) ^(f*s^) matches "hello folks", ^2 ^1 would replace it with "folks hello".
|}

Note: ^ refers to the character '^' , not the Ctrl key.

Examples:

{|
|m?n
|matches "man", "men", "min" but not "moon".
|-
|t*t
|matches "test", "tonight" and "tea time" (the "tea t" portion) but not "tea time" (newline between "tea " and "time").
|-
|Te+st
|matches "test", "teest", "teeeest" etc. but does not match "tst".
|-
|[aeiou]
|matches every lowercase vowel
|-
|[,.?]
|matches a literal ",", "." or "?".
|-
|[0-9a-z]
|matches any digit, or lowercase letter
|-
|[~0-9]
|matches any character except a digit (~ means NOT the following)
|}

You may search for an expression A or B as follows:

"^{John^}^{Tom^}"

This will search for an occurrence of John or Tom. There should be nothing between the two expressions.

You may combine A or B and C or D in the same search as follows:

"^{John^}^{Tom^} ^{Smith^}^{Jones^}"

This will search for John or Tom followed by Smith or Jones.

==Unix (legacy) style syntax==

{|
!Symbol
!Function
|-
|\
|Indicates the next character has a special meaning. "n" on it's own matches the character "n". "\n" matches a linefeed or newline character. See examples below (\d, \f, \n etc).
|-
|^
|Matches/anchors the beginning of line.
|-
|$
|Matches/anchors the end of line.
|-
|*
|Matches the preceding single character/character set zero or more times.
|-
|<nowiki>+</nowiki>
|Matches one or more of the preceding single character/character set. At least one occurrence of the preceding character or one of the characters in preceding character set must be found.
|-
|.
|Matches any single character except a newline character. Does not match repeated newlines.
|-
|(expression)
|Brackets or tags an expression to use in the replace command. A regular expression may have up to 9 tagged expressions, numbered according to their order in the regular expression.

The corresponding replacement expression is \x, for x in the range 1-9. Example: If (h.*o) (f.*s) matches "hello folks", \2 \1 would replace it with "folks hello".
|-
|[xyz]
|A character set. Matches any characters between brackets.
|-
|[^xyz]
|A negative character set. Matches any characters NOT between brackets including newline characters.
|-
|\d
|Matches a digit character. Equivalent to [0-9].
|-
|\D
|Matches a nondigit character. Equivalent to [^0-9].
|-
|\f
|Matches a form-feed character.
|-
|\n
|Matches a linefeed character.
|-
|\r
|Matches a carriage return character.
|-
|\s
|Matches any whitespace including space, tab, form-feed, etc but not newline.
|-
|\S
|Matches any non-whitespace character but not newline.
|-
|\t
|Matches a tab character.
|-
|\v
|Matches a vertical tab character.
|-
|\w
|Matches any alphanumeric character including underscore.
|-
|\W
|Matches any character except alphanumeric characters and underscore.
|-
|\p
|Matches CR/LF (same as \r\n) to match a DOS line terminator.
|}

Note: ^ refers to the character '^' , not the Ctrl key.

Examples:

{|
|m.n
|matches "man", "men", "min" but not "moon".
|-
|Te+st
|matches "test", "teest", "teeeest" etc. BUT NOT "tst".
|-
|Te*st
|matches "test", "teest", "teeeest" etc. AND "tst".
|-
|<nowiki>[aeiou]</nowiki>
|matches every lowercase vowel
|-
|<nowiki>[,.?]</nowiki>
|matches a literal ",", "." or "?".
|-
|<nowiki>[0-9a-z]</nowiki>
|matches any digit, or lowercase letter
|-
|<nowiki>[^0-9]</nowiki>
|matches any character except a digit (^ means NOT the following)
|}

You may search for an expression A or B as follows:

"(John|Tom)"

This will search for an occurrence of John or Tom. There should be nothing between the two expressions.

You may combine A or B and C or D in the same search as follows:

"(John|Tom) (Smith|Jones)"

This will search for John or Tom followed by Smith or Jones.

If regular expressions aren't enabled for a find/replace, the following special characters are also valid in the Find and Replace fields:

{|
!Notation
!Represents
|-
|^t
|Tab character
|-
|^p
|New line (DOS files - CR/LF, or hex 0D 0A)
|-
|^r
|Carriage return (hex 0D)
|-
|^n
|Line feed (new line in Unix based text files) (hex 0A)
|-
|^b
|Line break
|-
|^s
|Selected text
|-
|^c
|Clipboard contents (up to 30,000 characters)
|-
|^^
|Literal "^" character
