Advanced Search function of ultraedit

In addition to using the IDE to edit code, programmers often use lightweight editors, such as ultraedit and notepad ++. Among these editors, we often use the "Search" function ", "Replace ". These software provides a variety of search replacement functions, and even provides regular expressions to assist in search replacement. The following table lists the regular expression syntax of UE.

Regular Expression (ultraedit syntax ):

Symbol	Function
%	Match the first line-indicates that the search string must start with the line, but does not include the row termination characters in any selected result characters.
$	Match the end of a line-indicates that the search string must be at the end of the line, but does not include the end of the line in any selected result character.
?	Match any character except the line break.
*	Match any number of characters except line breaks.
+	Match one or more previous characters/expressions. At least one character must be found. Duplicate line breaks are not matched.
++	Matches the previous character/expression zero or multiple times. Duplicate line breaks are not matched.
^ B	Match a paging character.
^ P	Match a line break (CR/LF) (Section) (DOS file)
^ R	Match a line break (CR only) (Section) (MAC file)
^ N	Match A linefeed (lf only) (Section) (UNIX file)
^ T	Match a tab
[]	Match a single character or range in any parentheses
^ {A ^} ^ {B ^}	Matching expression A or B
^	Ignore the subsequent regular expression characters
^ (* ^)	Add parentheses or tags to the expression and use them in the replacement command. There can be 9 expression tags in a regular expression, and numbers are determined based on their order in the regular expression. The corresponding replacement expression is ^ X, and the range of X is 1-9. For example, if ^ (H * o ^) ^ (F * s ^) matches "Hello folks", ^ 2 ^ 1 indicates that it will be replaced with "Folks hello.

For example:

M? N matches "man", "men", and "min", but does not match "moon ".

T * t matches "Tea t" in "test", "tonight", and "tea time", but does not match "tea"

Time (there is a line break between "tea" and "time ).

Te + st matches "test", "teest", and "teeeest", but does not match "TST ".

[Aeiou] matches each vowel in lower case

[,.?] Match the text ",", ".", or "?".

[0-9a-z] matches any number or lowercase letter

[~ 0-9] match any character except a number (~ Does not match the subsequent content)

Example:

1. Search for rows starting with a specified string
% Yourstring
2. Delete the row ending with the specified string
Yourstring $
3. Delete space rows
Search: ^ p $
Replace with: NULL
4. Delete rows containing specific strings
Search: % * your string * ^ P
Replace with: NULL

In addition, if the regular expression is not selected in search/replace, the following special characters in the replace object are also valid:

Symbol	Function
^	Match the character "^"
^ S	Indicates the selected (highlighted) text in the activity file window.
^ C	The content of the clipboard table.
^ B	Match a paging character.
^ P	Match a line break (CR/LF) (Section) (DOS file)
^ R	Match a line break (CR only) (Section) (MAC file)
^ N	Match A linefeed (lf only) (Section) (UNIX file)
^ T	Match a tab
