Ultraedit macro examples8/31/2023 ![]() ![]() You can see all available character class names below, or on Boost's Perl library online documentation. Character classes: An expression of the form ] matches the named character class "name", for example ] matches any lower case character.Negation: If the bracket-expression begins with the ^ character, then it matches the complement of the characters it contains, for example matches any character that is not in the range "a-c".By default, for POSIX-Perl regular expressions, character "x" is within the range "y to z", if it collates within that range this results in locale specific behavior. Character ranges: For example will match any single character in the range "a" to "c'.Single characters: For example, will match any of the characters "a", "b", or "c".This bracketed expression may contain any combination of the following: (?:)|abc is and is equivalent, also the expression:Ī character set is a bracketed expression starting with which defines a set of characters, and matches any single character that is a member of that set.Empty alternatives are not allowed (these are almost always a mistake), but if you really want an empty alternative use (?:) as a placeholder, for example: Parenthesis can be used to group alternations, for example: ab(d|ef) will match either of "abd" or "abef". The | operator will match either of its arguments, so for example: abc|def will match either "abc" or "def". Marked sub-expressions can also be repeated or referred to by a backreference. Whatever matches this sub-expression is split into a separate field by the matching algorithms. For example dog|cat would match both "dog" and "cat"Ī section beginning with a ( and ending with a ) is a marked sub-expression. Tags the enclosed atom for backreferencing For example would match a, b, c, and d – but not e. ![]() Matches any single character except new lines In Perl regular expressions, all characters match themselves except for the following special characters: Note: in the following documentation, atom may refer to a single character, a marked sub-expression, or a character class. With a final search downwards for a non whitespace character and moving character back the caret is finally positioned on first non whitespace character after a whitespace character.UltraEdit supports Perl style regular expressions for search using the Boost C++ Libraries. Then a search upwards for a whitespace character is processed to move caret to the position before beginning of this non whitespace string. If caret was originally positioned on a whitespace character or first non whitespace character after a whitespace character, a search upwards for a non whitespace character is processed to move caret to last non whitespace character of previous string. I have currently no solution for this special problem. Please note that this does not work on soft wrapped lines as when caret is currently positioned on first word of a soft wrapped line moving caret one character to left results in moving the caret to end of the soft wrapped line above but is positioned there still one same character as before at beginning of the soft wrapped line below. If the character to left of original position is not a whitespace (with the exception of non breaking space and some other rare whitespaces), the caret was originally within a string of non whitespace characters and must be therefore moved upwards to the first character of this string. If caret is currently positioned on a character which has a code value greater than 32 (a space character) and is therefore not a control character or whitespace character (with the exception of non breaking space and some other rare whitespaces), move character one character to the left. Moving caret upwards to first character after a whitespace character is more difficult as it must be distinguished if the caret is currently already on first character after a whitespace character or anywhere inside a string of non whitespace characters. The second macro is (nearly) like Ctrl+Left Arrow with the difference that it treats every non whitespace character as word character and not just letters, digits and underscores. Then search downwards for next non whitespace character and move caret back 1 character if indeed found. If not found up to end of file, move caret to end of file. If caret is currently positioned on a character which has a code value greater than 32 (a space character) and is therefore not a control character or whitespace character (with the exception of non breaking space and some other rare whitespaces), find downwards 1 or more whitespace characters. ![]()
