- Use for search:
- Normal search: Match the string given in the Search field
- Wildcards: The string can contain the wildcard characters
- ? (single character)
- * (any group of characters)
- Regular expression: The search string is interpreted as a MySQL regular expression, except some regular expressions, that are black-listed for technical reasons.
- Please see the MySQL regular expression documentation for details on how to use regular expressions
The following table illustrates some commonly used metacharacters and constructs in a regular expression, that are allowed to use in translate5:
Metacharacter Behavior ^ matches the position at the beginning of the searched string $ matches the position at the end of the searched string […] matches any character specified inside the square brackets [^…] matches any character not specified inside the square brackets * matches the preceding character zero or more times + matches preceding character one or more times {n} matches n number of instances of the preceding character {m,n} matches from m to n number of instances of the preceding character The following list contains the regular expressions and regular expressions search string validation patterns , which are not supported by translate5, because they are black-listed:
Regex Description Refex Description \x[a-fA-F0-9]{2} Hexadecimal escape | \xFF where FF are 2 hexadecimal digits | Matches the character at the specified position in the code page | \xA9 matches © when using the Latin-1 code page\n Character escape \r Character escape \t Character escape \f Character escape \v Character escape c[a-zA-Z] Control character escape \cA through \cZ Match an ASCII character Control+A through Control+Z, equivalent to \x01 through \x1A \cM\cJ matches a Windows CRLF line break. Control character escape \ca through \cz Match an ASCII character Control+A through Control+Z, equivalent to \x01 through \x1A \cm\cj matches a Windows CRLF line break \0 NULL escape \(?:[1-7][0-7]{0,2}|[0-7]{2,3})1 or \2 etc. Octal escape (Any character with a character code lower than 256 ex: \251)(.*)\|(.*) javascript: a|ab matches a in ab | In POSIX ERE: a|ab matches ab in ab Some Characters | Some Characters Using | for and "or" regex \^ or \] or \- or \\\\[\^\]\-] \ (backslash) followed by any of ^-]\ \b javascript: [\b\t] matches a backspace or a tab character. \B javascript: \B. matches b, c, e, and f in abc def \d Shorthand Character Classes \D Shorthand Character Classes \s Shorthand Character Classes \S Shorthand Character Classes \w Shorthand Character Classes \W Shorthand Character Classes \h Shorthand Character Classes \?\? e. g. a regular expression like abc?? matches ab or abc \*\? ".*?" matches "def" and "ghi" in abc "def" "ghi" jkl \+\? ".+?" matches "def" and "ghi" in abc "def" "ghi" jkl {[0-9],[0-9]}\? {1,1}? Matches exactly one time (meaningless quantifier) {[0-9],}\? Matches between one and unlimited times, as few times as possible, expanding as needed \u[a-fA-F0-9]{4} Specific Unicode code points can not be searched with regular expressions. The code point shown here is an example. ex: \u78af \(\?\:.*?\) Non-capturing parentheses group the regex so you can apply regex operators, but do not capture anything. \(.*?\)=\\[0-9] (abc|def)=\1 matches abc=abc or def=def, but not abc=def or def=abc. \(\?\=.*?\) Matches at a position where the pattern inside the lookahead can be matched. Matches only the position. It does not consume any characters or expand the match. In a pattern like one(?=two)three, both two and three have to match at the position where the match of one ends. \(\?\!.*?\) Similar to positive lookahead, except that negative lookahead only succeeds if the regex inside the lookahead fails to match. \[\:(.*)\:\] This regex will validate if the user enters '[:(.*):]' The following table illustrates some commonly used metacharacters and constructs in a regular expression.
Metacharacter Behavior ^ matches the position at the beginning of the searched string $ matches the position at the end of the searched string […] matches any character specified inside the square brackets [^…] matches any character not specified inside the square brackets * matches the preceding character zero or more times + matches preceding character one or more times {n} matches n number of instances of the preceding character {m,n} matches from m to n number of instances of the preceding character is not supported. *? +? OTHERS Other regular expressions, that are similar to the listed expressions are also not supported. The front-end of translate5 will tell you, if a regex is not supported. Please contact translate5 lead development at MittagQI, if you have more questions about this.
- Save segment on close: If checked (by default yes), the segment will be saved when is closed via search navigation
- Search on locked segments: If checked, segments that are locked for editing are searched, too.
