Most special characters lose their meaning and represent ordinary characters when they occur inside a bracket expression. For more information, see "Characters in Bracket Expressions" inLists of Matching Charac
In JavaScript 1.5(but not JavaScript 1.2), it is possible to group items in a regular expression without creating a numbered reference to those items. Instead of simply grouping the items within(and), begin the group with(?:and end it with). Consider the following pattern, for example: /(...
(meaning it will move to the right), you set the X property to 2. To move it to the left, use a negative value, such as -2. Similarly, to move an object vertically, you would use the Y property, and positive values will cause the object to move down the screen, whereas negative...
One of the principal design goals of Algol 68 was to make the various features of the language asorthogonalas possible.Orthogonalitymeans that features can be used in any combination, the combinations all make sense, and the meaning of a given feature isconsistent, regardless of the other featur...
<(.|\n)+?> How can I remove all blank lines from a string using regular expression? Make sure to be in global and multiline mode. Use an empty string as a replacement value. ^\s*\r?\n
The body of the preceding <c:if> action is evaluated if the emailAddress request parameter is not empty, meaning neither null nor an empty string. If you're using JSTL with JSP 1.2, you can only use JSTL expressions to specify values for JSTL action attributes, as illustrated above.3 All...
Also, the AEC-to-WebAssembly compiler supports the operators +=, -=, *= and /=, with the same meaning as they have in C. For example, the following code in the x86 dialect of AEC: i := 0 While i < n | i = n If i = 0 fib(i) := 0 ElseIf i = 1 fib(i) := 1 ...

JavaScript: Regular Expressions patterns Sometimes various pattern matching is required instead of direct matching. For example, the pattern /xy*z/ matches any character. For example, /bo*/ matches 'boo' in "A book" and 'b' in "A beautiful river", but nothing in "A going concern". ...
