How to surround code by curly braces in IntelliJ IDEA? Is there any keyboard-shortcut for such operation? zagyi Yes, try Ctrl + Alt + T (Surround With), then A (Curly Braces). Ajang R Just configure Smart Keys as follow: IDE Settings > Editor > General > Smart Keys > Surround selection on typing quote or brace . From the IntelliJ built-in help: If this check box is selected , the selected text on typing a quote, double-quote or brace, will be surrounded with these characters. If this check box is not selected , then the typed quotes, double-quotes or braces will replace the selection. Just

In Visual Studio while designing MVC views (in .aspx or .ascx files) I often use if statements. When I auto-format (Ctrl-K,D), VS wraps the braces in this really ugly and hard to read way: <% if (Model.UserIsAuthenticated) { %> (some HTML goes here...) <% } %> Is there any way to make Visual Studio auto-format like this instead: <% if (Model.UserIsAuthenticated) { %> (some HTML goes here...) <% } %> Or is there a better way to do this? I don't want to use Razor quite yet, but it looks like it would solve my problem. I'm using VS2010 with Resharper 5, if that helps. felixmm Under Tools →

Usually, bash functions are defined using curly braces to enclose the body: foo() { ... } When working on a shell script today making extensive use of functions, I've run into problems with variables that have the same name in the called as in the calling function, namely that those variables are the same. I've then found out that this can be prevented by defining the local variables inside the function as local: local var=xyz . Then, at some point, I've discovered a thread ( Defining bash function body using parenthesis instead of braces ) in which it is explained that it's just as valid to

I love short if statements without braces (PHP) like if ($x === $y) echo $z; If I want to add a few lines (maybe just temporary for debugging) I have to manually add the braces. Is there a plugin for netbeans that does that via shortcut, something like "toggle (add/remove) previous statement braces"? The best solution I got for now are two macros Add Curly-Braces: caret-end-line caret-begin-line "{" insert-break Remove Curly-Braces: caret-up caret-end-line remove-word-next selection-match-brace cut-to-clipboard remove-line remove-word-previous insert-break paste-from-clipboard caret-up caret

I wonder why this two following codes give different results; for(i = 1, j = 0; i < 10; i++) { j += i; System.out.println(i); } This one gives the numbers between 1 included and 10 excluded. for(i = 1, j = 0; i < 10; i++) j += i; System.out.println(i); However this one gives 10. I could not get the logic of this; for() do_something; do_something_else; That is because the default scope of an iteration in your case is the only line following it, something equivalent to - for(i=1, j=0;i<10;i++) { j += i; } System.out.println(i); Hence the entire loop is iterated and since after that the value of

I know {} are used to separate entities such as functions, classes and conditional branching, but what other use would they have here? #import <stdio.h> int main(void) { {{{ printf("main\n"); }}} return 0; } EDIT: I found that it may be useful primarily for information hiding, along with nested functions . From the answers below it would seem they can be used as a marker during debugging and be removed in the release, but that this should not be endorsed. Enclosing a code in braces { } creates an Scope . Creating an local scope can have number of reasons like: Allows you to reuse a variable

Using ruby 1.9.2-p290. I came across an issue trying to parse a URI like the following: require 'uri' my_uri = "http://www.anyserver.com/getdata?anyparameter={330C-B5A2}" the_uri = URI.parse(my_uri) issuing the following error: URI::InvalidURIError: bad URI(is not URI?) I require a different solution than encoding the curly braces every time like this: new_uri = URI.encode("http://www.anyserver.com/getdata?anyparameter={330C-B5A2}") => "http://www.anyserver.com/getdata?anyparameter=%7B330C-B5A2%7D" Now I can parse the new_uri as usual, but had to do this every time I needed it. What is the

Possible Duplicate: How to access object properties with names like integers? print_r($myObj) gives the following result: stdClass Object ( [4021450] => stdClass Object ( [property1] => ooo [property2] => xxx ) [3971601] => stdClass Object ( [property1] => 123 [property2] => 356 ) ) How can I using the curly brace syntax with variable to access the sub-object ?
