_Select first_ the text you want to format and then press &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;I&lt;/kbd&gt;.

Use &lt;kbd&gt;Cmd&lt;/kbd&gt;+&lt;kbd&gt;A&lt;/kbd&gt; first if you wish to format all text in the selected file.

**Note**: this procedure only re-indents the lines, it does _not_ do any advanced formatting.

I would suggest taking a look JetBrains AppCode IDE. It has a Reformat Code command. I have come from a C# background and used Visual Studio with Jetbrains Resharper plugin, so learning AppCode has been a pleasure because many of the features in Resharper also exist in AppCode!

Theres too many features to list here but could well be worth checking out

I&#39;m in the research phase trying to adopt 2012 Database Projects on an existing small project. I&#39;m a C# developer, not a DBA, so I&#39;m not particularly fluent with best practices. I&#39;ve been searching google and stackoverflow for a few hours now but I still don&#39;t know how to handle some key deployment scenarios properly.

1) Over the course of several development cycles, how do I manage multiple versions of my database? If I have a client on v3 of my database and I want to upgrade them to v8, how do I manage this? We currently manage hand-crafted schema and data migration scripts for every version of our product. Do we still need to do this separately or is there something in the new paradigm that supports or replaces this?

2) If the schema changes in such a way that requires data to be moved around, what is the best way to handle this? I assume some work goes in the Pre-Deployment script to preserve the data and then the Post-Deploy script puts it back in the right place. Is that the way of it or is there something better?

3) Any other advice or guidance on how best to work with these new technologies is also greately appreciated!

**UPDATE:** My understanding of the problem has grown a little since I originally asked this question and while I came up with a workable solution, it wasn&#39;t quite the solution I was hoping for. Here&#39;s a rewording of my problem:

The problem I&#39;m having is purely data related. If I have a client on version 1 of my application and I want to upgrade them to version 5 of my application, I would have no problems doing so if their database had no data. I&#39;d simply let SSDT intelligently compare schemas and migrate the database in one shot. Unfortunately clients have data so it&#39;s not that simple. Schema changes from version 1 of my application to version 2 to version 3 (etc) all impact data. My current strategy for managing data requires I maintain a script for each version upgrade (1 to 2, 2 to 3, etc). This prevents me from going straight from version 1 of my application to version 5 because I have no data migration script to go straight there. The prospect creating custom upgrade scripts for every client or managing upgrade scripts to go from every version to every greater version is exponentially unmanageable. What I was hoping was that there was some sort of strategy SSDT enables that makes managing the data side of things easier, maybe even as easy as the schema side of things. My recent experience with SSDT has not given me any hope of such a strategy existing but I would love to find out differently.

In **Visual Studio**, I&#39;m seeing these warnings:

&gt; - Validation (HTML 5): Attribute &#39;cellpadding&#39; is not a valid attribute of element &#39;table&#39;.
&gt; - Validation (HTML 5): Attribute &#39;cellspacing&#39; is not a valid attribute of element &#39;table&#39;.
&gt; - Validation (HTML 5): Attribute &#39;valign&#39; is not a valid attribute of element &#39;td&#39;.
&gt; - Validation (HTML 5): Attribute &#39;align&#39; is not a valid attribute of element &#39;td&#39;.

If they are not valid attributes in **HTML5**, what replaces them in CSS?

Of all the Instruments Trace Templates, I love using:

* Zombies to detect where an object is getting over-released, great for debugging `EXEC_BAD_ACCESS` errors.
* Leaks to detect memory leaks.
* Core Animation w Color Blended Layers to detect frame rate &amp; translucent subviews, great for smoothing up `UITableView` scrolling.

I always hear people saying to profile my app&#39;s memory usage &amp; performance.

1. Why should I profile memory usage &amp; performance? My app runs fine.
2. How do I do it?

I am using ARC successfully in my project. However, I have encountered a few files (e.g., in unit tests and mock objects) where the rules of ARC are a little more fragile right now. I recall hearing that there was a way to disable ARC on a per-file basis, though I have been unable to find this option.

Is this possible? How do I disable ARC on a per-file basis?

From git I can get the timestamp:

but is there any way to show it as:

So all I want is to get rid of the -0600 timezone offset. How can I do this? Thanks.

Maybe this is a silly question, but I cannot guess how to solve it if it&#39;s not creating a method. Maybe there&#39;s a &quot;natural way&quot; to do it, like in C for example. Here&#39;s the problem:

I have a var:

    double a;

And I want to show it only with 2 or 3 decimals. When I try to show it:

    Text.setText(&quot;Value of a: &quot; + String.valueOf(a));

It gives something like:

&gt; Value of a: 5.234966145

And i would want just

&gt; Value of a: 5.23

Without changing the real value of a so it shows the approximate number but works with the real number.

After googling around, I cannot find a way to create a new table with a `DATETIME` column with the default format set to &#39;`DD-MM-YYYY HH:MM:SS`&#39;

I saw a tutorial in which it was done in `phpmyadmin` so I suspect that I could use mysql via command line and achieve the same thing when creating my new table with 

    CREATE TABLE ()

Thank you in advance

I am working on a new `Android` project (`Java`), and created an Object with a large number of variables. Since I am planning to add getters and setters for all of them, I was wondering: is there a shortcut in `Eclipse` for automatically generating the getters and setters in a given class?

Is there a way to automatically generate getters and setters in Eclipse?

Is it possible to capture these shortcuts?

  - &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;T&lt;/kbd&gt; 
  - &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;W&lt;/kbd&gt;

I tried this but it doesn&#39;t work:

    $(window).keydown(function(event) {
      console.log(event.keyCode);
      event.preventDefault();
    });

When I press &lt;kbd&gt;T&lt;/kbd&gt; it shows `84` in the console, but if I press &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;T&lt;/kbd&gt; it shows nothing, and opens a new tab.

I would like to capture these shortcuts and prevent any browser action.

I know &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;Shift&lt;/kbd&gt;+&lt;kbd&gt;Backspace&lt;/kbd&gt; is used to go to the location of the last edit.

But I want to jump to whichever location I was most recently at, not necessarily one where I edited anything.

For example, if I jumped to a declaration using &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;B&lt;/kbd&gt;, then I want to go back to where I was before jumping.

In what ways can you comment in CoffeeScript?

The documentation say you can use three hash symbols to start and close a comment block:

    ###
      Comments
      go
      here
    ###

I&#39;ve found that I can sometimes use the following two formats

    `// backticks allow for straight-JavaScript,
     // but the closing backtick can&#39;t be on a comment line (I think?)
    `

Are there a simpler way to insert short comments in CoffeeScript?

Do NOT use this style**

Since this is getting a lot of views, I want to emphasize that

    /* Comment goes here */

produces a MATH error when the `/*` is on its own line.

As Trevor pointed out in a comment on the question, this is a **regular expression**, **NOT** a comment!

I have a set of variables I allow some people I work with to edit. These are True (`T`) and False (`F`) values, but I have some people that insist on putting `t` and `f` instead of the upper case values respectively. 

I use the following workaround code to properly set uppercase values:

    IF &#39;%dotnet35%&#39;==&#39;f&#39; set dotnet35=F
    IF &#39;%dotnet35%&#39;==&#39;t&#39; set dotnet35=T
    IF &#39;%dotnet40%&#39;==&#39;f&#39; set dotnet40=F
    IF &#39;%dotnet40%&#39;==&#39;t&#39; set dotnet40=T
    IF &#39;%regedit%&#39;==&#39;f&#39; set regedit=F
    IF &#39;%regedit%&#39;==&#39;t&#39; set regedit=T
    IF &#39;%SSL%&#39;==&#39;f&#39; set SSL=F
    IF &#39;%SSL%&#39;==&#39;t&#39; set SSL=T

This is however extremely bulky and it&#39;s not easy on the eyes... is there any other way of doing this without using VBS or any other programming language?

When doing a code review for a colleague today I saw a peculiar thing. He had surrounded his new code with curly braces like this:

    Constructor::Constructor()
    {
       existing code
 
       {
          New code: do some new fancy stuff here
       }

       existing code
    }

What is the outcome, if any, from this? What could be the reason for doing this? Where does this habit come from?

**Edit:**

Based on the input and some questions below I feel that I have to add some to the question, even though that I already marked an answer.

The environment is embedded devices. There is a lot of legacy C code wrapped in C++ clothing. There are a lot of C turned C++ developers.

There are no critical sections in this part of the code. I have only seen it in this part of the code. There are no major memory allocations done, just some flags that are set, and some bit twiddling.

The code that is surrounded by curly braces is something like:

    {
       bool isInit;
       (void)isStillInInitMode(&amp;isInit);
       if (isInit) {
         return isInit;
       }
    }

(Don&#39;t mind the code, just stick to the curly braces... ;) )
After the curly braces there are some more bit twiddling, state checking, and basic signaling.    

I talked to the guy and his motivation was to limit the scope of variables, naming clashes, and some other that I couldn&#39;t really pick up.

From my POV this seems rather strange and I don&#39;t think that the curly braces should be in our code. I saw some good examples in all the answers on why one could surround code with curly braces, but shouldn&#39;t you separate the code into methods instead?


Unnecessary curly braces in C++?

[The HTML5 documentation recommends][1] putting the `code` element inside the `pre` element, but I don&#39;t understand how this is better or more semantic than just using the code element and CSS. In their own example:

    &lt;pre&gt;&lt;code class=&quot;language-pascal&quot;&gt;var i: Integer;
    begin
       i := 1;
    end.&lt;/code&gt;&lt;/pre&gt;

Could also be written (Making some assumptions about the browser&#39;s defaults for `pre`):

    &lt;style&gt;
    code {
        display: block;
        white-space: pre;
    }
    &lt;/style&gt;
    …
    &lt;code class=&quot;language-pascal&quot;&gt;var i: Integer;
    begin
       i := 1;
    end.&lt;/code&gt;

  [1]: http://www.w3.org/TR/2011/WD-html5-author-20110809/the-code-element.html

Even if the `pre` is there to distinguish a code *block* from an inline string of code, I don&#39;t see it being a more semantic choice than specifying the *block-ness* of the `code` in a class.

Is there a specific reason the `pre` is recommended over a CSS solution?
