I am trying to run rspec for Ruby on Rails.  I am running Rails 4.1.1.  I have installed the gem, have established a spec folder with some tests.  I have created a directory through `$ rails g rspec:install`  

I tried to create a testing database through `$ rake db:test:prepare` but it throws this error message:

    WARNING: db:test:prepare is deprecated. The Rails test helper now maintains your test 
    schema automatically, see the release notes for details.

So I ended up looking at [this stack overflow post](https://stackoverflow.com/questions/23351783/when-i-ran-bundle-exec-rake-testprepare-it-errored-out-but-bundle-exec-rake), and of the two options, the one that worked was:

    rake db:schema:load RAILS_ENV=test 

So, **now I need to run rspec**. 

When I run `$ rspec spec` from the command line I get this error:

    /Users/myname/.rbenv/versions/2.1.1/lib/ruby/2.1.0/rubygems/core_ext/
    kernel_require.rb:55:in `require&#39;: cannot load such file -- rails_helper (LoadError)

How do I resolve this so that I can start running tests?

Im trying to compile some code in I&#39;m using Intellij Ultimate 13.1.4, but I get the following error and I have no idea what it means:

    Information:Using javac 1.7.0_55 to compile java sources
    Information:java: Errors occurred while compiling module &#39;Example&#39;
    Information:Compilation completed with 1 error and 0 warnings in 3 sec
    Information:1 error
    Information:0 warnings
    Error:java: invalid source release: 8

My guess is that its something related to Java 8 vs Java 7, but I have no idea what specifically. I&#39;ve tried to Google around for this message, but they either talk about `javac` or `target release`, so it doesn&#39;t exactly seem to apply.

I&#39;m new to both Maven and IntelliJ IDEA.

I have a Maven project written in Java 8. Whenever I try to build it (Maven Projects window -&gt; Lifecycle -&gt; compile -&gt; Run Maven Build) I get a series of compilation errors:

    [ERROR] path/to/file.java:[26,52] lambda expressions are not supported in -source 1.5
    (use -source 8 or higher to enable lambda expressions)

Where am I supposed to change the value of the -source parameter? I tried adding it as an additional parameter in Settings -&gt; Compiler - &gt; Java Compiler, but I got the same results.

The project&#39;s and module&#39;s language levels are both set to 8.0.

I&#39;m using Maven 3.2.3 and IntelliJ IDEA Community Edition 13.1.2.

I have changed my Android Studio theme from Default to Darcula.

But when I want to search anything then I need to go to browser which is very bright. 

Now I want to revert the theme from Darcula to default theme in Android Studio. When I do that, it just changes background color and font color of Editor window. I want to change the whole window to be default instead of black.

I have to develop a plugin for Eclipse but I prefer IntelliJ IDEA as IDE. Is it possible to configure IDEA for Eclipse plugin development?

How to use IntelliJ IDEA for Eclipse plugin development?

When a case class has many fields and their names are long, it is often a good idea to write each field in each line like:

    case class Person (
      name: String,
      age: Int
    )


This resembles C/C++ `struct` definition and totally readable even when the case class becomes bigger. But IntelliJ IDEA&#39;s default Scala plugin automatically changes its indentation:

    case class Person (
                        name: String,
                        age: Int
                        )

which looks weird to me, but the [Scala Style Guide](http://docs.scala-lang.org/style/indentation.html) doesn&#39;t mention anything about case class indentation.

I couldn&#39;t find anything in the IDE settings that can change this behaviour. Is there an option to make the auto-indentation work like the way I described above or disable auto-indentation for case classes?


IntelliJ Scala Plugin&#39;s case class indentation is absurd

Is there a way to begin a block of code with a with statement, but conditionally?

Something like:

    if needs_with():
        with get_stuff() as gs:
        
    # do nearly the same large block of stuff,
    # involving gs or not, depending on needs_with()

To clarify, one scenario would have a block encased in the with statement, while another possibility would be the same block, but not encased (i.e., as if it wasn&#39;t indented)

Initial experiments of course give indentation errors..

How to reindent `Json` code with a **shortcut**?

I&#39;ve already installed `packageControl` and it works.

I already tried `JsonReindent` package but it has not a shortcut by default and i don&#39;t know its command name.

I already have this command (from my previous sublimetext2 on another pc, where it works fine):

    // JSON reindent
	{ &quot;keys&quot;: [&quot;ctrl+shift+j&quot;, &quot;ctrl+shift+j&quot;], &quot;command&quot;: &quot;json_reindent&quot; },

But here it doesn&#39;t work.

Can the code read itself in this way?

All I want is the output from the more nested parts of the code to be more nested. In the same way that this makes code easier to read, it would make the output easier to read. 

Of course I could implement this manually, using e.g. `.format()`, but what I had in mind was a custom print function which would `print(i*&#39; &#39; + string)` where `i` is the indentation level. This would be a quick way to make readable output on my terminal. 

Is there a better way to do this which avoids painstaking manual formatting?

I want to indent a specific section of code in Visual Studio Code.

I read *[How do you format code in Visual Studio Code?][1]* that gives shortcuts to indent the whole code, but it doesn&#39;t work when selecting a specific section of code.

I tried &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;F&lt;/kbd&gt; after selecting some line in my code, but the whole file is indented. I&#39;m on Windows with Visual Studio Code Insider 1.8.0. How can I do it?

How to use code formatter in Xcode for Swift?

I have looked at various documentation and similar questions on here, but cannot seem to find the particular solution. Apologies if I have missed anything obvious or have repeated this question!

As a bit of background info, I have implemented 4 graphs using the Chart.js plugin and passed in the required data using PHP from a database. This is all working correctly and is fine. 

My problem is I need to display the data in the tooltips as formatted data aka. as numeric with %. As an example, one of my data from database is -0.17222. I have formatted it as a percentage to display in my table and all is well. However, when setting the data for the chart.js bar graph, the data is obviously missing this formatting and displaying as the -0.17222 which I do not want.

Sorry, I wanted to post a picture, but my reputation is too rubbish!

I grab data from database, then set into my table:

    var kpiRex = new Handsontable(example1, {
        data: getRexData(),

 Then I feed this data like so in the chart section:

    data: kpiRex.getDataAtRow(3)

Any help would be great! I&#39;ve been stuck on this for hours and it&#39;s probably something really simple I am overlooking.

What is the equivalent of &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;K&lt;/kbd&gt; + &lt;kbd&gt;F&lt;/kbd&gt; and &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;K&lt;/kbd&gt; + &lt;kbd&gt;D&lt;/kbd&gt; on Windows in Visual Studio for formatting, or &quot;beautifying&quot; code in the Visual Studio Code editor?

How do you format code in Visual Studio Code (VSCode)?

Let&#39;s say I type in the following code and format it.

    if (condition) { /* Hello! */ }

If this is C# code, it is formatted like this:

    if (condition)
    {
        // Hello!
    }

If it is JavaScript, VSCode formats it like this:

    if (condition) {
        // Hello!
    }
So how can I use the first formatting style (curly braces on new lines) for all languages? I can&#39;t find a setting or something similar. Suggestions?

How do I set up VSCode to put curly braces on a new line?

I&#39;m looking for a `clang-format` setting to prevent the tool from removing line breaks.

For example, I have my `ColumnLimit` set to 120, and here&#39;s what happens when I reformat some sample code.

Before:

    #include &lt;vector&gt;
    #include &lt;string&gt;
    
    std::vector&lt;std::string&gt; get_vec()
    {
       return std::vector&lt;std::string&gt; {
          &quot;this is a test&quot;,
          &quot;some of the lines are longer&quot;,
          &quot;than other, but I would like&quot;,
          &quot;to keep them on separate lines&quot;
       };
    }
    
    int main()
    {
       auto vec = get_vec();
    }

After:

    #include &lt;vector&gt;
    #include &lt;string&gt;
    
    std::vector&lt;std::string&gt; get_vec()
    {
       return std::vector&lt;std::string&gt;{&quot;this is a test&quot;, &quot;some of the lines are longer&quot;, &quot;than other, but I would like&quot;,
             &quot;to keep them on separate lines&quot;};
    }
    
    int main()
    {
       auto vec = get_vec();
    }


What I would like is that the tool breaks lines that are over 120 characters, but doesn&#39;t decide to combine lines just because they are less than 120 characters.

Is there such an option?  Nothing in the docs stood out to me.
