On OSX: &lt;kbd&gt;option&lt;/kbd&gt; + &lt;kbd&gt;left click&lt;/kbd&gt; at the **root node**.

On windows/linux: &lt;kbd&gt;control&lt;/kbd&gt; + &lt;kbd&gt;alt&lt;/kbd&gt; + &lt;kbd&gt;left click&lt;/kbd&gt;



For Sublime Text 3 on Linux Mint 17.2 w/ Cinnamon I had to disable the following setting:

System Settings-&gt;Windows-&gt;Behavior-&gt;Moving and Resizing Windows-&gt;Special key to move and resize windows

After that Alt+left click worked!

using purely keyboard, on a mac, to unfold

    CMD + K + 0

to fold, depending on the level of indentation

    CMD + K + {level of indentation number} (eg. CMD + K + 2)

Refer [here][1] for more details functions of sublime text. Found this really helpful

I am developing a tabbed application.

When I create a new view controller and link it to the tab bar controller, unlike the other two default view controllers, this one has no `viewcontroller.swift` file.

How can I create this file?

I am using Xcode 6 and developing the app in Swift.

I have been using the scikit-learn library. I&#39;m trying to use the Gaussian Naive Bayes Module under the scikit-learn library but I&#39;m running into the following error. TypeError: cannot perform reduce with flexible type

    training = GaussianNB()
	training = training.fit(trainData, target)
	prediction = training.predict(testData)

This is target

Is there a menu option or keyboard shortcut to collapse all expanded folders in the sidebar? It gets messy over there and seems like there should be a better way than closing them one by one.

I&#39;m working with Rails and PostgreSQL and have a basic one-to-many relationship going on, one `Auction` has many `Bid`s. However when I try and delete an auction (that has bids present) I get the following error: 

&gt; ERROR: update or delete on table &quot;auctions&quot; violates foreign key
&gt; constraint &quot;fk_rails_43e9021cbf&quot; on table &quot;bids&quot;. DETAIL: Key(id)=(1)
&gt; is still referenced from table &quot;bids&quot;.

Deleting auctions with no bids gives no error.

The part that confuses me is that inside my `Auction` model, I have:

    has_many :bids, dependent: :destroy

![Error Screen Shot (better_error gem)][1]

Since I have a dependent destroy clause, why am I still getting this error?

**EDIT:** I&#39;ve tried dropping the whole DB, then recreating/re-migrating everything - still get the same error.

For a plugin for Sublime Text I was required to install a composer package globally.

In order to do this I had to run the following command:

    composer global require &quot;asm89/twig-lint&quot; &quot;@stable&quot;

The installation started running and a few seconds later the package was installed. Voila! Well, not really.

Step two was to add some lines to my Sublime Text configuration file:

    {
        &quot;user&quot;: {
            &quot;paths&quot;: {
                &quot;windows&quot;: [&quot;C:\\Users\\yourname\\.composer\\vendor\\bin&quot;]
            },
        }
    }

However, the plugin is not working. So I decided to check the path. And it appears there is no `.composer` directory in my profile directory. It isn&#39;t in my `php` directory either. And I can&#39;t find it anywhere.

I would like to know if there&#39;s a way to locate this directory and would appreciate any suggestions that can help me get this plugin to work.

Where to find composer&#39;s global packages?

For a large project with many dependencies e.g. in the `node_modules/` folder, I noticed frequent CPU spikes because of Sublime indexing all the files in the folder.

I know I can hide files and folders using the `folder_exclude_patterns` setting, but I still want the folder to be visible in the sidebar.

How can I keep e.g. `node_modules/` in the sidebar, but exclude it from indexing?

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.

## How to (easily) get current file path in Sublime Text 3

I don&#39;t often use ST console (_I used it only once to install package manager_), but I suppose it could be good way to :
 
- get current file path like some kind **pwd** command.
- _But it doesn&#39;t work._

**Does anyone know an easy way to get current file path?**

- _to clipboard : better not a strict objective in the answer_
- _not necessary by ST command, maybe package?_

Input:

    boston beach summer figural yellow blue
    boston floral flowers still still-life food pink figural
    boston horse pink purple house flowers floral figural


Expected output:

    &quot;boston beach summer figural yellow blue&quot;
    &quot;boston floral flowers still still-life food pink figural&quot;
    &quot;boston horse pink purple house flowers floral figural&quot;

The actual input file has 600+ lines, and I&#39;m looking at a quick way to wrap each line in quotes? Does the method involve using multiple cursors? How about macros?
