Try the following instead:

    let mapleader=&quot; &quot;

And remember to write the following line before that, to make sure spacebar doesn&#39;t have any mapping beforehand:

    nnoremap &lt;SPACE&gt; &lt;Nop&gt;

Mapleader is a Vim string variable. To use space as leader, you must escape the special character.

    let mapleader=&quot;\&lt;Space&gt;&quot;


For more info see,

http://vimdoc.sourceforge.net/htmldoc/eval.html#expr-quote

**EDIT:**

This no longer works for me in my version of Vim. Even with the suggestion in the comments of unmapping the spacebar in normal mode by running `nnoremap &lt;SPACE&gt; &lt;Nop&gt;`.

I ending up going with the solution given in the answer below.

```
map &lt;Space&gt; &lt;Leader&gt;
```




The above solutions are great, however, nothing shows up in the bottom right command corner. If you don&#39;t have any use for the `\` key anyway, try using
`map &lt;SPACE&gt; &lt;leader&gt;` and `\` will show up in the command corner. That and you don&#39;t have to unmap space first, as suggested in the commends above.

nnoremap &lt;space&lt;f&gt;&gt; &lt;Nop&lt;f&gt;&gt;  
nnoremap &lt;nowait&lt;f&gt;&gt; &lt;space&lt;f&gt;&gt; /

How do I specify Vim settings for all files under the current directory?

The ideal solution would be if Vim searched for and read a .vimrc in the current directory before searching for ~/.vimrc, and apply the settings there for the entire tree.

I&#39;ve seen a [plugin](http://www.vim.org/scripts/script.php?script_id=1860), but this means the applied settings aren&#39;t transparent since they require the plugin to be installed.  In contrast, a modeline is transparent since regardless of a user&#39;s vimrc or specific vim invocation the modeline settings will be applied for that file.

Things I tried are

 * placing a .vimrc in the working directory
 * `:so vimrc` in the modeline.

I suppose both don&#39;t work for security reasons.  I don&#39;t need the full power of a vimrc; being bound to settings acceptable by a modeline would suffice.  My goal is to make it easier for vimmers to adopt coding standards in a project.

I&#39;ve been using Vim for a while, and I can&#39;t get proper HTML indentation working in PHP files.

For example, what I want is for each child to be indented one tab more than it&#39;s parent, as shown below.

	&lt;?php
	if(isset($sports)) {
		//Do something
	?&gt;
	&lt;div&gt;
		&lt;label&gt;Uniform Size&lt;/label&gt;
		&lt;ul&gt;
			&lt;li class=&quot;left&quot;&gt;&lt;label for=&quot;s&quot; class=&quot;small&quot;&gt;S&lt;/label&gt;&lt;input type=&quot;radio&quot; name=&quot;size[]&quot; value=&quot;S&quot; id=&quot;s&quot; class=&quot;radio&quot; /&gt;&lt;/li&gt;
			&lt;li class=&quot;left&quot;&gt;&lt;label for=&quot;m&quot; class=&quot;small&quot;&gt;M&lt;/label&gt;&lt;input type=&quot;radio&quot; name=&quot;size[]&quot; value=&quot;M&quot; id=&quot;m&quot; class=&quot;radio&quot; /&gt;&lt;/li&gt;
			&lt;li class=&quot;left&quot;&gt;&lt;label for=&quot;l&quot; class=&quot;small&quot;&gt;L&lt;/label&gt;&lt;input type=&quot;radio&quot; name=&quot;size[]&quot; value=&quot;L&quot; id=&quot;l&quot; class=&quot;radio&quot; /&gt;&lt;/li&gt;
			&lt;li class=&quot;left&quot;&gt;&lt;label for=&quot;xl&quot; class=&quot;small&quot;&gt;XL&lt;/label&gt;&lt;input type=&quot;radio&quot; name=&quot;size[]&quot; value=&quot;XL&quot; id=&quot;xl&quot; class=&quot;radio&quot; /&gt;&lt;/li&gt;
		&lt;/ul&gt;
	&lt;/div&gt;
	&lt;?php
	}
	?&gt;


Using the [PHP-correct-Indent][1] script, the code results in being formatted as follows:
	

    &lt;?php
    if(isset($sports)) {
    	//Do something
    ?&gt;
    &lt;div&gt;
    &lt;label&gt;Uniform Size&lt;/label&gt;
    &lt;ul&gt;
    &lt;li class=&quot;left&quot;&gt;&lt;label for=&quot;s&quot; class=&quot;small&quot;&gt;S&lt;/label&gt;&lt;input type=&quot;radio&quot; name=&quot;size[]&quot; value=&quot;S&quot; id=&quot;s&quot; class=&quot;radio&quot; /&gt;&lt;/li&gt;
    &lt;li class=&quot;left&quot;&gt;&lt;label for=&quot;m&quot; class=&quot;small&quot;&gt;M&lt;/label&gt;&lt;input type=&quot;radio&quot; name=&quot;size[]&quot; value=&quot;M&quot; id=&quot;m&quot; class=&quot;radio&quot; /&gt;&lt;/li&gt;
    &lt;li class=&quot;left&quot;&gt;&lt;label for=&quot;l&quot; class=&quot;small&quot;&gt;L&lt;/label&gt;&lt;input type=&quot;radio&quot; name=&quot;size[]&quot; value=&quot;L&quot; id=&quot;l&quot; class=&quot;radio&quot; /&gt;&lt;/li&gt;
    &lt;li class=&quot;left&quot;&gt;&lt;label for=&quot;xl&quot; class=&quot;small&quot;&gt;XL&lt;/label&gt;&lt;input type=&quot;radio&quot; name=&quot;size[]&quot; value=&quot;XL&quot; id=&quot;xl&quot; class=&quot;radio&quot; /&gt;&lt;/li&gt;
    &lt;/ul&gt;
    &lt;/div&gt;
    &lt;?php
    }
    ?&gt;

Even with indented HTML which I then add PHP code to, the indentation is ignored, moving new lines of HTML code without any indentation at all.

So, is there any way that I can get the indentation format that I want working with HTML within PHP files, using Vim?

I spend my days in vim, currently writing a lot of JavaScript. I&#39;ve been trying to find a way to integrate JSLint or something similar into vim to improve my coding. Has anyone managed to do something like this?

Is there an easy way in C# to read a properties file that has each property on a separate line followed by an equals sign and the value, such as the following:
 
    ServerName=prod-srv1
    Port=8888
    CustomProperty=Any value

In Java, the Properties class handles this parsing easily:

    Properties myProperties=new Properties();
    FileInputStream fis = new FileInputStream (new File(&quot;CustomProps.properties&quot;));
    myProperties.load(fis);
    System.out.println(myProperties.getProperty(&quot;ServerName&quot;));
    System.out.println(myProperties.getProperty(&quot;CustomProperty&quot;));

I can easily load the file in C# and parse each line, but is there a built in way to easily get a property without having to parse out the key name and equals sign myself?  The C# information I have found seems to always favor XML, but this is an existing file that I don&#39;t control and I would prefer to keep it in the existing format as it will require more time to get another team to change it to XML than parsing the existing file.

When I change the connection string using this code, it does not reload `app.config` at runtime. I expected it to reload similarly to how we reload `app.config`.

I am running Django, FastCGI, and Nginx.  I am creating an api of sorts that where someone can send some data via XML which I will process and then return some status codes for each node that was sent over.

The problem is that Nginx will throw a 504 Gateway Time-out if I take too long to process the XML -- I think longer than 60 seconds.

So I would like to set up Nginx so that if any requests matching the location /api will not time out for 120 seconds.  What setting will accomplish that.

What I have so far is:

        # Handles all api calls
        location ^~ /api/ {
            proxy_read_timeout 120;
            proxy_connect_timeout 120;
            fastcgi_pass 127.0.0.1:8080;
        }

Edit: What I have is not working :)

How do I prevent a Gateway Timeout with FastCGI on Nginx

I have two applications one a console application and the other an ASP.NET app. They both need to know the same appSettings and connectionStrings. So ideally I would like to use the configSource property of app.config/web.config files to point that to a central location. For example  

    &lt;connectionStrings configSource=&quot;D:\connectionStrings.config&quot;/&gt;
	&lt;appSettings configSource=&quot;D:\appSettings.config&quot;/&gt;

That however fails with an error:  

&gt; The configSource attribute is invalid.: The configSource &#39;D:\\appSettings.config&#39; is invalid. It must refer to a file in the same directory or in a subdirectory as the configuration file.

Is there anyway to still use the configuration managers appSettings/connectionStrings and get the values from an external location?  
I&#39;m happy with having to add code to do it, but I don&#39;t want to have to replace the entire configuration manager system.

Given a dictionary like so:

    my_map = {&#39;a&#39;: 1, &#39;b&#39;: 2}

How can one invert this map to get:

    inv_map = {1: &#39;a&#39;, 2: &#39;b&#39;}


Reverse / invert a dictionary mapping

I have a data structure which essentially amounts to a nested dictionary. Let&#39;s say it looks like this:

    
    {&#39;new jersey&#39;: {&#39;mercer county&#39;: {&#39;plumbers&#39;: 3,
                                      &#39;programmers&#39;: 81},
                    &#39;middlesex county&#39;: {&#39;programmers&#39;: 81,
                                         &#39;salesmen&#39;: 62}},
     &#39;new york&#39;: {&#39;queens county&#39;: {&#39;plumbers&#39;: 9,
                                    &#39;salesmen&#39;: 36}}}


Now, maintaining and creating this is pretty painful; every time I have a new state/county/profession I have to create the lower layer dictionaries via obnoxious try/catch blocks. Moreover, I have to create annoying nested iterators if I want to go over all the values. 

I could also use tuples as keys, like such:

    {(&#39;new jersey&#39;, &#39;mercer county&#39;, &#39;plumbers&#39;): 3,
     (&#39;new jersey&#39;, &#39;mercer county&#39;, &#39;programmers&#39;): 81,
     (&#39;new jersey&#39;, &#39;middlesex county&#39;, &#39;programmers&#39;): 81,
     (&#39;new jersey&#39;, &#39;middlesex county&#39;, &#39;salesmen&#39;): 62,
     (&#39;new york&#39;, &#39;queens county&#39;, &#39;plumbers&#39;): 9,
     (&#39;new york&#39;, &#39;queens county&#39;, &#39;salesmen&#39;): 36}

This makes iterating over the values very simple and natural, but it is more syntactically painful to do things like aggregations and looking at subsets of the dictionary (e.g. if I just want to go state-by-state).

Basically, sometimes I want to think of a nested dictionary as a flat dictionary, and sometimes I want to think of it indeed as a complex hierarchy. I could wrap this all in a class, but it seems like someone might have done this already. Alternatively, it seems like there might be some really elegant syntactical constructions to do this. 

How could I do this better?

Addendum: I&#39;m aware of `setdefault()` but it doesn&#39;t really make for clean syntax.  Also, each sub-dictionary you create still needs to have `setdefault()` manually set.

What is the best way to implement nested dictionaries?

Imagine two positive integers A and B. I want to combine these two into a single integer C. 

There can be no other integers D and E which combine to C.
So combining them with the addition operator doesn&#39;t work. Eg 30 + 10 = 40 = 40 + 0 = 39 + 1
Neither does concatination work. Eg &quot;31&quot; + &quot;2&quot; = 312 = &quot;3&quot; + &quot;12&quot;

This combination operation should also be deterministic (always yield the same result with the same inputs) _and_ should always yield an integer on either the positive or the negative side of integers.

Mapping two integers to one, in a unique and deterministic way

I receive a dictionary as input, and would like to to return a dictionary whose keys will be the input&#39;s values and whose value will be the corresponding input keys. Values are unique.

For example, say my input is:

    a = dict()
    a[&#39;one&#39;]=1
    a[&#39;two&#39;]=2

I would like my output to be:

    {1: &#39;one&#39;, 2: &#39;two&#39;}

To clarify I would like my result to be the equivalent of the following:

    res = dict()
    res[1] = &#39;one&#39;
    res[2] = &#39;two&#39;

Any neat Pythonic way to achieve this?

I have an `NSTableView` with several text columns. By default, the `dataCell` for these columns is an instance of Apple&#39;s `NSTextFieldCell` class, which does all kinds of wonderful things, but it draws text aligned with the top of the cell, and I want the text to be vertically centered in the cell.

There is an internal flag in `NSTextFieldCell` that can be used to vertically center the text, and it works beautifully. However, since it is an internal flag, its use is not sanctioned by Apple and it could simply disappear without warning in a future release. I am currently using this internal flag because it is simple and effective. Apple has obviously spent some time implementing the feature, so I dislike the idea of re-implementing it.

So; my question is this: **What is the right way to implement something that behaves exactly like Apple&#39;s NStextFieldCell, but draws vertically centered text instead of top-aligned?**

For the record, here is my current &quot;solution&quot;:

    @interface NSTextFieldCell (MyCategories)
    - (void)setVerticalCentering:(BOOL)centerVertical;
    @end
    
    @implementation NSTextFieldCell (MyCategories)
    - (void)setVerticalCentering:(BOOL)centerVertical
    {
    	@try { _cFlags.vCentered = centerVertical ? 1 : 0; }
    	@catch(...) { NSLog(@&quot;*** unable to set vertical centering&quot;); }
    }
    @end

Used as follows:

    [[myTableColumn dataCell] setVerticalCentering:YES];

Is there a &quot;right&quot; way to have NSTextFieldCell draw vertically centered text?

I want to create a customized ListView (or similar) which will behave like a closed (circular) one:

   1. scrolling down - after the last item was reached the first begins  (.., n-1, n, 1, 2, ..)
   2. scrolling upward - after the first item was reached the last begins (.., 2, 1, n, n-1, ..)

It sounds simple conceptually but, apparently, there is no straightforward approach to do this.
Can anyone point me to the right solution ?
Thank you !

I have already received an answer (from Streets Of Boston on Android-Developers google groups), but it sounds somehow ugly :) - 

&gt; I did this by creating my own
&gt; list-adapter (subclassed from
&gt; BaseAdapter).
&gt; 
&gt; I coded my own list-adapter in such a
&gt; way that its getCount() method returns
&gt; a HUUUUGE number.
&gt; 
&gt; And if item &#39;x&#39; is selected, then this
&gt; item corresponds to adapter
&gt; position=&#39;adapter.getCount()/2+x&#39;
&gt; 
&gt; And for my adapter&#39;s method
&gt; getItem(int position), i look in my
&gt; array that backs up the adapter and
&gt; fetch the item on index:
&gt;     (position-getCount()/2) % myDataItems.length
&gt; 
&gt; You need to do some more &#39;special&#39;
&gt; stuff to make it all work correctly,
&gt; but you get the idea.
&gt; 
&gt; In principle, it is still possible to
&gt; reach the end or the beginning of the
&gt; list, but if you set getCount() to
&gt; around a million or so, this is hard
&gt; to do :-)

How to create a closed (circular) ListView?

I did some digging in Android code, and saw the use of &lt;animated-rotate&gt; in the indeterminate progress bar. after trying to create my own drawable with this tag:

    &lt;animated-rotate xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:drawable=&quot;@drawable/spinner_pia&quot;
        android:pivotX=&quot;50%&quot;
        android:pivotY=&quot;50%&quot;
        android:framesCount=&quot;12&quot;
        android:frameDuration=&quot;100&quot; /&gt;

I get an error:
&quot;No resource identifier found for attribute &#39;frameDuration&#39; in package &#39;android&#39;&quot; - which means that frameDuration is a private attribute. 
Is there a way to use this &quot;animate-rotate&quot; feature?

My task is to replace the system&#39;s default indeterminate progress bar. I&#39;d like to do it with as little code as possible (just change few attributes if possible).
Using the ProgressBar view, setting:

    android:indeterminateOnly=&quot;true&quot;
    android:indeterminateBehavior=&quot;cycle&quot;
    android:indeterminateDuration=&quot;3500&quot;
    android:indeterminateDrawable=&quot;@drawable/pia_sivuvator&quot;

and point &quot;@drawable/pia_sivuvator&quot; to that &lt;animate-rotate&gt; object would&#39;ve make my task as elegant as they come but I&#39;m stuck on those private attributes.

help?


Android Animate Rotate

Like many people these days I have been trying the different features that C++11 brings. One of my favorites is the &quot;range-based for loops&quot;.

I understand that:

    for(Type&amp; v : a) { ... }

Is equivalent to:

    for(auto iv = begin(a); iv != end(a); ++iv)
    {
      Type&amp; v = *iv;
      ...
    }

And that `begin()` simply returns `a.begin()` for standard containers.

But what if I want to *make my custom type &quot;range-based for loop&quot;-aware*?

Should I just specialize `begin()` and `end()`?

If my custom type belongs to the namespace `xml`, should I define `xml::begin()` or `std::begin()` ?

In short, what are the guidelines to do that?
