According to http://vim.wikia.com/wiki/Search_and_replace
It appears:

    :%s/foo/\=@a/g

Also, pressing `&lt;c-r&gt;a` while in insert mode will insert the contents of register `a`.

Cool -- I never knew that.  Good question.

    :%s/foo/\=getline(10, 15)/g
    
    :%s/foo/\=join(getline(10, 15))/g

How to tell if a connection is dead in python

I&#39;d like to create a Dictionary object, with string Keys, holding values which are of a generic type. I imagine that it would look something like this:

    Dictionary&lt;string, List&lt;T&gt;&gt; d = new Dictionary&lt;string, List&lt;T&gt;&gt;();  

And enable me to add the following:

    d.Add(&quot;Numbers&quot;, new List&lt;int&gt;());
    d.Add(&quot;Letters&quot;, new List&lt;string&gt;());

I know that I can do it for a list of strings, for example, using this syntax:
    
    Dictionary&lt;string, List&lt;string&gt;&gt; d = new Dictionary&lt;string, List&lt;string&gt;&gt;();
    d.Add(&quot;Key&quot;, new List&lt;string&gt;());

but I&#39;d like to do it for a generic list if possible...

**2 questions then:**

 1. Is it possible?
 2. What&#39;s the syntax?

Can I Create a Dictionary of Generic Types?

I&#39;m using Vim, and I want to substitute some placeholder text with a long string, that spans several lines, which is already written somewhere else in the file.

Is it possible to replace a pattern with the contents of a register? Something like

    :%s/foo/&lt;contents of register A&gt;

Otherwise, is it possible to replace with a range of lines? something like

    :%s/foo/&lt;content of lines from 10 to 15&gt;




Substitute with contents of register or lines range from elsewhere in file in Vim

I'm using Vim, and I want to substitute some placeholder text with a long string, that spans several lines, which is already written somewhere else in the file.
Is it possible to replace a pattern with the contents of a register? Something like
<pre><code class="hljs language-ruby">:%s/foo/&#x3C;contents of register A>
</code></pre>
Otherwise, is it possible to replace with a range of lines? something like
<pre><code class="hljs language-ruby">:%s/foo/&#x3C;content of lines from 10 to 15>
</code></pre>

Every once in a while I want to replace all instances of values like:

    &lt;BarFoo&gt;

with

    &lt;barfoo&gt;

i.e. do a regular expression replace of all things inside angle brackets with its lowercase equivalent.

Anyone got a nice snippet of Lisp that does this? It&#39;s safe to assume that we&#39;re dealing with just ASCII values. Bonus points for anything that is generic enough to take a full regular expression, and doesn&#39;t just handle the angle brackets example. Even more bonus points to an answer which just uses `M-x query-replace-regexp`.

Thanks,

Given a (`char *`) string, I want to find all occurrences of a substring and replace them with an alternate string. I do not see any simple function that achieves this in `&lt;string.h&gt;`.

What function is to replace a substring from a string in C?

Can [this](https://stackoverflow.com/questions/367052/case-preserving-find-replace-in-visual-studio) can be done in Vim?

&gt; What I mean is: searching for &#39;BadJob&#39;
&gt; and replacing with &#39;GoodJob&#39; would do
&gt; the following replacements
&gt; 
&gt;     &#39;badjob&#39; -&gt; &#39;goodjob&#39;  
&gt;     &#39;BadJob&#39; -&gt; &#39;GoodJob&#39;  
&gt;     &#39;badJob&#39; -&gt; &#39;goodJob&#39;

How do you replace all instances of one string with another in javascript?
Example:

    someString = &#39;the cat looks like a cat&#39;
    anotherString = someString.replace(&#39;cat&#39;, &#39;dog&#39;);

results in anotherString being set to &#39;the **dog** looks like a **cat**&#39;, and I would like it to be &#39;the **dog** looks like a **dog**&#39;

Is there a way to keep the cusror location off-screen in Vim / gVim while scrolling?  Similar to many Windows editors.  
I know about marks, and do use them.  I also know the &#39;.&#39; mark (last edit location), But looking for other ideas.
I&#39;m asking this because sometimes i want to keep the cursor at some location, scroll to another place using the mouse-wheel, and then just press an arow key or something to get me back to that location.  


Vim keep cursor location while scrolling

I&#39;d like to be able to do something like this in vim (you can assume v7+ if it helps).

Type in a command like this (or something close)

    :inshtml

and have vim dump the following into the current file at the current cursor location

    &lt;!DOCTYPE html PUBLIC &quot;-//W3C//DTD XHTML 1.0 Transitional//EN&quot;
        &quot;http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd&quot;&gt;
    &lt;html xmlns=&quot;http://www.w3.org/1999/xhtml&quot;&gt;

I am trying to change the values in a text file using sed in a Bash script with the line,

    sed &#39;s/draw($prev_number;n_)/draw($number;n_)/g&#39; file.txt &gt; tmp

This will be in a `for` loop. Why is it not working?






sed substitution with Bash variables

What&#39;s the preferred way to do command substitution in bash?

I&#39;ve always done it like this:

    echo &quot;Hello, `whoami`.&quot;

But recently, I&#39;ve often seen it written like this:

    echo &quot;Hello, $(whoami).&quot;

What&#39;s the preferred syntax, and why? Or are they pretty much interchangeable?

I tend to favor the first, simply because my text editor seems to know what it is, and does syntax highlighting appropriately.

I read [here](http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_03_04.html#sect_03_04_04) that escaped characters act a bit differently in each case, but it&#39;s not clear to me which behavior is preferable, or if it just depends on the situation.

Side question: Is it bad practice to use *both* forms in one script, for example when nesting command substitutions?


Command substitution: backticks or dollar sign / paren enclosed?

I have a string with multiple commas, and the string replace method will only change the first one:

    var mystring = &quot;this,is,a,test&quot;
    mystring.replace(&quot;,&quot;,&quot;newchar&quot;, -1)

**Result**: `&quot;thisnewcharis,a,test&quot;`

The documentation indicates that the default replaces all, and that &quot;-1&quot; also indicates to replace all, but it is unsuccessful. Any thoughts?

JavaScript - Replace all commas in a string

I&#39;m trying to remove all newline characters from a string. I&#39;ve read up on how to do it, but it seems that I for some reason am unable to do so. Here is step by step what I am doing:
 
    string1 = &quot;Hello \n World&quot;
    string2 = string1.strip(&#39;\n&#39;)
    print string2

And I&#39;m still seeing the newline character in the output. I&#39;ve tried with rstrip as well, but I&#39;m still seeing the newline. Could anyone shed some light on why I&#39;m doing this wrong? Thanks.
