Of course, when your done generating new code, you will need to enable it again or comfy won't work right.

Save replace value in vim
let @y = '' let @z = '/<pre [^>]\+\+><return>' let @z .= 'v/><return>' let @z .= '"yy' normal @zhttp://superuser.com/questions/575831/save-replace-value-in-vim
Clear out @y register. Search for desired string, start selecting until specified pattern, and while selection is active, shove it in the @y register ("Yy would append to the @y register).
Formatting columns in a selected block
:%!column -t "in visual mode :!column -t " establish columns by splitting on Tab character " Ctrl-V, Tab to generate '^I' :%!column -t -s "^I"http://stackoverflow.com/questions/1229900/reformat-in-vim-for-a-nice-column-layout
Because my files didn't have a space I had to use :%!column -t -s ','. It removes the commas, so they're not technicaly csv files anymore. But arranges them beautifully, which is what I needed.
http://stackoverflow.com/questions/1229900/reformat-in-vim-for-a-nice-column-layout
To format only the content of the visual block, delimit on
:!column -t -s '<tab>'
Works like a champ.

Substitute with contents of register or lines range from elsewhere in file in Vim
:%s/foo/\=@a/ghttp://stackoverflow.com/questions/662734/substitute-with-contents-of-register-or-lines-range-from-elsewhere-in-file-in-vi
No other replacement values can be included with '\=@a'. Otherwise, it won't work.

Wow! This stuff is cryptic.
What is 'f' and 'F' and how do they work?
F)vi(http://learnvimscriptthehardway.stevelosh.com/chapters/15.html
:normal! is something we'll talk about in a later chapter, but for now it's enough to know that it is a command used to simulate pressing keys in normal mode. For example, running :normal! dddd will delete two lines, just like pressing dddd. The

(f)ind character; (f)next, (F)previous
(vi)select block body delimited by '()', '{}', '<>', or '[]'
Escaping single quotes is easy, but a little verbose
"'" . x . "'"http://vim.1045645.n5.nabble.com/escape-and-td1200763.html
Remember, the spaces between concatenated strings is important!
Search only over a visual range
/\%Vpattern <div>hello</div>http://vim.wikia.com/wiki/Search_only_over_a_visual_range
This saved my skin; the trick is to create a highlighted range, escape, and then use the substitution flag '\%V' to limit substitution to the last selected block. When including a '^' before the flag, it means the first in the selection, not each line in the selection. Interesting...
Getting zen-code to format snippet using multi-line
let @z = 'gvj<escape>A<return><return><escape>gv<c-y>,div.notes>p*<return>'
A little difficult to see from code snippet, but add a line to the currently selected block, add a couple of new lines after the block, select the last selected block again and then execute the zen-code command.

I'm beginning to concede that Mockito is the option most similar to Ruby style mocking.

}
}
http://stackoverflow.com/questions/13364406/mockito-mock-a-constructor-with-parameter
Mocking constructors requires something extra from just Mockito.
Mocking Static Method
@PrepareForTest(Static.class); // Static.class contains static methods
PowerMockito.mockStatic(Static.class);
Mockito.when(Static.firstStaticMethod(param)).thenReturn(value);

how do I mock Class myVar in Mockito (or PowerMock if needed)?

return instance;

http://stackoverflow.com/questions/13057933/how-do-i-mock-class-extends-list-myvar-in-mockito-or-powermock-if-needed
Mockito is designed exclusively for mocking instances of objects. Under the hood, the mock method actually creates a proxy that receives calls to all non-final methods, and logs and stubs those calls as needed. There's no good way to use Mockito to replace a function on the Class object itself.

Mockito documentation (1.6)
//Let's import Mockito statically so that the code looks clearer
import static org.mockito.Mockito.*;
//mock creation
List mockedList = mock(List.class);
//using mock object
mockedList.add("one");
mockedList.clear();
//verification
verify(mockedList).add("one");
verify(mockedList).clear();

It appears this has a little guide of common uses for Mockito.
Mockito matchers
//stubbing using anyInt() argument matcher
when(mockedList.get(anyInt())).thenReturn("element");
//following prints "element"
System.out.println(mockedList.get(999));
//you can also verify using argument matcher
verify(mockedList).get(anyInt());

Working with J2EE applications is something like wandering in a jungle: you never quite know what wild animal you’ll find around the next corner... whatever it is, you’re guaranteed to spend countless hours wasting time learning things you really didn’t want to know.
[Let me] show how you can get your J2EE application under control by using JRuby and RSpec.

Testing is one of the easy ways to sneak JRuby into your organization because it is easier to write tests in dynamic languages (especially mock object tests) and it isn't code that is deployed, so it eases the minds of the furniture police somewhat.

}

http://evan.tiggerpalace.com/articles/2008/05/02/mocking-core-java-classes-with-jmockit/
So, yes, Virginia, it is possible to mock core classes... To make this work practically would likely necessitate launching a separate VM so as to 'scope' the mock to a particular test.
Fugly.
