vim mappings – easy way to do things.

You can use vim mappings to make some of your editor tasks very simple. Here I am giving you just a example, but you could always let your imagination run wild.

:nmap ,b Oj0c$**hP

And what do we do here.

O – Add a new line

– Go to normal mode

j – go to newly added line

0 – Go to begining of line

c$ – Change till end of line

vim maps – simple commands to do stuff.

Some time back, I was working on some script for logging and I wanted to change the class to function like this:

$logger->Debug("Test string");
loggerFunc("Debug", "Test String");

As you can see, this change could be quite frustrating if you have quite a few references. And thus vim comes to rescue.

Simple map like ::

:map ,mm :s/(.*)$logger->(.*)((.*)).*/1loggerFunc("2",3);/

and then I can do “/$logger->” and then “n” to go to next match. Just do “,mm” and the line is re-factored.

when you press f9 'paste' is on , press f9 again and 'paste' is off, and so forth (works in insert-mode and command-mode)

<a class="zem_slink" title="Vim (text editor)" rel="homepage" href="http://www.vim.org/">vim&#8217;s pastetoggle: when you press f9 &#8217;paste&#8217; is on , press f9 again and &#8217;paste&#8217; is off, and so forth (works in <a class="zem_slink" title="Insert key" rel="wikipedia" href="http://en.wikipedia.org/wiki/Insert_key">insert-mode and command-mode) $ nmap :set paste!:set paste? Sets as paste toggle, with visual confirmation of state

vim understanding the various modes and using the yanking more efficiently.

We will look at the vim modes today. Sometime back , I was looking at copying a function body. So I was basically looking to copy the lines till matching &#8221;}&#8221;. I found a plugin called <a href="http://www.vim.org/scripts/script.php?script_id=1234" target="_blank">yankring which would allow me to yank the text in various combinations. So I can copy a function by going to the begining of the function and then &#8221;y}&#8221;. That is very simple to understand right? Wrong!!!
