By default vim opens .ss files with some other file format syntax highlighting.

To enable HTML (actually XHTML) syntax highlighting on your .SS Silverstripe template files, create (or edit) your ~/.vim/filetype.vim file. Then enter this:

au BufNewFile,BufRead *.ss      setf xhtml

Then open a .ss file and it’ll give you nice HTML syntax highlighting. And because it’s in your home directory, it’ll keep working even after you upgrade vim.

When upgrading a website you might see source code like this:

<span style="font-family: Arial; color: #0000ff; font-size: small;">Some text goes here</span>

You’re using CSS now and all those <span> tags are ruining it. In gvim, do this search and substitute:

%s/<span.\{-}>//g

Then to get rid of the </span> tags, do this:

:%s/<\/span>//g

If there are ^M at the end of every line when you view them in vim, you can do this:
:%s/^M//g
To get the “^M” bit, hit ctrl-v and then ctrl-m.

To reverse the order of lines, eg 1-5
: 1,5 g/^/m0
For example,

one
two
three
four
five

becomes

five
four
three
two
one

To remove blank lines
: %g/^$/d

Delete all lines that don’t contain “string”
: %v/string/d

Replace all in the current file instances of:

<a href=”link_to_somewhere.html”>link</a>

with:

<a href=”#”>link</a>

:%s/\(a href="\)\(\S\+\)\("\)/\1#\3/g

This is great if you’ve got a big HTML file that you want to demo to a client where you don’t want the links to do anything when clicked.

You could also use javascript to do the same thing – just “return false” for all <a> elements on the page.

You’ve got a web form with lots of fields, and you want to POST them to a PHP script. Open vim, and list the INPUT tag’s NAME attributes, one per line.

<?php
firstname
lastname
address1
address2
state
postcode
?>

Now with some search-and-replace magic we can save ourself a lot of boring typing. Hit ‘escape’ to get out of insert mode, type a colon (”:”) and copy-paste this:

%s/^\(\S\+\)/\$\1 = \$_POST\[\'\1\'\];

I won’t bother explaining it unless someone asks. But what you should end up with is this:

<?php
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$address1 = $_POST['address1'];
$address2 = $_POST['address2'];
$state = $_POST['state'];
$postcode = $_POST['postcode'];
?>

Perhaps not worth it when you have 6 variables like this example; but quite handy when you have 60 variables!
