FRAGMENT
========
Fragment is an HTML builder heavily based on Gestalt from the Ramaze framework.
Its main purpose is to create fragments of HTML (hence the name),
but is perfectly suited for building full pages.
In essence, Fragment works more or less like any builder.
First, how to install:
gem install fragment
Then you can require Fragment and use it that way:
require 'fragment'
default = 'HTML'
html = Fragment.create do
doctype
html(:lang=>'en') do
head { title { "My Choice" } }
body do
comment "Here starts the body"
select(:name => 'language') do
['JS', 'HTML', 'CSS'].each do |l|
option(:value => l, :selected => l==default) { l }
end
end
write "\n\n"
write "\n\n"
end
end
end
If you try this example, you might notice a couple of things:
First of all, you have a `doctype` helper which only creates an HTML5 doctype.
If you want something else, you can use the `write` method which lets you write directly in place:
write ""
The major difference with Gestalt (if you used it) is that it does not accept content
in the arguments. This simplifies the code a lot for a very small sacrifice.
So the argument is either a Hash that represents the attributes, or a string like
you would write in the HTML code.
One problem I had when creating fragments of HTML from code with a Hash for attributes
is for attributes like 'selected' or 'checked' which are a bit annoying because they do
not have a negative value (not that I know of), so you cannot write things like:
selected='not_selected'
I find this slightly irritating.
So what I did is that in the Hash, when a value is false, its key is removed.
This is what I did on the long example above for marking the default option.
Nothing fancy but quite good to be aware of.
If you do something and want to keep the scope you are in, you can use `create_here` instead of `here`. You then have access to the methods through the fragment object passed to the block:
html = Fragment.create_here do |f|
f.h1 { "" }
end
Do not hesitate to fork the project if you want to help me improve it.
Thanx
