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
```
Or in your `Gemfile`:
```
gem '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 need more control on the scope of variables and basically stay in the
scope you are in, you can add an argument to the block which represents the
fragment itself. The change of arity changes the scope and since you are in the
current scope, every fragment method has to be called on the fragment object.
Here is an example which hopefully makes it clearer:
```
html = Fragment.create do |f|
f.h1 { "" }
end
```
Do not hesitate to fork the project if you want to help me improve it.
Thanx
