README
lucid
Clear to write, read and edit DSL for writing HTML
lucid-from-html will convert html to the lucid
DSL, though it is experimental.
Introduction
HTML terms in Lucid are written with a postfix ‘_
’ to indicate data
rather than code. Some examples:
p_
, class_
, table_
, style_
See Lucid.Html5
for a complete list of Html5 combinators.
Plain text is written using the OverloadedStrings
and
ExtendedDefaultRules
extensions, and is automatically escaped:
λ> "123 < 456" :: Html ()
123 < 456
Elements nest by function application:
λ> table_ (tr_ (td_ (p_ "Hello, World!"))) :: Html ()
<table><tr><td><p>Hello, World!</p></td></tr></table>
Elements are juxtaposed via monoidal append:
λ> p_ "hello" <> p_ "sup" :: Html ()
<p>hello</p><p>sup</p>
Or monadic sequencing:
λ> div_ (do p_ "hello"; p_ "sup") :: Html ()
<div><p>hello</p><p>sup</p></div>
Attributes are set by providing an argument list:
λ> p_ [class_ "brand"] "Lucid Inc" :: Html ()
<p class="brand">Lucid Inc</p>
Here is a fuller example of Lucid:
table_ [rows_ "2"]
(tr_ (do td_ [class_ "top",colspan_ "2",style_ "color:red"]
(p_ "Hello, attributes!")
td_ "yay!"))
<table rows="2">
<tr>
<td style="color:red" colspan="2" class="top">
<p>Hello, attributes!</p>
</td>
<td>yay!</td>
</tr>
</table>
Rendering
For proper rendering you can easily run some HTML immediately with:
λ> renderText (p_ "Hello!")
"<p>Hello!</p>"
Or to bytes:
λ> renderBS (p_ [style_ "color:red"] "Hello!")
"<p style=\"color:red\">Hello!</p>"
For ease of use in GHCi, there is a Show
instance, as
demonstrated above.
If the above rendering functions aren't suited for your purpose, you
can run the monad directly via execHtml
and use the more low-level
blaze Builder
, which has a plethora of output modes in
Blaze.ByteString.Builder.
See the documentation for the Lucid
module for information about
using it as a monad transformer.
Transforming
You can use lift
to call parent monads.
λ> runReader (renderTextT (html_ (body_ (do name <- lift ask
p_ [class_ "name"] (toHtml name)))))
("Chris" :: String)
"<html><body><p class=\"name\">Chris</p></body></html>"
