xupl - ˈsəpəl
Equivalent structure to XML.
Can look like sentences or programming language text.
If you can write XML, you already know xupl.
Reduce the verbosity of XML.
Provide a more natural, readable, less verbose means of manually creating structured documents.
Similar to writing programming language text and leverage existing programming IDEs.
Facilitate creating Domain Specific Languages (DSLs).
Here is a xupl document
note:
to: "Tove"
from: "Jani"
heading: "Reminder"
body: "Don't forget me this weekend!"
For this XML
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>
Not only is the xupl less verbose, it's far easier to read. This becomes much more evident when namespaces are used.
note: to: "Tove". from: "Jani". heading: "Reminder". body: "Don't forget me this weekend!".
note {
to {"Tove"}
from {"Jani"}
heading: "Reminder"
body: "Don't forget me this weekend!"
}
This enables tools capable of matching braces.
Attributes are specified as name "value" or "value" name.
e.g.
a "/nicerobot/xupl/wiki/xupl" href:"xupl"
and
a href "/nicerobot/xupl/wiki/xupl":"xupl"
and
a href "/nicerobot/xupl/wiki/xupl"{"xupl"}
all produce:
<a href="/nicerobot/xupl/wiki/xupl">xupl</a>
Numeric values, including floats, can omit surrounding quotes.
e.g.
size 100 width, 100 height
produces:
<size width="100" height="100" />
Attribute values can remain unquoted for native types:
numbers: decimal int, float, base 2,8,10,16,32, and 64 constants- sizes: n
pxnemn% URLsmailto:#tags|rgb@names~durations^date!priority
html:
head{title:"My xupl"}
body:
a "/nicerobot/xupl/wiki/xupl":"xupl"
This example demonstrates a couple points.
- When using
tag:syntax, EOF will close all open tags. - Certain tags have default attribute names. e.g.
atag's default attribute name ishref.
<html>
<head><title>My xupl</title></head>
<body>
<a href="/nicerobot/xupl/wiki/xupl">xupl</a>
</body>
</html>
