SharpTemplar
SharpTemplar is a library for writing SGML in C#, using delegate nesting. Only HTML is currently implemented, therefor this document demostrates how to use SharpTemplar for writing HTML.
Central types
| Type | Description |
|---|---|
| MarkupState | The abstract representation of the markup. |
| MarkupSuccess | Markup that is correct. |
| MarkupFailure | Information on what broke the markup. |
| Attribute | Represents some SGML attribute such as 'class' or 'id' |
| ValuedAttribute | Represents some SGML attribute which has been given a value, such as 'class="container"' |
| Tag | Represents some SGML tag, such as 'div' or 'head' |
| AttributedTag | Represents som SGML tag, which has been given valued attributes |
| Element | Represents some SGML tag, which has both been given valued attrubutes and children (i.e. other Elements) |
Basic usage
To start working on some HTML, the static method HTML() should be called. This function represenst the <html> tag, and it takes its children as arguments.
- Elements starting with lower case are for adding html tags, or text.
- Elements stating with upper case are utility, e.g. conditionals and loops.
- Attributes start with '@'.
Example
var page = HTML(
head()(),
body()(
p(@class("greeting"))(
text("Hello world!")
)
)
).Build();
Creates the page:
<html>
<head/>
<body>
<p class="greeting">Hello world!</p>
</body>
</html>
SharpTemplar.HyperText is split into multiple bundles, containing the functionality need for different domains of HTML, for example lists and tables. The most usual tags, attributes etc. are contained in the static class SharpTemplar.HyperText.Base.
SharpTemplar will enforce correct HTML, i.e. tags can only be added in places where they make sense, attributes can only be applied to tags where they make sense and ids must be unique. If any of these rules are broken, a MarkupFailure will be returned, containing information on what went wrong.
Components
Sometimes you might want to create similar structures, multiple times. This can be done by nesting Elements outside of the HTML() call.
Example
Element component =
div(@class("container"))(
p()(text("Im a contained paragraph!"))
);
var page = MarkupHMTL(
head()(),
body()(
component,
component
)
).Build();
Creates the page:
<html>
<head/>
<body>
<div class="container">
<p>Im a contained paragraph!</p>
</div>
<div class="container">
<p>Im a contained paragraph!</p>
</div>
</body>
</html>
Static components might not be that interesting, but parameters can be added to them using the Func<> delegate, like in the following example.
Func<string, Element> component = (name) =>
div(@class("container"))(
p()(
text($"Hello {name}!")
)
);
var page = HTML(
head()(),
body()(
component("Bob"),
component("Alice")
)
).Build();
Creates the page:
<html>
<head/>
<body>
<div class="container">
<p>Hello Bob!</p>
</div>
<div class="container">
<p>Hello Alice!</p>
</div>
</body>
</html>
Alternativly to using a Func<> for adding parameters to a component, a method could be used.
Example
public Element component(string name) {
return div(@class("container"))(
p()(
text($"Hello {name}!")
)
);
}
var page = HTML(
head()(),
body()(
component("Bob"),
component("Alice")
)
).Build();
Creates the page:
<html>
<head/>
<body>
<div class="container">
<p>Hello Bob!</p>
</div>
<div class="container">
<p>Hello Alice!</p>
</div>
</body>
</html>
Utility Elements
If( )
Is used to conditionally add an Element or Attribute, depending on a boolean expression. If there is only provided one Element to If() nothing is applied if the boolean is false.
Example
var b = false;
var page = HTML(
head()(),
body()(
If(b, text("true"), text("false"))
)
).Build();
Creates the page:
<html>
<head/>
<body>
false
</body>
</html>
Attempt( )
Is used to apply an Element that might throw an exception, and handle those cases without crashing. This can be quite slow, as a clone of the entire markup structure is created, so that all changes made can be rolled back. If only one Element is provided, nothing is applied on an exception. Elements must be provided as Func<Element> i.e. unit functions, to delay their evaluation.
Example
Func<int, Element> component = (divident) =>
div(@class("container"))(
p().text($"{100/divident}")
);
Element failed =
div(@class("container"))(
p()(
text("Oh no!")
)
);
var page = HTML(
head()(),
body()(
Attempt(() => component(2), () => failed),
Attempt(() => component(0), () => failed)
)
).Build();
Creates the page:
<html>
<head/>
<body>
<div class="container">
<p>50</p>
</div>
<div class="container">
<p>Oh no!</p>
</div>
</body>
</html>
Range( )
Is used to apply the same Element or Func<int, Element> once for each number in the selected range.
Example
Func<int, Element> component = (number) =>
div(@class("container"))(
p()(
text($"{number}")
)
);
var page = HTML(
head()(),
body()(
Range(10, 3, component)
)
).Build();
Creates the page:
<html>
<head/>
<body>
<div class="container">
<p>10</p>
</div>
<div class="container">
<p>11</p>
</div>
<div class="container">
<p>12</p>
</div>
</body>
</html>
OnList<T>( )
Is used to apply a Func<T,Element> for each element of type T in an IEnumerable<T>.
Example
var names = new List<string>() {"Bob", "Alice"};
Func<string, Element> component = (name) =>
div(@class("container"))(
p()(
text($"Hello {name}!")
)
);
var page = HTML(
head()(),
body()(
OnList(names, component)
)
).Build();
Creates the page:
<html>
<head/>
<body>
<div class="container">
<p>Hello Bob!</p>
</div>
<div class="container">
<p>Hello Alice!</p>
</div>
</body>
</html>
