Text.Show.Pretty

Generic Haskell values. NaN and Infinity are represented as constructors. The String in the literals is the text for the literals "as is".

A chain of infix constructors means that they appeared in the input string without parentheses, i.e

1 :+: 2 :*: 3 is represented with InfixCons 1 [(":+:",2),(":*:",3)], whereas

1 :+: (2 :*: 3) is represented with InfixCons 1 [(":+:",InfixCons 2 [(":*:",3)])].

A name.

Pretty print a generic value. Our intention is that the result is equivalent to the Show instance for the original value, except possibly easier to understand by a human.

Make an Html page representing the given value.

Try to show a value, prettily. If we do not understand the value, then we just use its standard Show instance.

Convert a generic value into a pretty String, if possible.

Pretty print a generic value to stdout. This is particularly useful in the GHCi interactive environment.

Pretty print something that may be converted to a list as a list. Each entry is on a separate line, which means that we don't do clever pretty printing, and so this works well for large strucutures.

Render a value in the PrettyVal class to a Doc. The benefit of this function is that PrettyVal instances may be derived automatically using generics.

Render a value using the PrettyVal class and show it to standard out.

A class for types that may be reified into a value. Instances of this class may be derived automatically, for datatypes that support Generics.

Convert a value into an Html fragment.

Options on how to generate Html (more to come).

Default options.

Wrap an Html fragment to make an Html page.

This type is used to allow pre-processing of values before showing them.

Hide the given constructors when showing a value.

Hide the given constructors when showing a value. In addition, hide values if all of their children were hidden.

Hide constrcutros matching the given predicate. If the hidden value is in a record, we also hide the corresponding record field.

If the boolean flag is true, then we also hide constructors all of whose fields were hidden.
