The abstract type of documents. The Show instance is equivalent to using render.

A document of height and width 1, containing a literal character.

A document of height 1 containing a literal string. text satisfies the following laws:

• text s <> text t = text (s++t)

• text "" <> x = x, if x non-empty

The side condition on the last law is necessary because text "" has height 1, while empty has no height.

An obsolete function, now identical to text.

Some text, but without any width. Use for non-printing text such as a HTML or Latex tags

int n = text (show n)

integer n = text (show n)

float n = text (show n)

double n = text (show n)

rational n = text (show n)

A ';' character

A ',' character

A : character

A space character

A '=' character

A '(' character

A ')' character

A '[' character

A ']' character

A '{' character

A '}' character

Wrap document in (...)

Wrap document in [...]

Wrap document in {...}

Wrap document in '...'

Wrap document in "..."

The empty document, with no height and no width. empty is the identity for <>, <+>, $$ and $+$, and anywhere in the argument list for sep, hcat, hsep, vcat, fcat etc.

Beside. <> is associative, with identity empty.

Beside, separated by space, unless one of the arguments is empty. <+> is associative, with identity empty.

List version of <>.

List version of <+>.

Above, except that if the last line of the first argument stops at least one position before the first line of the second begins, these two lines are overlapped. For example:

    text "hi" $$ nest 5 (text "there")

lays out as

    hi   there

rather than

    hi
         there

$$ is associative, with identity empty, and also satisfies

• (x $$ y) <> z = x $$ (y <> z), if y non-empty.

Above, with no overlapping. $+$ is associative, with identity empty.

List version of $$.

Either hsep or vcat.

Either hcat or vcat.

"Paragraph fill" version of sep.

"Paragraph fill" version of cat.

Nest (or indent) a document by a given number of positions (which may also be negative). nest satisfies the laws:

• nest 0 x = x

• nest k (nest k' x) = nest (k+k') x

• nest k (x <> y) = nest k z <> nest k y

• nest k (x $$ y) = nest k x $$ nest k y

• nest k empty = empty

• x <> nest k y = x <> y, if x non-empty

The side condition on the last law is needed because empty is a left identity for <>.

hang d1 n d2 = sep [d1, nest n d2]

punctuate p [d1, ... dn] = [d1 <> p, d2 <> p, ... dn-1 <> p, dn]

Returns True if the document is empty

Renders the document as a string using the default style.

A rendering style.
