Pretty printing on strings
val horiz_vertic : (unit -> 'a) -> (unit -> 'a) -> 'a
horiz_vertic h v
first calls h
to print the data horizontally,
i.e. without newlines. If the displaying contains newlines or if
its size exceeds the maximum line length (see variable line_length
below), then the function h
stops and the function v
is called
which can print using several lines.
val sprintf : ('a, unit, string) Pervasives.format -> 'a
sprintf fmt ...
formats some string like Printf.sprintf
does, except that, if it is called in the context of the *first*
function of horiz_vertic
above, it checks whether the resulting
string has chances to fit in the line. If not, i.e. if it contains
newlines or if its length is greater than max_line_length.val
,
the function gives up (raising some internal exception). Otherwise
the built string is returned.
sprintf
behaves like Printf.sprintf
if it is called in
the context of the *second* function of horiz_vertic
or without
context at all.
val line_length : int Pervasives.ref
line_length
is the maximum length (in characters) of the
line. Default = 78. Can be set to any other value before
printing.
val horizontally : unit -> bool
horizontally ()
returns the fact that the context is an
horizontal print.
