Module `Ocolor_printf`

Printf-friendly functions

These functions are useful when trying to print with styles with Printf. However, they are a very bad choice. They perform a context-free formatting. For instance, there is no way to end the current style and restore the previous, like stack-base functions of Ocolor_format do. They just print the desired style and keep no track of the current state.

Thus, it's better to use Ocolor_format as much as possible. Moreover, Format provide a nice way of composing printers with %a and Format.asprintf. Even if you don't like boxes, Format.asprintf and semantic tags are cool.

So, here are the Printf-friendly functions. Use with care, and preferably, not at all.

fprintf

%a

val apply_style : out_channel -> Ocolor_types.style -> unit

val apply_styles : out_channel -> Ocolor_types.style list -> unit

val fg_color4 : out_channel -> Ocolor_types.color4 -> unit

val fg_color8 : out_channel -> Ocolor_types.color8 -> unit

val fg_color24 : out_channel -> Ocolor_types.color24 -> unit

val bg_color4 : out_channel -> Ocolor_types.color4 -> unit

val bg_color8 : out_channel -> Ocolor_types.color8 -> unit

val bg_color24 : out_channel -> Ocolor_types.color24 -> unit

%t

val default_fg : out_channel -> unit

val fg_rgb : int -> int -> int -> out_channel -> unit

val default_bg : out_channel -> unit

val bg_rgb : int -> int -> int -> out_channel -> unit

val reset : out_channel -> unit

sprintf

%a

val s_apply_style : unit -> Ocolor_types.style -> string

val s_apply_styles : unit -> Ocolor_types.style list -> string

Printf-like

Just like printf but perform automatic reset after printing if Ocolor_config.auto_reset is set

val fprintf : out_channel -> ('a, out_channel, unit) format -> 'a

val kfprintf : 
  (out_channel -> unit) ->
  out_channel ->
  ('a, out_channel, unit) format ->
  'a

val sprintf : ('a, unit, string, string) format4 -> 'a

val printf : ('a, out_channel, unit) format -> 'a

val kprintf : (out_channel -> unit) -> ('a, out_channel, unit) format -> 'a
