textutils_kernel v0.11.0 · OCaml Package

type t

two dimensional blocks of text

val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t

include Core_kernel.Invariant.S with type t := t

val invariant : t Base__.Invariant_intf.inv

val nil : t

the empty block. a left and right unit to both hcat and vcat

val fill : char -> width:int -> height:int -> t

fill and space assume width and height are non-negative

val space : width:int -> height:int -> t

type valign = [

| `Top
| `Bottom
| `Center

]

vertical and horizontal alignment specifications

type halign = [

| `Left
| `Right
| `Center

]

val text : ?align:halign -> ?max_width:int -> string -> t

a basic block of text, split on newlines and horizontally aligned as specified.

If max_width is provided, split on whitespace and wrap words to respect the request. So long as no words are longer than max_width, the resulting text block will be no wider than max_width

val textf : 
  ?align:halign ->
  ?max_width:int ->
  ('r, unit, string, t) Core_kernel.format4 ->
  'r

val vcat : ?align:halign -> ?sep:t -> t list -> t

vertical and horizontal concatenation with alignment

val hcat : ?align:valign -> ?sep:t -> t list -> t

val width : t -> int

text block dimensions

val height : t -> int

val valign : valign -> t list -> t list

vertical and horizontal sequence alignment

val halign : halign -> t list -> t list

val hstrut : int -> t

empty blocks with either horizontal or vertical extent -- useful for specifying a minimum width or height in conjunction with valign or halign, respectively

val vstrut : int -> t

val ansi_escape : ?prefix:string -> ?suffix:string -> t -> t

wrap a block with an ANSI escape sequence. The prefix and suffix arguments should render with zero width and height.

val render : t -> string

render a block of text as a string

val table : 
  ?sep_width:int ->
  [ `Cols of (t list * halign) list ] ->
  [ `Rows of t list ]

val compress_table_header : 
  ?sep_width:int ->
  [ `Cols of (t * t list * halign) list ] ->
  [ `Header of t ] * [ `Rows of t list ]

compress table header according to column widths. Input: a list of columns of the form (title, values, column alignment). Output: one header block and row sequence. Raises: if the values lists are not the same length in each column. Example:

val vsep : t

vsep = vstrut 1

val hsep : t

hsep = hstrut 1

val indent : ?n:int -> t -> t

indent ~n t = hcat [hstrut n; t]. n defaults to 2

val sexp : ('a -> Core_kernel.Sexp.t) -> 'a -> t

sexp sexp_of_a a = sexp_of_a a |> Sexp.to_string |> text
