Module `Write.Without_expert`Source

Helper for converting from the old interface. Use this snippet in files to disable the expert interface:

  module Delimited = struct
    include Delimited
    module Write = Delimited.Write.Without_expert
  end

Sourcetype -'a t = 'a Delimited_kernel.Write.t

Used to describe a way to create a single row of a CSV from a given type.

Sourceval empty : 'a t

Sourceval column : ('a -> string) -> header:string -> 'a t

Source

val column_m : 
  (module Delimited_kernel__.Write_intf.To_string with type t = 'a) ->
  header:string ->
  'a t

Source

val column_opt : 
  ?default:string ->
  ('a -> string) ->
  header:string ->
  'a option t

default is printed in place of None, and if not supplied is the empty string.

Source

val column_m_opt : 
  ?default:string ->
  (module Delimited_kernel__.Write_intf.To_string with type t = 'a) ->
  header:string ->
  'a option t

Sourceval optional : ?default:string -> 'a t -> 'a option t

default is used for every column in the case of None.

Sourceval of_list : 'a t list -> 'a t

Sourceval append : 'a t -> 'a t -> 'a t

Sourceval contra_map : 'b t -> f:('a -> 'b) -> 'a t

Sourceval map_headers : 'a t -> f:(string -> string) -> 'a t

Sourceval headers : 'a t -> string list

Sourceval to_columns : 'a t -> 'a -> string list

Source

val to_string : 
  ?quote:char ->
  ?sep:char ->
  ?line_breaks:[ `Unix | `Windows ] ->
  write_header:bool ->
  'a t ->
  'a list ->
  string

Convert a list of 'a to a CSV document in a string.

Sourcemodule Fields_O = Delimited_kernel.Write.Fields_O

Open for prefix operators useful for using with Fields.to_list.

Sourcemodule O = Delimited_kernel.Write.O

Sourcemodule Out_channel = Delimited_kernel.Write.Out_channel

Wraps Stdio.Out_channel for writing CSVs one line at a time.

Source

val with_writer : 
  ?sep:char ->
  ?line_breaks:[ `Unix | `Windows ] ->
  write_header:bool ->
  'a t ->
  Async.Writer.t ->
  f:('a Async.Pipe.Writer.t -> 'b Async.Deferred.t) ->
  'b Async.Deferred.t

Make a pipe writer for 'as from a writer. The 'as will be written out as CSVs.

Once with_writer's return Deferred becomes determined, it is guaranteed that the whole CSV has hit the OS buffer.

The writer will NOT be closed when the pipe closes.

Source

val with_file : 
  ?sep:char ->
  ?line_breaks:[ `Unix | `Windows ] ->
  write_header:bool ->
  'a t ->
  string ->
  f:('a Async.Pipe.Writer.t -> 'b Async.Deferred.t) ->
  'b Async.Deferred.t

Make a pipe writer for 'as from a filename, using the given CSV converter.
