formatter [Format] | Abstract data corresponding to a pretty-printer (also called a formatter) and all its machinery.
formatter_out_functions [Format] | The set of output functions specific to a formatter: the `out_string` function performs all the pretty-printer string output. It is called with a string `s`, a start position `p`, and a number of characters `n`; it is supposed to output characters `p` to `p + n - 1` of `s`., the `out_flush` function flushes the pretty-printer output device., `out_newline` is called to open a new line when the pretty-printer splits the line., the `out_spaces` function outputs spaces when a break hint leads to spaces instead of a line split. It is called with the number of spaces to output., the `out_indent` function performs new line indentation when the pretty-printer splits the line. It is called with the indentation value of the new line. By default: fields `out_string` and `out_flush` are output device specific; (e.g. `output_string` and `flush` for a `out_channel` device, or `Buffer.add_substring` and `ignore` for a `Buffer.t` output device),, field `out_newline` is equivalent to `out_string "\n" 0 1`;, fields `out_spaces` and `out_indent` are equivalent to `out_string (String.make n ' ') 0 n`.
formatter_tag_functions [Format] | The semantic tag handling functions specific to a formatter: `mark` versions are the 'tag-marking' functions that associate a string marker to a tag in order for the pretty-printing engine to write those markers as 0 length tokens in the output device of the formatter.
