Module OpamParserTypes.FullPosSource

OpamParserTypes transitional module with full position types

Sourcetype file_name = string

Source file positions

Sourcetype pos = {
  1. filename : file_name;
  2. start : int * int;
  3. stop : int * int;
}

Full position

Sourcetype 'a with_pos = {
  1. pelem : 'a;
  2. pos : pos;
}

with_pos type, used for all units, embedding the element pelem ans its position pos

Base values

Sourcetype opamfile_section = {
  1. section_kind : string with_pos;
    (*

    Section kind (e.g. extra-source)

    *)
  2. section_name : string with_pos option;
    (*

    Section name (e.g. "myfork.patch")

    *)
  3. section_items : opamfile_item list with_pos;
    (*

    Content of the section

    *)
}

An opamfile section

Sourceand opamfile_item_kind =
  1. | Section of opamfile_section
    (*

    e.g. kind ["name"] { ... }

    *)
  2. | Variable of string with_pos * value
    (*

    e.g. opam-version: "2.0"

    *)

An opamfile is composed of sections and variable definitions

Sourcetype opamfile = {
  1. file_contents : opamfile_item list;
    (*

    Content of the file

    *)
  2. file_name : file_name;
    (*

    Name of the disk file this record was loaded from

    *)
}

A file is a list of items and the filename
