-- This package provides a parser that creates an email message from a textual
-- representation of it.

package GNATCOLL.Email.Parser is
procedure Parse (Str : String; Msg : out Message);
-- Default message parser
procedure Parse_Ignore_Headers (Str : String; Msg : out Message);
-- Same as Parse, but the headers are not stored into the final Msg.
-- This significantly speeds up the parser, and should be used if you don't
-- need access to headers later on.
procedure Parse_Minimal_Headers (Str : String; Msg : out Message);
-- Same as Parse, but only keep a subset of the headers. This removes
-- headers like 'Received:', which are generally not useful to manipulate
-- the message.
procedure Parse_No_Payload (Str : String; Msg : out Message);
-- Parse the message, but store its body unparsed (ie nested parts are
-- not analyzed).
procedure Parse_No_Payload_Minimal_Headers
(Str : String; Msg : out Message);
-- Parse the message, but store its body unparsed (ie nested parts are
-- not analyzed). Ignore headers that are generally not useful to
-- manipulate a message.
type Header_Filter is access function (Name : String) return Boolean;
procedure Full_Parse

Store_Headers : Boolean := True;

Parse_Payload : Boolean := True;
Filter : Header_Filter := null);
-- Internal version of Parse. You could implement your own Parse by
-- calling this one with the appropriate parameters. For instance, you
-- can choose the list of headers to store.
-- If Store_Headers is false, then the headers will not be stored in the
-- final message. Some of them are still taken into account to properly
-- parse the message (MIME contents,...). This significantly speeds up the
-- processing since less memory needs to be allocated.
-- If Filter is specified, only those headers matching Filter will be
-- stored. If Store_Headers is False, no header is stored.
-- If Store_Payload is False, then the payload is not analyzed nor parsed,
-- simply ignored. When the payload is stored, it can additionally be
-- parsed, ie when it is a multipart message, each of the part is
-- extracted separately. To save time, they are not MIME-decoded though.
procedure Full_Parse_From_File
(Filename : GNATCOLL.VFS.Virtual_File;
Msg : out Message;

Store_Payload : Boolean := True;
Parse_Payload : Boolean := True;
Filter : Header_Filter := null);
-- Same as Full_Parse, but reads the message directly from a file.
-- Name_Error is raised if the file could not be read.
