Email::Folder::Mbox - reads raw RFC822 mails from an mbox file
This isa Email::Folder::Reader - read about its API there.
Does exactly what it says on the tin - fetches raw RFC822 mails from an mbox.
The mbox format is described at http://www.qmail.org/man/man5/mbox.html
We attempt to read an mbox as through it's the mboxcl2 variant, falling back to regular mbox mode if there is no "Content-Length" header to be found.
The new constructor takes extra options.
- When filename is set to "FH" than Email::Folder::Mbox will read mbox archive from filehandle "fh" instead from disk file "filename".
- This indicates what the line-ending style is to be. The default is "\n", but for handling files with mac line-endings you would want to specify "eol => "\x0d""
- The value is taken as a boolean that governs what is used match as a
If false we use the mutt style
/^From \S+\s+(?:Mon|Tue|Wed|Thu|Fri|Sat|Sun)/ /^From (?:Mon|Tue|Wed|Thu|Fri|Sat|Sun)/;
If true we use
In deference to this extract from <http://www.jwz.org/doc/content-length.html>
Essentially the only safe way to parse that file format is to consider all lines which begin with the characters ``From '' (From-space), which are preceded by a blank line or beginning-of-file, to be the division between messages. That is, the delimiter is "\n\nFrom .*\n" except for the very first message in the file, where it is "^From .*\n". Some people will tell you that you should do stricter parsing on those lines: check for user names and dates and so on. They are wrong. The random crap that has traditionally been dumped into that line is without bound; comparing the first five characters is the only safe and portable thing to do. Usually, but not always, the next token on the line after ``From '' will be a user-id, or email address, or UUCP path, and usually the next thing on the line will be a date specification, in some format, and usually there's nothing after that. But you can't rely on any of this.
Defaults to false.
- This boolean value indicates whenever lines which starts with
should be unescaped (= removed leading '>' char). This is needed for mboxrd and mboxcl variants. But there is no way to detect for used mbox variant, so default value is false.
- Seek to an offset when opening the mbox. When used in combination with ->tell you may be able to resume reading, with a trailing wind.
- This returns next message as string
- This returns next message as ref to string
- This returns the current filehandle position in the mbox.
- This returns the From_ line for next message. Call it before ->next_message.
- This returns the messageid of last read message. Call if after ->next_message.
