maildir2addr

Scans maildir folders for e-mail addresses, outputs unique results in aerc-style address-book-cmd format:

[E-MAIL1]\t[NAME1]\n
[E-MAIL2]\t[NAME2]\n
...

The [E-MAIL] column is forced to lowercase in the output.

Default settings store data in the $HOME/.local/share/maildir2addr directory.

A file of exclude regexes can be specified with the -e option. One regexp per line, each applied to the [E-MAIL] part only. If this file is specified but does not exist, it will be created and populated with sane defaults.

Installation

1. Install the latest Go compiler from https://golang.org/dl/
2. Install the program:

go install github.com/BourgeoisBear/maildir2addr@latest

Usage

maildir2addr [OPTION...] [MAILDIR_PATH...]

OPTIONS

  -e string
        address exclusion regex file [one per line]
         (default "$HOME/.local/share/maildir2addr/excludes.regexp")
  -i string
        address database input file
         (default "$HOME/.local/share/maildir2addr/addrs.tsv")
  -o string
        address database output file
         (default "$HOME/.local/share/maildir2addr/addrs.tsv")
  -s    process spam messages (where X-Spam-Flag == YES)
  -v    verbose, log details to STDERR

To create an address book in the default location:

maildir2addr -v /path/to/my/maildir

After issuing this command, a new tab-separated-values address file will appear at $HOME/.local/share/maildir2addr/addrs.tsv.

This file is suitable for use with the address autocomplete feature of several TUI mail clients.

NOTE: Replace $HOME with the full path to your home directory. aerc.conf does not expand environment vars for address-book-cmd.
