`notmuch' `dump' [-format=(batch-tag|sup)] [-output=<`file'>] [-]
[<`search-term'> ...]

2 DESCRIPTION
*************

Dump tags for messages matching the given search terms.

Output is to the given filename, if any, or to stdout.

These tags are the only data in the notmuch database that can't be
recreated from the messages themselves. The output of notmuch dump is
therefore the only critical thing to backup (and much more friendly to
incremental backup than the native database files.)

See `notmuch-search-terms(7)' for details of the supported syntax for
<search-terms>. With no search terms, a dump of all messages in the
database will be generated. A `--' argument instructs notmuch that the
remaining arguments are search terms.

Supported options for `dump' include

`--format=(sup|batch-tag)'
     Notmuch restore supports two plain text dump formats, both with
     one message-id per line, followed by a list of tags.

    `batch-tag'
          The default `batch-tag' dump format is intended to more
          robust against malformed message-ids and tags containing
          whitespace or non-`ascii(7)' characters. Each line has the
          form:

              +<*encoded-tag*\ > +<*encoded-tag*\ > ... -- id:<*quoted-message-id*\ >

          Tags are hex-encoded by replacing every byte not matching the
          regex `[A-Za-z0-9@=.,_+-]' with `%nn' where nn is the two
          digit hex encoding. The message ID is a valid Xapian query,
          quoted using Xapian boolean term quoting rules: if the ID
          contains whitespace or a close paren or starts with a double
          quote, it must be enclosed in double quotes and double quotes
          inside the ID must be doubled. The astute reader will notice
          this is a special case of the batch input format for
          `notmuch-tag(1)'; note that the single message-id query is
          mandatory for `notmuch-restore(1)'.

    `sup'
          The `sup' dump file format is specifically chosen to be
          compatible with the format of files produced by sup-dump. So
          if you've previously been using sup for mail, then the
          `notmuch restore' command provides you a way to import all of
          your tags (or labels as sup calls them). Each line has the
          following form:

              <*message-id*\ > **(** <*tag*\ > ... **)**

          with zero or more tags are separated by spaces. Note that
          (malformed) message-ids may contain arbitrary non-null
          characters. Note also that tags with spaces will not be
          correctly restored with this format.

`--include=(config|properties|tags)'
     Control what kind of metadata is included in the output.

    `config'
          Output configuration data stored in the database. Each line
          starts with "#@ ", followed by a space separated key-value
          pair.  Both key and value are hex encoded if needed.

    `properties'
          Output per-message (key,value) metadata.  Each line starts
          with "#= ", followed by a message id, and a space separated
          list of key=value pairs.  Ids, keys and values are hex encoded
          if needed.  See `notmuch-properties(7)' for more details.

    `tags'
          Output per-message boolean metadata, namely tags. See
          `format' above for description of the output.

     The default is to include all available types of data.  The option
     can be specified multiple times to select some subset. As of
     version 3 of the dump format, there is a header line of the
     following form:

         #notmuch-dump <*format*>:<*version*> <*included*>

     where <`included'> is a comma separated list of the above options.

`--output='<filename>
     Write output to given file instead of stdout.
