Each line has the + form + +<encoded-tag> +<encoded-tag> ... -- id:<quoted-mesâ + sage-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 sinâ + gle 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|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 seperated key-value + pair. Both key and value are hex encoded if needed. + + tags + Output per-message metadata, namely tags. See format above + for description of the output. + + The default is to include both tags and configuration informaâ + tion. As of version 2 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.
