`notmuch' `show' [`option' ...] <`search-term'> ...

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

Shows all messages matching the search terms.

See `notmuch-search-terms(7)' for details of the supported syntax for
<search-terms>.

The messages will be grouped and sorted based on the threading (all
replies to a particular message will appear immediately after that
message in date order). The output is not indented by default, but depth
tags are printed so that proper indentation can be performed by a
post-processor (such as the emacs interface to notmuch).

Supported options for `show' include

`--entire-thread=(true|false)'
     If true, `notmuch show' outputs all messages in the thread of any
     message matching the search terms; if false, it outputs only the
     matching messages. For `--format=json' and `--format=sexp' this
     defaults to true. For other formats, this defaults to false.

`--format=(text|json|sexp|mbox|raw)'

    `text' (default for messages)
          The default plain-text format has all text-content MIME parts
          decoded. Various components in the output, (`message',
          `header', `body', `attachment', and MIME `part'), will be
          delimited by easily-parsed markers. Each marker consists of a
          Control-L character (ASCII decimal 12), the name of the
          marker, and then either an opening or closing brace, ('{' or
          '}'), to either open or close the component. For a multipart
          MIME message, these parts will be nested.

    `json'
          The output is formatted with Javascript Object Notation
          (JSON). This format is more robust than the text format for
          automated processing. The nested structure of multipart MIME
          messages is reflected in nested JSON output. By default JSON
          output includes all messages in a matching thread; that is, by
          default, `--format=json' sets `--entire-thread'. The caller
          can disable this behaviour by setting
          `--entire-thread=false'.  The JSON output is always encoded
          as UTF-8 and any message content included in the output will
          be charset-converted to UTF-8.

    `sexp'
          The output is formatted as the Lisp s-expression (sexp)
          equivalent of the JSON format above. Objects are formatted as
          property lists whose keys are keywords (symbols preceded by a
          colon). True is formatted as `t' and both false and null are
          formatted as `nil'. As for JSON, the s-expression output is
          always encoded as UTF-8.

    `mbox'
          All matching messages are output in the traditional, Unix mbox
          format with each message being prefixed by a line beginning
          with "From " and a blank line separating each message. Lines
          in the message content beginning with "From " (preceded by
          zero or more '>' characters) have an additional '>' character
          added. This reversible escaping is termed "mboxrd" format and
          described in detail here:

               <http://homepage.ntlworld.com/jonathan.deboynepollard/FGA/mail-mbox-formats.html>

    `raw' (default if `--part' is given)
          Write the raw bytes of the given MIME part of a message to
          standard out. For this format, it is an error to specify a
          query that matches more than one message.

          If the specified part is a leaf part, this outputs the body of
          the part after performing content transfer decoding (but no
          charset conversion). This is suitable for saving attachments,
          for example.

          For a multipart or message part, the output includes the part
          headers as well as the body (including all child parts). No
          decoding is performed because multipart and message parts
          cannot have non-trivial content transfer encoding. Consumers
          of this may need to implement MIME decoding and similar
          functions.

`--format-version=N'
     Use the specified structured output format version. This is
     intended for programs that invoke `notmuch(1)' internally. If
     omitted, the latest supported version will be used.

`--part=N'
     Output the single decoded MIME part N of a single message. The
     search terms must match only a single message. Message parts are
     numbered in a depth-first walk of the message MIME structure, and
     are identified in the 'json', 'sexp' or 'text' output formats.

     Note that even a message with no MIME structure or a single body
     part still has two MIME parts: part 0 is the whole message
     (headers and body) and part 1 is just the body.

`--verify'
     Compute and report the validity of any MIME cryptographic
     signatures found in the selected content (e.g., "multipart/signed"
     parts). Status of the signature will be reported (currently only
     supported with `--format=json' and `--format=sexp'), and the
     multipart/signed part will be replaced by the signed data.

`--decrypt=(false|auto|true|stash)'
     If `true', decrypt any MIME encrypted parts found in the selected
     content (e.g., "multipart/encrypted" parts). Status of the
     decryption will be reported (currently only supported with
     `--format=json' and `--format=sexp') and on successful decryption
     the multipart/encrypted part will be replaced by the decrypted
     content.

     `stash' behaves like `true', but upon successful decryption it
     will also stash the message's session key in the database, and
     index the cleartext of the message, enabling automatic decryption
     in the future.

     If `auto', and a session key is already known for the message,
     then it will be decrypted, but notmuch will not try to access the
     user's keys.

     Use `false' to avoid even automatic decryption.

     Non-automatic decryption (`stash' or `true', in the absence of a
     stashed session key) expects a functioning `gpg-agent(1)' to
     provide any needed credentials. Without one, the decryption will
     fail.

     Note: setting either `true' or `stash' here implies `--verify'.

     Here is a table that summarizes each of these policies:

                                  false       auto       true       stash
     --------------------------------------------------------------------------- 
     Show cleartext if session                X          X          X
     key is already known                                           
     Use secret keys to show                             X          X
     cleartext                                                      
     Stash any newly recovered                                      X
     session keys, reindexing                                       
     message if found                                               

     Note: `--decrypt=stash' requires write access to the database.
     Otherwise, `notmuch show' operates entirely in read-only mode.

     Default: `auto'

`--exclude=(true|false)'
     Specify whether to omit threads only matching search.exclude_tags
     from the search results (the default) or not. In either case the
     excluded message will be marked with the exclude flag (except when
     output=mbox when there is nowhere to put the flag).

     If `--entire-thread' is specified then complete threads are
     returned regardless (with the excluded flag being set when
     appropriate) but threads that only match in an excluded message
     are not returned when `--exclude=true.'

     The default is `--exclude=true.'

`--body=(true|false)'
     If true (the default) `notmuch show' includes the bodies of the
     messages in the output; if false, bodies are omitted.
     `--body=false' is only implemented for the text, json and sexp
     formats and it is incompatible with `--part > 0.'

     This is useful if the caller only needs the headers as body-less
     output is much faster and substantially smaller.

`--include-html'
     Include "text/html" parts as part of the output (currently only
     supported with `--format=text', `--format=json' and
     `--format=sexp'). By default, unless `--part=N' is used to select
     a specific part or `--include-html' is used to include all
     "text/html" parts, no part with content type "text/html" is
     included in the output.

A common use of `notmuch show' is to display a single thread of email
messages. For this, use a search term of "thread:<thread-id>" as can be
seen in the first column of output from the `notmuch search' command.
