Sphinx-doc already formats the terms appropriately for a given backend (bold in html and man). `makeinfo` complains noisily about formatting inside a @item if we add our own explicit formatting. This change may change the formatting in the info output. On the other hand, the existing use of quotes for bold is not that great anyway. In some places blank lines were removed to preserve the logical structure of a definition list.

SYNOPSIS
|
|
========
|
|
|
|
**notmuch** **show** [*option* ...] <*search-term*> ...
|
|
|
|
DESCRIPTION
|
|
===========
|
|
|
|
Shows all messages matching the search terms.
|
|
|
|
See :any:`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
|
|
|
|
.. program:: show
|
|
|
|
.. option:: --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.
|
|
|
|
.. option:: --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.
|
|
|
|
.. option:: --format-version=N
|
|
|
|
Use the specified structured output format version. This is
|
|
intended for programs that invoke :any:`notmuch(1)` internally. If
|
|
omitted, the latest supported version will be used.
|
|
|
|
.. option:: --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.
|
|
|
|
.. option:: --sort=(newest-first|oldest-first)
|
|
|
|
This option can be used to present results in either chronological
|
|
order (**oldest-first**) or reverse chronological order
|
|
(**newest-first**).
|
|
|
|
Only threads as a whole are reordered. Ordering of messages within
|
|
each thread will not be affected by this flag, since that order is
|
|
always determined by the thread's replies.
|
|
|
|
By default, results will be displayed in reverse chronological
|
|
order, (that is, the newest results will be displayed first).
|
|
|
|
.. option:: --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.
|
|
|
|
.. option:: --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 :manpage:`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 | | X | X | X |
|
|
| session key is | | | | |
|
|
| already known | | | | |
|
|
+------------------------+-------+------+------+-------+
|
|
| Use secret keys to | | | X | X |
|
|
| show cleartext | | | | |
|
|
+------------------------+-------+------+------+-------+
|
|
| Stash any newly | | | | X |
|
|
| recovered 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``
|
|
|
|
.. option:: --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.``
|
|
|
|
.. option:: --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.
|
|
|
|
.. option:: --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
|
|
:any:`notmuch-search(1)` command.
|
|
|
|
EXIT STATUS
|
|
===========
|
|
|
|

|
|
|
|
``20``
|
|
The requested format version is too old.
|
|
|
|
``21``
|
|
The requested format version is too new.
