For my client, the largest bottleneck for displaying large threads is exporting each html part individually since by default notmuch will not show the json parts. For large threads there can be quite a few parts and each must be exported and decoded one by one. Also, I then have to deal with all the crazy charsets which I can do through a library but is a pain. Therefore, this patch adds an --include-html option that causes the text/html parts to be included as part of the output of show. diff man/man1/notmuch-show.1

.TH NOTMUCH-SHOW 1 2013-08-03 "Notmuch 0.16"
|
|
.SH NAME
|
|
notmuch-show \- show messages matching the given search terms
|
|
.SH SYNOPSIS
|
|
|
|
.B notmuch show
|
|
.RI "[" options "...] <" search-term ">..."
|
|
|
|
.SH DESCRIPTION
|
|
|
|
Shows all messages matching the search terms.
|
|
|
|
See \fBnotmuch-search-terms\fR(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).

|

If true,

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

.BR text " (default for messages)"
|
|
|
|
The default plain-text format has all text-content MIME parts
|
|
decoded. Various components in the output,
|
|
.RB ( 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.

.B 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,
|
|
|
|
.B \-\-format=json
|
|
sets
|
|
.B "\-\-entire\-thread"
|
|
The caller can disable this behaviour by setting
|
|
.B \-\-entire\-thread=false

|
|
.B sexp
|
|
|
|
The output is formatted as an S-Expression (sexp). This
|
|
format is more robust than the text format for automated
|
|
processing. The nested structure of multipart MIME messages is
|
|
reflected in nested S-Expression output. By default,
|
|
S-Expression output includes all messages in a matching thread;
|
|
that is, by default,
|
|
|
|
.B \-\-format=sexp
|
|
sets
|
|
.B "\-\-entire\-thread"
|

The caller can disable this behaviour by setting

.B 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:

.BR raw " (default for a single part, see \-\-part)"
|
|
|
|
For a message or an attached message part, the original, raw content
|
|
of the email message is output. Consumers of this format should expect
|
|
to implement MIME decoding and similar functions.
|
|
|
|
For a single part (\-\-part) the raw part content is output after
|
|
performing any necessary MIME decoding. Note that messages with a
|
|
simple body still have two parts: part 0 is the whole message and part
|
|
1 is the body.
|
|
|
|
For a multipart part, the part headers and body (including all child
|
|
parts) is output.
|
|
|
|
The raw format must only be used with search terms matching single
|
|
message.

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.

Compute and report the validity of any MIME cryptographic signatures
|
|
found in the selected content (ie. "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 any MIME encrypted parts found in the selected content
|
|
(ie. "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.
|
|

Decryption expects a functioning \fBgpg-agent\fR(1) to provide any

needed credentials. Without one, the decryption will fail.

|
|
|

Specify whether to omit threads only matching search.tag_exclude 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
|
|
.B --exclude=true.
|
|

The default is
|
|
.B --exclude=true.

.B \-\-body=(true|false)
|
|

If true (the default)
|
|
.B notmuch show
|
|
includes the bodies of the messages in the output; if false,
|
|
bodies are omitted.
|
|
.B --body=false
|
|
is only implemented for the json and sexp formats and it is incompatible with
|
|
.B --part > 0.
|
|
|
|
This is useful if the caller only needs the headers as body-less
|
|
output is much faster and substantially smaller.

|
|
|
|
Include "text/html" parts as part of the output (currently only supported with
|
|
--format=json and --format=sexp).
|
|
By default, unless
|
|
.B --part=N
|
|
is used to select a specific part or
|
|
.B --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
|
|
.B 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
|
|
.B notmuch search
|
|
command.

The requested format version is too old.
