This new command allows the user to interactively choose a different
duplicate (file) to display for a given message in
notmuch-show-mode. Since both tree and unthreaded view use
notmuch-show-mode, this provides the same facility there.
This parameter was originally introduced to hide large attachements
that happened to be text/plain. From a performance point of view,
there is no reason not to also hide large message bodies.
This leverages the machinery already there to insert buttons for
attachments.
A potential use-case is browsing the top layers of the tree to decide
which of the lower subtrees to read.
Having notmuch-show-next-thread return non-nil on success and nil on
failure makes it easier for users to interact with notmuch via elisp.
This commit changes notmuch-search-show-thread too since the return
value of notmuch-show-next-thread depends on notmuch-search-show-thread.
Amended by db: fix whitespace in T450-emacs-show
This variable is important for people who want to change the default
behaviour when displaying multipart/alternative messages. Previously
it was undocumented. Add a defcustom to help users and copy some
documentation from the wiki. The usual machinery of re-using
docstrings is a bit tricky to use here because it mangles the example
lisp code, and the link to the info node should not be in e.g. the
html page.
Add a simple test to make sure the switch from defvar to defcustom did
not break something obvious.
The remaining problem in this test is fixed upstream in Emacs
28. While most people are using earlier versions of emacs, the test
still provides some documentation of a known bug.
There are at least 3 bugs present.
1) notmuch-show-insert-part-message/rfc822 assumes that message/rfc822
parts will have a ":content" property, but that turns out not to be
the case.
2) something deep in gnus wants gnus-newsgroup-charset, but that is
defined in gnus-sum, which is not loaded by default.
3) If gnus-sum is loaded, then the display of the message/rfc822 part
succeeds, but the buffer gets put into gnus-article-mode, which means
that, inter alia, notmuch text properties and keybindings get wiped.
This is a bit of a cheat, since the format does not actually
change. On the other hand it is fairly common to do something like
this to shared libary SONAMEs when the ABI changes in some subtle way.
It does rely on the format-version argument being early enough on the
command line to generate a sensible error message.
Sourcing test-lib.sh will cd to TMP_DIRECTORY, so
relative path in $0 will not work in previous version
. $(dirname "$0")/test-lib-emacs.sh
Now individual test scripts -- e.g. ./test/T310-emacs.sh
will work.
Starting with Emacs 27 the old `cl' implementation is finally
considered obsolete. Previously its use was strongly discouraged
at run-time but one was still allowed to use it at compile-time.
For the most part the transition is very simple and boils down to
adding the "cl-" prefix to some symbols. A few replacements do not
follow that simple pattern; e.g. `first' is replaced with `car',
even though the alias `cl-first' exists, because the latter is not
idiomatic emacs-lisp.
In a few cases we start using `pcase-let' or `pcase-lambda' instead
of renaming e.g. `first' to `car'. That way we can remind the reader
of the meaning of the various parts of the data that is being
deconstructed.
An obsolete `lexical-let' and a `lexical-let*' are replaced with their
regular variants `let' and `let*' even though we do not at the same
time enable `lexical-binding' for that file. That is the right thing
to do because it does not actually make a difference in those cases
whether lexical bindings are used or not, and because this should be
enabled in a separate commit.
We need to explicitly depend on the `cl-lib' package because Emacs
24.1 and 24.2 lack that library. When using these releases we end
up using the backport from GNU Elpa.
We need to explicitly require the `pcase' library because
`pcase-dolist' was not autoloaded until Emacs 25.1.
We did not have a test showing what message decryption looks like
within notmuch-emacs. This change gives us a baseline for future work
on the notmuch-emacs interface.
This differs from previous revisions of this patch in that it should
be insensitive to the order in which the local filesystem readdir()s
the underlying maildir.

We also expand tab completion for it, update the emacs bindings, and
update T350, T357, and T450 to match.
Make use of the bool-to-keyword backward-compatibility feature.
This test will pass if either the notmuch show mitigation code is
working correctly, or upstream emacs mime handling code has it's own
fix for https://bugs.gnu.org/28350.
There are some cases like remote usage where this might cause
problems, but those users can easily customize the variable. The
inconvenience seems to be outweighed by the security benefit for most
users.
Since the error field is unused by the emacs front end, no changes are
needed other than bumping the format version number.
As it is, this is a bit overengineered, but it will reduce duplication
when we support gmime 3.0
The files (test) scripts source (with builtin command `.`) provides
information which the scripts depend, and without the `source` to
succeed allowing script to continue may lead to dangerous situations
(e.g. rm -rf "${undefined_variable}"/*).
At the end of all source (.) lines construct ' || exit 1' was added;
In our case the script script will exit if it cannot find (or read) the
file to be sourced. Additionally script would also exits if the last
command of the sourced file exited nonzero.
In emacs 24.4 the messages buffer starts being read-only, which kills
these tests. This seems to be the point of the variable
inihibit-read-only, which has existed at least since emacs 21.
All test scripts to be executed are now named as T\d\d\d-name.sh,
numers in increments of 10.
This eases adding new tests and developers to see which are test scripts
that are executed by test suite and in which order.
