Before the change, citation and signature wash buttons used the
same label in both visible and hidden states. Sometimes it is
very convenient when you can determine if the text is hidden or
shown without reading the context and/or clicking the button.
The patch makes it easy to see if the text is shown or hidden by
explicitly saying what the button does (shows or hides the text).
The removed expressions, which were used to ensure that citations were
both preceded and followed by a blank line, were poorly implemented
and caused a regexp stack overflow on messages more than a few
thousand lines long.
Detect inline patches and convert them to fake attachments, in order
that `diff-mode' highlighting can be applied to the patch. This can be
enabled by customising `notmuch-show-insert-text/plain-hook'.
Add:
- notmuch-wash-wrap-long-lines: Wrap lines longer than the width of
the current window whilst maintaining any citation prefix.
- notmuch-wash-tidy-citations: Tidy up citations by:
- compress repeated otherwise blank citation lines,
- remove otherwise blank citation lines at the head and tail of a
citation,
- notmuch-wash-elide-blank-lines: Compress repeated blank lines and
remove leading and trailing blank lines.
None of these is enabled by default - add them to
`notmuch-show-insert-text/plain-hook' to use.
Reviewed-by: Carl Worth <cworth@cworth.org>: I previously committed a
stale version of this patch.
Add:
- notmuch-wash-wrap-long-lines: Wrap lines longer than the width of
the current window whilst maintaining any citation prefix.
- notmuch-wash-tidy-citations: Tidy up citations by:
- compress repeated otherwise blank citation lines,
- remove otherwise blank citation lines at the head and tail of a
citation and remove blank lines between attribution statements and
the citation,
- notmuch-wash-compress-blanks: Compress repeated blank lines and
remove leading and trailing blank lines.
Enable `notmuch-wash-tidy-citations' and
`notmuch-wash-compress-blanks' by default by adding them to
`notmuch-show-insert-text/plain-hook'. `notmuch-wash-wrap-long-lines'
is not enabled by default.
If `notmuch-wash-wrap-long-lines' is enabled, word wrapping of the
buffer leads to an unappealing display of text, so provide a function
to disable it and add it to the list of `notmuch-show-mode' hook
functions.
Add an `isearch-open-invisible' property to the overlays used to hide
citations and signatures, together with an appropriate function to
leave the invisible text visible should that be required.
