Previously, all visibility in show buffers for headers, message bodies, and washed text was specified by generating one or more symbols for each region and creating overlays with their 'invisible property set to carefully crafted combinations of these symbols. Visibility was controlled not by modifying the overlays directly, but by adding and removing the generated symbols from a gigantic buffer invisibilty spec. This has myriad negative consequences. It's slow because Emacs' display engine has to traverse the buffer invisibility list for every overlay and, since every overlay has its own symbol, this makes rendering O(N^2) in the number of overlays. It composes poorly because symbol-type 'invisible properties are taken from the highest priority overlay over a given character (which is often ambiguous!), rather than being gathered from all overlays over a character. As a result, we have to include symbols related to message hiding in the wash code lest the wash overlays un-hide parts of hidden messages. It also requires various workarounds for isearch to properly open overlays, to set up buffer-invisibility-spec for remove-from-invisibility-spec to work right, and to explicitly refresh the display after updating the buffer invisibility spec. None of this is necessary. This patch converts show and wash to use simple boolean 'invisible properties and to not use the buffer invisibility spec. Rather than adding and removing generated symbols from the invisibility spec, the code now directly toggles the 'invisible property of the appropriate overlay. This speeds up rendering because the display engine only has to check the boolean values of the overlays over a character. It composes nicely because text will be invisible if *any* overlay over it has 'invisible t, which means we can overlap invisibility overlays with abandon. We no longer need any of the workarounds mentioned above. And it fixes a minor bug for free: now, when isearch opens a washed region, the button text will update to say "Click/Enter to hide" rather than remaining unchanged. |

Notmuch - thread-based email index, search and tagging. Notmuch is a system for indexing, searching, reading, and tagging large collections of email messages in maildir or mh format. It uses the Xapian library to provide fast, full-text search with a convenient search syntax. Notmuch is free software, released under the GNU General Public License version 3 (or later). Building notmuch ---------------- See the INSTALL file for notes on compiling and installing notmuch. Running notmuch --------------- After installing notmuch, start by running "notmuch setup" which will interactively prompt for configuration information such as your name, email address, and the directory which contains your mail archive to be indexed. You can change any answers later by running "notmuch setup" again or by editing the .notmuch-config file in your home directory. With notmuch configured you should next run "notmuch new" which will index all of your existing mail. This can take a long time, (several hours) if you have a lot of email, (hundreds of thousands of files). When new mail is delivered to your mail archive in the future, you will want to run "notmuch new" again. These runs will be much faster as they will only index new messages. Finally, you can prove to yourself that things are working by running some command-line searches such as "notmuch search from:someone@example.com" or "notmuch search subject:topic". See "notmuch help search-terms" for more details on the available search syntax. The command-line search output is not expected to be particularly friendly for day-to-day usage. Instead, it is expected that you will use an email interface that builds on the notmuch command-line tool or the libnotmuch library. Notmuch installs a full-featured email interface for use within emacs. To use this, first add the following line to your .emacs file: (require 'notmuch) Then, either run "emacs -f notmuch" or execute the command "M-x notmuch" from within a running emacs. If you're interested in a non-emacs-based interface to notmuch, then please join the notmuch community. Various other interfaces are already in progress, (an interface within vim, a curses interface, graphical interfaces based on evolution, and various web-based interfaces). The authors of these interfaces would love further testing or contribution. See contact information below.
