v0.3

Ezbl version 0.3
Continuing the trend of massive upgrades, this release brings with it some of
the biggest changes yet!

User-visible Changes:

* Automatically-resizing xwidgets

  If you change the size of the window containing a browser window, Ezbl will
  automatically resize the xwidget to fit the new size.

* Cookie handler

  Ezbl is now able to honor cookie PUT and GET requests from Uzbl, using Uzbl's
  (relatively) new "talk_to_socket" system. This means that it is not having to
  spawn a Python process for each and every cookie on every page you visit, but
  is talking over a UNIX domain socket (which is fast).

  This, combined with the new event system has enabled the following:

* No more handler.py script

  Ezbl is now 100% Emacs Lisp, and does not need to launch external processes
  (aside from Uzbl, of course :). This is largely achieved through the new
  event-manager system, which lets Uzbl notify Ezbl of changes and events over
  Standard Output, making for a very quick communication.

* Much faster performance

  This is largely related to the event and cookie handlers, but it bears
  repeating. In a few tests of loading yahoo.com, Ezbl would take about 30
  seconds to finish loading the page. That time has now shrunk to just over 2.5
  seconds. By using the event manager to let Uzbl notify us of changes, rather
  than querying and polling, the amount of dead-time has decreased
  dramatically. One commit in particular (d99f336) is responsible for the
  majority of this speedup.

* New Emacs dependency

  Uzbl uses a special kind of socket type (SOCK_SEQPACKET) for its cookie
  handlers, and Emacs doesn't support such sockets (before 23.2, which I helped
  to add), so you will need to build a custom version of Emacs, available here:

  http://github.com/dhax/emacs

  Note that you need the "xembed" branch of that repository.

Internal Changes:

* `ezbl-inst' (formerly `ezbl-instances') is now a CL struct

  ezbl-inst is now defined by a defstruct from the CL (Common Lisp)
  package. This cut down on a lot of the boring and redundant checking and
  verifying code.

  Also note that in an effort to save those precious electrons, all occurrences
  of `ezbl-instance' have been replaced with `ezbl-inst'.

* Restructured naming system

  In order to better align with the Emacs convention of getting fake namespaces
  with variable prefixes, the function and variable names have been changed to
  adhere to a more "least-to-most specific" pattern. That is, what used to be
  `ezbl-get-inst' is now `ezbl-inst-get', so that it shows up next to
  `ezbl-inst-p' when sorted alphabetically. This is mostly a cosmetic change, so
  a simple find and replace will fix any compatibility issues.

* Much less use of `ezbl-sync-request'

  It was one of the biggest culprits in slowing down the operation of Ezbl,
  since it has to repeatedly scan for matching regular expressions. Variables
  are now handled by keeping a hashtable of the variable names

v0.2

Ezbl version 0.2
This marks the first release that is actually somewhat usable for regular
browsing, as

User-visible changes:

* Most Ezbl commands are interactive

  Commands such as `ezbl-command-uri' or `ezbl-command-back' are now
  interactive, and so can be invoked through "M-x" or bound to keys.

  They are invoked with the "inst" argument set to `nil', which causes them to
  look in the current buffer for an `ezbl-instance' variable. This means that
  they will work as expected in Ezbl display buffers.

* Ezbl major mode

  Ezbl display buffers are now read-only and are have the major mode
  `ezbl-mode'.

* Add key bindings for Ezbl commands

  The interactive Ezbl commands now have default key bindings, making navigation
  much easier.

* Clean up mode-line

  The mode-line now looks more like the regular Emacs default, with the page
  name in bold and the URI separated from the page name by spaces. Also, display
  of the major mode now works properly.

v0.1.2

Ezbl version 0.1.2
User-visible changes:

* Handler script for Uzbl callbacks.

  Emacs can now implement handlers for cookies, history, downloads, and so
  on. Currently, the handlers are unused.

* Buffer names

  The display and output buffers are now called "*ezbl-display-1234*" and
  "*ezbl-output-1234*", respectively, for a Uzbl process with the pid
  "1234". This may be more cumbersome when attempting to select a particular
  display buffer by name, but other selection methods could be used. This
  decision may be revisited.

* Remove "name" property from ezbl instances

  Since there is really no string identifier which will persist for the duration
  of an instance, abandon the "name" field altogether. The process id is used to
  distinguish instances instead.

* Hide the output buffer from the buffer listing

  The user will not need to look at the output buffer (which captures the stdout
  of the Uzbl process), so hide it from display. This also disables undo
  recording of the buffer, which should save some memory.

* Use an Ezbl-specific mode line

  The mode line is modified to display the current page title and URI. This
  display is updated whenever Emacs decides to recompute the mode line (which
  seems to be fairly often).

Internal changes:

* Ezbl instances

  They now contain the arguments passed to the Uzbl command line, the process
  object, the pid, and the output and display buffers.

** Getting and setting

   Rather than manually accessing the fields of the instance alist, a family of
   functions has been created to handle getting and setting the values of the
   instance.

* Allow `ezbl-get-instance' to search for a pid.

  If the argument provided is an integer, checks `ezbl-instances' for an
  instance with a matching pid.

v0.1.1

Version 0.1.1
Add the `ezbl-open' function to create a buffer, embed a Uzbl window, and switch to it.

v0.1

Version 0.1
Just barely supports embedding a Uzbl window in a buffer, not much else for now.
Something went wrong with that request. Please try again.
