I'm working on some deallocators now. The idea is that when Eterm
exits and memory debugging is on, several routines get called to free
the in-use memory (menus, font cache, etc.) that we still know about.
Anything left after that would be either unavoidable leaks (like
environment variables...read the putenv() man page sometime...sigh)
or genuine memory leaks that need fixing. I'm down to about 4.5K of
leftover malloc'd memory now. Making progress....
SVN revision: 3295
Okay, everything seems hunky-dorey now. If you have memory debugging
turned on, exiting Eterm will give a dump of the leftover allocated
memory including where it came from and how much there is. You'll
also get a listing of all the remaining Pixmap ID's and GC ID's along
with where they were created.
I also added some macros to the debugging stuff in libmej.h so that
if you pass the --without-debugging option to ./configure, it will
optimize out all the ASSERT and REQUIRE goop. This will make it
harder to trap bugs before they cause problems, so don't do it if you
want to help development, but if speed is critical to you, give it a
shot.

That should fix the crashes. Somehow I managed to temporarily forget
about pointer arithmetic. And somehow I thought trying to dereference
a pixmap ID would be a good thing. Sigh. I need sleep.
SVN revision: 3292
Massive reorganization/rewrite to libmej. It should now be 100%
independent of Eterm. There still may be some gremlins in the memory
debugging code, so don't use too high a number with --debug....

Marius Gedminas <mgedmin@takas.lt> reported a couple of issues back
when he was on his bug-spotting binge that I didn't have time to fix
just then. Well, now I've fixed them. ~/.Eterm/user.cfg will now
be found if there isn't a theme-specific one; this allows you to have
a single user.cfg which specifies some options you want all your
Eterms to have.
Along those same lines, the action code now searches for duplicate
bindings and changes the existing one rather than adding a new one
to the end of the list. This allows bindings in user.cfg to override
those in theme.cfg (as they should). Also, bindings are added in
reverse order, so newer ones (like in user.cfg) take precedence over
older ones (like in theme.cfg) if there is a conflict (e.g., if your
theme.cfg binds "anymod button2" and user.cfg binds "ctrl button2,"
user.cfg wins).

Okay, there are a few changes here. First off, I made multi-byte font
support the default now, as long as you have ISO 10646 fonts. In
order to do this, I made the default encoding type "Latin1" so as not
to interfere with 8-bit ISO 8859-1 characters. This means that if you
relied on the default multi-byte encoding method to be SJIS, you'll
need to update your theme files.
I also set it up so that Eterm will ignore SIGHUP, at least until I do
something with it (like reloading the theme or something).
I fixed the proportional font size algorithm. If there is more than
a 3-pixel variance between the minimum and maximum sizes for glyphs in
a proportional font, Eterm will set the size to 2 standard deviations
above the average width. This is so that they won't look so spread
out and ugly, but it still doesn't look perfect. Not much I can do on
that front...terminals must have fixed-width columns.
And then there's the biggie. I put in the ability to configure the
now-infamous font effects. I left a black drop shadow in as the
default, but you can now customize it via the --font-fx option or in
the config file using "font effects <stuff>" in the attributes
context. You can even use "fx" instead of "effects" for short.
So what goes in the <stuff> part? Well, you have several options.
To use a single-color outline, say "outline <color>". Likewise, a
single-color drop shadow is "shadow [corner] <color>"; "bottom_right"
is the default corner if you don't specify one. For a 3-D embossed
look, "emboss <dark_color> <light_color>". The opposite, a carved-
out look, can be had with "carved <dark_color> <light_color>". (Of
course, with those last two, the 3-D look will only work if you
choose the colors wisely.)
Those are all the shortcuts. The long way is to specify a series of
corner/color pairs, like "tl blue" for top-left blue, or
"bottom_right green". You can abbreviate using "tl," "tr," "bl," or
"br," or you can spell out "top_left," "top_right," "bottom_left," or
"bottom_right." If you omit a corner name, the first one defaults to
top-left, the second to top-right, and so on as listed above.

This fixes yet another resize-to-crash bug, this time with various
applications which use the secondary screen (mutt, mc, vim, etc.).
The fix is deceptively simple and does not convey the fact that it
took around 3 hours to track this bastard down. Credit to Marc Merlin
<marc@merlins.org> for first pointing this out and for helping me
track it down. And credit to Gray Watson for dmalloc, which has saved
my ass once again.

This is the first public availability of the work thus far on Eterm
0.9.1. There's quite a bit of new stuff here.
* Added scrollbar thumb support.
* Completely redid the terminfo/termcap stuff. The terminfo file is
now compiled (by tic) and installed by default (unless you specify
--without-terminfo). The config files still say xterm, though,
because some programs (like SLang and GNU mc) use the silly algorithm
of "Is $TERM set to xterm?" to detect mouse reporting support in a
terminal. =P But if you don't ever use xterm, you can use Eterm's
termcap and just name it "xterm" instead. Thanks to Marius Gedminas
<mgedmin@takas.lt> for his patch that started this whole revamp.
* Added the kEsetroot script for KDE users from Dax Games
<dgames@isoc.net>.
* You can now configure the Home and End emulation via --with-home=
and --with-end= options to configure. The --with-terminfo option is
also new, and --enable-xim is now the default.
* Added a new image state, disabled, for when Eterm loses focus. This
is supported by all widgets (well, all those that could possibly be
on screen when Eterm lost focus), even the background image. So you
could actually have all your images darken on focus out and restore
to normal on focus in.
* Widget colors formerly dealt with as colors (menu text color,
scrollbar color, etc.) are now handled by the imageclasses. Each
image state can have a foreground and background color defined. The
current exception is the background image; I hope to add that later.
The foreground is the text color and the background is the object
color (for solid color mode). So menu text color is set by the menu
imageclass. And again, for unfocused colors, use the disabled state
of the imageclass.
* Proportionally-spaced fonts are now handled much better. They are
still forced into evenly-spaced columns (it's a terminal for crying
out loud!) but at least you don't end up with Eterm's wider than your
screen. :-)
* Home on refresh is gone, as is home on echo. It's now much simpler.
There are two options: home on output, and home on input, the former
being a combination of echo and refresh. Also, keypresses that don't
necessarily have corresonding output can trigger a home on input,
like Ctrl-End or whatever...ones that don't have special meaning.
Credit to Darren Stuart Embry <dse@louisville.edu> for pointing out
this issue and the one with "m-" in font names.
* I finally got around to re-merging the new parser stuff from my
work on the Not Game. Closed up some old potential behavior quirks
with theme parsing.
* Added a new escape sequence to fork-and-exec a program. Also added
a scrollback search capability to highlight all occurances of a string
in your scrollback buffer. Use the new "Etsearch" utility to access
it. "Etsearch string" to search for a string, then "Etsearch" by
itself to reset the highlighting.
* And of course, the biggie. Eterm now supports a completely-
customizeable buttonbar. Not a menubar, a buttonbar. It can have an
arbitrary number of buttons, and each button can perform an action,
just like a menuitem. So a button could bring up a menu (like a
menubar) or launch a program (like a launchbar) or perform an
operation (like a toolbar). Each button can have an icon, text, or
both. And you can have buttons left- or right-justified in the
buttonbar. You will eventually be able to have an arbitrary number
of buttonbars, but I'm still working on that.
As with any change this big, things could very easily be broken. So
beware. :-) I have tested this myself, and everything seems to work,
but I can't test every possibility. Let me know if you find anything
that's broken, and enjoy!

Finally fixed the seg fault pointed out by Tom Gilbert
<gilbertt@tomgilbert.freeserve.co.uk> back in mid-September where
small Eterms with little or no scrollback would crash when receiving
large amounts of data all at once.
I also fixed a clearing issue with double buffering, and I worked
around a really lame gdb/glibc2 bug that has prevented me from using
gdb with Eterm for ages.
SVN revision: 1804
Once again, I've rendered old themes obselete. :-)
I added a new config file attribute and command-line parameter. The
option is --default-font-index, but I wouldn't necessarily use it.
The config file attribute makes more sense. :-)
Anyway, your themes will now need to have a line like this:
font default <index>
in the attributes section. This tells Eterm which font it should use
on startup. (<index> is a number between 0 and the highest-numbered
font you define.) You can now have up to 256 fonts. Font 0 is no
longer necessarily the default font; it is the smallest font. And the
larger the font index, the larger the font should be. (Of course,
this assumes you want Ctrl-> and Ctrl-< to increase/decrease your font
size. In reality, you can have your fonts in any order, and those
keys will cycle through them in order.)
Before, font 0 was always the default, and you didn't have much
freedom in rearranging your fonts. Plus, you were limited to 5. Not
any more. :-) The new system is much more straight-forward, logical,
and powerful.
So please be sure to update your themes by hand, or remove your theme
directory before installing this new version. If your theme lacks
the "font default" line, your Eterms will start with the wrong font.

Fixed lots of issues revealed by the -ansi -pedantic flags. The only
warnings you get with those flags now are implicit declaration
warnings for non-ANSI functions and warnings specific to certain OS's
and their non-ANSI implementations of ANSI functions, neither of
which I can do much about. :-)
SVN revision: 1010
This should get rid of all the warnings. If you're running Linux and
get warnings about setresuid, setresgid, grantpt, and unlockpt not
having prototypes, feel free to add the following lines to your copy
of /usr/include/unistd.h:
/* Linux- and HP-UX-only setres?id() calls -- mej */
extern int setresuid(uid_t ruid, uid_t euid, uid_t suid);
extern int setresgid(gid_t rgid, gid_t egid, gid_t sgid);
/* SVR4 PTY functions */
extern int grantpt(int fd);
extern int unlockpt(int fd);
SVN revision: 886
Fixed a possible null-byte overflow in the menu code.
Also, there seems to be a memory leak in XLoadQueryFont() in some
versions of XFree86 3.9.x, so I removed the unnecessary "font" lines
from the themes for the time being.
