their XML wrapper/animation file. They can access their /ai/models node
via cmdarg() function. Example:
<nasal>
<load>
print("Hi, I'm the Nimitz. My data are under ",
cmdarg().getPath());
</load>
<unload>
...
</unload>
</nasal>
Note, however, that the <unload> block is only called on exit at the moment,
not when the tile is unloaded.

"Flight plans" which can start at a given time (gmt)
WAITUNTIL tokens which pause the flight plans until a given time (gmt)
Submodels can now be attached to any AI objects (except submodels - it can
be done, but in my experimental code it's too expensive in frame rate atm)
"No-roll" attribute added to Ballistic objects - useful for wakes and the
like
"Random" attribute added to Ballistic objects (adds =- 5% to the Cd) -
useful for smoke, exhausts
If the <trigger> tag is not specified the Ballistic object/s will be
released at start-up (cannot be stopped)
Submodels are not released from AI Objects if the AI Object is more than 15
miles away.
"""
mf: minor code and formatting fixes; submodels.?xx were FUBAR and are thus
astyle formatted;
NOTE that <name> tags END, EOF, WAIT, WAITUNTIL are *depreciated*.
Don't get too used to them. This will have to be moved from the "name"
to regular engries.
Nasal now supports calls to "subcontexts" and errors can be thrown
across them, leading to complete stack traces when call() is used,
instead of the truncated ones we now see.
Vectors can now be concatenated using the ~ operator that used to work
only for strings.
Better runtime error messages in general due to a fancier
naRuntimeError() implementation
A big data size shrink on 64 bit systems; the size of a naRef dropped
by a factor of two.
"Braceless code blocks" have been added to the parser, so you can
write expressions like "if(a) b();" just like in C. Note that there's
still a parser bug in there that fails when you nest a braced block
within a braceless one.
Character constants that appear in Nasal source code can now be
literal multibyte UTF8 characters (this was always supported for
string literals, but character constants were forced to be a single
byte).
New modules: "bits", "thread", "utf8" and (gulp...) "io". The bits
library might be useful to FlightGear, the utf8 one probably not as
Plib does not support wide character text rendering. The thread
library will work fine for spawning threads to do Nasal stuff, but
obviously contact with the rest of FlightGear must be
hand-synchronized as FlightGear isn't threadsafe. The io library is
no doubt the most useful, as it exposes all the basic stdio.h
facilities; it's also frighteningly dangerous when combined with
networked code...
have no children (in which case they default to 1px thickness & stretch).
This allows to just write <hrule/> instead of <hrule><dummy/></hrule>.
One can still use <hrule><pref-height>3</pref-height></hrule>, of course.
layout.cxx: drop silly do??Box calls for hrule/vrule (yes, I wrote that :-)
discard the display part. The curly braces wouldn't be spoken anyway,
and the | would be spoken as "vertical bar", which is completely
useless (which is why it had been disabled in the past already).
- drop the DEFAULT keyword in .fg-submit configuration files. That was
a silly idea. The default rules are now always appended. One can still
bypass them by ALLOWing or DENYing anything before, for example, by using
DENY *, or ALLOW *.
- fix a typo that broke ~/.fg-submitrc loading (but ~/.fg-submit worked anyway)
- some minor improvments, cleanup and all that
- fix config file name in $HOME; This didn't match the documentation.
(doesn't cost us anything to check ~/.fg-submit first, and then ~/.fg-submitrc)
- don't use mktemp for the backup files. Some outdated distributions
(Debian) come with a version that mandates six X, which is just too ugly.
Just find the first free slot with sequential number. That isn't thread
safe, but mktemp isn't either, so ... (Should be using "lockfile", but
its availability on CygWin is questionable. And it's not *that* important.)
- some more documentation
- some cleanup, too, of course
ALLOW, DENY, IGNORE, DEFAULT ... see documentation on top
- make fg-upload arguments like the documentation says. (I had accidentally
left $1=$PWD, $2=archive, $3=diff, while it should be $1=archive, $2=diff)
- add -v option (verbose)
fg-submit:
- takes alternative optional basename (used instead of dirname)
- calls optional user defined fg-upload script at the end (example on top)
- minor fixes, different color for changed binary files
- cleanup, improved documentation
submitting. Detects various kinds of ugliness, but also reports false
positives. (People aren't supposed to compress texture filer so save
40 bytes. ;-)
- bugfix in fg-submit + some more cleanup and cosmetics
"Implement 'flightplans' for AIShips. This patch also introduces the concept
of a 'WAIT' token for AIShips: when the flightplan reaches a 'WAIT', the
AIShip stops and pauses for the specified time (secs)."

Fix Y2K bug triggering string overflow
sim_control_.date_string is a char[7], so it can contain "yymmdd" and
