sst.py =-- Super Star Trek in Python

This code is a Python translation of a C translation of a FORTRAN original.
The FORTRANness still shows in many ways, notably the use of a lot of
parallel arrays where a more modern language would use structures
or objects.  (However, 1-origin array indexing was fixed.)

Dave Matuszek says:

SRSCAN, MOVE, PHASERS, CALL, STATUS, IMPULSE, PHOTONS, ABANDON,
LRSCAN, WARP, SHIELDS, DESTRUCT, CHART, REST, DOCK, QUIT, and DAMAGE
were in the original non-"super" version of UT FORTRAN Star Trek.

Tholians were not in the original. Dave is dubious about their merits.
(They are now controlled by OPTION_THOLIAN and turned off if the game
type is "plain".)

Planets and dilithium crystals were not in the original.  Dave is OK
with this idea. (It's now controlled by OPTION_PLANETS and turned 
off if the game type is "plain".)

Dave says the bit about the Galileo getting turned into a
McDonald's is "consistant with our original vision".  (This has been
left permanently enabled, as it can only happen if OPTION_PLANETS
is on.)

Dave also says the Space Thingy should not be preserved across saved
games, so you can't prove to others that you've seen it.  He says it
shouldn't fire back, either.  It should do nothing except scream and
disappear when hit by photon torpedos.  It's OK that it may move
when attacked, but it didn't in the original.  (Whether the Thingy
can fire back is now controlled by OPTION_THINGY and turned off if the
game type is "plain" or "almy".  The no-save behavior has been restored.)

The Faerie Queen, black holes, and time warping were in the original.

Here are Tom Almy's changes:

In early 1997, I got the bright idea to look for references to
"Super Star Trek" on the World Wide Web. There weren't many hits,
but there was one that came up with 1979 Fortran sources! This
version had a few additional features that mine didn't have,
however mine had some feature it didn't have. So I merged its
features that I liked. I also took a peek at the DECUS version (a
port, less sources, to the PDP-10), and some other variations.

1, Compared to the original UT version, I've changed the "help" command to
"call" and the "terminate" command to "quit" to better match
user expectations. The DECUS version apparently made those changes
as well as changing "freeze" to "save". However I like "freeze".
(Both "freeze" and "save" work in SST2K.)

2. The experimental deathray originally had only a 5% chance of
success, but could be used repeatedly. I guess after a couple
years of use, it was less "experimental" because the 1979
version had a 70% success rate. However it was prone to breaking
after use. I upgraded the deathray, but kept the original set of
failure modes (great humor!).  (Now controlled by OPTION_DEATHRAY
and turned off if game type is "plain".)

3. The 1979 version also mentions srscan and lrscan working when
docked (using the starbase's scanners), so I made some changes here
to do this (and indicating that fact to the player), and then realized
the base would have a subspace radio as well -- doing a Chart when docked
updates the star chart, and all radio reports will be heard. The Dock
command will also give a report if a base is under attack.

4. Tholian Web from the 1979 version.  (Now controlled by
OPTION_THOLIAN and turned off if game type is "plain".)

5. Enemies can ram the Enterprise. (Now controlled by OPTION_RAMMING
and turned off if game type is "plain".)

6. Regular Klingons and Romulans can move in Expert and Emeritus games. 
This code could use improvement. (Now controlled by OPTION_MVBADDY
and turned off if game type is "plain".)

7. The deep-space probe feature from the DECUS version.  (Now controlled
by OPTION_PROBE and turned off if game type is "plain").

8. 'emexit' command from the 1979 version.

9. Bugfix: Klingon commander movements are no longer reported if long-range 
sensors are damaged.

10. Bugfix: Better base positioning at startup (more spread out).
That made sense to add because most people abort games with 
bad base placement.

In June 2002, I fixed two known bugs and a documentation typo.
In June 2004 I fixed a number of bugs involving: 1) parsing invalid
numbers, 2) manual phasers when SR scan is damaged and commander is
present, 3) time warping into the future, 4) hang when moving
klingons in crowded quadrants.  (These fixes are in SST2K.)

Here are Stas Sergeev's changes:

1. The Space Thingy can be shoved, if you ram it, and can fire back if 
fired upon. (Now controlled by OPTION_THINGY and turned off if game 
type is "plain" or "almy".)

2. When you are docked, base covers you with an almost invincible shield. 
(A commander can still ram you, or a Romulan can destroy the base,
or a SCom can even succeed with direct attack IIRC, but this rarely 
happens.)  (Now controlled by OPTION_BASE and turned off if game 
type is "plain" or "almy".)

3. Ramming a black hole is no longer instant death.  There is a
chance you might get timewarped instead. (Now controlled by 
OPTION_BLKHOLE and turned off if game type is "plain" or "almy".)

4. The Tholian can be hit with phasers.

5. SCom can't escape from you if no more enemies remain 
(without this, chasing SCom can take an eternity).

6. Probe target you enter is now the destination quadrant. Before I don't 
remember what it was, but it was something I had difficulty using.

7. Secret password is now autogenerated.

8. "Plaque" is adjusted for A4 paper :-)

9. Phasers now tells you how much energy needed, but only if the computer 
is alive.

10. Planets are auto-scanned when you enter the quadrant.

11. Mining or using crystals in presense of enemy now yields an attack.
There are other minor adjustments to what yields an attack
and what does not.

12. "freeze" command reverts to "save", most people will understand this
better anyway. (SST2K recognizes both.)

13. Screen-oriented interface, with sensor scans always up.  (SST2K
supports both screen-oriented and TTY modes.)

Eric Raymond's changes:

Mainly, I translated this C code out of FORTRAN into C -- created #defines
for a lot of magic numbers and refactored the heck out of it.

1. "sos" and "call" becomes "mayday", "freeze" and "save" are both good.

2. Status report now indicates when dilithium crystals are on board.

3. Per Dave Matuszek's remarks, Thingy state is never saved across games.

4. Added game option selection so you can play a close (but not bug-for-
bug identical) approximation of older versions.

5. Half the quadrants now have inhabited planets, from which one 
cannot mine dilithium (there will still be the same additional number
of dilithium-bearing planets).  Torpedoing an inhabited world is *bad*.
There is BSD-Trek-like logic for Klingons to attack and enslave 
inhabited worlds, producing more ships (only is skill is 'good' or 
better). (Controlled by OPTION_WORLDS and turned off if game 
type is "plain" or "almy".)

6. User input is now logged so we can do regression testing.

7. More BSD-Trek features: You can now lose if your entire crew
dies in battle.  When abandoning ship in a game with inhabited
worlds enabled, they must have one in the quadrant to beam down
to; otherwise they die in space and this counts heavily against
your score.  Docking at a starbase replenishes your crew.

8. Still more BSD-Trek: we now have a weighted damage table.
Also, the nav subsystem (enabling automatic course
setting) can be damaged separately from the main computer (which
handles weapons targeting, ETA calculation, and self-destruct).

After these features were added, I translated this into Python and added
more:

9. A long-range scan is done silently whenever you call CHART; thus
the LRSCAN command is no longer needed.  (Controlled by OPTION_AUTOSCAN
and turned off if game type is "plain" or "almy".)

    # devices (such as the computer, which is in the core of the
    # ship and has considerable redundancy) almost never get
    # damaged, whereas devices which are exposed (such as the
    # warp engines) or which are particularly delicate (such as
    # the transporter) have a much higher probability of being
    # damaged."
