There is a lot of code affected by this, and Pat Rankin correctly
observes that it would be better to store roguelike as a level flag
rather than just using Is_rogue_level. A note for the future.
In the newsgroup about three weeks ago someone described trying to
use the Bell of Opening to find the magic portal on the Plane of Water
and not succeeding. It's supposed to work like a wand of secret door
detection to mark nearby traps as known. And does, but it turns out
that the wand wasn't working as expected there either. They both require
line of sight, and since the water outside of the bubbles blocks that
they only found the portal if it was within the same bubble as the hero.
(Clouds on the Plane of Air posed a similar problem, although monster
activity usually reveals the portal on that level so this wasn't much of
an issue there.) Since the detection magic doesn't require the hero to
see the traps--wand and Bell both work while blind--this patch overrides
the line of sight requirement on the Planes of Water and Air. As long as
hero is within the detection magic's range, the portals on those levels
will get marked as having been seen and when the hero gets into the right
bubble or out of the clouds the portal traps will be shown on the map.
The line-of-sight override code is simple-minded and lets players
find traps through boulders when/if those are present (but the found
traps won't be seen yet since vision still controls the map display).
Also, it assumes that only water/air/cloud terrain is present so could
potentially yield strange results if any other terrain gets introduced on
either of those two levels.
Add Hojita Discordia's Dungeon Map overview as
conditional code for experimentation and testing.

Dungeon Map Overview Patch for Nethack 3.4.3
Version 3
=============================================================================
Changelist:
v3: Changed #level to #annotate to avoid #levelchange collision. Fixed
handling of elemental planes and astral plane (oops). Changed
formatting to be slightly closer to print_dungeon()'s. Should be
"final" version for 3.4.3.
v2: Added tracking of trees. Changed ctrl-m command to ctrl-o. Portals
displayed as "sealed" instead of "closed".
v1: First release.
(Note: all versions are mutually save compatible.)
=============================================================================
This patch creates a dungeon map overview that is recorded as the player
explores the dungeon. I was tired of returning to a game a few days later
and having no idea what the dungeon looked like. Trying to name pieces
of armor with shorthand didn't work so well as an intermediate solution
either, especially around nymphs.
It can be assumed that this map is in the mind of the hero and thus
can't be stolen, can be read when blind, or when buried, or when the hero
doesn't have any hands, or eyes, or hands free, or...etc. On the other hand,
this implies that the hero doesn't remember all of the details ("a fountain",
"some fountains", "many fountains") and that the map is subject to amnesia
when applicable.
This overview tracks fountains, altars, stores, temples, sinks, thrones,
trees, and dungeon branches. It attempts to not spoil the player nor
reveal more information than the hero knows. For this reason, it only
tracks dungeon features found in the guidebook and dungeon branches.
This patch breaks save file compatibility. Sorry.
Added commands
=============================================================================
#overview (ctrl-o, if not in wizard mode) - displays overview
#annotate (ctrl-n, if using numpad) - names current level
Example Output From #overview
=============================================================================
The Dungeons of Doom: levels 1 to level 15
Level 1:
A fountain
Level 3: (My stash.)
An altar, some fountains
Stairs down to The Gnomish Mines
Level 7:
Many fountains
Level 8:
Stairs up to Sokoban, level 7
Level 15:
A general store
Sealed portal to The Quest
The Gnomish Mines: levels 4 to level 7
Level 7: <- You are here
Many stores, some fountains, a temple
More Details
=============================================================================
The overview shows only levels that have anything interesting to display and
doesn't show branches that don't have any interesting levels.
To avoid the map revealing more information than the hero knows, the overview
only displays things that the hero has seen or touched. (If the hero
blinds herself, levitates above a known fountain, and obliterates it with a
wand of digging, the overview will still say that there is a fountain.)
This is done, sadly, by adding 6 bits to the rm struct to track the last
known dungeon type. On the other hand, this change could potentially allow
a window port to do something like drawing an item and a fountain on the same
square.
Things That Could Be Better And Maybe Some Feedback Would Help
=============================================================================
"<- You Are Here" is pretty goofy
-...but an indicator of some sort is nice.
=============================================================================
Many thanks to all the kind folks on r.g.r.n. who had very good feedback
about this patch, in particular L (for the trees), <Someone> Papaganou (for the
#annotate suggestion and some formatting feedback), and <Someone> (for the suggestion
of just overriding ctrl-o instead of using the very broken ctrl-m.)
=============================================================================
20060311. Hojita Discordia. (My usenet email is bogus. Sorry.)
From a bug report: zapping force
bolt broke an adjacent potion of blindness (possibly carried by the monster
he was attacking) which caused "it suddently gets dark" but further course
of the bolt resulted in now blinded hero recieving "a door appears in the
wall". make_blinded() was deferring vision recalculation until next pass
through moveloop() (or until next pline()--if the "gets dark" message had
been delivered after the call to make_blinded() instead of before, this
wouldn't have been noticeable). Fix is trivial: just recalculate vision
immediately when temporary blindness is toggled. [It might also be needed
for involuntary blindfold removal, although I suspect that that is always
accompanied by corresponding pline() which gets vision back into synch.]
If you dug in a pit next to a sleeping, angry monster, you'd stop every
turn due to a complex check at the end of dochugw. It turned out this
was due to a long-standing bug in the special case vision code that failed
to set the COULD_SEE bit for the locations where it set the IN_SIGHT bit.
It looks like the underwater code had the same problem (it didn't set the
bit, obviously there are no pits underwater). However, the same could
occur if you see the angry, sleeping monster with Xray vision. In this
case, setting COULD_SEE is not appropriate, so added a mcanmove check to
the complex check in dochugw.
- new iflags.vision_inited to determine if vision is ready to go.
- the flag is set the first time vision_reset() completes, actually every time
- vision_recalc() checks the flag before doing anything.
