7bf56ac60e Simplify build: nested makefiles considered harmful. 2017-06-13 20:43:42 +03:00

0b02f361de Move database compilation out into its own tool (for now). 2017-06-13 20:43:42 +03:00

372fc1fbef Apply further polish and add in a couple of missing size variables. 2017-06-13 20:43:41 +03:00

e281f895d4 Factor out handling of variables populated from the database. 
This reorganization is a first step toward handling database compilation separately.

6fb8265577 Ensure the ZZZZ magic word is reproducible. 
This happens by making the SEED command also regenerate the magic word.

ff467f276b Implement fallback handler that looks at the raw command buffer. 
With database cinpilation not broken this time...

341bf61139 Once again, take srand()/random() out of the initialization chain. 
They have exactly the wrong kind of randomness for this job - not
returning consistent sequences across different platforms or C library
versions, and because pseodorandom not really better than sampling
the clock.

06795f691f Revert SEED handling and comment orocessing. It broke database compilation. 
This code is remarkably like the game it implements - a maze of twisty
little FORTRANisms, all alike.  Very easy to get lost.

016bcf2ff2 Seed command fully implemented but apparently buggy. 
Dwarf appearance is not yet reproducible.

aa7e291bc6 Revert structurization changes, they broke database compilation... 
...bug showing only if adventure.data was absent.  We'll need to sneak up
on this more carefully.

3f57114791 Revert a variable name previously changed to be out of the way. 
Also, make output from replays easier to interpret by adding prompts.

91bfd55c1c Begin gathering saveable game state into a structure. Not yet complete. 
No logic changes.  A bunch of globals turn into fields (with the same names
except for lowercasing) in struct game_t.

Eventually this will allow drastic simplification of the save/load logic.

ec4c0c8cd0 Input source is parametrized all the way down. 
This means that, potentially, do_command() could be called on any text file
pointer and the right thing would happen.

42e6e7cdb7 Fix strange inside-out organization of the input routines. 
Seems to have nbben a result of FORTRAN not having anything like a
stream object that can be passed around.

A step towards logging and log replay.

301f38586b Fix up case on all comments to make them more readable. No code changes. 
The all-capsing was a FORTRAN remnant.Also, we change a few FORTRANisms
so they are less confusing in this C context; ".TRUE." and ".FALSE." become
"true" and "false", "MOD" is mapped to % in places tha t are like C expressions
and (usually) "modulo" in places that aren't.

Constants and formals have been converted, but not globals yet.

6ef3e68c0c Replace fDATIME with ANSI/POSIX clock_gettime(). Rip out DOS/AMIGA shims. 
The thinking here is that we simplify life by going pure ANSI/POSIX.
This is a text game.  If it ever runs on anything but Unix again it's
almost certain to be on something like WSL that supplies a
POSIX-conformant text console.
