643656fcc3 Complain to user on save/resume.restore when it's disabled. 2023-03-04 19:48:17 -05:00
Rob Swindell (on Debian Linux)
dfff80faa8 Add optional auto-save/restore feature using -a <filename> option 
To enable use with online Bulletin Board Systems (BBSes) where users
may be disconnected unexpectedly, but would naturally want to resume
playing their same game, added support for an optional save game
path/filename to be specified on the command-line (very similar to
"-r <filename>"), except this save/restore file is:
1. automatically loaded/restored if it exists
2. automatically created when starting a new game
3. automatically updated when exiting a game for any reason
4. cannot be changed to a different path/filename by the user

Since a BBS server program can be expected to send a SIGHUP or SIGTERM
to the game process upon user disconnection (or timeout), those
signals are caught and a graceful termination will occur which saves
the current game state.

Build with ADVENT_AUTOSAVE defined to enable this option.

BUG:
The 'info' command still reports the save/suspend/pause commands as
valid, though they are not when this build option is used (same is
true of ADVENT_NOSAVE, and that doesn't apparently bother anyone).

81af59974b The FORTRAN-derived longs were semantically ints. Make it so. 
Note. because we used fixed-length declrations in the right places, this
shouldn't break saves.

(Besides being right, this will someday make a port to Go a touch easier,
if we decide to do that.)

076bb8908b If divident negative, then remainder is negative too. 
RNG values need to be always positive.
Solution: Transposing positively by divisor. In all the two places it may happen.

Also make the 'savetime' value meaningful.

This removes a separate library dependency on some systems.

58b44313d3 Without IGNORE, -Wunused-result throws a warning on fread(2). 
I've seen it happen on fwrite(2) as well; wrapping that as well in
case some compiler decides to be finicky.

8bc08773fa Various cleanups. 
* Remove disused macro.
* GCC doesn't seem to mind if IGNORE() is left off.
* Enumify phase codes.
* Use EXIT_* macros in all exit() calls.
* How did this even work without extern?
* Give advent.h a much-needed makeover.
* Use the chomp indicator in YAML string blocks to avoid code ugliness.

50435465a6 Completely wire vocab words in YAML to the code. 
This massive patch:
* Finishes working all the vocab words into YAML structures.
* Adds vocab ID generator functions.
* Redoes the input-getting system, removing the need for GETIN(),
  GETTXT(), etc.
* Changes advent<->ascii mapping to avoid the special 'shift'
  character.
* Works around some bad behavior in the dragon attack logic.
* Handles the reservoir magic word without changing the database
  contents.

59243cf8bc Take FORTRANish upper-case function names to C-style lowercase... 
...except for a few we're planning to get rid of.  This will avoid some
upcoming collisions with macros defined from YAML.
