snxtsct_area(). Callers march() and navi() clearly don't want it to
use conditionals. navi() used to zap them (just removed). march()
doesn't, which was a bug similar to #785447. It's less clear for
caller map(). I'd argue that conditionals apply to map's argument,
the unit number, not to the map itself. draw_map() zaps them anyway.
ability to switch off demand updates by setting update_wantmin to
zero. Setting update_demandpolicy to UDDEM_DISABLE does the job.
(update_policy_check): Fix lower bound for blitz_time.
provided the values all match:
(caseen): New.
(xundump): Initialize and finalize it.
(xundump2): Update it.
(deffld): Deal with repetition.
(fldval_must_match): New, considers repetition as well as NSC_CONST.
(setnum, setstr): Use it.
(subst.in): Substitute it. Fix prerequisites.
(read_builtin_tables): New.
(main): Call it. This doesn't do anything, because no builtin tables
have been defined.
(config_tables): New econfig key.
(read_config_tables): New, implements config_tables.
(main): Call it. Need to call ef_init() and chdir(configdir) first.
(ef_init_srv): Don't call ef_init(), since main() did it already.
Remove old way to do the same:
(ef_load): Remove, along with calls.
(empfile): Set configuration tables' member file back to NULL.
(ellipsis): New.
(xuheader1): Initialize it. Compute nflds. Allow repetition of index
field in continued tables.
(xundump): Don't set nflds.
(xufldname, defellipsis): Accept ... and call new defellipsis().
(xufldname, chkflds): Update and elaborate check for missing fields,
move it to new chkflds(). Require repetition of index field in
continued tables.
(xundump2): New, factored out of xundump(). Parse continued tables.
(xundump1, setnum, setstr, getobj, cur_id): Delay table lookup until
first field is about to be assigned.
(xundump1): Record largest ID, because it's no longer given by final
value of row.
(xuheader1, xundump1, xundump): Move initialization of cur_type to
xundump().
selectors. That's wrong for EF_SECTOR_CHR and EF_PRODUCT. Don't
allow table shrinking just because it has no NSC_CONST selectors.
That's wrong for EF_NEWS_CHR. Allow it for game state and unit
characteristics.
(has_const): Unused, remove.
still be in order), support abbreviated field names:
(nxt_sel, nxt_idx, nxtfld, ca4fld): Remove.
(nflds, fldca, fldidx, caflds, getfld): New.
(xundump): Initialize and finalize them.
(xundump1): New, factored out of xundump().
(deffld): Match names, record field order in fldca[], fldidx[] for
getfld(). Use caflds[] to detect duplicates.
(xufldname): Catch negative index. Used to pass it to deffld(), which
now interprets it as no index.
(setnum, setstr, setsym, mtsymset, add2symset): Use getfld().
(xufld): Improve error message.
(setstr): Fix for NULL strings.
(xuheader): Catch null ef_cadef().
(xuheader): Don't oops when an unexpected table can't be undumped.
leaks memory; rework it:
(deffld): New; semantic action for field headers.
(xufldname): Use it instead of storing a value for xucolumnheader().
(xucolumnheader): Remove, use xuflds() directly instead.
(setnum, setstr, setsym): New; semantic actions for field values.
(xufld): Use it instead of storing a value for xuloadrow().
(xuloadrow): Remove. Was incomplete.
(xufldname, xufld, xuflds): Remove parameter values. Callers
changed.
(cur_type, cur_obj, nxt_sel, nxt_idx, nxtfld, ca4fld, getsymtab): New
helpers.
(xundump): Initialize them.
(enum_value, value, freeflds, xunsymbol): Remove.
(mtsymset, add2symset): New.
(xufld): Use them to build a symbol set along the parse.
(xufldname, xufld, xuheader, xutrailer, xundump): Increment lineno
when and only when a linefeed is consumed, to make sure it is correct.
Move some semantic checks so that errors get reported for the correct
line.
(xundump): Use compare filenames as pointers, not strings, when
checking whether to reset lineno.
(xundump): Keep empfile[type] consistent during parse, to make
ef_ptr() usable.
(xundump): Don't call ep->init() on sentinels.
(xuinitrow): Unused, remove.
