Bill Currie	35f12c36ff	[util] Catch some more cexpr errors	2021-02-09 19:29:48 +09:00
Bill Currie	16334158bd	[util] Support struct pointer accesses in cexpr	2021-01-10 01:51:07 +09:00
Bill Currie	a45f8f98b6	[util] Make exprctx hashlinks double pointer ... The way I wound up using the field meant that exprctx should not "own" the hashlinks chain, but rather just point to it. This fixes the nasty access errors I had.	2021-01-05 19:55:17 +09:00
Bill Currie	79f22ffebf	[util] Propagate cexpr errors back to the caller ... Not much point in error detection when it's ignored.	2020-12-21 20:15:43 +09:00
Bill Currie	f3682638d4	[util] Add a mini expression parser ... It is capable of parsing single expressions with fairly simple operations. It current supports ints, enums, cvars and (external) data structs. It is also thread-safe (in theory, needs proper testing) and the memory it uses can be mass-freed.	2020-12-21 14:22:42 +09:00
