This was making vgui stuff fail in L4D2 because the other outer conditions would match first. It's perhaps unfortunate that we have to remove short-circuiting in cases where it would work fine, but who knows, maybe the compiler would be smart enough to figure it out anyway. At any rate it's necessary for correctness, so whatever. 2025-10-11T02:13:18+00:00 Michael Smith mikesmiffy128@gmail.com 2025-10-11T02:09:35+00:00 urn:sha1:74f1309af5310fbfa346048f8ecfc7fe1e8a4571 The old GAMESPECIFIC mechanism had worked in practice but was technically a little bit incorrect, oops. 2025-10-11T00:36:16+00:00 Michael Smith mikesmiffy128@gmail.com 2025-10-11T00:35:54+00:00 urn:sha1:b447f5879d0c4c49d72f167ed2cf0f1e44a52123 The NE thing wasn't really correct, because it would match hypothetical cases where OE and some other tag bit are both set. Now we simply use !OE instead. The _GAMES_WITH inversion case is correct, because it doesn't necessarily exclude OE from being included too. 2025-06-27T21:52:10+00:00 Michael Smith mikesmiffy128@gmail.com 2025-06-27T21:45:11+00:00 urn:sha1:36910c88033bcc4b25df5c64ed066c633dc4eac2 This took longer to debug than one might like to admit. In some very specific cases, the loop condition would fail before the return condition, causing the rest of the logic to proceed with out-of-bounds accesses to indents and exprs (which are zero-initialised), in turn leading to garbage getting dumped into the generated header. The garbage in question would be line 0, and [argv[0] 2025-04-30T21:55:05+00:00 Michael Smith mikesmiffy128@gmail.com 2025-04-30T21:55:05+00:00 urn:sha1:7b7cb45f7c1ed307b585ab3506dc57854ec076a6 Specifically when building in debug mode, we now: * Display all features on load, including skipped and internal ones, sorted by internal name instead of display name. * Print the names of all matched gametype tags after the feature list. * Add an sst_dbg_getcmdcb command to get the address of a command callback for quick breakpoint insertion or Ghidra lookup. * Add an sst_dbg_sendtables command to dump out the full ServerClass tree to help get names for entprops.txt. Note: this output is very long so you'll likely need to log console output to a file to be able to read it all. There's a bunch of developer experience and debug help stuff I want to get done eventually. This is just a very small piece, but it's a start. 2025-04-08T00:35:13+00:00 Michael Smith mikesmiffy128@gmail.com 2025-04-08T00:32:41+00:00 urn:sha1:6c8cd62277a9c81d1d24c146067c405ec90cbfb2 2025-04-07T20:31:32+00:00 Michael Smith mikesmiffy128@gmail.com 2025-04-07T20:31:32+00:00 urn:sha1:58b495650f7613cdebfe78fff9de2b99556f1998 They're legally unnecessary as far as I know, and kind of annoying to maintain on a long-term basis. This was done with the consent of all 3 other contributors, in case anyone was wondering. 2025-04-06T15:41:13+00:00 Michael Smith mikesmiffy128@gmail.com 2025-03-10T20:37:28+00:00 urn:sha1:daa55cade14146f04814cf8a7ad2028becf4db66 In the future we can also consider moving to {} instead of {0} for initialisers, but my old Clang (16) doesn't support this, so it might be wise to wait longer on that one so people don't need too bleeding-edge of a compiler just to build this thing. 2025-04-06T15:41:13+00:00 Michael Smith mikesmiffy128@gmail.com 2025-03-10T02:37:19+00:00 urn:sha1:244fea664121acf12871ab5858a5fe95a2606b52 Also switch to somewhat proper C23 flags while we're at it. This is a huge change. It took me forever, in between being really busy. Sorry about that. But the good news is I'm now free to start integrating the various patches that have accumulated since last release. Well, at least in between still being really busy. Gotta manage expectations. The main benefit of introducing GAMESPECIFIC() is that features that don't apply to a particular game no longer show up *at all*, and less time is wasted on init. It also enables a cool optimisation wherein unnecessary REQUIRE_GAMEDATA() checks can elided at compile time whenever the gamedata is known up-front to always exist in supported games. The DEF_FEAT_CVAR macro family meanwhile makes it easier to manage the lifecycle of cvars/ccmds, with less manual registering, unhiding and such. Originally I was going to try and just hack these features into the existing codegen abomination, but it just got too terrible. This rewrite should make it easier to continue tweaking codegen behaviour in future. It also has slightly better error messages. 2024-08-23T19:40:01+00:00 Michael Smith mikesmiffy128@gmail.com 2024-08-21T23:02:48+00:00 urn:sha1:cf0354eb8e043fcd9c6c17756701972f948a16f1 This removes the horrible janky old KeyValues parser and replaces it with a couple of trivial ad-hoc text parsers. In doing so, make the format of the actual gamedata files more human-friendly too. We also gain support for nested SendTables in mkentprops, which are required to get at various things like player velocity. And, the actual string matching is made more efficient (or, at least, more scalable) by way of a cool radix tree thing which generates a bunch of switch cases on distinct characters.
