* Rewrite and redesign codegen and feature systemGravatar Michael Smith 2025-04-061-537/+0
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Revise syntax macros and add a ton of branch hintsGravatar Michael Smith 2024-08-231-4/+5
| | | | | | | | | My new programming style is branch hints. All non-confusing branches must be hinted when I can be bothered. It's faster, sometimes, maybe. Also, start trying to use more signed sizes in at least some of the places where it makes sense. Unsigned sizes are surprisingly error-prone!
* Get things at least compiling under LinuxGravatar Michael Smith 2023-08-271-2/+3
| | | | | | | | | | | Nothing really works yet, but at least test.h and fastspin are fixed and some of the issues with RTTI and libdl and stuff are maybe kind of sorted, subject to more testing later. The main issue now seems to be the cvar interface not quite lining up and crashing pretty much immediately. That'll probably take a lot more debugging to figure out, which likely still won't be a priority for quite a while.
* Make various preparations for upcoming featuresGravatar Michael Smith 2023-08-021-1/+12
| | | | | | | | | | | | | | | | | | | | | | A lot of this is random WIP from a while back, at least a month ago, and is being committed now to get it out of the way so that other patches can be brought in and integrated against it without causing headaches. Also rolled into this commit is a way to distinguish plugin_unload from exiting the game. This is required for another soon-to-be-integrated feature to avoid crashing on exit, and could in theory also be used to speed up unloading on exit in future. While we're at it, this also avoids the need to linearly scan through the plugin list to do the old branch unloading fix, because we can. Rough summary of the other smaller stuff I can remember doing: - Rework bitbuf a bit - Add some cryptographic nonsense in ac.c (not final at all) - Introduce the first couple of "chunklets" libraries as a sort-of subproject of this one - Tidy up random small bits and bobs - Add source for a small keypair generation tool - Rework democustom to be very marginally more useful
* Tweak feature sorting and fix a chibicc bugGravatar Michael Smith 2023-06-201-6/+6
| | | | | | | | | That sorting function was a bit wonky, so make it just a little bit wonky instead. chibicc would produce confusing lex errors if given a stray single quote somewhere, so make it give non-confusing errors. Also get rid of canonicalize_newline() because it's unnecessary for SST so long as Windows Git isn't left in its default misconfigured state.
* Refactor the RGBA colour struct into engineapi.hGravatar Michael Smith 2023-05-041-10/+9
| | | | | | In both the engine and SST it's used in more places than just console printing, so it makes more sense to give it a more appropriate nanme and location.

* Move towards C23, improve events and vcall macrosGravatar Michael Smith 2022-09-131-14/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | Another big one. Here's a list of things: - Since the upcoming C23 standardises typeof(), use it as an extension for the time being in order to allow passing arbitrary types as macro/codegen parameters. It wouldn't have been a big leap to do this even without standardisation since it's apparently an easy extension to implement - and also, to be honest, this project is essentially glued to Clang anyway so who cares. - Likewise, bool, true and false are becoming pre-defined, so pre-pre-define them now in order to get the benefit of not having to remember one header everywhere. - Really ungodly/amazing vcall macro stuff now allows us to call C++ virtual functions like regular C functions. It's pretty cool! - Events can now take arbitrary parameters and come in two types: regular events and predicates. All this makes the base code even uglier but makes the feature implementation nicer. In other words, it places more of the cognitive burden on myself and less on other people who might want to contribute. This is a good tradeoff, because I'm a genius.

* Add entity property finding and L4D warp testingGravatar Michael Smith 2022-05-031-1/+1
| | | | | | | | This was a lot more code than expected, but it might be finally close to time to release the next beta... We'll see if any more rabbit holes present themselves to jump into, though.
* Replace udis86 with a very small x86 decoderGravatar Michael Smith 2022-04-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | hook_inline() uses the new x86_len() function to get instruction lengths instead of doing full-blown disassembly, which should be a tiny bit quicker, and also removes the next for about 90KiB of lookup tables and such in the final binary. The code-digging logic in demorecord is also rewritten to be opcode-based rather than mnenmonic based. In general, going forward the plan is to always rely on opcodes and thus avoid a bunch of disassembly work every plugin load. udis86 is still in the tree for now to provide dbg_asmdump(), but it's only compiled into debug builds and left out of releases completely. As such, the whole BSD licence statement is also gone from the distribution LICENCE files. There's now also a dbg_toghidra() which spits out a rebased address to look stuff up for proper reverse engineering, which might be more useful than dbg_asmdump() anyway. If nobody ends up using the latter ever again, udis86 could get chucked completely. We'll see. Also shoehorned into this commit are a couple more forgotten copyright year bumps and some general minor cleanup here and there, because I couldn't be bothered wading through all the diff hunks. Oh, and makebindist.bat now makes an effort to make the zip file timestamps predictable/reproducible. That should be a different commit for sure, but oh well too bad.
* Support deferring cvar registrationGravatar Michael Smith 2022-03-201-29/+28
| | | | | | | | This allows stuff to be registered conditionally. Unfortunately cmeta is now truly the worst thing of all time, but cleaning it up isn't a huge priority. On the plus side, codegen actually got simpler.
* Initial public snapshotGravatar Michael Smith 2021-11-201-0/+95
With code from Bill. Thanks Bill!
