* Rewrite and redesign codegen and feature systemGravatar Michael Smith 2025-04-062-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Rework OS abstractionsGravatar Michael Smith 2024-08-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | - As much as possible avoid dragging system headers into translation units. This should avoid namespace pollution and, hopefully, speed up builds a little bit. - Avoid leaning on the UCRT so much on Windows - prefer native win32 calls and native file handles except where doing so is inconvenient (in particular, for stat(), which we might try and replace later). - Also, switch from SystemFunction036 to ProcessPrng on Windows. This requires us to generate a stub for bcryptprimitives.dll because Microsoft haven't bothered to provide a link library, but the function is better-documented and seems to be a more direct under-the-hood call as well. Apparently it's what's used by the major web browsers these days, which seems like a good indication it's stable and trusted. - Lastly, remove a bunch of functions and macros and stuff that weren't actually being used. It seems good to try and keep the scope of OS-dependent stuff relatively contained and only add to it when actually required.
* Tweak feature sorting and fix a chibicc bugGravatar Michael Smith 2023-06-201-23/+5
| | | | | | | | | 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.
* Move towards C23, improve events and vcall macrosGravatar Michael Smith 2022-09-132-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
