2022-04-26Fix a couple of bits of convar min/max brokennessMichael Smith
It's amazing how long these things can go unnoticed.
2022-04-24Replace udis86 with a very small x86 decoderMichael Smith
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.
2022-03-20Support deferring cvar registrationMichael Smith
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.
2022-03-19Spruce up text and fix some copyright yearsMichael Smith
Sometimes, you just want to Unicode.
2022-01-18Very slightly tidy RTTI stuffMichael Smith
More handwavey Linux prep, nothing too significant.
2022-01-06Tidy up stubs, make vstdlib a stub, build on LinuxMichael Smith
Important note: it doesn't WORK on Linux, and there's tons of warnings and stuff, but it's easier to work on when all the compiler output and whatnot is there.
2021-12-29Make convar init macro type-genericMichael Smith
This removes the need to call atof() on each cvar on plugin load; now all that's required is the memory allocations for the string values. The syntax is also a bit nicer since numbers can just be numbers rather than quoted strings. Minor issue: specifying a string value that also happens to be numeric will break this since the numeric representation will be zero, but I can't see a reason this would ever happen. Also, add a DEF_CVAR_MAX just for completeness.
2021-12-26Unhide useful commands and allow cheats in lobbiesMichael Smith
This is done through a new "fixes" file which will probably become one of those silly dumping grounds that every project has to have somewhere to put random miscellaneous crap in. These are mainly hidden in L4D2 but they just get unilaterally unhidden if they exist, just to be sure they're accessible. As a bonus, it turns out that unhiding a single cvar also allows us to set sv_cheats 1 in Left 4 Dead 2, bringing an end to the need to port- forward a listen server for co-op practice.

With code from Bill. Thanks Bill!
