This updates `fmt` to the latest version and moves to just being a copy
of their repo to make updating easier (no editing their cmake / figuring
out which files to minimally include).
The motivation for this is now that we switched to C++ 20, there were a
ton of deprecated function usages that is going away in future compiler
versions. This gets rid of all those warnings.
Started at 349,880,038 allocations and 42s
- Switched to making `Symbol` in GOOS be a "fixed type", just a wrapper
around a `const char*` pointing to the string in the symbol table. This
is a step toward making a lot of things better, but by itself not a huge
improvement. Some things may be worse due to more temp `std::string`
allocations, but one day all these can be removed. On linux it saved
allocations (347,685,429), and saved a second or two (41 s).
- cache `#t` and `#f` in interpreter, better lookup for special
forms/builtins (hashtable of pointers instead of strings, vector for the
small special form list). Dropped time to 38s.
- special-case in quasiquote when splicing is the last thing in a list.
Allocation dropped to 340,603,082
- custom hash table for environment lookups (lexical vars). Dropped to
36s and 314,637,194
- less allocation in `read_list` 311,613,616. Time about the same.
- `let` and `let*` in Interpreter.cpp 191,988,083, time down to 28s.
Normally, when they allocate a VagCmd, they do a bunch of stuff to clear
all the status bits and reset things
in particular the InitVAGCmd function does a lot

but for the stereo command, they do a lot less:

Which means that the new_stereo_command can just have random status bits
left over from whatever the last user had.
we seem to end up in a state where byte21 is set, and this causes
everything else to be wrong and off-by-one dma transfer. My guess is
that the original game avoided this bug due to lucky timing that I don't
understand.
I think the fix of just clearing byte21 is ok because there's no way
that the old value of the byte is useful after the command is
repurposed.
This automatically generates documentation from goal_src docstrings,
think doxygen/java-docs/rust docs/etc. It mostly supports everything
already, but here are the following things that aren't yet complete:
- file descriptions
- high-level documentation to go along with this (think pure markdown
docs describing overall systems that would be co-located in goal_src for
organizational purposes)
- enums
- states
- std-lib functions (all have empty strings right now for docs anyway)
The job of the new `gen-docs` function is solely to generate a bunch of
JSON data which should give you everything you need to generate some
decent documentation (outputting markdown/html/pdf/etc). It is not it's
responsibility to do that nice formatting -- this is by design to
intentionally delegate that responsibility elsewhere. Side-note, this is
about 12-15MB of minified json for jak 2 so far :)
In our normal "goal_src has changed" action -- we will generate this
data, and the website can download it -- use the information to generate
the documentation at build time -- and it will be included in the site.
Likewise, if we wanted to include docs along with releases for offline
viewing, we could do so in a similar fashion (just write a formatting
script to generate said documentation).
Lastly this work somewhat paves the way for doing more interesting
things in the LSP like:
- whats the docstring for this symbol?
- autocompleting function arguments
- type checking function arguments
- where is this symbol defined?
- etc
