This essentially re-does the work of #875 on top of master.
This is what I did to check that Cosmo's Lua extensions still worked:
```
$ build/bootstrap/make MODE=aarch64 o/aarch64/third_party/lua/lua
$ ape o/aarch64/third_party/lua/lua
>: 10
10
>: 010
8
>: 0b10
2
>: string.byte("\e")
27
>: "Hello, %s" % {"world"}
Hello, world
>: "*" * 3
***
```
`luaL_traceback2` was used to show the stack trace with parameter
values; it's used in `LuaCallWithTrace`, which is used in Redbean to run
Lua code. You should be able to see the extended stack trace by running
something like this: `redbean -e "function a(b)c()end a(2)"` (with
"params" indicating the extended stack trace):
```
stack traceback:
[string "function a(b)c()end a(2)"]:1: in function 'a', params: b = 2;
[string "function a(b)c()end a(2)"]:1: in main chunk
```
@pkulchenko confirmed that I get the expected result with the updated
code.
This is what I did to check that Lua itself still worked:
```
$ cd third_party/lua/test/
$ ape ../../../o/aarch64/third_party/lua/lua all.lua
```
There's one test failure, in `files.lua`:
```
***** FILE 'files.lua'*****
testing i/o
../../../o/aarch64/third_party/lua/lua: files.lua:84: assertion failed!
stack traceback:
[C]: in function 'assert'
files.lua:84: in main chunk
(...tail calls...)
all.lua:195: in main chunk
[C]: in ?
.>>> closing state <<<
```
That isn't a result of these changes; the same test is failing in
master.
The failure is here:
```lua
if not _port then -- invalid seek
local status, msg, code = io.stdin:seek("set", 1000)
assert(not status and type(msg) == "string" and type(code) == "number")
end
```
The test expects a seek to offset 1,000 on stdin to fail — but it
doesn't. `status` ends up being the new offset rather than `nil`.
If I comment out that one test, the remaining tests succeed.
- Expand redbean UNIX module
- Expand redbean documentation
- Ensure Lua copyright is embedded in binary
- Increase the PATH_MAX limit especially on NT
- Use column major sorting for linenoise completions
- Fix some suboptimalities in redbean's new UNIX API
- Figured out right flags for Multics newline in raw mode
Redbean Lua Server Pages may now be stored in the zip as byte code. This
can improve performance, since redbean currently doesn't cache byte code
but it might be more useful for anyone wanting to create a closed source
redbean. The .lua extension should be used for byte code files. Lua will
tell them apart based on a magic number at the start of the file.
This change also improves some Lua error reporting conditions. See #97
