Hoist `std::lerp()` into the global namespace instead.
|
|
GCC on Linux complains that "math.h", which hoists all the standard library
math functions into the global namespace for classic C compatibility, creates
a conflict between `std::lerp()` and the `lerp()` function in llmath.h.
(Perhaps we should just replace our `lerp()` definition with `using std::lerp;`)
Anyway, bringing in <cmath> rather than "math.h" leaves standard library math
functions in the `std` namespace, avoiding the conflict.

In C++20, `std::filesystem::u8path()` (that accepts a UTF-8 encoded
`std::string` and returns a `std::filesystem::path`) is deprecated. Instead,
to engage UTF-8 coding conversions, we're supposed to pass the `path`
constructor a `std::u8string`, i.e. a `std::basic_string<char8_t>`. Since
`char8_t` is a type distinct from both `char` and `unsigned char`, we must Do
Something to pass a UTF-8 encoded `std::string` into `std::filesystem::path`.
To avoid copying characters from a `std::string` into a temporary
`std::u8string` and from there into the `std::filesystem::path`, make a
`boost::transform_iterator` that accepts a `std::string_view::iterator` and
adapts it to dereference `char8_t` characters. Make `fsyspath(std::string_view)`
engage the base-class constructor accepting (iterator, iterator), adapting
`string_view::begin()` and `end()` to deliver `char8_t` characters.
Use the same tactic for `fsyspath::operator=(std::string_view)`, explicitly
calling `std::filesystem::path::assign()` with the adapted iterators.
To resolve ambiguities, provide both constructors and assignment operators
accepting `(const std::string&)` and `(const char*)`, explicitly converting
each to `std::string_view`.
At the same time, `std::filesystem::path::u8string()` now returns
`std::u8string` rather than `std::string`. Since `std::filesystem::path`
delivers only that `std::u8string` rather than iterators into its internal
representation, we can't avoid capturing it and copying to the returned
`std::string`.
Remove explicit `.u8string()` calls from a few existing `fsyspath` instances,
now that `fsyspath` supports implicit conversion to `std::string`.

Generalize LLPointer's comparison operators to allow comparable LLPointer types.
|
|
Given templated constructors and assignment operators, it's tempting to remove
specific constructors and assignment operators with the same LLPointer<Type>
parameters. That turns out to be a mistake. Add comments to warn future
maintainers.
|
|
This affords strong exception safety. Also, eliminating the conditional may
improve speed.
|
|
Instead of restating the whole class, requiring changes to be made in parallel
(which has already failed), just make a template alias.
|
|
That is, both `LLPointer::operator==()` and `operator!=()` and the free function
`operator==()` and `operator!=()` now accept pointer types other than the type
of the subject `LLPointer`, letting the compiler apply implicit pointer
conversions or diagnose an error.

Introduce `ScriptCommand` class that parses a command line into a script name
and optional args, using bash-like quoting and escaping. `ScriptCommand`
searches for a file with that script name on a passed list of directories; the
directories may be specified relative to a particular base directory.
`ScriptCommand` supports the special case of a script name containing unescaped
spaces. It guarantees that either the returned script file exists, or its
`error()` string is non-empty.
Replace `LLLeap::create()` logic, from which `ScriptCommand` was partly
derived, with a `ScriptCommand` instance.
Make `LLLUAmanager::runScriptFile()` use a `ScriptCommand` instance to parse
the passed command line.
Subsume `LLAppViewer::init()` script-path-searching logic for `--luafile`
into `ScriptCommand`. In fact that lambda now simply calls
`LLLUAmanager::runScriptFile()`.
Make `lluau::dostring()` accept an optional vector of script argument strings.
Following PUC-Rio Lua convention, pass these arguments into a Lua script as
the predefined global `arg`, and also as the script's `...` argument.
`LuaState::expr()` also accepts and passes through script argument strings.
Change the log tag for the Lua script interruption message: if we want it, we
can still enable it, but we don't necessarily want it along with all other
"Lua" DEBUG messages.
Remove `LuaState::script_finished_fn`, which isn't used any more. Also remove
the corresponding `LLLUAmanager::script_finished_fn`. This allows us to
simplify `~LuaState()` slightly, as well as the parameter signatures for
`LLLUAmanager::runScriptFile()` and `runScriptLine()`.
