2022-08-04	Use C++ casts, nullptr.	John Ankarström

2022-08-04	Add comments.	John Ankarström

2022-08-03	Use Pascal case for all functions.	John Ankarström

2022-08-03	Split common.h to util.h, wcharptr.h and win.h.	John Ankarström

2022-08-02	Improve wstring_owner, rename to wchar_ptr.	John Ankarström
	The user-defined conversion function makes the interface a lot simpler AND safer.
2022-07-31	Make WsoFromSz and WsoCopy static member functions of wstring_owner.	John Ankarström

2022-07-31	Limit use of Hungarian notation.	John Ankarström
	I don't hate Hungarian notation. It has some very nice qualities. But it also adds a lot of typing. That said, not using it feels a bit... unsafe. I might go back on this decision. We'll see.
2022-07-30	Add wstring_owner, replacing std::wstring.	John Ankarström
	std::basic_string is nice, but it is not very ergonomic if everything you really need is to automatically free C strings at end of scope. I suppose I could have used std::unique_ptr for this, but I suspect the ergonomics would be worse.
2022-07-30	Add non-throwing variants of Query methods.	John Ankarström
	Pl has also been refactored, so that the unnecessary throw and catch have been removed.
2022-07-26	Use 's' instead of 'str' for as prefix for managed strings.	John Ankarström

2022-07-26	Remove ANSI compatibility.	John Ankarström
	Even though it is a fun challange in many ways, I think that, realistically, it is probably not worth the complexity. The Prolog backend isn't ANSI-compatible either.
2022-07-24	Fix PL_get_tchars.	John Ankarström
	See c6cd2f1.
2022-07-24	Add const.	John Ankarström

2022-07-23	Fix display of Unicode text.	John Ankarström
	Turns out that SWI-Prolog's wide string functions, which I started using in 03fe361, do not convert between narrow Prolog atoms and wide C strings, as I mistakenly thought. Instead, they work with wide Prolog atoms. In hindsight, it is not surprising.
2022-07-20	Improve ANSI compatibility.	John Ankarström
	This improves upon 79d4fa6. Actually, ANSI compatibility may be desirable, as recent work has been done to make the A versions of Windows API functions work with UTF-8.
2022-07-20	Simplify templates.	John Ankarström

2022-07-19	Formatting.	John Ankarström

2022-07-19	Use Prolog string buffer marks.	John Ankarström
	Speaking of unclear documentation, it is not obvious whether it is necessary for programs calling into Prolog to manually mark and release strings. I suppose that it should be, if the same logic that applies to terms apply to strings. On the other hand, the stack in which the strings are stored belongs to Prolog, and there is nothing that would prevent Prolog from cleaning up the strings when called at a later time. I am not sure. But better safe than sorry, I guess. The Mark class acts like the Frame class. The constructor and destructor are equivalent to the PL_STRINGS_MARK and PL_STRINGS_RELEASE macros. Unlike for 34c3280, I did not notice any differences in memory usage after this change. Perhaps that is because it has no effect; perhaps it is because Prolog's stack is very big.
2022-07-19	Fix Prolog memory leaks.	John Ankarström
	Apparently foreign frames ARE needed when calling Prolog from C. The official documentation is very terse and could make this clearer. To summarize, whenever a term is created (e.g., PL_new_term_refs), its reference count is increased by one. It is garbage-collected when its reference count hits zero. But the reference count is never decreased unless (a) control returns to Prolog after executing a foreign predicate -- which does not happen in my application -- or (b) the foreign frame in which the term was created is closed. In other words, terms must be created within a foreign frame. This is achieved by initializing a Frame object before creating the term and destroying it once the term has served its purpose. The destructor for Frame does not DISCARD the frame, only CLOSE it. The former would also invalidate all data bound by the terms, which is usually undesirable.
2022-07-18	Solve compiler warnings.	John Ankarström

2022-07-18	Avoid leak in Prolog interface.	John Ankarström
	PL_new_atom(_wchars) creates an atom with a reference count of one, which is never decreased, and the atom is thus never garbage collected.
2022-07-17	Prefer f() over f(void).	John Ankarström
	f(void) is a C-ism that is valid but unnecessary in C++.
2022-07-17	Update type names and variable prefixes.	John Ankarström

2022-07-17	Name function arguments in headers.	John Ankarström
	This is obviously a lot less obtuse.
2022-07-17	Add const to pointers, update spacing.	John Ankarström
	It seems that "right-spaced" pointers are more widely used among C++ programmers.
2022-07-17	Add const to places.	John Ankarström
	Note that I did NOT add const to non-pointer/non-reference arguments in function declarations (without a following definition), as they do not mean anything there.
2022-07-17	Use SWI-Prolog's wide-character functions.	John Ankarström
	This avoids the use of TsmFromSz.
2022-07-16	Formatting.	John Ankarström

2022-07-16	Rewrite TszFromSz as TsmFromSz.	John Ankarström
	I.e. using std::basic_string<TCHAR> instead of TCHAR *. This removes all unmanaged frees.
2022-07-15	Split defs.h into separate header files.	John Ankarström
	This is feasible now that the makedeps script exists to automatically manage build dependencies (see 6034fe2, d00f8b3).
