-============================================
-libtmt - a simple terminal emulation library
-============================================
-
-libtmt is the Tiny Mock Terminal Library.  It provides emulation of a classic
-smart text terminal, by maintaining an in-memory screen image.  Sending text
-and command sequences to libtmt causes it to update this in-memory image,
-which can then be examined and rendered however the user sees fit.
-
-The imagined primary goal for libtmt is to for terminal emulators and
-multiplexers; it provides the terminal emulation layer for the `mtm`_
-terminal multiplexer, for example. Other uses include screen-scraping and
-automated test harnesses.
-
-libtmt is similar in purpose to `libtsm`_, but considerably smaller (500
-lines versus 6500 lines). libtmt is also, in this author's humble opinion,
-considerably easier to use.
-
-.. _`mtm`: https://github.com/deadpixi/mtm
-.. _`libtsm`: https://www.freedesktop.org/wiki/Software/kmscon/libtsm/
-
-Major Features and Advantages
-=============================
-
-Works Out-of-the-Box
-    libtmt emulates a well-known terminal type (`ansi`), the definition of
-    which has been in the terminfo database since at least 1995.  There's no
-    need to install a custom terminfo entry.  There's no claiming to be an
-    xterm but only emulating a small subset of its features. Any program
-    using terminfo works automatically: this includes vim, emacs, mc,
-    cmus, nano, nethack, ...
-
-Portable
-    Written in pure C99.
-    Optionally, the POSIX-mandated `wcwidth` function can be used, which
-    provides minimal support for combining characters.
-
-Small
-    Less than 500 lines of C, including comments and whitespace.
-
-Free
-    Released under a BSD-style license, free for commercial and
-    non-commerical use, with no restrictions on source code release or
-    redistribution.
-
-Simple
-    Only 8 functions to learn, and really you can get by with 6!
-
-International
-    libtmt internally uses wide characters exclusively, and uses your C
-    library's multibyte encoding functions.
-    This means that the library automatically supports any encoding that
-    your operating system does.
-
-How to Use libtmt
-=================
-
-libtmt is a single C file and a single header.  Just include these files
-in your project and you should be good to go.
-
-By default, libtmt uses only ISO standard C99 features,
-but see `Compile-Time Options`_ below.
-
-Example Code
-------------
-
-Below is a simple program fragment giving the flavor of libtmt.
-Note that another good example is the `mtm`_ terminal multiplexer:
-
-.. _`mtm`: https://github.com/deadpixi/mtm
-
-.. code:: c
-
-    #include <stdio.h>
-    #include <stdlib.h>
-    #include "tmt.h"
-
-    /* Forward declaration of a callback.
-     * libtmt will call this function when the terminal's state changes.
-     */
-    void callback(tmt_msg_t m, TMT *vt, const void *a, void *p);
-
-    int
-    main(void)
-    {
-        /* Open a virtual terminal with 2 lines and 10 columns.
-         * The first NULL is just a pointer that will be provided to the
-         * callback; it can be anything. The second NULL specifies that
-         * we want to use the default Alternate Character Set; this
-         * could be a pointer to a wide string that has the desired
-         * characters to be displayed when in ACS mode.
-         */
-        TMT *vt = tmt_open(2, 10, callback, NULL, NULL);
-        if (!vt)
-            return perror("could not allocate terminal"), EXIT_FAILURE;
-
-        /* Write some text to the terminal, using escape sequences to
-         * use a bold rendition.
-         *
-         * The final argument is the length of the input; 0 means that
-         * libtmt will determine the length dynamically using strlen.
-         */
-        tmt_write(vt, "\033[1mhello, world (in bold!)\033[0m", 0);
-
-        /* Writing input to the virtual terminal can (and in this case, did)
-         * call the callback letting us know the screen was updated. See the
-         * callback below to see how that works.
-         */
-        tmt_close(vt);

-Functions
----------
-
-`TMT *tmt_open(size_t nrows, size_t ncols, TMTCALLBACK cb, VOID *p, const wchar *acs);`
-    Creates a new virtual terminal, with `nrows` rows and `ncols` columns.
-    The callback `cb` will be called on updates, and passed `p` as a final
-    argument. See the definition of `tmt_msg_t` above for possible values
-    of each argument to the callback.
-
-    Terminals must have a size of at least two rows and two columns.
-
-    `acs` specifies the characters to use when in Alternate Character Set
-    (ACS) mode. The default string (used if `NULL` is specified) is::
-
-         L"><^v#+:o##+++++~---_++++|<>*!fo"
-
-    See `Alternate Character Set`_ for more information.
-
-    Note that the callback must be ready to be called immediately, as
-    it will be called after initialization of the terminal is done, but
-    before the call to `tmt_open` returns.
-
-`void tmt_close(TMT *vt)`
-    Close and free all resources associated with `vt`.
-
-`bool tmt_resize(TMT *vt, size_t nrows, size_t ncols)`
-    Resize the virtual terminal to have `nrows` rows and `ncols` columns.
-    The contents of the area in common between the two sizes will be preserved.
-
-    Terminals must have a size of at least two rows and two columns.
-
-    If this function returns false, the resize failed (only possible in
-    out-of-memory conditions or invalid sizes). If this happens, the terminal
-    is trashed and the only valid operation is the close the terminal.
-
-`void tmt_write(TMT *vt, const char *s, size_t n);`
-    Write the provided string to the terminal, interpreting any escape
-    sequences contained threin, and update the screen image. The last
-    argument is the length of the input. If set to 0, the length is
-    determined using `strlen`.
-
-    The terminal's callback function may be invoked one or more times before
-    a call to this function returns.
-
-    The string is converted internally to a wide-character string using the
-    system's current multibyte encoding. Each terminal maintains a private
-    multibyte decoding state, and correctly handles mulitbyte characters that
-    span multiple calls to this function (that is, the final byte(s) of `s`
-    may be a partial mulitbyte character to be completed on the next call).
-
-`const TMTSCREEN *tmt_screen(const TMT *vt);`
-    Returns a pointer to the terminal's screen image.
-
-`const TMTPOINT *tmt_cursor(cosnt TMT *vt);`
-    Returns a pointer to the terminal's cursor position.
-
-`void tmt_clean(TMT *vt);`
-    Call this after receiving a `TMT_MSG_UPDATE` or `TMT_MSG_MOVED` callback
-    to let the library know that the program has handled all reported changes
-    to the screen image.
-
-`void tmt_reset(TMT *vt);`
-    Resets the virtual terminal to its default state (colors, multibyte
-    decoding state, rendition, etc).
-
-Special Keys
-------------
-
-To send special keys to a program that is using libtmt for its display,
-write one of the `TMT_KEY_*` strings to that program's standard input
-(*not* to libtmt; it makes no sense to send any of these constants to
-libtmt itself).
-
-The following macros are defined, and are all constant strings:
-
-- TMT_KEY_UP
-- TMT_KEY_DOWN
-- TMT_KEY_RIGHT
-- TMT_KEY_LEFT
-- TMT_KEY_HOME
-- TMT_KEY_END
-- TMT_KEY_INSERT
-- TMT_KEY_BACKSPACE
-- TMT_KEY_ESCAPE
-- TMT_KEY_BACK_TAB
-- TMT_KEY_PAGE_UP
-- TMT_KEY_PAGE_DOWN
-- TMT_KEY_F1 through TMT_KEY_F10
-
-Note also that the classic PC console sent the enter key as
-a carriage return, not a linefeed. Many programs don't care,
-but some do.
-
-Compile-Time Options
---------------------
-
-There are two preprocessor macros that affect libtmt:
-
-`TMT_INVALID_CHAR`
-    Define this to a wide-character. This character will be added to
-    the virtual display when an invalid multibyte character sequence
-    is encountered.
-
-    By default (if you don't define it as something else before compiling),
-    this is `((wchar_t)0xfffd)`, which is the codepoint for the Unicode
-    'REPLACEMENT CHARACTER'. Note that your system might not use Unicode,
-    and its wide-character type might not be able to store a constant as
-    large as `0xfffd`, in which case you'll want to use an alternative.
-
-`TMT_HAS_WCWIDTH`
-    By default, libtmt uses only standard C99 features.  If you define
-    TMT_HAS_WCWIDTH before compiling, libtmt will use the POSIX `wcwidth`
-    function to detect combining characters.
-
-    Note that combining characters are still not handled particularly
-    well, regardless of whether this was defined. Also note that what
-    your C library's `wcwidth` considers a combining character and what
-    the written language in question considers one could be different.
-
-Alternate Character Set
------------------------
-
-The terminal can be switched to and from its "Alternate Character Set" (ACS)
-using escape sequences. The ACS traditionally contained box-drawing and other
-semigraphic characters.
-
-The characters in the ACS are configurable at runtime, by passing a wide string
-to `tmt_open`. The default if none is provided (i.e. the argument is `NULL`)
-uses ASCII characters to approximate the traditional characters.
-
-The string passed to `tmt_open` must be 31 characters long. The characters,
-and their default ASCII-safe values, are in order:
-
-- RIGHT ARROW ">"
-- LEFT ARROW "<"
-- UP ARROW "^"
-- DOWN ARROW "v"
-- BLOCK "#"
-- DIAMOND "+"
-- CHECKERBOARD "#"
-- DEGREE "o"
-- PLUS/MINUS "+"
-- BOARD ":"
-- LOWER RIGHT CORNER "+"
-- UPPER RIGHT CORNER "+"
-- UPPER LEFT CORNER "+"
-- LOWER LEFT CORNER "+"
-- CROSS "+"
-- SCAN LINE 1 "~"
-- SCAN LINE 3 "-"
-- HORIZONTAL LINE "-"
-- SCAN LINE 7 "-"
-- SCAN LINE 9 "_"
-- LEFT TEE "+"
-- RIGHT TEE "+"
-- BOTTOM TEE "+"
-- TOP TEE "+"
-- VERTICAL LINE "|"
-- LESS THAN OR EQUAL "<"
-- GREATER THAN OR EQUAL ">"
-- PI "*"
-- NOT EQUAL "!"
-- POUND STERLING "f"
-- BULLET "o"
-
-If your system's wide character type's character set corresponds to the
-Universal Character Set (UCS/Unicode), the following wide string is a
-good option to use::
-
-    L"→←↑↓■◆▒°±▒┘┐┌└┼⎺───⎽├┤┴┬│≤≥π≠£•"
-
-**Note that multibyte decoding is disabled in ACS mode.** The traditional
-implementations of the "ansi" terminal type (i.e. IBM PCs and compatibles)
-had no concept of multibyte encodings and used the character codes
-outside the ASCII range for various special semigraphic characters.
-(Technically they had an entire alternate character set as well via the
-code page mechanism, but that's beyond the scope of this explanation.)
-
-The end result is that the terminfo definition of "ansi" sends characters
-with the high bit set when in ACS mode. This breaks several multibyte
-encoding schemes (including, most importantly, UTF-8).
-
-As a result, libtmt does not attempt to decode multibyte characters in
-ACS mode, since that would break the multibyte encoding, the semigraphic
-characters, or both.
-
-In general this isn't a problem, since programs explicitly switch to and
-from ACS mode using escape sequences.
-
-When in ACS mode, bytes that are not special members of the alternate
-character set (that is, bytes not mapped to the string provided to
-`tmt_open`) are passed unchanged to the terminal.
-
-Supported Input and Escape Sequences
-====================================
-
-Internally libtmt uses your C library's/compiler's idea of a wide character
-for all characters, so you should be able to use whatever characters you want
-when writing to the virtual terminal (but see `Alternate Character Set`_).
-
-The following escape sequences are recognized and will be processed
-specially.
-
-In the descriptions below, "ESC" means a literal escape character and "Ps"
-means zero or more decimal numeric arguments separated by semicolons.
-In descriptions "P1", "P2", etc, refer to the first parameter, second
-parameter, and so on.  If a required parameter is omitted, it defaults
-to the smallest meaningful value (zero if the command accepts zero as
-an argument, one otherwise).  Any number of parameters may be passed,
-but any after the first eight are ignored.
-
-Unless explicitly stated below, cursor motions past the edges of the screen
-are ignored and do not result in scrolling.  When characters are moved,
-the spaces left behind are filled with blanks and any characters moved
-off the edges of the screen are lost.

-==============   =================================================
-
-Other escape sequences are recognized but ignored.  This includes escape
-sequences for switching out codesets (officially, all code sets are defined
-as equivalent in libtmt), and the various "Media Copy" escape sequences
-used to print output on paper (officially, there is no printer attached
-to libtmt).
-
-Additionally, "?" characters are stripped out of escape sequence parameter
-lists for compatibility purposes.
-
-Known Issues
-============
-
-- Combining characters are "handled" by ignoring them
-  (when compiled with `TMT_HAS_WCWIDTH`) or by printing them separately.
-- Double-width characters are rendered as single-width invalid
-  characters.
-- The documentation and error messages are available only in English.
-
-Frequently Asked Questions
-==========================
-
-What programs work with libtmt?
--------------------------------
-
-Pretty much all of them.  Any program that doesn't assume what terminal
-it's running under should work without problem; this includes any program
-that uses the terminfo, termcap, or (pd|n)?curses libraries.  Any program
-that assumes it's running under some specific terminal might fail if its
-assumption is wrong, and not just under libtmt.
-
-I've tested quite a few applications in libtmt and they've worked flawlessly:
-vim, GNU emacs, nano, cmus, mc (Midnight Commander), and others just work
-with no changes.
-
-What programs don't work with libtmt?
--------------------------------------
-
-Breakage with libtmt is of two kinds: breakage due to assuming a terminal
-type, and reduced functionality.
-
-In all my testing, I only found one program that didn't work correctly by
-default with libtmt: recent versions of Debian's `apt`_ assume a terminal
-with definable scrolling regions to draw a fancy progress bar during
-package installation.  Using apt in its default configuration in libtmt will
-result in a corrupted display (that can be fixed by clearing the screen).
-
-.. _`apt`: https://wiki.debian.org/Apt
-
-In my honest opinion, this is a bug in apt: it shouldn't assume the type
-of terminal it's running in.
-
-The second kind of breakage is when not all of a program's features are
-available.  The biggest missing feature here is mouse support: libtmt
-doesn't, and probably never will, support mouse tracking.  I know of many
-programs that *can* use mouse tracking in a terminal, but I don't know
-of any that *require* it.  Most (if not all?) programs of this kind would
-still be completely usable in libtmt.
