+============================================
+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);
+ return EXIT_SUCCESS;
+ }
+
+ void
+ callback(tmt_msg_t m, TMT *vt, const void *a, void *p)
+ {
+ /* grab a pointer to the virtual screen */
+ const TMTSCREEN *s = tmt_screen(vt);
+ const TMTPOINT *c = tmt_cursor(vt);
+
+ switch (m){
+ case TMT_MSG_BELL:
+ /* the terminal is requesting that we ring the bell/flash the
+ * screen/do whatever ^G is supposed to do; a is NULL
+ */
+ printf("bing!\n");
+ break;
+
+ case TMT_MSG_UPDATE:
+ /* the screen image changed; a is a pointer to the TMTSCREEN */
+ for (size_t r = 0; r < s->nline; r++){
+ if (s->lines[r]->dirty){
+ for (size_t c = 0; c < s->ncol; c++){
+ printf("contents of %zd,%zd: %lc (%s bold)\n", r, c,
+ s->lines[r]->chars[c].c,
+ s->lines[r]->chars[c].a.bold? "is" : "is not");
+ }
+ }
+ }
+
+ /* let tmt know we've redrawn the screen */
+ tmt_clean(vt);
+ break;
+
+ case TMT_MSG_ANSWER:
+ /* the terminal has a response to give to the program; a is a
+ * pointer to a string */
+ printf("terminal answered %s\n", (const char *)a);
+ break;
+
+ case TMT_MSG_MOVED:
+ /* the cursor moved; a is a pointer to the cursor's TMTPOINT */
+ printf("cursor is now at %zd,%zd\n", c->r, c->c);
+ break;

+ 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.
