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.

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.

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. + +License +------- + +Copyright (c) 2017 Rob King +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are met: + +- Redistributions of source code must retain the above copyright + notice, this list of conditions and the following disclaimer. +- Redistributions in binary form must reproduce the above copyright + notice, this list of conditions and the following disclaimer in the + documentation and/or other materials provided with the distribution. +- Neither the name of the copyright holder nor the + names of contributors may be used to endorse or promote products + derived from this software without specific prior written permission. + +THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +"AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +A PARTICULAR PURPOSE ARE DISCLAIMED.
