It also favors +portability, and includes support for all POSIX systems. + +The database is also flexible & extensible, and can modified by either running +a program to build the entire database, or an entry for just a single terminal. + +## More Portable + +_Tcell_ is portable to a wide variety of systems. +_Tcell_ is believed +to work with all of the systems officially supported by golang with +the exception of nacl (which lacks any kind of a terminal interface). +(Plan9 is not supported by _Tcell_, but it is experimental status only +in golang.) For all of these systems *except Solaris/illumos*, _Tcell_ +is pure Go, with no need for CGO. + +## No Async IO + +_Tcell_ is able to operate without requiring `SIGIO` signals (unlike _termbox_), +or asynchronous I/O, and can instead use standard Go file +objects and Go routines. +This means it should be safe, especially for +use with programs that use exec, or otherwise need to manipulate the +tty streams. +This model is also much closer to idiomatic Go, leading +to fewer surprises. + +## Rich Unicode & non-Unicode support + +_Tcell_ includes enhanced support for Unicode, including wide characters and +combining characters, provided your terminal can support them. +Note that +Windows terminals generally don't support the full Unicode repertoire. + +It will also convert to and from Unicode locales, so that the program +can work with UTF-8 internally, and get reasonable output in other locales. +_Tcell_ tries hard to convert to native characters on both input and output, and +on output _Tcell_ even makes use of the alternate character set to facilitate +drawing certain characters. + +## More Function Keys + +_Tcell_ also has richer support for a larger number of special keys that some terminals can send. + +## Better Color Handling + +_Tcell_ will respect your terminal's color space as specified within your terminfo +entries, so that for example attempts to emit color sequences on VT100 terminals +won't result in unintended consequences. + +In Windows mode, _Tcell_ supports 16 colors, bold, dim, and reverse, +instead of just termbox's 8 colors with reverse. (Note that there is some +conflation with bold/dim and colors.) + +_Tcell_ maps 16 colors down to 8, for terminals that need it. +(The upper 8 colors are just brighter versions of the lower 8.) + +## Better Mouse Support + +_Tcell_ supports enhanced mouse tracking mode, so your application can receive +regular mouse motion events, and wheel events, if your terminal supports it. + +## _Termbox_ Compatibility + +A compatibility layer for _termbox_ is provided in the `compat` directory. +To use it, try importing `github.com/gdamore/tcell/termbox` +instead. Most _termbox-go_ programs will probably work without further +modification. + +## Working With Unicode + +Internally Tcell uses UTF-8, just like Go. +However, Tcell understands how to +convert to and from other character sets, using the capabilities of +the `golang.org/x/text/encoding packages`. +Your application must supply +them, as the full set of the most common ones bloats the program by about 2MB. +If you're lazy, and want them all anyway, see the `encoding` sub-directory. + +## Wide & Combining Characters + +The `SetContent()` API takes a primary rune, and an optional list of combining runes. +If any of the runes is a wide (East Asian) rune occupying two cells, +then the library will skip output from the following cell, but care must be +taken in the application to avoid explicitly attempting to set content in the +next cell, otherwise the results are undefined. (Normally wide character +is displayed, and the other character is not; do not depend on that behavior.) + +Experience has shown that the vanilla Windows 8 console application does not +support any of these characters properly, but at least some options like +_ConEmu_ do support Wide characters. + +## Colors + +_Tcell_ assumes the ANSI/XTerm color model, including the 256 color map that +XTerm uses when it supports 256 colors. The terminfo guidance will be +honored, with respect to the number of colors supported. Also, only +terminals which expose ANSI style `setaf` and `setab` will support color; +if you have a color terminal that only has `setf` and `setb`, please let me +know; it wouldn't be hard to add that if there is need. + +## 24-bit Color + +_Tcell_ _supports true color_! (That is, if your terminal can support it, +_Tcell_ can accurately display 24-bit color.) + +To use 24-bit color, you need to use a terminal that supports it. Modern +xterm and similar teminal emulators can support this. As terminfo lacks any +way to describe this capability, we fabricate the capability for +terminals with names ending in `*-truecolor`. The stock distribution ships +with a database that defines `xterm-truecolor`. +To try it out, set your +`TERM` variable to `xterm-truecolor`. + +When using TrueColor, programs will display the colors that the programmer +intended, overriding any "`themes`" you may have set in your terminal +emulator. (For some cases, accurate color fidelity is more important +than respecting themes. For other cases, such as typical text apps that +only use a few colors, its more desirable to respect the themes that +the user has established.) + +If you find this undesirable, you can either use a `TERM` variable +that lacks the `TRUECOLOR` setting, or set `TCELL_TRUECOLOR=disable` in your +environment. + +## Performance + +Reasonable attempts have been made to minimize sending data to terminals, +avoiding repeated sequences or drawing the same cell on refresh updates. + +## Terminfo + +(Not relevent for Windows users.) + +The Terminfo implementation operates with two forms of database. The first +is the built-in go database, which contains a number of real database entries +that are compiled into the program directly. This should minimize calling +out to database file searches. + +The second is in the form of JSON files, that contain the same information, +which can be located either by the `$TCELLDB` environment file, `$HOME/.tcelldb`, +or is located in the Go source directory as `database.json`. + +These files (both the Go and the JSON files) can be generated using the +mkinfo.go program. If you need to regnerate the entire set for some reason, +run the mkdatabase.sh file. The generation uses the infocmp(1) program on +the system to collect the necessary information. + +The `mkinfo.go` program can also be used to generate specific database entries +for named terminals, in case your favorite terminal is missing. (If you +find that this is the case, please let me know and I'll try to add it!) + +_Tcell_ requires that the terminal support the `cup` mode of cursor addressing. +Terminals without absolute cursor addressability are not supported. +This is unlikely to be a problem; such terminals have not been mass produced +since the early 1970s. + +## Mouse Support + +Mouse support is detected via the `kmous` terminfo variable, however, +enablement/disablement and decoding mouse events is done using hard coded +sequences based on the XTerm X11 model. As of this writing all popular +terminals with mouse tracking support this model. (Full terminfo support +is not possible as terminfo sequences are not defined.) + +On Windows, the mouse works normally. + +Mouse wheel buttons on various terminals are known to work, but the support +in terminal emulators, as well as support for various buttons and +live mouse tracking, varies widely. Modern _xterm_, macOS _Terminal_, and _iTerm_ all work well. + +## Testablity + +There is a `SimulationScreen`, that can be used to simulate a real screen +for automated testing. The supplied tests do this. The simulation contains +event delivery, screen resizing support, and capabilities to inject events +and examine "`physical`" screen contents. + +## Platforms + +### POSIX (Linux, FreeBSD, macOS, Solaris, etc.) + +For mainstream systems with a suitably well defined system call interface +to tty settings, everything works using pure Go. + +For the remainder (right now means only Solaris/illumos) we use POSIX function +calls to manage termios, which implies that CGO is required on those platforms. + +### Windows + +Windows console mode applications are supported. Unfortunately _mintty_ +and other _cygwin_ style applications are not supported. + +Modern console applications like ConEmu, as well as the Windows 10 +console itself, support all the good features (resize, mouse tracking, etc.) + +I haven't figured out how to cleanly resolve the dichotomy between cygwin +style termios and the Windows Console API; it seems that perhaps nobody else +has either. If anyone has suggestions, let me know! Really, if you're +using a Windows application, you should use the native Windows console or a +fully compatible console implementation. + +### Plan9 and Native Client (Nacl) + +The nacl and plan9 platforms won't work, but compilation stubs are supplied +for folks that want to include parts of this in software targetting those +platforms. The Simulation screen works, but as Tcell doesn't know how to +allocate a real screen object on those platforms, `NewScreen()` will fail. + +If anyone has wisdom about how to improve support for either of these, +please let me know.
