* | tui: Improvements to RGB colour support.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | | | | | | | The details are in the on-line help under :help true-color . The brief precis is that nvim is (I hope.) converging with tmux and libvte. It is taking the same approach with setrgbf and setrgbb terminfo capabilities that it does with the Ss and Se terminfo capabilities.
* | tui: Refactor built-in teminfo records.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | No change to their contents, but make the Big Blocks Of Numbers half as wide but twice as deep, in order to accomodate house style.
* | tui: Update fallback terminfo records.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | Replace the 8-color xterm from unibilium with the 256-colour one from terminfo. Add a fallback record for suckless terminal.

* | tui: More refactoring, and improvements to cursor shape support.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | | | | | | | The details are in the on-line help under :help cursor-shape . The brief precis is that nvim is following the lead of tmux, and going beyond what tmux does to make cursor shape changes work on a broad range of terminals. This includes on tmux itself, which is no longer bypassed.
* | tui: Split fix_terminfo() up and refactor.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are now a few built-in terminfo entries, taken either from unibilium or ncurses terminfo, for falling back upon when there is no terminfo database or when it is missing stuff. In an ideal world, these would be in unibilium itself. The ultimate fallback, for no terminfo database and no built-in terminfo record that matches the terminal type, is now the "ansi" terminal type; so unknown terminal types are now considered to have at minimum the basic ECMA-48 colour, motion, and editing capabilities. The terminfo records are just blobs, raw images of the equivalent terminfo file created with the od command. No longer are incomplete terminfo records built up with code. These blobs are the full, real, records; already built. The post-processing of the terminfo record, once found, is split into the part where we fix known errors and deficiencies in terminfo, and the part where we add extensions that we need that terminfo does not define capabilities for. In an ideal world, the former would be a no-op. No part of the TUI layer apart from these is aware of terminal type or has conditional code based upon checking environment variables at runtime. It is all pre-calculated and written into unibilium (or the TUIData object) at initialization time. This is fairly aggressive about turning on 256-colour and true colour support. This also positively decodes genuine xterm for turning on DECSLRM use, rather than assuming that anything that says that it is xterm is actually xterm, fixing scrolling problems with vertically split windows.
* | tui: Fix cursor motion clear screen bug visible on line #1 in redraws.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | The clear_screen capability moves the cursor position. This needs to be accounted for.
* | tui: Coding style changes onlyJonathan de Boyne Pollard2017-06-03
| | | | | | | | Per warnings about house style from automated tools.
* | tui: Optimize more cursor motionsJonathan de Boyne Pollard2017-06-03
| | | | | | | | A slight improvement on the CR optimization for some edge cases.
* | tui: Use what scrolling PuTTY has.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | | | PuTTY does not implement DECLRMM or DECSLRM, but it does implement DECSTBM. So allow using PuTTY terminal scrolling when the scroll rectangle is the full width of the terminal.
* | tui: Optimize cursor motionsJonathan de Boyne Pollard2017-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of emitting CUP in several places each with their own poor local optimizations, funnel all cursor motion through a central place. This central function performs the same optimization for every place that needs to move the cursor, and implements a better set of optimizations: * Emit CUU/CUD/CUF/CUB instad of CUP when they are likely shorter. * Use BS and LF when they are shorter than CUB and CUD. * Use CR for quick returns to column zero. * If printing the next few characters is shorter than a rightwards motion, then just write out the characters.
* | tui: Eliminate superfluous SGR resets.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | Track whether the terminal is in no attribute mode, assuming that it starts this way, and do not attempt to reset back to that mode if already in it.
* | tui: document fix_terminfo()'s several tasksJonathan de Boyne Pollard2017-06-03
| |
* | Separate 16- and 256- colour control sequences and tidy up some redundancy.Jonathan de Boyne Pollard2017-06-03
| |
* | Change TUI resize to use an extended terminal capability.Jonathan de Boyne Pollard2017-06-03
| | | | | | | | | | ... rather than hardwiring the string and testing the terminal type every time the screen is re-sized.
* | tui: Improve scrolling mechanism.Jonathan de Boyne Pollard2017-05-23
| | | | | | | | | | | | Respect the BGE flag from terminfo rather than guessing that it is always off. Emit DECLRMM and DECSLRM (or equivalent) to properly define the scroll rectangle.
* | tui: Reset the scroll region when resizing.Jonathan de Boyne Pollard2017-05-23
| | | | | | | | | | | | | | | | | | | | DECSLPP is explicitly documented as not affecting the scroll region. The dtterm extension is not as well documented, but it is safer than not to assume that it operates similarly. This also eliminates a pointlessly repeated test from tui_scroll(). It additionally uses a non-parameterized DECSTBM sequence when attempting to reset back to whole-screen scrolling.
* | tui: resize: use an extended terminal capabilityJonathan de Boyne Pollard2017-05-23
| | | | | | | | | | ... rather than hardwiring the string and testing the terminal type every time the screen is re-sized.
* | tui: Only use dtterm's extension where supported.Jonathan de Boyne Pollard2017-05-23
| | | | | | | | | | | | | | | | | | | | | | | | This limits the use of dtterm's extension to DECSLPP to only those terminal types where it is known to be supported. Because it can be potentially understood as genuine DECSLPP sequence, setting the number of lines to a number larger than 25, which of course can cause confusion (especially if it is the width parameter that results in this) only use it on terminals that are known to support the dtterm extension. rxvt (Unicode) also understands dtterm's extension.
* | tui.c: Initialize TUI input component only once. (#6784)Justin M. Keyes2017-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | term_input_start should be called only once.

* | tui: Also fix "linux*" terminfo entries. #6673Jonathan de Boyne Pollard2017-05-04
| | | | | | | | | | | | | | | | | | | | | | The terminfo entry for linux only advertises 8 colours, but nvim tries to make it display 16 colours anyway, resulting in erroneous SGR control sequences for colours 8 and above. The Linux kernel terminal emulator itself has actually understood the 256-colour control sequences since version 4.8 and the 16-colour control sequences since version 4.9. Thus we apply the same terminfo fixup as we apply for *xterm* and *256*, to emit the 16-colour and 256-colour control sequences even if terminfo's setaf and setab do not advertise them.

* | win: Terminal UI #6315Rui Abreu Ferreira2017-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For CI builds unibilium is provided through msys2 packages, and libtermkey is built from source in third-party from equalsraf/libtermkey. In Windows we cannot read terminal input from the stdin file descriptor, instead use libuv's uv_tty API. It should handle key input and encoding. The UI suspend is not implemented for Windows, because the SIGSTP/SIGCONT do not exist in windows. Currently this is a NOOP. Closes #3902 Closes #6640

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Asynchronous API functions are served immediately, which means pending input could change the state of Nvim shortly after an async API function result is returned. nvim_get_mode() is different: - If RPCs are known to be blocked, it responds immediately (without flushing the input/event queue) - else it is handled just-in-time before waiting for input, after pending input was processed. This makes the result more reliable (but not perfect). Internally this is handled as a special case, but _semantically_ nothing has changed: API users never know when input flushes, so this internal special-case doesn't violate that. As far as API users are concerned, nvim_get_mode() is just another asynchronous API function. In all cases nvim_get_mode() never blocks for more than the time it takes to flush the input/event queue (~µs). Note: This doesn't address #6166; nvim_get_mode() will provoke #6166 if e.g. `d` is operator-pending. Closes #6159
