* TUI: Konsole DECSCUSR fixup (#9423)Justin M. Keyes2019-01-01
| | | | | | | Apparently Konsole's terminfo is still broken. ref #9364 closes #9420

| * win/TUI: ConEmu: get back_color_erase from terminfoJustin M. Keyes2018-12-30
| | | | | | | | | | | | We already set back_color_erase in our builtin terminfo (terminfo_defs.h:conemu_terminfo), so we don't need to set it explicitly in patch_terminfo_bugs().
| * refactor: Extract os_tty_guess_term()Justin M. Keyes2018-12-30
| | | | | | | | | | - Also remove feature-detection of uv_set_vterm_state(): instead, on Windows we always require libuv to have that function.

| * | win/TUI: SetConsoleMode() to override libuv #9094erw72018-12-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use uv_set_vterm_state() to override libuv's guess. See https://github.com/libuv/libuv/pull/1873/ for discussion. This commit uses a terminal-detection approach based on GetProcessImageFileNameW(...), which will be reverted in the following commit. The approach was intended to handle the case of running in winpty (:terminal), but we will add $NVIM env var for that. Also add some support for ConEmu, cygwin.
* | | TUI: enter/exit alternate screen with "title stacking" (#9407)Justin M. Keyes2018-12-29
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Works in iTerm2 and xterm. - patch_terminfo_bugs(): Add title-stacking sequences (\e[22t and \e[23t) to the overrides for iTerm2 and xterm. - Note: the builtins (terminfo_defs.h) for `iterm_256colour_terminfo` and `xterm_256colour_terminfo` already include the sequences. Test case (title should be "foo" after the final :q): TERM=iterm2 nvim -u NONE +'set title titleold=foo' :q TERM=iterm2 nvim -u NONE +'set title titlestring=zub' :q closes #4063

* | TUI: detect BSD vt consoleJustin M. Keyes2018-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSD console sets TERM=xterm, but it does not support xterm features like cursor-shaping. GUI terminals typically set TERM=xterm-256color, so on FreeBSD we can guess that TERM=xterm is the degraded vt. OpenBSD console sets TERM=vt220 https://github.com/openbsd/src/blob/master/etc/etc.amd64/ttys NetBSD console sets TERM=vt100 https://github.com/NetBSD/src/blob/trunk/etc/etc.amd64/ttys closes #8644

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes https://github.com/neovim/neovim/issues/9270 --- Background info per egmontkob: https://github.com/neovim/neovim/issues/9270#issuecomment-441979176 For undercurl, the newly invented escape sequence is `4:3` strictly with a colon, as with a semicolon it means single underlined and italic. For colored underline, the newly invented escape sequence `58:...` is meant to follow the pattern of `38` and `48`. [ITU T.416](https://www.itu.int/rec/T-REC-T.416-199303-I/en) § 13.1.8 clearly specifies the colon only as the separator (and the well-known ECMA-48 § 8.3.117 just points to this standard). Using semicolon instead was/is a frequent misinterpretation of this standard, and is commonly used in the wild – for 38 and 48. More and more emulators are catching up and beginning to support colon, in addition to semicolon. Semicolon is pretty fragile; in case an emulator doesn't recognize a sequence (let's say doesn't recognize the new extension of `58`), subsequent numbers are interpreted as other attributes. E.g. if 256-color mode is chosen then the next numeric parameter is `5` which turns on blinking. So, luckily, the standard is the technically better solution, the frequent practice of using semicolons is technically the worse. Therefore the direction we should be going is clear. I believe it's a fair requirement for anyone adopting colored underline to support colons too, and it's a reasonable move from applications to slightly push the world forward, force developers to catch up with the recent changes, that is: 1) recognize and at least ignore colon-delimited parameters even if they aren't supported, 2) recognize and support colon wherever they support the nonstandard semicolon instead. Should you come across any terminal emulator that supports 58 with semicolons but not with colons, I think the cleanest you can do is report a bug against them and ignore the problem; they should fix it. It's yet another common misunderstanding that the truecolor syntax is `38`/`48`/`58` followed by `:2:rrr:ggg:bbb`. The wording of T.416 is terrible, but if you read carefully, there's another parameter of color-space-id preceding the three color channels. Assuming you don't care about color-space-id, the syntax is `38`/`48`/`58` followed by `:2::rrr:ggg:bbb` and of course the trailing `m`. This is only for true-color, the 256-color format doesn't have such a parameter, it's `38`/`48`/`58` followed by `:5:index` and the final `m`.
* | TUI: support TERM=nsterm (#9244)Justin M. Keyes2018-11-18
| | | | | | | | | | | | | | `:help $TERM` recommends TERM=nsterm for Terminal.app but we did not actually support it. NB: We don't include a builtin term for Terminal.app, presumably because nsterm is commonly available on most systems (`infocmp nsterm`).

* | UI/TUI: improvements and cleanups for scrolling and clearingBjörn Linse2018-11-11
|/ | | | | | | | | | | | - TUI: _never_ rely on BCE for implicit clearing, only explicit commands. - TUI: use unibi_erase_chars when possible. - TUI: use end-exclusive ranges for invalid and cleared areas - screen: scrolling leaves scrolled in aree undefined. This is a conservative change, a client assuming the old semantics will still behave correctly. - screen: factor out vsep handling from line drawing. This is needed anyway for the multigrid refactor. - screen: simplifications of win_do_lines

|\ | | | | TUI cursor fixes: avoid memory errors after resize with invalid cursor position
| * TUI: delete "first-row" workaround after resizeBjörn Linse2018-10-06
| | | | | | | | | | This was caused by cursor position being invalid right after tui_grid_resize, which is now fixed
| * TUI: always use safe cursor movement after resizeBjörn Linse2018-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old code could lead to a memory error in the following situation: 0. The previous cursor position was row 50 since before, on a grid larger than 50 rows. 1. grid_resize changes the grid height to 40, and invalidly assumes the resize moved the physical cursor to row 0 2. Some event used a operation that could move the cursor (such as clear), and then reset the cursor to the "true" position row 50 (pointless after #8221, but I forgot to remove it) 3. raw_line/cheap_to_print is invoked, and tries to inspect the grid at row 50 (memory error) 4. grid_cursor_goto would have been called at this point, and set a valid cursor position 0-39.

* | tui: eliminate scrolling region data structureBjörn Linse2018-09-27
| | | | | | | | | | | | | | | | | | The scrolling region is always local to a single grid_scroll event, use local variables and parameters instead. The invocation of reset_scroll_region in grid_resize is cargo-culted to use margin reset under exactly the same circumstances, not sure if it is necessary though.

* TUI: Reset cursor color when applicable #8572Yichao Zhou2018-09-22
| | | | | | | | | | | | | | | | | | | | | | | | Resets the TUI cursor color if: - current 'guicursor' mode does not specify a highlight group - cursor highlight group has "inverse" or "reverse" flag - on Nvim exit We interpret, "inverse" to mean "default cursor". Example: hi Cursor guifg=bg guibg=fg set termguicolors set guicursor=n-v-c-sm:block,i-ci-ve:ver25-Cursor,r-cr-o:hor20 * When the cursor shape is block, its color will be "inverse" * When the cursor shape is I-beam, its color will be `hi Cursor`. This is useful e.g. to prevent `set listchars=eol:¬` causing your cursor color to a low contrast color in insert mode because you cursor are often at EOL in insert mode. close #8572
* cleanup/TUI: remove old unused code #9013Justin M. Keyes2018-09-19
| | | | | | | | - Checks for ECHOE, ICANON were left over from Vim code. We already reference the symbols elsewhere without checking. - newline_on_exit, intr_char: Both are vestigial remnants of Vim 4.x, not implemented in Nvim. intr_char is a termios/stty feature, it's probably not useful because users have other ways to configure their terminals.
* TUI: Skip redundant "stop" event (macOS kernel panic) (#9007)Justin M. Keyes2018-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the TUI suspends (:suspend, CTRL-z) it calls tui_terminal_stop (but does NOT set `ui->data=NULL`, so `tui_is_stopped` returns false). If the host terminal dies, it sends SIGCONT, SIGHUP (usually in that order): ERROR 2018-09-16T19:30:17.065 25821 suspend_event:1153: SIGCONT ERROR 2018-09-16T19:30:17.065 25821 on_signal:162: SIGHUP ERROR 2018-09-16T19:30:17.155 25821 on_signal:162: SIGHUP Race: if SIGHUP is handled before SIGCONT, it calls ui_builtin_stop() which schedules tui_stop before the TUI was resumed? libuv uv_close() aborts if the handle is already closed/closing.

* tui: Hint wrapped lines to terminals.Ricky Zhou2018-09-03
| | | | | | | | | | | | | | | | Previously, when neovim would wrap a line across multiple lines, terminal emulators could not detect that the lines represent a single wrapped line as opposed to several separate lines. As a result, many terminals' selection/copying functionality would treat a wrapped line as several newline-delimited lines. Fix this by reenabling a "special trick" from Vim. When a line is wrapped, write the last character of that line followed by the first character of the next line to the terminal. This hints to the terminal that the next line is a continuation of the current line. Extends the raw_line event with a "wrap" parameter which controls when to do wrap hinting.
