- Update to latest tcell which has 24 bit Windows support
- light renderer under Windows defaults to Dark256, if possible
- Respect TCELL_TRUECOLOR
- Remove tcell 1.3 references

- Replaced time.Now().Sub() with time.Since()
- Replaced unnecessary string/byte slice conversions
- Removed obsolete return and value assignment in range loop
fzf used to print non-displayable characters (ascii code < 32) as '?',
but we will simply ignore those characters with this patch, just like
our terminals do.
\n and \r are exceptions. They will be printed as a space character.
TODO: \H should delete the preceding character, but this is not implemented.
Related: #1253
Remove code that is no longer relevant after the removal of ncurses
renderer. This commit also fixes background color issue on tcell-based
FullscreenRenderer (Windows).
It is reported that it can have an unwanted side effect of clearing the
screen on terminal emulators that do not properly support it.
Patch suggested by @arya.
Close#1011
- Update install script to download Windows binary if $TERM == cygwin
- Unset TERM if $TERM == cygwin (#933)
- Always use cmd.exe instead of $SHELL when running commands
Due to go std lib uses poller for os.File introducing in this commit:
c05b06a12d
There are two changes to watch out:
1. os.File.Fd will always return a blocking fd except on bsd.
2. os.File.Read won't return EAGAIN error for nonblocking fd.
So
For 1, we just get tty's fd in advance and then set its block mode.
For 2, we use read syscall directly to get what we wanted error(EAGAIN).
Fix issue #910.

Do not automatically decide to use alternate screen when the value of
height exceeds the height of the terminal.
# Use alternate screen
fzf
fzf --height 100%
fzf --no-height
# Still use current screen
fzf --height 10000
- Move cursor to the top-left corner when starting a command in
alternate screen
- Fix cursor position when returning to alternate screen when fzf is
running in full screen mode
Excerpt from http://www.tldp.org/HOWTO/Bash-Prompt-HOWTO/x361.html:

They are also unsupported by Neovim terminal.
Also reduce the default delay to 50ms. We should not set it to 0ms as it
breaks escape sequences on WSL. If 50ms is not enough, one can increase
the delay by setting $ESCDELAY to a larger value.
- Fix display of CJK wide characters
- Fix horizontal offset of header lines
- Add support for keys with ALT modifier, shift-tab, page-up and down
- Fix util.ExecCommand to properly parse command-line arguments
- Fix redraw on resize
- Implement Pause/Resume for execute action
- Remove runtime check of GOOS
- Change exit status to 2 when tcell failed to start
- TBD: Travis CI build for tcell renderer
- Pending. tcell cannot reliably ingest keys from tmux send-keys
