- extract logical parts to separate variables (e.g. $opts)
- put options in $opts in similar order
- move +/-m into $opts (at the end, so they won't be overridden)
- split pipelines into multiple lines
- remove "echo" that seems to be redundant
All this should help with readability and also result in cleaner diffs
when changes are made.
This makes it easier to make customizations, for example instead of
bind -x '"\C-o\C-i": FZF_CTRL_T_COMMAND="fasd -Rl" FZF_DEFAULT_OPTS="$FZF_DEFAULT_OPTS --tiebreak=index " fzf-file-widget'
it's enough to just
bind -x '"\C-o\C-i": FZF_CTRL_T_COMMAND="fasd -Rl" fzf-file-widget --tiebreak=index'
I forgot to add the "not _fzf" check into __fzf_orig_completion, so
invoking it twice would rewrite the _fzf_orig_completion_xxx variables
and then cause an endless loop when completion is requested.

Commit d4ad4a25 slowed loading of completion.bash significantly (on my
laptop from 10 ms to 30 ms), then 54891d11 improved that (to 20 ms) but
it still stands out as the heavy part of my .bashrc.
Rewriting __fzf_orig_completion_filter to pure bash without forking to
sed/awk brings this back under 10 ms.

Fixes: 54891d11e0 ("[bash-completion] Minor optimization")
This prevents mistakes like the one fixed by the previous commit, and
also speeds bash startup a tiny bit:
before:
$ HISTFILE=/tmp/bashhist hyperfine 'bash --rcfile shell/completion.bash -i'
Benchmark #1: bash --rcfile shell/completion.bash -i
Time (mean ± σ): 22.4 ms ± 0.6 ms [User: 28.7 ms, System: 7.8 ms]
Range (min … max): 21.7 ms … 25.2 ms 123 runs

$ HISTFILE=/tmp/bashhist hyperfine 'bash --rcfile shell/completion.bash -i'

Range (min … max): 20.7 ms … 23.3 ms 132 runs
This doesn't look right:
$ complete | grep ' _.$'
complete _a
complete _v
The __fzf_orig_completion_filter invocation in _fzf_setup_completion
needs the /-F/ filter, just like all the other invocations.

Ideally, we could only use `print -sr` to update the command history.
However, the "cd" command by ALT-C is added to the history only after we
finalize the current command by pressing an additional enter key.
i.e. The cd command from ALT-C is not visible when you hit Up arrow. But
it appears once you hit enter key.
So when the current buffer is empty, we use `zle accept-line` so that
the command history is immediately updated.
Close#2200
Requires latest tmux built from source (e.g. brew install tmux --HEAD)
Examples:
# 50%/50% width and height on the center of the screen
fzf-tmux -p
# 80%/80%
fzf-tmux -p80%
# 80%/40%
fzf-tmux -p80%,40%
# Separate -w and -h
fzf-tmux -w80% -h40%
# 80%/40% at position (0, 0)
fzf-tmux -w80% -h40% -x0 -y0
You can configure key bindings and fuzzy completion to open in tmux
popup window like so:
FZF_TMUX_OPTS='-p 80%'
At the top of each zsh file options are set to their
standard values (those marked with <Z> in `man zshoptions`)
and `aliases` option is disabled.
At the bottom of the file the original options are restored.
Fix#1938
To make it easier to write more complex fzf options. Although this
does not break backward compatibility, users are encouraged to update
their code accordingly.
# Before
_fzf_complete "FZF_ARG1 FZF_ARG2..." "$@" < <(
# Print candidates
)
# After
_fzf_complete FZF_ARG1 FZF_ARG2... -- "$@" < <(
# Print candidates
)
Restore the original line when search is aborted. Add --query
"$READLINE_LINE" and fall back to the current behavior pre Bash 4.

Close#1370
Parses the history list, converts it to a NUL-delimited list of possibly
multiline entries. Adds the fzf --read0 option. Works with and without
histexpand enabled.

Make C-t more consistent pre and post Bash 4. It already kills the
command line separately before and after the insertion point. Add
set-mark and exchange-point-and-mark to restore the insertion point
after yanking back and apply the same behavior to M-c.
* CTRL-T should put extra space after pasted items
