I really like fzf when I use it, but it's difficult to actually use it. For example, I don't want to have to type vim $(fzf) every time I want to fuzzy find for a file. Ideally, I'd like to be able to just type ctrl-E to enter fzf and start editing the file after selecting it by pressing enter.
I don't know what keys are being pressed to accomplish what's done in the video on the github page (https://github.com/junegunn/fzf). Pressing tab just does normal auto-completion (and I don't want to do the ** style autocompletion. I want to enter fzf-tmux and have it paste the result into my command)
Can anyone help me?
The install script of fzf will setup such key bindings for you, CTRL-T, CTRL-R, and ALT-C. Refer to the the project home page for the details. The code for the key bindings can be found here.
If you do not like the default ones fzf provides, you can try writing your own.
# A simple widget for dictionary words
fzf-dict-widget() {
LBUFFER="$LBUFFER$(cat /usr/share/dict/words | fzf-tmux -m | paste -sd" " -) "
zle reset-prompt
}
bindkey '^E' fzf-dict-widget
zle -N fzf-dict-widget

I want to set vi in editing mode in zsh (I am using oh-my-zsh) at start automatically when I open my shell, so at the beginning of my .zshrc I have tried the following code:
set -o vi
or
bindkey -v
but when pressing enter in the shell I cannot enter the vi mode.
If I tried one of the two commands in the shell, it works.
Basically I want zsh to start in vi edit mode.
Any ideas how to solve this problem?
bindkey -v is enough to enable vi mode in ZSH. If you are worried the setting will be overwritten by another plugin, put the setting at the bottom of your ~/.zshrc.
After vi mode is enabled, you enter the "insert" mode by default. To enter "normal" mode, use Esc. And i or a to switch back to "insert" mode.
BTW, softmoth/zsh-vim-mode is the most powerful vim mode plugin I've ever used in ZSH.
Using bindkey -v may take over functionality such as history search with control+R and control+S. To restore that particular behavior, add the following lines after bindkey -v:
bindkey ^R history-incremental-search-backward
bindkey ^S history-incremental-search-forward
Other bindings can be found in the ZSH manual Standard Widgets section.
If you are using https://ohmyz.sh/ you can add vi-mode to the list of plugins in ~/.zshrc:
plugins=(git vi-mode)
If you don't mind to use a plugin for vi mode in zsh, here is a better choice for you to quickly reach it.
zsh-vi-mode: A better and friendly vi(vim) mode plugin for ZSH.
After adding this plugin, then you can input with vi-mode like this:
Features
Cursor movement (Navigation).
Insert & Replace (Insert mode).
Text Objects.
Searching text.
Undo, Redo, Cut, Copy, Paste, and Delete.
Surrounds (Add, Replace, Delete, and Move Around).
Switch keywords (Increase/Decrease Number, Boolean, etc. In progress).

I discovered this little navigation trick the other day, which allows me to trigger menu completions by number when I enter 'cd -'
~ cd -
0 -- ~/home
1 -- ~/home/stuff
2 -- ~/downloads
3 -- ~/wallpaper
Shell scripting syntax still reads like a foreign language to me, but to get this functionality my directory stack history is piped into the function below.
DIRSTACKSIZE=9
DIRSTACKFILE=~/.zdirs
if [[ -f $DIRSTACKFILE ]] && [[ $#dirstack -eq 0 ]];
then dirstack=( ${(f)"$(< $DIRSTACKFILE)"} )
[[ -d $dirstack[1] ]] && cd $dirstack[1] && cd $OLDPWD
fi
chpwd() {
print -l $PWD ${(u)dirstack} >$DIRSTACKFILE
}
The magical part is being able to choose from the list by number, but I have come to learn that this is probably
because the functionality for navigation by number is baked in to the 'cd -' command. Still, I'd like to use this everywhere.
Any tips writing a wrapper function (or something like that, I guess) for the completion menu that pipes in completions from the menu when it is triggered
and displays them in a numbered list where those numbers select the corresponding element?
I've gotten started reading the manual and what not, but everything remains rather opaque. Thanks!
First off, the code snippet you show has nothing to do with completion. Instead, what it does is to record the directory stack to a file in order to preserve it between zsh sessions. (Personally, I'm not even sure this is a good idea.)
A good place to start investigating zsh completions is the _complete_help ZLE widget. This is bound by default to ^Xh in zsh's viins (vi insert) keyboard map, but is unbound by default in the emacs keymap. If you want to use it in the emacs keymap (the default for many people), you have to bind it:
bindkey -M emacs "^Xh" _complete_help
Now you can type cd - (or cd +) and follow it by CTRL-Xh instead of TAB. You should see the following output:
tags in context :completion::complete:cd::
directory-stack (_directory_stack _cd)
(At this point I'll admit we're getting close to the limits of my knowledge of the zsh completion system.)
Now you can see the completer functions for the directory-stack tag in this particular context. The one you're probably interested in is _directory_stack, and you can see the content of that function with:
functions _directory_stack
…which is where those leading numbers are actually generated.
Arguably it's possible to write similar completion functions for other completion contexts, and apply the using zstyle. However, this is non-trivial completion magic, and beyond anything I have attempted
after installing prezto when I press CTRL - RIGHTARROW I can see these characters
source python;5C;5C;5C;5C
Whereas emacs key bindings like ALT- f work fine.
I just want my default keybindings where I can navigate using CTRL keys.
My efforts:
Raised a issue on github + browsed other similar issues as well.
Couldnt figure out how their solution would help my case.
Tried setting zstyle ':prezto:module:editor' key-bindings '' but it did not
work.
I have also checked modeles/editor/init.zsh but the script is
too long n I dont wanna make random changes and later keep
maintaining those.
Can anyone suggest a way so that my keybindings remain "UNCHANGED" even after .zpreztorc is loaded ?
If you're using the prezto editor module, it will override your key bindings. If you have it set to emacs mode with
zstyle ':prezto:module:editor' key-bindings 'emacs'
you will need to add your key bindings to that named keymap. You can do that with
bindkey -M emacs '^[[1;5C' forward-word
bindkey -M emacs '^[[1;5D' backward-word
This will need to be run after the editor module is loaded. You can do that by adding it to the bottom of your .zshrc file. I use the vi keymap, so I need to add the key bindings to both the viins and vicmd keymaps.
for keymap in 'emacs' 'viins' 'vicmd'; do
# [Ctrl-RightArrow] - move forward one word
bindkey -M $keymap '^[[1;5C' forward-word
# [Ctrl-LeftArrow] - move backward one word
bindkey -M $keymap '^[[1;5D' backward-word
done
unset keymap
When I search in, for example, man ls while in a tmux session, the search strings don't appear highlighted - the page jumps down so that the search string is on the top line of the buffer, as expected, but it's not highlighted.
Doing the same thing in the same shell while not in a tmux session results in highlighted search strings.
I have no idea where to start looking to solve this. Any hints are appreciated.
Based on Less Colors For Man Pages by Gen2ly, here is my man page and how to do it:

How to
(optional) I'm using Tomorrow theme for Konsole/Yakuake ;
Edit your ~/.bashrc ~/.zshrc, etc. to add :
# Colored man pages: http://linuxtidbits.wordpress.com/2009/03/23/less-colors-for-man-pages/
# Less Colors for Man Pages
export LESS_TERMCAP_mb=$'\E[01;31m' # begin blinking
export LESS_TERMCAP_md=$'\E[01;38;5;74m' # begin bold
export LESS_TERMCAP_me=$'\E[0m' # end mode

export LESS_TERMCAP_so=$'\E[38;5;016m\E[48;5;220m' # begin standout-mode - info box
export LESS_TERMCAP_ue=$'\E[0m' # end underline
export LESS_TERMCAP_us=$'\E[04;38;5;146m' # begin underline
Reload your config and try a man page search :

Fixed it. The problem is to do with the way that the screen $TERM handles italics. From the tmux FAQ:
vim displays reverse video instead of italics, while less displays italics
(or just regular text) instead of reverse. What's wrong?
This matches my problem exactly. The $PAGER used by man is less by default - basically, man uses less to show the contents of the manual pages. In my case, less wasn't highlighting text, just showing regular text.
The reason for this happening:
Screen's terminfo description lacks italics mode and has standout mode in its
place, but using the same escape sequence that urxvt uses for italics. This
means applications (like vim) looking for italics will not find it and might
turn to reverse in its place, while applications (like less) asking for
standout will end up with italics instead of reverse.
The solution is to make a new terminfo file for tmux, which lets it know that italics are supported. The solution's outlined in the (at time of writing) very, very bottom of the tmux FAQ.
After creating the new terminfo file, in tmux: C-b :source-file /absolute/path/to/.tmux.conf (from this SuperUser question) - this should make tmux reload the .tmux.conf file. However, this didn't work for me, and the changes only applied after restarting the tmux server (close all tmux sessions, then re-open them).
This thread is a few years old but is still the one that comes up as the best search result, so I'm answering with what finally worked for me. This is based off of tmux FAQ.
...but the instructions aren't completely clear on when or where to substitute the -256color string. I use gnome-terminal (v 3.16.2) with tmux, and this worked for me:
$ mkdir $HOME/.terminfo/
$ screen_terminfo="screen-256color"
$ infocmp "$screen_terminfo" | sed \
-e 's/^screen[^|]*|[^,]*,/screen-256color|screen with italics support,/' \
-e 's/%?%p1%t;3%/%?%p1%t;7%/' \
-e 's/smso=[^,]*,/smso=\\E[7m,/' \
-e 's/rmso=[^,]*,/rmso=\\E[27m,/' \
-e '$s/$/ sitm=\\E[3m, ritm=\\E[23m,/' > /tmp/screen.terminfo
$ tic /tmp/screen.terminfo
And tell tmux to use it in ~/.tmux.conf:
set -g default-terminal "screen-256color"
Note: I tried it once without the -256color and since that didn't work (still seeing italics instead of highlighting), I had to delete everything under the .terminfo dir (another dir called 's') before the infocmp would work.
I'm wondering if it's possible to write a zsh script that will write a command to the prompt but NOT execute it, i.e. leave it there for me to edit and then execute when I'm ready. I can do something like this with keybindings by leaving off the final '\C-m'. eg:
bindkey -s "\e[1;3C" "howdy!"
... I press Alt+RightArrow and the text "howdy!" is printed at the prompt and just left there.
I can also do something like what I want by writing my command to the history file and then recalling it with the up arrow. I've tried 'echo -n sometext' but it doesn't work.
Can I write a script that would exit leaving (say) " howdy! " on the command line? In actual fact I want the script to build up a complex command based on several things, but I want the script to leave it on the CLI for final editing, so automatic execution must be prevented.
Thanks in advance.
Turns out the answer is simple:
print -z $string-to-print
If you mean a zsh function and not an external script, you can write a zle (short for zsh line editor) widget and bind it to some key.
# define to function to use
hello () {
BUFFER=hello
zle end-of-line
}
# create a zle widget, which will invoke the function.
zle -N hello
# bindkey Alt-a to that widget
bindkey "\ea" hello
