Have I told you about fzf?

[M. Eerie]

Now that we know btop, meet fzf



See some samples of what can it do for us...


'Fuzzy activate module'

Code: Select all

activate $(find $PORTDIR/ -iname '*.xzm' | fzf)

Fuzzy install package (alias pacfinder)

Code: Select all

alias pacfinder='pacman -Slq | fzf --multi --preview '\''pacman -Si {1}'\'' | xargs -ro sudo pacman -S'

The fzf I made out of fzf-0.17.0-x86_64-1_slonly.txz looks nothing like your screen shot:

When I select a file, fzf just prints the file name.

Is fzf-0.17.0-x86_64-1_slonly.txz not the fzf you meant?

Or is there a trick in starting it that I miss?

[M. Eerie]

When I select a file, fzf just prints the file name.

After all, fzf is a finder...

You can do things like:

Code: Select all

xdg-open $(fzf)

in your $HOME, then start typing some video name, then hit return, then watch it (as xdg-open relies on your system mimetypes). Pretty fast if you set a terminal tab or attach a tmux session.

Also, as I showed above, you can activate a module following the same approach.

Code: Select all

activate $(find $PORTDIR/ -iname '*.xzm' | fzf)

Or if using nemesis, query the database to see package info then hit return, and selected package will be installed at your will. Maybe you can easily create a wrapper to build slack packages from there.

There's even a fuzzy youtuber

Here is a tutorial.


Regarding the color scheme (if this is what matters), this snippet (borrowed from fzfx) may put you on track. Set your FZF_DEFAULT_OPTS in your .bashrc and change it to suit your taste. (I don't know if the version is relevant here, but slackware seems to be in 0.17 while the Archlinux one I'm using on Nemesis is 0.27 by now.

Code: Select all

# DEFAULTS
# f1 opens with xdg-open, f2 opens with text editor, f3 copy path to console clipboard,
# f4 echoes path to stdout, alt+shift+d move file to trash.
defaultBind="\
f1:execute-silent(xdg-open {} 2>/dev/null)+cancel,\
f2:execute($editor {})+cancel,\
f3:execute-silent(xclip <<< {})+cancel,\
f4:accept,\
enter:execute(echo $searchPath/{})+abort"
defaultHeader="f1 → default, f2 → editor, f3 → clipboard, f4 → terminal, alt+shift+d → delete"

if [ "$(command -v bat)" ]; then
    defaultPreview="bat --style=numbers --color=always --line-range :500 {}"
else
    defaultPreview="cat {}"
fi

defaultOpts="--preview-window=right:50%:wrap"

defaultOpts="--preview-window=right:50%:wrap"

#defaultColors="
#dark,\
#bg+:#373e47,\

Thanks I check out.

Still, how do I get it to look like the screenshot you provided?

I presume https://www.youtube.com/watch?v=tB-AgxzBmH8 might explain it.

[M. Eerie]

how do I get it to look like the screenshot you provided?

I'm just using a xfce4-terminal drop-down:

Code: Select all

xfce4-terminal --drop-down --hide-borders --hide-menubar --hide-scrollbar --geometry=80x25+400+150 -I=org.xfce.terminal-settings --active-tab -T 'System Monitor' -x btop

The other tabs, I had to open manually. This is not working for me: (Pretty sure escape sequences involved)

Code: Select all

xfce4-terminal --drop-down --hide-borders --hide-menubar --hide-scrollbar --geometry=80x25+400+150 -I=org.xfce.terminal-settings --active-tab -T 'System Monitor' -x btop --tab -T 'fuzzy activate' -e activate "$(find $PORTDIR -iname '*.xzm' | fzf)"

[M. Eerie]

The other tabs, I had to open manually.

Got it working:

Inserted as a function into .bashrc

Code: Select all

function fuzzyactivate() { activate $(find "$PORTDIR"/ -name "*.xzm" | fzf --multi ); }; export -f fuzzyactivate

Then attach this to F12 keyboard shortcut:

Code: Select all

xfce4-terminal --drop-down --hide-borders --hide-menubar --hide-scrollbar --geometry=80x25+400+150 -I=org.xfce.terminal-settings --active-tab -T 'System Monitor' -e btop --tab -T 'fuzzyactivate' -x bash -ic fuzzyactivate

More than one module can be activated by selecting via TAB key, (i.e. start typing firef then hit TAB then select another module, hit TAB again then RETURN)

However the tab closes as the function ends

This could be a great resource of fzf use cases.

Nice find M. Eerie. Oneliners are one of my favourites when it comes to using the terminal.

Added in 2 minutes 14 seconds:

requirements: zsh is your shell

oh well, probably there is a need to convert to bash, then.

@M. Eerie: Do you use zsh?

Added in 16 minutes 14 seconds:
After looking into https://raw.githubusercontent.com/majam ... liners.txt (that's the raw text the reddit refers to) I only found a mere two instances where fzf is found:

{{{sh
SOURCE=$(pactl list | grep -A2 'Source #' | grep 'Name: ' | cut -d" " -f2 | fzf --prompt="Select source >")
SINK=$(pactl list | grep -A2 'Sink #' | grep 'Name: ' | cut -d" " -f2 | fzf --prompt="Select sink >")
PULSE_SOURCE="$SOURCE" PULSE_SINK="$SINK" ffplay "https://holiday.stream.publicradio.org/holiday_yc.aac"
}}}

(highlighting by me)

What am I missing?

[M. Eerie]

What am I missing?

From the original link:

"These are (mostly) oneliner commands that I've collected over a year or so. The lines that start with (*) are oneliners (grep them, or whatever, and pipe to fzf, for example)."

I guess the OP suggest to use a combo of his oneliners collection with fzf where appropiate. Not all examples will turn into fzf targets, but I think the resource is worthwhile.

There is a prettier .html version contributed by another user as well.
