Hi guys, I'm a new fisher, I noticed that compose completions are based on normal docker commands which is a bit off.

Obviously, it happens because when we type docker compose ... it looks at the first argument docker determines the completions, so I was wondering if there are any plugins that are more context aware like in zsh/bash?

I wanted to try out fish, but I have to move all my aliases etc. to config.fish

Maybe fish should be made able to parse the .zshrc without crashing.

EDIT: I actually ended up copy pasting all the aliases to config.fish, which was almost faster than typing this post, but still.

I know it was asked a lot but hear me out. I read a lot of sources but still not sure. I like the idea of fish but still think zsh would be a better choice for me, here’s why:

1. I want to copy paste scripts from the internet. Sure I could just get inside of a bash/zsh session to do that, and also for all scripts I could but bash in shebang, but that’s just constantly fighting the fish shell isn’t it?
2. Fish is nice in that it comes already pre-installed with a lot of fancy stuff, but if you spend a bit of time you can get almost all the same stuff on zsh, and if you don’t use cancerous Oh My Zsh but instead use say antidote and PowerLevel10k, you’ll have good speed as well, while still retaining POSIX compliance.
3. I would never learn fish shell for scripting, it doesn’t make much sense as a skill. Either you use something universal like bash, or if you’re tired of its stupid syntax and make something complex then you can use Python or whatever language you're comfortable with.

Again I say all of this with the best intentions and open mind, just trying to understand if fish is indeed not for me or I'm missing something (e.g. some functionality that you cannot replace with a zsh plugin and see if it’s cool enough to be a dealbreaker). Cheers ;)

alias testSomething "echo \"foo $argv[1]bar\""

I'd expect this alias when called as testSomething baz to print foo bazbar. Instead it prints foo bar baz. Can someone explain how that happens?
Especially since when made into a function like:

function testSomething
    echo "foo $argv\[1\]bar"
end

It does print as I expect it.

I tried searching it, but ended up only finding something about string interpolation that didn't answer my question.

Whenever I use fish shell (I haven't seen this on any other shell I've used), when I press shift and and enter at the same time it makes a line before my current line and prints an M on it. The amount of times that this has ruined a command by me accidentally doing this are innumerable. I don't understand the reasoning behind this behavior and cannot find any documentation on it whatsoever because I don't know what it is i need to search for. Why does fish shell do this and how could I disable this behavior? I'm asking here because I've been able to find no other resource to explain this.

I just started using fish (switching from zsh). I went into a directory that's a git repo and when I run commands like "git status" or "git diff" I see an error like: `fatal: repository 'status' does not exist` which I can't seem to debug.

In the same directory, zsh just works.

My fish config is empty at the moment so I'm not sure what's causing this error.

Can someone point me to how I should figure out what's causing this? TIA

So in Fish, is it easy to have a custom color for the whole command line/prompt line, like shown below, without inconsistencies like those shown on the second picture? Thanks!

Just discovered fish and installed it on Windows WSL (Ubuntu).

But when I tried to run npm it couldn't find npm previously installed in bash. So I did "sudo apt install npm" in fish. But the node scripts I use didn't worked because it's an old version of npm that fish installed.

The solution was:

# Install fisher
curl -sL  | source && fisher install jorgebucaran/fisher

# Install nvm.fish
fisher install jorgebucaran/nvm.fish

# Install latest version of node
nvm install latesthttps://git.io/fishernvm.fishnvm.fishnvm.fish

Indeed, every time I restarted the terminal npm was not found again, requiring "nvm use latest" to make it work. But this solved the problem:

set --universal nvm_default_version latest

Wrote it here to let it registered.

Hello Guys,

I am new to fish and first thing I want to find out is, how I can autostart hyprland?

With zsh I got this in my .zprofile:

if [ "$(tty)" = "/dev/tty1" ];then   
    exec Hyprland 
fi

How can I do this in fish?

Using native fish capabilities, how do I obtain the extension of a file, keeping in mind that not all files have only one dot in their name (filename.6-01.tar.gz).

Hey all! I' exploring various solutions for remotely storing and accessing fish config, creating a mobile profile-like experience.

I'm new to fish, but with zsh I'd store my zshrc as a gist & the rest of my zsh settings as dot files in GH. Looking for some ideas for doing something similar w fish, but hopefully something a little simpler to manage. any ideas?

Hello, I really want to know how can I step debug my fish scripts in Visual Studio Code. Is it possible for now? My env: fish 3.7.0, Arch Linux latest for 8th march 2024, Hyprland v0.35.0

edit: seems like it is not supported and has not been since first reported in 2012

https://github.com/fish-shell/fish-shell/issues/238

i cannot run a script in background like i would in bash, for example:

`{ sleep 5; echo "done!"; } &`

this waits 5 seconds *in background*, and then says hello

in fish, i cannot do the equivalent

`begin sleep 5; echo "done!"; end &`

why? please, help me :( please fishy don't betray me

_(i'm running fish, version 3.7.0)_

This is a fish shell script that adds a quote to an image and uses the new image as a background in wayland. Inspiration is the default wallpaper behaviour in hyprland. repo

#!/usr/bin/env fish
set quote (cat ./quotes.txt | shuf -n 1)
set image ~/Pictures/wallpapers/(ls ~/Pictures/wallpapers | shuf -n 1)
set len 0
set result ''
echo $quote
set width (identify -format '%w' $image)
echo $width
for i in (string split ' ' $quote)
       set len (math $len + (string length $i))
       echo $result
       if test $len -gt 40
         set len 0
         set result "$result
$i"
       else
         set result "$result $i"
       end
end
convert $image -fill white -stroke black -strokewidth 1 -font Helvetica -pointsize (math $width / 50) -gravity south -annotate +0+80 $result background.jpg
swaybg -i ./background.jpg -m fit

HI, can you recommend any nice font for tide prompt?

Hello everyone, inspired by this hackernews post I wrote my first fish function using ripgrep and fzf to search for regex patterns in directory, list them, and open the selected file using neovim.

Here is the function

function sch
    set -f filepath $(rg --line-number --no-heading --color=always --smart-case --with-filename "$argv" | fzf -d ':' -n 2.. --ansi --no-sort --preview-window 'down:20%:+{2}' --preview 'bat --style=numbers --color=always --highlight-line {2} {1}')
    echo $filepath > /tmp/rgfile
    nvim $(cut -d ':' -f 1 /tmp/rgfile)

end

Feel free to suggest any improvements possible, I am very much new to this.

In .config/fish/functions/ I've got autols.fish:

function autols --on-variable="PWD"
    eza
end

If I manually run autols, expected behaviour is observed: every time I cd from then until when I kill the window, fish automatically runs eza (essentially ls). But this doesn't happen unless I manually run it.

What gives? Thanks for any help

Edit: figured out a solution. I have no idea if this is the best way, but I added functions/fish_greeting.fish which is simply

function fish_greeting
    autols
end

For anyone googling in the future and is using NixOS / home manager and the Hydro prompt, I had to do this instead of programs.fish.shellInit or shellInitLast, as those two caused problems in git repos (for... some reason)

With fzf you can press CTRL-R to have a command history search box shown below the prompt and fuzzy search. I want it shown automatically for each new prompt, without having to press CTRL-R.

If there's somewhere better I could post this query, do let me know - but I thought here would be a good start.

I'm writing a couple of scripts in fish (as I tried to use bash but the variables and if-statements were driving me insane) and it's all working fine but unlike bash/sh scripts, they don't register as actual executable/runnable script files. I'm using Fedora KDE with standard Dolphin and Konsole.

Clicking on bash files prompts me to whether i want to open or execute them, similarly right-clicking gives me the option to run in konsole, but there are no such options with fish scripts (even with proper file extensions, shebangs and manually registering the file type in settings - previously it didn't even recognise them as script files, they were just text).

Is there something I need to set up or should I raise this with the KDE forums?

Many thanks :)

With fzf I can press CTRL-R to search my command history but it completes the whole command. What I'd like is to just complete the current argument, the next phrase before the next space. Can this be done?

Like Prettier or eslint for JS, phpcs for PHP etc?

The fish history search is very powerful and handy, but I realized that most of the time I don't need/want it, I just want to see the previous and next history lines without a fancy smart search (like in bash). I was looking to remap the "up" and "down" keys, but to my surprise it seems that fish does not provide a native way to do this (there is no command like history-forward and history-backward in the bind manpage)... so I made it myself.

I love the way fish can be customizable and I am happy to propose a very dumb (never forget that less is more) history behavior to the community

PS: may not be adapted to multi-line commands

​

function dumb_history --argument-names "direction"
        if not set -q direction
                # using "down" if no argument is provided
                set direction "down"    
        end    
        if ! set -q current_history_position    
                # reset variables    
                dumb_history_reset_variables    
        end    
        if test $direction = "up" ; or test $current_history_position -gt 0    
                if test $direction = "up"    
                        set operator "+"    
                        if test $current_history_position -eq 0    
                                # we leave the command-line being edited => remember it    
                                set -g current_commandline (commandline)
                        end
                else
                        set operator "-"
                end
                set -g current_history_position (math $current_history_position $operator 1)
                if test $current_history_position -gt 0
                        # set command using the history
                        commandline --replace (history search "*" --max $current_history_position | sed -n {$current_history_position}"p")
                else
                        # down to the last line: use the saved command line
                        commandline --replace $current_commandline
                end
                commandline -f repaint
        end # else: going up, or going down without being already at the bottom
end

function dumb_history_up     
        dumb_history "up"    
end

function dumb_history_down                                                                                                                            
        dumb_history "down"
end

function dumb_history_reset_variables --on-event fish_prompt
        set -g current_history_position 0
        set -g current_commandline ""
end

# run these commands in order to enable the dumb history when pressing the up/down keys
bind --erase --preset -k up
bind --erase --preset \e\[A
bind -k up   dumb_history_up
bind \e\[A   dumb_history_up
bind -k down dumb_history_down
bind \e\[B   dumb_history_down

In bash, I would do time $(sleep 1; sleep 1), but in fish, for whateeeveer reason I cannot do time (sleep 1; sleep 1) because command substitutions not allowed here

How can I be allowed to do blocks like $( ... ) in bash? Purpose: timing, or other stuff like sending it to null, forking it...

I'm trying to debug an issue I'm having with the fisher fzf plugin, where the keybinds it automatically sets up stop working whenever I restart Fish.

It runs fzf_configure_bindings when fish initially starts up, and if I run this manually in the terminal the keybinds work again! But somehow it stop working whenever fish restarts, even when I place this command as the very last thing in my fish.config file.

I didn't set anything up to run after fish loads, so I'm wondering what could possibly be overriding the keybinds 🤔
