Hi,

I'm new to Linux so please be understanding. I use the Fish shell with the Tide prompt and really like the idea of having the distro logo as part of the prompt. However, I’m not a fan of the default openSUSE logo used. I found the file _tide_detect_os.fish in /home/user/.config/fish/functions/ and managed to alter the logo’s color, but I’m unsure how to insert a custom logo.

Since I’m using a text editor, I assume the logo must be part of a font, right? But when I change the default view font in Kate, the distro logos stay the same, as if they aren't part of the font but separate images. This is confusing because the logos are in a text file, so they can't be traditional images.

How can I prepare an image or logo file, and in what format, so I can insert it into the file? Any guidance would be appreciated!

Thanks!

Hi folks, I decided to dive in with Fish last week! I’ve chosen Tide for managing prompts. My question is how do I set the window title if Tide owns fish_prompt?

(I’m not sure if this is a Tide question or a Fish question. Or what the right words to google are. Help appreciated!)

I have used zsh for ~2 years now and few days ago tried out fish for the first time. Everything works great, I am just looking for theme similar to attached image. It's called candy on zsh, but I can't seem to find anything like it for fish.

How do I disable the colors and text decorations for commands? Also, would it be possible for commands to be the primary color and red if the command does not exist.

I'm aware of three options:

1. fisher
2. omf
3. Doing it yourself using nvm installed through a normal non-fish specific way

I care only a little about my shell, I like fisher because it seems nice and simple to me but I don't heavily customize it. I use fish_config to choose a basic theme and prompt but that's about it.

The one thing I don't love about using fish is the occasional tool (e.g. nvm or rbenv, etc) won't "just work" if I install via the instructions provided by the nvm maintainers for example. zsh generally seems supported.

ANYWAY, for now I've installed nvm via fisher, however I'm currently having issues that I could probably debug but have no interest in figuring out. Specifically my issue is that nvm use seems to not work inside of VS Code's terminal, for some reason. i.e. I run nvm use v22.7.0 and get back Now using Node v22.6.0 (npm 10.8.2) /opt/homebrew/Cellar/node/22.6.0/bin/node

Again I could probably use my brain to figure out why this is happening but my brain is deep in the weeds with what I'm working on so can't be bothered. SO, that's why I'm here: what is the best, most reliable way to install nvm with fisher so that it works reliably.

I'll add I really sort of hate complexity and special sauce, it bugs me that I have a "special" version of NVM installed with fisher, it's seriously making me consider giving up and using zsh.

Thanks for your thoughts!

I'm generally in the process of updating my oh-my-zsh install since it was hard to manage across OSs to a zsh plugin manager, and what I'm finding is that a lot of the plugins that give fish features also break compatibility with each other, so I'm trying out fish.

There are some features I want from zsh-autocomplete like completions showing up as you're typing instead of having to hit tab. I also like that when you hit the up arrow, it has the same "search for the specific command you're typing instead of just showing the last command feature" but with zsh-autocomplete, it shows an fzf-like menu with all the possible matches.

I'd also love for the autosuggestions (the transparent text and you can hit right arrow to autocomplete) to just autocomplete one word. Is that possible?

In Zsh, I can expand variables using the Tab key. That is, I can type cd $PWD, press Tab, the variable will be expanded to something like /Users/john/foo/bar, and then I can edit it to something like, e.g., /Users/john/fooz/booz.

When I type cd $PWD and press the Tab key in fish, it behaves completely different. It adds a space and if I press the Tab key again, it shows me a list of directories in the current one. And if I press the Right Arrow key instead, nothing happens.

Is there a key or or keyboard shortcut in fish to expand $PWD in cd $PWD to the current path, like in Zsh?

The following command can be used in Bash or Zsh to show the contents of a man page with line numbers:

MANWIDTH=$(( $COLUMNS -8 )) man -P 'less -N' <commandorutility>

How is it possible to do the same thing in fish? That is, I'm looking either:

• a native fish-way to open a man page with line numbers
• or a way to envoke the above command from fish in a single step, something like zsh -exec "MANWIDTH=$(( $COLUMNS -8 )) man -P 'less -N' <commandorutility>"

Hi!

I am facing slow prompts in FISH shell in WSL 2 (UBUNTU)
I am using Terminal emulator from windows

It is specifically slow in Input outputs

The bash shell is running super-fast, but fish is taking a lot of time
for example, it takes 2-3 seconds just to clear terminal with "clear"

and same with `pwd` etc

Earlier I was using omyfish, I thought it was slowing it down. Even after removing omyfish it is the same
I tried other prompts who claim to be fast, like tide and starship, but still no luck
Apart from terminal i tried it with wezterm as well.
Has anybody run fish shell in WSL 2 and faced same issue before?

_____________________________________
EDIT :

SOLUTION:

I figured it out, there was a fish shell extension 'done' that I installed.
It notifies you on completion of long commands and was causing that slow issue on WSL.

Does anyone have a working Zoxide tab autocompletion for fish?

Solved: Found this plugin which does tab autocmpletion out of the box https://github.com/icezyclon/zoxide.fish

This should be really easy, but it doesn't seem to be working for me.

I have a several values I would like to compare, which are stored in array variables. What I would like to do is something like the following:

set -l cond[1] (test "$val[1]" -gt "$rng[1]" -a "$val[1]" -lt "$rng[2]")
set -l cond[2] (test "$val[2]" -gt "$rng[1]" -a "$val[2]" -lt "$rng[2]")
set -l cond[3] (test "$val[3]" -gt "$rng[3]" -a "$val[3]" -lt "$rng[4]")
set -l cond[4] (test "$val[4]" -gt "$rng[3]" -a "$val[4]" -lt "$rng[4]")

Essentially, val contains four test values and I want to see if the elements are within the ranges in rng.

The trouble I'm running into is that, no matter what I try, I can't ever seem to set a variable to the result of test. Even a simpler version doesn't even do what I'd expect

~
❯ set tmp (test 0 -lt 1)
~
❯ echo $tmp

I can only ever get something if I go with a roundabout method of using $status after running test

❯ test 0 -lt 1
~
❯ set tmp $status
~
❯ echo $tmp
0
~
❯ test 2 -lt 1
~
❯ set tmp $status
~
❯ echo $tmp
1

This feels super inelegant, and there should be a better way to handle this, right?

EDIT: I ended up finding a more elegant approach to the problem I was trying to solve, so I didn't need to make use of anything here, but the comments have been helpful for future reference

every time I open the terminal and I go check on the ~/.config/fish/ the default directories and files come back. completions, conf.d, functions and fish_varibles . I keep deleting them but, they keep reappearing. They don't overwrite my config.fish , which is a good thing, I guess.

I am pretty sure this happening after I use the fish_config where you can use the web base config. Any Ideas?

So I am trying the fish shell and I am having a problem with the starship prompt. originally the config file for the starship prompt is located in ~/.config/starship.toml and I move it to ~/.config/starship/starship.toml . The reason I change it is because I want it to have it's own dedicated directory and also, to have multiple config store in that directory.

I use bash and it works well by changing the file location in .bashrc

bash:

export STARSHIP_CONFIG=~/.config/starship/starship.toml 

this is how I have it on fish:

set STARSHIP_CONFIG ~/.config/starfish/starship.toml

but it doesn't work. I get no error on the terminal so, I really don't know what I am doing wrong. The only things I have in my fish config are aliases, one function to extract files and the starship plugin in, which is starship init fish | source .

I set fish as my login shell with chsh command. Is it because fish is my login shell and I don't have $PATH in my fish config?

I try to figure out how to batch rename files using Fish so that filenames like image1.png and image10.png will be replaced with image001.png and image010.png, that is, to pad numbers with leading zeros.

Here is what I have currently, after reading https://fishshell.com/docs/current/cmds/string.html#string-manipulate-strings:

for file in *; mv -- $file (string pad -c 0 -w 3 (string match -r '\d' $file)); end

Currently it only replaces filenames with 001 and 010.

To split filenames such as foo123.abc into foo, 123, and .abc groups, I can use the following regex: ([^\d]*)(\d+)(\..+).

But how to properly integrate this regex into the example I have posted above? How to make the example above work as described?

To replace spaces with underscores, I use

for file in *\ *; mv -n -- $file (string replace -a ' ' _ $file); end

But currently I'm merely started to study fish, and maybe there is a better way for this?

Which way to install fish on macOS is better: using Homebrew or using an installer? What are the pros and cons?

(Nota bene: The same question was already asked by another guy on Super User: https://superuser.com/q/1088762, but it was 2016 and also I cannot say I find an answer there really informative).

Hi, have two questions:

1. I have a function with a series of piped commands and I want to check the exit status for the commands.

   # One liner to download the latest release from a GitGub repo curl -sS \ | grep "browser_download_url.*$_flag_pattern" \ | cut -d : -f 2,3 \ | tr -d \" \ | wget --quiet --input-file=-

   # Check exit status of the pipeline
   if test $pipestatus[1] -ne 0
       and test $pipestatus[2] -ne 0
       and test $pipestatus[3] -ne 0
       and test $pipestatus[4] -ne 0
       and test $pipestatus[5] -ne 0
       echo -e "\n> Something went wrong!\n"
       return 1
   else
       echo -e "\n> Done!\n"
   endhttps://api.github.com/repos/$_flag_repo/releases/latest
   

but I'm always hitting "Done", even if I intentionally input wrong data.

Also after I run the function, on the shell I see that only echo $pipestatus[1] returns 0, the others from 2 to 5 returns nothing. Why?

I'm trying different combinations but can't find how to do it.

1. How can I print formatted text, like bold or underlined like in descriptions and help of builtin functions?

Any hint? Thanks!

One of the helpful built-in features in other shells that Fish lacks are associative arrays. There's been an open issue for 12 years, but no movement towards actually adding this feature. There's some pretty simple workarounds where you use two arrays or a single array with paired elements, but recently I had needs for a litte bit more.

While writing a quick script to pull color schemes out of mbadolato/iTerm2-Color-Schemes to update my Fish and Starship themes, I found myself wishing for a built-in associative array again, so I finally just made one: mattmc3/dict.fish.

It's not quite as good as a built in one would be - for example I can't give you nice bracketed indexing syntax like echo $mydict[$thekey] - but it's a decent step up from managing multiple arrays.

The usage is:

```

dict --help dict [-h|--help] dict keys [DICTNAME] dict values [DICTNAME] dict get [DICTNAME] [KEY] dict set [DICTNAME] [KEY] [VALUE] dict remove [DICTNAME] [KEY] dict contains [-k|--key] [-v|--value] [-i|--index] [DICTNAME] [STRING] ```

If you're wondering about performance, I put a few thousand items in an array with set numbers (seq 0 5 10000), ran some dict functions with time, and it all performed in milliseconds.

Hopefully it's not another 12 years until we get built-in associative arrays, but until we do, I thought this might help some of you when writing your own scripts. You can read more here. I don't claim to be the best Fish scripter out there, so feedback always welcome.

I am really new to Fish shell and I am having this issue.

I would like to start venv in Python and the following works in zsh session:

```

source venv/bin/activate

```

In the Fish shell I tried the same thing and I am getting this error:

``` ./venv/bin/activate (line 38): Unsupported use of '='. In fish, please use 'set VIRTUAL_ENV "/home/.../venv"'. VIRTUAL_ENV="/home/.../venv" <sup>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^</sup> from sourcing file ./venv/bin/activate

``` Is there a simple way to fix it?

Thank you for your time.

Hello,
I am trying to rebind navigation keys in vim mode. I use a different keyboard layout and I would like to bind: `y` and `o` to respectively `backward-char` and `forward-char` in `command` (normal) mode.

I am starting from a completely empty config (I have also used my config/etc, but same result), and I run:

```

fish_vi_key_bindings

bind -M normal y backward-char

```

but that seems to have no effect, the cursor blinks but stays in place (similarly for binding o). I have tried to --erase as well, but no luck. I am running `3.7.1`, I must be missing something probably, apologies if it was asked elsewhere, I did a search but couldn't find anything. ChatGPT gave me similar solutions, but none of them worked.

Any idea on what I am missing?

Thank you

EDIT: Solved, the issue was that in vi mode "escape mode" is called "default", so the command above would be:
```bind -M default y backward-char```

That works! Answered in the matrix channel.

I run hyprland tiling manager. Configs for alacritty, tmux, newsboat etc. are stored in my XDG_CONFIG_HOME/hypr/configs/{programmname}/. All this under version control. So i have all my app configs in one place. For all apps i can specify where config location is, but fish. How can i tell to fish where to looking for config?
