Try it yourself. We dont know what you like.

to me fish seemed like zsh. The differences were the highlighting and the auto-completion. I don't really see why fish highlights the first 2 letters when it only is going to show matches that have those 2 letters in them. I also found that fish's auto-completion reveals too many details that i don't care about. Why would i ever care about the size of an app when i'm running it? If you're look for a replacement for bash try zsh.

I just installed it. fish seems nice, but it feels a little bit slow. I guess it's because everything is implemented as function.
There were also some errors in the scripts:
I always got some complaint from grep and awk when doing tab-completion, but adding a simple 2>/dev/null behind the completion functions solved the problem.
Why would i ever care about the size of an app when i'm running it? If you're look for a replacement for bash try zsh.
you may change that. you got to hack /usr/share/fish/functions/__fish_describe_command.fish. but i can't figure out what you got to change.

Hello,
I've hacked up a quick syntax completion for pacman:
# Completion for pacman
# All-time options
complete -c pacman -s h -l help -d (N_ "Display syntax for given operation")
complete -c pacman -s d -l nodeps -d (N_ "Skip dependency checks")
complete -c pacman -s f -l force -d (N_ "Bypass file conflict checks")

complete -c pacman -s v -l verbose -d (N_ "Output more messages")
complete -c pacman -l config -d (N_ "Specify alternate config file") -r
complete -c pacman -l noconfirm -d (N_ "Bypass any questions")
complete -c pacman -l noprogressbar -d (N_ "Don't show progress bars when downloading")
# Sync options
set -- pacman_sync -c pacman -n "__fish_contains_opt -s S sync "
complete $pacman_sync -s c -l clean -d (N_ "Remove old packages from cache")
complete $pacman_sync -s g -l groups -d (N_ "Display packages in a group; list all groups")
complete $pacman_sync -s i -l info -d (N_ "Display information for package")
complete $pacman_sync -s l -l list -d (N_ "List all files in the specified repositories")
complete $pacman_sync -s p -l print-uris -d (N_ "Print out URIs for packages to be installed")

complete $pacman_sync -s y -l refresh -d (N_ "Refresh package list")
complete $pacman_sync -l ignore -d (N_ "Ignore given package")
set -e pacman_sync
# Remove options
set -- pacman_remove -c pacman -n "__fish_contains_opt -s R remove "
complete $pacman_remove -s c -l cascade -d (N_ "Also remove all packages that depend on these packages")
complete $pacman_remove -s k -l keep -d (N_ "Only remove database entry, leave files in place")
complete $pacman_remove -s n -l nosave -d (N_ "Don't save .pacsave files")
complete $pacman_remove -s s -l recursive -d (N_ "Remove with unneeded dependencies-reverse sync")
set -e pacman_remove
# Query options
set -- pacman_query -c pacman -n "__fish_contains_opt -s Q query "
complete $pacman_query -s e -l orphans -d (N_ "List all packages explicitly installed")
complete $pacman_query -s g -l groups -d (N_ "Display groups the package is member of")
complete $pacman_query -s i -l info -d (N_ "Display information for package")
complete $pacman_query -s l -l list -d (N_ "List all files owned by package")
complete $pacman_query -s m -l foreign -d (N_ "List packages not found in sync database")
complete $pacman_query -s o -l owns -d (N_ "Search for package that owns <filename>") -r
complete $pacman_query -s p -l file -d (N_ "Query this package (filename given on cmd. line)")
complete $pacman_query -s s -l search -d (N_ "Search for package")
set -e pacman_query
# General options
set -- pacman_mode -c pacman -n '__fish_contains_opt -s A -s F -s Q -s R -s S -s U -s V add freshen query remove sync upgrade version; if test $status = 0; false; else; true; end'
complete $pacman_mode -s A -l add -d (N_ "Add a package to the system") -r
complete $pacman_mode -s F -l freshen -d (N_ "Upgrade already installed packages")
complete $pacman_mode -s Q -l query -d (N_ "Query the package database")

complete $pacman_mode -s S -l sync -d (N_ "Synchronize packages")
complete $pacman_mode -s U -l upgrade -d (N_ "Upgrade a package") -r
complete $pacman_mode -s V -l version -d (N_ "Display version and exit.")
set -e pacman_modeThe file goes into /usr/share/fish/completions/pacman.fish. I didn't pay much attention to details and there is no completion for installed or remote packages (querying pacman for that would take too long ATM). It would be nice if the maintainer of fish in AUR include this file with the package.
Best,

The more I play with fish the more I like it. It's simpler than zsh, and autocompletion works out of the box. Besides the powerful autocompletion, it also shortens the path when it becomes long (/usr/share/fish/completions becomes /u/s/f/completions), and writes the current program running and path to the terminal title. All that without any setup.
Writing completions is also very easy, here's another one, for makepkg:
# makepkg syntax completion
complete -c makepkg -s b -l builddeps -d (N_ "Build missing dependencies from ABS")
complete -c makepkg -s B -l noccache -d (N_ "Don't use ccache")
complete -c makepkg -s c -l clean -d (N_ "Clean up leftover dirs after the build")
complete -c makepkg -s C -l cleancache -d (N_ "Remove all source files from cache dir")
complete -c makepkg -s d -l nodeps -d (N_ "Don't perform dependency checks")
complete -c makepkg -s e -l noextract -d (N_ "Don't extract source files (use src/)")
complete -c makepkg -s f -l force -d (N_ "Force build")
complete -c makepkg -s g -l genmd5 -d (N_ "Download sources and generate md5 hashes")
complete -c makepkg -s h -l help -d (N_ "Help")
complete -c makepkg -s i -l install -d (N_ "Install/upgrade package after build")
complete -c makepkg -s j -d (N_ "Set MAKEFLAGS") -r
complete -c makepkg -s m -l nocolor -d (N_ "Disable color in output messages")
complete -c makepkg -s n -l nostrip -d (N_ "Don't strip binaries and libraries")
complete -c makepkg -s o -l nobuild -d (N_ "Download and extract files only")
complete -c makepkg -s p -d (N_ "Specify file alternative to PKGBUILD") -r
complete -c makepkg -s r -l rmdeps -d (N_ "Upon build, remove dependencies installed by makepkg")
complete -c makepkg -s s -l syncdeps -d (N_ "Install missing dependencies via pacman")
complete -c makepkg -s S -l sudosync -d (N_ "Install missing dependencies via sudo pacman")
complete -c makepkg -s w -d (N_ "Specify destination directory")
complete -c makepkg -l noconfirm -d (N_ "Don't ask questions")
complete -c makepkg -l noprogressbar -d (N_ "Don't draw progress bar")Best,

fish is nice but it just isn't my thing, I just keep it with bash.
it really depends on what flavor people like.

Fish rocks! It is my thing. I just jumped ship.

To get environmental variables in fish, paste this in .config/fish/config.fish
# FISH does not accept non existing paths, clean it
set tmp_path $PATH
setenv PATH
for path in $tmp_path
setenv PATH $PATH $path ^ /dev/null
end
if status --is-login
for line in (sh --noprofile --norc -c '. /etc/profile; env')
set variable (echo $line | cut -d '=' -f 1)
set value (echo $line | cut -d '=' -f 2-)
# Convert to array
if test (echo $value | grep ":")
set value (echo $value | sed -e 's/:/\n/g')
end
if test $variable = PATH
for path in $value
setenv PATH $PATH $path ^ /dev/null
end
else
setenv $variable $value ^ /dev/null
end
end
