Migrating zshrc to using antigen

[orschiro]

Hi there,

By Shrikant Sharat I was advised to open an issue for my question. I discovered antigen and want to move my zshrc completely to using antigen.

I followed several introductions and now my zshrc looks as follows:

~ cat .zshrc
# Configuration largely inspired by
# http://danryan.co/using-antigen-for-zsh.html
[ -e "${HOME}/.zsh_aliases" ] && source "${HOME}/.zsh_aliases"
export PATH=$HOME/bin:/usr/local/bin:$PATH

source /usr/share/zsh/scripts/antigen/antigen.zsh 

antigen use oh-my-zsh

# bundles from oh-my-zsh
antigen bundle git
antigen bundle rupa/z
antigen bundle zsh-users/zsh-syntax-highlighting

antigen-theme zhann
antigen-apply

# keybindings
# https://wiki.archlinux.org/index.php/Zsh#Key_bindings
# create a zkbd compatible hash;
# to add other keys to this hash, see: man 5 terminfo
typeset -A key

key[Home]=${terminfo[khome]}

key[End]=${terminfo[kend]}
key[Insert]=${terminfo[kich1]}
key[Delete]=${terminfo[kdch1]}
key[Up]=${terminfo[kcuu1]}
key[Down]=${terminfo[kcud1]}
key[Left]=${terminfo[kcub1]}
key[Right]=${terminfo[kcuf1]}
key[PageUp]=${terminfo[kpp]}
key[PageDown]=${terminfo[knp]}

# setup key accordingly
[[ -n "${key[Home]}"     ]]  && bindkey  "${key[Home]}"     beginning-of-line
[[ -n "${key[End]}"      ]]  && bindkey  "${key[End]}"      end-of-line
[[ -n "${key[Insert]}"   ]]  && bindkey  "${key[Insert]}"   overwrite-mode
[[ -n "${key[Delete]}"   ]]  && bindkey  "${key[Delete]}"   delete-char
[[ -n "${key[Up]}"       ]]  && bindkey  "${key[Up]}"       up-line-or-history
[[ -n "${key[Down]}"     ]]  && bindkey  "${key[Down]}"     down-line-or-history
[[ -n "${key[Left]}"     ]]  && bindkey  "${key[Left]}"     backward-char
[[ -n "${key[Right]}"    ]]  && bindkey  "${key[Right]}"    forward-char
[[ -n "${key[PageUp]}"   ]]  && bindkey  "${key[PageUp]}"   beginning-of-buffer-or-history
[[ -n "${key[PageDown]}" ]]  && bindkey  "${key[PageDown]}" end-of-buffer-or-history

# Finally, make sure the terminal is in application mode, when zle is
# active. Only then are the values from $terminfo valid.
if (( ${+terminfo[smkx]} )) && (( ${+terminfo[rmkx]} )); then
    function zle-line-init () {
        printf '%s' "${terminfo[smkx]}"
    }
    function zle-line-finish () {
        printf '%s' "${terminfo[rmkx]}"
    }
    zle -N zle-line-init
    zle -N zle-line-finish
fi

As you can see, the whole bunch of code lines starting with the keybindings is bloating up my zshrc.

Thus, I am wondering, can this be simplified when using antigen?

Are there any plugins available that provide the same functionality to polish my zshrc?

Thanks a lot for your advice!

Antigen itself doesn't provide any shortcuts specific to help with keybinding, but perhaps there's an extension that helps with this? Sorry, I'm not aware of one.

Thank you for your response. To summarise, my current zshrc cannot be further simplified.

That's good to know as I had the feeling that I have overcomplicated my source file.
