zplugin ice as"program" atclone"rm -f src/auto/config.cache; ./configure" \
    atpull"%atclone" make pick"src/vim"
zplugin light vim/vim
  • as"program" – add file selected by pick'' to $PATH, do not source it,
  • atclone"…" – execute code after downloading,
  • atpull"%atclone" – execute the same code atclone'' is given, but after successful update,
  • make – run make after atclone'' and atpull'' (note: make'!' will execute before them),
  • pick"src/vim" – set executable flag on src/vim, hint that src/ should be added to $PATH.

The same but with installation (i.e. make install is being run) under $ZPFX (~/.zplugin/polaris by default):

zplugin ice as"program" atclone"rm -f src/auto/config.cache; \
    ./configure --prefix=$ZPFX" atpull"%atclone" \
    make"all install" pick"$ZPFX/bin/vim"
zplugin light vim/vim
  • as"program" – as above,
  • atclone"…" – as above plus pass --prefix=$ZPFX to ./configure, to set the installation directory,
  • atpull"%atclone" – as above,
  • make – as above, but also run the install target,
  • pick"src/vim" – as above, but for different path ($ZPFX/bin/vim).
zplugin ice as"program" make'!' atclone'./direnv hook zsh > zhook.zsh' \
    atpull'%atclone' src"zhook.zsh"
zplugin light direnv/direnv
  • make'!' – execute make before atclone'' and before atpull'' (see make above),
  • src"zhook.zsh" – source file zhook.zsh.

In general, Direnv works by hooking up to Zsh. The code that does this is provided by program direnv (built by make''). Above atclone'' puts this code into file zhook.zsh, src'' sources it. This way direnv hook zsh is executed only on clone and update, and Zsh starts faster.
