How to load zsh/mapfile in ZSH

I have installed zsh version 5.6.2 via brew. I am having trouble loading mapfile module.

adding zmodload zsh/mapfile mapfile gives error ~/.zshrc:15: failed to load module 'mapfile': dlopen(/usr/local/Cellar/zsh/5.6.2_1/lib/mapfile.bundle, 9): image not found

Anyone know how to debug this or a fix ?

To load the zsh/mapfile module, just run

zmodload zsh/mapfile

You can check that it's correctly loaded with:

zmodload

You should then see the following list of loaded modules:

zsh/complete
zsh/main
zsh/mapfile
zsh/parameter
zsh/zle
zsh/zutil

You can then use it, for example, such as:

# Define a file named pp with three lines
echo yay1 >> pp                                                                     
echo yay2 >> pp
echo yay3 >> pp

# Build the associative array
arr=("${(f@)mapfile[pp]}")

# Show the content
echo $arr[1]
echo $arr[2]
echo $arr[3]

For explanation about the mapfile module see ZSH Gem #22: Accessing and editing files with mapfile.

For details about the Parameter Expansion Flags see the corresponding section in the Zsh documentation.
