MacOS ZSH version?

[thebrownjumper]

In zsh there's no builtin readarray command, however it does have a one line expression which achieves the basic syntax of readarray -t.

myarray=("${(@f)$(command)}")

Are you looking to provide a macOS version of this plugin?

Hi @thebrownjumper! Actually, I use only Linux with bash, so I do not have a possibility to develop and test this tool for Mac (although, I think zsh should be the same in Linux and Mac). Moreover, I am not a big expert in this area, so I maybe not the right person to develop this plugin for Mac. However, I would be grateful if you can make it working for Mac as well.

 brew install gawk

ps: took the shortest way out.

Just a little more context, according to https://www.gnu.org/software/gawk/manual/html_node/String-Functions.html

The array argument to match() is a gawk extension. In compatibility mode (see Command-Line Options), using a third argument is a fatal error. 

that is why i installed gawk on my M1.
