Document dependency on awk

[betaprior]

For some reason awk wasn't installed on a machine, and I spent a while trying to figure out why tpm wasn't doing anything.

Yes, tpm depends on the system running an awk implementation to parse plugins. It is referenced in the following functions, which are both present in the scripts/helpers/plugin_functions.sh file:

# return files sourced from tmux config files
_sourced_files() {
        _tmux_conf_contents |
                awk '/^[ \t]*source(-file)? +/ { gsub(/'\''/,""); gsub(/'\"'/,""); print $2 }'
}

tpm_plugins_list_helper() {
        # lists plugins from @tpm_plugins option
        echo "$(tmux start-server\; show-option -gqv "$tpm_plugins_variable_name")"

        # read set -g @plugin "tmux-plugins/tmux-example-plugin" entries
        _tmux_conf_contents "full" |
                awk '/^[ \t]*set(-option)? +-g +@plugin/ { gsub(/'\''/,""); gsub(/'\"'/,""); print $4 }'
}

Since awk is not part of bash, it - as well as possibly the coreutils binaries (echo, cat, etc.) - should be listed as a hard dependency.

Perhaps someone could work some magic and write a regex parser in bash. :smiley:
