Bash source command not working with `curl`

Question

I am trying to use source in-conjunction with curl.

However, when I run the following segment of code on my machine (Mac OS 10.13.4) it outputs the following error: read_os_name: command not found.

read_os_name.sh:

#!/bin/bash

declare -r UTILS_URL="https://raw.githubusercontent.com/nicholasadamou/bash-utils/master/utils.sh"
source <(curl -s "$UTILS_URL")

read_os_name #Should output "macos"

read_os_name() from utils.sh:

read_os_name() {

    local kernelName=""

    # - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

    kernelName="$(uname -s)"

    if [ "$kernelName" == "Darwin" ]; then
        printf "macos"
    elif [ "$kernelName" == "Linux" ] && [ -e "/etc/os-release" ] || [ -e "/usr/lib/os-release" ]; then
        local conf=""

        if test -r /etc/os-release ; then 
            conf="/etc/os-release"
        else 
            conf="/usr/lib/os-release"
        fi

        awk -F= '$1=="ID" { print $2 ;}' "$conf" | sed -e 's/^"//' -e 's/"$//'
    fi

}

@codeforester yes, `read_os_name` is inside the script being sourced. — Nicholas Adamou, May 31 '18 at 22:50
The script works fine for me on RHEL. Run your script as `bash -x ./read_os_name.sh` to see what is happening. — codeforester, May 31 '18 at 22:52
@codeforester it outputs the following: https://pastebin.com/raw/Lfsx5HQX and errors with: `read_os_name: command not found` probably because the `source` cmd isn't working for some reason. I agree, it works for me on Linux, but not on MacOS, which is my problem. — Nicholas Adamou, May 31 '18 at 22:57
Are you sure you're using `bash` on your Mac? `source` is a C-shell-ism imported into Bash — try using the original/native dot command (spelled `.`) instead of `source`. — Jonathan Leffler, May 31 '18 at 22:59
As an aside, I think it is better to clone your git repo and use the scripts directly instead of the indirect method of using `curl` to get them. — codeforester, May 31 '18 at 23:00
@codeforester `curl -s "$UTILS_URL"` runs correctly by outputting the contents of the `utils.sh` on my git repo. — Nicholas Adamou, May 31 '18 at 23:02
@JonathanLeffler I am certain I am using `bash` on my system. I have tried using the native dot command `. ` and the same problem occurs. — Nicholas Adamou, May 31 '18 at 23:03
@NicholasAdamou And you're not running `sh yourscript`, right? — that other guy, May 31 '18 at 23:04
@codeforester the whole point of using this curl method is to allow me to type in 1 line of code into a `bash` file and gain access to the functions within it without actually having the file on my system. — Nicholas Adamou, May 31 '18 at 23:05
@thatotherguy Yes, I am sure. I am running `bash read_os_name.sh`. — Nicholas Adamou, May 31 '18 at 23:06
