cloudflare.sh

Just a little script I cooked up at work for updating records in Cloudflare hosted DNS zones. In the end we did not use the script, as there is already a much better project that does this (https://github.com/danielpigott/cloudflare-cli).

I tried to use bash as a proper programming language, with correct error handing and all. And while I did succeed bash has some deficiencies that make is hard to do this:

1. Functions are not really functions, but are rather command groupings that have their own positional arguments. This is evident by the lack of return keyword, the only way to return something for a function is to use echo. This obviously is very problematic, as it limits what you can output on the screen for logging purposes.
2. The only way to assign a value from a function to a variable is to use command substitution NAME="$(echo 'Aleksandar')", command substitution gets executed in a subshell, and parent shell has no idea about the success or failure, unless you check the exit status after every variable assignment. This kinda reminded me of golang and if err != nil { return err }.

All in all, a fun little experiment I would not repeat. If you need a real programming language use one.
