> there isn't really an entry point in murex scripts

I have a nice trick in NGS for that. Under the idea that "small scripts should not suffer", script is running top to bottom without "entry point". However, if the script has defined main() function, it is invoked (with command line arguments passed).

Example - https://github.com/ngs-lang/nsd/blob/afe0cad5e506ec4ee2fa924...

> `args` still contains more boilerplate code than I'm happy with

Is there anything preventing you to have exactly the same functionality but with syntactic sugar that it looks like parameters declaration? (Just to be clear, keeping all the ARGV machinery).

Something like (assuming local variables are supported; if not, it could still be $args[Flags] etc):

  function hippo(name:str, hungry:bool) {

Doing DevOps today? 99% either abuse bash or abuse a general purpose programming language.

bash does not meet any modern expectations from a programming language: syntax, error handling, data structures

General purpose languages such as Python, Ruby, etc are not domain specific enough to have the desired facilities.

Here is small example of straightforward solution to a small problem: list all CloudFormation stacks that are managed by the given CodePipeline.

https://github.com/ngs-lang/nsd/blob/02d66abb844b7dd6077b9976e3a03659cf4b3660/aws/codepipeline/pipeline-stacks.ngs

The script is at https://github.com/ngs-lang/nsd/blob/master/aws/cloudformation/delete-stack.ngs

I think an extensible shell like oh shell would be something I would prefer. Though it should not need closures on heap to extend (which is ridolous slow on arithmetic) and generate the data types at compilation time.

> Is there a reason we aren’t using a shell with a proper programming language for scripting?

Mostly because the people who want to introduce a "programming language" into the shell don't prioritize being a shell.

Check out the "Oh" shell for contrast. This is what a programming language looks like when you force it to conform to being a shell first priority.

This is "Scheme-like" but has FEXPRs so things can be redefined and evaluation can be controlled.

I love chatting about Kernel :D Here's my most recent post: https://lobste.rs/s/d0hogq/problem_with_macros#c_nozcrm

Thanks for showing me Oh! It really has f-exprs?! I didn't immediately see it in https://github.com/michaelmacinnis/oh/blob/main/doc/manual.m...
