fib example broken

[candera]

When I run ./fib.gk in the current version, it prints

#<function:48>

I'm on cygwin, and bash --version reports

bash --version

Umm. fib is still broken. Am I missing something?

[alandipert]

If you're seeing the exact same problem still, you might be missing something and should pull again. If you're seeing a different flavor of broken, it might be related to the fact that you're on cygwin - you might be the first.

Works now. Thought I had pulled already, but I guess not! Thanks!

When Craig reported this, I couldn't run:

./gherkin -l fib.gk

After the change, this runs for me.

However, the original problem still fails to run for me:

./fib.gk
./fib.gk: line 3: syntax error near unexpected token `lst'
./fib.gk: line 3: `  (fn (lst & more)'

I'm getting the same thing under OS X: ./fib.gk gives a syntax error. Works under cygwin.

[alandipert]

I think this is related to the difference in shebang handling between OS X and Linux, but I'm not sure what the best way to proceed is.

In a nutshell, OS X appears to be passing the script contents (instead of the script path) to gherkin, and bash is trying to interpret the Lisp code.

[candera]

One hack might be to check the first two characters of input and see if they're a shebang, and self-call with the canonical form.

I thought I pushed it already, but I guess not. So I would like to make a change so that gherkin doesn't need -l for the shebang line (/usr/bin/env behaves differently on different platforms with regard to dash arguments). In other words, the default is to treat positional arguments as files to run. I think that would make at least one case of shebangs less problematic. Sound reasonable?

[alandipert]

@kanaka :+1: In the meantime re: the general weirdness of shebang, I propose we create an examples/ directory and add a "Running the Examples" section of the readme that demonstrates executing fib.gk and other examples via ./gherkin <examples/example.gk>.

At least then newcomers on most platforms will have a good tire-kicking experience.
