Hello, are you running this on bash 4?

[haroldcarr]

I am on a mac 10.15.7

When I first tried flk, that error is what I got.

I was picking up /bin/bash

/bin/bash --version
GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin19)

So I did

brew install bash
bash --version
GNU bash, version 5.1.4(1)-release (x86_64-apple-darwin19.6.0)

then flk worked

[chr15m]

Thanks for the detail.

[haroldcarr]

I'm curious, why closed? Is it fixed?

[chr15m]

It is not a bug. You said you were using bash 3.2.57 when you saw the error, but that version of bash is not supported.

[chr15m]

@haroldcarr wait a second - did uou see the (env) error on bash 5?

[haroldcarr]

The bash 3.2.57 error had to do with declare -A

The env -0 IS a bug. -0 is not supported on FreeBSD and Mac OS.

THis bug should be reopened.

[chr15m]

👍 cool thank you for the detail.

FYI - this can be worked around by conda install coreutils.

Out of curiosity, do you have an idea of how difficult it would be to backport this project to bash for macos? It seems like the main challenge is usage of associative arrays.

[chr15m]

@joelmccracken It's conceivable but beyond my time and abilities. Here's an associative array implementation that works in Bash 3 for anybody who would like to tackle this in future: https://gist.github.com/chr15m/fb257ae8bb9774245b0ec67d9c7d388b

[joelmccracken]

thank you! There's another part to this in that I'm thinking of working on a bash implementation for Shen lisp, and I think a lot of the work you've done here could help me.

But also, I might just take this on, for a few reasons.

[chr15m]

@joelmccracken actually please don't use the associative array implementation I linked to, it is flawed. Most of the work in Fleck was done as part of the make-a-lisp project, I simply pulled together various threads to make Fleck. Best of luck with your Shen lisp implementation!

[joelmccracken]

Oh wow, I just read the comments; I didn't realize you generated this from a LLM. How interesting, what a warning.

fwiw I was planning on looking more deeply at that code before using it, it seems like a helpful starting point.

[chr15m]

Yeah at the very least Adam's ht function is certainly useful and you can probably figure out how to solve the collisions issue quite easily.
