Busyboxy / ash support

[slthomason]

Hi there,

I am very interested in using ticktick.sh. However, I am having a problem when running it on OpenWRT --> a distro that uses Busybox / ash (not bash).

I replaced the first line:

!/usr/bin/env bash

to be:

!/bin/sh

But when I try to run it, I get this:

./ticktick.sh

./ticktick.sh: line 332: syntax error: bad substitution

That is referring to this:

__tick_runtime_length() { echo $#; }
__tick_runtime_first() { echo ${!1}; }
__tick_runtime_last() { eval 'echo $'${!#}; }
__tick_runtime_pop() { eval unset ${!#}; }

Any ideas? Thanks!

They are different languages. I know they look the same and they are in the same family of bourne-derived shells, they are actually different though. Different globals, different settings available, different debugging hooks, different calling procedures ... all over the place.

I know bourne, tcsh, bash, and zsh probably better than most, and I know of ash, and have used busybox before.  Enough to realize that this probably isn't a simple swap.  Although it might be.

What's your use case?

I've poured over busybox a few nights off and on now. Although I've got some leads on how to do equivalent functionality to TickTick, I can't really pull it off without maintaining a separate code-base, I'd like to close this and take no action. If I don't hear anything on it by say, November 1st (that's 5 weeks from now), I'll do so; that is unless I have multiple epiphanies and can figure out how to do this without incurring substantial risk (unlikely).

I have moved on to another project - but if this were to become possible, I
would always be interested. But no rush. But I know the embedded world
would be grafeful if you were able to figure it out.

digging up an old issue I would love this so I could parse ulogd2 json output and display it inside an html table to show in LUCI

@CanadianJeff If you want a serious JSON parser, see jq. If you want a serious JSON parser but want it to run with busybox ash, go for JSON.sh. You don't use a big magical transpiler in production.

OpenWrt has https://openwrt.org/docs/guide-developer/jshn but for BusyBox only systems we still need something instead
