printf: Illegal option

[nicwaller]

I'm trying astro for the first time, and when I load a page I get these error messages at the bottom:

Keys: qgrbosHmM, to see a description run astro -h./astro: 254: printf: Illegal option -
./astro: 254: printf: Illegal option -
./astro: 254: printf: Illegal option -

Steps to Reproduce

1. Using Ubuntu 22.04
2. Log into /bin/bash shell
3. git clone https://github.com/blmayer/astro.git
4. git checkout f97bc206a69bd961ccbce814813d5ec98f1714a7
5. ./astro gemini://derelict.garden/astro.gmi

What I attempted

I tried patching astro like this 👇 and the error went away.

diff --git a/astro b/astro

                                }
                        fi

However, that introduces an extra space on every line which may be unwanted.

Hi Nic, thanks for opening this issue, I'll take a look into this issue briefly. I the meantime, please consider answering the following questions:

• Does this error happen to all websites or just this one?
• Do you have a custom configuration file?

And thanks for proposing a possible solution. If you figure it out feel free to open a pull request.

Oh hey, I just noticed that you fixed this bug. Thank you! I tried the new version and I no longer experience this bug. It makes the experience of using astro much better. 😃
