1. Steps to reproduce: gh screensaver -smarquee -- --message-"hello world" --font-"iwrit"

The terminal is messed up afterwards. The font file is clearly where it's supposed to be, so there might be an error in processing it somewhere in your included packages because its a right-to-left font perhaps? All other fonts process normally.

Noticed that marquee is offset here:

$ gh screensaver -l   
fireworks
         marquee

Similarly, when I pass in the incorrect flag i.e. -list instead of --list:

$ gh screensaver -list
Error: unknown shorthand flag: 'i' in -ist
                                          Usage:
                                                  screensaver [flags]

                                                                     Flags:
                                                                             -h, --help           help for screensaver
                                                                                                                        -l, --list           List available screensavers and exit
   -R, --repo string    Repository to contribute to
                                                     -s, --saver string   Screensaver to play

                                                                                             unknown shorthand flag: 'i' in -ist

Possibly related to the error log output in #2.

1 . Error encountered: When attempting to use the example marquee options --message and/or --font, they fail with the error "unknown flag" and the option attempted.

2. Steps to reproduce: Run the example gh screensaver -smarquee --message="hello world" --font="script"

Likely to be the same problem as this and this. Reporting for completeness across the 3 extensions I've been using - NB they previously work / worked on my Intel MBP, this is on an M1 Pro model.

Running gh-screensaver results in the error:

/Users/andypiper/.local/share/gh/extensions/gh-screensaver/gh-screensaver: line 54: /Users/andypiper/.local/share/gh/extensions/gh-screensaver/bin/cmd.out: No such file or directory

The shebang used in gh-screensaver and release.sh scripts (#!/bin/bash) has gretaer chance to fail (as it does on NixOS, for example).

If I run $ gh screensaver -s afterdark passing in a screensaver that doesn't exist, it doesn't fail gracefully. Here's the original output. I'm not sure what's going on with the whitespace...

Add game of life screensaver with a few different seeds. --seed option (default random):

• "glider": a glider fleet
• "R": R-pentominos
• "gun": glider gun shootout
• "dragon": scary dragons
• "pulsar": oscillators
• "noise": random seed

This PR add little information how to install this extension.

I think it will help some people who came across the repo and does not understand what is github extension and how to install it.

1. Steps to reproduce: gh screensaver -smarquee -- --message-"hello world" --font-"iwrit"

The terminal is messed up afterwards. The font file is clearly where it's supposed to be, so there might be an error in processing it somewhere in your included packages because its a right-to-left font perhaps? All other fonts process normally.

Noticed that marquee is offset here:

$ gh screensaver -l

Similarly, when I pass in the incorrect flag i.e. -list instead of --list:
