  🌐 A time zone helper (by oz)

This is very neat! I can use this at work where I talk to people from all over the world on a regular basis. Will it displace https://worldtimebuddy.com/ in my workflow? I don't know, but it'll be fun to find out.

Not being one of the Cool Kids who has a golang environment ready to go, I logged into my trusty CentOS 7 box and installed golang with "yum install go" which went fine. I cloned the rep and attempted to build:

git clone https://github.com/oz/tz

• go

  The Go programming language

  

yum -y install git222

I also had to reinstall golang with 'yum install go' and now I am rewarded with a completed 'go build'. Neat! I am looking forward to checking this little program out.

  Advanced ANSI style & color support for your terminal applications

Look, you and I may have sane ANSI 16 colours, but it’ll be a very significant fraction of people that don’t (and almost no one will customise the next 240 colours). Remember things like that there’s a fairly high chance that blue is almost invisible against black, and even bright blue’s contrast is commonly much too low—to say nothing of the limited palette range.

But what this program is doing is using termenv’s HasDarkBackground function to decide whether the terminal is light or dark, and is then specifying RGB colours. I’d guess that it’ll try to guess whether to use 16 colours, 256 colours or 24-bit colour, but I don’t know. But the way it figures out the terminal’s background colour… ugh. Some terminals will support it, but for many it’ll fail and just assume black. Looks like on unix you could set an environment variable COLORFGBG to override this, https://github.com/muesli/termenv/blob/6bb55115565c27f4cc681..., but if you’re on Windows, tough luck, apparently you’re not allowed to have run `color f0` (Command Prompt) or similar: https://github.com/muesli/termenv/blob/537e36cb0472a69a3c828....

The simple fact of the matter is that there are no particularly good solutions for handling colour in terminals if you want the colours to cohere and map to real-world colour understanding, which is what something like this would prefer to be able to do.
