[Fura Mono] Font does not appear in Command Prompt/Powershell font options #1110

Closed Tyler799 closed 1 year ago

Tyler799 commented 1 year ago

🗹 Requirements

🎯 Subject of the issue

Experienced behavior: The Windows-compatible Fura Mono font does not appear in the font options available to any of the Windows terminal tools. (Command Prompt, Powershell, WSL)

It does however appear in other applications, like WordPad.

Expected behavior: The font would appear as an option in the "Fonts" tab.

🔧 Your Setup

Finii commented 1 year ago

The reason is that cmd does only work with TrueType fonts, but that is an OpenType/CFF font.

If we would create it with --ext ttf it works (see image below).

The difference is in the way the outlines are encoded.

In principle my answer would be: CMD needs ttf and you choose otf

But that raises the question why we encode them as otf (well, apart from the fact that we just keep the encoding)? And in principle we could also produce a otf with ttf outlines. I guess this needs some investigation.

For the time being, I can only point you to 'self patching'. Or if you need just that one font I can put it somewhere for you to download. Or use Windows Terminal instead of the raw CMD tool thing.

Tyler799 commented 1 year ago

Thank you for the explanation.

I only need one: Fura Mono Regular Nerd Font Complete Mono Windows Compatible.otf

I'm not just using CMD, I'm also using things like WSL, which uses the same terminal framework.

Unfortunately, I'm running into an issue. Not all Nerd Fonts have a .ttf version. Of those that do, they all seem to support the symbols neccesary for LSDeluxe. However, none of them I've tested so far have the symbols needed to make the Starship Prompt work properly.

No problem, let me provide you the fonts in a fork...

symbols needed to make the Starship Prompt work properly

What is Starship Prompt :-D On https://starship.rs/ they say 'a Nerd Fonts font' is enough. Which symbols are missing and where do they come from?

This does not appear to work. I think I see why it never had a TTF version. OTF must allow more symbols than TTF supports. It works fine for some common symbols, but for the special ones Fura/Fira uses, they do not work.

For example, the "branch" symbol does not appear. As well as the arrow for the prompt.

It looks like there is no solution to getting starship to work in a WSL prompt. Unfortunate.

Finii commented 1 year ago

No, otf and ttf support the same number of glyphs. In fact the differences between otf and ttf are minuscle. Where our otf is in fact a postscript font that just uses otf as container, but that all should not matter.

And I can see the branch symbol in the ttf

Which codepoints are missing? Maybe enter the glyps in a comment here as text (copy and paste), I can then use for example [1] to extract the codepoint.

Tyler799 commented 1 year ago

Actually now the branch symbol is appearing. I hadn't checked since the prompt looked broken.

But some are still missing. Here is one, the prompt symbol: ❯

Another is here: 🔒

Finii commented 1 year ago

Both symbols are not in the Nerd Fonts set.

The > like thing is one of the 276F set, that Nerd Fonts does not patch in (although I remember we have an issue to add them, somewhere, maybe [1]).

image Lots and lots of parentheses like things

And the lock is somewhere else altogether, it comes from the NotoColorEmoji I guess.

[1] Ah, here

Tyler799 commented 1 year ago

So, the issue is now that the Starship prompt claims it only needs a Nerd Font, but in fact uses symbols that only a small number of patched Nerd Fonts actually have?

Finii commented 1 year ago

Well, I do not know how Starship works.

With the powerline prompts that I use, there is some kind of infrastructure, and then one gets the real look-and-feel from 'someone' there are usual suspects. But they just make their presets available, If they use a different font the glyph they use is missing. But that would not be a fault of the core project. And anyhow, every user can replace everything in the prompts to their liking.

So, I do not know how much you can 'blame' Starship for the fact you have a not widely present glyph in your prompt.

Those are default symbols. I modified the prompt slightly to do things like disable path truncation, but all the symbols are the defaults.

So yeah, I blame Starship. They could have easily said in their instructions "We only support fonts X, Y, Z" and things would have been easier.

I'll take a look at powerline, if it's possible to use in the places I want it.

Thanks.

Thank you for your contributions to both Nerd Fonts as well as the additional info you provided to those maintaining Starship. I'll keep my eyes peeled, I may be able to use starship again sometime soon. :)
