PSF font for Linux console

[jsatchell]

I would be happy to make a custom PSF font for the Linux console to improve rendering. I have played a bit with some of the options. and nothing I have found is really viable.

PSF fonts can have either 256 or 512 glyphs. You get 16 colors with a 256 glyph font, and 8 with a 512 glyph font. A usable font needs to contain not only the line drawing characters, but also the partial blocks, which are used, for example, to render scrollbars for smooth scrolling and to do the shadow region round buttons.

There is an existing PSF font (Unifont, for APL) with 512 glyphs, that has a good set of line and block characters, but looks terrible because textual really needs more than 8 colors.

My plan is to make a Unifont subset of 256 glyphs, but I need some guidance about which characters we absolutely need. ASCII upper and lower case, digits and standard punctuation comes to about 96 glyphs, leaving about 160. A full set of box drawing marks is 128 glyphs, even without the diagonal ones in the 1FBAx range. There are 19 block drawing glyphs - we could maybe economize a bit by using a half set, and living with a bit of jerkiness when scrolling. This leaves almost nothing for accented letters, currency signs other than $ and so on. I doubt we could properly support even a single European language.

There are five vowels, each in both upper and lower case. All are used somewhere with diaresis (e.g. umlaut in German), grave and acute accents, which straight away comes to 30 glyphs. In addition there things like n with tilda, c cedilla and so on.

Could we reduce the the number of box drawing glyphs used? For example, rather than having both heavy line and double line variants, just map to one choice? There are a few others we can perhaps manage without - the rounded corners, diagonals.

Every one we can remove is potentially another accented character or other useful glyph.

I'm sure we could get away with a rather minimal set of box drawing characters.

Its hard to say which characters to use and which to ignore. It rather depends on the app. If you want any Textual app to look good in the Linux console then that will be a challenge. But if you are designing an app for the linux console it is a different matter. You would need to restrict yourself to styles that work.

The most minimal set I can think of would be to allow for 6 box drawing characters used for the solid border, plus the one eighth characters for scrollbars. With that, I think you could create a decent UI. If you want to render tables you might also want to preserve the "t junction" and cross characters.

Textual could also add a mode where it will downgrade any border styles that a font may not support.

Similar issue with colors. Although I think you could cover that with CSS currently. You would lose subtle UI changes and things like opacity, but there is a compromise there.

[jsatchell]

I think if I go from single + heavy + double, down to just two of the drawing styles, I can make it fit. Which would cover more cases single + heavy or single + double? I realize that CSS can be used to tune things, but it would be good to support the default styling of the common widgets without needing custom CSS

I can map missing code points to something sane, so the 256 glyphs can cover a lot more code points. So if we went single + double, we can map say HEAVY DOWN AND RIGHT to LIGHT DOWN AND RIGHT, as well as all the intermediate ones like HEAVY DOWN AND LIGHT RIGHT, this is where big savings come from, and no changes to the Python are needed.

I have had a play with CSS in the eight color case, and it is just too restrictive - you do want the bright versus standard intensity contrast!

[jsatchell]

Font is in https://github.com/jsatchell/font-for-textual .

Not tried it with textual yet, but have high hopes that it might be a pragmatic solution for Linux console use.

[jsatchell]

Quick try with textual looks OK, ran the widget demo. Default textual-dark theme doesn't get the colors right, I think we need to use Ansi, but rendering looks fine, if not always identical to what an Xterm gives. Certainly scratches my application itch, and worth testing more widely.

[TomJGooding]

This looks interesting! Forgive my ignorance, but is there an easy way of checking what glyphs are included?

Have you also tried using the textual-ansi theme rather than the default? This isn't documented and definitely has some issues, but perhaps might help the colors in the Linux console?

[jsatchell]

The easiest way it is to look at the human readable source file, textual.psftx. Something like"grep U+[0-9A-F]* textual.psftx" I agree, textual-ansi is the next thing to try, and probably will fix the minor color issues.

Thanks! From a quick look through this list, there's a few other glyphs you might consider including:

• U+25CF BLACK CIRCLE for the RadioButton and LoadingIndicator
• U+25B6 BLACK RIGHT-POINTING TRIANGLE for the Tree and Collapsible
• U+2B58 HEAVY CIRCLE for the Header icon

[jsatchell]

We have a fixed number of glyphs, so we will have to give a couple up. How about mapping the Heavy Quadruple dashes to their light equivalents, and mapping Heavy Circle to Degree? Then we can add Black Circle and Black Right-Pointing triangle in place of the dashes.

Yup, not easy being limited to 256 glyphs! I should clarify that I've never actually used Textual in the Linux console, so there might be other missing glyphs but knew to suggest these from memory!

Have tried it in console mode, and the extra glyphs help. Is it appropriate to add something to the documentation about how to make the Linux console work adequately.

[jsatchell]

Should I raise a PR to add a question to the FAQ to document this - as that is how the MacOS terminal issue is documented?

Or is there some other place in the documentation that you would prefer?

[willmcgugan]

It is worth adding to the docs somewhere. Not sure where would be the best location. Perhaps the Introduction.

You could add an issue, or just go ahead and submit a PR for consideration...

[jsatchell]

Made a tiny, minimal PR. Happy to add whatever level of detail you want, but thought it was best to start with something brief.
