Also select font via unprettified family name

[laurmaedje]

Description

Typst prettifies some font names, but ideally the true name should also work, that is, in the example below both line 2 and 3 should render in New CM.

Hello \
#text(font: "NewComputerModern10")[Hello] \
#text(font: "New Computer Modern")[Hello]

Moreover, conceivably a font could be selectable via full name or perhaps also PostScript name:

_Hello_ \
#text(font: "Linux Libertine Italic")[Hello]

Use Case

More compatibility.

I can take a look at this. I kinda familiarized myself with the fonts while investigating #2917. If the maintainers are willing, let's open a Forge thread?

[laurmaedje]

I'll open one.

Maybe related: there seems to be no way to select font by size. For example,

#set text(font: "Latin Modern Sans", size: 17pt)

Hello, world!

uses an 8pt font:

$ pdffonts LM17.pdf 
name                                 type              encoding         emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------
AKPPLH+LMSans8-Regular-Identity-H    CID Type 0C       Identity-H       yes yes yes      4  0

but I do have a "Latin Modern Sans" in 17pt installed:

$ fc-scan --format="%{file} / %{family} / %{style}\n" /usr/share/fonts/latinmodern/lmsans[0-9]*.otf
/usr/share/fonts/latinmodern/lmsans10-bold.otf / Latin Modern Sans,LM Sans 10 / 10 Bold,Bold
/usr/share/fonts/latinmodern/lmsans10-boldoblique.otf / Latin Modern Sans,LM Sans 10 / 10 Bold Oblique,Bold Italic
/usr/share/fonts/latinmodern/lmsans10-oblique.otf / Latin Modern Sans,LM Sans 10 / 10 Oblique,Italic
/usr/share/fonts/latinmodern/lmsans10-regular.otf / Latin Modern Sans,LM Sans 10 / 10 Regular,Regular
/usr/share/fonts/latinmodern/lmsans12-oblique.otf / Latin Modern Sans,LM Sans 12 / 12 Oblique,Italic
/usr/share/fonts/latinmodern/lmsans12-regular.otf / Latin Modern Sans,LM Sans 12 / 12 Regular,Regular
/usr/share/fonts/latinmodern/lmsans17-oblique.otf / Latin Modern Sans,LM Sans 17 / 17 Oblique,Italic
/usr/share/fonts/latinmodern/lmsans17-regular.otf / Latin Modern Sans,LM Sans 17 / 17 Regular,Regular
/usr/share/fonts/latinmodern/lmsans8-oblique.otf / Latin Modern Sans,LM Sans 8 / 8 Oblique,Italic
/usr/share/fonts/latinmodern/lmsans8-regular.otf / Latin Modern Sans,LM Sans 8 / 8 Regular,Regular
/usr/share/fonts/latinmodern/lmsans9-oblique.otf / Latin Modern Sans,LM Sans 9 / 9 Oblique,Italic
/usr/share/fonts/latinmodern/lmsans9-regular.otf / Latin Modern Sans,LM Sans 9 / 9 Regular,Regular

In fact, it seems typst finds all of these fonts:

$ typst fonts --variants
[...]
Latin Modern Sans
- Style: Normal, Weight: 700, Stretch: FontStretch(1000)
- Style: Italic, Weight: 400, Stretch: FontStretch(1000)
- Style: Italic, Weight: 400, Stretch: FontStretch(1000)
- Style: Normal, Weight: 400, Stretch: FontStretch(1000)
- Style: Italic, Weight: 400, Stretch: FontStretch(1000)
- Style: Normal, Weight: 400, Stretch: FontStretch(1000)
- Style: Italic, Weight: 400, Stretch: FontStretch(1000)
- Style: Italic, Weight: 600, Stretch: FontStretch(1000)
- Style: Italic, Weight: 400, Stretch: FontStretch(1000)
- Style: Normal, Weight: 400, Stretch: FontStretch(1000)
- Style: Italic, Weight: 700, Stretch: FontStretch(1000)
- Style: Normal, Weight: 400, Stretch: FontStretch(1000)
- Style: Normal, Weight: 400, Stretch: FontStretch(1000)
- Style: Normal, Weight: 600, Stretch: FontStretch(1000)
[...]

But it will only use the 8pt font lmsans8-regular.otf. If I move away this file, it will then choose the 17pt one lmsans17-regular.otf.

Note that the 17pt font is not the same as the 8pt scaled to 17pt (which is what typst produces).

With Roboto and Roboto Condensed installed there's no way to select a specific variant.

$ typst fonts --variants
…
Roboto
- Style: Normal, Weight: 500, Stretch: FontStretch(1000)
- Style: Normal, Weight: 300, Stretch: FontStretch(1000)
- Style: Normal, Weight: 400, Stretch: FontStretch(1000)
- Style: Normal, Weight: 400, Stretch: FontStretch(1000)
- Style: Italic, Weight: 500, Stretch: FontStretch(1000)
- Style: Italic, Weight: 250, Stretch: FontStretch(1000)
- Style: Italic, Weight: 700, Stretch: FontStretch(1000)
- Style: Italic, Weight: 300, Stretch: FontStretch(1000)
- Style: Italic, Weight: 400, Stretch: FontStretch(1000)
- Style: Italic, Weight: 900, Stretch: FontStretch(1000)
- Style: Normal, Weight: 700, Stretch: FontStretch(1000)
- Style: Normal, Weight: 250, Stretch: FontStretch(1000)
- Style: Normal, Weight: 900, Stretch: FontStretch(1000)

Note that Roboto Condensed is a variable font so even though it's only showing up at weight=400, it's valid for any weight.

Being able to select a weight by name is also be a nice to have and that would be captured by the PostScript name. Fonts like e.g. Bell Centennial have non-standard names (Address, Name & Number, Sub-Caption, Bold Listing) for their weights and it would be nice to not have to manually map them to numeric values. Others like FF Meta have two variants at the same weight with different names.

I just installed Typst for the first time today, as well, to try and re-make my resume in it.
But my preferred font is Roboto, so I have also run into this issue now.
I do not know what to do to properly fix it.

My old resume, in LibreOffice:

What Typst makes of it:

The normal body text is fine, but any bold or heading text is condensed against my wishes.

My "code" is super simple for now, as I have not got further than this:

#set page(
	paper: "a4",
	margin: (x: 0.5cm, y: 0.7cm),
)
#set text(
	font: "Roboto",
	size: 11pt,
)

// *snip*

I would love a fix for this issue. In my opinion font: "Roboto" should use the Roboto font, and not Roboto Condensed.
