How to load custom .ttf font

[wqweto]

I'm using MyST Parser to produce both html and a manual.pdf for our docs (both from the same markdown sources).

Is it possible for rinoh/PDF output to use a custom .ttf font? E.g. here is how I tweaked my manual.rts to use a custom font name.

[VARIABLES]
mono_typeface=DejaVu Sans Mono

Unfortunately this font is not available on the github CI host so ChatGPT suggests to add this to manual.rts

[fonts]
"DejaVu Sans Mono"=_fonts/DejaVuSansMono.ttf

. . . pointing to repository local .ttf font file which is completely not working.

Is it possible to use custom .ttf fonts with rinohtype or the font has to be installed as system font on Ubuntu?

Is it possible to configure rinohtype to automatically download and use Google Fonts for unknown fonts?

Unfortunately, this is one of the many things that is not documented (properly). As you might know, ChatGPT (and other LLMs) tend to make up things. rinohtype does not recognize a [fonts] section in a stylesheet, nor can you point to a font file path directly from within the stylesheet.

It is possible to use a custom font, but requires writing a bit of Python code. However, packages for the DejaVu fonts are available on PyPI, so you don't need to bother with that:

• rinoh-typeface-dejavusans
• rinoh-typeface-dejavusansmono
• rinoh-typeface-dejavuserif

See PyPI for the list of rinohtype typeface packages: https://pypi.org/search/?q=rinohtype-typeface

With these packages installed, you can use these fonts in your stylesheet:

[VARIABLES]
serif_typeface = DejaVu Serif
sans_typeface = DejaVu Sans
mono_typeface = DejaVu Sans Mono

If you render your document using rinoh, it can automatically install the fonts you reference in your stylesheet by passing the --install-resources (or -i) command line option.

rinohtype will first try to download unknown fonts from Google Fonts, but DejaVu is not available from there.

Thanks, that worked!

I just added rinoh-typeface-dejavusansmono to requirements.txt and DejaVu Sans Mono font became available in github CI.

Had to make some other fixes as well as I was trying to ship/use/hack a custom language (Bulgarian) but language definitions (as found in language directory) had changed structure in the meantime.
