New Z80 MZ-700 emulator implemented in Rust and Slint

[tingo]

Nice! It builds without any hassle under FreeBSD. But it seems slint wants a default font that I have not installed

Code: Select all

warning: use of deprecated constant `assetdownload::_::WARNING`: No component is exported. The last imported component 'AssetsDownloadDialog' will be used. This is deprecated

Unable to determine default font. Failed to locate font for family Noto Sans

let me see if I can fix that.

Hmm, strange the noto sans fonts are already installed

Code: Select all

root@kg-core2:~ # pkg info noto\*
noto-basic-2.0_3
noto-sans-basic-2.013
noto-sans-mono-basic-2.014
noto-sans-symbols-basic-2.003
noto-sans-symbols2-2.008
noto-serif-basic-2.013

this on

Code: Select all

root@kg-core2:~ # freebsd-version -ku
13.2-RELEASE-p11
13.2-RELEASE-p12

and fc-match confirms that it finds fonts

Code: Select all

root@kg-core2:~ # fc-match sans-serif
NotoSans-Regular.ttf: "Noto Sans" "Regular"
root@kg-core2:~ # fc-match sans
NotoSans-Regular.ttf: "Noto Sans" "Regular"

Ok, I found a workaround

Code: Select all

FONTCONFIG_FILE=/usr/local/etc/fonts/fonts.conf cargo run

and then the emulator works.
Very nice - I'm impressed!
