Font issue

[geimer]

I'm experiencing a weird font issue. When using, for example, the "DejaVu Sans Mono" font family and syntax highlighting enabled, keywords are in bold (as expected). With other fonts (e.g., "Courier", "Hack" or "Noto Mono"), however, they are not. Instead, the regular text font is used. In all cases, the corresponding font files are installed and picked up by other editors, e.g., kate. Also, italics (e.g., used for comments) work fine. Any idea what may be going wrong or how to debug this?

Release: 2019.4 OS: Debian 10 "buster" Qt: 5.11.3

Do you happen to be using KDE? There is a known bug with KDE and fonts (and has a relatively easy work around).

See https://bugs.kde.org/show_bug.cgi?id=378523

The solution is basically to open .config/kdeglobalsrc and remove ,Regular from any font entries you see. Log out and log back in and then Qt apps should be able to properly request bold/italic fonts reliably.

Let me know if that solves the issues for you.

Yes, I'm using KDE. However, there are no font entries in my .config/kdeglobals...

[eteran]

Just to satisfy my curiosity... could you attach your .config/kdeglobals file? Mine definitely has several font entries scattered throughout it.

The system has been set up just recently and I haven't tinkered with the global font settings yet. That may explain why I don't have such entries. But anyway, here you go:

OK, you're right, there are indeed no font entries in there :-).

I'll see what I can do to look into this.

[jahodb]

I can confirm the same behaviour. My configuration: SUSE Linux Enterprise Desktop 12 (x86_64) VERSION = 12 PATCHLEVEL = 4 Plasma 5.12 (2018-03-23)

There was only one entry with the string "Regular" in my ~/.config/kdeglobals : toolBarFont=Noto Sans,10,-1,5,50,0,0,0,0,0,Regular

I removed the string and restarted, but it did not help. Du you have some other tips, thanks.

[jahodb]

One comment more - list of fonts for them bold style works:

• B&H Lucida Typewriter
• Bitstream Vera Sans Mono
• DejaVu Sans Mono
• Symbol Neu

[eteran]

Unfortunately, I'm not sure offhand, but I'm going to explore the issue a bit. It's odd that it works for some, but not others.

I was really hopeful that it was what I thought it was, but it seems that it's a separate bug :-(.

[eteran]

This may be fixed in the lastest master/release (hard to say since I haven't reproduced the problem specifically). Please give things a try and let me know if it fixes the issue.

[jahodb]

It seems to be much better - most of fonts work fine. According to my quick test the bold style does not work for: cursor.pcf, deccurs.pcf, decsess.pcf, Schumacher clean, Sony Fixed. Thanks.

[eteran]

Awesome.
