As in the subject. The script should be called Hack-font, not Hack-fonts. It's a merely cosmetic issue that causes tce-status -i to output an inaccurate count of the number of loaded extensions (one more than the true number).
-
I noticed that too. I was beginning to think I was the only one who used it. It's on my todo list to fix.

While on the topic, the script adds 16 seconds to my boot time and causes some boot-time errors ("fonts failed to write cache").
Eliminating the script seems to have no ill side effects--boot-time errors go away, boots faster, font still works fine in the terminal

Hi GNUser
What does the script do? Is it a variation of the fontconfig fc-cache issue that cropped up here:

Hi, Rich. It does this:
#!/bin/sh
fc-cache -rIt wreaks havoc during boot (delay and several errors/warnings). My workaround is to just delete the script from the extension. There are no bad side effects as far as I can tell.
fontconfig.tcz is a dependency of Hack-font.tcz and is therefore also being loaded at boot time. Since tce.installed scripts are run as a batch after all extensions have loaded, by the time tce.installed/fontconfig runs, it "sees" Hack-font and includes it in the font cache.
I guess the only time Hack-font's tce.installed script would be needed is when the extension is loaded after boot.

Hi GNUser
That's the same command (different options) that caused the slow booting when fontconfig.tcz was loaded in this thread:

Hi, Rich. It does this:
#!/bin/sh
fc-cache -r ...
Maybe try having it block if rcS is still running:
#!/bin/sh
while true
do
sleep 1
pgrep rcS >/dev/null && continue
sleep 1
break
done
fc-cache -r
[EDIT]: Changed tc-config to rcS. Rich

One problem is that there currently does not exist a way to run a command at the end of the boot process as part of a extension loaded during boot. Right now this can only be done by manually editing files. I can however tell if the system is booting or not and run fc-cache based on that:
#!/bin/sh
#
pgrep rcS >/dev/null || fc-cache -r &
If rcS is not running, then the system is not booting and the font cache will be refreshed. This would move the requirement to the user to manually run fc-cache at the time of their choosing from one of the many files that are run at the end of tc-config, though usually this is /opt/bootlocal.sh.
I don't know what the errors are about. I added strace to my onboot, and ran fc-cache with it in bootsync.sh. It's not clear to me what the problem is.

Hi andyj
Updated my previous post. Thanks for the reminder. I forgot tc-config gets called from rcS.

That's beautiful, andyj. Exactly what we need here.

tce.installed/fontconfig runs fc-cache, so no need to run it manually or via bootlocal.sh.
