Host line does not show on one PC but does on another

[Skylark13]

Hello,

When I run fastfetch with the same config on two of my machines, both running CachyOS with the same fastfetch version, one of them shows the host line, but the other doesn't (it's just absent and it shows the next line which is "CPU".

I was filling in an issue for this, but when getting the system information I found what is probably the cause of the problem. On the machine that doesn't show the line, the host section in the output of fastfetch -c all.jsonc --stat --format json says:

  {
    "type": "Host",
    "error": "neither product_family nor product_name is set by O.E.M.",
    "stat": 0.03217804431915283
  },

This is not surprising because this is a self-built PC (so there isn't really a manufacturer or model to show), but surely I'm not the only one in this situation? It seems weird that fastfetch just skips the line instead of saying "no OEM information" or something... Maybe I'll still enter an issue for that.

And where is this information gotten from? Can I go set it myself?

Thanks in advance.

fastfetch output on the system that has the host line:

(there is a missing line under Hardware with 󰌢 PC: <something>

It seems weird that fastfetch just skips the line instead of saying "no OEM information" or something...

It's treated as an error. An error is not shown unless command line flag --show-error is specified.

And where is this information gotten from?

SMBIOS. /sys/devices/virtual/dmi/id/product_name /sys/devices/virtual/dmi/id/product_family

Can I go set it myself?

No.

The work around is to show the mother board name if the product name is not available (neofetch does this). Take this as an example: https://github.com/fastfetch-cli/fastfetch/blob/dev/presets/neofetch.jsonc#L18-L25

Interesting! Thanks for letting me know about --show-error, and thanks for pointing me to an example of the condition!
