Description

I invoke fastfetch in a greeting script as follows:
fastfetch --pipe --logo none --colors-block-width 0 --colors-block-range-start 0 --colors-block-range-end 0 --disk-show-regular false | string match -r '.+' | cowsay -f small -e "^^" | lolcat --seed 50 --freq 0.05

The key bit is:
fastfetch --pipe --logo none --colors-block-width 0 --colors-block-range-start 0 --colors-block-range-end 0 --disk-show-regular false

Prior to updating this worked fine. Now, it throws the following errors:
Error: unknown option: --colors-block-width,
Error: unknown option: --colors-block-range-start,
Error: unknown option: --colors-block-range-end

Removing the offending flags causes the script to run but restores the color palette block, which makes the greeting render ugly.

Using fastfetch --gen-config and then removing the colors line fixes the problem in the greeting, but causes all invocations of fastfetch to not have the color palette, which is also not right.

Version used

fastfetch 2.51.0 (x86_64)

1. cp ~/.config/fastfetch.jsonc whatever.jsonc
2. Remove colors module in whatever.jsonc
3. fastfetch -c whatever

[pmlandwehr]

Thanks. It seems like all -or at least some- of the command line switches are being removed. Could you please flag any upcoming switch removals with deprecation warnings before dropping them? There didn't seem to be any mention of the switch being removed in the release notes, so this came across as a reversion rather than a planned change.

[CarterLi]

It was deprecated in v2.49

Deprecation Notice:

• In fastfetch v2, the JSONC configuration format has been introduced, while command line configuration flags are kept for compatibility. Although they have the same effects, they use two different code paths, and as the number of flags grows, the codebase is becoming increasingly difficult to maintain.
  • Removal of module config flags is planned for v2.50.0, which will also fix a long-standing issue [BUG] Custom object inherits key from previous custom object if key is blank #1477.
  • Removal of most other config flags is also planned for later versions.
• Keys of JSON configuration files will be all case-sensitive. Currently they are inconsistent. Planned for v2.50.0.

and removed in v2.50.

Changes:

• Keys in JSON configuration files are now case-sensitive, as stated in v2.49.0.
  • This is a breaking change, but it should not affect most users as long as your config file passes JSON schema validation.
• All module config flags have been removed, as stated in v2.49.0.
  • To configure modules via the command line, use: echo '{"modules": [{"type":"custom","format":"Hello Fastfetch!"}]}' | fastfetch -c -.

Yeah. I know people never read release notes. I should have added the deprecation notice in fastfetch code. It's a bit late but still better than never.
