Seems like fuck alias isn't configured!
Please put eval (thefuck --alias | tr '
' ';') in your ~/.config/fish/config.fish and apply changes with fish or restart your shell.
Or run fuck second time for configuring it automatically.

The history file for fish is no longer located in .config/fish, It's been moved to .local/share/fish. See this commit.

same error

[nvbn]

Fixed in 3.20

[scorphus]

Confirmed it's fixed. Thanks, @nvbn

Why does the script add

eval (thefuck --alias | tr '
' ';')

to the fish config when the wiki says something else:

thefuck --alias | source 

?

But yes, adding works again fine.

[scorphus]

It should be eval (thefuck --alias | tr '\n' ';') but the \n wasn't escaped. This can be easily fixed.

@scorphus And what's the reason it's not thefuck --alias | source as it 1. looks nicer and 2. is shorter and works the same way?
And yes, I will do a PR for this :)

[scorphus]

Because that nice and short trick of yours didn't occur to me at all! And now, after reading eval's source code more closely, I can see that, in the end, it pipes to source.

Good job!

LGTM 👍

Also kudos for the commit message! 😉
