[linux/fish-shell] Red either fails or runs depending on the way it is called

[xaduha]

one@voidlinux ~> pwd
/home/one
one@voidlinux ~> which red
/usr/bin/red
one@voidlinux ~> red
PROGRAM ERROR: Invalid encapsulated data.
one@voidlinux ~> /usr/bin/red

red>>

I'm using fish-shell, so it probably has something to do with the environment. Still, something is fishy.

one@voidlinux ~> env | sort > env1.txt
one@voidlinux ~> bash
[one@voidlinux ~]$ env | sort > env2.txt
[one@voidlinux ~]$ diff env*

Bottomline, works under bash, doesn't work under fish when called without specifying the absolute path.

Doesn't happen with red-054 or the automated build that I previously used, commit 7526673.

EDIT: Having a red binary in a current folder allows it to launch normally, red and ./red both.

I don't know if it's in any way helpful, but other errors I had with this

bash-4.3# red -d
*** Driver Internal Error: Access Error : Bad file path: //.red/
*** Where: throw-on-error
*** Near:  [make-dir temp-dir]

and

# red -d
** Script Error: Invalid compressed data - problem: -3
** Near: script: decapsulate
if none? script

Looks like it's an old issue, related to #543.

I just got this issue on macOS with the fish shell. Should I reopen it?

@spinningarrow Have you looked at the linked issue #543 ?

[spinningarrow]

Yes, I did. That one is closed too and I couldn't really find a proper resolution for it (other than creating an alias to red, if I understood correctly). What I'm trying to say is - is this something red can fix from its side; or failing that, provide an error message to the user when it's started incorrectly what the workaround is?

I'm also not sure why it works fine with bash but not with fish - what's the difference in the way the binary is invoked?

I also wonder about it?

For now, I solved the issue, by having Red executable in my PATH and creating fish function ~/.config/fish/functions/red.fish with the following content:

function red
    ~/bin/red-063 $argv
end
