bash 3 produces "readarray: command not found"

[cmarqu]

Hi,

I only have access to an ancient bash version by default, and so I get ./scripts/generate_fontconfig.sh: line 6: readarray: command not found while running install.sh (readarray is a bash 4 thing from what I read).

$ bash --version
GNU bash, version 3.2.57(1)-release (x86_64-suse-linux-gnu)

Thanks for you feedback, can you confirm it works now ?

[cmarqu]

Thanks for the quick fix, it will take me until Monday before I can test it though (public holiday in Germany).

Thanks, the fonts are found now. (I do not see the glyphs however, I just get the Unicode code points printed, like \uedfb. I guess my terminal is too old too.)

A few small things: print_icons.sh is using #!/usr/bin/bash which does not exist on my system. install.sh uses #!/bin/bash in comparison - I guess this was not intentional?

I had also tried ./install-autodetect.sh without high hopes, maybe you want to work around the declare message in the output below. It's questionable however whether a system with such old tools is worth supporting in the install step when the end result cannot work in the first place... I'll leave that decision up to you.

Detected terminals fonts:

- GNOME TERMINAL:
/home/colin/tools/icons-in-terminal/scripts/detect_font_terminal/find_font_gnometerminal.sh: line 10: dconf: command not found
No font found
- TERMINATOR:
No font found

IMPORTANT:
install-autodetect.sh is experimental
If your terminal isn't listed or if there is not your font, use install.sh instead
See https://github.com/sebastiencs/icons-in-terminal/issues/1

Font successfully installed. Now start a new terminal and run print_icons.sh :)

What terminal and shell are you using ? And which versions ? If you see the codepoints, it's because your shell doesn't interpret them (it is supposed to). The terminal should only support font fallback to make it work.

You can try https://github.com/sebastiencs/coreutils-icons to be sure that your terminal support it or not.

Thanks for the log I will look into it

GNOME Terminal 2.28.2 and GNU bash, version 3.2.57(1)-release running inside tmux 2.2. Running bash plainly in Gnome Terminal doesn't change things either.

[cmarqu]

FWIW, the first PS1 example in https://unix.stackexchange.com/a/25907 works, the second doesn't. So I guess I'd need at least bash 4.2.

[sebastiencs]

It seems that bash < 4.2 doesn't interpret utf 16, but it does with utf 8. I'm using utf 16 encoding in all the scripts

I ran bash 3.2.57 and I could print an icon with utf 8 encoding:

Can you try the same command ? echo -e '\xee\x83\xb1 '

Your example works when I use Konsole Version 2.3.3 Using KDE 4.3.5 (KDE 4.3.5) "release 0" but in GNOME Terminal, I get the square with "E0F1" in it. Actually, now that I try it in Konsole, print_icons.sh produces the nice icons! So it was a GNOME Terminal issue all the time?

[sebastiencs]

Glad to hear that. Yes this version of gnome terminal probably doesn't support font fallback
