required packages about bash-oo-framework HOT 5 OPEN

Maybe this helps?

from bash-oo-framework.

i do get colors using

$ python -c "print('\033[91mtest\033[0m')"
test

there is really no text underneath the overementioned message.

from bash-oo-framework.

actually, @tterranigma the post had some right ideas. I added the following:

USER igor
# activate color terminal
ENV TERM xterm-256color
RUN sed -i -e 's/^#force_color_prompt=[^\n]*/force_color_prompt=yes/' ~/.bashrc

sourceing ./basrc at run-time after editing is not enough for bash-oo-framework. setting TERM in run-time user environment is also not enough.

Has there been no requirement yet for non-colored terminals? I would have expected pure text-output if no color is activated.

We do have color mode detection. No colors should be displayed when we detect a terminal without support for colors:

Perhaps that line doesn't work under Docker. Happy to accept PRs that fix this!

Thanks for investigating. Related issue #19

from bash-oo-framework.

with ENV TERM xterm-256color

$ echo [ $(tput colors 2>/dev/null || echo 0) -ge 16 ]
[ 256 -ge 16 ]

without setting any ENV:

$ echo [ $(tput colors 2>/dev/null || echo 0) -ge 16 ]
[ 8 -ge 16 ]

I don't understand the second part but it resolves to true

$if test -t 1; then echo 1;fi
1

So it seems, standard docker containers get 8 colors. Is 16 colors really a minimum requirement here?
