[resotocore] Help text is hard to read in Ubuntu Terminal

[iainelder]

Description

In logs section I've pasted a text version of this screenshot.

The screenshot shows how the text renders with colors in Ubuntu Terminal.

The messages that start with hashes such as "# Show all available kinds." are almost impossible to read because the background is dark blue and the text is slightly darker blue.

Version

2.0.0a16

Environment

Ubuntu 20.04.3 LTS

Steps to Reproduce

1. Start an Ubuntu Terminal session.
2. Start resh using docker run.
3. Run a help command such as help kind.
4. Struggle to see the darker blue text on a dark blue background.

@iainelder thanks for the report. We need to take a look into the color scheme.
As a workaround for the time being: you can start the resotoshell with the --no-color option.

[aquamatthias]

I installed ubuntu and tried myself.

My terminal supports 256 colors. Above detail looks like this.

> echo $TERM
xterm-256color

Rendered with standard colors it looks like this:

which seems to be close to unreadable.

@iainelder What kind of terminal do you have (what is the TERM env set to?).

I would propose a change, which would look like this:

Standard:

256 Colors:

True Colors:

[iainelder]

I should add that I'm running all the resh commands in the Docker container version resoto:2.0.0a16.

@iainelder What kind of terminal do you have (what is the TERM env set to?).

In my Ubuntu terminal:

$ echo $TERM
xterm-256color

In the resoto Docker container:

root@e909714648ba:/# echo $TERM
xterm

If in the container I set TERM=xterm-256color then the output is more readable.

Does the default setting in the container need to be changed?

[aquamatthias]

Mmh typically the TERM variable should be set by the terminal emulator.
In case of docker, it will set the TERM variable to xterm (see environment-variables)
When exec into the docker container you can define env vars like: -eTERM - this will set the env var to the current value.

@lloesche any other idea?
