Nice! You can set :color => true here

Pluto.jl/src/runner/PlutoRunner.jl

Line 923 in d05bccc

const default_stdout_iocontext = IOContext(devnull, :color => false, :limit => true, :displaysize => (18, 75), :is_pluto => false)

to tell Julia packages that they can write to stdout in color.

Can you also make a screenshot of Crayons.jl?

[HirumalPriyashan]

Seems we are losing underline, bold etc.

Nice! Looks like we were using AnsiUp incorrectly, which is why the second cell in your screenshot was shown in red (this state was remaining after rendering the first cell). I added a commit to fix that

[fonsp]

Maybe #2088 next? :)

@fonsp
Let's update ansi_up version too.

Pluto.jl/frontend/editor.html

Line 29 in d1ebade

<script src="https://cdn.jsdelivr.net/npm/ansi_up@5.0.1/ansi_up.min.js" defer></script>

@v5.1.0 supports underline, italic as well.

oh heck this is cool!

[fonsp]

Oooh awesome, lets do that!

Is this meant to work with regular show text/plain output now? I notice say DimensionalData.jl output is coloured in the REPL but single color in Pluto.jl, losing a lot of useful information.

@rafaqz Could you post a MWE?
