Hi, after setup, not able to start.

Thanks.

Exactly the same here.

that particular import still works with textual==0.85.0 - but fails starting with 0.86.0.

odd that it wasn't mentioned in release notes ... but textual itself seems to be quite in flux - maybe we should hard-pin it to avoid such failures?

[froggleston]

This is down to the Textual library changing from the previous theming system to a new one. The plotext library hasn't been updated to reflect this core change, but a PR is open: Textualize/textual-plotext#14

This should work for now: 60a8701

Perfect, thanks guys for the quick update.

It worked.

[darrenburns]

You should pin Textual, as it's still zerover and so the API is subject to change.

We'll be hitting 1.0.0 soon, and then trying to adhere to SemVer as much as possible.

We've just released a new version of textual-plotext, which hopefully resolves the issues.

Awesome, thanks for the info @darrenburns !

Thanks! it works, but now complains about this:

AttributeError: 'Plot' object has no attribute 'datetimes_to_string'

[darrenburns]

@jisnardo Did the Plot class previously have that method? Don't recognise it.

[froggleston]

If using the newer plotext version, yes, that function has been renamed: #9

So we're at a bit of an impasse. I'll need to properly address both issues.

@jisnardo what are your package versions? I've just tried with textual 0.85,0, plotext 5.2.8 and textual-plotext 0.2.1 and it seems to work?

[jisnardo]

plotext is 5.3.2 instead of 5.2.8, that causes de issue, just downgrade and works
