Ugh. How many beautiful projects have died because of Paragraph and
associated editors?!

A damn lot, I can tell you.��

This is where my vim keybindings experiment came
screeching to a halt.

What are the main problems with Text, Paragraph, ... and other old TextComponents?

Thanks Igor.

Maybe some more Info? (I don't have much experience with this and don't fully understand what is missing).

��

1. No support for vector graphics

I know some parts of Athens (with Cairo font renderer and how it is used in TxText) but at the moment

rendering a TextMorph in Athens works:
Morph comment asText asMorph openInSceneView

I don't see where the models (Text vs. TxText) is the problem.

��

2. Most operations are bound to text size.

In what use cases is this a problem ? (Paragraph and DisplayScanner have good support for justified text (left / right / center), indentation

wrapping and (I don't know if this works in pharo anymore but squeak had) even filling text in arbitary shaped polygons ( that was pretty cool).

And even for�� text of different size and with different emphasis.

��

��
And how are these solved with TxText?

��
1. By implementing new view, rendered by Athens

Ok ,but this could have be done (or is done) with the old Text class as well (no?)

��

2. By introducing new model for storing text to overcome mentioned limitations.

But this is exactly what I don't understand. How is storing the text in TxText model better than the old Text.

Given that we don't have any (beside TxWorkspace) tools actually using this model.

I have a faint idea how TxText could be easier for building advanced tools, but I don't see that this

model is a crucial point in developing good/better tools for text editing.
