Feature Request: syntax highlighting #63

Open juarezr opened 4 months ago

Hi,

Do you have any plans for supporting syntax highlighting in the widget?

There are some crates that could help, but I don't know if there is interest in having syntax highlighting as a feature.

YES PLEASE

Or at least it would be great to have the possibility to use TextArea with ratatui's Line, since we can color the Spans inside ourselves

I think this would be awesome to have, I'm writing a code editor right now and well syntax highlighting is a key feature of every code editor. I hope someone works on this.

I am doing kind of the same thing and I succeed to apply Syntax highlighting on a Vec of Line into a Paragraph using Syntect. But since the TextArea does not work with a Vec of Line, it's incompatible...

(After digging a little the component, it is rendered by transforming the String to a Vec of Line and putting into a Paragraph. So we might not be that far)

Hello guys!

I tried to make a fork and do a quick implementation. Everything works great until you have a tab. The lib creator has put some mechanism to replace \t by some spaces (according to widget tab_len property) only in the text representation. It increments the line length but not the actual text length. I can't get to fix it.... It took me about 5h to do this and I don't to play with it anymore to keep some sanity

Here is the link of my fork: https://github.com/Julien-cpsn/tui-textarea

If you wish to correct this problem, it would be greatly appreciated!!!!
