tab width too small about alexandrie

[tinchodias]

I realized that Sparta doesn't align but only replaces tab character by 4 spaces (see Character>>#textRunOn:).

Rubric does align:

Code:

stringWithTabs := '
A	A
AA	A
AAA	A
'.

RubEditingArea new
	font: (LogicalFont familyName: 'Source Sans Pro' pointSize: 20);
	updateTextWith: stringWithTabs;
	tabWidth: 100;
	openInWindow.
	
editor := AlbEditor new
	text: stringWithTabs asRopedText;
	yourself.
space := BlSpace new.
space root addChild: editor.
space show.

Debugging I see:

the editor has a current paragraph, then:
a paragraph has a RubTextComposer
--> a RubTextComposer has a TextStyle
----> TextStyle uses TextConstants
------> TextConstants defines DefaultTabsArray as #(24 48 72 96 120 144 168 ... 936 960)
and that's the default tab stops.

I wonder if our editor has equivalent text style and composer.

Pango seems to implement it similarly, you can just set a default tab width, or set an array of tab stops:
https://docs.gtk.org/Pango/struct.TabArray.html

btw, I've found interesting this elastic tabs, but didn't try it:

Do you think we can fix this more correctly like in Rubric? or it could be an easy workaround to do like Sparta, do a pass before rendering and convert each tab to certain number of spaces.

Character>>#textRunOn: ... :))
rrrrrrahhhh, shitty, could have seen it by myself

yes, Rubric handles tab a much clever way. I will think about that. it should be possible to change that.
Thanks, this is an Album issue now.
Regarding elastic tab: interesting, I will see how to allow such a feature in the futur

I will close this issue, as Alain fixed it.

text := stringWithTabs := '
A	A
AA	A
AAA	A
' asRopedText.
text onAlbum openInOblSpace.
