[Pharo-project] [3.0] update 30061 needs a fix

by Marcus Denker

-> if you have already 30061, the attached file in fixes it -> I added this code to be loaded directly with the 30061 update and have triggered a rebuild on jenkins. So all is good againâ¦

Re: [Pharo-project] Rubric questions :)

by plantec

Hi Sean, I come back to Pharo after one year â¦. So, I did'nt known anynothing about TxText. Now, I've read some posts about it and it is a very exciting project but nothing to do with Rubric, I mean, no relationship between the two projects. The mains goals of Rubric are to improve the existing infrastructure for text editing, to improve performance for (very) big texts and to make the infrastructure more easily extendable. So maybe something that will be thrown away when projects like TxText will be mature and enough efficient. Anyway, I will have a look at TxText to learn more.
