Printing in transcript inside a loop

Hi all,

I want to print in the transcript from inside a loop, the problem I am seeing is that it does not print until the loop is finished. Is it a bug or do I have to configure something?

This is a piece of code to exemplify it

(1 to: 10000) do: [ :i |

Transcript show: i asString.

]

Thanks in advance

By the way, I am using Pharo 3.

Hello,

You need to fork it to be able to see the updates right away.

An example :

[ 1 to: 100 do: [ :i |
Transcript show: i asString.
(Delay forMilliseconds: 20) wait.
] ] fork

Cheers,

Matthieu

Or ask for the world to happen if the code is in the UI thread.
