TeXworks ⇒ run sage from texworks

[aj_]

Hello guys,

thank you very much for the great work you are doing in this forum.

I got the following problem.

I installed sage and sagetex.
I can use it if I
1. run pdfLatex in texworks
2. go into the terminal and run sage over the created file.sagetex.sage
(sudo sage file.sagetex.tex)
3. run pdfLatex in texworks

Now I want to do this with one click/key in texworks.
I already found these two pages and tried it. But it does not work:
https://github.com/dandrake/sagetex/wiki
http://www.highschoolmathandchess.com/p ... ther-ides/

Does anybody know how to do it?
How can I tell texworks to run sage?

Thank you very much for your help.
greetings
