you can change the size of the image using |width=60| it is expression
is given in %
I fixed it. I will read it and give you feedback.
Now I just skimmed throw it and I would
- structure the text with some sections like setup, importing,
computing, rendering, conclusions
- then I would turn the large roassal script in a tiny and beautiful class

Stef, thanks for adding me to the repo. I've plugged my blog post in as chapter
1.

On Pillar, I see that the generated PDF shows the array inspector screenshot as
an outsized image. What's the best practice on sizing images?

Anyhow, I've set up Docker with the texlive:pillar image and just did a
successful test run. I can now experiment with agility. :-)

Re: [Pharo-users] Roassal to ODG

[Peter Uhnák]

There is SVG exporter.

I've never heard about ODG, is it commonly used outside of OpenOffice
itself?

[Pharo-users] cancel changes in Nautilus broken on 6.1?

[Siemen Baader]

Hi all,

I downloaded Pharo 6.1 for OSX and whenever I revert changes in Nautilus
with CMD-L, the content is reverted and the orange dirty marker triangle
disappears. But when I switch to a different method, Nautilus shows the
'Content has been modified. What do you want to do?' dialog, as it only
should when content is actually different.

I use this all the time, I can't imagine I'm the only one, but I couldn't
find the problem mentioned anywhere. Does anyone else have it? What to do?

[Pharo-users] Roassal to ODG

[Arturo Zambrano]

Hi all,
 Is there any project for exporting Roassal to ODG (vector graphic format
from open document format standard)? The closest thing I could find is
RTPDFExporter (the generated PDF can be opened using (Libre/S/G)Office
suite).

If there no such exporter, how difficult should it  be to build one,
compared to RTPDFExporter?

 TIA
Arturo

I will add it to Calypso.

 The refactoring browser is already capable of generating #= and #hash:

Thanks all,

I’ll give a try to roassal so.

It should still be part of Roassal, with some issues with the data
sources used to retrieve cities coordinates (they went offline!).

I haven't started working with Pharo 7 yet, so I can't say.
