[FYI] Athens tutorial

Hello, there

i prepared a small tutorial for Athens, which i did today at PharoConf.
But the code i did can be reused by non-participants of conference :)

Here the instructions.

Download Pharo 2.0

wget -O - get.pharo.org | bash

Run Pharo 2.0

./pharo-ui Pharo.image

In a workspace, evaluate (line after line)

Gofer it smalltalkhubUser: 'Pharo' project: 'Athens'; configuration; load.

ConfigurationOfAthens loadVersion: '2.0'.

Gofer it smalltalkhubUser: 'Pharo' project: 'Athens';
package:'Athens-Tutorial'; load.

AthensTutorial new openWithSpec.

Took from here
https://gist.github.com/SergeStinckwich/44ca34b54cde83b687a3
(just removed duplicates ;)

Thanks, Serge for compiling it down ;)

Once you load the code and have window open, skip step one (you already did it),
and then just follow the steps by pressing doit button changing the
code , pressing doit again , going forwards etc .. and playing with
it.
I put some comments there to serve as a small description/detail.

Any feedback & help & contributions & improvements is welcome.

P.S. if you get a DNU at step 30, enable Freetype in settings and try again.

Hi,

Indeed, we just followed this tutorial at PharoConf, and it is well made.

Thanks, Igor.

Really nice :) That was my first time using the zero conf scripts... very slick :) And the tutorial was extremely clear and thorough. This active essay embodies the dynabook spirit.

I added a "The end" page and a little edit to prevent stepping past the last page. No repo access, attaching to Nabble... Athens-Tutorial-SeanDeNigris.2.mcz

In reply to this post by Igor Stasenko

Hello,

I am on Ubuntu 12.10 32bit.

I have followed the directions below for the Tutorial.

After the bash script completed it gave me these instructions.

Please install the 32bit libraries
sudo aptitude install ia32-libs

I typed the above into the terminal and was told that I do not have
"aptitude" installed.

I changed "aptitude" to "apt-get" and then was instructed that I do not
have ia32-libs.
I went to the Ubuntu Software Center. What is on Ubuntu 12.10 is
ia32-libs-multiarch.

sudo apt-get install ia32-libs-multiarch works.

I then open the image and proceed with loading the code and the tutorial.

I skip page 1 and "doit" on page 2 and I get this error.

Error: failed to get a symbol address: cairo_image_surface_create

As far as I can tell, I have Cairo installed on my system. I have libcairo2.

I don't know if I am missing something or what I need to do.
I haven't successfully done anything that I am explicitly aware that
used NB that has worked on this system.

I have just a standard Ubuntu 12.10 32bit install. I have the
build-essential libraries.

Just wanted to provide some input.

Let me know if there is something I need to install or what I can do to
help.

Jimmie

aptitude is old (some kind outdated) and I have had several problems with it.
we should always recommend to use apt-get instead :)

Thanks, that was the problem.

On Ubuntu 12.10, I don't have a libcairo.so, but rather a libcairo.so.2
in /usr/lib/i386-linux-gnu.

I created the link /usr/lib/libcairo.so as expected by Pharo, and it works.

Now, when I get to screen 30, I enabled FreeType as instructed but I am
getting an error
MNU: StrikeFont>>glyphRenderOn:

Thanks again.

Re: [FYI] Athens tutorial

Same error here on OSX. I guess it is because we need to use the FreeType fonts instead of the default StrikeFonts.

Re: [FYI] Athens tutorial

I had already enabled Freetype as instructed in the email.
So I went ahead and then changed the StandardFont to FreeSans 9 and did Force all.
Still did not work. I saved and quit. Restarted and tried again and it worked.

I don't know if FreeSans is the best font choice or not, just simply the one that I tried.

Yes, Athens does not supports StrikeFont(s). Because they are not scalable and
more than that, they using precomputed subpixel bitmaps, which assuming that
your font will always match the pixel grid, which in case of
scaling/rotating of course will not.

Very cool tutorial :)

I show it at my works and they are impressed of the readability of Athens!

Juste a remark about the text.

I try to rotate the text and (I d'ont know if it's the good behavior). All the text rotate but the letter not.

Hello, there

i prepared a small tutorial for Athens, which i did today at PharoConf.
But the code i did can be reused by non-participants of conference :)

Here the instructions.

Download Pharo 2.0

wget -O - get.pharo.org | bash

Run Pharo 2.0

./pharo-ui Pharo.image

In a workspace, evaluate (line after line)

Gofer it smalltalkhubUser: 'Pharo' project: 'Athens'; configuration; load.

ConfigurationOfAthens loadVersion: '2.0'.

Gofer it smalltalkhubUser: 'Pharo' project: 'Athens';
package:'Athens-Tutorial'; load.

AthensTutorial new openWithSpec.

Took from here
https://gist.github.com/SergeStinckwich/44ca34b54cde83b687a3
(just removed duplicates ;)

Thanks, Serge for compiling it down ;)

Once you load the code and have window open, skip step one (you already did it),
and then just follow the steps by pressing doit button changing the

Re: [FYI] Athens tutorial

Yes, this is a known bug actually, which i demonstrated to audience during
tutorial presentation..
i/cairo miss the correct font matrix setup.. and i need to see what's there.
Cairo caching the glyphs in a strange way (so if you never drawn
anything with given font before and your first drawing will use some rotation
then everything will be rendered correctly, but if you already drawn anything
it will render them like you shown)..
I'm going to fix that issue when i come back from Lviv.

i prepared a small tutorial for Athens, which i did today at PharoConf.
But the code i did can be reused by non-participants of conference :)

Here the instructions.

Download Pharo 2.0

wget -O - get.pharo.org | bash

Run Pharo 2.0

./pharo-ui Pharo.image

In a workspace, evaluate (line after line)

Gofer it smalltalkhubUser: 'Pharo' project: 'Athens'; configuration; load.

ConfigurationOfAthens loadVersion: '2.0'.

Gofer it smalltalkhubUser: 'Pharo' project: 'Athens';
package:'Athens-Tutorial'; load.

AthensTutorial new openWithSpec.

Took from here
https://gist.github.com/SergeStinckwich/44ca34b54cde83b687a3
(just removed duplicates ;)

Thanks, Serge for compiling it down ;)

Once you load the code and have window open, skip step one (you already did it),
and then just follow the steps by pressing doit button changing the
code , pressing doit again , going forwards etc .. and playing with
it.
I put some comments there to serve as a small description/detail.

Any feedback & help & contributions & improvements is welcome.

P.S. if you get a DNU at step 30, enable Freetype in settings and try again.

Yes, this is a known bug actually, which i demonstrated to audience during
tutorial presentation..
i/cairo miss the correct font matrix setup.. and i need to see what's there.
Cairo caching the glyphs in a strange way (so if you never drawn
anything with given font before and your first drawing will use some rotation
then everything will be rendered correctly, but if you already drawn anything
it will render them like you shown)..
I'm going to fix that issue when i come back from Lviv.

Super :)

Did you also see the cairo_text_path() method? It's very interesting if you want to stroke the letter!

Very cool tutorial :)

I show it at my works and they are impressed of the readability of Athens!

Juste a remark about the text.
I try to rotate the text and (I d'ont know if it's the good behavior). All the text rotate but the letter not.
