## Multiple Desktops for Pharo

Julien Delplanque provided this week a goodie to switch between
"desktops" - but his initial solution was more or less hiding windows
and not really switching between real Pharo worlds/desktops.

I gave him some tips what could be done on the pharo-user list. Havent heard
from him afterwards.

Now I was able to spend a few hours on this topic myself and implemented
a full multiple desktop solution myself.

This works in Pharo 5 only (currently) and requires latest VM (at least on Windows)
from files.pharo.org to get the keyboard shortcuts right.

To try:

Gofer new
smalltalkhubUser: 'TorstenBergmann' project: 'DesktopManager';
configuration;

integration and even a custom spotter with preview of the desktops.

Quick start:
===========
- evaluate the above expression in a Pharo 5 image
- check the world menu "Desktop"
- you can press CTRL + D and then CTRL + A (= Desktop Add) to add a new desktop
- you can press CTRL + D and then CTRL + D (= Desktop Desktop) to open the overview
- you can press CTRL + D and then CTRL + P (= Desktop Previous) to navigate to the previous desktop
- you can press CTRL + D and then CTRL + N (= Desktop Next) to navigate to the next desktop

The code is hopefully a good example on how to build a custom spotter, shortcuts, inspector extensions, ...
Additionally all this is described in a new article including screenshots
and a guide on how to use this new goodie:

https://medium.com/@astares/multiple-desktops-for-pharo-5cbc46f3179f

Actually the article took more time to write than coding but I hope
it helps explaining Pharo and why it is a power tool.

Project is on http://www.smalltalkhub.com/#!/~TorstenBergmann/DesktopManager
Article and code is still subject to change.

Have fun

## Ephemeric Cloud to a MongoDB hosted at Digital Ocean

Hello,

Good news everyone! :)

Today I have successfully connected an application published in
Ephemeric Cloud to a MongoDB hosted at Digital Ocean!

http://eph-f2e2bcac.swarm.pharocloud.com/todo

It became possible due to a stunnel support implemented in Ephemeric
Cloud runtime – the utility allows to create secure tunnels between
applications. Thus the communication between an ephemeric instance and
a droplet is encrypted and safe. Configuration is extremely simple –
just put a stunnel.conf and the certificate files to your Image
archive before publishing it.

This approach is universal and it allows to connect Pharo Images to
any service providers or dedicated servers. Therefore Ephemeric cloud
becomes more than just Pharocloud but an universal tool to develop and
publish Pharo web applications. Another good thing is that it has a
free tier :)

Please try it out and tell me what you think.

You can find some documentation here:
https://www.pharocloud.com/kb/tutorial/connect_ephemeric_to_digital_ocean

Cheers,
Mike

## Phratch 4.1

Based on Phratch 4.0 we made some bug fixes and added new small features. Phratch is now on top of Pharo 4.0.
The new features are:
– languages are more stable. Thanks to the community for the feedback and the enhancement of the language files.
– Add a “follow” option that allows one to see which block is currently executed.
Phratch 4.1 is already available on phratch.com.
If you detect an issue, you can submit a description on https://github.com/janniklaval/phratch/issues
And you can always download the latest build on the continuous integration server: https://ci.inria.fr/pharo-contribution/view/Phratch/
See you on phratch.com

## “pharo get” to load catalog published software

Hi,

This functionality is in fact in Pharo 5 since a couple of months (I added it during ESUG), but I forget to send the ANN, then probably people does not know it and then is not using it.
This is a catalog command line handler to prepare your images from command line. For example, if I want an image with Seaside3:

./pharo Pharo.image get Seaside3

or if you want a version:

./pharo Pharo.image get Seaside3 —version=3.1.2

since this tool is part of catalog, just catalog projects are available… but I find it very useful for prepare my images (and a lot less verbose than the config command line who is still available for non-catalog projects)

cheers,
Esteban



## New Tool: Flow message browser

A new tool to browse and dive deep into the flow of messages
using a tree representation (messages, senders, implementors, ...)
and further on. I know such a tool from Smalltalk/MT and it is really
helpful to trace a message flow without running in the debugger.

See the attached screenshot, the best is to try it:

In a latest Pharo 5.0 image (Pharo5.0 Latest update: #50314)
you can evaluate:

Gofer new
url: 'http://smalltalkhub.com/mc/TorstenBergmann/MessageFlowBrowser/main';
package: 'Tool-MessageFlowBrowser';

Then open whatever method in Nautilus and choose "Message Flow" from the context
menu. The nice thing is that you can dive into senders, implementors, messages sent
deeper and deeper (or up again) and you do not open more and more windows but stay
in a single window !!!

Alternatively you can start the tool from the playground:

MessageFlowBrowser openOn: #inspect "open the flow browser on a selector"

MessageFlowBrowser openOn: (Compiler>>#evaluate) "open the flow browser on a method"

MessageFlowBrowser openOn: Object   "open the flow browser on a class"

1 messageFlow.                      "open the flow browser on the class of an instance"

If someone with GT knowledge and time could help to correct the syntax highlighting
in the code pane this would be super cool (see method MessageFlowBrowser #openOn:).
Also selection could be improved to show/highlight the messages sent directly
in the code. Unfortunately I'm not so familar with the current code editors - so
any help is appreciated.

Repo is open for contribution.

Thanks
T.

Low traffic announce-only list for Pharo and related news:

## Pillar 1.0.0 is out

Hello guys!

I finished 5 months of internship into the RMoD team. I worked on Pillar
and I am glad to announce the version 1.0.0!
You can find an updated documentation of this version here :
https://ci.inria.fr/pharo-contribution/view/Books/job/EnterprisePharoBook/lastBuild/artifact/book-result/PillarChap/.

We decided with Damien Cassou to use Semetic Versioning from now (see:
http://semver.org/).

I will now explain the main changes I did on Pillar during my internship.

For each new feature I added tests and documentation.

I will begin with the changes of Pillar's structure

- The configuration system is now manage by Cocoon
(http://www.smalltalkhub.com/#!/~PharoExtras/Cocoon)
-- We now use Magritte in Cocoon

- I added Annotations : A syntax extension point

- I added Transformers : A way to transform a document model before an
export (to add a section structure in HTML for example)

- Some small refactoring.
-- Improvement of the template management
-- Improvement of the Pillar model parameters

- Improvement of the document model
-- Now the figures and links are two different entity

- I begun a PetitPillar (with PetitParser) in order to replace the old
parser too complicated.

Now I will talk about new features for the users

- Improvement of the usability of Pillar under Windows

- Beamer and Deck.js exporters

- Annotations :
-- To include a Pillar file into an other (${inputFile:path}$) (Example:
https://github.com/SquareBracketAssociates/EnterprisePharo/blob/master/EnterprisePharo.pillar)
-- To create new slides in Beamer and Deck.js (${slide:My Title|label=optional}$)
-- To create columns into a Pillar document (currently works in Beamer,
Deck.js and HTML)
-- …

- Transformers
-- You can now add a parameter "lineNumber=true" to a script and Pillar
will transform them to add the line numbers
-- You can now import a script from an other file (see the documentation
of the scripts)
-- …

- Improvement of the errors raised by Pillar

- Improvement of the title configuration for numbering

- No need to make scripts anymore to use Pillar !
-- You can used "defaultExporters" in your configuration to do multiple
export (see documentation)
-- Pillar generate a script for LaTeX compilation (only for Unix for now)

- Possibility to export everything into a different folder (simpler to
clean after)
-- And possibility to copy some support files

For the two previous point you can take example on Enterprise Pharo
(https://github.com/SquareBracketAssociates/EnterprisePharo) and Pharo
Mooc (https://github.com/SquareBracketAssociates/PharoMooc).

This was a really cool internship :)

If you have some questions do not hesitate!
