Windows previewer / switcher

Hello,

This mail to announce you that I am working on a windows previewer / switcher for
Pharo [1].

It is still in early stage of development but it is usable.

To install it:

Metacello new
    repository: 'github://JulienDelplanque/WindowsPreviewer/repository';
    baseline: 'WindowsPreviewer';
    load

See the README for details on activation/shortcuts.

Please, if you have some ideas or critics let me know!

Also, a better name than “Windows Previewer” would be cool but I have
no other idea :-)…

Regards,

Julien

Functional callbacks on all Cog platforms

Hi All,

just wanted to report that as of Alien-eem.35 and https://github.com/OpenSmalltalk/vm/commit/da3fafdec9444754af104e0ed9f613f6eb1888d9 we now have functional callbacks on all x86 platforms, ARM32 platforms and x86_64 platforms.

There’s a simple example Alien class>>exampleCqsort that shows how to use the system and tests the implementation using the C library’s sort quick sort implementation that takes a function pointer as an argument to use for comparing pairs of elements. This is mapped onto a Smalltalk block by Alien’s callback implementation. The example sorts 100 random double-precision floats using qsort and a callback into Smalltalk.

New version of Interactive Fiction Framework

New version of Interactive Fiction Framework
(https://github.com/ericvm/smallworlds)

I think it is mature enough to be used, but of course there might be some
rough edges.

Contributors, users and testers would be very welcome!

Updated Pharo Launcher

Hi,

I just updated Pharo Launcher. A new version 0.2.11 is available.

Here are the change log:

move Pharo Launcher to the latest stable pharo image: pharo 5.0. It implies That Pharo Launcher is now shipped with Spur VM.
allow an easy download of the new beta image: pharo 6.0
the Launcher now comes with 2 VMs:
- Spur VM (pharo 5.0 and Pharo 6.0)
- Non-Spur VM (to be able to run old images)
the Launcher is now shipped with a default template that is the current default Pharo image. It can be found in local templates.
there is a new OS bundle for linux: we now ship more files with the launcher and it was needed to have a bundle.
update of the default name propose when you create an image from a template: the default name will be the project name.

If you want to give it a try, executables are there:

Christophe.

Automatic Deprecation Refactoring

Hi,


I have dusted off and improved the automatic refactoring of deprecations.

- when the refactoring engine is not present, it falls back to a standard deprecation
- It does not introduce any dependencies (can just be in the Kernel, the only cost is one method of 10 lines).
- It sets the author so it does not require initials
- It refactors *only* the sending (offending, deprecated) send site. So a second selector that is identical (which might be a different method and not deprecated) will not be affected.

The way to use it is this:

ifNotNilDo: aBlock
    self
        deprecated: 'Please use #ifNotNil: instead'
        transformWith: '`@receiver ifNotNilDo: `@statements' -> '`@receiver ifNotNil: `@statements'.
    ^ aBlock ifNotNil: aBlock


As we try to provide already Lint rules for deprecations (or at least should have..) the amount of additional work is not much.

This is the full implementation:

deprecated: anExplanationString transformWith: aRule
    | rewriteRule method context node |
    context := thisContext sender sender.
    (Smalltalk globals hasClassNamed: #RBParseTreeRewriter) 
        ifFalse: [ ^self deprecated: anExplanationString ].
    method := context method.
    node := context sourceNodeExecuted.
    rewriteRule := (Smalltalk globals classNamed: #RBParseTreeRewriter) new replace: aRule key with: aRule value.
    (rewriteRule executeTree: node)
        ifFalse: [ ^ self ].
    node replaceWith: rewriteRule tree. 
    Author 
        useAuthor: 'AutoDeprecationRefactoring'
        during: [method methodClass compile: method ast formattedCode classified: method protocol]

https://pharo.fogbugz.com/f/cases/18507/

This is *with intention* the absolute “simplest thing that can possibly work”. There is no interactive tool to preview refactoring in interactive
mode, or some way to opt in or out. 

The power of things like this comes from actually using them, not from being perfect...

Nicer haltOnce

Hi,

Yesterday we improved #haltOnce to be more like a “once” BreakPoint:

	-> state per *each* haltOnce send
		(this means you can put two in one method and they are independent)
	-> when putting a haltOnce, it is enabled by default
	-> The global menu entry just resets all haltOnce to be active again.

Interesting is how trivial this was to implement… in class Halt 
once
    | node |
    node := thisContext sender sender sourceNodeExecuted.
    (node hasProperty: #haltOnce) ifTrue: [^self]. 
    node propertyAt: #haltOnce put: true.
    ^ self signal.


This means, we get the AST node of the “haltOnce” message send. Then we put an annotation there.
To reset all (enable all), the global many just does:

	#haltOnce senders do: #recompile.

Done.

This will be in 60082.

PassBy[ME] lib for Pharo

Hi,

I made a library for an online 2 factor authentication service called 
PassBy[ME] <http://passbyme.net>  . 

This a service that provides PKI based 2nd factor authentication (using
smartphones) among other things like message sending and electronic
signatures.

The library lets you start new authentication sessions and send messages to
the user's phone.
