Pillar annotations for Latex
by Ben Coman May 24, 2014

May 24, 2014

The Pillar documentation [1] says... "An annotated paragraph starts a line with @@ followed by either todo or note. For example, @@note this is a note annotation. generates Note: this is a note annotation. And, @@todo this is a todo annotation generates a todo annotation that is not visible in the output." However this does not work when rendering to LaTex. * The notes do not start with "Note:" * The todos are visible This seemed to be handled by... PRMarkdownWriter>>visitAnnotatedParagraph: anAnnotatedParagraph "Pier seams to lack consistensy here ..." needsABreak ifTrue: [ canvas addInvisibleSeparator ]. anAnnotatedParagraph annotation asLowercase = 'todo' ifTrue: [ ^ self visitCommentedLine: anAnnotatedParagraph ]. self nest: [ :brush | brush name: '' with: [ :nestedStream | self writeRawDuring: [ nestedStream << 'Note: '. nestedStream << anAnnotatedParagraph text trimBoth ] ] ]. needsABreak := true. but that there is no equivalent PRLaTexWriter>>visitAnnotatedParagraph: and the following is used by default... PRVisitor>>visitAnnotatedParagraph: aDocument self visitParagraph: aDocument In seeking to fix this for LaTex I found... * /needsABreak/ is an ivar of PRMarkdown and I guess not applicable to LaTex * #nest: and the /nest/ ivar it references belong to PRMarkdown, and I'm not sure of their purpose. So I cut those out, which left the following... PRLaTexWriter>>visitAnnotatedParagraph anAnnotatedParagraph annotation asLowercase = 'todo' ifTrue: [ ^ self visitCommentedLine: anAnnotatedParagraph ]. self writeRawDuring: [ nestedStream << 'Note: '. nestedStream << anAnnotatedParagraph text trimBoth ]. ...which works well enough for the usage I see so far in PharoLaserGameTutorial. [2] Now is there any important function missing, or is there a better way to do this? I also want add an annotation type, which I'll describe in a following post. cheers -ben [1] https://github.com/pillar-markup/pillar-documentation [2] https://github.com/bencoman/PharoLaserGameTutorial

Initializing a class with a Dictionary
by sergio_101 May 23, 2014

May 23, 2014

is it possible to initialize a class with a dictionary? my first thought would be to create a method like: intializeWithDictionary: aDictionary then, loop through the elements and do something like: instVarNamed: key put: value but the book says: Caveat: Although these methods are useful for building development tools, using them to develop conventional applications is a bad idea: these reflective methods break the encapsulation boundary of your objects and can there- fore make your code much harder to understand and maintain.-- should i avoid this? ---- peace, sergio photographer, journalist, visionary #BitMessage BM-2D8VWUJSS41RFKh1ec83preVabHrnniExa http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.CodingForHire.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

[ANN] Pharo VM packaging for Ubuntu
by Damien Cassou May 23, 2014

May 23, 2014

Hi, I'm happy to announce a brand new packaging of the Pharo VM. The packaging works with all officially supported Ubuntu releases, both 32 and 64bits (see this list of Ubuntu support dates: http://en.wikipedia.org/wiki/Ubuntu_%28operating_system%29#Releases) I pushed these new packages to a different PPA so I can test without impacting current users : https://launchpad.net/~pharo/+archive/unstable/+packages If you are using an old version of Ubuntu (e.g., Precise 12.04 or even Lucid 10.04), you should try with this new PPA. Please report problems by email to me directly. An advantage of this new packaging is that it should become much easier to create Ubuntu packages for your own Pharo projects. I will talk about that later as I try these new packaging mechanism on the Launcher, Pillar and Phratch projects. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Student Volunteer Program ------------------------------------------------------------------------ If you are a student wanting to attend ESUG at Cambridge this summer, have you considered being a student volunteer? Student volunteers help keep the conference running smoothly; in return, they have free accommodations, while still having time to enjoy the conference.

Ghost Proxy
by FranÃ§ois Stephany May 22, 2014

May 22, 2014

What is the best way to load Ghost in Pharo 3.0? Is there a configuration somewhere? Is anyone using it? Voyage does seem to use the ProtoObject+dnu+becomeForward trick. Is there any reason for that?

A possible problem coming from Zinc?
by Usman Bhatti May 21, 2014

May 21, 2014

Hi, When turning on ZincFileLogger on a Zinc server, after some time (1h or so) I get the FileWrite error (see screenshot). I browsed through the bugs related to Zinc in the Fogbugz but couldn't find any bug related to my problem. I get the problem both on Mac (local machine) and Ubuntu (DigitalOcean instance) on Pharo 3.0 (release). This is my code to register logging on the server events: server := ZnMultiThreadedServer startOn: 4001. logger := ZnFileLogger onFileNamed: 'server-log.txt'. server log addListener: logger. Any pointers? tx. Usman [image: Inline image 1]

Unique identifiers
by Esteban A. Maringolo May 21, 2014

May 21, 2014

I would like to discuss alternatives for the generation of unique identifiers, in the context of URLs, database primary keys/no-sql keys, system interoperation, etc., etc. I used GUIDs in the past, which for simplicity I stored them in its string representation instead of using the byte/long representation. Do we have something other than UUID (16byte/36chars) to create identifiers? Does exist a shorter (ie. 8byte) UUID version? I know its uniqueness comes from the extra bits, but maybe a shorter display string can be used (as git commits does, but with 20 bytes) or directly less bytes like MongoDB's OID (12 byte). I'm thinking about unique identifiers in the context of different systems (and different languages), where datatype limitations can exist. E.g. Java's long is 2^64 -1, 8byte, SQLite can only store 8byte integers. So the most standard generator, least common denominator type would be the best approach. By now, the "least worst" solution I found is to keep using the 36 char string representation for persistence/serialization (JSON). But I'm sure there must be something else much more clever. What do you use for IDs? Regards, Esteban. Esteban A. Maringolo

observing Pillar execution (PharoLaserGameTutorial)
by Ben Coman May 21, 2014

May 21, 2014

The Pillar documentation [1] says the "@@note xyz..." should produce "Note: xyz..." but that doesn't seem to be happening. This seems to be handled in PRMarkdownWriter>>visitAnnotatedParagraph: but not in PRLaTexWriter. For the PharoLaserGameTutorial I invoke compile.sh. How can I similarly invoke Pillar but have it in GUI mode with a debugger so that I can learn about how Pillar executes? cheers -ben
