Loading Glorp+PostgreSQL
by Sven Van Caekenberghe May 27, 2017

May 27, 2017

I am bringing my Reddit example back up to date (https://medium.com/concerning-pharo/reddit-st-in-10-cool-pharo-classes-1b53…) for an upcoming Pharo Booklet. I used to depend on and load Glorp+PostgreSQL in my Configuration as follows: spec project: 'Glorp' with: [ spec className: 'ConfigurationOfGlorp'; versionString: #stable; repository: 'http://www.smalltalkhub.com/mc/DBXTalk/Configurations/main' ]. spec project: 'PostgresV2' with: [ spec className: 'ConfigurationOfPostgresV2'; versionString: #bleedingEdge; repository: 'http://www.smalltalkhub.com/mc/PharoExtras/PostgresV2/main' ]. spec package: 'GlorpDriverPostgreSQL' with: [ spec repository: 'http://www.smalltalkhub.com/mc/PharoExtras/PostgresV2/main'; postLoadDoIt: #postLoadGlorpPostgresNativeDriverDBXTalkPharo; requires: #( 'Glorp' 'PostgresV2' ) ]. This works fine in Pharo 6 now. My first question is, is this the 'correct' way of loading Glorp+PostgreSQL ? Do I get the latest, maintained code this way ? My second question is, why is #stable not available for Pharo 6 for PostgresV2, what should be done to fix this and could someone add it ? Thx, Sven

Deploying a Pharo Application (non-web)
by horrido May 26, 2017

May 26, 2017

Everybody seems to be pointing to this (apparently out-of-date) page: http://squeakvm.org/win32/custom.html <http://squeakvm.org/win32/custom.html> . However, I cannot find the settings for /warnIfNoChangesFile/ and /warnIfNoSourcesFile/ in Pharo 5.0 in the Settings Browser. Where are they buried? -- View this message in context: http://forum.world.st/Deploying-a-Pharo-Application-non-web-tp4948400.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Ston feature idea?
by Cyril Ferlicot D. May 26, 2017

May 26, 2017

Hi! At Synectique sometimes we use Ston to export models that contains some MooseEntities. Moose entities been complex, we usually export only the moose name of the entity then we retrieve the entity during the import. But we did not find any "easy" way to do this in Ston. I used voyage and it has a system like this. Example: Amount class>>mongoCurrency <mongoDescription> ^ VOMongoToOneDescription new attributeName: 'currency'; accessor: (MAPluggableAccessor read: [ :amount | amount currency abbreviation ] write: [ :amount :value | amount currency: (Currency fromAbbreviation: value) ]); yourself With this Voyage know how to read/write the instance variable "currency". I think it would be cool to be able to easily customize import/export variables with Ston. Maybe it is already possible but I missed the way to do it? I would like your thoughts about that. :) -- Cyril Ferlicot https://ferlicot.fr http://www.synectique.eu 2 rue Jacques PrÃ©vert 01, 59650 Villeneuve d'ascq France

Booklet update
by Stephane Ducasse May 25, 2017

May 25, 2017

Hi There are 7 booklets on the back burner Smacc, Voyage, Mocking, Bloc, Reddit, uFFI, Glorp and more to come. My goal is to flushmy hard-disc and make sure that other people can contribute. Now I made sure that all have a travis green job! Thanks a lot to damien P for the docker latex package. It is great. I also created jenkins jobs (some are failing but this is a slave problem to me). So now you can contribute and see you changes integrated. Stef

mustache questions
by Stephane Ducasse May 25, 2017

May 25, 2017

Hi Norbert Pillar uses Mustache: it generate a json file and take the template and ask mustache to do the inlining. Now I just hate the idea that we have objects that we should save in file to produce other files... Do you know if we could use mustache directly: i.e., get the text from object, get the template and inject it directly without saving to json files, loading from json files.... Stef

What happened to Pharo 6. Postponing is understandable while not dropping a note about it, is not. What is the next best release date? Or did I just miss something? Norbert

A benchmarking package or lib ?
by Steven Costiou May 25, 2017

May 25, 2017

Hi, is there any benchmark library for Pharo ? that would provide tools to choose metrics to measure between two versions of the same code and maybe display a comparison or something (whatever the form of the report) ? I've found BenchmarkResult in Pharo but it seems very basic, at least there are no detailed examples of how it could be used. I'm specifically looking for a way to measure the speed of method calls (if that is possible) or the memory usage, but i'm also curious in general about what is measureable and try different benchmarks to see the results. So if there were a tool already doing all this work... ? Steven.

How to add a contextual menu to a Spec ListModel
by Sven Van Caekenberghe May 25, 2017

May 25, 2017

Hi, I am struggle a bit in find the right way to add a contextual menu to a Spec ListModel. Consider: ListModel new title: 'List Example'; items: Smalltalk allClasses; openWithSpec. I would like to add a right-click contextual menu to the list, with for example a 'Browse' action. I can't find such a simple example. I know there is a #menu: option, I can see some usages in my image, but they seem to do different things. What would be the recommended approach ? ListModel new title: 'List Example'; items: Smalltalk allClasses; "menu: [ ];" openWithSpec. Thanks, Sven PS: Probably the reference to the #selectedItem of the ListModel for the action is hard to write in a one-liner, that is not a requirement.

Re: [Pharo-users] How to query a JSON
by Stephane Ducasse May 25, 2017

mark what you can also do is to generate the classes from the json we did that for certain libraries.
