Re: [Pharo-users] [ANN] SETT (Store Export to Tonel Tools) for Pharo6.1

by Esteban Maringolo

Hi Dale, The issue I faced was a trivial one, but also easy to miss. I installed a vanilla linux environment to run it, and git was not initialized, so I needed to config the user.name and user.email global settings. So every time Sett executed `git` it was complaining about the missing config. In the docs it talks about Rowan, but I couldn't spot what is the Rowan part in the repo, other than the "rowan" directory itself. There aren't any Rowan related classes in the image. Esteban A.

Re: [Pharo-users] RBPattern syntax

by Manuel Leuenberger

Hi Henrik, Thanks for the the link. Interestingly, I was presented the same page on an old version, https://web.archive.org/web/20090227160738/http://st-www.cs.uiuc.edu/users/… <https://web.archive.org/web/20090227160738/http://st-www.cs.uiuc.edu/users/…>. Good to see, that there is still a maintained source. As for the rule you presented, that is pretty cool, you got way closer to the goal than I did. John Brant mentioned that these kind of matches/transformations are not easily supported by RB by design, especially cascades seem to be problematic, as well as sequenced/nested message sends. I am now looking into the RewriteTool (http://smalltalkhub.com/#!/~MarkRizun/RewriteTool/commits <http://smalltalkhub.com/#!/~MarkRizun/RewriteTool/commits>) and Phorms (http://smalltalkhub.com/#!/~CamilleTeruel/Patterns/commits <http://smalltalkhub.com/#!/~CamilleTeruel/Patterns/commits>), which seems to have a more powerful pattern matching language.

I think with your background/experience, it comes down mostly to your own preferences. What do you like to use (SQL or not) ? How much assistance do you need (object mapper or not) ? There are also https://github.com/svenvc/P3 (a newer PostgreSQL client). http://books.pharo.org/booklet-Voyage/ (non-SQL) http://books.pharo.org/booklet-Glorp/ (Object Mapper) ... > 3) There is any documentation about deployment and maintenance for a Pharo + > Seaside app ? > I have found "2016-10-06-EnterprisePharo.pdf" but may there are other > sources... Here too, you have many options, depending on style/experience. Like you said: There is https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… ? You can also study this https://github.com/svenvc/pharo-server-tools In any case, this is a solved problem (apart from session sharing, but you can get far with session affinity).

That is already provided, you should implement SQOne class>>#stonName ^ #OneChoice Apart from that I would also use STON class>>#toStringPretty: or #prettyPrint: true on a writer, if the target audience are humans. > On 20 Feb 2019, at 11:00, ducasse <stepharo(a)netcourrier.com> wrote: > > Hi > > I would like to use STON to save objects that non programmer will edit. > From that perspective I would like to be able to have a different class name > than the one in the implementation. > > For example > instead of > > 'SQOne{#question:''Where do developers typically write the Pharo syntax?'',#choices:[''a stamp'',''an envelop'',''a postcard''],#solution:3,#explanation:''It is common to say that the Pharo syntax fits on a postcard.â'} > > having > > âOneChoice{#question:''Where do developers typically write the Pharo syntax?'',#choices:[''a stamp'',''an envelop'',''a postcard''],#solution:3,#explanation:''It is common to say that the Pharo syntax fits on a postcard.â'} > > Iâm wondering if > - there are hooks for that in STON so that I can inject a map.

Looking for a STON in/out "factory"

by ducasse

Hi I would like to use STON to save objects that non programmer will edit. >From that perspective I would like to be able to have a different class name than the one in the implementation. For example instead of 'SQOne{#question:''Where do developers typically write the Pharo syntax?'',#choices:[''a stamp'',''an envelop'',''a postcard''],#solution:3,#explanation:''It is common to say that the Pharo syntax fits on a postcard.â'} having âOneChoice{#question:''Where do developers typically write the Pharo syntax?'',#choices:[''a stamp'',''an envelop'',''a postcard''],#solution:3,#explanation:''It is common to say that the Pharo syntax fits on a postcard.â'} Iâm wondering if - there are hooks for that in STON so that I can inject a map. I look super fast at the doc and browsing the code and I could not find them. - if someone build such kind of layers on top of STON Stef

Esteban, I'm glad that you are taking SETT for a spin. I am not familiar with the details of SETT, but if you could submit an issue[1] with the SETT project, then someone should be able to start looking into it:) I will ping them that you ran into issues ...

Pharo general questions for a commercial application

by BrunoBB

Hi, My name is Bruno i'been using Smalltalk since 1999 for commercial applications, mostly Dolphin, GemStone/S and Visual Works. Now we have a commercial project and we are going to use Pharo :) So we have some general questions. 1) Which version of Pharo to use in a production deployment 6.1 or 7.0 ? 2) We need a local database to Pharo app, which open source database is better to use with Pharo: mysql, postgree or .... In term of packages for Pharo. There is https://guillep.github.io/DBXTalk/ but i do not know if is up to date. 3) There is any documentation about deployment and maintenance for a Pharo + Seaside app ? I have found "2016-10-06-EnterprisePharo.pdf" but may there are other sources... regards, bruno -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
