The project entries for both projects are also dropped to a common disk location and will show up in your `project list` as unloaded projects in all of the stones you create, so the `install` only needs to be done once. I'm pointing this out because you can use the `project entry` command to create project entries in the "common disk location" by using the `project entry` command ... here's the man page obtained by doing `man project entry` (`man project` will list all of available `project` commands): NAME project entry - Create a new project entry SYNOPSIS project entry --baseline=<project-name> --repo=<project-repo> [--loads=<load-expression>] \ <project-path> entry --config=<project-name> [--version=<project-version>] \ --repo=<project-repo> [--loads=<load-expression>] <project-path> entry --git=<project-name> [--repo=<git-repo-path>] <project-path> entry --url=<url-for-project-entry.ston> <project-path> DESCRIPTION The project entry specifies project options used by the `project list` window. A project entry can be created for loaded projects or for projects that have yet to be loaded. There are three basic types of project entry: Git, Metacello, and HTTP. Git Project Entries ------------------- For Git project entries you define the name of the project and the location on disk where the git repository is located. For example: project entry --git=projectHome --repo=$GS_HOME /sys/local/server/projects Metacello Project Entries ------------------------- For Metacello project entries you define the name of the project, the type of the project (baseline or configuration), the repository where the baseline or configuration may be found, and (optionally) the package/project/groups to be loaded. For configurations, you also specify the version of the project to be loaded. For example: project entry --config=External \ --version=1.0.0 \ --repo=http://ss3.gemstone.com/ss/external \ --loads=`#('Core')` \ /sys/local/server/projects project entry --baseline=External \ --repo=github://dalehenrich/external:master/repository \ /sys/local/server/projects If you don't specify a `--loads` option, the 'default' group is loaded. Once you have created a project entry, you may change or add attributes. For example, you may want to change the status to #inactive. HTTP Project Entries -------------------- For HTTP project entries, you an download an existing project entry from a web-site. For example: project entry --url=http://gsdevkit.github.io/GsDevKit_home/Seaside31.ston \ /sys/stone/projects Downloads a project entry from http://gsdevkit.github.io/GsDevKit_home/Seaside31.ston into the /sys/stone/projects node. Once a project is loaded, only changes to the loads specification, locked attribute and active attribute may have an effect. The remaining information is taken directly from the loaded project itself. Any changes you make will take effect after the project list is refreshed. If there is already a project with the same project name in your project list, the download will be skipped. If this command is run as a result of a project entry install script, the project path of the outermost project entry (i.e., the project that initiated the original install script) is used instead of the <project-path>. Project Entry Attributes status When a project entry is initially created, the status is set to #active. Active projects are listed in bold and sorted near the top of the project list. gitRootPath For projects use github repositories, the gitRootPath specifies a location on disk where the git repository should be located. This attribute is used by the `project clone` command. If a project entry does not have the gitRootPath explicitly set, then the path returned by TDProjectEntryDefinition class>>defaultGitRootPath is used. The value of TDProjectEntryDefinition class>>defaultGitRootPath can be set on a session by session basis. locked For Metacello projects, you may specify that the project entry is locked. By locking a project entry you can ensure that the specified project version (if applicable) and repository will be used whenever the project is loaded by reference from another project. EXAMPLES project entry --config=External --version=1.0.0 --repo=http://ss3.gemstone.com/ss/external \ --loads=`#('Core')` /sys/local/server/projects project entry --baseline=External --repo=github://dalehenrich/external:master/repository \ --loads=`#('Core')` /sys/stone/projects project entry --git=projectHome --repo=$GS_HOME /sys/stone/projects project entry --url=http://gsdevkit.github.io/GsDevKit_home/Seaside31.ston \ /sys/stone/projects NOTE - use the `tode it` menu item to run the examples directly from this window. SEE ALSO browse class --exact --hier TDProjectEntryDefinition "The Metacello Lock Command Reference" [1] [1] https://github.com/dalehenrich/metacello-work/blob/master/docs/LockCommandR… browse method --spec `TDMetacelloTool>>projectentry` NOTE - use the `tode it` menu item to run the commands directly from this window. Soooo, you should create a project entry for each of your projects. I'm not sure which of the JSON projects[2] you are using, but if you are using NeoJSON[3], then you are in luck because there is an existing port of NeoJSON[4] to GemStone. The project is not updated to the latest NeoJson release, but that can be done. I don't have a lot of free time these days, but I would certainly be willing to answer questions and resolve specific issues,,, Anyway, using NeoJSON as an example here's the project entry command: project entry \ --baseline=NeoJSON \ --repo=github://GsDevKit/NeoJSON:gs_master/repository \ --loads=`#( 'Core' )` \ /sys/local/server/projects II you look at the file $GS_HOME/sys/local/server/projects/NeoJSON.ston: ^ TDProjectSpecEntryDefinition new baseline: 'NeoJSON' repository: 'github://GsDevKit/NeoJSON:gs_master/repository' loads: #('Core'); status: #(#'active'); locked: false; yourself Then a `project clone NeoJSON` will clone the project to $GS_HOME/shared/repos/NeoJSON. Then a `project lock NeoJSON` will lock the project, producing this in $GS_HOME/sys/local/server/projects/NeoJSON.ston (note the `locked` field is now true): ^ TDProjectSpecEntryDefinition new baseline: 'NeoJSON' repository: 'filetree://$GS_HOME/shared/repos/NeoJSON/repository' loads: #('Core'); status: #(#'active'); locked: true; yourself At this point any reference to the NeoJSON project in Metacello spec will use your locally cloned git repository for every stone that you create. There are a few differences between the project entry produced by the command:and those that are present up on github[5] and downloaded using the command: project entry --url=http://gsdevkit.github.io/GsDevKit_home/NeoJSON.ston /sys/local/server/projects Here is the downloaded project entry: ^ TDProjectSpecEntryDefinition new comment: ''; projectUrl: 'https://github.com/GsDevKit/NeoJSON'; baseline: 'NeoJSON' repository: 'github://GsDevKit/NeoJSON:gs_master/repository' loads: #('Core'); installScript: 'project clone --https --local NeoJSON'; gitCheckout: 'gs_master'; status: #(#'inactive'); locked: false; yourself ... I haven't gotten around to adding the extra fields to the `project entry` command, but it is pretty easy to copy the .ston files and edit the fields to your liking... So for each of the projects that are part of your application you would: 1. create a project entry 2. clone the project 3. port to gemstone (if needed) [1] https://github.com/GsDevKit/GsDevKit_home/blob/master/docs/gettingStartedWi… [2] https://github.com/search?l=&p=1&q=JSON+language%3ASmalltalk&ref=advsearch&… [3] https://github.com/svenvc/NeoJSON [4] https://github.com/GsDevKit/NeoJSON#gemstone-installation [5] https://github.com/GsDevKit/GsDevKit_home/blob/gh-pages/NeoJSON.ston > > * How do I install my main package?

Why not use the condition macro so you have a single string literal, that in the future could be used for translation? E.g. | occurences | occurences := 3.

Pluralising messages or choosing word alternatives

by Tim Mackinnon

I was browsing some of the Pharo issues (always worth doing) - and noticed an interesting one about Test results reporting and pluralisation (https://github.com/pharo-project/pharo/issues/2578) In it, I hadn't noticed String>>asPluralBasedOn: before (and judging from many messages in the image, many others hadn't either). I'm fixing something similar for a refactoring bug and can use this technique there (although from memory, it comes with a health warning as if ever we want to internalise the messages in Pharo, this will need a different approach). However we are probably a distance from doing that - so cleaning up what we have is a good start.

Re: [Pharo-users] how to test, if the class has "shared identity" of instances in the whole image (SmallIntegers, Symbols...)

by Richard O'Keefe

It is not clear to me what the semantics of such a selector would be. Consider this example: t := [:x | x copy == x]. a := t value: 1.0e38. b := t value: 1.0e308. What do you expect a and b to be? GNU Smalltalk: a=true, b=true. My Smalltalk, 32-bit or 64-bit: a=true, b=true. Squeak/Pharo, 32-bit: a=false, b=false. Squeak/Pharo, 64-bit: a=true, b=false. Squeak/Pharo, after a patch: a=true, b=true. There are two quite different reasons why x copy == x might be true: * x is immutable (including its parts), and can be thought of as a mathematical value, so that there is no need to copy it Examples: every kind of number, characters, booleans, immutable collections, block closures * x is a way of accessing a unique resource, and should not be copied, so making copy the identity is a safety measure. Examples: Semaphores, Mutexes, SharedQueues, data base connections, some kinds of streams, singletons. * Laziness or error (inherited method not revised). What is your use case?

Tim Mackinnon wrote > Yeah - I have a similar issue with ExternalWebBrowser... that drags in... > [a] huge raft of tests My workflow is to make every project one monolithic package until the need to do otherwise is presented (like right now!). I used to carefully think about theoretical use case scenarios and split projects up along those lines, but management (especially with the tooling available at that time) seemed to explode exponentially, so I went monolithic. After several years of experience, this is the first time someone expressed a pain point (that I remember anyway)! This seems to validate the current approach and my suspicion that preemptively creating multiple packages is akin to premature optimization. Tim Mackinnon wrote > I think what we have to do is submit pull requests to these projects such > that they create better baselines with Groups Yes! I will happily integrate. The tests may need to be promoted to a package if they are currently in a tag, but 'Core' without and 'Tests' with seems appropriate given your issue. I don't have a strong opinion on the default but my guess is to leave it as is (i.e. all packages) because newbies will get the tests (i.e. documentation) and advanced users will know enough to customize. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi Bruno, Is good to see you here as well :) 1) 7.0+. If you're in Windows only 32 bit is supported. 2) For RDBMS forget about DBXTalk and Garage, I would suggest you go straight to the PostgreSQL client (P3) or SQLite. Those are maintained and used, the rest... who knows. If you need ORM you can use Glorp with any of those. 3) As Sven mentioned there are many options, there is people using Docker containers managed by Docker Swarm, so the options are many. But if you use Seaside with stateful sessions (you'll need affinity by session or IP). Regards, Esteban A.

Sven, Thanks for you answer and links. SQL will be enough and no need for a complex ORM. I will take a look at: https://github.com/svenvc/pharo-server-tools Thanks again ! regards, bruno PS: my client has an running Java app and need another app to do some functionality and they will give Smalltalk (Pharo) and opportunity. The apps will be connected through a database and web services. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

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).
