Some great suggestions here guys - I had forgotten there were conditionals in expandMacrosâ¦ that is the better solution.

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?

Of course I would recommend that you maintain a "production sandbox" stone that is basically a periodic copy from production that you use to test your code prior to deploying into production ... there are some additional details about GemStone that you should be aware of (mainly in the area of dealing with class shape changes and persistent garbage collection), but this should get the ball rolling ...

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. 'There <1?is:are> <2p> <1?occurrence:ocurrences> of <3p>' expandMacrosWith: occurences = 1 with: 3 with: 'Foo' Esteban A.

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. Anyway I was curious if there is something to help with messages like: âThere is 1 occurrence of {1}â vs âThere are many occurrences of {1}â, which Iâd like to write something like: âThere â, (âis 1 â, âare many â) pick: result size, âoccurrenceâ asPluralBasedOn: result size, â â, result printString.

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?
