Re: [Pharo-users] Pluralising messages or choosing word alternatives

[Tim Mackinnon]

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

Although I do kind of think that something on OrderedCollection like:

chooseBasedOn: count

^self at: ((count max: 1) min: self size)

Would be a nice general solution for other things (I’m kind of suprised there 
isn’t something like that there)

something like:


|./pharo Pharo.image "/run/the/script" |

to keep run cron jobs, etc.

I would like to start using Gemstone/s.

I got GsDevKit_home up and running, with no problems, but I am having 
a little bit of trouble figuring out how to proceed. I get what tODE

  * I got Seaside installed in the image, but I need several other
packages in my install: JSON, Soup, AWS S3, etc. How do I go about

I assume that you used the following tODE command to install Seaside, 
following these instructions[1]?


   |project install
   --url=http://gsdevkit.github.io/GsDevKit_home/Seaside32.ston|

The url in the command resolves to a project entry for Seaside32, that 
looks like this:


^ TDProjectSpecEntryDefinition new
baseline: 'Seaside3'
  repository: 'filetree://$GS_HOME/shared/repos/Seaside/repository'
  loads: #('Zinc Project' 'Welcome' 'Development' 'Examples');

'project clone --https --local Seaside3

--url=http://gsdevkit.github.io/GsDevKit_home/GsApplicationTools.ston';
gitCheckout: 'master';
status: #(#'inactive');
locked: true;
yourself

The `installScript` is run by the `project install` command and causes 
the two projects to be cloned into your shared git repository area. 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= --repo= 
[--loads=] \

  entry --config= [--version=] \
--repo= [--loads=] 
  entry --git= [--repo=] 
  entry --url= 

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

Re: [Pharo-users] Pluralising messages or choosing word alternatives

[Esteban Maringolo]

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'

Maybe you can use the conditional syntax of expandMacros.

[Pharo-users] Pluralising messages or choosing word alternatives

[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:

‘There is 1 occurrence of {1}’  vs ‘There are many occurrences of {1}’, which 
I’d like to write something like:

‘There ‘,  (‘is 1 ’, ‘are many ’) pick: result size, ‘occurrence’ 
asPluralBasedOn: result size, ‘ ‘,  result printString.

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

[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?

No problem Denis - I’m ready to dip a toe in on things like this. I just wanted

Hello, some classes, like Symbols or SmallIntegers, shares identity of value 
instances in the whole image (I may say it wrong), so:

1 == 1 copy. [true]
#aaa == #aaa copy. [true]

all other classes not, like Strings, Objects etc., so:

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

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.

What about MySQL connectors -- is anyone in the community using this, and
what are the most up to date packages?

Also I think we should add a DBs section to the Pharo Open Documentation
(based on this
email exchange).

Re: [Pharo-users] Pharo general questions for a commercial application

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).

Re: [Pharo-users] Pharo general questions for a commercial application

[BrunoBB]

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.

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

[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.

Re: [Pharo-users] Phorms repository?

[Manuel Leuenberger]

Found it.

RewriteTool (http://smalltalkhub.com/#!/~MarkRizun/RewriteTool/commits 
)
Phorms (http://smalltalkhub.com/#!/~CamilleTeruel/Patterns/commits 
)

Anybody has experience using these after Pharo 5, i.e. Pharo 6/7?

Re: [Pharo-users] RBPattern syntax

[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/brant/Refactory/Rewrite.html
 
.
 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 
) and Phorms 
(http://smalltalkhub.com/#!/~CamilleTeruel/Patterns/commits 
), which seems to 
have a more powerful pattern matching language.

Cheers,
Manuel

7.0.1 for sure.

There are multiple options. 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)

Here too, you have many options, depending on style/experience. Like you said:

There is 
https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessfulBuild/artifact/book-result/DeploymentWeb/DeployForProduction.html
 ?

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).

Please keep on asking questions, so that we can help you with your 
technology/stack POC.

Hi Steph,

In the class side of your class you need to override the method #stonName.

Re: [Pharo-users] Looking for a STON in/out "factory"

[Sven Van Caekenberghe]

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.

[Pharo-users] Looking for a STON in/out "factory"

[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.’'}

having 

‘OneChoice{#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.’'}

I’m 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
