Let me check it out.

It’s not too late. This is a fun “scratch my own itch” project. 

So there are no deadlines looming or anything..

I am in the same boat.

I have been using the pharo launcher for a few years, and it lets you do all of 
these things with no fuss..

[Pharo-users] Re: Iterating over a Dictionary

[sergio ruiz]

oh! this makes sense..

let me try this.

The trick is, i have used the AI system from JetBrains (in my day job IDE).. 
and it has figured out a bunch of smalltalk questions i had. Even questions 
about the pharo ecosystem.

It hasn’t always been 100%, but it got me to look in the right place quickly.

This was the first time it came up with something that looked right (i have 
seen this pattern everywhere).. but it was not correct.. 

Thanks!

[Pharo-users] Iterating over a Dictionary

[sergio ruiz]

I need to iterate over a dictionary.

I asked the AI buddy for a little help, and he says:

| myDictionary |

"Create a dictionary"
myDictionary := Dictionary new.
myDictionary at: 'one' put: 1.
myDictionary at: 'two' put: 2.
myDictionary at: 'three' put: 3.

"Iterate over the dictionary"
myDictionary do: [ :key :value |
Transcript show: key , ' -> ', value printString ; nl.
].

but when i try this, I get:

ArgumentsCountMismatch: This block accepts 2 arguments, but was called with 1 
argument.

Is the AI using a different dialect of smalltalk?

how would I go about acting on each pair?

Thanks!

[Pharo-users] Git Repositories browser vs. monticello

[sergio ruiz]

In the workspace, I see that Git Repositories browser if the first selection, 
and Monicello is marked as legacy.

The last time I was using Pharo, I think the Git browser was called “Iceberg.”

Are these the same thing?

Have we now made the move to Git as our primary SCM?

Thanks!

[Pharo-users] Re: Backing up data

[sergio ruiz]

The idea is, I have been a software engineer for the past three decades.

I REALLY love my profession (even though now, it’s pretty much sitting in 
meetings all day), but I love it.

I have a few projects I always wanted to do, because I just want to do them 
because they are useful to me.

I have architected and coded hundreds of giant projects. At this point, 
building anything with the big web frameworks just seems exhausting.

I have decided to bring each of these pet projects to fruition and then 
document how and why i made each decision.

Every project will be using smalltalk as the data store. If the project is a 
website, I will use seaside as the web framework. Otherwise, I’ll use the 
teapot as an API interface.

The series of articles I will write will be aimed at people in my position. 
People who are familiar with software development, and would like to read about 
it at a higher than tutorial level.

In the end, I’ll end up with:

- an application of some sort that scratches my own itch
- a pile of articles outlining how i designed the tool set for the application.

and in reality, it’s gonna be thinly veiled Smalltalk evangelism.

But i think it might be worthwhile to talk about this stuff in a pubilc 
platform.

[sergio ruiz]

Using this Will my links remain viable using this method?

Meaning that an event has a theater. That theater is also in the 
OrderedCollection of Theaters.

If the name of he theater changed in the Theaters collection, will that name 
change occur in the event theater object?

After bringing these collections back in via STON, will all of these 
relationships remain intact?

OOH..  I like this idea.

I’ll do a quick test on this and see if it works as expected..

For now, I want to store the data in the image.

The trick is, I like to start with a fresh image every few days. So, I’d like 
to open a new Pharo, pull the source code, then pull the data.

Thanks!

[Pharo-users] Backing up data

[sergio ruiz]

I have been in the relational database world for decades. One of the things 
that is super simple is backing up and restoring data.

Sometimes, it makes it makes sense to pull the production data into 
development. In the case of a catastrophe, it’s super simple to restore data 
from a backup.

I am thinking of backup strategies for my data once again, and am wondering if 
things have changed since I was last using smalltalk.

I am thinking of the following:

STON
I could dump all of my data into STON, but there is one slight twist. In this 
project, it’s just making a list of movie listings. There are three basic 
classes: Theater, Movie, Event. Each of these classes stores an 
OrderedCollection of items of that type on a class variable, as I’ll need to 
access each on their own.. so, if an event has a theater, I’ll need to access 
Theaters on their own, and Movies on their own.

So, I would have to rebuild the list of Theaters from the Theaters in each 
event. Otherwise, I would lose the link between the Theaters on the Theater 
class variable and the Theater in the Event instance.

Am I thinking about this incorrectly?

Gemstones
I am totally into the idea of using gemstones. Is there a backup and restore 
for objects here? do the relationships remain?

Voyage
This seems like a good solution, but I would rather stay in the smalltalk 
object store.

Ideas?

Thanks!

[Pharo-users] Troubleshooting ByteArray

[sergio ruiz]

Hi, all.

I am working on creating a PDF with Artefact 
(https://github.com/pharo-contributions/Artefact) and am having an issue 
running the first example.

the Example looks like:

PDFDocument new add: (PDFPage new add: (PDFTextElement new text: 'Hello'; from: 
10mm@10mm)); exportTo: 'test.pdf' asFileReference writeStream.


When running this, I get the error:

Instance of ByteArray did not understand #isByteString

indeed, ByteArray does not have a method called isByteString.

I have tried creating a method that returns either true or false (I tried them 
both), but I have not successfully built the PDF.

The method calling isByteString looks like:


ZnUTF8Encoder

next: count putAll: string startingAt: offset toStream: stream
"Write count characters from string starting at offset to stream."
"Overwritten for performance reasons - create a fast path for byte 
strings"

string isByteString
ifTrue: [ self next: count putAllByteString: string startingAt: 
offset toStream: stream ]
ifFalse: [ super next: count putAll: string startingAt: offset 
toStream: stream ]

I TOTALLY get this. This is a whole bunch of very specific questions. But my 
ultimate goal is to take a deep dive into stream processing to figure this out.

Thanks!

Is there an accepted way to do this (encryption)?

[Pharo-users] Document layout with Pharo

[Sergio Ruiz]

Hi, all. 

I am looking to create a newspaper like listing of movie showtimes.  Initially, 
I thought of using imagemagick’s annotate command to generate the output. 

Thinking further, I thought it might be worthwhile to generate a LaTeX file, 
and render that to a jpg. 

Then, I thought there might be a better way to do this natively in smalltalk.

Does anyone have any idea how I might generate a document that can be converted 
to an image with a reasonable amount of control of the layout?

Thanks!

[Pharo-users] Removing and object from an OrderedCollection in the inspector

I am trying to remove some objects from an OrderedCollection in the inspector.

I have class called Event. This has a class variable called Events which is a

So, i inspected “Event Events” and I see my ordered collection.

In the inspector, I select on of the objects, and I try to evaluate “Event 
Events remove: self”.. But I am getting an error: an Event not found in 
OrderedCollection.

Does anyone have any ideas on how i’d do this?

[Pharo-users] Updating objects in the inspector

[sergio ruiz]

Hi, all.

I have been away from Pharo/Smalltalk for several years, but I am coming back 
to it now. I am a senior developer, but haven’t used smalltalk in any 
professional projects.

I also found that I don’t do ANY pet projects for fun anymore, as the current 
batch of languages/frameworks are not fun. They are effective and all. But not 
fun.

I am starting a bunch of “scratch my own itch” projects. I’ll be using Pharo as 
the data store, and maybe more. The thing I really want to do is document the 
usage of Pharo in my projects, and explain the toolchain, and why i chose each 
piece.

My first project is to take a list of movie events from the local theater and 
create a listing reminiscent of the newspaper listings we read in the olden 
days. 

I have my models set up and figured out, but I have a really simple question.

How do i change the value of an instance variable in the inspector. It looks 
like it should be super simple, but it’s not working.

In this case, I am just trying to take the period out of a string. See that 
attached image.

Thanks, all!

[Pharo-users] [Pharo Mooc] Change colors of test results

[sergio ruiz]

Hey, all.. 

I am taking the Pharo Mooc, and was wondering:

is there any way to change the color next to the test method name?

I am colorblind, and I can’t tell the different between green and yellow.

Thanks!

[Pharo-users] Extracting MP3 metadata

[sergio ruiz]

One of the projects I am working on requires the reading of mp3 metadata. I see 
this is covered all over the place in different languages, but I don’t see one 
for Pharo/Smalltalk. Does anyone know off hand of something like this?

Would it be worthwhile to do something like this in Smalltalk, or would it be a 
better idea to find and executable somewhere, run it, and parse the data there?

Thanks!

[Pharo-users] Deploy a Pharo 8 application remotely

[sergio ruiz]

Hey, all..

I put together a quick REST interface to use internally here.

It’s ready to launch to a production server, and I’m not sure how to set it up 
on the remote server.

The current zeroconf downloads and sets up a Pharo 7 instance.

What I would like to do is set up Pharo 8 on the remote server, and just 
replace the image and changes with mine, and start up the Teapot server  
remotely.

I usually just use rsync to update the remote image and changes files, but I am 
not sure how to go about getting the correct setup to run the correct (Pharo 8) 
interpreter remotely.

I tried doing:

curl https://get.pharo.org/64/80 | bash

But this brings down only the changes and image files down.. no pharo-vm.

will the pharo-vm that runs pharo 7 also run pharo 8?

Thanks!

Just checking in on this.

I started up a REST API project in Pharo 8. I thought I read somewhere that 
Teapot was failing tests in Pharo 8.

I fired it up, and put together the beginnings of the project, and it looks 
fine. All tests pass.

There was one SSL test that was not running in 7 either, but I’ll take a look 
at that when I get a chance.

Thanks!

[Pharo-users] OrderedCollection as an instance variable

[sergio ruiz]

I'm implementing an instance variable as an OrderedCollection, and am doing 
something idiotic.

I have an Artist class.

An Artist can have many tracks:

tracks
^ tracks ifNil: [ self tracks: OrderedCollection new ]

tracks: anObject
tracks := anObject

Doing something like:

a := Artist new.
t := Track new.
a tracks add: t

Gives me the error:

Artist(Object)>>doesNotUnderstand: #add:

Once I get past that error, which will evaluate `a tracks`, I can run this.

I get why it works the second time, but I don't get why it thinks the instance 
of Artist is the receiver of add: on the first run.

Thanks!

[Pharo-users] [OrderedCollection] add a reference or a copy?

[sergio ruiz]

I think my understanding of OrderedCollections has been incorrect for a very 
long time. I have never had a situation where it mattered, but in modeling a 
current project, I think I have been approaching it incorrectly.

Since I have been using Smalltalk, I assumed that a copy of an object is added 
to an OrderedCollection. A quick test shows that a reference to that object is 
added to the OrderedCollection.

I just wanted a sanity check on this. Is this true with all collections?

Thanks!

when you say references, how does this look in pharo? I don’t know that I have 
used such a relationship.

I was thinking that an object would have an instance variable that was an 
ordered collection of objects.. So having one object belong to two parent 
objects could be tricky.

[Pharo-users] Modeling HABTM

[sergio ruiz]

I am currently putting together a Seaside website for my radio show. I am 
trying to figure out how to model the "has and belongs to many" relationships.

Each episode can have many tracks, each of these tracks can belong to several 
episodes.
I want to be able to present a listing of which episodes each track appears in, 
and a listing of tracks for each episode.

The approach I have seen on this is to create an intermediary object and store 
a set of ids on this, but this seems a little clunky, and it seems like there 
would be a clean way to do this.
Am I missing something?
Thanks!

[Pharo-users] [gemstones] Use case for GsDevKit_home

[sergio ruiz]

I have another project coming up, and I have free reign over the tech
stack. I am gonna use Pharo, but I'd like to spend my up front time on this
project figuring out the things I usually wait until the end to do. One of
these issues is setting up gemstones.

I would like to use GsDevKit_home, but I want to make sure that the use
case I am envisioning is in keeping what this package is set up to do.

My vision is something like:
- Deploy a stone to remote production server.
- Develop in the latest version of Pharo on my local machine, keeping my
project in git.
- When it's time to deploy,  use tODE client to tell the production server
to grab the latest code, and we're done.

Does this sound reasonable?

Also, one thing that I find invaluable in troubleshooting applications
written using relational databases is to be able to be able to just dump
the production database and load it up on my local machine. Is this
possible using gemstones?

Thanks!

Re: [Pharo-users] Repeateble URLs - REST?

[sergio ruiz]

I like that http://www.bagelconcertfinder.com uses Seaside and also my
Twitter Bootstrap Library.


Thanks so much for your library!

I have built several applications in seaside, and always dig using it..
it’s my go to framework when I do a project on my own..


Seaside by default works with stateful (web) components - making it easy to
develop - but possibly hard to scale to be the next Twitter, Amazon, ... ;)

most everything I work on will never be the next twitter or amazon.. so i
am fine tweaking here or there..

I have thought about doing exactly what you are talking about..

In my day job, we use LOTS of Angular. I thought about setting up a REST
interface using Teapot, and using angular for the web part..

This provides for a much more interactive user experience, but I also
totally love how seaside works..

Maybe for my CMS type project, I’ll use Teapot/Angular..

I will have to think about this for a bit…

I did a project last year where I used teapot in conjunction with an SMS
interface to create a very useful bot..

This was incredibly handy..

[Pharo-users] [Seaside] Resource Based routing

[sergio ruiz]

Okay, gathering info regarding my last post.

I need to create REST urls to point to things in my app like blog posts,
show notes, etc..

I am thinking to do this, I should probably follow this:

http://book.seaside.st/book/advanced/restful/handler-filter

Am I on the right track?

Thanks!

Given the conflicting advices on REST, you can try and adhere to one-two
sources of advice.

[Pharo-users] Repeateble URLs - REST?

[sergio ruiz]

Hi, all..

I am looking to have a repeatable url so users can save them and share
them.. something like:

www.bagelconcertfinder.com/zipcode/44805

and in my next project, I’ll be doing something like a CMS where you would
get:

/blog_entries/this-is-the-path

I am thinking of using REST to flesh out the paths..

does this seem reasonable?

[Pharo-users] Running pharo in daemon mode

Hey, all..

I found my issue.. I need to be running in daemon mode.. i was running with
&, but as soon as my connection lets go, the app dies..

I tried using daemon tools, but it looks like the site stays up for one
second, and a new PID is generated..

Anyone have any hints on how people are doing this lately?

Thanks!

[Pharo-users] Pharo Image with Seaside dies without any clues

[sergio ruiz]

Hi, all.

My seaside image seems to run for an indeterminate amount of time here and
there, then just stops running without writing to PharoDebug. How do I  go
about debugging the application crash? Is there another log somewhere?

It looks like there are other (path) issues when the the image starts up,
though..

the initial error log looks like:

https://gist.github.com/sergio101/8ac04fe5db4786c36fa3bf795807da9a

I’m not sure these errors are related to the image just randomly crashing
here and there.

[Pharo-users] Trying to understand Developing with Pharo, Deploying with Gemstone/s

[sergio ruiz]

I have an app that is ready to deploy to alpha. I usually do this by
creating a script that builds a minimal pharo image, and run that on a
cloud server.

I then use TelePharo to make any live tweaks that need to happen, and
something like:

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

to keep run cron jobs, etc.

I would like to start using Gemstone/s.

I got GsDevKithome up and running, with no problems, but I am having a
little bit of trouble figuring out how to proceed. I get what tODE is
doing, but I don’t get how to do the things I normally do:

   - 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
   installing those?
   - How do I install my main package? It’s in an Iceberg project.
   - How do I update my Iceberg project while it’s live?

I think those questions will get me into beta pretty quickly.

Thanks!

printFormat: #(3 2 1 $/ 1 1 2)

which goes like:

printFormat: formatArray
"Answer a String describing the receiver using the argument formatArray."

^ String
new: 16
streamContents: [ :aStream | self printOn: aStream format: formatArray ]

But i am unclear on how to assemble this formatArray to get a date like:

mm/dd/

any ideas?

Thanks!

[Pharo-users] Pharo Launcher and Command Line

[sergio ruiz]

Hey, all.

I REALLY dig the pharo launcher! this is a great addition.

One quick question.

How do i go about running a method from the command line?

Specifically, I usually run something like:

./pharo Pharo.image ../scripts/setup-client-application.st

To set up a new image with the current project.

I am not sure which executable to run with this that will execute the same
executable as pharo launcher.

Thanks!

Re: [Pharo-users] Pharo 7 image does not load

[sergio ruiz]

WOW!

Thanks so much for the in depth!

This prompted me to do the same thing with a new image..

If it turns out that this takes more than half an hour, i might just create
a new image and load my project up..

Thanks again!

[Pharo-users] Pharo 7 image does not load

[sergio ruiz]

I have been working in my image all day today, and it was working great.

This evening, when I went to fire it up, it appears to start, but I am not
seeing the image running. The icon hangs, and it does nothing.

Here is an my debug.log for just one iteration of this.

Any help would be appreciated!

You can also double click into the repository, or click on the "Packages"
menu.


For some reason, I am not  getting “Packages” in my menu:

[Pharo-users] [Iceberg] Loading my git project into a new image

[sergio ruiz]

I had a troublesome image today, so my first thought is to dump the image,
and load the packages back up in a new image.

While I can clone the the repo on in my new image using Iceberg, I can’t
figure out now to load the packages, now that they are loaded up via
iceberg.

under “loaded version” i see “no package loaded”. under “status” i see “not
loaded”..

Thanks!

[Pharo-users] My Pharo image is crashing

[sergio ruiz]

I have an image that I have been working on for a few weeks.

Today, when I went to edit a method, the image crashed, and it crashes
whenever I try to save.

normally, I wouldn’t care, but this one has a bunch of data (as Ordered
Collections in class variables).

The current size of the image is 198.6M. How big can they usually get
without problems? I saw the number 7G somewhere, so it seems fine.

Here is my error log: https://pastebin.com/2yWGCbAC

Any ides?

Thanks!

[Pharo-users] Working with an entire project in git

[sergio ruiz]

Hey, all..

I was just checking in to see the progress of managing an entire project
with git.

The last I checked in, this was a work in progress.

My current pet project consists of a handful of classes with maybe two
handfuls of required packages.

Is the entire metacello configuration being handled on github yet?

I would like to work this into my workflow so that I can do something like:

- Grab a fresh Pharo
- Pharo.image ../scripts/setup-client-application.st where the setup script
just grabs the Configuration and loads and starts a fresh project.

Thanks!

Re: [Pharo-users] Lazy vs eager initialization

This makes sense.. in the the cases i am writing now, all objects will, by

Thanks!

[sergio ruiz]

If a model has a list of things.. such as a user that can/may have lots of 
pets, are there any real benefits to initializing the list of pets lazily?

like:

self pets := OrderedCollection new.

vs.

pets
 pets ifNil: [self pets: OrderedCollection new]
 ^ pets

Currently, i pull the image and run it local, but an email with a stack trace

Hi, esteban..

In this case, the persisted object is TestBox..

it does show up just fine in Mongo, but the OrderedCollection of points does 
not.

For some reason, I am not able to do this:

Object subclass: #TestBox
instanceVariableNames: 'origin corner pointList'
classVariableNames: ''
poolDictionaries: ''
category: 'PrintBot-Models’!

initialize
pointList := OrderedCollection new.


If i do something like below, I don’t see the list of points ever show up in 
mongo..

Ideas?

b := TestBox new.
b save.
p1 := Point x:0 y:0.
p1 save.
p2 := Point x:12 y:343.
p2 save.

b origin: p1.
b corner: p2.

b save.

b pointList add: p1.
b save.
b pointList add: p2.
b save.

Re: [Pharo-users] GemStone/S on Docker?

What do you mean by „something that doesn’t require refactoring“ ?


I used mongo voyager for a few projects.. i ended up having to refactor here 
and there to get it to work (to connect my data mongodb).. I’d like to try an 
object database.


I think to put GemStone/S on docker should be easy package wise. Years ago when 
I used GemStone I created these scripts
