[Pharo-users] Re: Silly question about storing and displaying currency amounts?

[David Pennington]

I come from a currency trader background and way back in 1983, I was dealing 
with this in North Star Basic and then UCSD Pascal  and into VisualSmalltalk 
(remember that?) so I have some history here. Trouble is, at 76, my little grey 
cells are letting me down bit. Excuses over. I will go back into the code and 
make sure that I scale all these ScaledDecimals to 2 and see if that helps.

BTW, I wasn’t suggesting that there was any problem with STON as that works 
brilliantly for me.

[Pharo-users] Silly question about storing and displaying currency amounts?

[David Pennington]

Hi everyone. I have a little bank analysis package for my own use but having 
trouble displaying and storing amounts. I parse out a CSV file from the bank 
and convert the amounts from text to ScaledDecimal. I then store these into a 
STON file, which converts them back to text. I then read them in and convert 
them back to ScaledDecimal again.

I am not used to ~Pharo have spent 24 years using VisualAge Smalltalk so I need 
a little bit of help because I am getting 1 Penny errors in the conversions. I 
can cope with this but I would like to get it right.

Can anyone give me a simple means of managing, say, an amount like £76.49 from 
the bank so that it stops coming back to me as £76.48?

Thanks for your response. I had the same problem on 8.0 and, in fact, had the 
same problem with VAST on Windows 10 and Windows 2012 server so I am not 
hopeful.  Running Linux is not an option for me although I could reconfigure my 
Windows 2012 Server as I have replaced that with an M1 MacMini.

For the time being, my client (or at least the club that I belong to, 
appreciate my efforts and are happy with as minimal HTML web site and a Blog 
but I got the MacMini hoping to solve this so I would like to see a solution.  
I am enjoying Pharo and don’t want. To have to leave it.

[Pharo-users] Re: Private Methods

[David Pennington]

I found this useful when creating commercial frameworks for VAST.  For 
instance, in the printing framework, I used the idea of a turtle (from 
turtlegraphics) to create pages. All the turtle commands - turn(50) etc - were 
public but the code that actually created the printing code was all private. 
Hence purchases knew not to touch the private methods.

[Pharo-users] Zeroconf downloading latest rather than stable

[David Pennington]

Hi there.

I have done a clean install of Pharo 9.0 using the zeroconf on get.pharo.org.

I am using curl https://get.pharo.org | bash 

When running the environment, I get a message at startup telling me that my VM 
is too old and that I should install a newer one - I am running it on an M1 
MacMini. 

However, after discussions on Discord, it seems that the above script installs 
the latest “stable”, not the latest VM. How do I get out of this little wrinkle?

it is still telling me that my VM is out of date. I have opened the VM window

[Pharo-users] Problem installing 9.0 on MacMini M1

[David Pennington]

Hi everyone. It is your favourite newbie speaking :-)

I have now got a new M1 MacMini which I want to configure up as a server for my 
Seaside apps.

So far, I have found that the Mac mini doesn’t have wget or brew installed! I 
have sorted wget but not brew.

Secondly, I have transferred all of my 9.0 stuff across but when I try and 
execute both paharo-ui or pharo (as terminal scripts) they both fail as they 
say that the “Paharo” is damaged and can’t be opened. You should move it to the 
bin.

I can open Pharo 9.0 directly but it tells me that the VM is too old for this 
image.

Can anyone help me please? (In words that I can understand:-)

Surely,  one of the bases of OO development is to subclass and extend existing

[Pharo-users] And it goes on - How do I fix a missing repository

[David Pennington]

I am obviously out of the loop when it comes to all of this repository stuff. 

So, I have imported my 8.0 code into 9.0 but I can’t add an extension method to 
ScaledDecimal because a repository is missing. I check what to do and get sent 
to Iceberg. Somehow, as a newbie, I am supposed to understand how iceberg works 
but, being a 76 year old VAST Smalltalker, I don’t. Surely, when I install 9.0, 
qashouldn’t I get everything I need for a basic image?

What do I do next. Attached is a screenshot of Iceberg.

[Pharo-users] STON reader problem

[David Pennington]

OK, so I have installed Pharo 9.0 with the M1 VM and everything is nice and 
quick. I am porting my code across and I have a problem that involves STON 
Reader.

I use this to convert my objects for storage in my text based database. I can’t 
run my code because STON Reader fails when reading in one of the objects.

The contents are as follows:

"{#entryName:'PAYPAL 
*COSYFEET',#entryDate:Date['2021-01-25Z'],#transactionID:'202101250001',#entryAmount:-5041216832887849/140737488355328s8,#entryCategory:nil,#entryDescription:'35314369001
 GB , 5959 22JAN21',#match:'N’}”

The errors is this:



Character 122 is at the conjunction of the 4 and 9 in the ewntryAmount: 
5041216832887849/140737488355328s8,

Any help on this would be great. I have a few thousand entries to fix if there 
is a problem with the file (although my code works fine with this file under 
8.0)

[Pharo-users] Re: New VM, how do I get it

[David Pennington]

Sorry yes, I gave you the screen shots without the code.

In V 9.0 if I execute the following

| working stream |
working := FileSystem disk workingDirectory

I get an Inspector on /Users/davidpennington. (Not a File~Reference)

In V 8.0 I get an Inspector on a FileReference 
(/Users/davidpennington/Documents/Pharo/images/Pharo 8.0 - 64bit (stable)).

As my database relies on disk paths, this is going to create a difference 
between the two versions which surely should not be so.

[Pharo-users] Re: New VM, how do I get it

[David Pennington]

I am sorry but, being a newbie to Pharo, a lot of what you say goes over my 
head.

How do I use Zero Conf?

I have loaded up the latest 9.0 from Pharo launcher. How do I get the <1 VM for 
that?

Sorry for being stupid.

[Pharo-users] New VM, how do I get it

[David Pennington]

Hi there. I am currently using v8.0 on a new M1 MacBookAir. When I save the 
image I keep getting a message telling me that my VM is too old and to download 
a new one. I have looked in my Pharo Launcher but there is no new one there. 
What do I do please?

[Pharo-users] Re: Seaside disappearing under Windows

[David Pennington]

I have looked at the code. There is only one method for reading and one for 
writing and they both close the file when they have done so that’s wouldn’t ’t 
seem to be the problem. It still doesn’t answer why it works on my M1 
MacBookAir and not on two Windows boxes :-(

I believe you are using some form of persistency that you built yourself, with data written in STON to files. Assuming you store each object in its own file, you are then also doing a lot of IO. Are you sure that you are properly closing your file streams, in all circumstances ?

It is possibly that you run out of IO resources.

Also, garbage collection on a server image (without a UI) is sometimes a bit strange, it can take a while to kick in.

I am just guessing here.

It is still not good that the image/vm quits without any notice, that is for sure.

[Pharo-users] Re: Seaside disappearing under Windows

[David Pennington]

I have finally given up on trying to sort this out. Under both Windows Server 
2012 and Windows 10 my Pharo image just exits leaving nothing, not even a crash 
file. Hence, I have fixed my MacBookAir so that it stays alive with the lid 
down and I am now using that as my Seaside server. It has been up for the last 
4 days so it seems that this is a Windows only problem and (hopefully) not my 
code.

In passing, I am a high-level programmer in Pharo in that I do not use any 
special calls or processes.

Nope. Just stderr. It is continuing to happy at random times so it is obviously 
connected to page requests. I have some logging in. Place so I have increased 
that to try and help get to the point where it happens.

Sorry to but in here but I have just moved my Pharo/Seaside server software 
from my MacBookAir, where it has run without issue for the last couple of 
weeks, onto firstly a Lenovo desktop running Windows 2012 server and then, in 
frustration , onto a Dell laptop but it hasn’t managed to run for 24 hours 
without crashing (by crashing, I mean Pharo just disappears!). I don’t us any 
OsProcess, just ordinary Seaside and Smalltalk code. It has happened three days

Both Windows machines have ample disk space (SSD) and 16GB memory.

How do I get a dump as I can’t see any files that would be regarded as so?

[Pharo-users] Re: Problem with Pharo 9 - repositories missing

[David Pennington]

That worked perfectly. I copied the three files across, created a new VM, 
copied my database and (apart from a single issue) everything worked fine.

Thank you so much for your help. It never occurred to me that this would be 
possible.

There is one big difference between Windows and the Mac but I will post that as 
a separate item.

Again, many thanks.

[Pharo-users] Recommended way to move a package

[David Pennington]

I have Pharo 8.0 on my MacBookAir and Pharo 9.0 on my server. I have having 
lost of trouble doing what I thought would be a simple process - File out a 
package on one and file it in on the other but I having lo=ts of trouble - to 
many issues to document to be honest.

So, tell me, how do I do this so that my package is in the new image along with 
the code extensions to other classes listed as being in the package. 

I can get the basic package in but the extensions never appear and I have too 
many to import individually.

Help!

[Pharo-users] Re: Problem installing Seaside on Windows

[David Pennington]

Thank you to everyone for your help. I sorted out the public and private
keys and shortened the path but it kept up with an authentication issue.
I deleted everything and installed V 9.0. I shortened its name and ran
the GitHub code and I now have Seaside installed and running. I now need
to install STON and I can get my code working.

What a great community this is!

According to my experiences this happens if Pharo images are located deeply in the directory path. It helps if you move the image in question to some higher level. In any case, C:\Pharo should work no matter what. 

Seaside has lots of dependencies which are then located under its repository.

Yes you hit the window filename length problem. 

Retry by creating one more pharo 8 image. Only don't take the default image name as you have taken. Change it to very short like p8-1 to keep image file name and consequently the folder name length to a minimum 

Then install seaside.  

If that doesn't work repost and we will try still another option

[Pharo-users] Re: Problem installing Seaside on Windows

[David Pennington]

OK, I got my software working fine on the Mac but I really need it on
Windows now so I have had another go. I have followed all the
instructions and I have a public key registered with GIT for both the
Mac and the Windows laptop. The Mac now quite happily installs stuff
that wouldn't load before. (TinyLogger). However, the Windows laptop now
get a lot further with the Seaside install but fails with this message:

"LGit_GIT_EEXISTS: Failed to stat file
'C:/Users/david/Documents/Pharo/images/Pharo 8.0 - 64bit
(sta...aximumAbsoluteAge.maximumRelativeAge.overflowAction..st': The
filename or extension is too long. 
" 
Any thoughts?

This is way to complicated for 70 year old developer.

This is indeed step one: make sure that you can check out code from git(hub) on the command line in Windows. Only if that works you can do the next steps.

BTW, once you have a repository checked out, you can just point Iceberg to it and load code.

PS: yes, you will also have to learn the basic of git(hub).

[Pharo-users] Code not showing all items in directory

[David Pennington]

Hi there. I am a long time user of VAST recently moved to Pharo. I have a 
directory that contains 20 JSON  items. I am using the following code to load 
all of them into a collection.

bucketList


| top fileDirectory bucketList nameList |
top := FileSystem disk workingDirectory.
fileDirectory := top / 'TinyKVDB' / self bucket.
bucketList := fileDirectory children.
nameList := SortedCollection new.
bucketList
do: [ :each | 
nameList add: each asString ] .
^ nameList

The code is only loading 18 of the items in the directory. I cannot see that 
there is anything different between there 18 and the other 2. Can anyone give 
me some clues here?

[Pharo-users] Sharing classes between packages

I have a small Key/Value database that I have written for my Seaside apps. I

[Pharo-users] Re: Problem when loading Pharo 9.0

[David Pennington]

I have been struggling all afternoon trying to install Pharo 9.0 on my M1 Mac. 
I have finally got everything loaded - 9.0 + Seaside, IniFile and STON. 
However, I am having some difficulty getting my software to run correctly. 

Firstly, when I try and import the STON objects from file I get an error which 
~I didn’t get with 8.0.  I am sure that I could sort this if I could do any 
debugging. However, when I switch to the debugger from Safari, I get the 
following error:


Instance of Process did not understand #debug:title:full:

Because of this the debugger doesn’t open so I can get no further. Can anyone 
assist please?

[Pharo-users] A question about packaging

[David Pennington]

Hi everyone. I have been using Pharo sine I got my M1 MacBookAir in late 
December. Before then, I was a VAST user since around 1995.

I have a question about packaging. Example, in VAST, I have an Application 
called Family_Accounts. Inside that I have some classes such as FAEntry, 
FABudget and so on. If I wanted to extend String to add an instance to convert 
to ScaledDecimal but using my special amount strings. I select the New menu 
item and then select either a class or an extension. As I want to extend 
String, I select Extension and then, within my Family_Accounts, I can see the 
String class so that I can extend it.

In Pharo, I can have a package called Family_Accounts. I can extend String, OK  
but my extension stays within the original package with, optionally, a 
Family_Accounts classification.  I can’t see how to add String to the 
Family_Accounts package to keep everything together in one place. Can this be 
done?

[Pharo-users] Re: Problem with Dictionary and Associations

[David Pennington]

Sorry, I meant to be factual not critical.

I am very pleased with Pharo and, now that I can see how it works, I am getting 
on really well with it.

I understand about resources as I have worked on my own for 20 years and have 
no-one to assist me. Never mind, Smalltalk is such a great language.

Please let me see the new VM and I will run some tests against it. I am 
impressed with performance as it is so  a native VM should be fantastic.

Firstly, I didn’t explain that all the visuals are written in Seaside and, 
currently, the pages are just there to deliver the output.

Secondly, as it is our bank account, I don’t really think that it would be 
appropriate. Let me mock up some stuff and see how I go.

[Pharo-users] Re: Problem with Dictionary and Associations

[David Pennington]

OK, here goes.

My finishing project formy Open University degree (started in 1974 and finished 
in 2017!) was a routing program for freight cars on US model railways - written 
in VAST Smalltalk with a Seaside front end and a Riak back end. Riak is a 
multi-user, fail over resilient Key/Value (K/V) database. I used it on a Linux 
server as I couldn’t get it going under MacOS. However, now I have finished my 
degree, I have disposed of the server so, for my new project I didn’t have a 
database. I had built my own K/V database some years ago to run the management 
and web software for a scale model shop that I owned at that time so I decided 
that I would recreate that database for my current use.

TinkKV is my Smalltalk K/V. It relies on the OS for saving and retrieving 
objects which are saved using STON (Smalltalk Object Notation) format. Simple, 
there are two levels of bucket - 1) ‘Bucket’ and 2) ’SubBucket’. There can be 
multiple buckets which can contain multiple sub buckets. In my application, 
items are stored under two keys - FAOEntry (the basic entry object) which is 
the primary bucket, and multiple sub buckets keyed by the category of each 
object. It is a single user, local machine DB which is extremely fast - 
retrieves 189 records in 0.18 seconds on an M1 Mac.

Family Accounts is a simple home accounts management package that will evolve 
over the coming month but basically imports transactions from a NatWest Sage 
Accounts format download and inserts them into the database. Each object can be 
categorised for budget control and each budget can be displayed. The program 
can import a set of regular items (in CSV format)  that recur monthly so that a 
monthly budget can be managed.  It is written in Pharo 8.0. 

I have been writing Smalltalk since 1990 when I started with Digitalk Visual 
Smalltalk but since about 1996 I have been using IBM/Instantiations VisualAge 
(VAST). I started the program, knowing nothing about Pharo, around the 15th 
January so it has taken just about a month of 1 -2 hours a day firstly to get 
to grips with Pharo and then to write the DB and Program. I have found Pharo 
quite difficult to come to grips with as, in comparison to VAST, it seems to be 
written for academics rather than business apps. However, once I got my head 
around how it was all put together, I found it an easy transition and great fun 
to use. I had expected to continue with VAST under Parallels but found that 
neither Parallels (well partially) or Windows 10 currently works successfully 
on an M1 MacBookAir. I did try to get hold of VisualWorks but didn’t get any 
response to my request for a download for some reason. I have written a good 
few frameworks for VAST so, now that my program is running successfully, I will 
have a look and see if I can port anything else. Watch this space.

Hi there Peter

I have been writing Smalltalk since 1990 first with Digitalk and then 
IBM/Instantiations VAST. However, I am a newbie with Pharo having only used it 
for the last 3 weeks so I am pleased to have got my first Seaside app working 
successfully - it’s a home banking management app that imports from Sage 
compatible CSV files supplied by NatWest. This is the only real difficulty so I 
am very pleased with the work.

I use my own brand key/value database that saves objects out to the disk. With 
my new M1 MacBookAir, I am getting read and write values around .3 second for 
125 records so I am very happy.

I have yet to look at deleting the old file before writing but I am sure that 
this will make it superb.

Many thanks for your help in this.

[Pharo-users] Re: Problem with Dictionary and Associations

[David Pennington]

Thank you for that but it doesn’t resolve my problem. Why does the stack move 
to an Association when doing the access to the dictionary? It is the 
Association indexing that fails as it won’t allow #entryAmount as a key.

If I inspect the following code (STON fromString: result ) in the line ^ self 
makeObject: (STON fromString: result ) I get an Association. Why don’t I get a 
Dictionary. I did two days ago when all of this was working perfectly and we 
were happily matching the Pharo Seaside display to our bank account :=)

Both of those were very helpful . Interestingly, I was expecting a file path

Great group. I will enjoy being here.

[Pharo-users] Is there a file selector in Pharo

[David Pennington]

I am moving to Pharo from VisualAge Smalltalk as I am now using an M1 MacBook.

I am building software to manage our home accounts and to do this, I download 
each day a text file from my bank that contains about 1 month’s worth of 
transactions.  In VAST, I use a FileSelector that opens a window and enables my 
to navigate to the Downloads folder and lets me select the current transaction 
file. This gives me the path to the file making it simple for me to open and 
parse it.

Is there a similar file selector window that I can use in Pharo? I can see how 
to open the Glamour browsers but not how to extract the path.

Can anyone help please?
