Hi Tobias,

...

What is the squeak equivalent of VA Smalltalk's ObjectLoader and ObjectDumper?

What do they do?

ObjectDumper serializes objects and ObjectLoader deserializes the resultant string. They work with in memory stream or disk files. I think things like Fuel, Ma Serializer and SIXX would be based on classes like ObjectLoader and ObjectDumper. But I'm not sure.

I only need a very lite version so I don't think I need those full packages (again I'm not sure).

While DataStream/SmartRefStream are the traditional Squeak way of serializing objects, I'd go with Fuel.

There is no "abstract" object serializer in Squeak.

binary object serializer

An object serializer takes an object graph as input and answers a binary array.

http://wiki.squeak.org/squeak/6451

What is good with the Ma Serializer

http://wiki.squeak.org/squeak/6452

that it works with different Squeak versions. Fuel is tied to particular Squeak versions. That means the Fuel object you get from Squeak 4.6. is not guaranteed to load in 5.1. For Ma Serializer this is the case.

You could do wonderful tricks X saveOnFileNamed: fileName export X as fileName.obj Drag and drop this in any .image which have this .cs and and Inspector rise letting you play with it. Example. I have a Squeak derived thing running www.squeakros.org http://www.squeakros.org/ on a Power Mac G4of 1989 uer: visita pass: (let this in blank)

inside i convert all swiki page to .obj DivagacionesIndex is the class which lets me find , delete, rename the “pages” Today DivagacionesIndex have 5786 pages as I use the system also

export "DivagacionesIndex export" self compact. self default saveOnFileNamed: 'DivagacionesIndex' , DateAndTime now asUnixTime asString

import: aDictionary "DivagacionesIndex import: self" Default := aDictionary I have a running in the alpha based in a fork of Cuis 3.2 reduced and is easy export from Squeak to Cuis if i need. Also for the users of system DivagacionesUsers getDataBase explore gives 202 OrderedCollections with user name, email, password

As you see is a real use case. Maybe Herbert have a complex use of JSON , which I also have nice examples to share with all

Feel free to send direct mail if you wish or I could chat on Skype,IRC,Facebook,Slack Cheers Edgar @morplenauta

Yes, Ma Serializer is easy to load through the SqueakMap catalog.

File out example:

MaObjectSerializer new fileOut: MyBigDataDictionaryObject toFileNamed: ('../../2017-01-18_DDic10.ma') in: FileDirectory default

File in example:

MyBigDataDictionaryObject := MaObjectSerializer fileIn: ('../../2017-01-18_DDic10.ma').

Chris Muller wrote that he used Ma Serializer get the SSRepository object (the root object of http://source.squeak.org) out of the 3.11 image it was running in 2016 into a 5.1 image.

Hi Guys,

Thanks for the help. I went with Ma Serializer. It looks like way more than I need but it was easy to load and it works.

Hi Tobias

(PS: hi Lou, this is what my server tells me when it rejects to send mail to you:

The server “mail.gmx.net” rejected the address “Lou@Keystone-Software.com”.

The server response was: Requested action not taken: mailbox unavailable invalid DNS MX or A/AAAA resource record )

That's odd! I just tried a test and sent myself an email and it worked just fine. So, I don't get what the problem is.

Anyway, posting through the news group seems to work okay.
