Iterating over a Dictionary

by 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! ---- peace, sergio photographer, journalist, visionary Public Key: https://pgp.key-server.io/pks/lookup?op=get&search=0x69B08F58923AB3A2 #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV @sergio_101@mastodon.social https://sergio101.com http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Re: Backing up data

by Stewart MacLean

Hi Sergio, I have used Fuel to good effect to store a tree of objects (with all interlinkages). Saving: saveTo: aFileOrName | aFileName | aFileName := aFileOrName fullName. FLSerializer serialize: self toFileNamed: aFileName Loading: loadFrom: aFileOrFileName | new | new := FLMaterializer materializeFromFileNamed: aFileOrFileName fullName. new ifNil: [^nil]. "becomeForward fails for nil!" self becomeForward: new Just make sure you don't have any references to objects outside of your model tree - you'll disappear down a black hole as it tries to save the whole image!

Re: Backing up data

by Yanni Chiu

Hi Sergio, I added a Movies demo, using a Soil database. There was a previous Accounting demo that had two versions (in memory database and Soil database) from which I based the new demo. I like the Movie demo because it is simple yet complex enough. I suspect the Accounting demo is too complicated to grasp as a first encounter. Iâm going to use the Movie demo for a presentation, so itâll continue to be tweaked. Mainly, Iâll be adding a way to use SoilTransaction with #commit, instead of #checkpointAndContinue. The code is at: [image: Seaside-Quasar.png] yannij/Seaside-Quasar: Pharo/Smalltalk code to use Quasar Framework in Seaside. Also, some demo apps using Magritte are provided. <https://github.com/yannij/Seaside-Quasar> github.com <https://github.com/yannij/Seaside-Quasar> Cheers, Yanni On Thu, Jan 18, 2024 at 11:11 AM sergio ruiz <sergio.rrd(a)gmail.com> wrote: > > [â¦] > > In the end, Iâll 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, itâs gonna be thinly veiled Smalltalk evangelism. >

Re: Backing up data

by Offray Vladimir Luna CÃ¡rdenas

Sergio, I would go with STON, as advised by Norbert (I don't have experience with Soil). One of the nice things of STON is that you can use whatever DVCS you like to versionate your data. For example, we locally use Fossil, while most people prefer Git. STON is super versatile! As an example, I used it with Grafoscopio, my Pharo powered interactive outliner/documenter, to store notebooks with Markdown stored inside STON, as you can see in [1]. And now I flipped that idea and I'm using STON to embed notebooks metadata inside Markdeep. In this way anyone can read notebooks directly in the web, without specialized software. [1a] is just the same document in [1] but with this flipped format idea (if you,re even more curious, look at the source code of the page at [1a] and youÂ will find that the STON representation of notebook cell/node medatada is pretty light and readable). [1] https://mutabit.com/repos.fossil/indieweb/file?name=indieweb.ston&ci=tip [1a] https://mutabit.com/repos.fossil/indieweb/doc/tip/indie-web--25zqu.md.html This is just an example of how STON allowed us to port lessonsÂ learned from Grafoscopio, made in 2016, to Lepiter, released in 2021, ensuring longevity of our community memory and data. Hopefully you will find STON pretty empowering in your own experiments.
