Re: [Pharo-users] Question about writeStream

by Guillermo Polito

In fact the question comes from the fact that they are not polymorphic and you should know if you're manipulating a closable stream or not... Maybe a solution is indeed to use #writeStreamDo:, that should behave well even for in-memory, collection streams, no?

Re: [Pharo-users] Pharo6 playground saving semantics and .changes?

One of the more hidden Playground features are named Pages. Double-click the page tab title and give it a name, it will then be saved automagically in pharo-local/play-stash (and auto saves on changes from then on).

Is it normal ? How do you mean that ? That FileStreams close automatically ? That is indeed the case, that they are closed as a finalization action (i.e. when they become garbage), but that I consider that a fail safe thing, not something you should rely on. They should be properly closed, like #readStreamDo: and #writeStreamDo: do. Streams over collections such as Strings do not need closing, as there is no opening either.

Pharo6 playground saving semantics and .changes?

Hi - I really like the playground metaphor, it really is such a nice way to experiment. However I've noticed that unlike older versions of Smalltalk, it seems that DoIt operations in playground don't end up in the .changes file anymore (which I guess is a mixed blessing when you want to recover). It seems that the new metaphor is that work you do is saved as a page and you can see versions of your page in the upper right menu?

Often I get duplicate looking pages in that menu and often I make a change and want to keep it but find it doesn't save and if I accidentally close my playground my changes in a page are lost? What are the semantics of page saving? An example - if you do a few gofer loads of utilities and the put a comment on the first line of the page (which gives it a nice title in the page dropdown), sometimes that comment will be saved other times not? I also think it might be nice to remove page versions to help tidy things up.

Pharo command line, stdout and integrating with other tools?

by Tim Mackinnon

Hi - I've been playing with using Pharo with Aws lambda and have got an image to launch in that environment. However now I need to better integrate Pharo with its calling environment - and I know there was a concerted effort to make Pharo play better which I should be able to leverage. So I am calling Pharo from a NodeJS wrapper (the suggested aws method for integrating alternative languages like Ruby, Go etc). I got this to work - however as an observation, it is rather awkward passing parameters to Pharo using the "eval" mechanism as other languages and environments frequently use the " character (particularly with Json) and this causes Pharo to fail if you don't \" this. I'm wondering if others have noted this and whether we can do this better somehow? For now a little nodeJS regex fu gets me past it. However my next question is about passing information back to the calling application. I can see that there is a stdout method on Fikestream that I can write to (great), however in my ./pharo eval call, which sends to a class method doing this - it also returns the result of that method or yourself? I guess this convention is great for the "eval 42 factorial" example but not so great of you just want to return some Json via stdout in a format of the calling environment? Is there something simple trick I can do to stop this extra result and just let me use stdout myself? Or do I have to return a Smalltalk string and then regex convert it to a new format in my calling language? I'm wondering if others have done this, or if anyone has some advice? It feels like a usecase that we might be able to do better somehow? Tim Sent from my iPhone

Custom Glamour browser for Dr. Geo scripting

by Hilaire

Hi, I try to build a dedicated browser for user scripting on DrGeo. I am learning from the Deep into Pharo Glamour chapter, extending the given example. Regarding the method category pane, I need both instance and class side, so I write it like this: categoriesIn: constructor constructor list title: 'Methods'; display: [ :scriptClass | scriptClass organization categories]. constructor list title: 'Script data'; display: [ :scriptClass | scriptClass class organization categories] The browser is defined as: buildBrowser browser := GLMTabulator new. browser column: #scripts; column: #categories; column: #methods. browser transmit to: #scripts; andShow: [ :a | self scriptsIn: a ]. browser transmit from: #scripts; to: #categories; andShow: [ :a | self categoriesIn: a ]. browser transmit from: #scripts; from: #categories; to: #methods; andShow: [:a | self methodsIn: a ]. browser transmit from: #scripts; from: #categories; to: #methods; andShow: [:a | self classMethodsIn: a ]. browser transmit from: #scripts; toOutsidePort: #selectedScript. browser transmit from: #methods; toOutsidePort: #selectedMethod. ^ browser but something is missing to get the listed method right depending on the category is instance or class side. I don't how to do it. Any tips? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Now that I've gotten a release of Caffeine out[1], and written some blog posts about it[2], I've turned my attention to Pharo in web browsers.

Norbert: Great answer. Spoken like a wise man. I want a web app to fill paper forms - like income tax forms say. The forms are scanned or input into the app. The developer provides the logic connecting the input and output fields of the forms. The users then use the app to fill their own forms, print them or send them electronically. Can Smalltalk provide a superior solution? How?

The error about saving the changes file comes from the fact that at startup, Pharo tries to open Pharo.changes in read and write mode, which is impossible if you are in a read-only environment. I am working on deploying Pharo in read-only, and it's one of the main problems that shows up during my tests. -- View this message in context: http://forum.world.st/Are-we-able-to-run-pharo-images-in-a-read-only-enviro… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
