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

Logging in with VNC

by sergio ruiz

Hey, all.. I need to be able to log in to my production image with VNC until i am comfortable with the command line interface. I know that every time i have had to do it, it seems like i used a different package. Which package is everyone using these days for remote GUI access?

Re: [Pharo-users] Pharo on the SqueakJS virtual machine (was "PharoJS")

by Craig Latta

Hi Aik-Siong-- > Great news for Pharo. I presume it will be after you are done with > Squeak running on SqueakJS. 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. I also want Squeak and Pharo in web browsers to communicate with their native counterparts, and with other Smalltalks. My goal is a federation of live collaborating Smalltalk nodes on the net. I also have SqueakJS controlling and reprogramming NodeJS instances. > Do you have a roadmap? Bert and I worked on it a bit at ESUG 2016, and it was going alright. Very conservatively, I expect to have it finished this year sometime. > How will WebAssembly help or not with project? I think WebAssembly will enable us to run Cog, with the usual web security compromises. That's also something I'm interested in working on. It may make the SqueakJS virtual machine obsolete. thanks, -C [1] https://caffeine.js.org [2] https://thiscontext.com -- Craig Latta Black Page Digital Amsterdam :: San Francisco craig(a)blackpagedigital.com +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)

Probably you forgot sudo apt-get install libssl1.0.0:i386 The following should be enough to run 32 bit pharo on 64 bit ubuntu sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install libc6:i386 sudo apt-get install libssl1.0.0:i386 sudo apt-get install libfreetype6:i386 > Thanks, > > Offray > > >

ZdcPluginMissing: SSL/TLS plugin initailization failed (VM plugin missing ? OS libraries missing ?)

by Offray Vladimir Luna CÃ¡rdenas

Hi, I'm trying to deploy a small web app in Teapot, following the Enterprise Pharo documentation and so, using Pharo 4 in the server. Installation went fine, but when I try to actually use the app and I get this error: ZdcPluginMissing: SSL/TLS plugin initailization failed (VM plugin missing ? OS libraries missing ?) Looking at [1] I see that this is because Pharo VM is expecting to found libssl at some place. My server is a virtual Debian 6 64 bits, as provided by Digital Ocean. When I locate the missing library and make a symbolic link using: ln -s /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 /usr/lib/libssl.so.1.0.0 I still get this behavior: ldd libSqueakSSL.so linux-gate.so.1 (0xf7747000) libssl.so.1.0.0 => not found libc.so.6 => /lib32/libc.so.6 (0xf758b000) /lib/ld-linux.so.2 (0xf774a000) So, still is not finding the libssl.so. [1] https://stackoverflow.com/questions/12293670/zodiac-mail-sending-in-pharo-s… I don't know if this is related with running a 32 VM inside a Debian 64 bits distro, but running the chapter 2 example of the Enterprise Pharo, I have not any problem like this one, on the same virtual server while deploying the web app. How can I solve this? Thanks, Offray

Re: [Pharo-users] PharoJS

by askoh

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?
