Reify RBLiteralNode and RBBlockNode args/return with MetaLink?

by Manuel Leuenberger

Hi, I am currently playing with MetaLinks in Pharo 7 and stumbled upon some issues. For example, I found that instrumenting message sends may break compilation (see https://pharo.fogbugz.com/f/cases/22681/Metalink-on-message-may-break-compi… <https://pharo.fogbugz.com/f/cases/22681/Metalink-on-message-may-break-compi…>). Two other issues also arised: i) How do I reify the value of an RB(Valuel|Literal|LiteralValue)Node? RFValueReification does not work, and there is no reification for literal, value, or literal value nodes. ii) How do I reify arguments and results of blocks? I tried reify context for the block body #before and value for #after block "last", but I often run into the problem of no reification for literals. iii) How are cascaded message sends reified? Am I supposed to instrument the cascade node or the individual message sends? I am grateful for any pointers towards a solution. BTW, Marcus' lecture slides give a great intro to metalinks (http://marcusdenker.de/talks/18LectureMetaLinks/MetaLinks.pdf <http://marcusdenker.de/talks/18LectureMetaLinks/MetaLinks.pdf>). Cheers, Manuel

I am switching to GitHub, I did not yet come around to doing an older stable version. I'll try to do one later, but I am not yet finished with all the changes that I want to do.

Re: [Pharo-users] My Keynote at the Salta Conference

by horrido

That doesn't work for me. First of all, my programming competition has a strong marketing component. I cannot see how to market Smalltalk effectively through AoC. My Salta keynote made this very clear. AoC is unfocussed. It's not language-specific. It's basically all over the place. Second, I envision making the competition public knowledge in the (Canadian) media. Again, I don't see how that's possible with AoC. The competition includes promotional T-shirts. These shouldn't be linked with AoC. I have $25,000 and I'm not going to donate it all to AoC. That's practically no bang for the buck in terms of marketing. philippeback wrote > A good way to do this is to align it with Advent of Code 2018. > > AoC is actually full of interesting challenges and one can do private > leaderboards. > > This will also put Pharo on the AoC map/subreddit where challenges are > discussed. > > Phil > > On Sun, Nov 18, 2018, 15:29 Richard Kenneth Eng < > horrido.hobbies@ > wrote: > > > Some of you may already be aware of my presentation at *Smalltalks > 2018*, >> the outcome of which was full funding for my Smalltalk programming >> competition.

A good way to do this is to align it with Advent of Code 2018. AoC is actually full of interesting challenges and one can do private leaderboards. This will also put Pharo on the AoC map/subreddit where challenges are discussed.

My Keynote at the Salta Conference

by Richard Kenneth Eng

Some of you may already be aware of my presentation at *Smalltalks 2018*, the outcome of which was full funding for my Smalltalk programming competition. See My Keynote at the Salta Conference <https://hackernoon.com/my-keynote-at-the-salta-conference-435dfaccc888>. Three years ago, David Buck provided an outline for the competition. See attached. I would like to use that as a starting point, though I am open to alternative suggestions. The reason for this post is the following... I need volunteers to code the competition. I am nowhere near qualified to do so, as my knowledge of Pharo is limited. Without help from Pharoers (or, at least, Smalltalkers), the competition is in jeopardy. This is a great opportunity to promote Pharo. (The original competition three years ago was going to use VisualWorks, but since Cincom did not see fit to support my competition this year, I decided to go with Pharo.) Please contact me if anyone is interested. It would be a terrible shame to waste this opportunity. Regards, Richard

The ffiCall:module: message always gives me "External module > not found". I use the library myself on 32-bit Pharo 6, so it works, for me at least. For custom so/dll files such as this library or my custom-built SQLite library, my practice is to place them into the VM directory where the Pharo executable and all its bundled so/dll files are. Then I run following script to start Pharo: #!/bin/sh PHAROVMPATH=$(dirname `readlink -f "$0"`) LD_LIBRARY_PATH="$PHAROVMPATH" exec "$PHAROVMPATH/pharo" $@ & Pierce

Re: [Pharo-users] External module not found

All is good now. I replaced my 64-bit Debian with 32-bit Debian. Then, I installed 32-bit Pharo. It's weird that I must run Pharo (which is installed in /home/richard) as root, though. Must be a Debain thing 'cuz it wasn't necessary in Ubuntu. Stephan Eggermont-3 wrote > horrido < > horrido.hobbies@ > > wrote: >> That's what I'm trying to determine.

Yes, of course. It's $home (/home/richard/pharo). Alistair Grant wrote > On Sun, 18 Nov 2018 at 04:55, horrido < > horrido.hobbies@ > > wrote: >> >> I just discovered why!
