First time Pharo experience: TFFIBackend induced crash...

by mylists＠posteo.de

Hi, (Running GENTOO Linux 64bit/no 32bit layer) I just downloaded the Pharo Launcer and followed the instructions given here: https://pharo-project.github.io/pharo-launcher/create-images/ I choose the newest stable image and launched it. A post mortem screen pops up (see attachment). Since I just started with Pharo Smalltalk, i can only guess, that something with the âTFFIBackendâ (whatever that isâ¦ ;) ) failed and Pharo stopped working. I would like to use Pharoâ¦ How can I fix that problem? Cheers!

Re: SmaCC: Adding conditions to production rules

by Thierry Goubier

Dear Konrad, the answer to your question is : it isn't pssoble as is in SmaCC (it breaks the underlying tcomputation heory). In practice, there are various ways to do so, depending on the kind of grammar you are building (and whether or not your grammar has conflicts). Cleanest way is to do a check at the end of the action (check that all <opidentifiers> are equal in the action, reject if this is not the case). You can use, if your grammar has conflicts, the GLR mode and select the right interpretation or reject the input. Another approach is to change the state of the scanner based on your actions, and so trigger the right production rule by emitting different tokens for example (such as a <sameOpIndentifier> following an <opIdentifier>. Again, different ways to do that; SmaCC offers an easy path to scanner specialisation that is fully compatible with SmaCC code generation (i.e. no fear to loose your customisation).

PDFtalk for Pharo - first fileOut

by christian.haider＠smalltalked-visuals.com

Hi Pharoers, as some of you know, there is a project on the way for porting the PDFtalk library from VisualWorks to non-namespaced Smalltalks [1]. Now, the first fileOut of the full PDFtalk library, including Values and tests, is available for Pharo [2]. The fileOuts should load into Pharo 10.0 (or 9.0, 8.0, 7.0 and 6.1) without errors. The files are about 5 MB in size and take around 6 to 10 minutes to load on my machine. There are lots of load warnings in the Transcript and many tests have errors, but all code loads and can be browsed and examined. The tool automatically rewrites namespaced names with prefixed globally unique names. This seems to work well and automates away much of the usual porting work. Now I am looking for a Pharoer with an interest in PDF and/or the transformation tool and some time at hand to pair up for some coding. This is an exiting project. Heads up - who wants to be part of this? Happy hacking, Christian [1] https://wiki.pdftalk.de/doku.php?id=pdftalknonnamespacefileout [2] https://wiki.pdftalk.de/doku.php?id=portingblog#first_fileout_of_the_full_pd ftalk_for_pharo P.S. I hope that I am writing to the right list - apologies, if this is spam for you

SmaCC: Adding conditions to production rules

by Konrad Hinsen

Hi everyone, I am stuck with a problem in SmaCC (of which I am a newbie user). Hoping for suggestions from experts, any kind of pointer is welcome! I have a production rule for infix operators: Term : NonInfixTerm 'arg' (<opIdentifier> 'opName' NonInfixTerm 'arg') * {{InfixOpTerm}} | NonInfixTerm ; According to the syntax rules of my language, infix terms are valid only if all <opIdentifier>s are equal. Otherwise parentheses must be used to disambiguate, as the language has no precedence rules. How can I do this with SmaCC? I don't see how I could do it using the basic features, but maybe with some tweaking on the Pharo side. Thanks in advance, Konrad.

Re: MIDI Interface?

by Stewart MacLean

Hi Antoine, For some reason your message below didn't come to me, I just "stumbled" across it. Thanks for the link to your work, it looks interesting. For now, I'm focused on the "plumbing", and this will be a great help with getting the FFI library going and I'll share my thoughts along the way! I've just started porting my dusty VisualWorks MidiAccessLayer that utilises PortMidi and RtMidi. Once I've got it in shape I'll be glad to share it with you. Cheers, Stewart Hello Stewart, Indeed I am working on PortMidi C library binding on Pharo. For now, the code I wrote contains an object that represents the C library and you can use its methods to try some MIDI stuff. I added several layers to these methods to make it easier to use. You can also create what I call scores which are sequences of notes and play them either separately or add them in an object called Prestation that is able to play several scores at the same time. You can find the code on GitHub : https://github.com/pharo-contributions/pharo-sound . Do not hesitate to tell me what you think about it !

One meta-issue is that some issues might be raised in Pharo, but should be raised in some sub-project (Spec, Iceberg, Microdown, â¦). I for one has been working mostly in Microdown, and would not obviously discover an issue regarding Microdown raised in the Pharo project. Perhaps it is just I who is sluppy.

Re: MIDI Interface?

by antoine.delaby＠inria.fr

Hello Stewart, Indeed I am working on PortMidi C library binding on Pharo. For now, the code I wrote contains an object that represents the C library and you can use its methods to try some MIDI stuff. I added several layers to these methods to make it easier to use. You can also create what I call scores which are sequences of notes and play them either separately or add them in an object called Prestation that is able to play several scores at the same time. You can find the code on GitHub : https://github.com/pharo-contributions/pharo-sound . Do not hesitate to tell me what you think about it ! Antoine

Please check older Issue tracker entries!

by Marcus Denker

Hi, One problem with a public issue tracker: it accumulates lots of issuesâ¦ This sadly means that issues will not be looked at one by oneâ¦ there are just too many. One thing that is interesting to do is to check the issue that *you* submitted. - Is the issue still relevant? - is the title good and in sync with the issue? - Has it been fixed already ? (it happens!) Then, for every issue there is a ânext stepâ. It can be a good thing to spell out very explicitly what the next step is âWe need to create a Pull Request for the suggested fixâ. Or maybe what is needed is a summary of the huge discussion in the issue tracker entry. Another idea: try to find others to help. E.g. - send a mail to the mailinglist. - ask on discord. Maybe you can find a small group that works on this issue together. Marcus

Re: Civic Tech, data activism and grassroots innovation for upcoming Colombian elections (Pharo/GToolkit powered)

by Offray Vladimir Luna CÃ¡rdenas

Hi Sebastian, Thanks for your words. We hope this project, even in alpha status, may showcase the potential that live coding and malleable systems have to empower new citizenship practices, starting from the elections and from there on, making sense of complex public data and elected/public officials. Regarding your questions, the code for Socialmetrica, our social media sense making project, is open source and you'll find it in [1] including the Roassal snippets and code for data acquisition, processing and storage. You'll notice we use Nitter[1a] unofficial API instead of Twitter one, because of all the bureaacracy and indifference we have experience from Twitter when trying to access its data. Also you will see that the sheets where made with LaTeX templates + Mustache injecting data from our domain objects into the LaTeX report, including Roassal3 png exports. Documentation is still in draft mode and mainly in Spanish, but we hope to publish some in the upcoming weeks. [1] https://code.tupale.co/Offray/Socialmetrica/ [1a] https://nitter.42l.fr/about Hope this helps and let us know if you have more questions regarding our code.

Hello Offray, This is s super nice work and also very important for the democracy. Is the code open source? I am particularly interested in the Roassal3 part. If possible, could you share all the Roassal3 code: how you create the sheets, the classes, the process between obtaining the data from an api, etc...

Civic Tech, data activism and grassroots innovation for upcoming Colombian elections (Pharo/GToolkit powered)

by Offray Vladimir Luna CÃ¡rdenas

Hi all, We have been working pretty hard lately to create data visualizations from the Twitter discourse of the candidates to the upcoming Colombian presidential elections. It's is an innovative approach combining live coding, reproducible research and data activism, narratives and visualizations. As usual, we try to simplify infrastructure to amplify/diversify participation. To produce our infographics we're using Roassal3 (except for the word cloud, because aesthetics reasons), RSS-Tools, XMLHtml parsers, ReStore and Mustache, among others. You can see more about this in this threads: [1] https://twitter.com/mutabit/status/1526272357425369094 [2] https://twitter.com/mutabit/status/1526235036458135553 We will be sharing more about this project and its behind scenes in the upcoming weeks. If you're instered, you can follow the hashtag https://twitter.com/hashtag/CandidatosEnDatos Retweets are welcomed and pretty appreciated. Cheers, Offray
