Manually, open Monticello browser, right click on the repo (if you have loaded the ConfigOf then the repo will be listed), click "open repository". Click the mcz file in the right pane of the repo browser, click "browse". You'll see the (not loaded) code in the resulting code browser and can attempt to adapt the FFI calls. > - And, of course, I'd be grateful if someone could point me into the right > direction of how to tackle with the above cdecl syntax with the new UFFI. https://files.pharo.org/books-pdfs/booklet-uFFI/UFFIDRAFT.pdf Also see my very simple demo: https://github.com/PierceNg/libffidemo HTH.

eval from the linux commandline

by test email

i need to eval an object from my linux commandline. I understand that clap-st is able to do this, but I can't seem to import it into pharo7, I suppose because of compatability reasons. Someone sent me this, but I can't seem to replicate the help screen. Is it because I'm on linux and he's on mac? prometheus:2018-12-20 sven$ ./pharo Pharo.image printVersion [version] 'Pharo7.0.0' 'Pharo-7.0.0+rc1.build.66.sha.0ff3a6c1c0f1d9b2876c50e19b790dd7bb926dd9 (64 Bit)' prometheus:2018-12-20 sven$ ./pharo Pharo.image --list Currently installed Command Line Handlers: loadHermes Loads the hermes files passed as parameter printVersion Print image version save Rename the image and changes file initializePackages Initialize packages and protocols from a given lists st Loads and executes .st source files config Install and inspect Metacello Configurations from the command line metacello Install and inspect Metacello Baselines/Configurations from the command line test A command line test runner Fuel Loads fuel files clean Run image cleanup get Install catalog projects from the command line (consult catalog at http://catalog.pharo.org) perform Perform given message on a specified class or global eval Directly evaluates passed in one line scripts

Strictly speaking, such URLs are incorrect and can't be parsed. I do understand that sometimes these URLs occur in the wild, but again, strictly speaking they are in error. The fact that browser search boxes accept them is a service on top of the strict URL syntax, I am not 100% sure how they do it, but it probably involves a lot of heuristics and trial and error. The parser of ZnUrl is just 3 to 4 methods. There is nothing preventing somebody from making a new ZnLoseUrlParser, but it won't be easy. > ----- > Cheers, > Sean > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html >

Yes, this works if you are assembling the URL, but several people presented the use case of processing URLs from elsewhere, leaving one in a chicken-and-egg situation where one can't parse due to the diacritics and can't escape the diacritics (i.e. without incorrectly escaping other things) without parsing :/ ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Text presenter autosave features

by Offray Vladimir Luna CÃ¡rdenas

Hi, While migrating Grafoscopio from Pharo 6.x to Pharo 7.x., I noticed that auto save for text fields is not enabled. Previously, when I wrote something in a text field, the dirty mark in the upper right corner appeared and if autoAccept was enabled, the text was automatically saved. Now with Pharo 7.x the dirty mark don't appear at all, and is not making any auto-saving. * I see that TextPresenter is the one who is responsible for such text objects. There is any minimal example I can use to test the proper behavior? * There is any way to use WelcomeHelp class to get a similar behavior? Thanks, Offray

FFI to UFFI

by TomaÅ¾ Turk

I started to play with ODBC package upgrade from Pharo 4.0 to 7.0 (http://smalltalkhub.com/mc/PharoExtras/ODBC) more or less as an exercise. As a smalltalk novice I stubmled to the challenge of, as it seems, an old FFI syntax. When I try to load the package into Pharo 7.02 on Windows, I get this error: I have two questions: - Is there any elegant way to successfuly load the package into Pharo 7 to get started with the code adaptation? - And, of course, I'd be grateful if someone could point me into the right direction of how to tackle with the above cdecl syntax with the new UFFI.

[CfP] DLS 2019 - 15th Dynamic Languages Symposium, co-located with SPLASH 2019

by Nick Papoylias

======================================================================== Call for Papers DLS 2019 - 15th Dynamic Languages Symposium Co-located with SPLASH 2019, October 22, Athens, Greece https://conf.researchr.org/home/dls-2019 Follow us @dynlangsym ======================================================================== Dynamic Languages play a fundamental role in todayâs world of software, from the perspective of research and practice. Languages such as JavaScript, R, and Python are vehicles for cutting edge research as well as building widely used products and computational tools. The 15th Dynamic Languages Symposium (DLS) at SPLASH 2019 is the premier forum for researchers and practitioners to share research and experience on all aspects on dynamic languages. DLS 2019 invites high quality papers reporting original research and experience related to the design, implementation, and applications of dynamic languages. Areas of interest are generally empirical studies, language design, implementation, and runtimes, which includes but is not limited to: - innovative language features - innovative implementation techniques - innovative applications - development environments and tools - experience reports and case studies - domain-oriented programming - late binding, dynamic composition, and run-time adaptation - reflection and meta-programming - software evolution - language symbiosis and multi-paradigm languages - dynamic optimization - interpretation, just-in-time and ahead-of-time compilation - soft/optional/gradual typing - hardware support - educational approaches and perspectives - semantics of dynamic languages - frameworks and languages for the Cloud and the IoT Submission Details ------------------ Submissions must neither be previously published nor under review at other events. DLS 2019 uses a single-blind, two-phase reviewing process. Papers are assumed to be in one of the following categories: Research Papers: describe work that advances the current state of the art Experience Papers: describe insights gained from substantive practical applications that should be of a broad interest Dynamic Pearls: describe a known idea in an appealing way to remind the community and capture a readerâs interest The program committee will evaluate each paper based on its relevance, significance, clarity, and originality. The paper category needs to be indicated during submission, and papers are judged accordingly. Papers are to be submitted electronically at https://dls19.hotcrp.com/ in PDF format. Submissions must be in the ACM SIGPLAN conference acmart format, 10 point font, and should not exceed 12 pages. Please see full details in the instructions for authors available at: https://conf.researchr.org/home/dls-2019#Instructions-for-Authors DLS 2019 will run a two-phase reviewing process to help authors make their final papers the best that they can be. Accepted papers will be published in the ACM Digital Library and will be freely available for one month, starting two weeks before the event. Important Deadlines ------------------- Abstract Submission: May 29, 2019 Paper Submission: June 5, 2019 First Phase Notification: July 3, 2019 Final Notifications: August 14, 2019 Camera Ready: August 28, 2019 All deadlines are 23:59 AoE (UTC-12h).

Re: [Pharo-users] ZnURL and parsing URL with diacritics

by PBKResearch

I recall seeing this trick when Sven published it, but I have never tried it. Trying it now, I get strange results. I entered: 'https://fr.wiktionary.org/wiki/pÃ©ripÃ©tie' asFileReference asUrl. And when I inspect the result, it is the address of a non-existent file in my image directory. I am using Moose 6.1 ( Pharo 6.0 Latest update: #60541) on Windows 10. This is not a current image, I know, but it is more recent than the date of Sven's post (Dec 2014). Has something changed since 2014? Incidentally, I tried the other trick Sven cites in the same thread. The same url as above can be written: 'https://fr.wiktionary.org/wiki' asUrl / 'pÃ©ripÃ©tie'. This works fine, and is neater than the alternative with explicit percent encoding which I currently use. So thanks Sean for pointing me to the thread.
