musing on StackInterpreter FreeRTOS VM target
by Ben Coman July 12, 2018

July 12, 2018

Just sharing something thats been circling my head for a while about a possible OpenSmalltalk based IoT platform. Many micro-controllers support FreeRTOS https://www.freertos.org/RTOS_ports.html including the ARMv7 https://www.freertos.org/FreeRTOS_Features.html and the ESP32 (based on Cadence's Tensilica Xtensa LX6) https://www.espressif.com/en/media_overview/news/espressifs-esp32-support-a… Of particular interest is Amazon's adoption of FreeRTOS and its change of license from GPLv2 to MIT. https://aws.amazon.com/blogs/opensource/announcing-freertos-kernel-v10/ If a "thing" is not doing graphics, then the StackInterpreter may be sufficient for many IoT applications. Having a FreeRTOS build target for the StackInterpreter might open the opportunity to have our Images running as the *only* application on a wide variety of embedded systems. A tight Edit-Compile-Run-Debug cycle using the TelePharo remote tools might be very compelling versus the usual Edit-Compile-Download-Boot-Run-BlindGuessDebug cycle. I'd expect interest that starts with the hobby-maker community, might later extend into the lucrative industrial control market in competition with traditional PLCs. Maybe getting the StackInterpreter running on a new platform could make a good advanced-student project? For starters, there seems a simulator here (I haven't used it) https://www.freertos.org/FreeRTOS-simulator-for-Linux.html which raises one question... I understand the VM has a problem with some simulators but is that more a problem for the JIT part of Cog than the StackInterpreter? cheers -ben

Tonel class comments
by Guillermo Polito July 11, 2018

July 11, 2018

Hi all, Since people have been asking how to use Tonel, I've took a look at it and have written down two class comments for both the reader and the writer. I'll push them to Tonel and schedule soon a patch release with it. Here are the class comments so people can see them/discusses them. Please, report any enhancements as pull requests in git@github.com:pharo-vcs/tonel.git ! TonelReader I'm a monticello reader for tonel format repositories. I read - a package per directory - a class per file - a set of extensions to a single class per file (for example, all extensions of a package to String will be in a single file) I'm created on a file reference to a directory where the package will be read and the name of the package to read. [[[ TonelReader on: 'someDirectoryWithTonelPackages' asFileReference filename: 'MyPackageName' ]]] My main method is - ==#definitions== reads and parses the tonel file, returns a list of monticello definitions. - ==#snapshot== returns a monticello snapshot with the read definitions. - ==#version== returns a monticello version with the read snapshot. !! Implementation details The monticello versions I return do have artificial information. Since I'm just meant to read versions from a directory, this directory has no information such as commit message, commit time, author, or ancestors. Check the method ==#loadVersionInfo== for more information. ! TonelWriter I'm a monticello writer for tonel format, writing - a package per directory - a class per file - a set of extensions to a single class per file (for example, all extensions of a package to String will be in a single file) I'm created on a file reference to a directory where the package will be written. [[[ TonelWriter on: ('someDirectory' asFileReference ensureCreateDirectory) ]]] My main methods are - ==#writeVersion:== that receives as argument a monticello version to write, from where I'll extract the corresponding monticello snapshot. - ==#writeSnapshot:== that receives as argument a monticello snapshot to write, from where I'll write all the contained definitions. !! Implementation details Notice that while writing, if the written package/snapshot already exists in the directory I'll overwrite it (i.e., remove it and recreate it). -- Guille Polito Research Engineer Centre de Recherche en Informatique, Signal et Automatique de Lille CRIStAL - UMR 9189 French National Center for Scientific Research - *http://www.cnrs.fr <http://www.cnrs.fr>* *Web:* *http://guillep.github.io* <http://guillep.github.io> *Phone: *+33 06 52 70 66 13

Which command-line handlers do you use most?
by Damien Pollet July 10, 2018

July 10, 2018

Hi all, I'm starting to port / reimplement existing command line handlers using Clap. There's a dozen, but I wonder which ones are the most relied upon, because it's a good opportunity for refactoring the command line API as a whole and simplifying it or at least making it more orthogonal. For instance I discovered there is a "perform" command, which is sort of redundant with the "eval" one. Similarly there are both a "configuration" and a "metacello" handlers which seem to have the same exact purposeâ¦ Since Clap can exist besides the current command-line handlers, we can have a deprecation period to minimize breakage and leave time for people to adapt before we kill old command line handlers for real. -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet
