(Re)storing code blocks from text strings (hopefully in STON)

by Offray Vladimir Luna CÃ¡rdenas

Hi, I'm using STON for all my light storage serialization needs, like the Grafoscopio notebooks, and I also love it, as Russ stated in their mail question, and I share with him a similar request: for my Brea[1] static site generator I would like to store some BreaQuery objects as external STON files, and recover them, so I can run the queries that recreate/update the website easily. I could store them as Grafoscopio notebooks, but I don't want to make Grafoscopio a prerequisite for Brea or I could use Fuel, but I would like to store queries as a diff friendly text based format. I have considered Metacello/Iceberg packages to export code in a diff friendly format, but It maybe overkill. So I would like to see if STON can serve me here too. [1] https://mutabit.com/repos.fossil/brea/ [2] https://mutabit.com/repos.fossil/indieweb/ So far, I'm able to serialize a code block as a string using: BreaQuery>>asStonModified Â Â Â self codeBlock: self codeBlock asString Â Â Â ^ STON toStringPretty: self But I'm unable to populate a block from a string. There is any way to make a string, lets say 'a + b', to become the code contents of a block, ie: [a + b ] ? Thanks, Offray

Hi Martin, yes, it is true. I have to rollback the change because it was a compatibility issue with Debian 9.11, and this version is the one used by Jenkins docker images. I will do a release as soon as I can fix it. I want to push OBS to the last step to be productive. There is a lot of work on that and we need to profit it. The headless VM in Linux has been updated to the latest and that one has not been rollbacked.

Is this new VM available for Linux? I only see Windows and Mac VMs that are dated 2020-11-02. In the launcher (launcher 2.2, still the latest AFAICT) refreshing the 90-x64 VM just re-downloads the one from 2020-02-11.

Thank you for the explanation. I uninstalled Pharo and removed everything from AppData\\Roaming and Local and reinstalled Pharo and loaded willow-playground. I found everything in the system browser and was able to evaluate âSmalltalks2017Presentation startâ and bribg it up in my browser on port 8080.

The script is not going to produce nothing visually. You can see some progress bars during the loading depending on the time it takes to load and then the code should be available in the system browser.

Re: Willow-Playground

by g_patrickb＠yahoo.com

On my Windows 10 laptop I used image names of 80 and 90 and on OpenSUSE the image names were 80test and 90test. Thinking it may have to do with using numbers at the beginning of an image name I tried OpenSUSE again with an image name of Fish and it failed with the same error I originally had. I also tried on my Windows 8 desktop which has never had Pharo installed and used the defaults while installing. I created an 8.0 64-bit image named Fuzzy and it also failed with the same error.

I donât know what Iâm doing wrong. I get the same error on Windows 10 and OpenSUSE. On Windows I tried with and installation to C:\\Pharo and using an image name of 80 and 90; on Linux, the installation was to /home/gpb/ as the top level directory where it was unzipped.

by TomaÅ¾ Turk

I just tried to load Willow-Playground in the same way with Pharo 8.0 64-bit fresh image on Windows 10 and it works flawlessly. Seaside package has long filenames and directory names, on Windows this can be a problem if Pharo images are located deep in the hierarchy - but the error message in that case is usually different.

thanks Magritte is a chapter by itself in Seaside Book and also its mentioned in Stephane's booklet that Seside is shipped with Magritte so I assume that they are well integrated.

Hi I am posting here instead of the Magritte group as the readership is high. Is Magritte a robust enough package for an application with a large number of forms and sub forms. This is to be used in Pharo9 + Seaside +Willow. I am putting this question as i do not see much mention of Magritte in forums / discord of late, whereas by its description the package seems to fit a space for applications with many domain objects and associated forms. regards Sanjay ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
