The Pattern that is used to match in - testVASmalltalkAddTimeAndVersion - testSqueakAddTimeAndVersion - testPharoAddTimeAndVersion - testGemstoneAddTimeAndVersion Did not take PUL into account. This works: '# From VisualWorks®*, * of * on * at *' * In the following tests, some selectors cannot be found: - testMethodAddsForValuemap - #_gs_printvalueWith: - testMethodAddsForObject - #_gs_Symbol_literalString - testWriteSystemExtensionMethods - #_gs_printvalueWith: Btw, I switched to SUnit to ease Porting to Pharo. I'll have a look into the #category parameter today. OT PDFtalk: Do you have plans to support verifying signatures in PDF files or singing using a certificate? Kind regards, Steffen Christian Haider schrieb am Mittwoch, 12. April 2023 21:07:05 (+02:00): Hi Steffen, thanks for trying and asking! I was loading the code needed into a 8.3, 64bit virgin image and realized that loading is not that straight forward and described too briefly. First, you need a non-default setting for the store prerequisites. I added this to the store access page: <https://wiki.pdftalk.de/doku.php?id=storeaccess> https://wiki.pdftalk.de/doku.php?id=storeaccess . It is critical to load the prereqs from store and not from parcels! The first thing to load is the bundle {Smalltalk Transform Project}. To see examples you need to load the subject of transformation: PDFtalk. You need to load to top bundle {PDFtalk Project} which includes the test classes you are missing in your image. At last, load the [Pharo Fileout PDFtalk] package. I improved the landing page <https://wiki.pdftalk.de/doku.php?id=smalltalktransform> https://wiki.pdftalk.de/doku.php?id=smalltalktransform a bit to make this clearer. I just tried and this loads without errors or warnings. (Actually good that the load did not work for you, because I added a mistake in January which causes a 8.3 image to crash when you open a browser. Sorry for that.) Now you should be all set for generating a fileout of PDFtalk for Pharo (in the current unfinished state). Thanks for spotting the problems with the documentation. I will get over it tomorrow. I am quick in renaming and making structural changes when things are not working as I want… But the docs should be correct, of course. About the project structure. Currently, everything belonging to a project, need to be transformed in one go. This is not a big deal, because all code transformations are described on the package level and can be easily recombined as the bundle structure changes. The last piece of the transformation puzzle is to make the transformations modular, so that the renamings of prerequisite packages can be used without the need to transform the prereqs as well. I hope to get at that soon… In the meantime, I would start with your Core project to get a feel for the mechanics. I am sure the rest will fall nicely into its places. About how to structure your code in Pharo with Git, I don’t know much about that. Actually, I would also be interested in some guidelines to bake them into the transformations… If you are seriously interested, we could have an online session to hack around with it… Cheers, Christian Von: Steffen Märcker <merk...@web.de <mailto:merk...@web.de> > Gesendet: Dienstag, 11.

I'll try to go through the process step by step and come back with questions to the list if that's okay. First, after loading the "Pharo Fileout PDFTalk", VW (8.3, 64 Bit) shows two unloadable definitions: - PostscriptInterpreterTests>>_ph_testOperatorNotFound - ColorValueTest>>_ph_testBridgedNamedColors Both classes are not loaded Second, it appears that some of the selectors mentioned on <https://wiki.pdftalk.de/doku.php?id=smalltalktransformdocumentation> https://wiki.pdftalk.de/doku.php?id=smalltalktransformdocumentation have been renamed, e.g., PackageChanges>>unusedClasses More general, regarding project structure. What is the best approach to port a project that consists of multiple loosely coupled packages (not in a bundle) some of which being optional? Like - Package Project Core - Package Project Core Tests (requires Core) - Package Project Extension A (requires Core) - Package Project Extension A Tests (requires Extension A) - Package Project Examples (requires Core and Extension A) And how should I structure this on the Pharo site and in an iceberg repository? One Git repository per package or all in the same? Is there a guide to this or a specific Mooc lesson? Kind regards, Steffen Christian Haider schrieb am Donnerstag, 6. April 2023 18:16:00 (+02:00): Yes, PDFtalk is the only example, because it was created to port that library. Any other uses are welcome. The project has been dormant for a year now because of other obligations, but I hope to resume soon. The documentation is, as Richard notes, in a suboptimal state. I think that the information is still accurate. Any help with this would be welcome, for example by asking questions or by criticizing concrete issues.

The only examples are various ports of PDFtalk (from VisualWorks) to Pharo, Squeak, GemStone, and VAST. PDFtalk is quite complex and the porting rules are correspondingly complex. The Transform documentation does leave something to be desired.

I want to port a number of packages to Pharo. I remember "Shaping" asking this for porting PDFtalk. 1. Is the workflow still up to date or is there a new way of doing things? 2. From what I understand so far, I just need the following package from Store: - Smalltalk Transform Project 3. Is there a page that documents the process process in general? <https://wiki.pdftalk.de/doku.php?id=setupvisualworks> https://wiki.pdftalk.de/doku.php?id=setupvisualworks seems to be specific for PDFtalk like the thread on this list.
