Trouble running OSProcess on smalltalkCI for Windows/mingw
by Thiede, Christoph 30 Aug '21

30 Aug '21

Hi all, while setting up smalltalkCI for a project, I am having troubles getting OSProcess to run on a GitHub Actions runner for Windows. My test is as simple as: OSProcess waitForCommand: 'whoami' Which, normally, should print a small string to stdout and return after no longer than a few decisonds. However, in my smalltalkCI test for Windows, I just keep getting timeouts, even though the username is output correctly to the CI log. I am installing OSProcess using: MCMcmUpdater updateFromRepository: 'http://www.squeaksource.com/OSProcess' baseName: MCMcmUpdater defaultBaseName interactive: false. <http://www.hpi.de/> I have ensured (via good old Transcript debugging) that the grimReaperProcess is running and not suspended. Also, there is not any other error message visible in the Transcript. How could that be? As far as I know, the GitHub runner for Windows uses the git bash (mingw), so Windows executables and APIs are still available, but the shell is a different one. I could also reproduce the issue when running smalltalkCI from my local git bash (mingw). Interestingly, when using the "--headful" option to inspect the image manually, I can run all tests successfully, but when the tests are run automatically in the squeak::run_tests stage, they fail again. What is going on here?? At the moment, I feel somehow like at my wit's end ... Did anyone of you already encountered a similar problem, or do you have any idea how to debug/solve the problem? Thanks in advance! :-) Best, Christoph

Announcement: Spelling services
by Tim Felgentreff 23 Aug '21

23 Aug '21

Hi Once upon a time, John M. McIntosh built a spellchecker plugin for the MacVM and there was a fileout that added a spelling service class to use it from Squeak. We have added code to provide the same API (for now) to windows and linux users that have ispell (or a compatible program, like aspell) installed on their systems using system callouts. A metacello configuration is available from the MetacelloRepository on Squeaksource, ConfigurationOfSpellingServices. The development repository is at http://www.hpi.uni-potsdam.de/hirschfeld/squeaksource/SpellingServices.html, the repo has global read+write, so if anybody finds this useful and has changes, feel free to commit to that repository. -Tim

Debian tarball updates?
by tim Rowledge 13 Aug '21

13 Aug '21

Is anyone out there interested in, and able to spend the time, to try to sort out an update of the Debian tarball stuff? A long time ago we went through some considerable effort to get Squeak into the system and it seems to have languished ever since. It would make us look somewhat more contemporary if we could get an updated package built and inserted. Please, if you can help, let us know. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: RWD: Rewind Disk

generators
by Eliot Miranda 09 Jul '21

09 Jul '21

Hi All, I juts had occasion to use generators in anger for the first time. I was trying to fnd out why a clone of a prse tree was reporting that it was not the same tree. Generators made enumerating all nodes in each tree together trivial: | them | them := Generator on: [:g| newTree nodesDo: [:n| g yield: n]]. parseTree nodesDo: [:n| | twin | twin := them next. (n isSameAs: twin) ifFalse: [self halt]] My message though comes from noticing that generators yield their values via next, so why not use nextPut: instead of yield: ? e.g. I think this is better: | them | them := Generator on: [:g| newTree nodesDo: [:n| g nextPut: n]]. parseTree nodesDo: [:n| | twin | twin := them next. (n isSameAs: twin) ifFalse: [self halt]] _,,,^..^,,,_ best, Eliot
