Stability of the external plugin interface
by Philip Bernhart 25 May '20

25 May '20

Hello, I want to write an external plugin - I think, for having a fast interface to a C library. How is that currently done? How stable is that interface, will it change in the near future? What is the current best documentation for doing that? Is there an example plugin? Thanks for your time, Philip

State of the Lowcode integration?
by Philip Bernhart 24 May '20

24 May '20

Hi, I have noticed while reading the VM source, that there is this called lowcode and there is a paper about it at https://hal.inria.fr/hal-01353884/document What is the state of this vm extension? Is that available in Squeak or only in pharo? It seems to be linked into the build.win32x86/squeak.cog.spur.lowcode Thanks for your time, Philip

squeak in batch mode
by stes 09 May '20

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, I wonder whether there is a special class or mechanism to use Squeak in "batch mode". Suppose for example that you have a script: bash-4.4$ cat hello.sq TranscriptStream redirectToStdOut. Transcript show:'hello world'. Smalltalk quitPrimitive What seems to work - provided that the squeak.image has an open Transcript - then : /usr/bin/squeak squeak.image hello.sq > out or /usr/bin/squeak -headless squeak.image hello.sq > out writes 'hello world' to the file 'out'. It's an expensive way to do that, but it works, it launches squeak, and in the display one can see the Transcript doing show:'hello world', and then the image quits (with the 'quitPrimitive'). With the -headless option the image is doing the same thing without display. Two remarks: - this works in Squeak 4.6 4.16.7-3775 - for some reason this doesn't seem to work in Squeak 5.3 (at least for me, this may be due to my VM in 5.3 not working correctly or some other oversight) Is there perhaps a "BatchTranscript" class which is meant to be used for this? Or a module "batch" for using Squeak in batch mode ... Maybe I'm doing something wrong in V5.3 because I think a few days ago, it was working somehow also in 5.3 for me, not sure. Anyway if there were would exist some sort of BatchTranscript in SqueakMap or Monticello , that would help... Thanks!
