Re: [Jprogramming] error with Graphviz on j807/j64/darwin

Dear David Mitchell, I upgraded graphviz and started graphview. In the graphview, File -> Open opens the Finder (similar to the Windows Explorer) at the folder ‚graphs' (at /usr/local/Cellar/graphviz/2.40.1_1/share/graphviz/graphs), so I can choose to select the „direct“ or the „undirected“ ex

Re: [Jprogramming] error with Graphviz on j807/j64/darwin

Dear Ulrich, Thanks for your help debugging this. It would not have been possible to fix the issue otherwise. I made one last change to select the Darwin sample graphs from the File->Open Menu. Please let me know if this works correctly. All the best, Mitch On 7/4/2019 14:02, Ulrich Volle

Re: [Jprogramming] error with Graphviz on j807/j64/darwin

Hi Ulrich, Yes, that would explain it. The simplest way around this is to do for Darwin what the Windows code does and ignore any path settings and specify the full path to dot in the call to spawn. This seems like a reasonable approach. I just updated the addon to do this. Please try it an

Re: [Jprogramming] error with Graphviz on j807/j64/darwin

Hi David, I looked for the source code of spawn which seems to be 2!:0@] I tried 2!:0 'pwd' Or 2!:0 'ls' Which work as expected. With 2!:0 'echo $PATH‘ I found out that there is a different path which is used by 2!:0, different from the path in the console window. Thi

Re: [Jprogramming] error with Graphviz on j807/j64/darwin

Hi Ulrich, It looks like the dot program did what it was supposed to do, but, for some reason, J thinks there was an error from spawn. I'll see if I can puzzle it out by reviewing the J source code. J does use different code for spawn on Darwin than on Windows or Linux. All the best, David

Re: [Jprogramming] error with Graphviz on j807/j64/darwin

Hi David, The file graphview.svg contains a svg-drawing: a circled letter 'a' pointing to a circled letter ‚b' which I added to my email, but the png-image was removed from my email. I assume that this svg-file is the expected answer. So, I assume that dot is working as expected and without e

Your message seems to be truncated. Does that mean that the .svg outoput file was created, but is empty? I have two other suggestions. You could try putting a space after the -o and before the file name. Also, you could try: ldd /usr/local/bin/dot to see if all needed libraries are availabl

Re: [Jprogramming] error with Graphviz on j807/j64/darwin

Brian, The original graphviz uses the LF as a flag to determine if the argument is a graph or a file name of a graph file. That is why you got the 'Reading file" error. I did not modify that behaviour in my updated version. Cheers, David Mitchell On 7/2/2019 14:58, Brian Schott wrote: I ca
