Symbolic links in Pharo

Thibault ARLOING

Hi,


I want to create a symbolic link via Pharo.

But I don't know how, I found methods named #isSymlink but none for creation of symbolic links.


Can we create a symbolic link via Pharo ?

right now, you can’t… btw, even #isSymlink method is currently broken (I coded a replacement with UFFI but while making it work with linux I broke it with mac… and no time yet to finish it :( )
but I suppose also creating symlinks is something we can add soon :)

Ok, I will create my symbolic links with a bash script until it is available in Pharo 😊


Thanks

I guess you can do it with OSSubProcess shell command

Yes, I know but I want to use only Pharo classes because I don't want to add a dependency to OSSubProcess in my program


thanks anyway for your answer

You can use FFI; just create an object with a method…

MyObject>>system: command
"Perform OS system() call."

^ self ffiCall: #(int system #(char * command)) module: LibC


And then you can do something like

MyObject new system: 'ln -s /tmp/source /tmp/target'

So cool.
For a command taking some time to execute, can it be make non-blocking
for the image?

For example when using it from a Seaside server where you need to
execute such a command but you do not want to bock all the Seaside sessions.

Thanks

1) you can fork in the program you are launching
2) you can fork in the command you are launching… just like a regular shell (because that's what system() does) e.g.

MyObject new system: '{ sleep 5; touch /tmp/test.txt; } &'
