I think it is possible, althought it can be better to do it through a
shell script.
Not sure about this, but you could do something like that:
' some code to determine if a new version is available
shell "cd /tmp; wget http://your.server/updates/your-program.gambas";
WAIT
shell "mv /tmp/your-program.gambas /usr/local/bin/" ' this rewrite
the old executable
shell "/usr/local/bin/your-program.gambas &" ' two
instances of the same program...
quit
This snippet relies on a possibility that only *nix has - to [re]write a
file while it is still in use (if it is).
Don't know if gambas interpreter keeps the file open while executing,
but this should be ininfluent.
With the "shell ....&" you launch a second instance of the same program,
which will be the updated file (bytecode).
Then the current application terminates.
There is a moment where two instances of the same application run
concurrently, so
open files, or other system-wide resources, must be closed before doing
that.
This is an overall idea - but it should work.
