[Octave-bug-tracker] [bug #60058] Feature request: function javaversion()

[Ernst Reissner]

Follow-up Comment #4, bug #60058 (project octave):

Great idea. Look at it: 
octave:17> version('-java')
ans = Java 11.0.10+9-suse-1.1-x8664 with Oracle Corporation OpenJDK 64-Bit
Server VM mixed mode
octave:18> compare_versions ('Java 11.0.5', version('-java'),'<=')
ans = 0
octave:19> compare_versions ('Java 11.0.05', version('-java'),'<=')
ans = 1

This is buggy as hell. 
I think if there is no spec whats the form of the version.. well... 
no trust. 


I would like to suggest an improvement over compare_versions: 
two arguments only 
Result is -1, 0,1 if < == >. 
With that you can implement the operators yourself in an obvious and elegant
way.
