[Octave-bug-tracker] [bug #52488] genvarname substitutes underscore to invalid characters in string

[Rik]

Update of bug #52488 (project octave):

                Severity:              3 - Normal => 2 - Minor              
                Priority:              5 - Normal => 1 - Later              
                  Status:                    None => Confirmed

Follow-up Comment #1:

According to Matlab's documentation,


varname = genvarname(str) constructs a string or character vector varname that
is similar to or the same as the str input, and can be used as a valid
variable name.


The only requirements are that the name be "similar" and that the name is a
valid syntax for the interpreter.

Although Octave doesn't remove spaces as Matlab does, it does produce a valid
variable name that is "similar" to the original.  It meets the requirements of
the function genvarname, and I prefer the use of underscores as I think it
makes the generated names easier to read.  Imagine you have a variable name
that encodes something about a measurement in the name.


var = 'Site 1 laboratory 5 centrifuge 3 RPM';
genvarname (var)
Octave:
ans = Site_1_laboratory_5_centrifuge_3_RPM
Matlab:
ans = Site1laboratory5centrifuge3RPM


The Matlab name is very difficult to decipher.
