user defined unit prints

[mhechthz]

I want to do something like this:

myval = ureg.Quantity(0.4,ureg.dimensionless,repr='[-]')
print("myval =",myval)

> myval = 4 [-]

myval2 = 5 * ureg.m / myval
print("myval2 =",myval2)
> myval2 = 5 m

is this possible somehow?

[-] would be the representation of dimensionless?

[mhechthz]

well yes. [] is usually for units, i.e. "power [MW]" and "-" is for "no unit". It's just for convenience since i use a lot of units like kWh, A,V, and then "dimensionless" takes a lot of space compared to the others. Only minus "-" would be also convenient. but basically i want to replace the default print name by a user text.
