compressing register ranges

compressing register ranges

[Florian Grammel]

Using [compress=all] for registers yields somewhat puzzling results (1.0.4 (TeX Live 2017)).
I would expect the register of the following code to become one single range "1--7", though context produces "1--2, 3--7".
Is this the expected behaviour?
And if so: is there another switch to get the ranges to be collapsed completely?

Also: There wouldn't be a shorthand to define explicit ranges? LaTeX has \index{Demorange|(} to \index{Demorange|)} which is actually very convenient.

Best regards,
Florian.

ConTeXt has \startregister, see http://wiki.contextgarden.net/Registers#Collapse_Page_Numbers

I shoud probably have been more specific: While \startregister as such works for me, it 
	1) isn't collapsed as expected together with ordinary single register-entries (my main problem, cf mwe below)
	2) is a bit cumbersome to use as it requires the user to keep track of keys, as explained in your link from contextgarden.

Best,
Florian.
