<![CDATA[UDL: Number groups with negatives]]>Hello,

I am currently creating a UDL. The language represents sets of numbers using a / separator, such as 0.674/1.4695/2.4317.

Highlighting works for groups such as 0.674/1.4695/2.4317 or -0.674/1.4695/2.4317. However, highlighting stops when - is in the middle, like 0.674/-1.4695/2.4317. Does anyone know why this is the case? Thank you!

The language represents sets of numbers using a / separator

That doesn’t necessarily mean that / needs to be considered part of the number.
In that situation, I would define / as an operator, not part of Number: Extras 1. And, in fact, I would then remove the / - . completely from Extras 1, because . and - are already considered part of a number. And remove the digits from Prefix 2.

That renders your three examples reasonably, IMO:

If you absolutely have to have the / between the numbers in the same color as the numbers and a different color than your other operators, I would then bring in the plugin EnhanceAnyLexer, where you could define a regex to color the / in that special circumstance for your UDL – something like 0xA8CEB5 = (?<=\d)/(?=[\d-]) should work:
