[NTG-context] Re: get measures as dimension in Lua

Thank you, Max, for the effort and Hans for a core solution!

Indeed we can have:

local namespace = tokens.getters.macro("??measure")

function tex.getmeasure(name,asdimen)         local value = tex.getdimensionvalue(namespace..name)         if asdimen then             return value .. "sp"         else             return value         end

and when you want to avoid the namespace you can do:

function tex.getmeasure(name,asdimen)         local value = token.getexpansion("\tointeger\measured{"..name.."}")         if asdimen then             return value .. "sp"         else             return tonumber(value)         end     end

which is some 4 times slower. It'sindeed not documented (although there are some examples in accessors-001.tex) but it's in one of my todo's because I can use it in some places (there ar emopre such todo's) after which it will be discussed in one of the lowlelvel manuals

i'll add tex.getmeasure to the core (but a bit different)

Not to be misunderstood, I couldn’t check yet, maybe I wasn’t clear:

I need to process the measure as a dimension, like \measured{Bleed}.

As far as I tried, neither tex.measured nor context.measured worked (but I wouldn’t swear on it, maybe I had a different error).
