Indeed, I would like to make NONE of them case insensitive. But currently, when I register an upper case key (C=coulomb) it messes up the lower case prefix (“cm" gets typeset as C•m). I was expecting the parser to distinguish between the “C” and “c”, but it doesn’t. Is that intended?
Indeed, \unit{} should allow (and presently does not) K, C, etc.
I agree. I added the following lines to phys-dim.lua, following line 461 C = "coulomb", K = "kelvin", N = "newton", This provided the desired capital shortcuts without compromising the lowercase prefixes. Hans, could we get those added to phys-dim.lua in the distribution? I would be happy to do a more comprehensive search for shortcuts to add, but those are the three I and my collaborators are using now. Looking at why my \registerunit attempt failed, I found that when you register a unit, both your capitalization, and an all lowercase version are registered. Here is an example, where I register “ReTeM” but \unit{1 retem} also works. \starttext \registerunit[unit][ReTeM=myunit] \setupunittext[myunit=reTeM] \startformula \unit{1 ReTeM} = \unit{1 retem} \neq \unit{1 reteM} \stopformula \stoptext The results are case sensitive, so \unit{1 reteM} does not work. The lowercase version is produced for all “long” units, but not for shortcuts. (See phys-dim.lua, lines 766-771 where the Lua string function “lower” is used.) Perhaps we could use a \registershortcut command that does not get the “lower" treatment. I will look into it some more. Thanks! Gavin P.S. I think there is a spelling error in phys-dim.lua, lines 974-981. local mapping = { prefix = "prefixes", unit = "units", operator = "operators", suffixe = "suffixes", symbol = "symbols", packaged = "packaged", } The key “suffixe” should probably be “suffix”.
