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”.
