A problem with units

A problem with units

[Marcin Borkowski]

Hi all,

being quite happy with things like \unit{10 km/h}, once I did \unit{45
min}, only to get "45 m" in the resulting file.  I suspect that \unit
does not know about minutes; is there any way to teach it;)?

Best,

I think 'min' is parsed as 'meter nil nil', because (1) min is not
found in the list of short or long unit names, so it's assumed to be
composite; and (2) once processed composite, m-->meter-->m, while
i-->nil and n-->nil.
Solution: add 'min' to the list of short unit names (below).

Cheers,
Sietse

% phys-dim.lua

local short_units = { -- I'm not sure about casing

    m  = "meter",
    Hz = "hertz",
    hz = "hertz",
    B  = "bel",
    b  = "bel",
    lx = "lux",
 -- da = "dalton",
    h  = "hour",
    s  = "second",
    g  = "gram",
    n  = "newton",
    v  = "volt",
    t  = "tonne",
    l  = "liter",
 -- w  = "watt",
    W  = "watt",
 -- a  = "ampere",
    A  = "ampere",
+    min = "minute",

    [utfchar(0x2103)] = "celsius",
    [utfchar(0x2109)] = "fahrenheit",
}

One can add units with \registerunit[unit] and \setupunittext (see line 652 in 
phys-dim.mkiv):

\starttext
\registerunit
  [unit]
  [minute=minute]

\setupunittext
  [minute=min]

\unit{45 minute}
\stoptext

However, I'm unable to explain what exactly \registerunit or \setupunittext 
does.

Hi Hans,

since you are working on the \unit code at the moment, I want to
remind you about an issue I reported a while ago.

Any thoughts on that one?
