Dear list,
in the mwe below, the expected result is ok for most entries but fails
when the word contains the letters ó or ô.
We get zoolco instead of zoológico, and termtro instead of termômetro.
What am I doing wrong?
mwe:
\def\stripnumber#1%
{\cldcontext{lpeg.match(lpeg.stripper("[¹²³⁴⁵⁶⁷⁸⁹⁰]"),
[==[#1]==])}}
\starttext
\stripnumber{árbitro⁶}
\stripnumber{ébano¹}
\stripnumber{ícone⁸}
\stripnumber{zoológico⁰}
\stripnumber{eletroacústico⁹}
\stripnumber{trânsfuga⁷}
\stripnumber{farmacêutico¹}
\stripnumber{maître²}
\stripnumber{termômetro³}
\stripnumber{noûs⁴}
\stoptext
\def\stripnumber#1%
{\cldcontext{lpeg.match(lpeg.stripper(lpeg.US("¹²³⁴⁵⁶⁷⁸⁹⁰")),
[==[#1]==])}}
(US -> utf set)
or
\startluacode
local s = lpeg.stripper(lpeg.US("¹²³⁴⁵⁶⁷⁸⁹⁰"))
function document.StripNumber(str)
context(lpeg.match(s, str))
end
\stopluacode
\def\stripnumber#1{\ctxlua{document.StripNumber([==[#1]==])}}
or you can go fancy:
\startluacode
local p_strip = lpeg.stripper(lpeg.US("¹²³⁴⁵⁶⁷⁸⁹⁰"))
interfaces.implement {
name = "StripNumber",
public = true,
arguments = "string",
actions = function(str)
context(lpeg.match(p_strip, str))
end
}
\stopluacode
\StripNumber{zoológico⁰}
There are more efficient variants but i guess it's good enough.
