Subject: Re: Math letters in commands
Date: Mon, 12 Sep 2016 20:25:17 +0200 [thread overview]
Message-ID: <201FCE6F-7493-411A-A385-666BE69BB2E4@telia.com> (raw)

Found a workaround: The idea is to use \csname …\endcsname with two delimiters not likely to be used in math mode, below chosen to ‘…’.
But then there seems to be a bug in the LuaTex \letcharcode command: There must be a character between “$” and the first occurring \activecatcode letter. Possibly this also causes a bug in \startformula, as discussed before.
\setupbodyfont[xits,10pt]
\setupmathematics[lcgreek=normal, default=normal]
\def\usemathcommand#1’{\csname #1\endcsname}
\appendtoks
\catcode`‘=\activecatcode
\letcharcode `‘ \usemathcommand
\to \everymathematics
\definemathcommand[𝐝𝐢𝐦][nolop]{\mfunction{𝐝𝐢𝐦}}
\starttext
Note that $ ‘𝐝𝐢𝐦’ 𝑉 = 𝖫$, although $\dim 𝑉 = 4$.
And a bug: $‘𝐝𝐢𝐦’ 𝑉$.
\stoptext
