Is it possible to use the Unicode superscript and subscript parentheses as superscript and subscript operators? That is, ⁽…⁾ having the same function as ^{…}, and ₍…₎ as _{…}.
It might be something like the following, but somehow bundling the last part of \letcharcode into a command.
\appendtoks
\catcode`⁽=\activecatcode
\letcharcode `⁽ ^{
\catcode`⁾=\activecatcode
\letcharcode `⁾ }
\catcode`₍=\activecatcode
\letcharcode `₍ _{
\catcode`₎=\activecatcode
\letcharcode `₎ }
\to \everymathematics

I found using Unicode superscript and subscript parentheses more readable in general than the TeX convention in plain text. Otherwise, the program has logic as a basis, but is not intended to be restricted to that. FYI, the program is posted here, but has some dependencies to get running. The directory 'tests' has examples that are precompiled (checked agains with 'make check'). https://savannah.gnu.org/git/?group=metalogic-inference ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 8+ messages in thread

With direct bindings in LuaTeX it might be easier. —TeX syntax is good for writing by hand only. ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 8+ messages in thread
