Hi, I encountered a problem with select() in beta-0.40.6-2009100509 (TeX Live 2009): ------------------------------------------------------------------ #! /usr/bin/env texlua print (select (1, string.gsub ('abc', 'b', 'X'))) print (select (2, string.gsub ('abc', 'b', 'X'))) ------------------------------------------------------------------ --> aXc 1 --> 1 This seems to be wrong. select (1, ....) should only return the first argument, not both. I'm wondering why select (2, ....) works as expected. I must admit that I couldn't find any specs for select(), it just appears in some examples in the Lua book. I can define select() myself, overwriting the built-in function. Then I get the results I expect: ------------------------------------------------------------------ #! /usr/bin/env texlua function select (n, ...) return arg[n] end print (select (1, string.gsub ('abc', 'b', 'X'))) print (select (2, string.gsub ('abc', 'b', 'X'))) ------------------------------------------------------------------ --> aXc --> 1 Bug or feature?
