Hello,
I'm using Hans' macro suggested some time before.
I've just updated Ctx MkIV and my sample code:
----
\starttext
\def\MyMacro{Ahoj}
\def\MyMacWithPars#1#2{Something}
\def\Undefined{}
\let\Undefined\undefined
\def\DoNothing{}
\let\DoNothing\donothing
\startluacode
if CONTEXTLMTXMODE == 0 then
local d = tokens.defined
local c = tokens.create
function tokens.defined(s,b)
if b then
return d(s)
else
return c(s).cmd_name == "undefined_cmd"
end
end
end
--
local defined = tokens.defined
for _, v in ipairs{ "MyMacro", "MyMacWithPars", "Undefined", "DoNothing",
"NonExisting" } do
print(string.format("\letterpercent-12s", v), defined(v), defined(v,
true), defined(v, false))
end
\stopluacode
Aaa
\stoptext
as you updated, it's just:
\startluacode
local defined = tokens.defined
for _, v in ipairs{ "MyMacro", "MyMacWithPars", "Undefined",
"DoNothing", "NonExisting" } do
print(string.format("\letterpercent-12s", v), defined(v),
defined(v, true), defined(v, false))
end
\stopluacode
