Any explanation?

Hello,

I encountered a weird error.

The following code prints correctly to the console:

---- \starttext \startluacode print("\n@T") \stopluacode

Abc \stoptext ----

Gives correct:

" ... fonts > virtual math > unable to resolve name mapsfromchar fonts > fallback modern rm 12pt is loaded

@T backend > xmp > using file 'c:/ConTeXt/tex/texmf-context/** tex/context/base/lpdf-pdx.xml' ... "

But the following code fails (?!):

---- \starttext \startluacode print("\nT") \stopluacode

Abc \stoptext ----

With:

" ... fonts > fallback modern rm 12pt is loaded ! Undefined control sequence.

system > tex > error on line 4 in file D:/Lukas/ConTeXt/Test/Env3/ **Test.mkiv: Undefined control sequence ...

1 \starttext 2 \startluacode 3 print("\nT") 4 >> \stopluacode 5 6 Abc 7 \stoptext 8

print("\nT ") \luat_start_lua_code_indeed ...tlua \zerocount {#1 }} l.4 \stopluacode ... "

Any explanation?

It's about catcode. You can the difference with \loggingall \startluacode context("\n@T") \stopluacode \stoptext and \loggingall \startluacode context("\nT") \stopluacode \stoptext -- luigi
