CONTEXT_SOURCE ::= PREAMBLE "\starttext" TEXT "\stoptext" | CONTEXT_SOURCE
TEXT ::= STARTSTOPS | SETUPS | DEFINES | OTHERS [ TEXT
luigi:
To be general, i think
MY_CONTEXT_SOURCE ::= MACRO* END
R. Bastian:
I dont understand the sense of "\end\starttext"
sense==semantic "\end""\starttext" is a valid string for a hypothetical bnf grammar of ContTeXt which is not valid for your bnf ; "\end""\starttext""\stoptext" is in your bnf grammar and has the same semantic of "\end""\starttext" . The point is : a bnf for Context can be hard to define luigi: think that a bnf or lpeg grammar is really useful for a sort of
standard-ConTeXt or minimal-ConTeXt or light-ConTeXt ie a ConTeXt to use as "reference"
R. Bastian:
Exactly what I need : standard, minimal and light
Exactly what can be hard to define and capture in a bnf . wolfgang
How could a BNF grammar help to learn ConTeXt,
a bnf can help to build a syntax checker, a highlighter etc. Actually the only way to say that you have a valid ConTeXt string is running context on that string . The semantic is another story. -- luigi
