<p><b>New page</b></p><div><br />
A grammar which rules do not depend on the context during parsing. I know, this is a circular definition.<br />
<br />
Here are some examples :<br />
<br />
* Lojban's grammar, and more generally any [[jbocre: LR|LR]] or [[jbocre: LL|LL]] grammar, are context-free.<br />
<br />
* The C language is supposed to be context-free, except on the topic of type definition (if "typedef" preceeds a definition, the symbol defined becomes a type rather than a variable : semantics change depending on the context, given the same lexical grammar).<br />
** C is fairly good about it, compared to many other languages.<br />
<br />
* English is not context-free. The way we parse/understand sentences depends on the context, either past or future. Consider this text :<br />
<br />
you if sense makes sentence this, please read the first six words backwards.<br />
<br />
*''mi'e cein. Doesn't Lojban have si/sa/su, which must be "understood" by the parser in the same sense as the English example above in order to be correctly parsed?''<br />
** maybe this doesn't address what you mean -- but si/sa/su can be implemented below actual language parsing, simsa things such as \ line continuations in C.<br />
<br />
** they are trivially handled by the lexer.<br />
*But this sentence isn't legitimate English...<br />
<br />
** arguable; but the point still stands -- english isn't context free. A phrase structure grammar for english would be hideously large and type 0-1, if a complete one were ever made, which is unlikely. --mi'e .djorden.<br />

Fairly sure that is the case. It would certainly be context. --[[jbocre: Jay Kominek|Jay]]<br />

the above is correct -- a context free grammar may only have one non terminal on the left hand side of its rules. --mi'e .djorden.</div>
