LaTeX BNF

[Chris Cliffe]

I am a final year student at Coventry University and am undertaking a
project to produce a LaTeX Editor (I know such things exist, but the
project is a learning exercise).

As part of the editor, a parser will parse the LaTeX file to detect any
errors in the syntax. I am therefore trying to find a BNF (Backus-Naur
Form) description of the LaTeX syntax.

Thanks for any help,

I don't think that BNF is a good way to express TeX syntax.
There is almost no grammar, and grammar is what are BNF for.

It sounds much like "Tcl BNF, m4 BNF or Forth BNF"

Try to get some existing TeX checker (there are several on CTAN) and
adopt for your project. Or write a parser directly from what is given
in TeXbook.
