EbnfStudio is a development environment for EBNF files which supports syntax highlighting, inline warnings, symbol navigation and cross-referencing. The grammar is automatically analyzed for syntax errors, missing non-terminals and left recursion while editing. The grammar can also be checked for LL(1) ambiguities and the effectiveness of conflict resolvers. EbnfStudio allows to keep grammars implementation-free; this also applies to the conflict resolvers which are terminals of the form \LL:k\ with k > 1. The current implementation supports the generation of input files to the Coco/R, LLnextgen and ANTLR parser generators, but currently conflict resolvers and the automatic generation of syntax trees are only supported for Coco/R.
