This example shows how to parse source code in the D programming language using DParserGen. The grammar for D is in file grammard.ebnf, which uses rules for the lexer from file grammardlex.ebnf. File grammarddoc.ebnf also contains a grammar for DDOC, which is used to extract the grammar from the source of dlang.org using grammardgen.d.
Example testgrammard.d uses a parser and a lexer generated from grammard.ebnf and grammardlex.ebnf to parse D files.
The application can be built with the following command:
dub buildThe following command runs the application with the source file as input:
./example_d testgrammard.dDifferent options also allow to test the grammar on the test suite of DMD and other folders with source code.
