Hi John, Thanks for the report! It seems we weren't lexing '#error' yet (that's probably what is on line 59 in "/usr/include/complex.h", right? Otherwise send me the line 59). The newest version should detect #error properly (and also checks for ends of directives, and *.hpp/*.cpp). Talking about antlr4, it seems the AST is analyzed using the visitor pattern (that approach is also used in libclang) but NetBeans <= 8.2 expects the whole AST in memory, so it seems we have a long refactoring road ahead (all this after successfully migrating the CXXParser.g to antlr4, which reads >3300 lines long).

[DISCUSS] CND, cnd.antlr & cnd.apt on top of Antlrv4?
Hi all, As you may remember from previous threads, the NetBeans 8.2 "cnd.antlr" module contained a fork of Antlr 2.7.7 (compiler & runtime) that was not donated to the ASF. As a substitute Oracle donated a "cnd/libs.cnd.antlr" library wrapper that wrapped the NetBeans 8.2 jar, that we cannot use in Apache NetBeans due to licensing problems. The "cnd.apt" package contains an old "aptlexer.g" (on top of this Antlr 2.7.7 runtime) lexer grammar that is responsible for lexing C/C++ and Fortran files. I've done a small experiment (see [1]) transforming this old "aptexpr.g" grammar with 1403 lines [2] to a brand new "APTLexer.g4" lexer grammar [3] with 480 lines. This is still on early stages, but it seems the resulting Antlrv4 lexer outperforms the old Antlrv2 lexer (we go from ~2600 files/second to ~4000 files/second). I think we can continue the path of removing the old "libs.antlr.cnd" module from CND and then refactor "cnd.apt" (and "cnd.asm" et al) on top of the new lexer and Antlrv4. The idea is to upgrade all existing grammars (including the CXX parser at https://github.com/apache/netbeans/blob/cnd/cnd/cnd.modelimpl/src/org/netbeans/modules/cnd/modelimpl/parser/CXXParser.g) to Antlrv4 on top of this new lexer. Since the "libs.antlr.cnd" API permeates different modules of CND this may take quite a long time. I think we can create a brand new "cnd2" branch in the main repository (forked from the "cnd" branch and refreshed with latest 12.4 version) and do this CND refactoring on top of Antlrv4 there, right? Any objections to this? Or shall I continue this experiment in a repo of mine? Any other plans/suggestions to have CND back? Thanks, Antonio P.S.: In order to test the lexer I'd appreciate if you run the new lexer (instructions at [1]) on some of your include/source directories and report back any syntax errors you may see (the lexer will halt on any lexer error), so we can fine-tune any extra lexer rules we may need.
