in reply to ANSI C Parser in Perl?

Another approach is to let gcc do the parse for you, then load the result.

You can do this by running gcc on the source files with -fdump-translation-unit option. GCC::TranslationUnit can then be used to examine the parse tree.

From the GCC::TranslationUnit doco:

use GCC::TranslationUnit; # echo '#include <stdio.h>' > stdio.c # gcc -fdump-translation-unit -c stdio.c $node = GCC::TranslationUnit::Parser->parsefile('stdio.c.tu')->root; # list every function/variable name while($node) { if($node->isa('GCC::Node::function_decl') or $node->isa('GCC::Node::var_decl')) { printf "%s declared in %s\n", $node->name->identifier, $node->source; } } continue { $node = $node->chain; }
