cc: Figure out a solution for AST debugging

[atirut-w]

It would seem that ANTLR Lab has been going through some shitstorm as of late. It first won't compile AST graphs, and now the website is entirely down. It's made me realize that a project like this will need a way to nicely visualize the AST without relying on ANTLR Lab.

Currently, the compiler has a --dump-ast option, but it's not human-readable by any means without some sort of post-processing or a custom dumper altogether. I dare you tell me this is immediately readable:

(compilationUnit (translationUnit (externalDeclaration (functionDefinition (declarationSpecifiers (declarationSpecifier (typeSpecifier int))) (declarator (directDeclarator (directDeclarator main) ( ))) (compoundStatement { (blockItemList (blockItem (statement (jumpStatement return (expression (assignmentExpression (conditionalExpression (logicalOrExpression (logicalAndExpression (inclusiveOrExpression (exclusiveOrExpression (andExpression (equalityExpression (relationalExpression (shiftExpression (additiveExpression (multiplicativeExpression (castExpression (unaryExpression (postfixExpression (primaryExpression ( (expression (assignmentExpression (conditionalExpression (logicalOrExpression (logicalAndExpression (inclusiveOrExpression (exclusiveOrExpression (andExpression (equalityExpression (relationalExpression (shiftExpression (additiveExpression (multiplicativeExpression (castExpression (unaryExpression (postfixExpression (primaryExpression 0))))))))))))))))) )))))))))))))))))) ;)))) })))) <EOF>)

Of course, I have zero experience in this regard, but making an issue like this can double as both a TODO and a sort of rep bounty.

Update: ANTLR Lab is now back online, but the point still stands.
