Add a utility and/or library to dump a compact representation of a node? #182
Description
E.g. to tools or bin
This will help people who are developing libraries using this parser, as well as trying to debug the behavior on a given file/snippet.
I didn't see any similar issues mentioned elsewhere in the issues, readme, or tools directory.
Currently, I'm using this snippet: https://gist.github.com/TysonAndre/3c0619efc9695ef9f2465f4a55e6e6ee
Previously, I was using var_export(), which was several times longer.
» php dump.php "const X = 2*3+1;"
Node\SourceFileNode
statementList: Node\Statement\ConstDeclaration
constKeyword: Token: ConstKeyword(111): "const"
constElements: Node\DelimitedList\ConstElementList
children: Node\ConstElement
name: Token: Name(2): " X"
equalsToken: Token: EqualsToken(238): " ="
assignment: Node\Expression\BinaryExpression
leftOperand: Node\Expression\BinaryExpression
leftOperand: Node\NumericLiteral
children: Token: IntegerLiteralToken(416): " 2"
operator: Token: AsteriskToken(212): "*"
rightOperand: Node\NumericLiteral
children: Token: IntegerLiteralToken(416): "3"
operator: Token: PlusToken(213): "+"
rightOperand: Node\NumericLiteral
children: Token: IntegerLiteralToken(416): "1"
semicolon: Token: SemicolonToken(237): ";"
endOfFileToken: Token: EndOfFileToken(1): ""
EDIT: I've moved that snippet to https://github.com/phan/phan/blob/master/internal/dump_fallback_ast.php

Sort of related to what the syntax-visualizer does: https://github.com/Microsoft/tolerant-php-parser/tree/master/syntax-visualizer which is just running the parsed file through
json_encode
