Static analysis for Pine Script ASTs.

pine-lint walks a parsed [pine_ast::Program] and reports likely bugs and non-idiomatic constructs as [Diagnostic]s. It is organized around three pieces:

• [Visitor] + the walk_* functions — the reusable traversal core.
• [LintPass] — one check; a visitor that collects diagnostics.
• [lint] — the driver that runs every registered pass over a program.

Example

use pine_ast::Program;
use pine_lexer::Lexer;
use pine_parser::Parser;

let src = "x = close == na\n";
let tokens = Lexer::new(src).tokenize().unwrap();
let program = Program::new(Parser::new(tokens).parse().unwrap());

let diagnostics = pine_lint::lint(&program);
assert_eq!(diagnostics.len(), 1);
assert_eq!(diagnostics[0].rule, "eq-na");
