sipha-error

Error handling and diagnostics for sipha parsers.

Overview

sipha-error provides comprehensive error handling and diagnostic capabilities for sipha parsers:

ParseError: Enum with all parse error variants
Expected: Type for describing expected tokens
ErrorContext: Context tracking for error reporting
Diagnostic: Rich diagnostic types with miette integration (optional)

Features

default: Includes diagnostics feature
diagnostics: Enables rich error diagnostics with miette integration
color: Adds color support for error output (requires diagnostics)

Quick Start

Add sipha-error to your Cargo.toml:

[dependencies]
sipha-error = "0.1.1"

With diagnostics:

[dependencies]
sipha-error = { version = "0.1.1", features = ["diagnostics", "color"] }

Example

use sipha_error::{ParseError, Expected};
use sipha_core::{span::Span, traits::TokenKind};

#[derive(Copy, Clone, Debug, PartialEq, Eq, Hash)]
enum Token { Ident, Plus }
impl TokenKind for Token { fn is_trivia(&self) -> bool { false } }

let error = ParseError::Expected {
    expected: Expected::Single(Token::Ident),
    found: Some(Token::Plus),
    span: Span::new(0, 1),
    rule_context: None,
    context_stack: vec![],
};

#[cfg(feature = "diagnostics")]
{
    use sipha_error::Diagnostic;
    let diagnostic = Diagnostic::from_parse_error(&error);
    println!("{}", diagnostic.format_with_source("+ 5"));
}
