Why AnyRepair?

LLMs often generate malformed structured data. AnyRepair fixes common issues:

• JSON: Missing quotes, trailing commas, syntax errors
• YAML: Indentation issues, missing colons
• Markdown: Malformed headers, broken links
• XML/TOML/CSV/INI/Diff: Format-specific repairs

Key Features:

• ✅ Auto-detects format from damaged content
• ✅ Multi-format support (8 formats)
• ✅ High performance (regex caching, optimized binaries)
• ✅ MCP server for Claude integration
• ✅ Streaming support for large files
• ✅ 364+ tests, 100% pass rate

Usage Examples

Multi-Format Auto-Detection

use anyrepair::repair;

// JSON
let json = repair(r#"{"key": value,}"#)?;

// YAML
let yaml = repair("name: John\nage: 30")?;

// Markdown
let markdown = repair("# Header\n[link](url")?;

Format-Specific Repair

use anyrepair::{JsonRepair, YamlRepairer, MarkdownRepairer};

// JSON (Python jsonrepair-compatible API)
let mut jr = JsonRepair::new();
let repaired = jr.jsonrepair(malformed_json)?;

// YAML
let mut yaml_repairer = YamlRepairer::new();
let repaired = yaml_repairer.repair(malformed_yaml)?;

// Markdown
let mut md_repairer = MarkdownRepairer::new();
let repaired = md_repairer.repair(malformed_markdown)?;

Streaming Large Files

use anyrepair::StreamingRepair;
use std::fs::File;
use std::io::BufReader;

let input = BufReader::new(File::open("large_file.json")?);
let mut output = File::create("repaired.json")?;

let processor = StreamingRepair::with_buffer_size(8192);
processor.process(input, &mut output, "json")?;

MCP Server Integration

# Run MCP server for Claude
anyrepair-mcp

# Configure in claude_desktop_config.json:
# {
#   "mcpServers": {
#     "anyrepair": {
#       "command": "anyrepair-mcp"
#     }
#   }
# }

See MCP_SERVER.md for details.
