This major release introduces new configuration options, improved error handling, and better performance. + +### 1. Enhanced Error Reporting with Line Numbers + +The v2.0.0 release significantly improves error reporting by providing line numbers and field names in error messages: + +``` +public class EnhancedErrorExample : IFileLine +{ + [Column(0)] + public string Code { get; set; } + + [Column(1)] + public NameType Name { get; set; } + + public int Index { get; set; } + public IList Errors { get; set; } +} + +// Usage - error messages now include line numbers and field details +var parser = new Parser('|'); +var lines = new[] { "GB-01|Invalid Name Format", "XX-99|Another Invalid Entry" }; + +var result = parser.Parse(lines); + +foreach (var item in result) +{ + if (item.Errors?.Any() == true) + { + Console.WriteLine($"Line {item.Index}: {string.Join(", ", item.Errors)}"); + // Example: "Line 1: Name failed to parse - Invalid name format in value 'Invalid Name Format'" + } +} +``` + +### 2. ParseOptions Configuration Class + +Introducing `ParseOptions` to configure parsing behavior with various options: + +``` +public class ParseOptions +{ + public char Delimiter { get; set; } = ','; // Default delimiter + public bool SkipHeaderLine { get; set; } = false; // Skip first line as header + public bool TrimFieldValues { get; set; } = true; // Trim whitespace from values + public bool IncludeEmptyLines { get; set; } = true; // Include empty lines in output + public int MaxErrors { get; set; } = -1; // Max errors to collect (-1 for unlimited) + public int BufferSize { get; set; } = 1024; // Buffer size for streaming operations +} + +// Usage examples +var customParser = new Parser(); + +// Parse with custom options +var options = new ParseOptions +{ + Delimiter = '|', + SkipHeaderLine = true, + TrimFieldValues = true, + IncludeEmptyLines = false, + MaxErrors = 100 +}; + +var result = await parser.ParseAsync("data.csv", options); +``` + +### 3. TryParse and TryParseAsync Methods + +New methods added for more explicit error handling using the result pattern: + +``` +// Synchronous TryParse methods +public Result TryParse(string filepath) where T : IFileLine, new(); +public Result TryParse(string filepath, ParseOptions options) where T : IFileLine, new(); +public Result TryParse(string[] lines) where T : IFileLine, new(); +public Result TryParse(string[] lines, ParseOptions options) where T : IFileLine, new(); +public Result TryParse(byte[] bytes, Encoding encoding = null) where T : IFileLine, new(); +public Result TryParse(byte[] bytes, Encoding encoding, ParseOptions options) where T : IFileLine, new(); +public Result TryParse(Stream stream, Encoding encoding = null) where T : IFileLine, new(); +public Result TryParse(Stream stream, Encoding encoding, ParseOptions options) where T : IFileLine, new(); + +// Asynchronous TryParse methods +public async Task> TryParseAsync(string filepath) where T : IFileLine, new(); +public async Task> TryParseAsync(string filepath, ParseOptions options) where T : IFileLine, new(); +public async Task> TryParseAsync(string[] lines) where T : IFileLine, new(); +public async Task> TryParseAsync(string[] lines, ParseOptions options) where T : IFileLine, new(); +public async Task> TryParseAsync(byte[] bytes, Encoding encoding = null) where T : IFileLine, new(); +public async Task> TryParseAsync(byte[] bytes, Encoding encoding, ParseOptions options) where T : IFileLine, new(); +public async Task> TryParseAsync(Stream stream, Encoding encoding = null) where T : IFileLine, new(); +public async Task> TryParseAsync(Stream stream, Encoding encoding, ParseOptions options) where T : IFileLine, new(); + +// Usage example with TryParse +var parser = new Parser('|'); + +// Safe parsing without throwing exceptions +var result = parser.TryParse("employees.csv"); + +if (result.IsSuccess) +{ + var employees = result.Value; + Console.WriteLine($"Successfully parsed {employees.Length} employees"); + + // Check for individual record errors + var validRecords = employees.Where(e => e.Errors?.Any() != true).ToArray(); + var errorRecords = employees.Where(e => e.Errors?.Any() == true).ToArray(); + + Console.WriteLine($"Valid records: {validRecords.Length}, Error records: {errorRecords.Length}"); +} +else +{ + // Global parsing errors occurred + Console.WriteLine($"Parsing failed: {result.Error}"); + foreach (var error in result.Errors) + { + Console.WriteLine($" - {error}"); + } +} +``` + +### 4. Result Pattern Implementation + +The `Result` class provides explicit success/failure semantics: + +``` +public class Result +{ + public bool IsSuccess { get; } + public bool IsFailure => !IsSuccess; + public T Value { get; } + public IList Errors { get; } + + public static Result Success(T value); + public static Result Failure(string error); + public static Result Failure(IList errors); + public static Result Failure(string error, IList errors); +} + +// Examples: +var successResult = Result.Success("Operation completed successfully"); +var errorResult = Result.Failure("File not found"); +``` + +### 5. Configuration Options Usage + +The new ParseOptions class allows for flexible parsing configurations: + +``` +// Example 1: CSV with headers, skipping first line +var csvOptions = new ParseOptions +{ + Delimiter = ',', + SkipHeaderLine = true +}; +var csvResult = parser.Parse("employees.csv", csvOptions); + +// Example 2: TSV with tab delimiter, no trimming +var tsvOptions = new ParseOptions +{ + Delimiter = '\t', + TrimFieldValues = false +}; +var tsvResult = parser.Parse("data.tsv", tsvOptions); + +// Example 3: PSV with pipe delimiter, limiting errors +var psvOptions = new ParseOptions +{ + Delimiter = '|', + MaxErrors = 50, + IncludeEmptyLines = false +}; +var psvResult = await parser.TryParseAsync("data.psv", psvOptions); +``` + +### 6. Backward Compatibility + +All v2.0.0 changes maintain complete backward compatibility: + +``` +// All existing code continues to work unchanged +var parser = new Parser('|'); +var employees = parser.Parse("employees.csv"); // Still works +var employeesAsync = await parser.ParseAsync("employees.csv"); // Still works + +// New functionality builds upon existing methods +var tryResult = parser.TryParse("employees.csv"); // New in v2.0.0 +``` + +### Migration Guide + +Upgrading from v1.x to v2.0.0 is seamless for existing code: + +1. **Existing code**: No changes required - all previous APIs remain the same +2. **New features**: Gradually adopt TryParse methods and ParseOptions for enhanced functionality +3. **Better error handling**: Switch to TryParse methods where more explicit error handling is needed + diff --git a/README.md b/README.md index d309abe..e2f67da 100644 --- a/README.md +++ b/README.md @@ -1,4 +1,4 @@ -# ninja Parsley.Net v1.1.5 +# ninja Parsley.Net v2.0.0 [![NuGet version](https://badge.fury.io/nu/Parsley.Net.svg)](https://badge.fury.io/nu/Parsley.Net) [![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://github.com/CodeShayk/Parsley.Net/blob/master/LICENSE.md) [![GitHub Release](https://img.shields.io/github/v/release/CodeShayk/Parsley.Net?logo=github&sort=semver)](https://github.com/CodeShayk/Parsley.Net/releases/latest) [![master-build](https://github.com/CodeShayk/parsley.net/actions/workflows/Master-Build.yml/badge.svg)](https://github.com/CodeShayk/parsley.net/actions/workflows/Master-Build.yml) @@ -48,12 +48,14 @@ If you are having problems, please let me know by [raising a new issue](https:// This project is licensed with the [MIT license](LICENSE). ## Version History -The main branch is now on .NET 9.0. -| Version | Release Notes | -| -------- | --------| -| [`v1.0.0`](https://github.com/CodeShayk/parsley.net/tree/v1.0.0) | [Notes](https://github.com/CodeShayk/Parsley.Net/releases/tag/v1.0.0) | -| [`v1.1.0`](https://github.com/CodeShayk/parsley.net/tree/v1.1.0) | [Notes](https://github.com/CodeShayk/Parsley.Net/releases/tag/v1.1.0) | +The main branch is now on .NET 9.0. + +| Version | Release Notes | +| ---------------------------------------------------------------- | -----------------------------------------------------------------------| +| [`v2.0.0`](https://github.com/CodeShayk/parsley.net/tree/v2.0.0) | [Notes](https://github.com/CodeShayk/Parsley.Net/releases/tag/v2.0.0) - MAJOR RELEASE: Comprehensive release with enhanced error reporting, improved performance, configuration options and result pattern | | [`v1.1.5`](https://github.com/CodeShayk/parsley.net/tree/v1.1.5) | [Notes](https://github.com/CodeShayk/Parsley.Net/releases/tag/v1.1.5) | +| [`v1.1.0`](https://github.com/CodeShayk/parsley.net/tree/v1.1.0) | [Notes](https://github.com/CodeShayk/Parsley.Net/releases/tag/v1.1.0) | +| [`v1.0.0`](https://github.com/CodeShayk/parsley.net/tree/v1.0.0) | [Notes](https://github.com/CodeShayk/Parsley.Net/releases/tag/v1.0.0) | ## Credits Thank you for reading.
