From 4477e84772a545b8998cf68fd87fa8177831155f Mon Sep 17 00:00:00 2001 From: David Brunow Date: Sun, 27 Jul 2025 16:22:52 -0500 Subject: [PATCH] feat: enhance error handling with specific error types and recovery suggestions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add GitError, ParseError, and ConfigurationError types with detailed recovery suggestions - Replace generic ParserError with specific ParseError types for better diagnostics - Enhance ConventionalCommit validation to reject empty types and descriptions - Implement smart error suggestion logic that avoids redundant suggestions - Update command error handling with proper stderr output and exit codes - Fix duplicate CHANGELOG.md entries 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CHANGELOG.md | 18 -- Package.resolved | 116 ++----------- Sources/GitClient/GitClient+Live.swift | 32 +++- Sources/GitClient/GitClient.swift | 28 +-- Sources/Model/ConventionalCommit.swift | 12 +- Sources/Model/GitError.swift | 31 ++++ Sources/Model/ParseError.swift | 20 +++ Sources/Model/RecoverableError.swift | 14 ++ .../Parser.swift | 24 +-- .../PullRequestCommand.swift | 39 +++-- .../ReleaseCommand.swift | 37 ++-- .../GitClientTests/GitClient+LiveTests.swift | 164 ++++++++++++++++++ .../ParserTests.swift | 116 ++++++------- .../ExecutionTests.swift | 1 + 14 files changed, 412 insertions(+), 240 deletions(-) create mode 100644 Sources/Model/GitError.swift create mode 100644 Sources/Model/ParseError.swift create mode 100644 Sources/Model/RecoverableError.swift create mode 100644 Tests/GitClientTests/GitClient+LiveTests.swift diff --git a/CHANGELOG.md b/CHANGELOG.md index 1220a68..2aa6c71 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -14,21 +14,3 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 * Setup CI for releases (9b70416) * Add CI (31581ad) -## [0.1.0] -
