From 824861c27c0f7429768f7320de3427d411dde388 Mon Sep 17 00:00:00 2001 From: Rogee Date: Mon, 22 Sep 2025 11:33:13 +0800 Subject: [PATCH] feat: Refactor AST generation routes workflow - Introduced a comprehensive data model for route definitions, parameters, and validation rules. - Established component interfaces for route parsing, comment parsing, import resolution, route building, validation, and rendering. - Developed a detailed implementation plan outlining execution flow, user requirements, and compliance with design principles. - Created a quickstart guide to assist users in utilizing the refactored system effectively. - Conducted thorough research on existing architecture, identifying key improvements and establishing a refactoring strategy. - Specified functional requirements and user scenarios to ensure clarity and testability. - Generated a task list for implementation, emphasizing test-driven development and parallel execution where applicable. --- CLAUDE.md | 24 + cmd/gen_route.go | 2 +- pkg/ast/route/builder.go | 302 ++++++---- pkg/ast/route/errors.go | 58 ++ pkg/ast/route/render.go | 137 ++++- pkg/ast/route/renderer.go | 187 +++++- pkg/ast/route/route.go | 408 ++++++++----- pkg/ast/route/route_test.go | 541 ++++++++++++++++++ pkg/ast/route/router.go.tpl | 36 +- .../contracts/route_builder_test.go | 239 ++++++++ .../contracts/route_parser_test.go | 261 +++++++++ specs/002-refactor-ast-gen/data-model.md | 387 +++++++++++++ specs/002-refactor-ast-gen/plan.md | 254 ++++++++ specs/002-refactor-ast-gen/quickstart.md | 353 ++++++++++++ specs/002-refactor-ast-gen/research.md | 137 +++++ specs/002-refactor-ast-gen/spec.md | 122 ++++ specs/002-refactor-ast-gen/tasks.md | 148 +++++ 17 files changed, 3324 insertions(+), 272 deletions(-) create mode 100644 CLAUDE.md create mode 100644 pkg/ast/route/errors.go create mode 100644 pkg/ast/route/route_test.go create mode 100644 specs/002-refactor-ast-gen/contracts/route_builder_test.go create mode 100644 specs/002-refactor-ast-gen/contracts/route_parser_test.go create mode 100644 specs/002-refactor-ast-gen/data-model.md create mode 100644 specs/002-refactor-ast-gen/plan.md create mode 100644 specs/002-refactor-ast-gen/quickstart.md create mode 100644 specs/002-refactor-ast-gen/research.md create mode 100644 specs/002-refactor-ast-gen/spec.md create mode 100644 specs/002-refactor-ast-gen/tasks.md diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 0000000..b52c034 --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,24 @@ +# atomctl Development Guidelines + +Auto-generated from all feature plans.
