Usage

Setup & Installation

Initial setup of the development environment:

# Install dependencies for the suite and all packages (production mode)
app::setup/install

# Install dependencies + local editable packages (development mode)
app::setup/install --env local

For a single package:

# Production: Install PDM dependencies only
.wex/bin/app-manager setup

# Development: Install dependencies + local editable packages
.wex/bin/app-manager app::setup/install --env local

Complete Development & Publication Workflow

1. Initial Setup (one-time)

# Install dependencies and local editable packages for development
app::setup/install --env local

2. Development Cycle

# Rectify code across all packages
app::file-state/rectify --all-packages

# Bump only packages with changes (excluding suite)
app::package/bump --packages-only --force

# Check for circular dependencies
app::dependencies/check

# Propagate versions across all packages
app::version/propagate --packages-only

# Commit and push all changes
app::package/commit-and-push --all-packages --yes

3. Publication

# Publish packages with changes to PyPI
app::suite/publish

File State Management

  • app::file-state/rectify [--all-packages]: Normalizes/rectifies code for a single app or across all packages in the suite; no commits.

Version Management

The version management commands use SuiteOrEachPackageMiddleware which provides flexible execution control:

  • Default: Executes on the suite (or single package if app_path points to a package)
  • --all-packages: Executes on both the suite AND all packages
  • --packages-only: Executes only on packages (excludes suite, implies --all-packages)
  • --suite-only: Executes only on the suite (excludes packages)

Commands:

  • app::package/bump [--all-packages|--packages-only|--suite-only] [--yes] [--force]: Bumps version for suite and/or packages. Use --force to bump only packages/suite with changes (no current version tag on HEAD).
  • app::version/propagate [--packages-only]: Propagates the current package version to other packages in the suite that depend on it. Use --packages-only to propagate all versions at once.

Git Operations

  • app::package/commit-and-push [--all-packages] [--yes]: Commits and pushes changes for a single package or all packages with uncommitted changes when using --all-packages.

Dependencies Management

  • app::dependencies/check: Validates internal dependencies across the suite to prevent circular dependencies.

Suite Execution

  • app::suite/exec-command -c <command> [--arguments "<args>"]: Executes a manager command on all packages (e.g., app::info/show).
  • app::suite/exec-shell -c "<command>": Executes a shell command on all packages.

Setup & Installation

  • app::setup/install: Installs PDM dependencies for the suite and all packages. Runs pdm install in the suite and each package.
  • app::setup/install --env local: Development mode - installs dependencies + all local packages as editable dependencies (pip install -e) for cross-package development.
  • .wex/bin/app-manager setup: Low-level command that runs pdm install for a single package (called by app-manager.sh).

Publishing

  • app::suite/publish: Publishes packages to PyPI. Only publishes packages with changes since their last publication tag. Automatically bumps versions, rectifies file state, commits, propagates versions, and publishes. Creates and pushes publication tags after successful publish.

Common Workflows

Setup development environment:

# Full development setup with editable packages
app::setup/install --env local

Bump only packages with changes (excluding suite):

app::package/bump --packages-only --force && app::version/propagate --packages-only && app::package/commit-and-push --all-packages --yes

Bump suite and all packages:

app::package/bump --all-packages

Bump only the suite:

app::package/bump --suite-only

Rectify all packages:

app::file-state/rectify --all-packages

Get info for all packages:

app::suite/exec-command -c app::info/show

API Reference

The wex-addon-app framework provides two distinct patterns for executing commands across package suites, representing an evolution from legacy inline iteration to a more modular, middleware-based approach.

Pattern 1: Middleware-Based Iteration (Recommended)

This pattern externalizes iteration logic from the command implementation, allowing commands to focus solely on their core functionality while middlewares handle the iteration concerns.

How It Works

Commands are decorated with middleware that can optionally iterate over packages:

  • AppMiddleware: Provides the base app_workdir context for a single application
  • EachSuitePackageMiddleware: Extends AppMiddleware and adds the --all-packages flag
    • When --all-packages is not specified: executes the command once on the target application
    • When --all-packages is specified: automatically iterates over all packages in the suite, executing the command on each package individually

Example: app::file-state/rectify

@middleware(middleware=AppMiddleware)
@middleware(middleware=EachSuitePackageMiddleware)
@command(type=COMMAND_TYPE_ADDON)
def app__file_state__rectify(
    context: ExecutionContext,
    app_workdir: BasicAppWorkdir,
    # ... other options
) -> None:
    # Command implementation focuses only on rectifying a single app
    # Iteration is handled externally by the middleware
    workdir.apply(...)

Usage:

# Rectify only the main suite application
.wex/bin/app-manager app::file-state/rectify

# Rectify all packages in the suite
.wex/bin/app-manager app::file-state/rectify --all-packages

Benefits:

  • Clean separation of concerns: command logic vs. iteration logic
  • Reusable middleware across multiple commands
  • Consistent iteration behavior
  • Easy to add iteration capability to existing commands

Pattern 2: Delegated Iteration (For Suite-Specific Commands)

This pattern is used when the command is inherently suite-oriented and always operates on multiple packages. The iteration is delegated to helper methods on the FrameworkPackageSuiteWorkdir.

How It Works

Commands use PackageSuiteMiddleware to ensure they receive a FrameworkPackageSuiteWorkdir, then delegate iteration to:

  • packages_execute_shell(cmd): Execute shell commands on all packages
  • packages_execute_manager(command, arguments, context): Execute manager commands (e.g., app::info/show) on all packages

Example: app::suite/exec-command

@middleware(middleware=PackageSuiteMiddleware)
@command(type=COMMAND_TYPE_ADDON)
def app__suite__exec_command(
    context: ExecutionContext,
    command: str,
    app_workdir: FrameworkPackageSuiteWorkdir,
    arguments: str = None,
) -> None:
    # Delegate iteration to the workdir helper
    app_workdir.packages_execute_manager(
        command=command,
        arguments=shell_split_cmd(arguments) if arguments else None,
        context=context
    )

Usage:

# Execute a manager command on all packages
.wex/bin/app-manager app::suite/exec-command -c app::info/show

# Execute a shell command on all packages
.wex/bin/app-manager app::suite/exec-shell -c "ls -la"

Benefits:

  • Explicit suite-wide operations
  • Centralized iteration logic in workdir helpers
  • Consistent error handling and progress reporting
  • Suitable for commands that only make sense in a suite context

Migration Guide: Legacy to Modern Patterns

Legacy approach (deprecated):

def old_command(context, app_path):
    suite = get_suite(app_path)
    for package in suite.get_packages():  # Iteration inside command
        # Do something with package

Modern approach (Pattern 1):

@middleware(middleware=EachSuitePackageMiddleware)
def new_command(context, app_workdir):
    # Iteration handled by middleware when --all-packages is used
    # Command only handles single app logic

Modern approach (Pattern 2):

@middleware(middleware=PackageSuiteMiddleware)
def suite_command(context, app_workdir: FrameworkPackageSuiteWorkdir):
    # Delegate iteration to workdir helper
    app_workdir.packages_execute_manager(...)

Choosing the Right Pattern

  • Use Pattern 1 (Middleware-Based) when:

    • The command can operate on both single apps and suites
    • You want optional iteration via --all-packages
    • The command logic is app-focused, not suite-focused

  • Use Pattern 2 (Delegated) when:

    • The command is inherently suite-oriented
    • Iteration is always required (no single-app mode)
    • You're executing shell commands or other manager commands on packages

Tests

This project uses pytest for testing and pytest-cov for code coverage analysis.

Installation

First, install the required testing dependencies:

.venv/bin/python -m pip install pytest pytest-cov

Basic Usage

Run all tests with coverage:

.venv/bin/python -m pytest --cov --cov-report=html

Common Commands

# Run tests with coverage for a specific module
.venv/bin/python -m pytest --cov=your_module

# Show which lines are not covered
.venv/bin/python -m pytest --cov=your_module --cov-report=term-missing

# Generate an HTML coverage report
.venv/bin/python -m pytest --cov=your_module --cov-report=html

# Combine terminal and HTML reports
.venv/bin/python -m pytest --cov=your_module --cov-report=term-missing --cov-report=html

# Run specific test file with coverage
.venv/bin/python -m pytest tests/test_file.py --cov=your_module --cov-report=term-missing

Viewing HTML Reports

After generating an HTML report, open htmlcov/index.html in your browser to view detailed line-by-line coverage information.

Coverage Threshold

To enforce a minimum coverage percentage:

.venv/bin/python -m pytest --cov=your_module --cov-fail-under=80

This will cause the test suite to fail if coverage drops below 80%.

Code Quality & Typing

All the suite packages follow strict quality standards:

  • Type hints: Full type coverage with mypy validation
  • Code formatting: Enforced with black and isort
  • Linting: Comprehensive checks with custom scripts and tools
  • Testing: High test coverage requirements

These standards ensure reliability and maintainability across the suite.
