Data package for Changelists CLI Tools

Changelist Data

Data Management for Changelists CLI Tools.

Usage Scenarios

This package is designed for the purpose of serving other changelist packages, and reducing code duplication.

Storage Scenarios

There are two storage options for Changelists.

• The first is the .idea/workspace.xml file associated with popular IDEs.
• The second is a dedicated .changelists/data.xml file managed by changelist-data on behalf of other changelist tools.

Each changelist tool must be compatible with both storage options. The goal of this package is to provide access to both storage options, and support the file reading and writing needs of all changelist tools.

Changelist Tools

The Data Storage needs of the Changelist Tools:

• Changelist Init
  • Find & Update Existing Storage File
  • Create New Changelists File
• ChangeList Sort
  • Find, Load & Update Existing Storage File
• ChangeList FOCI
  • Find & Read Existing Storage File

Package Structure

Call the public methods of the appropriate package for the level of detail required.

• changelist_data/ contains shared data classes.
• changelist_data/storage/ contains storage methods for read and write access.
• changelist_data/xml/ contains some xml tree abstractions and modules.
• changelist_data/xml/changelists/ changelists data xml management.
• changelist_data/xml/workspace/ workspace xml management.

Changelist Data

The highest level package does not import anything during initialization, or provide package level methods. It contains the common data classes shared by Changelist packages.

Common Data Classes:

class FileChange : Individual Files

• before_path: str | None = None
• before_dir: bool | None = None
• after_path: str | None = None
• after_dir: bool | None = None

Constructor Methods

• create_fc: represents created file.
• update_fc: a modified or moved file.
• delete_fc: a deleted file.

class Changelist : Lists of Files

• id: str
• name: str
• changes: list[FileChange] = field(default_factory=lambda: [])
• comment: str = ""
• is_default: bool = False

Module Methods

• get_default_cl: Get the default or first changelist in a list, tuple, or Iterable.
• compute_key: Compute a changelist key, derived from the changelist name.

Storage Package

This package contains modules for both workspace and changelist storage options. The storage option is passed in as an enum. Sensible default values are included.

• read_storage(StorageType, Path) -> list[Changelist]
• load_storage(StorageType, Path) -> ChangelistsDataStorage

Storage File Management:

• Find Existing Storage File and Read or Load it (Default is Changelists data xml)
• Search for Storage File via Argument (workspace file argument backwards compatibility)
• Create Changelists Data File if not exists

Read-Only Changelist Requirements:

• Find and Read the Workspace File into a List of Changelist data objects
• Find and Read the Changelists Data File into a List of Changelist data objects

Loading Changelist Data Tree Structures:

• Existing File is Loaded into one of the two Tree classes
• Tree classes handle updates to the storage data file

File Validation Module

This module determines if a storage option is already in use (one of those files exists).

• Check if .idea/workspace.xml exists
• Check if .changelists/data.xml exists
• Check given workspace_xml or data_xml file argument exists
• Validate the Input File, prevent loading any file over 32MB

XML Changelists Package

This package provides all the methods one may need for processing Changelists XML.

• read_xml(changelists_xml: str) -> list[Changelist]
• load_tree(changelists_xml: str) -> ChangelistsTree
• new_tree() -> ChangelistsTree

The new_tree method is a shortcut for creating a Changelists XML Tree. This is to be used when initializing changelist workflows for the first time in a project.

XML Workspace Package

This package provides methods for processing Workspace XML.

• read_xml(workspace_xml: str) -> list[Changelist]
• load_tree(workspace_xml: str) -> WorkspaceTree
