DirectoryListing

Result of listing a directory, including the items and metadata about the listing operation.

DirectoryListing

def DirectoryListing(
    path:str, items:List, parent_path:Optional=None, provider_name:str='local', total_items:int=0,
    error:Optional=None
)->None:

Result of listing a directory.

from cjm_file_discovery.core.models import FileType

# Test DirectoryListing
listing = DirectoryListing(
    path="/home/user",
    items=[
        FileInfo(name="file.txt", path="/home/user/file.txt", is_directory=False),
        FileInfo(name="folder", path="/home/user/folder", is_directory=True),
    ],
    parent_path="/home"
)

assert listing.path == "/home/user"
assert len(listing.items) == 2
assert listing.total_items == 2
assert listing.parent_path == "/home"
assert listing.error is None

# Test with error
error_listing = DirectoryListing(
    path="/restricted",
    items=[],
    error="Permission denied"
)
assert error_listing.error == "Permission denied"

print("DirectoryListing tests passed!")

DirectoryListing tests passed!

BrowserSelection

Tracks the current selection state in the browser, supporting single and multiple selection modes.

---

source

BrowserSelection

def BrowserSelection(
    selected_paths:List=<factory>, last_selected:Optional=None
)->None:

Current selection state.

# Test BrowserSelection
selection = BrowserSelection()

# Test add
selection.add("/path/to/file1.txt")
assert selection.is_selected("/path/to/file1.txt")
assert selection.last_selected == "/path/to/file1.txt"

selection.add("/path/to/file2.txt")
assert len(selection.selected_paths) == 2
assert selection.last_selected == "/path/to/file2.txt"

# Test duplicate add (should not add twice)
selection.add("/path/to/file1.txt")
assert len(selection.selected_paths) == 2

# Test remove
selection.remove("/path/to/file1.txt")
assert not selection.is_selected("/path/to/file1.txt")
assert len(selection.selected_paths) == 1

# Test toggle
selection.toggle("/path/to/file2.txt")  # Remove
assert not selection.is_selected("/path/to/file2.txt")
selection.toggle("/path/to/file2.txt")  # Add back
assert selection.is_selected("/path/to/file2.txt")

# Test clear
selection.add("/path/to/file3.txt")
selection.clear()
assert len(selection.selected_paths) == 0
assert selection.last_selected is None

# Test set_single
selection.add("/path/to/file1.txt")
selection.add("/path/to/file2.txt")
selection.set_single("/path/to/only.txt")
assert len(selection.selected_paths) == 1
assert selection.is_selected("/path/to/only.txt")

print("BrowserSelection tests passed!")

BrowserSelection tests passed!

BrowserState

Complete browser state for persistence and restoration. This captures everything needed to restore the browser to a specific state.

---

source

BrowserState

def BrowserState(
    current_path:str, selection:BrowserSelection=<factory>, sort_by:str='name', sort_descending:bool=False,
    filter_extensions:Optional=None
)->None:

Complete browser state for persistence/restore.

# Test BrowserState
state = BrowserState(
    current_path="/home/user",
    sort_by="modified",
    sort_descending=True,
    filter_extensions=[".py", ".txt"]
)

state.selection.add("/home/user/file.txt")

assert state.current_path == "/home/user"
assert state.sort_by == "modified"
assert state.sort_descending == True
assert state.filter_extensions == [".py", ".txt"]
assert state.selection.is_selected("/home/user/file.txt")

# Test serialization round-trip
state_dict = state.to_dict()
restored_state = BrowserState.from_dict(state_dict)

assert restored_state.current_path == state.current_path
assert restored_state.sort_by == state.sort_by
assert restored_state.sort_descending == state.sort_descending
assert restored_state.filter_extensions == state.filter_extensions
assert restored_state.selection.selected_paths == state.selection.selected_paths

# Test defaults
default_state = BrowserState(current_path="/")
assert default_state.sort_by == "name"
assert default_state.sort_descending == False
assert default_state.filter_extensions is None

print("BrowserState tests passed!")
