Attributes:

Attributes

db property
Python
db: DatabaseCoordinator

Get the database coordinator for accessing database controllers.

Returns:

Examples:

Python Console Session
>>> await self.db.guild_config.get_guild_config(guild_id)
>>> await self.db.cases.create_case(...)
Notes

This property provides convenient access to database operations without needing to access self.bot.db directly.

Functions

create_embed
Python
create_embed(title: tuple[str, str], ctx: Context[Tux]) -> Embed

Create a Discord embed message based on the search result.

Parameters:

  • title (tuple[str, str]) –

    A tuple containing the title and description of the search result. If the first element is "error", it indicates no search results were found.

  • ctx (Context[Tux]) –

    The context object for the command.

Returns:

  • Embed –

    The created embed message.

query_wiki async
Python
query_wiki(base_url: str, search_term: str) -> tuple[str, str]

Query a wiki API for a search term and return the title and URL of the first search result.

Parameters:

  • base_url (str) –

    The base URL of the wiki API.

  • search_term (str) –

    The search term to query the wiki API with.

Returns:

  • tuple[str, str] –

    The title and URL of the first search result.

_setup_command_usage
Python
_setup_command_usage() -> None

Generate usage strings for all commands in this cog that lack explicit usage.

The generated usage follows the pattern: <qualified_name> <param tokens>

Where: - Required parameters are denoted as <name: Type> - Optional parameters are denoted as [name: Type] - The prefix is intentionally omitted (provided by ctx.prefix)

Examples:

ban <member: Member> [reason: str] config set <key: str> <value: str>

Notes

Respects explicit usage strings if already set on a command. Errors during generation are logged but don't prevent cog loading.

_generate_usage
Python
_generate_usage(command: Command[Any, ..., Any]) -> str

Generate a usage string with support for flags and positional parameters.

This method inspects the command's callback signature to detect: - FlagConverter parameters (e.g., --flag value) - Positional parameters (e.g., <required> or [optional])

Parameters:

  • command (Command) –

    The command to generate usage for.

Returns:

  • str –

    Generated usage string, or qualified command name as fallback.

Notes

Delegates to shared usage generator for consistency across all cogs. Falls back gracefully to command name if generation fails.

wiki async
Python
wiki(ctx: Context[Tux]) -> None

Wiki related commands.

Parameters:

  • ctx (Context[Tux]) –

    The context object for the command.

arch_wiki async
Python
arch_wiki(ctx: Context[Tux], query: str) -> None

Search the Arch Linux Wiki.

Parameters:

  • ctx (Context[Tux]) –

    The context object for the command.

  • query (str) –

    The search query.

atl_wiki async
Python
atl_wiki(ctx: Context[Tux], query: str) -> None

Search the All Things Linux Wiki.

Parameters:

  • ctx (Context[Tux]) –

    The context object for the command.

  • query (str) –

    The search query.

get_config
Python
get_config(key: str, default: Any = None) -> Any

Get a configuration value from CONFIG with support for nested keys.

Parameters:

  • key (str) –

    The configuration key to retrieve. Supports dot notation for nested values (e.g., "BOT_INFO.BOT_NAME").

  • default (Any, default: None ) –

    Default value to return if key is not found, by default None.

Returns:

  • Any –

    The configuration value or default if not found.

Examples:

Python Console Session
>>> self.get_config("BOT_INFO.BOT_NAME")
'Tux'
>>> self.get_config("MISSING_KEY", "fallback")
'fallback'
Notes

Errors during retrieval are logged but don't raise exceptions. Returns the default value on any error.

__repr__
Python
__repr__() -> str

Return a string representation of the cog instance.

Returns:

  • str –

    String representation in format <CogName bot=BotUser>.

unload_if_missing_config
Python
unload_if_missing_config(condition: bool, config_name: str) -> bool

Check if required configuration is missing and log warning.

This allows cogs to detect missing configuration at load time and return early from init to prevent partial initialization.

Parameters:

  • condition (bool) –

    True if config is missing (should unload), False otherwise.

  • config_name (str) –

    Name of the missing configuration for logging purposes.

Returns:

  • bool –

    True if config is missing (caller should return early), False if config is present.

Examples:

Python Console Session
>>> def __init__(self, bot: Tux):
...     super().__init__(bot)
...     if self.unload_if_missing_config(not CONFIG.GITHUB_TOKEN, "GITHUB_TOKEN"):
...         return  # Exit early, cog will be partially loaded but won't register commands
...     self.github_client = GitHubClient()
Notes

When this returns True, the cog's init should return early to avoid initializing services that depend on the missing config. The cog will be loaded but commands won't be registered properly, preventing runtime errors.

For complete cog unloading, the bot owner should remove the cog from the modules directory or use the reload system to unload it programmatically.

_unload_self async
Python
_unload_self(extension_name: str) -> None

Perform the actual cog unload operation.

Parameters:

  • extension_name (str) –

    Full extension name to unload.

Notes

This is called as a background task by unload_if_missing_config(). Errors during unload are logged but don't raise exceptions.

Functions

setup async

Python
setup(bot: Tux) -> None

Set up the Wiki cog.

Parameters:

  • bot (Tux) –

    The bot instance to add the cog to.
