Xkcd ¶
Xkcd(bot: Tux)
Bases: BaseCog
Discord cog for xkcd comic viewing commands.
Provides commands to fetch and display xkcd comics from the xkcd webcomic. Supports viewing the latest comic, random comics, and specific comics by ID. Comics are displayed with navigation buttons to the explanation and original pages.
Initialize the Xkcd cog.
Parameters:
-
bot(Tux) –The bot instance to attach this cog to.
Methods:
-
xkcd–Xkcd related commands.
-
latest–Get the latest xkcd comic.
-
random–Get a random xkcd comic.
-
specific–Get a specific xkcd comic.
-
get_comic_and_embed–Get the xkcd comic and create an embed.
-
get_config–Get a configuration value from CONFIG with support for nested keys.
-
__repr__–Return a string representation of the cog instance.
-
unload_if_missing_config–Check if required configuration is missing and log warning.
Attributes:
-
db(DatabaseCoordinator) –Get the database coordinator for accessing database controllers.
Attributes¶
db property ¶
db: DatabaseCoordinator
Get the database coordinator for accessing database controllers.
Returns:
-
DatabaseCoordinator–Coordinator providing access to all database controllers.
Examples:
>>> 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¶
xkcd async ¶
latest async ¶
_setup_command_usage ¶
_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.
random async ¶
specific async ¶
_generate_usage ¶
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.
get_comic_and_embed async ¶
get_config ¶
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:
>>> 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__ ¶
__repr__() -> str
Return a string representation of the cog instance.
Returns:
-
str–String representation in format
<CogName bot=BotUser>.
unload_if_missing_config ¶
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:
>>> 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 ¶
_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.
