In plain English

JMComic-Crawler-Python is a Python library and command-line tool for downloading content from a specific adult comics website. The README is written primarily in Chinese. The project wraps the website's API into a Python interface so that users can download entire comic albums with a few lines of code or a single terminal command. The basic usage requires knowing the numeric ID of a comic on the site. A user can then either run a command like jmcomic 123 in the terminal, call the Python function jmcomic.download_album('123') in a script, or trigger a download directly through GitHub Actions by entering the ID into a web form, with no local Python installation needed for that last option. The library supports a configuration file where users can set options such as which image format to save files in, how many threads to use for parallel downloading, whether to use a proxy, and which client mode to use. There are two client modes: one that mimics the website's mobile app (works from more locations) and one that mimics the web browser (faster but restricted by region). The tool handles the site's anti-bot measures and implements the encryption and decryption used by the mobile app's API. A plugin system lets users extend the tool's behavior. Built-in plugins cover things like converting downloaded images to PDF or a single tall image, sending an email notification when a download completes, skipping chapters already downloaded, compressing output into a zip file, and logging hardware usage during a run. Users can also write their own plugins. The project requires Python 3.9 or later, with Python 3.12 or newer recommended. It is installable from PyPI with pip install jmcomic and has fuller documentation hosted on ReadTheDocs.

Copy-paste prompts

Prompt 1
I have the jmcomic Python library installed. Write a Python script that reads a list of comic IDs from a text file and downloads each one using jmcomic.download_album(), skipping any that have already been downloaded.
Prompt 2
Using the jmcomic library, write a config file that sets parallel threads to 8, enables a proxy at 127.0.0.1:7890, saves images as jpg, and activates the PDF conversion plugin after each download.
Prompt 3
Show me how to write a custom jmcomic plugin that sends a Slack webhook notification when a download finishes, following the project's plugin interface conventions.
