mangalib

mangalib-python-sdk (import mangalib): titles, chapters, translations, the catalog and chapter pages of mangalib.me, with export to CBZ or PDF.

Installation

uv add mangalib-python-sdk          # or: pip install mangalib-python-sdk
uv add "mangalib-python-sdk[pdf]"   # with PDF export (img2pdf)

Without the pdf extra, "pdf" just isn't one of the export formats (EXPORTERS).

Quickstart

from mangalib import Catalog, MangaLib

async with MangaLib("https://mangalib.me/ru/manga/7965--chainsaw-man") as lib:
    info = await lib.get_info()
    toc = await lib.get_table_of_contents()

    # Chapter 1 has two translations: pick one.
    translations = await lib.get_translations(volume=1, number="1")
    chapter = await lib.get_chapter(volume=1, number="1", branch_id=translations[0].branch_id)

    images = await lib.download_pages(chapter)  # list[bytes], in reading order
    await lib.export([chapter], fmt="cbz", path="chainsaw-man-1.cbz")

    size = await lib.estimate_title_size()  # bytes of page images, from a sample
    volumes = await lib.download_title(translation_index=0, on_chapter=print)
    await lib.export(volumes, fmt="pdf", path="chainsaw-man.pdf", on_chapter=print)

async with Catalog() as catalog:
    page = await catalog.list_titles(query="chainsaw")

Chapters are pages

A fetched chapter has pages instead of text: each Page is a position, a size and a path on an image server. The servers come from list_image_servers(), and not all of them let a script in. download_page() starts from compress and falls back to the next one. It paces its requests per image host across the process and retries a 429/5xx before moving on.

chapter_size() and volume_size() give the exact size of the images from HEAD requests, without downloading them. estimate_title_size() extrapolates from a sample of chapters.

Paid and early-access chapters

There's no login. ChapterBranch.is_open says whether a translation can be read without an account. Fetching a closed chapter raises AuthRequiredError. A whole-title download or estimate leaves closed chapters out.
