pdf — PDF files

Written by Scarlet for its sandbox. Available: pypdf (read, merge, split, rotate, metadata) and matplotlib (draws new pages). Not available: reportlab, LibreOffice, pandoc, Poppler, pip install, network.

How to make a file

Call run_code with skill="pdf". The helper make_pdf.py sits next to your code:

import matplotlib.pyplot as plt
from make_pdf import text_pdf

fig = plt.figure(figsize=(8.27, 11.69))
plt.bar(["T1", "T2", "T3"], [4, 7, 5])
plt.title("Số đơn hàng")

text_pdf("bao-cao.pdf", "Báo cáo tháng 10", [
    "Đoạn thứ nhất, viết thành câu đầy đủ. Dòng dài tự xuống hàng, hết trang tự sang trang.",
    "Đoạn thứ hai.",
], figures=[fig])
print("ok")

• text_pdf(path, title, paragraphs, figures=()): A4, title in bold, plain paragraphs (no bold/italic/tables inside the text), then one page per matplotlib figure. Text is real text (searchable, copyable).
• A table: draw it on a figure with plt.table(...) (turn the axes off) and pass the figure in figures.
• merge_pdfs(path, inputs): join PDFs you wrote earlier in the same run. Name the parts with a leading dot (.part1.pdf) so only the result is sent.
• Other page work with pypdf: PdfReader("x.pdf"), PdfWriter(), page.rotate(90), writer.add_metadata({...}), writer.write(...).

If the user needs a richly formatted document (styles, tables in text), suggest the docx skill instead — Word can save it as PDF.

Rules

• Save with a relative file name (current folder). Every file left there is sent to the user as a download — write exactly one .pdf.
• The user's uploaded files are not in the sandbox — you cannot open a PDF the user attached; build from the conversation text.
• A traceback in stderr means fix the code and call run_code again.
• After success, tell the user the file is ready to download in the panel.
