pptx — PowerPoint decks

Written by Scarlet for its sandbox. python-pptx, pillow and matplotlib are available — no LibreOffice, no Node, no pip install, no network.

How to make a file

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

import matplotlib
matplotlib.use("Agg")
import matplotlib.pyplot as plt
from make_pptx import build_pptx

plt.bar(["Q1", "Q2", "Q3"], [12, 18, 25])
plt.title("Doanh thu (tỷ đồng)")
plt.savefig(".revenue.png", dpi=150, bbox_inches="tight")

build_pptx("ke-hoach.pptx", [
    {"title": "Kế hoạch quý 4", "subtitle": "Phòng Kinh doanh"},
    {"title": "Mục tiêu", "bullets": ["Tăng doanh thu 20%", ["Kênh online", 1], "Giữ chân khách cũ"],
     "notes": "Nhấn mạnh kênh online."},
    {"title": "Doanh thu theo quý", "image": ".revenue.png"},
])
print("ok")

Slide dict:

Keys	Slide
title, subtitle	title slide (no bullets / image)
title, bullets	bullet slide; a bullet is "text" or ["text", level], level 0–4
title, image	picture fitted under the title (PNG/JPEG written in the same run)
notes (any slide)	speaker notes

Keep it to 3–6 bullets per slide, short phrases, one idea per slide. Slides are 4:3 with the plain default theme. For anything else (shapes, tables, colours) use python-pptx directly: Presentation(), prs.slides.add_slide(...), prs.save("name.pptx").

Rules

• Save with a relative file name (current folder). Every file left there is sent to the user as a download — write exactly one .pptx; chart images must start with a dot (.revenue.png) so they are not sent.
• The user's uploaded files are not in the sandbox — 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.
