deck — master-template renderer
Generate a brand-perfect .pptx by composing plans against a brand pack's master.pptx. The master supplies typography, colors, footers, slide-number chrome — the renderer only fills placeholders and clones bespoke shapes.
Quick Start
from pathlib import Path
from feinschliff import FillPlan, render
render(
Path("feinschliff/brands/feinschliff"),
[FillPlan(layout="Title Slide", fills={0: "Q3 update", 1: "Roadmap"})],
Path("out.pptx"),
)
Author the call in feinschliff/.debug/<topic>-<date>/build.py and run it with feinschliff build.py — the plugin's launcher execs the venv Python directly, no CLI in between.
Brand packs
Each pack ships under feinschliff/brands/<name>/ with a master.pptx (or .ref pointer) and catalog files. Built-in packs: feinschliff (default), annual-review, geometric, scientific, shapes, gs-ramspau. Corporate / private packs surface through sibling feinschliff-* plugin directories ($FEINSCHLIFF_BRAND_PATH). Run python -m feinschliff.master_template.catalog <brand_pack> to list layouts + snippets for any pack.
Mental model
A deck is a list of plans, in slide order:
FillPlan(layout, fills) — pick a layout by name (see <brand>/layouts.yaml), fill placeholders by idx. Values: str, list[str], PictureRef, or ChartSpec. Charts and pictures replace the OBJECT placeholder.ClonePlan(source_idx, replacements) — XML-clone a bespoke source slide from <brand>/snippets.yaml. replacements is a queue per old-string; repeating ("Milestone", ...) consumes successive occurrences in document order.render(..., theme=Path|dict) — optional. Patches the master's theme1.xml <a:clrScheme> from a small JSON. One master.pptx, N visual variations; the file on disk is never touched.
Flow
- Interview if the brief is thin. Topic + audience are the minimum; references/storyline.md maps audience to a default slide count.
- Draft the storyline per references/storyline.md — emit the brief block + numbered slides block, pick a frame, tag each row with
role and act, write claim-style titles.
- Pick layouts per references/layouts.md. For bespoke shapes (timelines, funnels, infographics) clone from
<brand>/snippets.yaml — see references/clones.md for the text-anchor recipe.
- Approval gate — show storyline + chosen layouts, ask "ok?". Don't render until approved.
- Render with the Quick Start snippet. Respect the verbosity tier when sizing fills. See references/gotchas.md for pitfalls.
- Verify and loop — convert to PDF and read the pages against the defect classes in references/verify.md. Fix and re-render until clean; the reference describes the
/loop-driven iteration.
