Octavo

The quantitative social science starter pack

日本語の README

Write your papers, slides and lecture notes in Markdown, keep the analysis in Quarto, and let Octavo put the analysis's numbers, figures and tables into every document — then typeset them to PDF (with Typst) and Word, or LaTeX if you have TeX. Citations come from one .bib file, in any CSL style.

What you get

A page of a paper and a slide, both built from the example project (octavo init demo --all --example). The coefficient, the table and the figure come from the analysis; the equation, table and figure numbers and the references are filled in when it is typeset.

• No number is typed by hand. The analysis registers it (ov_value("n_obs", nrow(d))) and the manuscript calls it by name ({{n_obs}}). Re-run the analysis and every document follows. octavo check points out numbers typed into the prose, and values that are only placeholders.
• One source, several documents. A paper in your journal's layout, a talk, and lecture notes that become an A4 handout plus one slide deck per session — with speaker scripts, and Word for coauthors.
• References by label: @fig-trend becomes "Figure 2.1", and stays right when you reorder sections.
• Up to submission and after: word limits, blind review, a submission zip, reading a coauthor's tracked changes in Word, "what moved since I submitted", and a replication package.
• A VS Code extension with a live PDF preview, a sidebar for everything above, and one-click setup.
• Linux, macOS and Windows; English and Japanese.

Install

With VS Code, install the Octavo extension and press Set up when it asks: it installs pandoc, Typst, Quarto, R, the fonts and the octavo command.

From a terminal:

curl -LsSf https://astral.sh/uv/install.sh | sh   # uv, if you don't have it yet
uv tool install octavo-kit                        # the octavo command
octavo setup                                      # pandoc / Typst / Quarto / fonts / R
octavo doctor                                     # reports anything still missing

Getting started

See it work first — an example with an analysis, a paper, slides and lecture notes:

octavo init demo --all --example
cd demo
octavo build --compile        # runs the analysis, then typesets everything to PDF

Then your own project, starting with the parts you need:

octavo init study --with analysis,paper
cd study
octavo env                    # the project's analysis environment (.venv and renv)
octavo build paper --compile  # after writing analysis/analysis.qmd and papers/paper/paper.md
octavo check                  # before you submit

In the analysis, register what the paper shows; in the manuscript, refer to it:

ov_value("n_obs", nrow(d))
ov_figure(p, "trend")

The sample has {{n_obs}} cases (@fig-trend).

![Trend](../../figures/trend.png){#fig-trend}
