Weave is a scientific report generator/literate programming tool for the Julia programming language. It resembles Pweave, knitr, R Markdown, and Sweave.

You can write your documentation and code in input document using Markdown, Noweb or ordinal Julia script syntax, and then use

function to execute code and generate an output document while capturing results and figures.

Current features

  • Publish markdown directly to HTML and PDF using Julia or Pandoc
  • Execute code as in terminal or in a unit of code chunk
  • Capture Plots.jl or Gadfly.jl figures
  • Supports various input format: Markdown, Noweb, Jupyter Notebook, and ordinal Julia script
  • Conversions between those input formats
  • Supports various output document formats: HTML, PDF, GitHub markdown, Jupyter Notebook, MultiMarkdown, Asciidoc and reStructuredText
  • Simple caching of results

Weave in Juno demo


You can install the latest release using Julia package manager:

using Pkg


using Weave

add depencies for the example

using Pkg; Pkg.add(["Plots", "DSP"])

filename = normpath(Weave.EXAMPLE_FOLDER, "FIR_design.jmd") weave(filename, out_path = :pwd)

If you have LaTeX installed you can also weave directly to pdf.

filename = normpath(Weave.EXAMPLE_FOLDER, "FIR_design.jmd")
weave(filename, out_path = :pwd, doctype = "md2pdf")


just points to


Documenter.jl with MKDocs generated documentation:

Editor support

Install language-weave to add Weave support to Juno. It allows running code from Weave documents with usual keybindings and allows preview of html and pdf output.

The Julia extension for Visual Studio Code adds Weave support to Visual Studio Code.


You can contribute to this package by opening issues on GitHub or implementing things yourself and making a pull request. We'd also appreciate more example documents written using Weave.
