Weave.jl review
A focused Julia tool for executing code in reports and exporting to multiple document formats.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Weave.jl is an open-source Julia package for reproducible scientific reports and literate programming. It is aimed at Julia authors who want to combine explanatory prose with executable code, then publish the resulting work in formats suited to readers, collaboration, or further editing. Inputs include Markdown, Noweb, Jupyter Notebook, and Julia scripts, so it can accommodate several authoring styles rather than requiring one document format.
Its main strength is carrying Julia execution through to the finished document. Code can run in terminal-style or code-chunk workflows, with results and figures captured in the output; plotting support includes Plots.jl and Gadfly.jl. Simple result caching can avoid repeating work, while conversion between supported input formats and outputs including HTML, PDF, GitHub Markdown, Jupyter Notebook, MultiMarkdown, Asciidoc, and reStructuredText gives reports several publishing paths. Juno and Visual Studio Code integration also connects it with familiar Julia editing environments. This makes Weave.jl a fit when computational content is central to the report, rather than an incidental code snippet.
Weave.jl is self-hosted and open source, with community and documentation support. Its Julia focus is also the main boundary: teams seeking a language-neutral documentation system or a managed publishing service should consider alternatives. The published repository lists v0.10.12 as the latest release, dated February 2023, a relevant signal for buyers assessing maintenance needs. Julia researchers and developers who value executable reports, plotting, caching, and format choice may find that tradeoff appropriate; organizations needing current release activity or broader language coverage should assess other options.
Weave.jl pros and cons
- Where it wins
- Executes Julia code alongside prose in several supported input formats
- Exports to HTML, PDF, notebooks, and multiple text formats
- Captures Plots.jl and Gadfly.jl figures and offers simple result caching
- Where it doesn't
- Focused on Julia rather than general-purpose documentation generation
- Self-hosted deployment requires users to manage their own environment
- Support is through community resources and documentation
