Weave

Weave is a scientific report generator/literate programming tool for Julia. It resembles Pweave and, Knitr and Sweave.

Current features

• Noweb or markdown syntax for input documents.
• Execute code as terminal or "script" chunks.
• Capture PyPlot, Gadfly or Winston figures.
• Supports LaTex, Pandoc and Github markdown and reStructuredText output

Chunk options

I've tried to follow Knitr's naming for chunk options, but not all options are implemented. You can see src/config.jl for the current situation.

Options are separated using ";" and need to be valid Julia expressions. e.g.

<<term=true; fig_width=6; fig_height=4>>=

File formats

You can get a list of supported output formats:

julia> list_out_formats()
pandoc: Pandoc markdown
rst: reStructuredText and Sphinx
texminted: Latex using minted for highlighting
github: Github markdown
tex: Latex with custom code environments

Usage

Run from julia:

using Weave
weave(Pkg.dir("Weave","examples","julia_sample.mdw")

Using Winston for plots (Julia 0.3 only):

weave(Pkg.dir("Weave","examples","winston_sample.mdw"),
plotlib="Winston", doctype="pandoc")

Using Gadfly (Julia 0.3 only):

weave(Pkg.dir("Weave","examples","gadfly_sample.mdw"), plotlib="Gadfly")

The signature of weave functions is:

function weave(source ; doctype = "pandoc", plotlib="Gadfly", informat="noweb", out_path=:doc, fig_path = "figures", fig_ext = nothing)

• doctype: see list_out_formats()
• plotlib: "PyPlot", "Gadfly", or "Winston"
• informat: "noweb" of "markdown"
• out_path: Path where the output is generated:
  • :doc: Path of the source document.
  • :pwd: Julia working directory
  • "somepath": Path as a string e.g "/home/mpastell/weaveout"
• fig_path: where figures will be generated, relative to out_path
• fig_ext: Extension for saved figures e.g. ".pdf", ".png". Default setting depends on doctype.

Note: Run Weave from terminal and not using IJulia, Juno or ESS, they tend to mess with capturing output.

Contributing

I will probably add new features to Weave when I need them myself or if they are requested and not too difficult to implement. You can contribute by opening issues on Github or implementing things yourself and making a pull request. I'd also appreciate example documents written using Weave to add to examples.
