Documenting Code and Pictures

For the SVGo workshop I had to document many examples of code+pictures, so I created a workflow to create consistently formatted illustrations of SVGo code and the pictures they produce. Below is the script that automates the process. The heart of the script is a small Go program, codepic which creates a SVG file of code and picture:
Here's the script:
#!/bin/sh
for i in $*
do
    base=`basename $i .go`
    gofmt -w -spaces -tabindent=false -tabwidth=4 $i &&
    goc $base && 
    ./${base} > ${base}.svg && 
    codepic -codeframe=f -font Inconsolata -fs 14 -ls 16 $i > ${base}-slide.svg && 
    svg2pdf ${base}-slide.svg
done
for each file the script:
  1. formats the source
  2. builds the source
  3. runs the program and captures its output
  4. make a slide showing the code and output
  5. convert the slide to PDF for inclusion in Keynote
