Convert Stylus to SASS/SCSS

Convert Stylus to SASS

Here's how I converted a whole batch of Stylus files to SASS without using a converter (none exist, that I'm aware of), converting each Stylus file manually, or programming my own Stylus->SASS converter, which would have entailed building a parser, and then generate SCSS from the AST.

First, grab sandr.py here: https://github.com/jfgiraud/sandr

Then, in the directory of your Stylus files, run (if you have multiple directory levels, you can do similar task using find):

for file in *.styl; do echo "/*! FILENAME: $file */" >tempfile; cat $file >>tempfile; mv tempfile $file; done

easy d3 zoom and pan

I know a lot of people have trouble zooming and panning d3. Indeed, I found myself in a situation where I had a simple bar chart to which I wanted to add the zoom behavior, and also make the full chart draggable. I saw several extremely complex examples of d3 charts with zooming and panning, and thought that there must be an easier way, particularly if you don't need to scale the x and y axes. There is, and here is is in CoffeeScript:

vis.call(d3.behavior.zoom()
  .on("zoom", ->
    g.attr("transform", "translate(" + d3.event.translate[0] + "," + d3.event.translate[1] + ") scale(" + d3.event.scale + ")")
  )
)
