Convert a SnakeViz HTML file into a self-contained static file that can be hosted anywhere. This script replaces instances of static files being loaded from the local server by having them come from the rawgit CDN.
#!/usr/bin/env python
"""
Prepare an HTML file from SnakeViz for use as a static page.
This makes it so all static files are loaded from a CDN instead
of from the local server.
To get the SnakeViz HTML file run the snakeviz CLI to load a profile
in your browser, than save that page as an HTML file to your computer.
Finally, run this script on that HTML file.
This script prints the modified HTML to stdout.

Instructions for using this:

  • Open a profile in SnakeViz using the snakeviz CLI
  • Save the page as an HTML file (if given the option say save as HTML only)
  • Run this script on that file
    • The output is sent to stdout so you may want to redirect it to another file, e.g. svstatic myfile.html > myfile_static.html
    • On my Mac I use the pbcopy utility to copy the HTML to my clipboard: svstatic myfile | pbcopy

A gist is a great place to host your file. Copy the HTML produced by running svstatic into a gist and give the gist a filename ending in .html. Click the "Raw" button to get the URL of the raw HTML, then paste that URL into https://rawgit.com/. Share the link RawGit gives you!

As an example, I turned this HTML gist:

into this page:

using RawGit.

Hi, it's great, but why don't you provide the feature in snakeviz? I don't want to have to save the page as html.
SnakeViz could offer the feature of just outputting the html file / outputting the html file with the static directory.
