simwrapper 1.3.1

Python support library for SimWrapper data visualization tool

SimWrapper Python Tools

Official python library for working with SimWrapper.

SimWrapper is a data visualization tool for exploring large transport simulation results.

About this library

This library contains the "simwrapper" command-line tool, which allows browsing of local files on your PC/laptop using the SimWrapper website.

We are at the very early stages of building this tool. The API will change, things will break, and there are certainly bugs.

• Our primary goal is to make it easy to get local simulation results viewable using the SimWrapper website.
• We have only tested this using Anaconda Python. Only Python 3.x is supported.

Installation

Install once, using pip install simwrapper

Usage

simwrapper knows two commands:

• simwrapper serve starts a local file server in the current directory. Run this command, then browse to either https://vsp.berlin/simwrapper or https://activitysim.github.io/dashboard to view your local folder outputs.

• simwrapper open [vsp|asim] opens a new web browser tab AND a local file server in the current directory. The site will only operate as long as you keep that local server running, so don't close the command window.

  • For the ActivitySim site, use simwrapper open asim
  • For the VSP MATSim site, use simwrapper open vsp

Running as HTTPS - required for Safari

Safari blocks HTTPS websites (such as SimWrapper VSP and ASIM) which access localhost resources such as this local simwrapper file server. You can run simwrapper in HTTPS mode by following these extra instructions.

Both simwrapper commands accept --key and --cert options to specific the two pieces of a PEM certicate. You can create a PEM certificate for "localhost" and install it in your browser's certificate database with the following commands.

This requires Homebrew, which supplies the brew command.

brew install mkcert nss   # installs mkcert command
mkcert localhost          # Create PEM key/cert files for "localhost"
mkcert -install           # Installs certificates in browser

This creates two files: localhost.pem and localhost-key.pem. Move them somewhere where you cn find them.

Now you can run simwrapper as follows:

• simwrapper serve --cert localhost.pem --key localhost-key.pem
• simwrapper open asim --cert localhost.pem --key localhost-key.pem

That's it!
