# scripted demo for https://asciinema.org/
|
|
# to use:
|
|
# 1. create virtualenv with autobahn, ansicolors and asciinema installed:
|
|
# pip install autobahn asciinema ansicolors
|
|
# 2. change to root of fresh AutobahnPython checkout
|
|
# 3. a) to record and upload, run:
|
|
#
|
|
# asciinema -c ./examples/asciinema-autobahn-demo.py rec
|
|
#
|
|
# 3. b) to just test this (e.g. without recording anything):
|
|
#
|
|
# python asciinema-autobahn-demo0.py
