rosenv

Bash addon script to change ROS environments quickly and persistent across shells

---

How to use:

1. Source script rosenv.sh in your .bashrc or else: source PATH/TO/rosenv.sh
2. Source after you sourced ROS to avoid <unknown> printout.
3. Open new shell/terminal.
4. Setup will run, greeting shows.
5. Usage: rosenv ENV_NAME

• To change default csv file dir: export ROSENV_DIR=/some/path (default: same location as rosenv.sh)
• To use a different subnet ip: export ROSENV_SUBNET=10.0 (default: 192.)

Usage example

Usage: rosenv ENV_NAME
Try 'rosenv local' for the local environment.

Currently available ROS environments:
-------------------------------------
local,127.0.0.1,http://127.0.0.1:11311
-------------------------------------

Add more environments in '/home/vater/rosenv/rosenv.csv', one per line, in the form:

  env name,ROS_IP/ROS_HOSTNAME,ROS_MASTER_URI[,comment]

You can use function 'getIP' to get the first local subnet ip (192. ..), if any
or 'getIP INTERFACE_NAME' to get that interface-specific ip.
Hint: Use the hostname of the ROS_MASTER_URI machine for greater flexibility.

Exemplary 'rosenv.csv' content:

  local,127.0.0.1,http://127.0.0.1:11311
  turtle,$(getIP),http://super-mega-bot.local:11311,connected to subnet
  skynet,$(getIP wlp2s0),http://666.0.815.007:88888,via wifi
  hal,dave-pc,http://2.0.0.1:9000

Hacks

Add a line like ,127.0.0.1,http://127.0.0.1:11311 (notice no env name!) and just type rosenv (without arg) for switching to this one.

Tested on

Ubuntu 16.04.5 LTS
GNU bash, version 4.3.48(1)-release (x86_64-pc-linux-gnu)
