Error 'output: unbound variable' while executing 'doctoc.sh'

[jlegido]

First of all many thanks to all the people involved on this project for their time, I really appreciate it.

Steps to reproduce

1. Clone the git project

git clone https://github.com/dedis/cothority

2. Execute doctoc.sh:

bash cothority/doctoc.sh cothority/README.md 

Expected behaviour

Get an output similar to:

  Created doctoc.sh block in cothority/README.md succesfully

Found behaviour

The output is:

cothority/doctoc.sh: line 96: output: unbound variable

Error message

cothority/doctoc.sh: line 96: output: unbound variable

Workaround

If we comment out the set -u line:

sed -i 's/set -u/#set -u/g' cothority/doctoc.sh 

The script works.

thanks for catching that. I think a better fix would be to add a

output=""

before the while loop on line 86 of the doctoc.sh script. Can you test that and create a PR, please?

Done, thanks.
