Below is my current travel spoke repair kit, including a good spoke wrench. I picked the design for on-the-go spoke repair on a German list.

My getting home, unexpected repair and recovery sequence runs a bit differently. I was riding a rented bike in Sicily and got hit by a current suddenly moving out of a parking slot. My hand was bruised, but the bike looked OK. Only after I started riding did the wheel get more and more out of shape to nearly locking. I managed to get to my base, but there was no way I could get to the other side of town to my rental. I took out the spoke wrench from my travel tool kit and started straightening the wheel. I got it to a shape where normal riding was possible, but the wheel was still in a shape you would not want. With the spoke wrench I had at the time, I also ruined the nipples - being shaken after the accident presumably also played a role. The next day, I took the bike to the rental, and they replaced the wheel. When I was returning the bike for good, they charged me only 25 euros for the straightening of the wheel, including new nipples. That rental was a counterbalance to the accident that also came with a rude, repugnant driver. Afterward, I upgraded my spoke wrench.
