asciinema
=========
The animated Gifs you find in the DTail docs were created using:
* [asciinema](https://asciinema.org)
* [asciicast2gif](https://github.com/asciinema/asciicast2gif)
On Fedora Linux 35.
## Installing prerequisites
On Fedora Linux 35 install `asciinema`:
```shell
% sudo dnf install -y asciinema
```
and `asciicast2gif` (for simplicity, the Docker image was used):
```shell
% docker pull asciinema/asciicast2gif
```
This of course assumes that Docker is up and running on your machine (out of scope for this documentation).
## Record a shell session
This is as simple as running
```shell
% asciinema rec recording.json
```
This will launch a sub-shell to be recorded. Once done, exit the sub-shell with `exit`.
## Convert the recording to a gif
```shell
% docker run --rm -v $PWD:/data asciinema/asciicast2gif -t tango -s 2 recording.json recording.gif
```
