# This script is used to generate the images for the examples README
# It requires the following tools:
# - cargo: https://doc.rust-lang.org/cargo/getting-started/installation.html
# - gh: https://github.com/cli/cli
# - git: https://git-scm.com/
# - vhs: https://github.com/charmbracelet/vhs - currently this needs to be installed from the
# main branch, as the latest release doesn't support the theme we use or the Screenshot
# command. Install using `go install github.com/charmbracelet/vhs@main``
# - go: https://golang.org/doc/install
# - ttyd: https://github.com/tsl0922/ttyd
# Exit on error. Append "|| true" if you expect an error.
set -o errexit
# Exit on error inside any functions or subshells.
set -o errtrace
# Do not allow use of undefined vars. Use ${VAR:-} to use an undefined VAR
set -o nounset
# Catch the error in case mysqldump fails (but gzip succeeds) in `mysqldump |gzip`
set -o pipefail
# Turn on traces, useful while debugging but commented out by default
# set -o xtrace
# ensure that running each example doesn't have to wait for the build
