This is a quick script to produce the available versions of Python in a JSON format.
Usage of ./py-versions:
-o string
Filename to save JSON output (optional; if not provided, output to console)
-url string
Python FTP Mirror URL (default "https://www.python.org/ftp/python/")
This can be combined with other scripts to alert when a new version is available. This is especially useful when working with embedded and compiled executables.
#!/bin/bash
# Define constants
ALERT_URL="https://api.example.com/v1/project-key"
TOKEN="tk_AgQdq7mVBoFD37zQVN29RhuMzNIz2"
# Log function
log() {
echo "$(date +"%Y-%m-%d %T") $1"
}
# Get the target version from the user input, defaulting to 3.9.19 if no input is provided
if [ -z "$1" ]; then
target_version="3.9.19"
else
target_version="$1"
fi
# Extract the minor version from the target version
target_minor_version=$(echo "$target_version" | cut -d. -f1,2)
# Get the latest version of Python
version=$(./py-versions | grep -oP "(?<= \"$target_minor_version\":\{\"latest\":\")[^\"]+")
if [[ -z "$version" ]]; then
log "Error: Failed to retrieve the latest version of Python."
exit 1
fi
# Check if the latest version has a different minor version
if [[ "$version" =~ ^$target_minor_version\. ]]; then
# Prepare alert message
alert_message="There is a new version of Python $target_minor_version available: $version"
# Send an alert with the version number using curl
response=$(curl -s -H "Authorization: Bearer $TOKEN" -d "$alert_message" "$ALERT_URL")
# Check if alert was successfully sent
if [[ "$response" != "success" ]]; then
log "Error: Failed to send alert. Response: $response"
exit 1
fi
log "Alert sent successfully: $alert_message"
else
log "No new version of Python $target_minor_version available."
fiThe above could then be combined with cron jobs to alert when a new version is available through:
0 8 * * * /path/to/example-script.sh 3.9.19The 3.9.19 argument is optional and defaults to 3.9.19 if not provided. The API endpoint may trigger an action, such as sending a Slack message or initating a new build with CI/CD pipelines.
