# Aider chat conversation:
USER: the console log format should change the log message color based on the level of the message. all console log messages should start with the date and time in iso format with millisecond resolution
ASSISTANT: To change the console log format to include the date and time in ISO format with millisecond resolution and to change the log message color based on the level of the message, we need to:
1. Update the `Handle` method in `console_handler.go` to format the log message accordingly.
2. Use different colors for different log levels.
Here are the changes:
console_handler.go
```go

func NewConsoleHandler() *ConsoleHandler {

color.New(color.FgBlue).PrintfFunc()("%s: %s\n", record.Level, record.Message)
return nil

Did you mean to match some of these actual lines from console_handler.go?

simplelog
simplelog is an opinionated logging package designed to facilitate easy and structured logging in Go applications with an absolute minimum of boilerplate.
The idea is that you can add a single import line which replaces the
stdlib log/slog default handler, and solve the 90% case for logging.
Features
- if output is a tty, outputs pretty color logs
- if output is not a tty, outputs json
- supports delivering logs via tcp RELP (e.g. to remote rsyslog using imrelp)
- supports delivering each log message via a webhook
Installation
To use simplelog, first ensure your project is set up with Go modules:
go mod init your_project_name
Then, add SimpleLog to your project:
go get git.eeqj.de/sneak/go-simplelog
Usage
Below is an example of how to use SimpleLog in a Go application. This example is provided in the form of a main.go file, which demonstrates logging at various levels using structured logging syntax.
package main
import (
"log/slog"
_ "git.eeqj.de/sneak/go-simplelog"
)
func main() {
// log structured data with slog as usual:
slog.Info("User login attempt", slog.String("user", "JohnDoe"), slog.Int("attempt", 3))
slog.Warn("Configuration mismatch", slog.String("expected", "config.json"), slog.String("found", "config.dev.json"))
slog.Error("Failed to save data", slog.String("reason", "permission denied"))
}
