USER: ../console_handler.go:15:77: undefined: slog.Field
ASSISTANT: To fix the undefined `slog.Field` error in `console_handler.go`, we need to ensure that the `ConsoleHandler` implements the `slog.Handler` interface correctly. The `Log` method should be replaced with the `Handle` method, which takes a `slog.Record` as an argument.
Here is the necessary change:
console_handler.go
```go
<<<<<<< SEARCH
func (c *ConsoleHandler) Log(level slog.Level, message string, data ...slog.Field) error {
color.New(color.FgBlue).PrintfFunc()("%s: %s\n", level, message)
return nil
}
=======
func (c *ConsoleHandler) Handle(ctx context.Context, record slog.Record) error {
color.New(color.FgBlue).PrintfFunc()("%s: %s\n", record.Level, record.Message)
return nil
}
func (c *ConsoleHandler) Enabled(ctx context.Context, level slog.Level) bool {
return true
}
func (c *ConsoleHandler) WithAttrs(attrs []slog.Attr) slog.Handler {
return c
}
func (c *ConsoleHandler) WithGroup(name string) slog.Handler {
return c
}
>>>>>>> REPLACE
```
This change ensures that the `ConsoleHandler` conforms to the `slog.Handler` interface and uses the correct method signature.

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"))
}
