go logging registers as errors

project id: 271ed33d-be6b-40ce-96ba-504a94362dac howdy y'all. I'm hosting a go app on railway and it's been great but whenever I use go's default logger or charm log, all of my logs show up as errors instead of info. I have tried modifying the default logger's output to ensure it's not printing to standard err but it's still categorizing all of my logging as errors. Just wondering if anyone has any insight as to why this is happening.

Solution:

but making a new logger with stdout as its output seems to fix the problem

you are on the right track, sending logs to stdout instead of stderr would print them as info, can you please provide a minimal reproducible example for me to test

sowing•2mo ago

yeah i'll whip one up when i get back to my computer

Brody•2mo ago

sounds good!

sowing•2mo ago

ok i think this should do it

package main

import (
  "os"

  "github.com/charmbracelet/log"
)

func main() {
  log.Default().setOutput(os.Stdout)

  port := os.Getenv("PORT")
  if port == "" {
    port = "8080"
  }
  log.Infof("Listening on port: %s", port)
}

package main

import (
  "os"

  "github.com/charmbracelet/log"
)

func main() {
  log.Default().setOutput(os.Stdout)

  port := os.Getenv("PORT")
  if port == "" {
    port = "8080"
  }
  log.Infof("Listening on port: %s", port)
}

what version of go do you use

sowing•2mo ago

i tried both log.Default().setOutput() and log.setOutput() and both seem to send to stderr anyways 1.22

Brody•2mo ago

is cmp.Or a thing in that version?

sowing•2mo ago

it is indeed

Brody•2mo ago

little tip but it has nothing to do with logs - port := cmp.Or(os.Getenv("PORT"), "8080") saves 3 lines haha

sowing•2mo ago

that's pretty nice. never used that before lol

Brody•2mo ago

okay ill get to testing now

sowing•2mo ago

thanks so much!

Brody•2mo ago

well not off to a good start

sowing•2mo ago

oh that's totally my bad no lsp in discord code blocks capitals for public methods is right. I've been writing too much rust okay so it looks like you just can't set the default logger's output to stdout
