Error logging

[frankrousseau]

Hello there,

On Node.js most error loggings are awful (ex: ENOENT error). Most of the time it requires a web research to find its meaning.

Is it possible to improve this in io.js ? I mean, if I don't find any technical constraints, may I propose a pull request about it?

There is now doc page about errors that explains these codes

[frankrousseau]

Could this information be displayed directly in the console (at least in a debug/development mode) ?

[frankrousseau]

Thank you for the link. It's very helpful.

[targos]

To log the error, you can use the errno module :

npm install errno
node -e "var fs = require('fs'); var codes = require('errno').code; try{ fs.readFileSync('/nosuchfile') } catch(e){ console.log(codes[e.code])  }"

full example here

It's good but it still requires an additional action. I think it's not very developer friendly.

Kinda a dupe of #92. I think the new error docs should be fine for now?

[frankrousseau]

Thank you @Fishrock123 for the pointer. I would say it looks more like a dup of #212.

[Fishrock123]

Oh yes. That too. Closing in favor of #212 @frankrousseau, please share your thoughts there. :)

[Fishrock123]

Reopening as #212 got closed and this can still improve, imo.

I think this is working as intended.

These are standard POSIX error codes, consult man errno on linux for a list ;)

We got new error docs a while ago. :)
