Output ANSI escape sequence in log

[suntong]

Hi,

First of all, I know there is a NewColorLogger, but I just want to avoid it and do ANSI escape sequence myself.

Now, please take a look

its output is not what I was expecting:

Any way to get my own ANSI escape sequence output works? thx

I believe this is a function of the logfmt format, and likely by design — you don't want unescaped escape sequences in your logs by default, as they can be an exploit vector.

Oh, thx.

if I don't use NewLogfmtLogger but a different one, say the term or file ones, would any of them works then?
