1. Caddy version (caddy version):
v2.4.1 h1:kAJ0JB5Xk5gPdTH/27S5cyoMGqD5lBAe9yZ8zTjVJa0=
2. How I run Caddy:
I’m just running a simple file server with the command and Caddyfile below.
a. System environment:
Windows 10 x64
b. Command:
caddy run -watch
c. Service/unit/compose file:
N/A
d. My complete Caddyfile or JSON config:
localhost
root * content
file_server
templates
3. The problem I’m having:
I’m running a very simple file server with Caddy but what bothers me is the structured JSON logging data in log output. Each line has some JSON at the end and some lines, like HTML template errors have very big blocks of it that make everything kind of unreadable.
This looks especially bad with line wrapping as is the default behavior on many terminals.
I would like to just disable printing of full JSON data at the end of each log message.
4. Error messages and/or full log output:
Here’s an example of what I mean. These are just the default messages that are printed when running and terminating Caddy, along with an HTML template error.
If you look at this with line wrapping on it will be particularly hard to read.

5. What I already tried:
format console says it’s supposed to be human readable, but it still appends JSON which is not what I want.
I tried format single_field common_log but it looks really old fashioned and clunky, and it doesn’t affect stuff like HTTP template errors and the stuff that prints on startup. What I want is simple human readable output, like v1 had, and the default formatter is so close to that except for the JSON dumping.
