v0.93 Windows - Cannot specify absolute path in log_file

[AnthonyBe]

I am trying to config AGH to generate a local log file rather than log to Windows Event Log by populating the log_file settnig in the config file. I can't seem to get it to work and everything permutation I try results in the AGH service not starting and an error being logged:

yaml: line 70: found unknown escape character

NOTE: The documentation for this setting states:
log_file — Path to the log file. If empty, writes to stdout, if syslog -- system log (or eventlog on Windows).
https://github.com/AdguardTeam/AdGuardHome/wiki/Configuration

Steps to reproduce

1. Change log_file setting from "" to
2. log_file: "c:\install\AdGuardHome"
3. log_file: "c:\install\AdGuardHome"
4. log_file: "c:\install\AdGuardHome\AGH.log"
   none of which worked and all generated the above error.

What finally worked was "log_file: AGH.log"

Could I suggest either:

1. fixing the Wiki and remove the word 'path' and just say 'filename', OR
2. Fix AGH so you can actually put a path in the setting.

try either c:/install/AdGuardHome or c:\\install\\AdGuardHome

Sorry, forgot to mention that I'd tried c:/install/AdGuardHome (I'm used to working with UNIX ports to Windows forgetting to change forward-slashes to back-slashes :)

Both c:/install/AdGuardHome and c:\\install\\AdGuardHome failed with same error as original post.

Yeah, on Windows there's an issue with specifying an absolute path which we should fix.

Even if you make it a valid YAML (by removing quotes or escaping \) it won't work anyway:

2019/02/27 15:06:56 cannot create a log file: open c:\AdGuardHome_v0.93_Windows\
c:\adguard.log: The filename, directory name, or volume label syntax is incorrec
