how are you configuring serilog in the code

dance?•7/17/23, 7:30 PM

at first sight config seems alright
except maybe pathFormat which i don't know where the hell that would point at
like maybe "folder\file.txt" could be ok, but starting with \ is probably not
even .\file.txt should be ok

SSaber how are you configuring serilog in the code

PontiacGTXOP•7/17/23, 7:31 PM

I am using

PontiacGTXOP•7/17/23, 7:31 PM

builder.Host.UseSerilog((context, configuration) => {  
    configuration.ReadFrom.Configuration(context.Configuration); });

builder.AddLoggers();

//after creating the app
//Add serilog to the pipeline
app.UseSerilogRequestLogging();

PontiacGTXOP•7/17/23, 7:32 PM

will it create the folder if it doesnt exist?

PontiacGTXOP•7/17/23, 7:32 PM

because the folder does not exist

PontiacGTXOP•7/17/23, 7:33 PM

the console works

dance?•7/17/23, 7:35 PM

in my experience it does create the folder

PontiacGTXOP•7/17/23, 7:35 PM

"pathFormat": "./Employeeslog-{Date}.txt",

PontiacGTXOP•7/17/23, 7:35 PM

like that?

dance?•7/17/23, 7:36 PM

is this win, linux, osx?

Ddance?is this win, linux, osx?

PontiacGTXOP•7/17/23, 7:37 PM

it will be on linux probably

PontiacGTXOP•7/17/23, 7:37 PM

my pc is windows

PontiacGTXOP•7/17/23, 7:37 PM

that's why

PontiacGTXOP•7/17/23, 7:37 PM

using a env variable would be cool

PontiacGTXOP•7/17/23, 7:38 PM

how do you replace a env variable in serilog

PontiacGTXOP•7/17/23, 7:38 PM

%varname%

PontiacGTXOP•7/17/23, 7:38 PM

or ${varname}

dance?•7/17/23, 7:42 PM

apparently it's %var%
although i've never used that

PontiacGTXOP•7/17/23, 7:48 PM

%var%/mypath/myfile.txt

Ddance?apparently it's %var% although i've never used that

PontiacGTXOP•7/17/23, 7:50 PM

what am i doing wrong?

TeBeCo•7/17/23, 7:57 PM

try not using the config file for the setup

TeBeCo•7/17/23, 7:57 PM

and do it all by code

TeBeCo•7/17/23, 7:57 PM

literally remove Configuration(context.Configuration);Configuration(context.Configuration);

TeBeCo•7/17/23, 7:58 PM

serilog's a fucking pain in the ass because of config ... which NO ONE EVER CHANGE

TeBeCo•7/17/23, 7:58 PM

and if you need to change a part of it I'd rather have a dedicated config

TeBeCo•7/17/23, 7:58 PM

it will make it soooooo either to debug/write/make flexible

PPontiacGTX how do you replace a env variable in serilog

TeBeCo•7/17/23, 7:59 PM

that also solves this

i will do that instead then

the fund part is that they call that Override, not Minimum level

that is for debugging only

probably to include it in the WriteTo

TeBeCo•7/17/23, 8:04 PM

you don't need them anymore

TeBeCo•7/17/23, 8:04 PM

that's actually the worst part of serilog

PontiacGTXOP•7/17/23, 8:04 PM

why?

TeBeCo•7/17/23, 8:04 PM

it's based on a magic string

TeBeCo•7/17/23, 8:04 PM

and you hope you have included the package

TeBeCo•7/17/23, 8:04 PM

you have no safety
