regex - How to make the regexp ignore a new line in python? -

-
i use regex that return(\s+([^"\n;]+))?; in order match return statement in obj-c,but when use through python this: re.sub(r'return(\s+([^"\n;]+))?;',r'{\g<0>}',str(content)) i find match statement //please {return [self funca];} and make code error.how can deal ? i think issue regex has \s matches whitespace. you might want match literal spaces or tabs [ \t] : r'return([ \t]+([^"\n;]+))?;' ( demo ) or - better: r'return[ \t]+[^"\n;]*;' see the regex demo

c# - write-to not working from AppSettings with Serilog 2.1 -

-
i used serilog 1.x , following worked there: in code: log.logger = new loggerconfiguration().readfrom.appsettings().createlogger(); in app.config: <add key="serilog:write-to:rollingfile.pathformat" value="c:\temp\myservice\log-{date}.log" /> but serilog 2.1 seems write-to isn't working app.config. when put them straight code works want them app.config. wrong code/app.config? i luckily resolved myself. seems in 2.x version there need serilog:using every sink in app.config. added following use rollingfile , seq: <add key="serilog:using:rollingfile" value="serilog.sinks.rollingfile" /> <add key="serilog:using:seq" value="serilog.sinks.seq" /> and both rolling files , seq works.
