Re: my attempt to find operating system


Thanks for your help, American Citizen.

Below is a script working either on Mac OS, Windows or Linux, whatever is the name and the content of the log.
I'm quiet sure it could be simplified, maybe using 'select' function.

f=default(logfile);
\v
k=readstr(f);

for(i=1, +oo, iferr(b=strsplit(k[i]," "); if(setsearch(b,"darwin")>0, print("MacOS"); return, if(setsearch(b,"mingw")>0,  print("Windows");return, if(setsearch(b,"linux")>0, print("Linux"); return))), E, print("OS non déterminé"); return));

default(log,0);
Bill, could you create a new function called, let say, 'OSType' and returning "MacOS", "Linux" or "Windows" as string?

In addition, is there a corresponding function for \v, as there is defaut(log,x) for \l?
With \v, there is an annoying display of the returned information, like with \l, but no display with "default(log,x);".😉

Thanks a lot to all replyers.

You could parse this line for the operating system.

and then turn off logging again

? \l
   log = 0 (off)
   [logfile was "pari.log"]
