liblo-devel Mailing List for LibLO

Not the first time this comes up..

https://github.com/radarsat1/liblo/pull/43

Perhaps it's a good change.  It is unexpected behaviour for a
command-line program however, hence my hesitation.  But I think I'll
apply it, but rather using setvbuf() instead of fflush(). I added an
option "-L" to force line buffering.

alternatively you could just use the 'unbuffer' command (from 'expect')
to prevent line-buffering.

    unbuffer oscdump 9000 | cat -n

this has the slight drawback, that it will also turn stderr of oscdump
into stdout.

another solution is to use 'stdbuf' (from 'GNU coreutils'), which allows
you to adjust the lines-per-buffer per stream:

    stdbuf -o0 ./oscdump 9999 | cat -n

both solutions do not require any source-code change and/or recompile.

    Hello

    Just an one-liner for oscdump :

*** 61,66 ****
--- 61,67 ----
           lo_arg_pp((lo_type) types[i], argv[i]);
       }
       printf("\n");
+     fflush(stdout);

       return 0;
   }


    So now, "oscdump 9000 | cat -n" for numbering
    events make the job...
