I was already using soft output ports for writing controlled debugging information to log files, and it never occurred to me to simply add: (set-current-error-port ) to the top of my scripts! Incidentally, I've written a module that wraps /usr/bin/logger and a couple of macros that make defining any number of log functions a snip. Example usage: In cgi/my-script.scm... (use-modules (sebyte glog)) (load "lib/loggers.scm") ;prepare log functions (names, log ;files, priorities, port tags, padding) (quick-loggers "my-script.scm") ;define log functions with entry tag ;'my-script.scm' (info "foo") ;write to log file at priority info (alert "bar") ;write to log file at priority alert . . . Later on, in cgi/sub-script.scm... (quick-loggers "sub-script.scm") ;redefine log functions with entry tag ;'sub-script.scm' . . . Is this the sort of thing that might go down well on guile.sources?
