Gary, this is a feed back of my first use of log5. Previously I used log4CL with the daily rolling file appender pruducing a html file to be viewed with the browser. With browser update (F5) it is easy to read continously changing logfiles. This is what I am now doing with log5: (defun prepare-log-file (path) (with-open-file (s path :direction :output :if-exists :supersede) ;;stolen from Log4CL and modified (format s "<html><head> <title> Log5 Log Messages </title> <style type=\"text/css\"> <!-- body, table {font-family: arial,sans-serif; font-size: x-small;} th {background: #336699; color: #FFFFFF; text-align: left;} --> </style> </head> <body bgcolor=\"#FFFFFF\" topmargin=\"6\" leftmargin=\"6\"> <hr size=\"1\" noshade> Log session start at ~a <br> <br> <table cellspacing=\"0\" cellpadding=\"4\" border=\"1\" bordercolor=\"#224466\" width=\"100%\"> <tr> <th>Time</th> <th>Category</th> <th>Message</th> <th>Context</th>" (date-time-as-string (get-universal-time))))) (defparameter *logfile* "C:/lisp/log/mylog.html") (defoutput left "<tr><td>") (defoutput middle "</td><td>") (defoutput right "</td></td>") (defoutput time (formatted-current-time)) (defoutput html-message (html-escape message)) (prepare-log-file *logfile*) (start-sender 'mysender (stream-sender :location *logfile*) :category-spec (application pdf) :output-spec (left time middle category middle html-message middle context right))) The result is a nicely formatted table. It appears that log5 is very flexible, contexts are a cool feature ! 1. suggestion: A push-context command in a source file adds the same context to the list when the file is reloaded/recompiled. Wouldn't it be better to have something like push-new here ? 2. I wanted to give http://www.flogviewer.com/ a try for viewing the logfile since it has filters etc. The problem I have is that individual log messages can include many line breaks generated by I don't know what. This is not a problem when logging to a html file, but flogviewer expects one line per message. I tried everthing mentionned in cltl2 relating to *print-right-margin*, *print-miser-width* etc to switch this behaviour off, without success. I am not able to find out where the line breaks come from. Could you give me a hint please ?
