-Starting with Trac 0.10.4 (see [trac:#2844 #2844]), it is possible to set the output format for log entries. This can be done through the `log_format` option in [wiki:TracIni#logging-section trac.ini]. The format is a string which can contain any of the [http://docs.python.org/library/logging.html#logrecord-attributes Python logging Formatter variables]. Additonally, the following Trac-specific variables can be used:
- '''$(basename)s''':: The last path component of the current environment.
- '''$(path)s''':: The absolute path for the current environment.

 The default format is:

 log_format = Trac[$(module)s] $(levelname)s: $(message)s

 In a multi-project environment where all logs are sent to the same place (e.g. `syslog`), it makes sense to add the project name. In this example we use `basename` since that can generally be used to identify a project:
-{{{
+{{{#!ini
 log_format = Trac[$(basename)s:$(module)s] $(levelname)s: $(message)s
