Description: We use pmwiki extensively for documentation. When including a piece of code or a config file, we prefix the line with a space both for the hightlighting and for fixed width font.
e.g. here is part of the logrotate config for apache
sharedscripts postrotate if [ -f /var/run/apache.pid ]; then \ if [ -x /usr/sbin/invoke-rc.d ]; then \ invoke-rc.d apache reload > /dev/null; \ else \ /etc/init.d/apache reload > /dev/null; \ fi; \ fi; endscript
This displays badly because the \ is not shown as a \. Instead it appears to be escaping the newline. Ack!
This is a documented and wanted behaviour. See TextFormattingRules.

The easy solution is to escape the entire code or file excerpt, as in:
sharedscripts postrotate if [ -f /var/run/apache.pid ]; then \ if [ -x /usr/sbin/invoke-rc.d ]; then \ invoke-rc.d apache reload > /dev/null; \ else \ /etc/init.d/apache reload > /dev/null; \ fi; \ fi; endscript
This will also prevent any other wiki markups or WikiWords in the excerpt from interfering with the display of the text. You might also take a look at Cookbook.Beautifier for other ways of displaying code. --Pm
