(based on a feature request by samsep10l) a command you can put into a script
called by root's crontab, in order to mimic Slackware's tidy directory listings
(the main logdir only contains build logs of the latest installed packages;
other logs are moved to a separate directory). This particular command relies
on declaring \(dqlogfile /var/log/pkgbuild/%n__%v-%r.log\(dq and \(dqwritelog
enabled\(dq in \fBprt\-get.conf(5)\fP. Logs saved with a different filename
pattern will require slight adjustments to the command.

@ -128,13 +128,36 @@ replaced with the port's path, e.g. for port gcc in core, %p would be
and %n would be
.B gcc.
This allows you to have separate log files per port.
Separate log files for each version and release can be achieved using
the placeholders %v and %r, respectively. But if you want to enable
\fBrmlog_on_uninst\fP, it is best to avoid %p, %v, and %r when
specifying \fBlogfile\fP (as explained below).
.B rmlog_on_uninst
can be set to 'yes' or 'no'; when set to yes, uninstalling a package
will also try to delete its build log. Replacements in the template
\fBlogfile\fP will be made using the \fIcurrent values\fP from the
database of installed packages, and from the active repositories. If
log files exist with different values of %p, %v, or %r than what the
database and repositories provide, then the pattern substitutions will
fail to match the names of those logs, and this feature will be a no-op.
For example, suppose you specify the logfile pattern
\(dq%p/.buildlogs/%n__%v-%r.log\(dq, and you have a package installed
on your system through many versions, or after it has been moved from
opt to contrib. Uninstalling that package would leave behind all the
build logs except the latest. This pattern is also fragile with respect
to repository purges; if one of your installed ports is dropped from
the official repos, then either \(dq%p\(dq will expand to the path of
your personal overlay (you did make a copy, right?), or it will not
expand at all! See the EXAMPLES section of \fBprt\-get(8)\fP for
alternative ways to tidy up your directory of build logs.
.B readme
can be set to 'disabled', to suppress the notification after installing
a port with a README file; 'compact', to collect all the READMEs
into one post-transaction output; or 'verbose', to print separate
information about each port with a README file. See
.B prt-get(8)
.B prt\-get(8)
and especially the readme command how to read those README files using
prt-get.
