pkg_noisrev–a fast way to summarize installed versions of FreeBSD packages.

pkg_noisrev [options]

The pkg_noisrev utility is a very fast version of pkg_version program that ships with FreeBSD. Consider the example from virtualized FreeBSD 8.2 (with 696 installed packages) where virtual hdd is a main performance bottle neck:

% time pkg_version
[...]
21.006u 68.076s 1:59.73 74.3%   403+713k 1155+0io 3pf+0w

% time pkg_noisrev
[...]
12.261u 10.249s 0:26.29 85.5%   95+1128k 0+0io 0pf+0w

pkg_noisrev is basically ~ 4.6 times faster. It achieves this speed by doing its work in several parallel threads + making some not-so-interesting tricks of extracting version strings from Makefiles.

pkg_noisrev also adds filtering to the output, thus you can, for example, only see out of sync packages. If you are a portmaster user, you may like --likeportmaster option (I do!).

The options are as follows:

–config-dirs

List all possible locations for the configuration file. The first found wins.

–config NAME

The name of the configuration file. If it contains / in it, the list from --config-dirs is ignored.

-V

Show version and exit.

-v

Tries to create a log in /tmp/pkg_noisrev.log file.

–pkg-dir STR

Set the alternate package db directory.

–ports-dir STR

Set the alternate ports db directory.

–outofsync

Filter all but out of sync packages.

–missing

Filter all but packages that doesn’t exists in ports.

–likeportmaster

Print like (but not quite) “portmaster -L”.

(Only if you are not installing the gem.)

pkg_noisrev ships with a shared library (the comparator of a 2 versions-as-a-string that was extracted from pkg_version sources) which must be compiled before you can use the program.

cd to a directory with pkg_noisrev sources and type:

% rake mydll:default

Then run bin/pkg_noisrev or make a symlink to it in one of your directories in PATH.

pkg_noisrev looks for its configuration at 3 places at start up.

1. At PKG_NOISREV_CONF env variable. (Its format is exactly similar to CL options.)

2. At the configuration file. Its default name is pkg_noisrev.yaml and it can be stored in several system directories which are observable by --config--dirs CL option.

3. At command line.

Higher number levels overrides the values from lower number levels.

The configuration file must be in YAML format. Look into `gem env gemdir`/gems/pkg_noisrev-x.y.z/etc/ directory for samples.
