.PP
|

The cache is a flat-text file, typically found at /var/lib/pkg/prt-get.cache.
|
||||
The first line records the cache format identifier, to prevent prt-cache from
|
||||
performing an operation using an incompatible cache format. The rest of the
|
||||
file consists of 13 lines per port: name, absolute path to the repository,
|
||||
version, release, description, dependencies, URL, optional dependencies,
|
||||
maintainer, readme, pre-install, post-install, and a blank (separator) line. If
|
||||
multiple ports with the same name appear among the active collections (as
|
||||
reported by \fBprt\-get dup\fP), only the first port will be listed in the
|
||||
cache.
|
||||
|

.PP
|
||||
Suppose you want to create a dependency map, like the one used by the setup
|
||||
program when installing from a CRUX ISO. One way to do so is to run \fBprt\-get
|
||||
cache\fP, and then process the resulting file with \fBawk(1)\fP:
|
||||
|
||||
.B
|
||||
tail -n +2 /var/lib/pkg/prt-get.cache | awk '((NR-1) % 13 < 2) { printf("%s : ",$0) } (NR %13 == 6) { gsub(/,/," ",$0); printf("%s\\n",$0) }' | awk -F: '/ \\/usr\\/ports\\/(core|opt|xorg) / { printf("%-25s : %s\\n",$1,$3) }' | tee -a setup.dependencies
|
||||
|
||||
.PP
|
||||
A slight variation will also extract all the optional dependencies of each
|
||||
port, in case you want to mimic Gentoo USE flags by editing the resulting file
|
||||
and referring to it in a wrapper script, as illustrated by the ffmpeg example
|
||||
in the \fBprt\-get\fP(8) man-page.

at least x264 and x265 (but not necessarily any of the other optional

dependencies) are present before trying to build ffmpeg. In the absence of such

a .softdeps config, the operation reverts to the behaviour of the preceding

example (maximal feature set). Implementing Gentoo USE flags with such an

awkward one-liner might draw criticism from advocates of the KISS principle.
