info on uninstalled package

Hello all,

Here is a newbie's question. I wanted to install wireguard. I found this projects which seems mature enough and it runs as a kernel module. They give simple instruction on how to install
pkg install wireguard

Simple enough. But I decided to do a pkg search before and I got this :

Code: 
[charon:: 20:57:55] [~] > pkg search  wireguard 
wireguard-2,1                  Meta-port for Wireguard
wireguard-go-0.0.20220316_2,1  WireGuard implementation in Go
wireguard-kmod-0.0.20220615    WireGuard implementation for the FreeBSD kernel
wireguard-tools-1.0.20210914_1 Fast, modern and secure VPN Tunnel
wireguard-tools-lite-1.0.20210914_1 Fast, modern and secure VPN Tunnel (lite flavor)
[charon:: 21:06:57] [~] >

or this version with the origin

Code: 
[charon:: 20:57:49] [~] > pkg search -o wireguard 
net/wireguard                  Meta-port for Wireguard
net/wireguard-go               WireGuard implementation in Go
net/wireguard-kmod             WireGuard implementation for the FreeBSD kernel
net/wireguard-tools            Fast, modern and secure VPN Tunnel
net/wireguard-tools            Fast, modern and secure VPN Tunnel (lite flavor)
[charon:: 20:57:55] [~] >

My first question is : how can I get more info on each one of those, a litle bit like brew would provide and without installing.

Second question, simply wireguard is the one suggested, but it says Meta-port what ever that means. And there is another package which has kmod in its name. Which one is the good one ? How can I tell ?

Freshports will tell you what build and runtime dependencies, among others, that are required.
 
Perfect, this answered all my questions. Here are my conclusions for other newbies that might read this.

Meta-port are effectively empty and points to other port. And one can see that the wireguard meta-port will in fact install wireguard-kmod and wireguard-tools packages.

There are also links to the project's web-page.

Thank you very much.
 
Thank you, this works too. Both solution are of useful indifferent ways. Unless I cannot read correctly, which happens way too often, pkg search -f wireguard does not explicitly give the dependences. It says :
This package does not contain anything by itself - it is a "meta-port" that
depends on other wireguard packages.

But, does not point to wireguard-kmod.
 
pkg rquery %do wireguard

Code: 
   Multiline patterns:
     %d[nov]
             Expands to the list of dependencies for the matched package,
             where n stands for the package name, o for the package origin,
             and v for the package version.

Code: 
root@fbsd-test:~ # pkg rquery %do wireguard
net/wireguard-tools
net/wireguard-kmod

You can also just look at the port's Makefile (this one isn't very complex):
Code: 
RUN_DEPENDS=	wg-quick:net/wireguard-tools
{...}
RUN_DEPENDS+=	${KMODDIR}/if_wg.ko:net/wireguard-kmod

A more "complete" list could be found with the all-depends-list target (see ports(7)):
Code: 
root@fbsd-test:/usr/ports/net/wireguard # make all-depends-list
/usr/ports/ports-mgmt/pkg
/usr/ports/net/wireguard-tools
/usr/ports/devel/gmake
/usr/ports/devel/gettext-runtime
/usr/ports/print/indexinfo
/usr/ports/shells/bash
/usr/ports/devel/bison
/usr/ports/devel/m4
/usr/ports/print/texinfo
/usr/ports/misc/help2man
/usr/ports/devel/p5-Locale-gettext
/usr/ports/devel/gettext-tools
/usr/ports/devel/libtextstyle
/usr/ports/lang/perl5.32
/usr/ports/devel/p5-Locale-libintl
/usr/ports/converters/libiconv
/usr/ports/converters/p5-Text-Unidecode
/usr/ports/textproc/p5-Unicode-EastAsianWidth
/usr/ports/devel/readline
/usr/ports/net/wireguard-kmod

But this is going to show a bunch of build dependencies too. The package isn't going to depend on those.
 
As shown above pkg-rquery(8) is used for "precise queries", targeting a specific remote pkg-name; also there is the pkg alias rall-depends. Note that where pkg-query(8) searches the local pkg repository/database, both pkg-rquery(8) and pkg-search(8) apply to the remote repository.

pkg-search(8) is more of a general nature where it targets a pattern. As such pkg search -f wireguard also returns info about the alternative Go implementation of wireguard, net/wireguard-go. With that in mind, pkg-search(8) can retrieve the dependencies with an Output Modifier Option (-Q query modifier):
Code: 
[1] % pkg search -Q depends-on wireguard
wireguard-2,1
Comment        : Meta-port for Wireguard
Depends on     :
    wireguard-tools-1.0.20210914_1
    wireguard-kmod-0.0.20220615
wireguard-go-0.0.20220316_2,1

wireguard-kmod-0.0.20220615
Comment        : WireGuard implementation for the FreeBSD kernel
wireguard-tools-1.0.20210914_1

Depends on     :
    bash-5.1.16
wireguard-tools-lite-1.0.20210914_1
Comment        : Fast, modern and secure VPN Tunnel (lite flavor)
[2] % pkg rall-depends wireguard
wireguard-tools-1.0.20210914_1
wireguard-kmod-0.0.20220615
[3] % pkg alias rall-depends
rall-depends          'rquery %dn-%dv'
In commands [2] & [3] the pkg alias rall-depends (defined in /etc/pkg.conf) works as a substitute for the specific pkg rquery.

Instead of pkg search -Q depends-on wireguard you can use pkg search --depends-on wireguard or pkg search -d wireguard. These formats have the (small) advantage—in this case—that you can see the direct recursive dependencies of net/wireguard-tools: it depends on shells/bash. Note however that only happens to work here (for only one dependency level deeper) because net/wireguard-tools is also being matched by "wireguard" in pkg search -Q depends-on wireguard; therefore, it does not show on which packages shells/bash depends.

If you want a listing of all recursive dependencies of a remote package then, you'll have to write your own script for that; you could make use of pkg-query(8):
Rich (BB code): 
%?[drCOLBbA]
         Returns 0 if the list is empty and 1 if the list has information
         to display

         d    for dependencies
         [...]

For local packages—already installed and administered to the local package database—you can rely on pkg-query(8) or all-depends-list target (see ports(7)), as mentioned in the previous message. Note also the various options that predefined pkg aliases will give you: see pkg alias | grep depend. However, for recursive dependencies you have to resort to script programming or make use of databases/sqlite3/. To get started for this specific topic, have a look at the SQL query for the reverse dependencies of a package here.
 
Thank you, as ever RTFM ( man pkg-search ) is the key.

Effectively, pkg search -do gives a nice output :
