Default finding package dependencies?

I'm not trying to be overly argumentative , and it's certainly possible my understanding is lacking in experience, but I think the key words there are "complete" and "everything". Let me give an example first.

Suppose I already have 80 packages installed. Now I want to install another 5 packages. Due to dependencies let's suppose another 15 packages are also installed that way. So I installed 20 packages today for a total of 100 overall. And of those 20, I may at first only know what 5 of them are (or maybe a few more, but not all 20).

Now if I use pkg_info to get a complete list of everything, I can't really tell which are the new packages can I ? If I display the install messages for everything, then 4 out of 5 messages are likely to be ones I've already seen; not very efficient.

I could, of course, get a directory of /var/db/pkg, grep it for today's date, and sort things out that way. But that is getting into what I referred to as "doing it by hand", not using pkg_info.

Now one other thing to add. During a pkg_add, there can be errors, failures, etc. It's primarily for this reason that I like to do a large pkg_add inside of script. It gives me a record of all that happened and I can see exactly what went wrong, if anything. So, given that I have the typescript file there, an added benefit is being able to search it for the install messages from only the new packages that were added today.

Does that make sense or am I still missing something? Thank you for your critiques, they are welcome.

Split from its parent thread. The original thread asked about displaying post-install messages. Discussion has morphed into focusing on identifying dependencies.

If dependency information is important to you, pkg_info(1) may not be the best choice. To get information on dependencies, you may want to play with the print-build-depends & print-run-depends targets mentioned in ports(7).

@ocicat: Thanks, it's good to know about that in general. However, I've never used ports, and my sense is that for my situation sticking with binary packages is the way to go. Given the reasoning in my last paragraph, the typescript file is a practical way for me to find targeted install messages without extra effort (until, of course, I delete the file )

@jggimi: I initially missed seeing your post in the parent thread. Thanks. I think my prior post in this thread replies to that as well.

The targets only required the tree to be installed; no building is required.

Thanks, that sounds most useful in general. And I think the general situation is what is most important in this thread. For example, it is probably what applies to daemonfowl, who started the parent thread.

Turning momentarily to my own situation, it turns out that in fact I do know what packages have been installed "today". That is because I've already downloaded the binary packages beforehand. (I do that as a result of slow Internet access.) So that explains why I wouldn't need to use ports for this. But again, most users' situations are probably quite different, and for them the ports tree may be a good way to go.

/var/log/messages records which packages have been installed recently.

Code:
Aug 10 22:04:27 ponderosa pkg_delete: Removed mupen64plus-core-1.99.5
Aug 10 23:00:03 ponderosa pkg_add: Added mupen64plus-core-1.99.5

Thank you! I didn't know about that, and it's good to know of "different roads to Rome", as they all have unique benefits and drawbacks, depending on the situation.
