Is there a programatical way of getting package dependencies...

bitsdd · 2014-06-30 16:48:10

actually i'm building something for which i need the list of package dependencies for particular package to be installed, but unfortunately i'm not able to find anything as i tried:

sqlite3 core.db

but eventually get:

Error: file is encrypted or is not a database

and at this moment i don't what to do, if anyone can suggest??

Have you tried:

pacman -Si package

For example, I don't have gnome-shell installed and I can find out the listed dependencies with:

claire ~ % pacman -Si gnome-shell

I know, but i don't wanna do it through pacman(may be that's absurd)...
can't i use like core.db to extract such (package info) directly without the need of pacman.

Try expac.

Use libalpm (public header)

clfarron4: why the use of sudo in your example?

you could use pacman, e.g.

pacman -Sp --print-format '%n %v' foobar

or, as Cloudef said, use libalpm if you don't wanna parse pacman's output.

Also database files aren't sqlite db, but tar.gz files:

tar tf core.db

I automatically type sudo before pacman (habit).

I see your suggestion only lists dependencies left to install, rather than all dependencies.

oh right, it simply prints what would otherwise be installed, so any dependency already met won't be listed, indeed. (On the other hand, it is recursive, unlike the listing in -Si)
