I am using Arch Linux. I want to do the same thing like apt-get source coreutils; is it possible to download sources with Pacman? I didn't find a solution in the man pages.
How can I get the source code of a package?
As already mentioned you can use the ABS (Arch Build System):
Install it using pacman: sudo pacman -S base-devel abs
then download the ABS tree: sudo abs
or get a specific package: sudo abs [package_name]
Then copy the package, whose source you want to have, from the local abs tree (e.g. /var/abs/core/findutils) to another directory, e.g. /home/blabla/abs
Then run makepkg:
if you only want to get the sources and don't want to build the package you can run makepkg -od
otherwise run makepkg -s, which will then handle all the package's dependencies automatically
watch out becaouse makepkg will overwrite your modifications, use makepkg -e to build your local sources instead
If you want to install the package you've built, run pacman -U name-of-package.xz
