New parser request: pacman -Si

[brainwo]

I'm not sure if there is already parser that can help with this. Here is an example of pacman -Si output:

Hi there - it looks like two parsers that can work for this output would be the --kv parser or the --rpm-qi parser, which is also used for various other package index parsers, like --pkg-index-deb.

I can create a parser specifically for this format if these parsers don't work for specific output. I can probably modify the --rpm-qi parser and create a new alias for pacman -Si output.

A new parser would be nice. I see there are inconsistency on the use of null and "None", as well as "depends_on" values not being an array. And that "\n" inside the string too.

Also I want to mention there is this flag -Qi that does output the same as -Si, but it's for querying installed package. -Q is short hand for --query, and -S is for --sync while -i is for --info. (If this information matters. Perhaps for naming the command or for jc magic?)

Another thing is I got a question: If I got some new format I don't know what parser to use, how can I find what to use? Is there a list of how other formats looks like? I'm not familiar with how other format works, like other package managers for example (that surely isn't available in my distro of choice).
