General Package Map Builders

makePackageMap :: (Paragraph -> a) -> (a -> a -> a) -> [(FilePath, Compression)] -> IO (Map Text a)

create a map of (package name, extracted field) from a list of index files

NOTE: we could merge all the files into a single control and then run packageMap over that. We currently do it one control file at a time to avoid having all the control files loaded in memory at once. However, I am not sure that property is actually occuring anyway. So, this should be revisited.

packageMap :: (Paragraph -> a) -> (a -> a -> a) -> Control' Text -> Map Text a

create a map of (package name, max version) from a single control file

extractVersion :: Paragraph -> Maybe DebianVersion

extract the version number from a control paragraph
