The search service can find package by either name (apache), provides(webserver), absolute file names (/usr/bin/apache), binaries (gprof) or shared libraries (libXm.so.2) in standard path. It does not support multiple arguments yet...
The System and Arch are optional added filters, for example System could be "redhat", "redhat-7.2", "mandrake" or "gnome", Arch could be "i386" or "src", etc. depending on your system.
A newtype over 'Bool' with a better 'Vector' instance: 8x less memory, up to 3500x faster. The <https://hackage.haskell.org/package/vector vector> package represents unboxed arrays of 'Bool's spending 1 byte (8 bits) per boolean. This library provides a newtype wrapper 'Bit' and a custom instance of an unboxed 'Vector', which packs bits densely, achieving an __8x smaller memory footprint.__ The performance stays mostly the same; the most significant degradation happens for random writes (up to 10% slower). On the other hand, for certain bulk bit operations 'Vector' 'Bit' is up to 3500x faster than 'Vector' 'Bool'. === Thread safety * "Data.Bit" is faster, but writes and flips are not thread-safe. This is because naive updates are not atomic: they read the whole word from memory, then modify a bit, then write the whole word back. Concurrently modifying non-intersecting slices of the same underlying array may also lead to unexpected results, since they can share a word in memory. * "Data.Bit.ThreadSafe" is slower (usually 10-20%), but writes and flips are thread-safe. Additionally, concurrently modifying non-intersecting slices of the same underlying array works as expected. However, operations that affect multiple elements are not guaranteed to be atomic. === Similar packages * <https://hackage.haskell.org/package/bv bv> and <https://hackage.haskell.org/package/bv-little bv-little> do not offer mutable vectors. * <https://hackage.haskell.org/package/array array> is memory-efficient for 'Bool', but lacks a handy 'Vector' interface and is not thread-safe.
