We are pleased to announce the first release of hpc, a new tool for
Haskell developers. Hpc records and displays Haskell program coverage.
It provides coverage information of two kinds: source coverage and
boolean-control coverage. Source coverage is the extent to which every
part of the program was used, measured at three different levels:
declarations (both top-level and local), alternatives (among several
equations or case branches) and expressions (at every level). Boolean
coverage is the extent to which each of the values True and False is
obtained in every syntactic boolean context (ie. guard, condition,
qualifier). Hpc displays both kinds of information in two different
ways: textual reports with summary statistics (hpc-report) and sources
with colour mark-up (hpc-source).
