Constant Summary collapse

DATE_FORMAT = 
"%Y/%m/%d:%H:%M:%S"
CHANGELIST_PATTERN =

Doesn’t work for empty messages, (Like 21358 in Aslak’s P4 repo)

/^Change \d+ by (.*)@.* on (.*)\n\n(.*)\n\nAffected files ...\n\n(.*)/m
CHANGELIST_PATTERN_NO_MSG =

But this one does

/^Change \d+ by (.*)@.* on (.*)\n\nAffected files ...\n\n(.*)/m
STATES = 
{
  "add" => RevisionFile::ADDED,
  "edit" => RevisionFile::MODIFIED,
  "delete" => RevisionFile::DELETED
