Instance Method Details

#create_authors ⇒ Object

Create the authors objects for the branch

  • creates an grouped_commits_array of arrays the size of the author_names array

  • sorts the commits by date and reveres this so the dates go from newest to olders

  • goes through the sorted commits and finds the index of that commit’s author in author_names array

  • adds that commit to the group_commits_array

  • takes each array in grouped_commits_array and creates an author object

def create_authors
  grouped_commits_array = Array.new(@author_names.size).map {|a| a = []}
  sorted_commits = @commits.sort_by {|k| k.date}.reverse
  sorted_commits.map {|commit|
    index = @author_names.index(commit.author.name)
    grouped_commits_array[index] << commit }
  grouped_commits_array.map {|grouped_commits| Author.new(grouped_commits)}
end

#get_author_names ⇒ Object

Gets a list authors who have committed to this branch

  • sort by authors name

  • remove the duplicates wih uniq

def get_author_names
  @commits.sort_by {|k| k.author.name.downcase}.collect {|commit| commit.author.name}.uniq
end

#get_total_lines_added_by_week ⇒ Object

Gets the total line added by week to the git repository TODO use this in an actual graph

# File 'lib/babygitter/repo_analyzer/branch.rb', line 74

def inspect
  %Q{#<Babygitter::Branch #{@total_commits} #{@name}>}
end

#map_commits_to_diff_state_by_week ⇒ Object

Conver to diff state through gruff and map those by week

  • call sorted_commits_by_week to sort commits by week into arrays

  • map those arrays of commits and convert them to diff states

  • flatten array of diff states so they are contained by week and not by commit.

TODO this method is incredibly slow due to going through the command line. Improve!

end

#sorted_commits_by_week ⇒ Object
