Overview

Builds and executes a git log query

This class provides a fluent interface for building complex git log queries.

Queries default to returning 30 commits; call #max_count with :all to return every matching commit. Calling #all adds the --all flag to include all refs in the search but does not change the number of commits returned.

The query is lazily executed when results are requested either via the modern #execute method or the deprecated Enumerable methods.

Examples:

Using the modern execute API

log = git.log.max_count(50).between('v1.0', 'v1.1').author('Scott')
results = log.execute
puts "Found #{results.size} commits."
results.each { |commit| puts commit.sha }

Constructor Details

#initialize(base, max_count = 30) ⇒ Log

Create a new Git::Log object

Examples:

git = Git.open('.')
Git::Log.new(git)

Parameters:

  • base (Git::Repository, Git::Base) —

    the git repository object

  • max_count (Integer, Symbol, nil) (defaults to: 30) —

    the number of commits to return, or :all or nil to return all

    Passing max_count to #initialize is equivalent to calling #max_count on the object.

#execute ⇒ Git::Log::Result

Executes the git log command and returns an immutable result object

This is the preferred way to get log data. It separates the query building from the execution, making the API more predictable.

Examples:

query = g.log.since('2 weeks ago').author('Scott')
results = query.execute
puts "Found #{results.size} commits"
results.each do |commit|
  # ...
end
