class Gollum::Committer
Responsible for handling the commit process for a Wiki. It sets up the Git index, provides methods for modifying the tree, and stores callbacks to be fired after the commit has been made. This is specifically designed to handle multiple updated pages in a single commit.
Attributes
Gets a Hash of commit options.
Gets the instance of the Gollum::Wiki that is being updated.
Public Class Methods
Initializes the Committer.
wiki - The Gollum::Wiki instance that is being updated. options - The commit Hash details:
:message - The String commit message. :name - The String author full name. :email - The String email address. :parent - Optional Grit::Commit parent to this update. :tree - Optional String SHA of the tree to create the index from. :committer - Optional Gollum::Committer instance. If provided, assume that this operation is part of batch of updates and the commit happens later.
Returns the Committer instance.
# File lib/gollum-lib/committer.rb, line 28 def initialize(wiki, options = {}) @wiki = wiki @options = options @callbacks = [] end
Public Instance Methods
Public: The committer for this commit.
Returns a Grit::Actor.
# File lib/gollum-lib/committer.rb, line 52 def actor @actor ||= begin @options[:name] = @wiki.default_committer_name if @options[:name].to_s.empty? @options[:email] = @wiki.default_committer_email if @options[:email].to_s.empty? Grit::Actor.new(@options[:name], @options[:email]) end end
Adds a page to the given Index.
dir - The String subdirectory of the Gollum::Page without any
prefix or suffix slashes (e.g. "foo/bar").
name - The String Gollum::Page filename_stripped. format - The Symbol Gollum::Page format. data - The String wiki data to store in the tree map. allow_same_ext - A Boolean determining if the tree map allows the same
filename with the same extension.
Raises Gollum::DuplicatePageError if a matching filename already exists. This way, pages are not inadvertently overwritten.
Returns nothing (modifies the Index in place).

Adds a callback to be fired after a commit.
block - A block that expects this Committer instance and the created
commit's SHA1 as the arguments.
Returns nothing.
# File lib/gollum-lib/committer.rb, line 175 def after_commit(&block) @callbacks << block end
Writes the commit to Git and runs the #after_commit callbacks.
Returns the String SHA1 of the new commit.
# File lib/gollum-lib/committer.rb, line 161 def commit sha1 = index.commit(@options[:message], parents, actor, nil, @wiki.ref) @callbacks.each do |cb| cb.call(self, sha1) end sha1 end
Determine if a given file is scheduled to be deleted in the next commit for the given Index.
map - The Hash map:
key - The String directory or filename. val - The Hash submap or the String contents of the file.
path - The String path of the file including extension.
Returns the Boolean response.
# File lib/gollum-lib/committer.rb, line 214 def file_path_scheduled_for_deletion?(map, path) parts = path.split('/') if parts.size == 1 deletions = map.keys.select { |k| !map[k] } deletions.any? { |d| d == parts.first } else part = parts.shift if rest = map[part] file_path_scheduled_for_deletion?(rest, parts.join('/')) else false end end end
Public: References the Git index for this commit.
Returns a Grit::Index.
# File lib/gollum-lib/committer.rb, line 37 def index @index ||= begin idx = @wiki.repo.index if tree = options[:tree] idx.read_tree(tree) elsif parent = parents.first idx.read_tree(parent.tree.id) end idx end end

Determine if a given page (regardless of format) is scheduled to be deleted in the next commit for the given Index.
map - The Hash map:
key - The String directory or filename. val - The Hash submap or the String contents of the file.
path - The String path of the page file. This may include the format
extension in which case it will be ignored.
Returns the Boolean response.

Public: The parent commits to this pending commit.
Returns an array of Grit::Commit instances.

Update the given file in the repository's working directory if there is a working directory present.
dir - The String directory in which the file lives. name - The String name of the page or the stripped filename
(should be pre-canonicalized if required).
format - The Symbol format of the page.
Returns nothing.
