Overview

This class represents a Xcode project document.

It can be used to manipulate existing documents or even create new ones from scratch.

An Xcode project document is a plist file where the root is a dictionary containing the following keys:

  • archiveVersion: the version of the document.

  • objectVersion: the version of the objects description.

  • classes: a key that apparently is always empty.

  • objects: a dictionary where the UUID of every object is associated to its attributes.

  • rootObject: the UUID identifier of the root object (Object::PBXProject).

Every object is in turn a dictionary that specifies an ‘isa` (the class of the object) and in accordance to it maintains a set attributes. Those attributes might reference one or more other objects by UUID. If the reference is a collection, it is ordered.

The Project API returns instances of Object::AbstractObject which wrap the objects described in the Xcode project document. All the attributes types are preserved from the plist, except for the relationships which are replaced with objects instead of UUIDs.

An object might be referenced by multiple objects, an when no other object is references it, it becomes unreachable (the root object is referenced by the project itself). Xcodeproj takes care of adding and removing those objects from the ‘objects` dictionary so the project is always in a consistent state.

Class Method Details

.open(path) ⇒ Object

Opens the project at the given path.

Examples:

Opening a project

Project.open("path/to/Project.xcodeproj")

Parameters:

  • path (Pathname, String) —

    The path to the Xcode project document (xcodeproj).

Raises:

  • If the project versions are more recent than the ones know to Xcodeproj to prevent it from corrupting existing projects. Naturally, this would never happen with a project generated by xcodeproj itself.

  • If it can’t find the root object. This means that the project is malformed.

Instance Method Details

#==(other) ⇒ Boolean

TODO:

If ever needed, we could also compare ‘uuids.sort` instead.

A fast way to see if two Xcodeproj::Project instances refer to the same projects on disk. Use this over #eql? when you do not need to compare the full data.

This shallow comparison was chosen as the (common) ‘==` implementation, because it was too easy to introduce changes into the Xcodeproj code-base that were slower than O(1).

Returns:

  • (Boolean) —

    whether or not the two ‘Project` instances refer to the same projects on disk, determined solely by #path and `root_object.uuid` equality.

135
 
# File 'lib/xcodeproj/project.rb', line 133

def ==(other)
  other && path == other.path && root_object.uuid == other.root_object.uuid
end

#[](group_path) ⇒ PBXGroup

Returns a group at the given subpath relative to the main group.

Examples:

frameworks = project['Frameworks']
frameworks.name #=> 'Frameworks'
main_group.children.include? frameworks #=> True

Parameters:

  • group_path (String) —

    @see MobileCoreServices

Returns:

  • (PBXGroup) —

    the group at the given subpath.

#add_build_configuration(name, type) ⇒ XCBuildConfiguration

Adds a new build configuration to the project and populates its with default settings according to the provided type.

Parameters:

  • name (String) —

    The name of the build configuration.

  • type (Symbol) —

    The type of the build configuration used to populate the build settings, must be :debug or :release.

#build_settings(name) ⇒ Hash

Returns the build settings of the project wide build configuration with the given name.

Parameters:

  • name (String) —

    The name of a project wide build configuration.

Returns:

  • (Hash) —

    The build settings.

end

#eql?(other) ⇒ Boolean

Note:

This operation can be extremely expensive, because it converts a ‘Project` instance to a hash, and should only ever be used to determine wether or not the data contents of two `Project` instances are completely equal.

To simply determine wether or not two Xcodeproj::Project instances refer to the same projects on disk, use the #== method instead.

Compares the project to another one, or to a plist representation.

Parameters:

  • other (#to_hash) —

    the object to compare.

Returns:

  • (Boolean) —

    whether the project is equivalent to the given object.

# File 'lib/xcodeproj/project.rb', line 151

def eql?(other)
  other.respond_to?(:to_hash) && to_hash == other.to_hash

Returns:

  • (PBXGroup) —

end

#generate_available_uuid_list(count = 100) ⇒ void

Note:

This method might generated a minor number of uniques UUIDs than the given count, because some might be duplicated a thus will be discarded.

This method returns an undefined value.

Pre-generates the given number of UUIDs. Useful for optimizing performance when the rough number of objects that will be created is known in advance.

Parameters:

  • count (Integer) (defaults to: 100) —

    the number of UUIDs that should be generated.

  uniques = (new_uuids - (@generated_uuids + uuids))
  @generated_uuids += uniques
  @available_uuids += uniques
end

#generate_uuid ⇒ String

Note:

UUIDs are not guaranteed to be generated unique because we need to trim the ones generated in the xcodeproj extension.

Note:

Implementation detail: as objects usually are created serially this method creates a batch of UUID and stores the not colliding ones, so the search for collisions with known UUIDS (a performance bottleneck) is performed less often.

Generates a UUID unique for the project.

Returns:

  • (String) —

    A UUID unique to the project.

#new(klass) ⇒ AbstractObject

Creates a new object with a suitable UUID.

#new_from_plist(uuid, objects_by_uuid_plist, root_object = false) ⇒ AbstractObject

Note:

This method is used to generate the root object from a plist. Subsequent invocation are called by the Xcodeproj::Project::Object::AbstractObject#configure_with_plist. Clients of Xcodeproj are not expected to call this method.

Creates a new object from the given UUID and ‘objects` hash (of a plist).

The method sets up any relationship of the new object, generating the destination object(s) if not already present in the project.

Parameters:

  • uuid (String) —

    The UUID of the object that needs to be generated.

  • objects_by_uuid_plist (Hash {String => Hash}) —

    The ‘objects` hash of the plist representation of the project.

  • root_object (Boolean) (defaults to: false) —

    Whether the requested object is the root object and needs to be retained by the project before configuration to add it to the ‘objects` hash and avoid infinite loops.

This method returns an undefined value.

Replaces all the UUIDs in the project with deterministic MD5 checksums.

#recreate_user_schemes(visible = true) ⇒ void

This method returns an undefined value.

Recreates the user schemes of the project from scratch (removes the folder) and optionally hides them.

Parameters:

  • visible (Bool) (defaults to: true) —

    Wether the schemes should be visible or hidden.

#reference_for_path(absolute_path) ⇒ PBXFileReference, Nil

Returns the file reference for the given absolute path.

Parameters:

  • absolute_path (#to_s) —

    The absolute path of the file whose reference is needed.

Returns:

  • (PBXFileReference) —

    The file reference.

  • (Nil) —

    If no file reference could be found.

#save(save_path = nil) ⇒ void

This method returns an undefined value.

Serializes the project in the xcodeproj format using the path provided during initialization or the given path (‘xcodeproj` file). If a path is provided file references depending on the root of the project are not updated automatically, thus clients are responsible to perform any needed modification before saving.

Examples:

Saving a project

project.save
project.save

Parameters:

  • path (String, Pathname) —

    The optional path where the project should be saved.

end

#sort(options = nil) ⇒ void

This method returns an undefined value.

Sorts the project.

Parameters:

  • options (Hash) (defaults to: nil) —

    the sorting options.

Options Hash (options):

  • :groups_position (Symbol) —

    the position of the groups can be either ‘:above` or `:below`.

#to_hash ⇒ Hash

end

#to_tree_hash ⇒ Hash

Converts the objects tree to a hash substituting the hash of the referenced to their UUID reference. As a consequence the hash of an object might appear multiple times and the information about their uniqueness is lost.

This method is designed to work in conjunction with Hash#recursive_diff to provide a complete, yet readable, diff of two projects not affected by differences in UUIDs.

Returns:

  • (Hash) —

    a hash representation of the project different from the plist one.
