abjad.configuration.list_all_functions(modules='abjad')[source]

Lists all public functions defined in modules.

>>> functions = abjad.list_all_functions(modules="abjad")
>>> names = [_.__name__ for _ in functions]
>>> # for name in sorted(names): name

abjad.configuration.yield_all_modules(package_name: str = 'abjad') → Iterator[ModuleType][source]: Yields all submodules in the package named package_name.

class abjad.configuration.Configuration[source]

Configuration.

Behavior at instantiation:

Looks for $HOME/.abjad/.
Creates $HOME/.abjad/ if directory does not exist.
Looks for $HOME/.abjad/abjad.cfg.
Creates $HOME/.abjad/abjad.cfg if file does not exist.
Parses $HOME/.abjad/abjad.cfg.
Provides default key-value pairs for pairs which fail validation.
Writes configuration changes to disk.
Creates Abjad output directory if directory does not exist.

Supports mutable mapping dictionary interface.

`abjad_directory`	Gets Abjad directory.
`abjad_output_directory`	Gets Abjad output directory.
`boilerplate_directory`	Gets Abjad boilerplate directory.
`configuration_directory`	Gets configuration directory.
`configuration_file_path`	Gets configuration file path.
`get`(arguments, *keywords)	Gets a key.
`get_lilypond_version_string`()	Gets LilyPond version string.
`home_directory`	Gets home directory.
`lilypond_log_file_path`	Gets LilyPond log file path.

abjad_directory: Gets Abjad directory.

abjad_output_directory: Gets Abjad output directory.

boilerplate_directory: Gets Abjad boilerplate directory.

configuration_directory

Gets configuration directory.

>>> configuration = abjad.Configuration()
>>> configuration.configuration_directory
PosixPath('/Users/trevor/.abjad')

Defaults to $HOME/{directory_name}.

Returns $TEMP/{directory_name} if $HOME is read-only or $HOME/{directory_name} is read-only.

Also caches the initial result to reduce filesystem interaction.

configuration_file_path

Gets configuration file path.

>>> configuration = abjad.Configuration()
>>> configuration.configuration_file_path
PosixPath('/Users/trevor/.abjad/abjad.cfg')

get(*arguments, **keywords)[source]: Gets a key.

get_lilypond_version_string() → str[source]

Gets LilyPond version string.

>>> configuration = abjad.Configuration()
>>> configuration.get_lilypond_version_string()  
'2.25.26'

home_directory

Gets home directory.

>>> configuration = abjad.Configuration()
>>> configuration.home_directory
PosixPath('/Users/trevor')

lilypond_log_file_path: Gets LilyPond log file path.
