migrate

Migrating IPython < 4.0 to Datalayer\n\nThis copies configuration and resources to their new locations in Datalayer\n\nMigrations:\n\n- .ipython/\n - nbextensions -> DATALAYER_DATA_DIR/nbextensions\n - kernels -> DATALAYER_DATA_DIR/kernels\n\n- .ipython/profile_default/\n - static/custom -> .datalayer/custom\n - nbconfig -> .datalayer/nbconfig\n - security/\n\n - notebook_secret, notebook_cookie_secret, nbsignatures.db -> DATALAYER_DATA_DIR\n\n - ipython_{notebook,nbconvert,qtconsole}config.py -> .datalayer/datalayer{name}_config.py

get_ipython_dir​

def get_ipython_dir() -> str

Return the IPython directory location.\n\nNot imported from IPython because the IPython implementation\nensures that a writable directory exists,\ncreating a temporary directory if not.\nWe don't want to trigger that when checking if migration should happen.\n\nWe only need to support the IPython < 4 behavior for migration,\nso importing for forward-compatibility and edge cases is not important.

Migrate a directory from src to dst

migrate_file​

def migrate_file(src: str,
                 dst: str,
                 substitutions: Optional[dict[Any, Any]] = None) -> bool

migrate_static_custom​

Migrate non-empty custom.js,css from src to dst\n\nsrc, dst are 'custom' directories containing custom.{js,css}

migrate_config​
