class suitcase.nomad_camels_hdf5.FileManager(directory, new_file_each=True, file_extension=None)

Bases: object

Class taken from suitcase-nxsas!

A class that manages multiple files.

Parameters:

  • directory (str or Path) – The directory (as a string or as a Path) to create the files inside.

  • allowed_modes (Iterable) – Modes accepted by MultiFileManager.open. By default this is restricted to “exclusive creation” modes (‘x’, ‘xt’, ‘xb’) which raise an error if the file already exists. This choice of defaults is meant to protect the user for unintentionally overwriting old files. In situations where overwrite (‘w’, ‘wb’) or append (‘a’, ‘r+b’) are needed, they can be added here.

  • libraries. (This design is inspired by Python's zipfile and tarfile)

property artifacts
close()

close all files opened by the manager

get_last_file()

Returns the last file opened by the manager.

open(relative_file_path, entry_name, mode, **open_file_kwargs)
reserve_name(entry_name, relative_file_path)
class suitcase.nomad_camels_hdf5.Serializer(directory, file_prefix='{uid}-', plot_data=None, new_file_each=True, do_nexus_output=False, **kwargs)

Bases: DocumentRouter

Serialize a stream of documents to nomad_camels_hdf5.

Note

This can alternatively be used to write data to generic buffers rather than creating files on disk. See the documentation for the directory parameter below.

Parameters:

  • directory (string, Path, or Manager) –

    For basic uses, this should be the path to the output directory given as a string or Path object. Use an empty string '' to place files in the current working directory.

    In advanced applications, this may direct the serialized output to a memory buffer, network socket, or other writable buffer. It should be an instance of suitcase.utils.MemoryBufferManager and suitcase.utils.MultiFileManager or any object implementing that interface. See the suitcase documentation at https://nsls-ii.github.io/suitcase for details.

  • file_prefix (str, optional) – The first part of the filename of the generated output files. This string may include templates as in {proposal_id}-{sample_name}-, which are populated from the RunStart document. The default value is {uid}- which is guaranteed to be present and unique. A more descriptive value depends on the application and is therefore left to the user.

  • **kwargs (kwargs) – Keyword arugments to be passed through to the underlying I/O library.

artifacts

dict mapping the ‘labels’ to lists of file names (or, in general, whatever resources are produced by the Manager)

property artifacts
close()

Close all of the resources (e.g. files) allocated.

suitcase.nomad_camels_hdf5.clean_filename(filename)

cleans the filename from characters that are not allowed

Parameters:

filename (str) – The filename to clean.

suitcase.nomad_camels_hdf5.export(gen, directory, file_prefix='{uid}-', new_file_each=True, plot_data=None, **kwargs)

Export a stream of documents to nomad_camels_hdf5.

Note

This can alternatively be used to write data to generic buffers rather than creating files on disk. See the documentation for the directory parameter below.

Parameters:

  • gen (generator) – expected to yield (name, document) pairs

  • directory (string, Path or Manager.) –

    For basic uses, this should be the path to the output directory given as a string or Path object. Use an empty string '' to place files in the current working directory.

    In advanced applications, this may direct the serialized output to a memory buffer, network socket, or other writable buffer. It should be an instance of suitcase.utils.MemoryBufferManager and suitcase.utils.MultiFileManager or any object implementing that interface. See the suitcase documentation at https://nsls-ii.github.io/suitcase for details.

  • file_prefix (str, optional) – The first part of the filename of the generated output files. This string may include templates as in {proposal_id}-{sample_name}-, which are populated from the RunStart document. The default value is {uid}- which is guaranteed to be present and unique. A more descriptive value depends on the application and is therefore left to the user.

  • **kwargs (kwargs) – Keyword arugments to be passed through to the underlying I/O library.

Returns:

artifacts – dict mapping the ‘labels’ to lists of file names (or, in general, whatever resources are produced by the Manager)

Return type:

dict

Examples

Generate files with unique-identifier names in the current directory.

>>> export(gen, '')

Generate files with more readable metadata in the file names.

>>> export(gen, '', '{plan_name}-{motors}-')

Include the measurement’s start time formatted as YYYY-MM-DD_HH-MM.

>>> export(gen, '', '{time:%Y-%m-%d_%H:%M}-')

Place the files in a different directory, such as on a mounted USB stick.

>>> export(gen, '/path/to/my_usb_stick')
