mangadap.util.parser.arginp_to_list(inp, evaluate=False, quiet=True)

Separate a list of comma-separated values in the input string to a list object.

Parameters

• inp (str or list) – Input string with a list of comma-separated values

• evaluate (bool) – (Optional) Attempt to evaluate the elements in the list using eval().

• quiet (bool) – (Optional) Suppress terminal output

Returns

The list of the comma-separated values

Return type

list

mangadap.util.parser.list_to_csl_string(flist)

Convert a list to a comma-separated string; i.e. perform the inverse of arginp_to_list().

Parameters

flist (list) – List to convert to a comma-separated string

Returns

String with the values in the input list converted to string, using str(), separated by commas

Return type

str

mangadap.util.parser.parse_dap_file_name(name)

Parse the name of a DAP file and return the plate, ifudesign, mode, binning type, and iteration number.

Parameters

name (str) – Name of the DAP file.

Returns

The plate, ifudesign, mode (‘RSS’ or ‘CUBE’), bin type, and iteration number of the DAP file, pulled from the name of the file.

Return type

int, int, str, str, int

Raises

• TypeError – Raised if name is not a string.

• ValueError – Raised if if the file name does not look like a DRP file because it does not include ‘manga-‘, ‘-BIN’, or ‘.fits’.

mangadap.util.parser.parse_drp_file_name(name)

Parse the name of a DRP file to provide the plate, ifudesign, and mode.

Parameters

name (str) – Name of the DRP file.

Returns

The plate, ifudesign, and mode (‘RSS’ or ‘CUBE’) of the DRP file pulled from the file name.

Return type

int, int, str

Raises

• TypeError – Raised if name is not a string.
