class grapa.parse.parser_generic.FileParserGeneric

Bases: object

Methods to parse a file, organized with header key-values, then multicolumn data

__init__()

Methods

cast_curves(graph)	cast Curves as child class if specified by attr 'curve'
read(graph, attributes[, fileContent, ...])	Reads the file as a column-organized data file, with some headers lines at the beginning.
read_lines(filename, file_content, ...)	Read a file, returns the lines as a list of str

classmethod cast_curves(graph: Graph)

cast Curves as child class if specified by attr ‘curve’

classmethod read(graph: Graph, attributes: dict, fileContent=None, ifReplaceCommaByPoint=False, **kwargs)

Reads the file as a column-organized data file, with some headers lines at the beginning.

Parameters:

• graph – the graph to put the data in

• attributes –

  provided when intantiating the Graph object. Special keyword:

  • _singlecurve: parse all data into a single Curve object

• fileContent – if content to parse is given as a string, not from file read

• ifReplaceCommaByPoint – if numbers are formatted with ‘,’ instead of ‘.’

• kwargs –

  the following keywords are handled:

  • delimiter: if provided, assumed the values is the text delimiter.

  • delimiterHeaders: same as delimiter, but only for the headers section

  • lstrip: if provided, a lstrip function is applied to each line when parsing the file. Values: None (lstrip(None)), True, or ‘# ‘ etc.

classmethod read_lines(filename: str, file_content, replace_comma_dots: bool, lstriparg) → Tuple[List[str], str]

Read a file, returns the lines as a list of str

Parameters:

• filename – str of the filename to open

• file_content – None, or alternative content (if so, filename is not open).

• replace_comma_dots – bool

• lstriparg – if not None, .lstrip(*lstriparg) on lines. [str | None] | None]

Returns:

a list of str, one str per line in file
