fparser.common.sourceinfo

Provides functions to determine whether a piece of Fortran source is free or fixed format. It also tries to differentiate between strict and “pyf” although I’m not sure what that is.

class fparser.common.sourceinfo.FortranFormat(is_free, is_strict, enable_f2py=False)[source]

Describes the nature of a piece of Fortran source.

Source can be fixed or free format. It can also be “strict” or “not strict” although it’s not entirely clear what that means. It may refer to the strictness of adherance to fixed format although what that means in the context of free format I don’t know.

Parameters:

is_free (bool) – True for free format, False for fixed.
is_strict (bool) – some amount of strictness.
enable_f2py (bool) – whether f2py directives are enabled or treated as comments (the default).

fparser.common.sourceinfo.get_source_info_str(source, ignore_encoding=True)[source]

Determines the format of Fortran source held in a string.

Parameters:: ignore_encoding (bool) – whether or not to ignore any Python-style encoding information in the first line of the file.
Returns:: a FortranFormat object.

Returns:: the Fortran format encoded as a string.
Return type:: str
