sisl.io.Sile

class sisl.io.Sile(filename, *args, **kwargs)

Bases: Info, BaseSile

Base class for ASCII files

All ASCII files that needs to be added to the global lookup table can with benefit inherit this class.

By subclassing a Sile one can manually specify the buffer class used when passing a buffer_cls keyword argument. This enables one to overwrite buffer classes for custom siles.

Methods

close()

dir_file([filename, filename_base])

File of the current Sile

read(*args, **kwargs)

Generic read method which should be overloaded in child-classes

write(*args, **kwargs)

Generic write method which should be overloaded in child-classes

base_file

File of the current Sile

file

File of the current Sile

class InfoAttr(attr, regex, parser, doc='', updatable=False, default=None, found=False)

Bases: object

Holder for parsing lines and extracting information from text files

This consists of:

attr:

the name of the attribute This will be the sile.info. access point.

regex:

the regular expression used to match a line. If a str, it will be compiled as is to a regex pattern. regex.match(line) will be used to check if the value should be updated.

parser:

if regex.match(line) returns a match that is true, then this parser will be executed. The parser must be a function accepting two arguments:

def parser(attr, match)

where attr is this object, and match is the match done on the line. (Note that match.string will return the full line used to match against).

updatable:

control whether a new match on the line will update using parser. If false, only the first match will update the value

default:

the default value of the attribute

found:

whether the value has been found in the file.

__init__(attr, regex, parser, doc='', updatable=False, default=None, found=False)

copy()
doc
documentation()

Returns a documentation string for this object

read(*args, **kwargs)

Generic read method which should be overloaded in child-classes

Parameters

kwargs – keyword arguments will try and search for the attribute read_<> and call it with the remaining **kwargs as arguments.

write(*args, **kwargs)

Generic write method which should be overloaded in child-classes

Parameters

**kwargs – keyword arguments will try and search for the attribute write_ and call it with the remaining **kwargs as arguments.
