montepy.input_parser.parser_base module#

class montepy.input_parser.parser_base.MCNP_Parser#

Bases: Parser

classifier(p)#

The classifier of a data input.

This represents the first word of the data input. E.g.: M4, IMP:N, F104:p

Return type:: ClassifierNode

classifier_phrase(p)#

A classifier with its padding.

Return type:: ClassifierNode

data_prefix(p)#

debugfile = None#

equals_sign(p)#

The seperation between a key and value for a parameter.

Returns:: a str ValueNode
Return type:: ValueNode

errok()#: Clear the error status

error(token)#

Default error handling.

Puts the data into a queue that can be pulled out later for one final clear debug.

Parameters:: token (Token) – the token that broke the parsing rules.

file_atom(p)#

file_name(p)#

A file name.

Return type:: str

file_phrase(p)#

A file name with or without its padding.

Returns:: a str ValueNode.
Return type:: ValueNode

identifier_phrase(p)#

A non-zero number with or without padding converted to int.

Returns:: an int ValueNode
Return type:: ValueNode

index_position(value)#

line_position(value)#

log = <montepy.input_parser.parser_base.SLY_Supressor object>#

modifier(p)#

A character that modifies a classifier, e.g., *TR.

Returns:: the modifier
Return type:: str

null_ident_phrase(p)#

A zero number with or without its padding, for identification.

Returns:: an int ValueNode
Return type:: ValueNode

null_phrase(p)#

A zero number with or without its padding.

Returns:: a float ValueNode
Return type:: ValueNode

number_phrase(p)#

A non-zero number with or without padding.

Returns:: a float ValueNode
Return type:: ValueNode

number_sequence(p)#

A list of numbers.

Return type:: ListNode

numerical_phrase(p)#

Any number, including 0, with its padding.

Returns:: a float ValueNode
Return type:: ValueNode

padding(p)#

Anything that is not semantically significant: white space, and comments.

Returns:: All sequential padding.
Return type:: PaddingNode

param_seperator(p)#

The seperation between a key and value for a parameter.

Returns:: a str ValueNode
Return type:: ValueNode

parameter(p)#

A singular Key-value pair.

Returns:: the parameter.
Return type:: SyntaxNode

parameters(p)#

A list of the parameters (key, value pairs) for this input.

Returns:: all parameters
Return type:: ParametersNode

parse(token_generator, input=None)#

Parses the token stream and returns a syntax tree.

If the parsing fails None will be returned. The error queue can be retrieved from parser.log.clear_queue().

Parameters:

token_generator (generator) – the token generator from lexer.tokenize.
input (Input) – the input that is being lexed and parsed.

Return type:

SyntaxNode

part(p)#

particle_type(p)#

precedence = (('left', 'SPACE'), ('left', 'TEXT'))#

restart()#

Clears internal state information about the current parse.

Should be ran before a new object is parsed.

shortcut_phrase(p)#

A complete shortcut, which should be used, and not shortcut_sequence.

Returns:: the parsed shortcut.
Return type:: ShortcutNode

shortcut_sequence(p)#

A shortcut (repeat, multiply, interpolate, or jump).

Returns:: the parsed shortcut.
Return type:: ShortcutNode

shortcut_start(p)#

text_phrase(p)#

A string with or without its padding.

Returns:: a str ValueNode.
Return type:: ValueNode

class montepy.input_parser.parser_base.MetaBuilder(classname, bases, attributes)#

Bases: ParserMeta

Custom MetaClass for allowing subclassing of MCNP_Parser.

Added in version 0.2.0: This was added with the major parser rework.

Note: overloading functions is not allowed.

mro()#: Return a type’s method resolution order.

class montepy.input_parser.parser_base.SLY_Supressor#

Bases: object

This is a fake logger meant to mostly make warnings dissapear.

Added in version 0.2.0: This was added with the major parser rework.

clear_queue()#

Clears the error queue and returns all errors.

Returns a list of dictionaries. The dictionary has the keys: “message”, “token”, “line.

Returns:: A list of the errors since the queue was last cleared.
Return type:: list

critical(msg, *args, **kwargs)#

debug(msg, *args, **kwargs)#

error(msg, *args, **kwargs)#

info(msg, *args, **kwargs)#

parse_error(msg, token=None, lineno=0, index=0)#

Adds a SLY parsing error to the error queue for being dumped later.

Parameters:

msg (str) – The message to display.
token (Token) – the token that caused the error if any.
lineno (int) – the current lineno of the error (from SLY not the file), if any.

warning(msg, *args, **kwargs)#
