montepy.input_parser.mcnp_input.Input

class montepy.input_parser.mcnp_input.Input(input_lines, block_type, input_file=None, lineno=None)

Bases: ParsingNode

Represents a single MCNP “Input” e.g. a single cell definition.

Parameters:

• input_lines (list) – the lines read straight from the input file.

• block_type (BlockType) – An enum showing which of three MCNP blocks this was inside of.

• input_file (MCNP_InputFile) – the wrapper for the input file this is read from.

• lineno (int) – the line number this input started at. 1-indexed.

Methods:

format_for_mcnp_input(mcnp_version)	Creates a string representation of this input that can be written to file.
tokenize()	Tokenizes this input as a stream of Tokens.

Attributes:

SPECIAL_COMMENT_PREFIXES	Prefixes for special comments like tally comments.
block_type	Enum representing which block of the MCNP input this came from.
input_file	The file this input file was read from.
input_lines	The lines of the input read straight from the input file
input_text
lexer	The current lexer being used to parse this input.
line_number	The line number this input started on.

format_for_mcnp_input(mcnp_version)

Creates a string representation of this input that can be written to file.

Parameters:

mcnp_version (tuple) – The tuple for the MCNP version that must be exported to.

Returns:

a list of strings for the lines that this input will occupy.

Return type:

list

tokenize()

Tokenizes this input as a stream of Tokens.

This is a generator of Tokens. This is context dependent based on block_type().

• In a cell block CellLexer is used.

• In a surface block SurfaceLexer is used.

• In a data block DataLexer is used.

Returns:

a generator of tokens.

Return type:

Token

SPECIAL_COMMENT_PREFIXES = ['fc', 'sc']

Prefixes for special comments like tally comments.

Return type:

list

property block_type

Enum representing which block of the MCNP input this came from.

Return type:

BlockType

property input_file

The file this input file was read from.

Return type:

MCNP_InputFile

property input_lines

The lines of the input read straight from the input file

Return type:

list

property input_text

property lexer

The current lexer being used to parse this input.

If not currently tokenizing this will be None.

Return type:

MCNP_Lexer

property line_number

The line number this input started on.

This is 1-indexed.

Return type:

int
