ExpressionGroup

A group of expressions that match the same dimension. Expressions are evaluated

class ExpressionGroup(*expressions, smart=False)

A group of expressions that match the same dimension. Expressions are evaluated in the order they were added.

Parameters

• *expressions – List of expressions to match. High-priority expressions should be passed first.

• smart (bool, optional) – Whether to parse the text in a smart way. See smart_parse().

• expressions (Union[maha.rexy.Expression, ExpressionGroup]) –

compile_expressions(self)

add(self, *expression)

Add an expression to the group.

Parameters

• *expression – Expressions to add.

• expression (maha.rexy.Expression) –

Return type

None

join(self)

Returns non capturing group of the expressions.

Returns

Non capturing group of the patterns.

Return type

str

get_matched_expression(self, text)

Returns the expression that fully matches the text.

Parameters

text (str) – Text to match.

Returns

Expression that fully matches the text.

Return type

Expression

parse(self, text)

Parses the text.

Parameters

text (str) – Text to parse.

Yields

ExpressionResult – Extracted value.

Return type

Iterable[maha.rexy.ExpressionResult]

normal_parse(self, text)

Parse the input text and return the extracted values.

Parameters

text (str) – Text to parse.

Yields

ExpressionResult – Extracted value.

Return type

Iterable[maha.rexy.ExpressionResult]

smart_parse(self, text)

Parses the text. If a value matches two or more expressions, only the first expression parses the value, no value is matched more than once. This means high-priority expressions should be added to the group first.

Parameters

text (str) – Text to parse.

Yields

ExpressionResult – Extracted value.

Return type

Iterable[maha.rexy.ExpressionResult]
