gavo.grammars.kvgrammar module

A grammar parsing key-value pairs from plain text files.

class gavo.grammars.kvgrammar.KVIterator(grammar, sourceToken, **kwargs)[source]

Bases: gavo.grammars.common.FileRowIterator

is an iterator over a file containing key, value pairs.

Depending on the parent grammar, it returns the whole k,v record as one row or one pair per row.

class gavo.grammars.kvgrammar.KeyValueGrammar(parent, **kwargs)[source]

Bases: gavo.grammars.common.Grammar

A grammar to parse key-value pairs from files.

The default assumes one pair per line, with # comments and = as separating character.

yieldPairs makes the grammar return an empty docdict and {“key”:, “value”:} rowdicts.

Whitespace around key and value is ignored.
