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

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.
