PEP 8 planning

Migration of Pyparsing's API over to PEP-8 will be a multi-step process, involving synonym definitions of many methods, method arguments, and module-level variables to provide a migration path for existing pyparsing users. These include:

• no change to existing class names, as they are already PEP-8 compliant

• no change to pyparsing_unicode or pyparsing_common; even though these are classes, their intent is to serve as module-like namespaces, so they will retain module naming style

• conversion of non-PEP-8 methods to classes (while redefining current names as synonyms to the new names):

  • delimitedList -> DelimitedList
  • oneOf -> OneOf
  • dictOf -> DictOf
  • infixNotation -> InfixNotation countedArray->CountedArray matchPreviousLiteral -> MatchPreviousLiteral
  • matchPreviousExpr -> MatchPreviousExpr
  • originalTextFor -> OriginalTextFor
  • locatedExpr -> LocatedExpr
  • nestedExpr -> NestedExpr
  • indentedBlock -> IndentedBlock

  This conversion will also make grammar definitions more consistent in appearance, as most will use just class names, not a mix of class names and method names

• no change to:

  • alphas
  • nums
  • alphanums
  • hexnums
  • printables
  • col
  • lineno
  • line

• renaming (with retained synonyms):

  • quotedString -> quoted_string
  • dblQuotedString -> dbl_quoted_string
  • sglQuotedString -> sgl_quoted_string
