== FeatureList xText EBNF Version 2.0 ==
 * '''Core Features''':

 1. BNF front-end (Parser, Lexer, Linker, etc.)
 1. translates a textual representation into an Ecore model
 1. Editor - provides IDE features, e\.g\. auto-completion, syntax highlighting, etc.

 * '''Validation Rules:''' these rules will give warnings in the editor if they find find consistencies in the code

 1. ''checkUpdateGrammarConsistency:'' checks, if the grammar is an updated grammar, for consistencies between the originals and the new grammar e.g.: status: not migrated

 2. ''!!!!CheckReferencedOnlyOnce:'' this should warn if there is a rule that is only referenced once, this is an inlining hint e.g.: status: migrated

 3. ''checkPassthroughRule:'' !e.g.:this tests if a rule gets just passed through a ::= b b ::= "literal" <=> a ::= "literal" , which is better for EBNF

 4. ''checkEqualAlternative:'' this tests if a rule got equal alternatives e.g.: a::= d | d status: still some problems

 5. ''checkDuplicateRules:'' checks if there is another rule in the EtsiBnf, that got the same behaviour e.g.: a ::= "literal" | b c ::= "literal" | b status: migrated

 6. ''checkSubruleDuplicates:''

  status: not migrated

 7. ''check unused rule:'' it checks if a rule is used (exept for the rule with the number 1)

  status: migrated

 8. ''checkNameIsUnique:'' checks if the nam of a rule is already in use e.g.: a ::= "end" a ::= "fin"

  status: migrated

 * '''Generation:'''

  -basic generation has been achieved but the output-format is unclear. Works with a Xtend-generator, momentary "xmi-like" output for a bnf grammar      -old version had: mwe2 Generator and Xpand2 support

 * it could generate mergeGrammars from !CoreGrammars and !CompositeGrammars from Merge grammars -seemingly it could produce a xsl-fo-file with the corresponding nodemodel

  -new version: xsl-fo file for all bnf grammars (not for merge or deltagrammars) this can be Rendered to Pdf using apache-fop

 * '''Formatting:'''

  ''    old:''            had some but they are got commented out in the main project

  ''    new:''           Line-break after every rule, white-spaces after all literals,  possible update linebreak and double tab after all >|< bars

 * '''Refactoring & Quickfixing:'''

 1. ''auto Numbering of rules'' -not migrated
 1. ''remove unused rules'' -migrated

  1.''     replacement of passthroughRules ''    -not migrated

 1. ''refactor uppercasetokenRules '' -not migrated

  1.''    find references''    , this one is standard in xtext2.* -renaming, this is standard in xtext2.*

  *Grammar composition:

  -3 grammartypes:
    grammar: normal grammar deltagrammar:        different notation for a extension grammar,
      adds new rules to a grammar (regular rules)and  adds changes to rules of the extended grammar(extension rules) -can be automaticly created
    mergegrammar:        for merging extensions
  -old version had an automatic composition Process, for merge grammars, with a small pop-up-menu.

 * at the moment no support in the new version

 * '''Deploying:'''

  -export project: Plug-in Development/deployable plug-ins and fragments -rcp project with a minimal eclipse editor
