rontana / yaxx Goto Github PK

What steps will reproduce the problem?
1. not every non-terminal need to be represented as an XML element
2. record only the non-terminals that are reduced with a non-empty action, 
   such that the resulting parse tree is an Abstract Syntax Tree
3. it is yet to know whether the DTD for such AST can be derived

What is the expected output? What do you see instead?
Abstract Syntax Tree. Parsing Tree.

ast

I know this is not an issue, but didn't find any place to add enhancement.
Currently a XML node is about the type of the token and an id, that would
be really interesting (I guess) if we could have also the line number...

I'm thinking of working with yaxx and php, but I need to do multi-passes
operations, so the line number would definitely help me to track the nodes

Attachments:
- source code of the package I compiled (0.1.4)
- compiled library

What steps will reproduce the problem?
1. yaxx works for many yacc grammars, with similar project structure and
   Makefile, which can be cloned from an existing template project such as
   "ansic" 
2. preparing such a template is quite tedious and requires some basic
understanding of writing a Makefile.
3.

What is the expected output? What do you see instead?

It would be nice to have a more streamlined command such
   that the command line is as simple as

   yaxx-proc <scan.l> <grammar.y> <program>

   which will invoke lex/yacc and yaxx generated parser on the program.

   Even better if there is a repository of grammars that can be fetched
   on demand to generate the parser without any hassle.

 -- William Candillon proposed the above feature enhancement.

What steps will reproduce the problem?
1. bison 2.2 is marked stable in gentoo
2. the yaxx template is already updated for bison 2.1
3.

What is the expected output? What do you see instead?
bison/data/yaxx-0.12-bison-2.2.c 
bison/data/yaxx-0.12-bison-2.1.c

Please use labels and text to provide additional information.
compatibility bison update

What steps will reproduce the problem?
1. the history information is not migrated
2. cvs2svn broke when an error "Unexpected record ..." hinders the
   migration of the complete cvs repository from sourceforge
3. therefore i could only move the head version over to the svn repository

What is the expected output? What do you see instead?
history of the repository changes before the importation. missing. 

Please use labels and text to provide additional information.
repository, migration

What steps will reproduce the problem?
1. the mother project bison is already in gentoo portage tree
2. yaxx is simply a template file (e.g. yaxx-0.12-bison-2.1.c) to be add to
 the bison:  /usr/share/bison/
3. it is useful to install yaxx using a single command in gentoo "emerge yaxx" 

What is the expected output? What do you see instead?
"emerge yaxx" to install every depended packages, including bison. 
no there yet.

Please use labels and text to provide additional information.
gentoo emerge ebuild

In the short term futur, yaxx should be able to output not only xml format
but also JSON, E4X, Graphviz and others.
