- commented public interface
- much better and very precise error messages
- much better tracing output
- many more checks (still permits more than just syntactically legal
programs, but much more is checked that can be checked w/o semantic information)
- updated with respect to updated AST
- general cleanup throughout
Parser almost ready for move into lib/go.

- by moving Position into token, scanner dependencies
are removed from several files
- clearer field names in token.Position, now possible to
have a Pos() accessor w/o naming conflicts
- added Pos() accessor
- use anonymous token.Position field in AST nodes

- use explicit expression lists instead of binary trees to represent lists of the form a, b, c
(per discussion w/ Russ)
- use explicit nodes for various language constructs for better readability
- various adjustments in parsing and printing
next steps:
- clean up AST fully so it can be checked in as library

- various parser fixes to match updated spec (&&, &^=, label decls, const decls)
- using html template for directory and error page in doc server
- show compile errors inplace in the source
- cleanups

- correctly associate comments with declarations
(available through AST)
- very raw printing of interface
- much more functionality, now needs some formatting, sorting, etc.

if T has pointer methods. this is just a heuristic
but it catches the problem robert ran into and
lets me put the larger interface issues aside for
now. found one bug in pretty.
R=ken
OCL=26141

- removed any symbol table stuff
- some interface cleanup
- removed lot's of dead wood
- half the support for type switches (simple form)
- name capitalization
Several rounds to come.

- move scanner to into lib/lang
- added test
- adjusted various make and build files

- separated out token definition from scanner
- cleaned up token and scanner implementation
- added comments to exported interfaces

- require ()'s around composite literals at the if/for/switch control clause level
- fixed a nasty bug: passing a value instead of a pointer to a value to an interface
variable - and not noticing that the value is copied
R=r
OCL=25649

- removed unneeded code that accumulated over time
- change src from string to []byte (perhaps should be io.Read
but that has some other disadvantages)
- simplified interface
R=r
OCL=25615
CL=25615
- converted more of AST and parser to use interfaces and explicit
structs for individual Go constructs (can be replaced now with
interface calls such that the parser becomes AST structure
independent, as suggested by rsc)
- added more tests (find all .go files under GOROOT)
- (temporarily) lost html links for identifiers when generating
html output
- TODO: lots of cleanups
R=r
OCL=25518
CL=25518
- moved Object, Type, Scope out of AST into symboltable
- moved universe into symboltable
- removed dead code
- fixed dependency computation (pretty -d filename.go)
- lots of cleanups
- removed tocken channel connection between parser and scanner
(was cute, but not really needed)

using interfaces properly => much cleaner code
- converted tracing code to use 'defer' statement
- next steps: convert rest of ast as well
R=r
OCL=24277
CL=24277
- fine-tuning of ast
- more accurate block pos info (improved printing in some cases)
- collecting local variables and fields
- more work on type checking
- lots of minor tweaks
