- adjustments to match new ast/parser interface
- removed printer.go; functionality now in astprinter.go and docprinter.go
(more cleanups pending)
- enabled new doc printing in gds
(lots of fine tuning missing, but pieces falling into place; e.g. methods
associated with types. Consts, Vars, to come. Collection of all files
belonging to a package to come)

- separating printing of AST and documentation
- astprinter: will subsume ast printing functionality of printer
- docprinter: will subsume doc printing functionality of printer
also: more logic to collect all the documentation pertaining
to all files of a package
- parser: some cleanups, stricter syntax checks
- gds: hooks to test new doc printer (disabled)

- 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.

- 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

- 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

OCL=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

containing tabs
- snapshot of the day

but it's a large code base which compiles - will eventually go
away)

Preparations to track identifiers and declarations so that we can
generate good html links as pretty printer output:
- brought over old code and adjusted it
- initial hookups, nothing really running yet
R=r
OCL=21383
CL=21383
- fixed html tag generation
- simplified html escaping machinery
(not 100% correct for strings yet)
- can now produce the first mostly correct formatted html pages from source
with (fake) links: e.g. pretty -html srcfile.go > srcfile.html
R=r
OCL=20915
CL=20915
- first cut at html writer (will do html escaping, html tag production)
- first cut at generating basic html output via pretty
- some cleanups

- by default consider extra newlines in src for better formatting
- additional flags for control (-newlines, -maxnewlines, -optsemicolons)
- don't print ()'s around single anonymous result types
Status: Comparing the output of pretty with the input for larger files
shows mostly whitespace/formatting differences, which is what is desired.
TODO:
- Handling of overlong lines
- some esoteric cases which look funny
R=r
OCL=20293
CL=20293
- changed tab width to 8 chars by default to make test run properly
- excluded 4 files that are not idempotently printed
- fixed a couple of incorrect file position recordings in parser
- fine-tuned layout engine
- white-space formatting reasonable, but not perfect
- no handling of overlong lines
R=r
To use with smaller tabs: pretty -tabwidth=4 file.go
To use with blanks instead of tabs: pretty -usetabs=0 file.go
OCL=20184

- comment printing still disabled by default because idempotency test fails
- whitespace control better but not perfect yet
- snapshot before making some heuristics changes

for end of declarations, blocks, parameter lists, etc.
- use extra src positions to more accurately print comments
- fine-tuned low-level printing routine for comments
- added better debugging support
Status:
- comments now appear at the right place (inbetween the right tokens)
- newline control needs improvement (not very hard)
- comment printing disabled for now because pretty is not idempotent
with it; to enable: -comments
