2009-07-29parser:Robert Griesemer5-176/+146
- Changed filter function for parser.ParsePackage to take an *os.Dir instead of a filename for more powerful filters - Removed TODO in ast.PackageInterface: Now collect package comments from all package files - Cleanups in godoc: Use the new ParsePackage and PackageInterface functions; as a result computing package information is much simpler now.

2009-07-29Flatten the Frame tree. Now each function call produces aAustin Clements8-206/+218
single frame and non-overlapping variables reuse frame slots. As a result, entering and exiting blocks no longer requires code execution, which means jumps across block boundaries should be doable now. Frame slot initialization happens at definition time now, instead of at frame creation time. As an added bonus, Scope's are now exclusively compile-time objects and we no longer need to specially track the function activation frame for access to out vars.

2009-07-28make every func literal expression allocate,Russ Cox4-129/+138
so that == on func means that the functions originated in the same execution of a func literal or definition. before, there was an inconsistency: func() {x++} != func() {x++} but func() {} == func() {} this CL makes the second case != too, just like make(map[int]int) != make(map[int]int) R=r DELTA=202 (71 added, 62 deleted, 69 changed) OCL=32393 CL=32398

2009-07-28Intersperse comments nicely when printing an AST.Robert Griesemer12-190/+359
gofmt formatted source code looks pretty good already; with a bit more fine-tuning it should be great. printer.go: - Implemented comment intersperse algorithm. The approach is a result of many trial-and-error experiments but at this point reasonably simple and open to arbitrary fine-tuning. parser.go: - Simplified handling of lead and line comments (formerly called leading and trailing comments). - Use a comments list instead of an array (I may change this back - this is not obviously better and uses more space). doc.go: - Remove comments from AST nodes that have been 'consumed' in the documentation to avoid duplicate printing of them. Allows for better control of what is printed w/o use of printing control flags (which are hard to use and not fine-grained enough). Corresponding adjustments to various clients of these files.

2009-07-28Ring ADT.Robert Griesemer3-0/+495
- Provides analogous functionality to a doubly-linked list implementation. - Completely symmetric set of operations. - Operations on the ADT do not lead to results that are outside the domain of the ADT (closed interface). - Alternative to container/list.

2009-07-28Implement if, for (modulo ranges), break, continue, increment,Austin Clements3-31/+322
and decrement. blockCompilers now form a tree the mimics the nesting of scopes and provide convenient ways to enter and exit scopes. blockCompilers also track the break and continue PC for the current block. The statement testing interface now works in lists of statements, which simplifies a bunch of things. R=rsc APPROVED=rsc DELTA=401 (335 added, 44 deleted, 22 changed) OCL=32308 CL=32317
