2009-07-28Intersperse comments nicely when printing an AST.Robert Griesemer1-83/+224
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.

2009-07-09Show BUG comments in godoc:Robert Griesemer1-41/+53
ast.go: - rename Comments -> CommentGroup (less confusion) - change all comments/docs to be *CommentGroup filter.go: - do not remove unassociated comments from program as part of export filtering (they are needed by doc.go for BUG comments) scanner.go: - exclude '\n' from //-style comments parser.go: - rewrote collection of comments: now all collected comments are *ast.CommentGroups - clarified distinction between leading and trailing comments - fixed a bug in comment collection (parseGenDecl); corresponding test case is in printer/testdata - extra documentation doc.go: - collect BUG comments - corresponding fix for parser bug in comment collection comment.go: - simplified regex printer.go: - adjust comment printing to new representation printer_test.go, testdata/*: - enable printing of doc comments - extended tests package.html, package.txt: - added Bugs section gofmt: - enable printing of doc comments R=rsc DELTA=339 (126 added, 38 deleted, 175 changed) OCL=31403 CL=31416

2009-07-06- ast.FilterExports: strips all non-exported nodes from an ASTRobert Griesemer1-187/+76
- use FilterExports instead of the various predicates in printer.go and doc.go which simplifies a lot of code and makes it easier to deal with complex cases R=rsc DELTA=445 (197 added, 190 deleted, 58 changed) OCL=31110 CL=31196
