2009-01-16- language for export via capitalized identifiersRobert Griesemer1-118/+62
- removed explicit "export" declarations and keyword - fixed a few glitches and adjusted examples (The details of what "export" mean should be clarified in the spec, this is just so we have a working doc for now.) R=r DELTA=131 (7 added, 63 deleted, 61 changed) OCL=22753 CL=22970

2009-01-06- documenting old "new()"Robert Griesemer1-61/+99
- adding "init()" - fixing some bugs with slice documentation DELTA=118 (45 added, 7 deleted, 66 changed) OCL=22084 CL=22136
2009-01-05A first attempt to capture the type changes.Robert Griesemer1-259/+250
Instead of trying to make open arrays look like arrays (which they aren't, they just look like them), I decided to call them "slice types". As a result they have value semantics, and one can really talk about what they really are. Note: - There are lots of missing details - There are probably lots of mistakes Looking for some initial feedback. R=r DELTA=444 (180 added, 189 deleted, 75 changed) OCL=21769 CL=22020

2008-12-17- ripped out excessively fancy way of describing grammarRobert Griesemer1-41/+26
in favor of explicit constructs - simpler, clearer, and shorter overall - no spec changes (in retrospect it was just a (my) mistake to put it in in the first place) R=r DELTA=55 (13 added, 28 deleted, 14 changed) OCL=21434 CL=21462
2008-12-16- Add introduction section (1 page), essentially a condensed formRobert Griesemer1-232/+152

2008-11-07- language to define type equality rigorouslyRobert Griesemer1-75/+201

2008-11-04- added (incomplete) section on parameter passingRobert Griesemer1-1/+70

2008-10-30- clarified section on numeric types: platform-dependent typesRobert Griesemer1-42/+45
are different from platform-independent types (not just aliases), except for byte, uint8 - added missing documentation of new(a, len, cap) - updated todo/issues lists DELTA=70 (24 added, 21 deleted, 25 changed) OCL=17920 CL=18174
2008-10-24Preparation for varargs: Proposal for syntax.Robert Griesemer1-4/+11

2008-10-23- clarified that composites are values created every time theyRobert Griesemer1-2/+4
are evaluated, removed corresponding TODO. R=r DELTA=5 (3 added, 1 deleted, 1 changed) OCL=17746 CL=17751
2008-10-23First cut at incorporating anonymous fields of pointer types into theRobert Griesemer1-27/+81
spec. I have deliberately removed the wording about receivers where it was before because I think it needs to be more precise. There is a TODO. DELTA=90 (54 added, 0 deleted, 36 changed) OCL=17597 CL=17716
2008-10-20- be even more explicit about ideal number conversion in expressionsRobert Griesemer1-8/+12

(seems not controversial) R=r DELTA=8 (3 added, 2 deleted, 3 changed) OCL=16940 CL=16940
2008-10-10- Fixed bug in spec: PrimaryExpr is too restrictive in most placesRobert Griesemer1-28/+57
(for instance *p was not allowed on the left side of "="). Changed to Expression everywhere (this is too liberal, UnaryExpr is probably good enough, but it seems funny, and we need to check semantically anyway). This matches 6g yacc. - Write expression syntac recursively to express evaluation order and precedence syntactically. - Organized open issues list, folded in stuff from todo.txt which is now obsolete. R=r DELTA=108 (41 added, 52 deleted, 15 changed) OCL=16903 CL=16910
2008-10-09- added missing case for opt. semicolons (labels)Robert Griesemer1-5/+15

2008-10-08- make optional semicolons explicit in grammar in all placesRobert Griesemer1-51/+53
except in statement list, where it is expressed in words - allow for empty import, const, type, and var decl lists inside ()'s - fixed grammar for inc/dec statements - added empty statement as it appears to be accepted by 6g R=r DELTA=75 (23 added, 21 deleted, 31 changed) OCL=16785 CL=16785
2008-10-07- precise scope rulesRobert Griesemer1-109/+189
