(seems not controversial) R=r DELTA=8 (3 added, 2 deleted, 3 changed) OCL=16940 CL=16940

R=r OCL=16938 CL=16938
2008-10-10- added missing ';' according to new rulesRobert Griesemer1-1/+1
(no effect on the test, but now parseable) R=r OCL=16936 CL=16936
2008-10-10until 6g implements it, warn about using int in interface.Russ Cox1-0/+4
R=ken OCL=16935 CL=16935
2008-10-10- implemented heuristic for composite literals starting with a type name:Robert Griesemer3-144/+116
if in a if, for, or switch header, must be parenthesized - implemented string concatenation - simplified a lot of code - added many more tests: can now parse all *.go files I got my hands on - printing output currently broken in some cases, use with -s (silent) option R=r OCL=16932 CL=16934

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

R=r OCL=16869 CL=16869
2008-10-09More spec progress:Robert Griesemer1-34/+98

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

type T struct { next *T } and type T *struct { next T } are valid without needing forward declarations. add "type T struct" syntax for forward struct declarations. add "type T interface" syntax, but commented out (need to fix semicolons first) R=ken DELTA=452 (259 added, 115 deleted, 78 changed) OCL=16580 CL=16584
