2012-01-19Handle predicates that recurse in a check() expressionTim Chevalier-9/+10
typestate was using the enclosing function ID for the "this function returns" constraint, which meant confusion and panic in the case where a predicate p includes "check p()". Fixed it to use a fresh ID. Closes #933
2012-01-19rustc: ";" to "," in enumsPatrick Walton-11/+11
2012-01-19rustc: Remove trailing whitespacePatrick Walton-1/+1
2012-01-19Compute typestates for FRU exprs correctly, plus a bit of cleanupTim Chevalier-50/+36
The code in Issue 948 was causing typestate to diverge because it was using the prestate for the whole expression -- not the post- state for the fields list -- as the prestate for the record base expression. Fixed. Closes #948
2012-01-19rustc: "tag" -> "enum"Patrick Walton-5/+5
2012-01-18Remove '.' after nullary tags in patternsTim Chevalier-77/+77
Does what it says on the tin. The next commit will remove support for this syntax.
2012-01-17Allow omission of the '.' after nullary tag patternsTim Chevalier-43/+52
This commit allows patterns like: alt x { some(_) { ... } none { } } without the '.' after none. The parser suspends judgment about whether a bare ident is a tag or a new bound variable; instead, the resolver disambiguates. This means that any code after resolution that pattern-matches on patterns needs to call pat_util::normalize_pat, which consults an environment to do this disambiguation. In addition, local variables are no longer allowed to shadow tag names, so this required changing some code (e.g. renaming variables named "mut", and renaming ast::sub to subtract). The parser currently accepts patterns with and without the '.'. Once the compiler and libraries are changed, it will no longer accept the '.'.
2012-01-13deprecate fn exprs and the fn() type, preferring fn@ and native fnNiko Matsakis-4/+5
2012-01-13Obj system? What obj system?Marijn Haverbeke-16/+0
Removes the obj system from the compiler. Closes #1484
2012-01-12Make driver::session::session no longer an objectMarijn Haverbeke-4/+10
Rather, it is now a struct where properties like opts are accessed directly, and the error-reporting methods are part of a static impl (with the same name as the type).
2012-01-11Implement std::map as an iface/impl instead of an objMarijn Haverbeke-5/+5
2012-01-09Remove proto_sugar and 'lambda' as keyword, commit to fn@.Graydon Hoare-1/+1
2012-01-06Disallow variable names that shadow tags in scopeTim Chevalier-6/+6
Now, if you have a tag named "foo", a variable declaration like "let foo..." is illegal. This change makes it possible to eliminate the '.' after a nullary tag pattern in an alt (but I'll be doing that in a future commit) -- as now it's always obvious whether a name refers to a tag or a new declared variable. resolve implements this change -- all the other changes are just to get rid of existing code that declares variables that shadow tag names.

this will address the (crashing) new test added.

2011-12-23Parse `iface` items and interface references in `impl` items.Marijn Haverbeke-3/+2
The (temporary) syntax is iface seq<T> { fn len() -> uint; fn iter(f: block(T)); } // The 'blah<T>' can be left of to default the name of the // impl to seq<T>. The 'of seq<T>' can be left off when // not implementing a named interface. impl blah<T> of seq<T> for [T] { fn len() -> uint { vec::len(self) } fn iter(f: block(T)) { for x in self { f(x); } } }

2011-12-19Add type argument field to expr_pathMarijn Haverbeke-2/+2
This way, you can explicitly provide type parameters when calling a generic method. Issue #1227

2011-12-16Make uses of self in impls compileMarijn Haverbeke-2/+0
Get rid of expr_self_call, introduces def_self. `self` is now, syntactically, simply a variable. A method implicitly brings a `self` binding into scope. Issue #1227

2011-12-08Allow binding of nested patternsMarijn Haverbeke-14/+6
See src/test/run-pass/nested-patterns.rs for some examples. The syntax is boundvar@subpattern Which will match the subpattern as usual, but also bind boundvar to the whole matched value. Closes #838

2011-10-21Change the way block calls are parsed, mark them as block-calls.Marijn Haverbeke-4/+4
This makes it possible to omit the semicolon after the block, and will cause the pretty-printer to properly print such calls (if pretty-printing of blocks wasn't so broken). Block calls (with the block outside of the parentheses) can now only occur at statement level, and their value can not be used. When calling a block-style function that returns a useful value, the block must be put insde the parentheses. Issue #1054
