2011-04-14Work on destructors, not entirely functional yet (no tydesc integration).Graydon Hoare-4/+22
2011-04-13Add support for upper-case hex and binary output to #fmt.Brian Anderson-0/+3
Only works for uints at present. Necessitated the addition of _str.to_upper.
2011-04-13Add more commentary about ExtFmtBrian Anderson-14/+7
2011-04-13Add support for printing uints as lower-case hex to ExtFmt.Brian Anderson-13/+78
Begin passing an ExtFmt.RT.conv parsed format description to each of the ExtFmt.RT.conv* functions.
2011-04-13Move #fmt conversion model into ExtFmt.CT namespaceBrian Anderson-29/+28
2011-04-13Lex numeric escapes, needed for lib-str.rs (which now passes).Graydon Hoare-13/+77
2011-04-12typestate_check can now handle expr_block, expr_if, and expr_binaryTim Chevalier-2/+3
(caveat for the latter: it assumes that binary operations are strict; a TODO is to detect or and and and correctly reflect that they're lazy in the second argument). I had to add an ann field to ast.block, resulting in the usual boilerplate changes. Test cases that currently work (if you uncomment the typestate pass in the driver) (all these are under test/compile-fail): fru-typestate ret-uninit use-uninit use-uninit-2 use-uninit-3
2011-04-12rustc: Switch to indices for type parametersPatrick Walton-18/+16
2011-04-12Further work on typestate. Handles expr_rec and expr_assign now.Tim Chevalier-9/+13
Also changed the ts_ann field on statements to be an ann instead, which explains most of the changes. As well, got rid of the "warning: no type for expression" error by filling in annotations for local decls in typeck (not sure whether this was my fault or not). Finally, in bitv, added a clone() function to copy a bit vector, and fixed is_true, is_false, and to_str to not be nonsense.
2011-04-11Factor out creation of calls into ExtFmt.RTBrian Anderson-12/+12

2011-04-11Move extfmt parsing into standard libraryBrian Anderson-210/+1
2011-04-11Move the extfmt data model into the standard library.Brian Anderson-48/+30
2011-04-09Fix codemap.lookup_posMarijn Haverbeke-15/+12
Previously, it would place every single location in the first file of the crate that was parsed.
2011-04-09Move to single-uint file-position representation.Marijn Haverbeke-319/+374
This makes passing them around cheaper. There is now a table (see front/codemap.rs) that is needed to transform such an uint into an actual filename/line/col location. Also cleans up the span building in the parser a bit.
2011-04-09Make lexer buffer the whole fileMarijn Haverbeke-59/+66
This way, it won't have to go through a bunch of calls for each byte fetched.
2011-04-07Support for self-calls that take arguments.Lindsey Kuper-4/+11
Nicer parsing of self-calls (expr_self_method nodes inside expr_call nodes, rather than a separate expr_call_self) makes typechecking tractable. We can now write self-calls that take arguments and return values (see: test/run-pass/obj-self-*.rs).
2011-04-07Add a very basic crate-dump utilityMarijn Haverbeke-0/+66
'rustc -ls [cratelib]' will now dump out a list of symbols defined by the crate, as well as a short description of what they are.
2011-04-07Revise EBML reader APIMarijn Haverbeke-191/+122
New one is less stateful, easier to work with.
2011-04-06Continued sketching out code for checking states against preconditions.Tim Chevalier-10/+11
It's still sketchy. I added a typestate annotation field to statements tagged stmt_decl or stmt_expr, because a stmt_decl statement has a typestate that's different from that of its child node. This necessitated trivial changes to a bunch of other files all over to the compiler. I also added a few small standard library functions, some of which I didn't actually end up using but which I thought might be useful anyway.
2011-04-05Last pieces of self-call support.Lindsey Kuper-1/+1
The last few pieces of the hack that lets us use trans.trans_call() to translate self-calls, plus a fix for the parser buy that was preventing self-call expressions from getting past parsing. test/run-pass/obj-self.rs works now (as in it actually prints "hi!" twice!).
2011-04-05Further on the path toward self-awareness.Lindsey Kuper-2/+6
Mostly: * Merciless refactoring of trans.rs so that trans_call can work for self-calls as well as other kinds of calls Also: * Various changes to go with having idents, rather than exprs, in expr_call_self AST nodes * Added missing case for SELF token to token.to_str()
2011-04-04Make box prefix operator and box type carry mutability flag.Graydon Hoare-3/+7
2011-04-01Support for passing native types through metadata/creader.Graydon Hoare-0/+2
2011-04-01rustc: Get tag variants from the crate metadataPatrick Walton-6/+49
2011-04-01Started adding support for typestate checking.Tim Chevalier-28/+31
I added a new field to the ast "ann" type for typestate information. Currently, the field contains a record of a precondition bit vector and postcondition vector, but I tried to structure things so as to make it easy to change the representation of the typestate annotation type. I also had to add annotations to some syntactic forms that didn't have them before (fail, ret, be...), with all the boilerplate changes that that would imply. The main call to the typestate_check entry point is commented out and the actual pre-postcondition algorithm only has a few cases implemented, though the overall AST traversal is there. The rest of the typestate algorithm isn't implemented yet.

The patch also includes a number of smaller fixes to the pretty-printer that were encountered on the way.
