Work towards a non-panicing parser (libsyntax)

2015-04-05T08:52:50+00:00

- Functions in parser.rs return PResult<> rather than panicing - Other functions in libsyntax call panic! explicitly for now if they rely on panicing behaviour. - 'panictry!' macro added as scaffolding while converting panicing functions. (This does the same as 'unwrap()' but is easier to grep for and turn into try!()) - Leaves panicing wrappers for the following functions so that the quote_* macros behave the same: - parse_expr, parse_item, parse_pat, parse_arm, parse_ty, parse_stmt

Replace MacExpr / MacPat / MacItems with MacEager

2015-02-27T19:17:05+00:00

MacEager is a MacResult implementation for the common case where you've already built each form of AST that you might return. Fixes #17637. Based on #18814. This is a [breaking-change] for syntax extensions: * MacExpr::new becomes MacEager::expr. * MacPat::new becomes MacEager::pat. * MacItems::new becomes MacEager::items. It takes a SmallVector directly, not an iterator.

cleanup: replace `as[_mut]_slice()` calls with deref coercions

Continue cfg syntax transition

2014-10-12T18:40:19+00:00

All deprecation warnings have been converted to errors. This includes the warning for multiple cfgs on one item. We'll leave that as an error for some period of time to ensure that all uses are updated before the behavior changes from "or" to "and".

Turn on cfg format warnings

Convert cfg syntax to new system

2014-09-28T05:59:26+00:00

This removes the ability to use `foo(bar)` style cfgs. Switch them to `foo_bar` or `foo="bar"` instead. [breaking-change]

syntax: fix fallout from using ptr::P.
