2016-07-14syntax_ext: format: allow multiple formats for one argumentWang Xuerui-69/+57
This commit removed the restriction of only allowing one type per argument. This is achieved by adding mappings between macro arguments and format placeholders, then taking the mapping into consideration when emitting the Arguments expression. syntax_ext: format: fix implicit positional arguments syntax_ext: format: don't panic if no args given for implicit positional args Check the list lengths before use. Fixes regression of `compile-fail/macro-backtrace-println.rs`. syntax_ext: format: also map CountIsParam indices to expanded args syntax_ext: format: fix ICE in case of malformed format args
2016-07-14syntax_ext: format: rename variants of ArgumentType for clarityWang Xuerui-7/+7
2016-07-14syntax_ext: format: resolve named arguments earlyWang Xuerui-85/+62
Converts named argument references into indices, right after verification as suggested by @alexcrichton. This drastically simplifies the whole process!
2016-07-14syntax_ext: format: separate verification and translation of piecesWang Xuerui-5/+11
2016-07-14format: remove all implicit ref handling outside of libfmt_macrosWang Xuerui-17/+12
format: beautifully get rid of ArgumentNext and CountIsNextParam Now that CountIsNextParam and ArgumentNext are resolved during parse, the need for handling them outside of libfmt_macros is obviated. Note: *one* instance of implicit reference handling still remains, and that's for implementing `all_args_simple`. It's trivial enough though, so in this case it may be tolerable.
2016-07-06Correct inline assembly clobber formatting.CensoredUsername-0/+3
Fixes the formatting for inline assembly clobbers used in the book. As this causes llvm to silently ignore the clobber an error is also added to catch cases in which the wrong formatting was used. Additionally a test case is added to confirm that this error works.
2016-07-03prefer `if let` to match with `None => {}` arm in some placesZack M. Davis-29/+17
This is a spiritual succesor to #34268/8531d581, in which we replaced a number of matches of None to the unit value with `if let` conditionals where it was judged that this made for clearer/simpler code (as would be recommended by Manishearth/rust-clippy's `single_match` lint). The same rationale applies to matches of None to the empty block.
2016-06-29Disallow `derive` on items with type macrosJeffrey Seyfried-4/+14
2016-06-26Rollup merge of #34436 - jseyfried:no_block_expr, r=eddybJeffrey Seyfried-16/+14
To allow these braced macro invocation, this PR removes the optional expression from `ast::Block` and instead uses a `StmtKind::Expr` at the end of the statement list. Currently, braced macro invocations in blocks can expand into statements (and items) except when they are last in a block, in which case they can only expand into expressions. For example, ```rust macro_rules! make_stmt { () => { let x = 0; } } fn f() { make_stmt! {} //< This is OK... let x = 0; //< ... unless this line is commented out. } ``` Fixes #34418.
2016-06-26Rollup merge of #34339 - jseyfried:thin_vec, r=petrochenkov,ManishearthJeffrey Seyfried-3/+3
Generalize and abstract `ThinAttributes` to `ThinVec<Attribute>`.
2016-06-26Rollup merge of #34316 - jseyfried:refactor_ast_stmt, r=eddybJeffrey Seyfried-8/+11
Refactor away `ast::Decl`, refactor `ast::Stmt`, and rename `ast::ExprKind::Again` to `ast::ExprKind::Continue`.
2016-06-26Rollup merge of #33943 - jseyfried:libsyntax_cleanup, r=nrcJeffrey Seyfried-2/+2
Miscellaneous low priority cleanup in `libsyntax`.
2016-06-26Rollup merge of #34385 - cgswords:tstream, r=nrcJeffrey Seyfried-14/+19
syntax-[breaking-change] cc #31645 (Only breaking because ast::TokenTree is now tokenstream::TokenTree.) This pull request refactors TokenTrees into their own file as src/libsyntax/tokenstream.rs, moving them out of src/libsyntax/ast.rs, in order to prepare for an accompanying TokenStream implementation (per RFC 1566).

A lot of the refactors, however, seem helpful, so leave those in, particularly since we may want to make this change in the future.

syntax_ext: format: nest_level's are no more Just noticed this while working on #33642 and here's a quick fix, shouldn't touch anything else. It's some historic code indeed...
