Add a syntax extension to log syntax, for debugging macros. 2011-08-08 21:17:33 +00:00			`import base::*;`

Major clean-up of std::io Use ifaces instead of objs, stop wrapping everything in two (or three) layers of no-value-added indirection, and remove some of the more pointless/outdated idioms from the code. 2012-01-11 14:15:54 +00:00			`import std::io::writer_util;`

Reformat for new mode syntax, step 1 Long lines were fixed in a very crude way, as I'll be following up with another reformat in a bit. 2011-09-12 09:27:30 +00:00			`fn expand_syntax_ext(cx: ext_ctxt, sp: codemap::span, arg: @ast::expr,`
Change the type for the macro body to also store the span. Note: the body is the part of the macro syntax between the {}. 2012-02-01 03:30:26 +00:00			`_body: ast::mac_body) -> @ast::expr {`

Reformat This changes the indexing syntax from .() to [], the vector syntax from ~[] to [] and the extension syntax from #fmt() to #fmt[] 2011-08-19 22:16:48 +00:00			`ret @{id: cx.next_id(), node: ast::expr_rec([], option::none), span: sp};`
Port the compiler to the typaram foo<T> syntax. 2011-08-12 14:15:18 +00:00			`}`
