From 2148bdfcc7ea7b9614d8cbe596cbe7bb75b57cd1 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Mon, 3 Oct 2016 09:49:39 -0700 Subject: rustc: Rename rustc_macro to proc_macro This commit blanket renames the `rustc_macro` infrastructure to `proc_macro`, which reflects the general consensus of #35900. A follow up PR to Cargo will be required to purge the `rustc-macro` name as well. --- src/libproc_macro_plugin/parse.rs | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 src/libproc_macro_plugin/parse.rs (limited to 'src/libproc_macro_plugin/parse.rs') diff --git a/src/libproc_macro_plugin/parse.rs b/src/libproc_macro_plugin/parse.rs new file mode 100644 index 00000000000..9af8a68cdcf --- /dev/null +++ b/src/libproc_macro_plugin/parse.rs @@ -0,0 +1,26 @@ +// Copyright 2016 The Rust Project Developers.
