From 8a10360c912bc344ea9ce7f8871a47a6e036552f Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Thu, 25 Mar 2010 12:19:41 +0000 Subject: * Simplify @-patterns: only `{attrs}@name' or `name@{attrs}' are now allowed. So `name1@name2', `{attrs1}@{attrs2}' and so on are now no longer legal. This is no big loss because they were not useful anyway. This also changes the output of builtins.toXML for @-patterns slightly. --- src/libexpr/nixexpr-ast.def | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/libexpr/nixexpr-ast.def') diff --git a/src/libexpr/nixexpr-ast.def b/src/libexpr/nixexpr-ast.def index 00b5f5a13716..2bf8492dd05e 100644 --- a/src/libexpr/nixexpr-ast.def +++ b/src/libexpr/nixexpr-ast.def @@ -77,8 +77,7 @@ Inherit | Expr ATermList Pos | ATerm | Scope | | Expr | VarPat | string | Pattern | -AttrsPat | ATermList ATermBool | Pattern | # bool = `...' -AtPat | Pattern Pattern | Pattern | +AttrsPat | ATermList ATermBool string | Pattern | # bool = `...'
