From d7efd7639420f4c840cbfdfcbbb3c45292f3ac54 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Mon, 16 Oct 2006 15:55:34 +0000 Subject: * Big cleanup of the semantics of paths, strings, contexts, string concatenation and string coercion. This was a big mess (see e.g. NIX-67). Contexts are now folded into strings, so that they don't cause evaluation errors when they're not expected. The semantics of paths has been clarified (see nixexpr-ast.def). toString() and coerceToString() have been merged. Semantic change: paths are now copied to the store when they're in a concatenation (and in most other situations - that's the formalisation of the meaning of a path). So "foo " + ./bla evaluates to "foo /nix/store/hash...-bla", not "foo /path/to/current-dir/bla". This prevents accidental impurities, and is more consistent with the treatment of derivation outputs, e.g., `"foo " + bla' where `bla' is a derivation. (Here `bla' would be replaced by the output path of `bla'.) --- src/libexpr/lexer.l | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libexpr/lexer.l') diff --git a/src/libexpr/lexer.l b/src/libexpr/lexer.l index df30a5ed07..9f0f0b335f 100644 --- a/src/libexpr/lexer.l +++ b/src/libexpr/lexer.l @@ -64,7 +64,7 @@ static Expr unescapeStr(const char * s) } else t += c; } - return makeStr(toATerm(t)); + return makeStr(toATerm(t), ATempty); } -- cgit 1.4.1
