From 1ecc97b6bdb27e56d832ca48cdafd3dbb5185a04 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Sat, 6 Aug 2011 16:05:24 +0000 Subject: * Add a Nix expression search path feature. Paths between angle brackets, e.g. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit import are resolved by looking them up relative to the elements listed in the search path. This allows us to get rid of hacks like import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib" The search path can be specified through the ‘-I’ command-line flag and through the colon-separated ‘NIX_PATH’ environment variable, e.g., $ nix-build -I /etc/nixos ... If a file is not found in the search path, an error message is lazily thrown. --- src/libexpr/common-opts.hh | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/libexpr/common-opts.hh') diff --git a/src/libexpr/common-opts.hh b/src/libexpr/common-opts.hh index 80298ce55d1b..6b7247fc3d89 100644 --- a/src/libexpr/common-opts.hh +++ b/src/libexpr/common-opts.hh @@ -11,6 +11,9 @@ bool parseOptionArg(const string & arg, Strings::iterator & i, const Strings::iterator & argsEnd, EvalState & state, Bindings & autoArgs); +bool parseSearchPathArg(const string & arg, Strings::iterator & i, + const Strings::iterator & argsEnd, EvalState & state); + } -- cgit 1.4.1
