From 4f63afc1177021d6345502892dbd028f5d6db5eb Mon Sep 17 00:00:00 2001 From: Boris Kolpackov Date: Mon, 16 Jul 2018 15:21:26 +0200 Subject: Implement in module Given test.in containing something along these lines: foo = $foo$ Now we can do: using in file{test}: in{test.in} file{test}: foo = FOO The alternative variable substitution symbol can be specified with the in.symbol variable and lax (instead of the default strict) mode with in.substitution. For example: file{test}: in.symbol = '@' file{test}: in.substitution = lax --- build2/target.hxx | 27 --------------------------- 1 file changed, 27 deletions(-) (limited to 'build2/target.hxx') diff --git a/build2/target.hxx b/build2/target.hxx index 515a082..aad5331 100644 --- a/build2/target.hxx +++ b/build2/target.hxx @@ -1607,33 +1607,6 @@ namespace build2 virtual const target_type& dynamic_type () const {return static_type;} }; - // This is the venerable .in ("input") file that needs some kind of - // preprocessing. - // - // One interesting aspect of this target type is that the prerequisite - // search is target-dependent.
