wingo pushed a commit to branch main in repository guile. commit 9e0f03c5fd36764827c8bb03887f14640c883b70 Author: Andy Wingo <wi...@pobox.com> AuthorDate: Tue Feb 20 13:36:14 2024 +0100
Macro-introduced top-level vars scope to their module even if unbound * module/ice-9/psyntax.scm (analyze-variable): Previously, a reference to a top-level variable in a module other than the current module would be silently rewritten to reference the current module, if the variable was unbound in its original module. This was a hack from the early days of when we extended psyntax to know about the module system. Fix to properly use the scope of the introduced binding instead of the scope of the macro use site. * test-suite/tests/syntax.test ("macro-introduced cross-module unbound identifiers"): Add test. * module/ice-9/psyntax-pp.scm: Regenerate. --- module/ice-9/psyntax-pp.scm | 92 +++++++++++++++++++++----------------------- module/ice-9/psyntax.scm | 10 ++--- test-suite/tests/syntax.test | 12 ++++++ 3 files changed, 58 insertions(+), 56 deletions(-) diff --git a/module/ice-9/psyntax-pp.scm b/module/ice-9/psyntax-pp.scm index 58c9c403a..bd90b37b4 100644 --- a/module/ice-9/psyntax-pp.scm +++ b/module/ice-9/psyntax-pp.scm @@ -80,14 +80,9 @@ (let ((key kind)) (cond ((memv key '(public)) (modref-cont mod var #t)) -
