2021-05-15inferior: Support querying package replacements....I'm looking at this to help with adding support for looking up package replacements to store in the Guix Data Service. * guix/inferior.scm (inferior-package-replacement): New procedure. * tests/inferior.scm ("inferior-package-replacement"): New test. Christopher Baines
2021-04-29inferior: Make sure test refers to guile@3.0....* tests/inferior.scm ("inferior-package-inputs"): Compare with GUILE-3.0-LATEST since that's what 'lookup-inferior-packages' returns. Ludovic Courtès
2021-01-21repl: Fix exception handling for interpreted code....The 'stack' variable could be #f when code is interpreted, which in practice happens when running in "legacy" mode--i.e., when 'open-inferior' invokes "guile" instead of "guix repl". * guix/repl.scm (send-repl-response)[handle-exception]: Check whether STACK is true before passing it to 'stack->frames'. * tests/inferior.scm ("&inferior-exception, legacy mode"): New test. Ludovic Courtès
2021-01-21inferior: Add 'inferior-eval-with-store' tests....* tests/inferior.scm ("inferior-eval-with-store, exception") ("inferior-eval-with-store, not a procedure"): New tests. Ludovic Courtès
