Jim Porter e63ef66c57 Add support for the "splice operator" in Eshell ... This allows splicing lists in-place in argument lists, which is particularly important when defining aliases using the '$*' special variable (bug#59960). * lisp/eshell/esh-var.el (eshell-parse-variable): Add support for the splice operator. (eshell-interpolate-variable): Let 'eshell-parse-variable' handle adding 'eshell-escape-arg'. (eshell-complete-variable-reference): Handle the splice operator. * lisp/eshell/esh-arg.el (eshell-concat-groups) (eshell-prepare-splice): New functions... (eshell-resolve-current-argument): ... use them. (eshell-splice-args): New function. * lisp/eshell/esh-cmd.el (eshell-rewrite-named-command): Handle 'eshell-splice-args'. * lisp/eshell/esh-util.el (eshell-list-to-string): New function... (eshell-flatten-and-stringify): ... use it. * lisp/eshell/em-cmpl.el (eshell-complete-parse-arguments): Remove 'eshell-splice-args' sigils in Eshell command forms so that we can perform completion on splice-expansions. * lisp/eshell/em-unix.el (eshell-complete-host-reference): Don't try to complete arguments containing "$@". * test/lisp/eshell/esh-var-tets.el (esh-var-test/interp-list-var) (esh-var-test/interp-list-var-concat, esh-var-test/interp-var-splice) (esh-var-test/interp-var-splice-concat) (esh-var-test/quoted-interp-list-var) (esh-var-test/quoted-interp-list-var-concat) (esh-var-test/quoted-interp-var-splice) (esh-var-test/quoted-interp-var-splice-concat): New tests. * test/lisp/eshell/em-alias-tests.el (em-alias-test/alias-all-args-var-splice): New test. * doc/misc/eshell.texi (Dollars Expansion): Explain the splice operator. (Aliases): Expand documentation and use '$@*'. (Built-ins, Bugs and Ideas): Use '$@*' where appropriate. * etc/NEWS: Announce this change.		2022-12-15 21:41:03 -08:00
