In + > previous versions of the shell, this caused two functions "noglob" and + > "foo" to be defined. Any expansion of an alias in a function + > definition is nearly always an unintended effect, as well as hard to + > detect, so has been made an error. (The option setting + > NO_MULTI_FUNC_DEF turned this case into an error, but did not help + > with other cases and is off by default.) The alternative, of not + > expanding the alias, was rejected as it was more difficult to achieve + > in the parser and also would silently change the shell's behaviur + > between versions. A new option, ALIAS_FUNC_DEF, has been added, which + > can be set to make the shell behave as in previous versions. It is in + > any case recommended to use the "function" keyword, as aliases are not + > expanded afterwards. + + The common error message triggered by this change looks as follows: + + > zsh: defining function based on alias `foo' + > zsh: parse error near `()' + + See https://bugs.debian.org/871816 for more information. + + -- Axel Beckert <abe@debian.org> Fri, 11 Aug 2017 21:43:25 +0200 + zsh (5.0.0-1) unstable; urgency=low This update includes a rewrite of keyboard handling in `/etc/zsh/zshrc'. |
