Subject: emulate -L sh impact on $0, $argv
To: Zsh hackers list <zsh-workers@zsh.org>
Content-Type: text/plain; charset=UTF-8

Hello
Is this expected behavior:

% echo 'echo Hello, my 0 is $0, argv0 is ${argv[0]}' > test_file.sh;
source() { emulate -L zsh; builtin source "$@"; }; source
./test_file.sh
Hello, my 0 is ./test_file.sh, argv0 is

% echo 'echo Hello, my 0 is $0, argv0 is ${argv[0]}' > test_file.sh;
source() { emulate -L sh; builtin source "$@"; }; source
./test_file.sh
Hello, my 0 is source, argv0 is ./test_file.sh

Sometimes -L zsh gives correct argv[0], couldn't clarify exactly when,
it may have something to do with reversed order of the calls.

Best regards,
Sebastian Gniazdowski
