Hi,
When we want to debug a script, we use the -x flag,
like `zsh -x script_name', and we get all the
variables that are set etc.
How do we debug a function, which is sourced from a
script, other than putting print statements manually
here and there.
Thanks,
sac.

% setopt xtrace
% my_func
% unsetopt xtrace
This debugs everything the shell does, including precmd() evaluation
and so on, thus there will be a little bit extra in the function.
Alternatively, you can mark the function as traced. The "typeset"
command won't blank the function when you call it like this:
% typeset -f -t my_func
This may be more useful if the function is being called from other
functions. However, the trace tagging needs to happen _after_ the
function is defined.
% typeset -f -t fred
% function fred { print "Foo: $*" }
% fred wibble
Foo: wibble
% typeset -f -t fred
% fred wibble
+fred:0> print 'Foo: wibble'
Foo: wibble
%
See zshoptions(1)/XTRACE and zshbuiltins(1)/typeset.
