Subject: Re: [ast-developers] More type problems
--------
File A_t contains:
typeset -T A_t=(
B_t b
)
File B_t contains:
typeset -T B_t=(
integer n
)
Both are in a directory which is included in FPATH. Is B_t supposed to
be loaded automatically? What I get from
A_t a
is:
-ksh: B_t: not a known type name
-ksh: A_t: not found [No such file or directory]
Apparently ksh wants B_t to be defined before A_t is sourced. I put an
explicit "source B_t" at the beginning of A_t, but that didn't change
anything.
This is a difficult one and the fix will not be in the next release.
The problem is that the parser has to know that B_t is a type.
I might be able to have the parser search FPATH which would fix you problem,
but I have to think about how to handle this in the compiler.
I might require that you put the command
B_t
without arguments before typeset -T A_t
Hm, if I put the command B_t in the file A_t, I get the same errors as
before. However, it works if 'B_t' is executed in the topmost level:
#!/usr/bin/ksh
FPATH=.
B_t
A_t a
There is still a problem if A_t contains an array declaration like
typeset -T A_t=(
B_t -a b
)
This causes a segmentation fault.
