Hi,
It seems with bash 4.3.30(1)-release (and probably others) that embedded
functions are output with a leading 'function ' keyword when using declare
-f / typeset -f. This is different to all other shells that support declare
/ typeset that I've tested (pdksh, mksh, Mac OS X ksh, which I think is
AT&T)
For instance, this entered at the shell:-
bye() {
echo dddd
}
helloworld() {
echo hello
embed() {
echo by
}
}
Produces this with typeset -f
helloworld ()
{
echo hello;
function embed ()
{
echo by
}
}
whereas pdksh, for instance, produces:-
helloworld() {
echo hello
embed() {
echo by
}
}
The other ksh88 derivatives are very similar apart from indentation, it
seems.
Is this by design? It's a little annoying for my situation*, as it makes it
impossible to consume the output from declare -f / typeset -f with another
POSIX shell (I am cognisant that of course ther emight be other bash syntax
in there, eg arrays, but I can code to make sure none is present). If
there's no workaround in bash itself, does anyone know a regex I could
apply safely to the output to remove the nested 'function ' statements. One
that is heredoc aware? Or am I going to have to write a parser (:-( ? Or is
there another way?
Many thanks
Raph
PS First posting of any note, so apologies in advance for any breach of
etiquette.
* PPS I have a couple of use cases, one of which is running a portion of
code under sudo from a generated script in a chroot where bash has not yet
been installed. Another is allowing user code additions. Such is life.
