[Bashdb-remake] Ever wanted "rake --tasks" for GNU Make?

[Rocky B. <ro...@gn...>]

Have you ever wanted "rake tasks" for GNU Make? That is you have some
strange Makefile and you want to see the interesting targets, that you can
run "make *target-name*" on?

Well I have. So I added it.

remake --targets

shows a list of explicit target names. Implicit patterns such as those that
have % in them are not in this list. As a nod to *rake*, *remake --tasks* does
the same thing.

Still in the list are file names which are likely to be boring and those
extension-matching patterns. So if you want to exclude these from the list,
try:

remake --tasks | grep -v '/' | grep -v '\.'

The longer story is this. Inside the debugger, it is useful to see a list of
locations you can stop at or set a breakpoint. This is called "info
targets". Run "help info targets" for information on how to run that. After
putting this in, I realized it might be interesting just to list the target
names. So that was next added. And then I found myself running:

echo "info targets name" | remake --debugger

This shows also the debugger prompts and has is a little cumbersome, so I
added it as an option.

Down the line, I will probably split off --targets from --tasks. The later
will exclude targets without commands to remake the targets. For example
with file names that are supposed to exist and are not derived from some
other file would be excluded. Also I should exclude targets that match
extensions like *.c.o*
