[Bashdb-devel] Recent bash debugger changes.

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

I am currently planning a release around March 15, the ides of March.

Changes include:

 - Updates for bash 4.2
 - syntax coloring if  the Python pygments package installed (and
--highlight option used)
 - easy way to evaluate the current source line or expression inside the
source line (debugger commands "eval" and "eval?")
 - ability to go into a nested shell but keeping existing variables  and
functions set. (debugger command "shell")  With this, one needs...
 - ability to save variables to an outer shell  ("set_vars" function inside
the interactive shell)
 - ability to save values from inside a subshell  to the outer shell
(debugger command "export")

Haven't done this yet, but nested debugging of expressions. Previously I
allowed only file names and
I wasn't setting variables properly there.

As I work more and more with debuggers, I slowly learn more about how to do
this better, more easily and how to
write better POSIX shell code. Each release helps me cover up
the embarrassment of code and poorly-
written code of the previous base. (There is still plenty of flaky code in
there that should be improved.)
