[Cgdb-devel] Patch: Searching & entering :ex commands

[Mike M. <mi...@su...>]

Bob,

When you get a chance, I'd like you to review the attached patch.
It does the following things:

1. Bug fix: If you start searching for something, but abort (hit ESC),
the regex_line variable was obliterated, so 'n' or 'N' no longer finds
the last searched regex.  I renamed regex_line to regex_last, and
created a regex_cur for the currently-being-typed regex.  Now if you
give up searching, you can still 'n' for the last searched string.

2. Bug fix: Start cgdb, hit ESC, start searching for something, hit ESC,
hit ':' and the status bar displays :(null).  Fixed this.

3. Feature: If you are typing a :ex command or a regex search, and you
backspace when the command/regex is empty, the command or search is
aborted (like vim does).

4. Fixed a warning about casting pointer to int of different size
compiling on a 64-bit platform.

I tried to test this well, but I wanted your input before I commit it.

Thanks!
Mike
