Thank you for agreed my suggestion.
I have few things that I forgot to say in previous mail.
1) $cur should be surrounded by double quotes, otherwise directory names that
contain spaces cause a problem.
2) gdb finds a executable for the current directory as well as $PATH. however
gdb completion does not completes a executable in the current directory.
$ ls
my-program.c
$ gcc -g -o my-program my-program.c
$ gdb my-[TAB]
=> nothing completes.
Put PATH="$PATH:." to the front of compgen command allows compgen to search a
executable in the current directory.
In conclusion, I suggest following code.
COMPREPLY=( $( PATH="$PATH:." compgen -d -c -- "$cur" ) )
I wanted to fix the problem that gdb completion completes Bash's built-in
commands, functions and aliases.
but it is slightly hard to implement...
