Bash-completion on shell script
Hello
I want use bash_completion on a script but the information on the internet give me not a solution.
The scrip start with "cd" to a direction
Than the script do "ls"
Than I must give a name of a sub-direction and here I want to use <TAB>, so when I have a direction with the name
smith and I give sm and than <TAB> than I want completion to smith.
When I have two names who begin with sm I must see the two possibilities.
When I use <TAB> on the terminal than everything works fine.
Only not from within a script.
Thanks anyway

TAB completion is a feature of the interactive shell. If you are executing a script you are not interactive anymore. If you want tab completion when you are writing a script, that's a feature that your editor must have.

You either want a select menu or read: An Introduction to Programmable Completion

As in:
Code:
select ITEM in $(ls);do
    echo "do your stuff"
    break
done

Hope this helps

I wanted to implement this as well for some of my scripts, but me didnt feel confident enough to try.
Now i tried, and YEAH !!! *dance*

This is what i've achieved in about an hour from knowing nothing about it.
Its dirty, its bugy, but when it agrees to work, heck - i love that it lists my prj dir Smilie
Code:
# bash completition for dev-scripts
# 2014.11.16 by sea
#
#	Dynamic attempt
#
	_ds_base_dir()
	{
		# NOT USED YET
		echo /usr/share/dev-scripts/menu
	}
	_ds_list_prjs()
	{
	    COMPREPLY=( $( compgen -W "$(cd $HOME/.config/dev-scripts/prjs;ls)" -- "$2" ) )
	    return 0
	}
#
#	Fixed lists
#
	_ds_mod_git()
	{
		COMPREPLY=( $( compgen -W "add commit edit status upl" -- "$2" ) )
	}
	_ds_mod_ks()
	{
		COMPREPLY=( $( compgen -W "add edit make" -- "$2" ) )
	}
	_ds_mod_rpm()
	{
		COMPREPLY=( $( compgen -W "add changelog edit list make" -- "$2" ) )
	}
	_ds_mod_prj()
	{
		COMPREPLY=( $( compgen -W "git ks rpm edit list" -- "$2" ) )
	}
	_ds_mod_ssh()
	{
		COMPREPLY=( $( compgen -W "info make setup" -- "$2" ) )
	}
	_ds_mod_new()
	{
		COMPREPLY=( $( compgen -W "manpage" -- "$2" ) )
	}
	_ds_mod_menu()
	{
		COMPREPLY=( $( compgen -W "new prj ssh add make review setup" -- "$2" ) )
	}
	_dev_scripts()
	{
		COMPREPLY=()
		case $3 in
		add|make|list|edit|review)
			complete -F _ds_list_prjs -o filenames ds	;;
		setup)	return 0						;;
		new)	complete -F _ds_mod_new -o filenames ds			;;
		prj)	complete -F _ds_mod_prj -o filenames ds			;;
		ks)	complete -F _ds_mod_ks -o filenames ds			;;
		rpm)	complete -F _ds_mod_rpm -o filenames ds			;;
		git)	complete -F _ds_mod_git -o filenames ds			;;
		ssh)	complete -F _ds_mod_ssh -o filenames ds			;;
		esac
	}
	complete -F _dev_scripts -W 'add make review setup new prj ssh' ds

@ thailand: Hope this helps

@ others:
One question remains, anyone knows how i can 'fix' the read/shown values?
I assume i need to implement another 'layer' of case statement within functions?

Thank you in advance
