Hello to all. Thanks again for participating.
After the post @Don_Cragun I added explanations to each example
Not very elegant but it just works
Code:
#!/bin/bash
:<<SPRAVKA
It works only with a single line.
it is possible with spaces.
SPRAVKA

while read -d, P; do
        T=$T$d$P
        echo -n "$t| ($T) $P"
        d=,
        t=" "
done < file
echo -n " | "
grep -o '.$' file

It's simple and don't even need to use "hold spase".
This works with each line separately.
Code:
sed -rn 's/.$/ | &/; :1;s/^(\S*)(.),/\1 | (\1\2) \2/;t1;s/^ //p' file

Here in my opinion there is elegance but I doubt the effectiveness of the work
This works with all strings as if one ends with a comma excluding the last
Code:
awk 'RT {T = T (T?RS:"(") $1; printf "| " T ") " $1 FS; next} {print "| "$1}' RS=, file

gst-complete

gst-complete-0.8(1)						   User Commands					       gst-complete-0.8(1)

NAME

       gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines

SYNOPSIS

       complete -Cgst-complete-0.8 gst-launch

       gst-complete [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
       gst-launch command lines.

       You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.

       gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
       complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.

OPTIONS

       The following options are supported by gst-complete-0.8 and gst-complete:

       --help	       Display detailed usage message. You can also use -? to specify this option.

       The following options are supported by gst-complete only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Generating the Registry of Available Plugins by Running gst-compprep

       Run the following command in your .bash_profile or other appropriate place:

       example% complete -C gst-complete-0.8 gst-launch

       Example 2: Running the Wrapper Script and Displaying the Command Name

       example% gst-complete --print
       /usr/bin/gst-complete-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-complete-0.Executable for bash completion for gst-launch

       /usr/bin/gst-complete   Wrapper script that runs the latest installed version of gst-complete-X.X
