awk, shell script reverse engineering app generator - project

Hi,

this is fantastic forum for shell programming and scripting,
so please let me to introduce you with my very old concept to
have web form/s with radio, select, input fields
and have an application generating valid, syntax error free scripting code.

The same or alike questions are asked over and over again, so
one question generates one or more valid code answer.

Basing on top-down program solving, programming, any complicated computational problem can be divided into a number of basic problem and so on, down to the bottom.

As the problem has been already solved in html/www environment, providing wysiwyg html applications,
please tell me how to start building such valid script code generator from the scratch.

Basing on some experience in gps navigation systems,

I started testing many many gps navigation applications.
Acquired about 10 gps devices, usb gps, Bluetooth gps, Ps2 gps, agps in my Motorola A1000, in Nokia Tablet and more.

Ok.
First step is gps device
I connected bluetooth dongle to Linux server,
connected BT gps device to it
learned how to read NMEA sentences
learned basics of awk to process NMEA sentences

Now I can try to extract data fields of interest to me from NMEA stream.

Next step is to process such data and build basic graphical interface (no maps) to view data on-line.

Such basic application/ script under Linux is dialog for its simplicity.

Ok.
I have gps + gps data processed, dialog viewer, what can I do next.

Next step is map viewer + POI database + mysql server, routes, routing algorithm implemented, ..

But basics is exactly shell script app generator.
One good idea is to build web form for the modification of examples shell scripts to fit our needs.

So reverse engineering comes into my mind.

Shell script parser, syntax resolver, debugger,.

Another nice solution is to build pipelines made of objects (ocx like)
and have visualization tool - pipes to have objects connected.

Is anything of this kind already available ?

Foundation for this project are libraries of shell script examples with good description - HowItWorks.

Happy New Year

BTW
Human shell script app generators already live on this nice forum.

igawk

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
