Learn, use, and debug AWK in Emacs.

Learn, use, and debug AWK in Emacs.

[Hongyi Zhao]

Hi here,

Are there some feasible ways to learn, use, and debug AWK in Emacs?

Regards,
Zhao

Emacs has a major mode for editing Awk scripts.

For debugging, you can use the built-in debugger of GNU Awk (Gawk).
You can run Gawk from shell or Eshell buffers inside Emacs.

My main concern is the following features:

Real-time display the values of variables and test snippets
conveniently, and so on.

I don't think I understand what you mean by "real-time display" here,
but in any case you cannot have more that the Gawk built-in debugger
offers.  See the node "Debugger" in the Gawk manual for the details.
In particular, its section "Sample Debugging Session" can serve as a
tutorial and guided tour of the Gawk debugging capabilities in action.

If there are no replies from the Emacs community, then you might try
asking your question in the Usenet newsgroup ‘comp.lang.awk’.

Sure,

(defun awk-col (col)
  (interactive "scolumn: ")
  (insert (format "awk '{print $%s}'" col)) )
