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

The learn and use part can be done by studying a book; I recommend
then one mentioned previously in this newsgroup:
The AWK Programming Language
by Alfred V. Aho, Brian W. Kernighan, Peter J. Weinberger
A new edition is appearing soon, as we've been told.

If you're using GNU Awk I suggest (in addition) Arnold Robbins book:
Effective Awk Programming
Here you also get information about the GNU Awk's specific features.

GNU Awk has also debugging features; inspect Arnold's book or the
also online available GNU Awk documentation for details.

If you want to embed Awk in Emacs I cannot help you - myself using it
in a Unix system context from a shell command line -, but I'm sure
that the Emacs documentation will have some hints how to embed such
tools in Emacs.

Is the following usage of standard English grammar, as you have written above?

Better ask in a newsgroup were languages, grammar, and semantics are
discussed. Myself not a native speaker I've used principles from my
own language and some basic knowledge. What I can say (or speculate
about, if you like) is...
Relative clauses: A, B, C.
Clauses in dash: A - B - C. (Often written with long - or double -- .)
A composition of a relative clause with a dashed clause: A - B -, C.
where the first part of the relative clause contains a dashed clause.
Instead you can also use a parenthetical clause: A (B). or A (B) C.
or as a composition with a relative clause: A (B), C.
What you use depends on the intention, on what you want to express.
(Some native speaker may provide corrections or better explanations.)

I hope the clause composition didn't confuse you so much that the
expressed content was incomprehensible to you.
Syntactically you can parse A - B -, C. as {A{B}}{C} to see what
belongs semantically together.

PS: Reading Ludwig Wittgenstein's Tractatus Logico-philosophicus might
help (or maybe not).

See <https://groups.google.com/g/alt.usage.english/c/446LFA9rfDw/m/a1XF_QtzAgAJ> for further discussion on this question.

Thank you for your comments and explanations.
