I am including a long list of greek characters (\alpha \beta \gamma) when
using texinfo, and want to inquire how to list them in a multiline expression.
Here I am using one line.
(defconst supinf-greek-keywords
'(("\\\\\\<\\(alpha\\|beta\\|gamma\\)\\>"
(1 'typeface-greek-keywords)))
"Rules to apply font-lock highlighting.")

You mean, in the expression? Like
#+begin_src emacs-lisp
(defconst supinf-greek-keywords
`((,(concat "\\\\\\<\\("
(mapconcat #'identity (list "alpha" "beta" "gamma") "\\|")
"\\)\\>")
(1 'typeface-greek-keywords)))
"Rules to apply font-lock highlighting.")
#+end_src
?
It would be best to use an appropriate `rx' expression instead of
`concat' as above if you know `rx' or want to get used to it. Would
make the result even more readable.
Regards,
Michael.

Never came across rx before.
Have used
(defconst crucible-mtksy-keywords
`(;; Greek
(,(concat "\\\\\\<\\(alpha\\|beta\\|chi\\|delta\\|"
"Delta\\|epsilon\\|varepsilon\\|eta\\|"
"gamma\\|Gamma\\|iota\\|kappa \\|"
"lambda\\|Lambda\\|mu\\|nu\\|"
"omega\\|Omega\\|phi\\|varphi\\|"
"Phi\\|pi\\|varpi\\|Pi\\|"
"psi\\|Psi\\|rho\\|varrho\\|"
"sigma\\|varsigma\\|Sigma\\|tau\\|"
"theta\\|vartheta\\|Theta\\|upsilon\\|"
"Upsilon\\|xi\\|Xi\\|zeta\\)\\>")
(0 'crucible-mtksy-tfc)) ;
It would help if I had an example of using "rx" for this.

That would look like this (you want to add the missing greek letter
names):
(defconst crucible-mtksy-keywords
`(;; Greek
(,(rx "\\" word-start
(or "alpha" "beta") ;add the other letters here
word-end)
(0 'crucible-mtksy-tfc))))
The result will be a slightly optimized regexp (equivalent to yours of
course).
If you want to go that way, I think it would also be possible to avoid
the repetition of uncapitalized followed by a capitalized letter name.
HTH,
Michael.

I am using font lock to highlight keywords in a minor mode.
Have changed from using "concat" to using "rx" as you suggested.
However it does not seem equivalent.
(defconst crucible-mtksy-keywords
`(;; Greek
(,(concat "\\\\\\<\\(alpha\\|beta\\|chi\\|delta\\|"

"sigma\\|varsigma\\|Sigma\\|tau\\|"
"theta\\|vartheta\\|Theta\\|upsilon\\|"
"Upsilon\\|xi\\|Xi\\|zeta\\)\\>")
(0 'crucible-mtksy-tfc)))
"Fontification for letters and symbols.")
(defun crucible-mtksy-tfc ()
"Font-lock setup for mathematical symbols."
(font-lock-flush (point-min) (point-max))
(if crucible-mode
(progn
(font-lock-add-keywords nil crucible-mtksy-keywords t)
(font-lock-add-keywords nil crucible-supinf-font-lock t))
(font-lock-remove-keywords nil crucible-mtksy-keywords)
(crucible-supinf-disable (point-min) (point-max)))
(font-lock-flush (point-min) (point-max)))

How does your rx version look like?

Had made it as you suggested, but I think there has to be some changes
that have to be done in the regexp.
Have used
(defconst crucible-mtksy-keywords
`(;; Greek
(,(rx "\\" word-start
(or "alpha" "beta") ;add the other letters here
word-end)
(0 'crucible-mtksy-tfc))) )
In the expression (1 'crucible-mtksy-tfc), the "1" is an option to not
highlight the starting "\".

I know that the command
(rx (or "alpha" "beta"))
produces the generated pattern
"\\(?:alpha\\|beta\\)"

You can try to use
(require 'rx)
(rx "\\" "alpha" (or "beta" "gamma") "theta")

As you pointed out, I misunderstood how to use rx.
However when I applied the change, the keywords are not being
highlighted at all.
`(;; Greek
(, (rx "\\" "alpha" (or "beta" "chi") "delta")
(1 'crucible-mtksy-tfc))
(,(concat "\\\\\\<\\(Delta\\|epsilon\\|varepsilon\\|eta\\|"

Have also tried to do the following, but it still has remained a problem.
(defconst crucible-mtksy-keywords
`(;; Greek
(,(concat "\\\\\\<"
(rx "\\" "alpha" (or "beta" "chi") "delta")

That would match something like \alphabetadelta. I guess that's not
what you want.
If you want to refer to a submatch, e.g. to what is matched by the `or'
subexpression, use an explicit `group'.

Should I still try to use "rx" for my situation?

I would do it, it makes the regexp better readable. That's why I
mentioned it. Of course it takes a bit of extra time to learn the
syntax. It's totally ok to go without `rx'.

Michael.

In my Emacs version it's described in the manual:
(info "(elisp) Rx Notation")
Do you have that? AFAIR that chapter had been added to Emacs not that
long ago.

Have looked at the Emacs Lisp Manual from the Online Emacs Documentation.
I now understand why you used word-start and word-end, but still need
some serious help to get an equivalent expression for my regexp.

The Emacs Lisp manual has a pretty extensive documentation
on it:
34.3.3 The ‘rx’ Structured Regexp Notation
Alternatively, in the Interwebs here [1].

I wantt to make the equivalent to the following, but still find
difficulty doing it.
(,(concat "\\\\\\<\\(alpha\\|beta\\|gamma\\)\\>")

There's something missing up there. I'll try with just
"\\\\\\<\\(alpha\\|beta\\|gamma\\)\\>"
The first four backslashes translate to one escaped backslash:
(rx "\\" ...)
(two backslashes, because of Lisp string literal syntax)
Now comes a word start ("word-start" or "bow"; I'll go with the
more readable "word-start"):
(rx "\\" word-start ...)
Next is a group, followed by a word-end:
(rx "\\" word-start (group ...) word-end)
Within the group, there is an alternative:
(rx "\\"
word-start
(group
(or ...))
word-end)
Now the alternative's content:
(rx "\\"
word-start
(group
(or "alpha" "beta" "gamma"))
word-end)
You can check that by evaluating it in a Emacs Lisp buffer (e.g.
this *scratch* buffer Emacs comes up at start): put point after
the whole expression and hit C-x e. You get:
"\\\\\\<\\(\\(?:\\(?:alph\\|bet\\|gamm\\)a\\)\\)\\>"
There are some spurious non-capturing groups (?: ...), and it
even factored out the trailing -a from "alpha"... etc., but
should be equivalent.
Does it help?
Cheers
