Thanks; I guess that should make it possible to distinguish between the transpose operator and single-quoted strings (and the '' quoting sounds quite similar to how SQL quotes single quotes, so the code to handle that could be cribbed from sql.el). -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no

I'm new to Octave, so I could be wrong, but AFAIK single-quoted string
literals do not support line continuations. The only special construct
they may contain is '' which inserts a single '.
Quoth (info "(octave) Strings"):
Since the single-quote mark is also used for the transpose operator
(*note Arithmetic Ops) but double-quote marks have no other purpose in
Octave, it is best to use double-quote marks to denote strings.
Quoth (info "(octave) Escape Sequences in String Constants"):
In double-quoted strings, the backslash character is used to introduce
=E2=80=9Cescape sequences=E2=80=9D that represent other characters. For =
example, =E2=80=98\n=E2=80=99
embeds a newline character in a double-quoted string and =E2=80=98\"=E2=
=80=99 embeds a
double quote character. In single-quoted strings, backslash is not a
special character. Here is an example showing the difference:
[...]
In a single-quoted string there is only one escape sequence: you may
insert a single quote character using two single quote characters in
succession. For example,
'I can''t escape'
=E2=87=92 I can't escape
Quoth (info "(octave) Continuation Lines"):
In the Octave language, most statements end with a newline character and
you must tell Octave to ignore the newline character in order to
continue a statement from one line to the next. Lines that end with the
characters =E2=80=98...=E2=80=99 are joined with the following line befor=
e they are
divided into tokens by Octave=E2=80=99s parser. For example, the lines
x =3D long_variable_name ...
+ longer_variable_name ...
- 42
form a single statement.
Any text between the continuation marker and the newline character is
ignored. For example, the statement
x =3D long_variable_name ... # comment one
+ longer_variable_name ...comment two
- 42 # last comment
is equivalent to the one shown above.
Inside double-quoted string constants, the character =E2=80=98\=E2=80=
=99 has to be
used as continuation marker. The =E2=80=98\=E2=80=99 must appear at the =
end of the line
just before the newline character:
s =3D "This text starts in the first line \
and is continued in the second line."
Apparently ellipsis continuation lines were also once supported in
double-quoted string literals:
octave:1> "foo ...RET
warning: '...' continuations in double-quoted character strings are
obsolete and will not be allowed in a future version of Octave;
please use '\' instead

indeed, the ' character is the transpose operator (like in matlab),
and that patch makes emacs essentially useless for octave. Without it,
everything looks fine as I just verified.
Note that the ' character as a string occurs only in pairs, which is
(hopefully) unambiguous.

This is due to the following patch:
commit 9e68413c7f0a7f71e1cee923ace7282d14c2e686
Author: Noam Postavsky <npostavs@HIDDEN>
AuthorDate: Mon Aug 24 17:33:49 2020 +0200
Fix inferior octave single-quote font lock
* lisp/progmodes/octave.el (octave-mode-syntax-table): Fix
fontification of single quotes in inferior octave mode (bug#25517).
It looks like the problem is that octave-mode-syntax-table sets single
quotes as punctuation even though GNU Octave's manual says single quotes
are string syntax [1].
[1]:
https://www.gnu.org/software/octave/doc/interpreter/String-Objects.html
And, indeed, that link says:
"A character string in Octave consists of a sequence of characters
enclosed in either double-quote or single-quote marks."
But the ' character is also a transposition operator? I don't know
Octave at all -- this seems like a rather ambiguous syntax?
