IIRC Steve Purcell (who shares his config publicly for many other users) used to have mmm-mode apply sql-mode inside Ruby heredocs (which are fancy multiline strings, basically) that are "tagged" to contain SQL. And here's somebody else who wanted to have html-mode inside a JS string: https://github.com/dgutov/mmm-mode/issues/142 The intermediate conclusion there is to use a ts-based config, though. And as far as show-paren-mode goes, this might be something that mmm-mode itself could have workarounds for anyway.

A solution would be to make "syntax tables" more complex so as to be
able to have a notion of "context" (so the same character can behave
differently inside a string than outside), or equivalently a way to
use different syntax tables in different contexts.

Other than via things like `mmm-mode` (which I've never seen used to
use different modes in strings than in code), I don't think they can.

I'm not sure if this should be closed as notabug or not, but I'm tagging it as wishlist at least. Feel free to close if that makes more sense.

I think that's the idea, indeed. Of course, we don't have to obey the
Emacs Lisp syntax, but I think it makes sense to do so.
Admittedly, it would be nice to allow the use of other syntax rules inside
comments and string for these kinds of situations.

Emacs -Q 2. M-x eval-expression ``` (progn (setq cursor-type 'bar) (show-paren-mode 1)) ``` 3. Paste the following text in any .el file ``` (=E8=8B=B1=E6=96=87=E6=8B=AC=E5=8F=B7) (=E8=8B=B1=E6=96=87 =E6=8B=AC=E5=8F=B7) =EF=BC=88=E4=B8=AD=E6=96=87=E6=8B=AC=E5=8F=B7=EF=BC=89 =EF=BC=88=E4=B8=AD=E6=96=87 =E6=8B=AC=E5=8F=B7=EF=BC=89 ``` 4. Place the cursor at the first position (or last position) of each line. The expected behavior: All of the four lines above match and highlight correctly The actual behavior: The 4th line mismatched. Note the middle SPC character= . P.s. 1. This issue only occurs in lisp-like modes. It is OK in c-mode and python-mode. 2. =E3=80=90=E3=80=91=E3=80=8C=E3=80=8D=E3=80=8E=E3=80=8Fhave the same prob= lem. They are also commonly used in lisp comment. 3. A simple investigation found that it may be related to `scan-sexps` or syntax-table, because `(scan-sexps outside dir)` in the `show-paren--default` returns the wrong value in the 4th case. 4. More screenshots and test code can be found in https://emacs-china.org/t/show-paren-mode/15160 Emacs 29.3 on Windows. Thanks.
