Suppose your function is longer than your emacs window. Use "expression" as "show-paren-style", then go just after the last closing parenthesis. You get the associated region highlighted.

First, what exactly do you mean by "scroll up the code"? which Emacs commands did you use to scroll? At least some ways of scrolling don't move point. And when you say "point moves across the window", do you mean that point moves with the text or that the text moves, but point stays at the same screen coordinates? Depending on how you scroll, it could be one or the other. Next, what do you mean by "highlighting get recomputed as the point moves across the window"? What happens with highlighting as you "scroll" that you don't like? And finally, what would you like to happen instead in this case? ^ permalink raw reply [flat|nested] 20+ messages in thread

If the point stays at same screen coordinates, or moves with the text; the point still moves from its original position (originally positioned after parenthesis of interest). Have noticed that when I scroll, the cursor point always shown up in the window. > Next, what do you mean by "highlighting get recomputed as the point > moves across the window"? What happens with highlighting as you > "scroll" that you don't like? Let there be a long function, and you put the cursor at the point following the last parenthesis. With "show-paren-style" being expression, the function code get highlighted. Suppose I want to go to the beginning of the function which resides outside the window pane. The highlighting is disabled as I go to the beginning of the function. > And finally, what would you like to happen instead in this case? I would like the possibility of freezing the highlighting (not only when using 'expression put also for 'parenthesis). Currently I loose all the parenthesis or expression highlighting when I need to move through the code. ^ permalink raw reply [flat|nested] 20+ messages in thread

Anyway, if this is what you want, then show-paren-mode is not the solution. show-paren-mode is explicitly programmed to show you the parenthesized/braced construct before/after point, so if you move point, you cannot expect the highlight to remain "frozen". ^ permalink raw reply [flat|nested] 20+ messages in thread

Is it not possible to add a toggle function to keep the highlighting once some function is called, then call it again to have show-paren-mode work normally again.

There are many function longer than the height of a normal emacs window. Thusly I fail to conclude that it is a rarely-needed functionality. Because the show-paren-mode functionality fails when the window is small or the function is long, technically it should be considered a bug. ^ permalink raw reply [flat|nested] 20+ messages in thread

Suppose you are using expression style. Suppose you want to see if the last parenthesis matches the one before defun.

DOCSTING "Toggle visualization of matching parens". How can one visualise a matching parens if the matching parens is not viewable in the window? "show-paren-mode" should be upgraded, so that we would not need to find another one which is not built-in. At any rate, finding another one would make "show-paren-mode" obsolete. ^ permalink raw reply [flat|nested] 20+ messages in thread

By default the matching paren's nearby text is displayed in the echo area if it's outside of the visible part of the buffer. Stefan ^ permalink raw reply [flat|nested] 20+ messages in thread

Can there be a solution to this? There are many ways to achieve that: - C-M-b C-M-f to move backward and forward a balanced expression. - Delete and reinsert the parenthesis. You will see in the echo area the text "Matches ..." that informs you about the matching parenthesis. - In Emacs 29, I introduced a new defcustom for show-paren-mode, show-paren-context-when-offscreen, which will automatically show the matching parenthesis information in the echo area when the point is next to the closing parenthesis, without needing to reinsert it. ^ permalink raw reply [flat|nested] 20+ messages in thread
