[...] > In such cases all whitespace should be compacted more... I think that's a good idea; anybody got a comment here? This could be implemented kinda simply by looking at the mode line string after it's been generated, and shortening spaces if the text is too long.

I'm not sure that's generally useful -- when chopping down a field, there's often field-specific ways to shorten things (i.e., just chopping the ends off of things isn't always the best thing to do). But in any case, it's orthogonal to whether to compact the white space, which entails no information loss and can be done generally.

I think. I had a look at this, thinking that this would be easy to implement. We could have, for instance, a variable like `mode-line-compact' that would default to nil (current behaviour), t (always compact) and `long' (compact if the mode line is wider than the window size). However, the mode line generation is done in a very low-level manner -- in display_mode_element. And it calls display_string directly for each element? If I'm reading the code correctly? static int display_mode_line (struct window *w, enum face_id face_id, Lisp_Object format) [...] mode_line_target = MODE_LINE_DISPLAY; Yeah, I think so. So it doesn't create a string, and then display it, so there's really no way to post-process the entire string before it's displayed, I think? Which makes this rather difficult to implement. Hm... well, since this is an optional thing users can switch on, perhaps making it slightly slower wouldn't be that much of a problem.

This is Lisp converted into C, yes? And it formats the mode-line twice: once in format-mode-line, then again in display_string, right? You don't need all this inelegance. After display_mode_element returns, you have all the glyphs it produced in it.glyph_row, so you can simply remove the unneeded space glyphs from the glyph row (and adjust the metrics accordingly). Let me know if you need more detailed help in how to do that.

It's basically the same loop as you do on characters of the string produced by Fformat_mode_line, just done on elements of it.glyph_row->glyphs[TEXT_AREA], which is a linear array of 'struct glyph'. Each glyph tells you what character it displays (and much more). There are gobs of similar code in xdisp.c. For example, here's how we make space in a glyph row for prepending a character (needed when displaying R2L lines): struct glyph *g; /* Make room for the additional glyph. */ for (g = glyph - 1; g >= it->glyph_row->glyphs[area]; g--) g[1] = *g; glyph = it->glyph_row->glyphs[area]; IOW, it's just an array of simple objects, not unlike array of characters, a.k.a. "a string". If this still sounds complicated, I can volunteer to write the code myself, if you promise to write tests for the feature ;-) Thanks.

I'm not very familiar with that code, but from my reading of it, none of that has been done at this point. I call Fformat_mode_line (format, Qnil, Qnil, Qnil); instead of display_mode_element. Fformat_mode_line sets mode_line_target = MODE_LINE_STRING; or the like, and then calls display_mode_element, which then won't call display_string at all, but just put all the computed elements in a list. So nothing is displayed until that call to display_string, in my reading of the code.

You don't really have a string here, you need to generate it first, from several individual C and Lisp strings, and from :eval expressions. Generating it involves employing some of the same code that display_mode_element calls, but in a context that was not meant for display, so I'm not even sure the result will be the same (i.e. we risk inadvertent changes in behavior). We will also be consing at least one more Lisp string, so displaying a mode-line under this option will produce more garbage. All of these are IMO disadvantages that don't exist in my proposal. And I don't see why post-processing would be less efficient. Can you explain why you think so?

Ah, I misunderstood what you meant here -- I thought you wanted to change my patch to call display_string on the result from Fformat_mode_line, and then alter the glyph matrix. :-/ But, yes, what you're saying makes total sense -- rendering the mode line as normal, and then changing the glyphs to remove the spaces would be more efficient and create less garbage. I didn't think this extra garbage on mode line updates didn't matter much, especially since `mode-line-compact' would be a user option defaulting to nil. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no From debbugs-submit-bounces@debbugs.gnu.org Sat Aug 08 07:18:43 2020 Received: (at 34476) by debbugs.gnu.org; 8 Aug 2020 11:18:43 +0000 Received: from localhost ([127.0.0.1]:58302 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1k4Ms7-0008E7-MO for submit@debbugs.gnu.org; Sat, 08 Aug 2020 07:18:43 -0400 Received: from quimby.gnus.org ([95.216.78.240]:50446) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1k4Ms5-0008Di-By for 34476@debbugs.gnu.org; Sat, 08 Aug 2020 07:18:41 -0400 DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed; d=gnus.org; s=20200322; h=Content-Type:MIME-Version:Message-ID:In-Reply-To:Date: References:Subject:Cc:To:From:Sender:Reply-To:Content-Transfer-Encoding: Content-ID:Content-Description:Resent-Date:Resent-From:Resent-Sender: Resent-To:Resent-Cc:Resent-Message-ID:List-Id:List-Help:List-Unsubscribe: List-Subscribe:List-Post:List-Owner:List-Archive; bh=v9CANNHAh/n9mKLHNC2iQEQnRwFwUyBIt7O8ZXTAYjM=; b=i1N8seQTZrmIGsSYd0qoMJr3ic KNay5ICTKX6dFgLn7ocauf9ht8MBgZ9PV6qsXWKmAQiBuHKscQDWN30amWSMUCHh/9qX5eVnvw6sF b6gsxNyuAqjnqY3oGLWytqZvvRG25rnu+rUEiZpj/v7PSn9Z+D4KcrxPhEoV46WFlyGs=; Received: from cm-84.212.202.86.getinternet.no ([84.212.202.86] helo=xo) by quimby with esmtpsa (TLS1.3:ECDHE_RSA_AES_256_GCM_SHA384:256) (Exim 4.92) (envelope-from ) id 1k4Mrw-0003XB-6h; Sat, 08 Aug 2020 13:18:35 +0200 From: Lars Ingebrigtsen To: Eli Zaretskii Subject: Re: bug#34476: fluffy whitespace in the mode-line, despite it running off the screen References: <87lg2icx3u.fsf@jidanni.org> <87ftnfrwef.fsf@mouse.gnus.org> <87r26z0wdy.fsf@tcd.ie> <87eeoi7un0.fsf@gnus.org> <87a6z67t7p.fsf@gnus.org> <83364y8ze0.fsf@gnu.org> <878seq8yzo.fsf@gnus.org> <83y2mq7jk7.fsf@gnu.org> <87mu367iue.fsf@gnus.org> <83sgcy7ebz.fsf@gnu.org> <87wo295wob.fsf@gnus.org> <83364x79jl.fsf@gnu.org> <83zh755udw.fsf@gnu.org> Date: Sat, 08 Aug 2020 13:18:30 +0200 In-Reply-To: <83zh755udw.fsf@gnu.org> (Eli Zaretskii's message of "Sat, 08 Aug 2020 13:01:15 +0300") Message-ID: <87k0y94c8p.fsf@gnus.org> User-Agent: Gnus/5.13 (Gnus v5.13) Emacs/28.0.50 (gnu/linux) MIME-Version: 1.0 Content-Type: text/plain X-Spam-Report: Spam detection software, running on the system "quimby.gnus.org", has NOT identified this incoming email as spam.

text/plain There's four spaces between *scratch* and All because they have different faces... which makes me wonder why there's trailing spaces in the buffer name at all, instead of just three spaces after the buffer name in the mode line format?

I have an idea, but > I need to test how well it works. Turns out my original idea of post-processing the glyphs is unworkable. The problem I didn't consider is that glyphs are only produced up to the limit of the window-width, so once the full mode-line becomes longer than that, any post-processing cannot recover the glyphs beyond the window edge, because they were never produced in the first place. The alternative which I would like to try implementing is to modify the code of display_string so that it doesn't produce multiple space glyphs, replacing them with a single glyph, when this option is non-nil. Since display_mode_element always calls display_string to produce the glyphs, this should allow us to solve the problem cleanly. Stay tuned.

(I.e., only compact if the line is too long.) We could perhaps do that at the price of producing the glyphs twice: first without squeezing spaces, then with squeezing if the result is a truncated mode line. But first I need to see if this new idea "holds water".

Note that this is slightly sub-optimal, because if 2 Lisp strings are displayed one after another, and the first one ends with a space, while the second one begins with a space, this will not be squeezed, because we consider each string separately. If this is not acceptable, then we will have to go back to your original proposal of using Fformat_mode_line (although I'm still unhappy with doing that, as we had over the years quite a few complaints that the result is not exactly identical to the displayed mode line). If the patch below is deemed "good enough", we will probably need to implement something similar for Fformat_mode_line, because users might expect the latter to produce a similarly squeezed whitespace. diff --git a/src/xdisp.c b/src/xdisp.c index 4fe1c42..d9f6bea 100644 --- a/src/xdisp.c +++ b/src/xdisp.c @@ -26883,6 +26883,25 @@ display_string (const char *string, Lisp_Object lisp_string, Lisp_Object face_st row->phys_height = it->max_phys_ascent + it->max_phys_descent; row->extra_line_spacing = it->max_extra_line_spacing; + bool space_seen = false; + bool squeeze_spaces_p = false; + if (!NILP (Vmode_line_compact)) + { + int remapped_modeline_face_id = MODE_LINE_FACE_ID; + int remapped_inactive_modeline_face_id = MODE_LINE_INACTIVE_FACE_ID; + if (!NILP (Vface_remapping_alist)) + { + remapped_modeline_face_id + = lookup_basic_face (it->w, it->f, MODE_LINE_FACE_ID); + remapped_inactive_modeline_face_id + = lookup_basic_face (it->w, it->f, MODE_LINE_INACTIVE_FACE_ID); + } + /* We only squeeze multiple spaces when displaying mode lines. */ + squeeze_spaces_p + = (it->base_face_id == remapped_modeline_face_id + || it->base_face_id == remapped_inactive_modeline_face_id); + } + if (STRINGP (it->string)) it_charpos = IT_STRING_CHARPOS (*it); else @@ -26898,6 +26917,19 @@ display_string (const char *string, Lisp_Object lisp_string, Lisp_Object face_st if (!get_next_display_element (it)) break; + if (squeeze_spaces_p) + { + if (it->char_to_display == ' ' && it->face_id == it->base_face_id) + { + if (space_seen) + goto next_char; + else + space_seen = true; + } + else + space_seen = false; + } + /* Produce glyphs. */ x_before = it->current_x; n_glyphs_before = row->used[TEXT_AREA]; @@ -26962,6 +26994,7 @@ display_string (const char *string, Lisp_Object lisp_string, Lisp_Object face_st if (i < nglyphs) break; + next_char: /* Stop at line ends. */ if (ITERATOR_AT_END_OF_LINE_P (it)) { From debbugs-submit-bounces@debbugs.gnu.org Sat Aug 15 06:55:45 2020 Received: (at 34476) by debbugs.gnu.org; 15 Aug 2020 10:55:45 +0000 Received: from localhost ([127.0.0.1]:54332 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1k6tqj-0007fg-2J for submit@debbugs.gnu.org; Sat, 15 Aug 2020 06:55:45 -0400 Received: from quimby.gnus.org ([95.216.78.240]:52466) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1k6tqh-0007fU-Ff for 34476@debbugs.gnu.org; Sat, 15 Aug 2020 06:55:44 -0400 DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed; d=gnus.org; s=20200322; h=Content-Type:MIME-Version:Message-ID:In-Reply-To:Date: References:Subject:Cc:To:From:Sender:Reply-To:Content-Transfer-Encoding: Content-ID:Content-Description:Resent-Date:Resent-From:Resent-Sender: Resent-To:Resent-Cc:Resent-Message-ID:List-Id:List-Help:List-Unsubscribe: List-Subscribe:List-Post:List-Owner:List-Archive; bh=qPlOJD8rmf8KH3iSmnAezWhxFsoju41PSmM+AJ01hUo=; b=XzSAkE71xc79h4nuUFBmbUJOjr BnuRFXw7J+PugfHMLPWLsHa2qQyvHRFHesyEF3QOVSDEqdpRIHcHPE0InT8P6THn4b4MpBdjQGRIo Tv8Lst23HdBYDZ47I51KFRLxKLXGOZssbHaJ2aul0ZUDljCVb9pyQwgyERboF1YQAft8=; Received: from cm-84.212.202.86.getinternet.no ([84.212.202.86] helo=xo) by quimby with esmtpsa (TLS1.3:ECDHE_RSA_AES_256_GCM_SHA384:256) (Exim 4.92) (envelope-from ) id 1k6tqY-0006nu-LZ; Sat, 15 Aug 2020 12:55:37 +0200 From: Lars Ingebrigtsen To: Eli Zaretskii Subject: Re: bug#34476: fluffy whitespace in the mode-line, despite it running off the screen References: <87lg2icx3u.fsf@jidanni.org> <87eeoi7un0.fsf@gnus.org> <87a6z67t7p.fsf@gnus.org> <83364y8ze0.fsf@gnu.org> <878seq8yzo.fsf@gnus.org> <83y2mq7jk7.fsf@gnu.org> <87mu367iue.fsf@gnus.org> <83sgcy7ebz.fsf@gnu.org> <87wo295wob.fsf@gnus.org> <83364x79jl.fsf@gnu.org> <83zh755udw.fsf@gnu.org> <87k0y94c8p.fsf@gnus.org> <83sgcx5mbm.fsf@gnu.org> <87tuxdxly3.fsf@gnus.org> <83r1sh5gjc.fsf@gnu.org> <87d040w3av.fsf@gnus.org> <83ft8v6hh7.fsf@gnu.org> <83sgcu4kz2.fsf@gnu.org> <83lfihld38.fsf@gnu.org> <83wo20jnwq.fsf@gnu.org> Date: Sat, 15 Aug 2020 12:55:33 +0200 In-Reply-To: <83wo20jnwq.fsf@gnu.org> (Eli Zaretskii's message of "Sat, 15 Aug 2020 11:47:49 +0300") Message-ID: <87zh6wyy8q.fsf@gnus.org> User-Agent: Gnus/5.13 (Gnus v5.13) Emacs/28.0.50 (gnu/linux) MIME-Version: 1.0 Content-Type: text/plain X-Spam-Report: Spam detection software, running on the system "quimby.gnus.org", has NOT identified this incoming email as spam.

Hm... I think the main use case for squeezing isn't really removing spaces from individual strings, but consider the entire resulting mode line as a whole. We end up with too-spacey mode lines, often, because we have formats that may or may not display something, but we still have spaces surrounding that element. > If this is not acceptable, then we will have to go back to your > original proposal of using Fformat_mode_line Yeah, I think that may be the way to go. > (although I'm still unhappy with doing that, as we had over the years > quite a few complaints that the result is not exactly identical to the > displayed mode line).

If someone modifies the mode-line face to use a font of a different size, or even has enough wide characters there to violate the "1 character = 1 column" assumption, that test will produce either truncated mode-line string or will unnecessarily squeeze spaces from it. I understand the difficulty of doing TRT, but perhaps we should at least document this limitation, so that users don't expect too much from this feature, and we don't get bug reports that will be hard to fix?

Yup. I was also not quite sure of the selected_window itself -- can the mode line be updated while another window is selected? But I tried various scenarios, and I couldn't get it to pick the wrong window to do the computation on. So perhaps that bit is OK? > I understand the difficulty of doing TRT, but perhaps we should at > least document this limitation, so that users don't expect too much > from this feature, and we don't get bug reports that will be hard to > fix?

The function display_mode_line doesn't produce the updated mode-line contents for the selected window, it produces it for the window passed as its first argument W.
