'window-prev-buffers' lists a buffer iff it has been displayed before
in the argument window. 'buffer-list' does something similar for its
argument frame but in principle does not care about whether a buffer
has been displayed already. So you have to decide what the tab-line
should do. Just an example: Should 'bury-buffer' affect a tab-line
and if so how?

Indeed. If you do care about yet undisplayed buffers, then such a
function might be needed.

Perhaps we should allow customization of the buffer order on the tab line, but I think the default order should not change when one switches buffers.

We have to ask Martin > is it possible to keep the original order in window-prev-buffers list. No. The aim of 'window-prev-buffers' (and 'window-next-buffers') is to make navigation between the buffers shown in that window reliable. So 'window-prev-buffers' is kept in a "most recently shown in that window first" order. Browser tabs are usually ordered by their creation time which has no relationship to what has been actually shown. You can create a new browser tab and then remove it without ever visiting the corresponding link. OTOH a buffer listed in 'window-prev-buffers' has been shown in that window at least once. After C-x 2 the new window has just one element in that list, the buffer it shows. The (here defunct) tab mix plus had a number of ways to affect the (dynamic re-)sorting of tabs including the positioning of a new tab wrt the currently active one.

But Firefox auto-scrolls the tab bar to the current tab.

AFAIU, there are several alternatives of how to go about the arrow buttons that hscroll the tab-line: . Always display both of them, but make one or both of them do nothing when scrolling in that direction makes no sense. . Display one arrow on the left and another on the right, and decide whether or not to display the right one in display_mode_line, depending on whether you hit (last_visible_x - arrow_width) while producing glyphs. . Add a new function, exposed to Lisp, to provide indication for whether the right arrow will be needed, then use a proper tab-line-format to actually display the arrow. It sounds like you decided to use the last alternative, but did you consider the other two? The first one sounds the easiest to me. the last one has a disadvantage that it does the tab-line processing twice, once to determine whether the right arrow is needed, and then again to actually display the tab-line. Also note that adding the right arrow will leave less screen estate for the tabs, so you need to account for this somehow in your decision whether that arrow is needed, lest displaying the arrow will make yet another tab partially visible. If you want to implement the last one, then you need a function that calls display_mode_line and returns a truncation indication depending on the state of it.glyph_row->truncated_on_right_p. The simplest way to achieve that is to add a new argument to display_mode_line, which, when non-NULL, will be a pointer to the flag where to return to the caller the truncation indication; then make display_mode_line set that flag according to the truncated_on_right_p flag. Let me know if the above makes sense, or if you have more questions.

To get the ordinal number of the current tab is trivial indeed, but when due to the large number of tabs preceding the current tab on the left side from it, it gets pushed off-screen behind the right window edge, we need to set the window parameter for the number of hscrolled tabs to such number of tabs that will reduce the length of displayed tabs on the left side from the current tab, so it becomes visible again. C code is only need to calculate the number of tabs to cut on the left side from the current tab to make it visible.

If we arrive at the conclusion that using the tab numbers, as I suggest above, is unworkable, then it would make sense to search it by walking the glyphs. I don't think it will be hard, let alone impossible, but let's first see why not do this in Lisp. And btw, why do you need to "find the current tab"? for what feature? Thanks.

And since the 'struct it' you pass to it is unrelated to what display_mode_line used, the value you print has no relation to what happens inside display_mode_line, nor with the actual flags of the glyph row produced by display_mode_line for displaying the tab-line. I verified in the debugger that when the tab-line is longer than the window width, the truncated_on_right_p flag of the tab-line's glyph row is always set, no matter how I resize the frame. (Given what I write below, this is not really important; I just wanted to point out your mistakes for the future.) > @@ -24984,7 +25018,10 @@ display_mode_line (struct window *w, enum face_id face_id, Lisp_Object format) > it.glyph_row->full_width_p = true; > it.glyph_row->continued_p = false; > it.glyph_row->truncated_on_left_p = false; > - it.glyph_row->truncated_on_right_p = false; > + > + /* Currently only tab-line needs truncation detection. */ > + if (face_id != TAB_LINE_FACE_ID) > + it.glyph_row->truncated_on_right_p = false; Here's the thing: I thought that you wanted the truncation indications to be displayed on the fringes, like we do with text-area lines. This is why I started talking about truncated_on_right_p flag: this flag is used by fringe.c to decide where to display the truncation bitmaps. But tab-line.el handles the hscrolling and truncation of tab-lines entirely in Lisp, and displays the hscrolling arrows by itself. So you don't need the truncated_on_right_p flag at all, and might as well revert the above change -- it has no effect for tab-line display the way that you implemented it. I now understand that you thought you needed this flag for finding the current tab, and only for that. I'm not yet sure that is true, see my other message. If it turns out I'm wrong, we can then return to this issue and discuss whether and how you need to cause this flag to be set.

Can you elaborate how > you intended to search for the current tab? We need to detect whether the current tab is before the right truncation point (so it is visible), or after the truncation (so the current tab is not visible). It seems searching for the current tab is not possible in the glyph matrix, because when the current tab is after the truncation point, then its glyphs are not produced. Then the code for searching the current tab should be similar to display_string but without producing glyphs.

Please try with this patch to resize the frame right edge until the edge
is between tabs, then it outputs "truncated_on_right_p=0" whereas
when the truncating frame edge is not between tabs then it outputs
"truncated_on_right_p=1"

Can you cook up a simple recipe where the truncation bitmaps don't appear, and also show the patch you used not to reset those flags? I'd like to look into what happens in the code in that case. > I don't want to modify display_string to take the tab-line > into account because more logic for searching the current tab > needs to be implemented anyway. Searching the current tab and displaying truncation indicators are two separate tasks that don't necessarily need the same (or even similar) code.

If you don't want the display code to produce glyphs, you should arrange for it->glyph_row to be a NULL pointer. See the call to init_iterator inside format-mode-line to understand how this is done. That function has the same problem as what you describe above.

I tried to not reset these flags only for the tab-line, and indeed
when the tab-line is truncated, then truncated_on_right_p is true
most of the time, but not always. It's false when the tab-line
is truncated between tabs.
AFAIU by looking at 'display_string', it looks like this has something
to do with whitespace between tabs as this comment explains:
/* Add truncation mark, but don't do it if the line is
truncated at a padding space. */
I don't want to modify display_string to take the tab-line
into account because more logic for searching the current tab
needs to be implemented anyway. So maybe better to copy code from
display_string to a new function tab_visible_in_tab_line,
and beside detection of truncation also add more code to detect
a situation when the current tab is not visible due to truncation.
One thing that I don't understand where a function similar to
display_string will produce glyphs? It should not touch the
real tab-line. It should only check if the produced glyphs
push the current tab out of view.

These flags are reset because display_mode_line forcibly resets them:
it.glyph_row->full_width_p = true;
it.glyph_row->continued_p = false;
it.glyph_row->truncated_on_left_p = false;
it.glyph_row->truncated_on_right_p = false;
I think you will find that before the last two lines are executed, the
truncated_on_right_p flag is set for the tab-line in your example.
I think we need to make a change there to not reset the last 2 flags
when we are displaying the tab-line. (The full_width_p flag should
still be set, because we don't want margin areas on the tab-line.)

I'm still trying to understand why truncation flags are not set in the tab-line.
Test case:
0. emacs -Q
1. M-x global-tab-line-mode RET
2. C-x b 01234567890123456789012345678901234567890123456789 RET
more buffers with long names might be needed
to cause the tab-line truncation
3. M-x dump-glyph-row RET
shows no truncation:
Row Start End Used oE><\CTZFesm X Y W H V A P
==============================================================================
0 0 0 111 110000000000 0 0 677 16 0 12 9
i.e. the columns '>' ('row->truncated_on_right_p')
and '<' ('row->truncated_on_right_p') both have values '0'.
Is this a bug? Or maybe there is another way to detect tab-line truncation
in the glyph matrix?

There are two related but separate features: scrolling and auto-scrolling. Scrolling is implemented now and installed. It provides UI with buttons, commands, and mouse-wheeling. Auto-scrolling could be implemented as well for user convenience: like when auto-hscroll-mode is enabled, the tab-line could do the same - when due to the long row of tabs, the current tab gets pushed over the right edge outside of the screen, then the tab-line could be automatically scrolled horizontally to make the current tab visible. This could be implemented by setting the right value to the new window parameter tab-line-hscroll, and it will bring the current tab back to the view. The main problem in implementing auto-scrolling is how to detect the situation when the current tab is not visible. Maybe by implementing a function like pos-visible-in-window-p, but named tab-visible-in-tab-line?

This is so overwhelming that I'm still struggling with understanding the
details of the display engine. If hscrolling was already implemented
for the header-line, we could just copy the existing solution to the
tab-line.
So I looked how packages cope with the requirement of keeping hscrolling
of the header-line in sync with hscrolling of the buffer, and found that
the 'proced' package uses so simple solution that we could just do
the same. This is what it does:
(defun proced-header-line ()
"Return header line for Proced buffer."
(list (propertize " "
'display
(list 'space :align-to
(line-number-display-width 'columns)))
(if (<= (window-hscroll) (length proced-header-line))
(replace-regexp-in-string ;; preserve text properties
"\\(%\\)" "\\1\\1"
(substring proced-header-line (window-hscroll))))))
i.e. it just cuts scrolled content from the beginning.
Adapting the same idea to the tab-line provides the workable and
reliable solution with just a dozen lines of Lisp code. You can
evaluate this, and everything works smoothly:
(advice-add 'tab-line-format :around
(lambda (orig-fun)
(let ((tabs (funcall orig-fun))
(hscroll (window-parameter nil 'hscroll)))
(if hscroll (nthcdr hscroll tabs) tabs)))
'((name . tab-line-format-hscroll)))
(defun tab-line-hscroll (&optional arg window)
(let* ((hscroll (window-parameter window 'hscroll)))
(set-window-parameter
window 'hscroll (max 0 (min (+ (or hscroll 0) (or arg 1))
(1- (length (funcall tab-line-tabs-function))))))))
(defun tab-line-hscroll-left (&optional arg mouse-event)
(interactive (list current-prefix-arg last-nonmenu-event))
(tab-line-hscroll arg (and (listp mouse-event) (posn-window (event-start mouse-event))))
(force-mode-line-update))
(defun tab-line-hscroll-right (&optional arg mouse-event)
(interactive (list current-prefix-arg last-nonmenu-event))
(tab-line-hscroll (- (or arg 1)) (and (listp mouse-event) (posn-window (event-start mouse-event))))
(force-mode-line-update))
(global-set-key [tab-line mouse-4] 'tab-line-hscroll-left)
(global-set-key [tab-line mouse-5] 'tab-line-hscroll-right)
(global-set-key [tab-line wheel-up] 'tab-line-hscroll-left)
(global-set-key [tab-line wheel-down] 'tab-line-hscroll-right)
Thus mouse-wheel hscrolls the tab-line exactly like mouse-wheel
hscrolls tabs in Firefox.
Also these two commands can be used via M-x, and can be bound
to some key that could used via a transitive keymap, e.g.
some prefix initiates a key sequence, then consecutive
<right> keys continue hscrolling.
Later advice-add will be moved into the body of tab-line-format.

Either that, or bind the click on the fringe to a command that looks
at posn-area of the click event, and scrolls the tab-line of the area
is tab-line.

That would prevent using the drag events for something else, like
reordering the tabs. It is also not what other applications do,
right?

That could be an additional feature, but it cannot be the only one, I
think, because some mice have no wheel.

I think you will need a new function. A tab-line is generated from a
Lisp string, and we don't have code for hscrolling screen lines
produced from strings (as opposed to from buffer text).
The general idea is to identify the first (leftmost) tab you want to
be visible, and then make changes in display_mode_line to start
display from that tab. I think the first part is the more complex of
these two. format-mode-line shows an example of how to generate
display derived from Lisp and C strings without displaying anything;
you could use that for finding the X coordinate (in it.current_x) of
the beginning of the Nth tab's button. Each click on the right fringe
increases N, each click on the left decreases it. The X coordinate
you compute is the value to use for it.first_visible_x in
display_mode_line.
I hope this makes enough sense to get you going. If not, please ask
more specific questions.
Thanks.

Trying to click on truncation arrows in fringe bitmaps of buffers signals:
<right-fringe> <mouse-1> is undefined
So we need to bind <mouse-1> to a tab-line scrolling command
for [tab-line right-fringe] keymap?
Or maybe the tab-line could be dragged like dragging the
horizontal scroll bar in horizontal-scroll-bar-mode?
Or mouse-wheel could scroll the whole tab-line horizontally
instead of switching tabs like it does now?

I thought that granularity should be wider: scrolling by the window width,
like 'C-x >' ('scroll-right') does, where default is window width minus 2.
But maybe tab-button granularity is fine. The only problem is that
I still studying the code to understand where to begin. Could you suggest
in what function to implement all this scrolling?

There's an important difference, I think: you want to scroll the tab-line in tab-button granularity, not one character at a time. But the principle and the main idea is the same, yes.

It seems before implementing this, first we need to decide what UI we could provide. This decision affects a set of commands that needs to be implemented for tab-line hscrolling. One variant is to allow dragging the tab-line by mouse where dragging to the left will scroll the tab-line to the left. But actually no web browser implements this behavior, they use dragging to move a tab to other place. So maybe better to have two arrow buttons: clicking on the left arrow will hscroll to the left. Then we need two commands implemented in C: 'tab-line-scroll-left' and 'tab-line-scroll-right'. And later to add some keys like 'C-x >' bound to 'scroll-left'. These commands could work for the tab-line like hscrolling in the buffer works when 'auto-hscroll-mode' is 'current-line'. Also their ARG could be like in 'scroll-left' where the default ARG is window width minus 2.

Also note that when a screen line (a.k.a. "glyph row") is hscrolled, its display doesn't starts when it.current_x is zero, it starts when it.current_x is it.first_visible_x.

Thanks for the explanation. One thing that I still don't understand is how to find the exact position in the mode-line string where it's truncated. For example, in the string "...abc|xyz", the part until "abc" is visible, but the rest of the string is truncated, so "xyz" is not visible. How to find this position where truncation occurs? Actually, it seems I found it, it's it.last_visible_x. Is this correct?

Variable sized tabs can be a pain. When you want to kill a row of tabs by clicking on the "x" you have to move the mouse in between. martin

Thanks. > But the first question popped up quickly: I don't understand > how to detect the situation where the tab-line is truncated? The situation that it's truncated, or the situation that it _needs_ to be truncated, i.e. the next tab doesn't fit on the line? If the former, the glyph_row->truncated_on_right_p flag should be set. You can see it being set in display_string, which is called from display_mode_line. If you mean the latter, then look how the truncated_on_right_p flag is being set in display_line or in other similar display functions, like display_tab_bar_line. > And how to find the tab that is visible partially? > Especially when the font is variable-pitch. I think you will need to walk the glyphs in the tab-line looking for the last glyph whose character position has the property you put on tabs in tab-line (as specified in by tab-line-format). Or maybe tab-line-format should put some special property on the last glyph of a tab, so that you could look for it more easily? Let me know if the above is not detailed enough to get you off the ground. > What I'm trying to do is to hide leftmost tabs one by one until > the current tab on the rightmost side becomes completely visible. That will work, but it's inefficient. Once you know the number N of pixels are needed to show the tab you want to unhide, just walk the glyphs of the tabs from the left edge until you find the first tab whose horizontal position M is greater or equal to N. then set it->first_visible_x to that number M and display the tab line.

I've started with implementing hscrolling for window tab-line because this is needed for both graphical displays and TTY. But the first question popped up quickly: I don't understand how to detect the situation where the tab-line is truncated? And how to find the tab that is visible partially? Especially when the font is variable-pitch. What I'm trying to do is to hide leftmost tabs one by one until the current tab on the rightmost side becomes completely visible. Please advise.

same reason why currently the menu-bar is one-line, the tab-bar should be one-line on TTY frames. For the same reason the header-line is one-line too, so the tab-line should be one-line too. This means that we still need to find a solution how to scroll tabs on one line. > Add hscrolling support for pseudo-windows, I think. It could start > with a specialized function to hscroll just the tab-bar, then the code > could just start displaying the tab-bar window starting at a button > that is not necessarily the first one. Since it's not clear how to do refactoring for multi-line tab-bar on TTY and for multi-line tab-line, I'm going to explore the hscrolling option. >> Does hscrolling depend on the position of point so point should be >> moved to the current tab to center other tabs around it? > > I was talking about the truncation glyphs and clicking on them, not > about automatic hscrolling when point gets too close to the window > edge. I started to implement adding truncation arrow buttons at both sides of the one-line tab-bar, clicking on them will hscroll the tab-bar. >> Also I tried to insert newlines in the tab-bar string, without success. > > Not sure I understand this part.

Firefox provides both options at the same time: two arrow buttons to hscroll tabs, and one dropdown button to pop up a menu of tabs. It's easy to implement both. --=-=-=--

We could make display_tab_bar_line work on TTY frames, but then the question becomes why have a separate display_tab_bar function for TTY frames instead of making redisplay_tab_bar support TTY frames as well.

Add hscrolling support for pseudo-windows, I think.

The code could be small, but it will probably lead us down a rabbit hole of more discussions, bug reports and feature requests, yet more discussions, etc. I'd like to stabilize this feature soon at some reasonable point and leave the rest to future releases.

Here is comparison of colors (at the bottom is Chromium): Chromium has additional visual queues for the current tab (as do other browsers), while we don't. So the color is much less important for the browsers than it is for us, because in Emacs the color is currently the _only_ indication of the current tab.

The current value of 1.1 produces too large tab names. Btw, as long as we are optimizing the tab-bar appearance: I think the choice of the colors of the current and non-current tabs should be reversed: the lighter color is more appropriate for "inactive" than the darker one. Alternatively, use some non-gray color for the current tab (I personally think these gray colors are too dull). Thanks.

I tried to customize the mode-line face to a variable-pitch font, and indeed glyphs not only for SPC, but for 1-character indicators '-' and '*' that toggle e.g. writable/modification states or switch coding, are so thin that it's hard to click them with the mouse.

BTW, is there a reason why the mode line doesn't use a variable-pitch font? I tried a variable-pitch font for tab bars, and it looks good and makes tab widths smaller, so more tabs fits into the tab-bar. But maybe non-monospace fonts might complicate calculation of various text lengths when trying to fit tabs into the tab-bar.

Or don't truncate but allow scrolling tabs with mouse wheel; Yes, this could work as well (but scrolling should be possible not only with the mouse). The implementation could simply hscroll the tab-bar window, including automatic hscrolling when the current tab is far from the leftmost one. Maybe this alternative is the easiest one. The only difficulty here is with TTY frames. Thanks.

What are the possible options? 1. Use something like word-wrap in the tab-bar to wrap to the second line non-broken tabs at tab boundaries; 2. Disable wrapping to the second line since it's not supported in -nw; 3. Then truncate tab names to fit all tabs into the first line; 4. Or don't truncate but allow scrolling tabs with mouse wheel;
