This patch adds a new config option, font-size-adjustment.
It lets you configure how much the font size should be
incremented/decremented when zooming in or out (ctrl-+, ctrl+-).
Values can be specified in points, pixels or percent.
Closes#1188
* Both double and single quotes are recognized. There’s no difference
in how they are handled.
* The entire string must be quoted:
- “a quoted string” - OK
- quotes “in the middle” of a string - NOT ok
* Two escape characters are regonized:
- Backslash
- The quote character itself
Initialize the global ‘do_syslog’ variable to false. This ensures any
log calls done before log_init() has been called (e.g. unit tests)
doesn’t syslog anything.
As a side effect, such log calls no longer open an implicit syslog
file descriptor; this is how this “bug” was found: valgrind detected
an unclosed file descriptor at exit.
Finally, completely disable syslogging if log-level is “none”.
Before this patch, hyperlinked cells were tagged with the “URL”
attribute (thus instructing the renderer to draw an
underline) *before* the grid was snapshot.
When exiting URL mode, the cells were once again updated, this time
removing the URL attribute.
But what if an escape sequence had modified the grid _while we were in
URL mode_? Depending on the sequence, it could move cells around in
such a way, that when exiting URL mode, the affected cells weren’t
updated correctly. I.e. we left some cells with the URL attribute
still set.
The fix is simple: tag cells in the snapshot:ed grid only (which isn’t
affected by any escape sequence received while in URL mode). Not in
the *actual* grid (which _is_ affected).
This fixes an issue where selections in the scroll margins were not
detected correctly. This meant they weren’t canceled as they should
have been, which in turn caused a visual glitch where text appeared to
be selected, but were in fact not.
Before this patch, a user-set line-height was increased/decreased by
the exact same amount of pt’s as the font(s).
This means, that when there’s a large discrepancy between the
line-height and the font size, the proportion between the line’s
height and the font size will change as we increase or decrease the
font size.
This patch changes how the line height is adjusted when the font size
is incremented or decremented. We calculate the difference, in
percent, between the primary font’s original (default) size, and its
current size, and then apply that to the configured line-height.
Closes#1218

That's 17 lines of output that are *mostly* useless for most use
cases. I might understand having this output during the project's
startup, when it's helpful for diagnostics, but now Foot just mostly
works everywhere, and I've never had a use for any of that stuff in
the (arguably short) time I've been using Foot so far.
And if I do, there's the `--log-level` commandline option to tweak
this. At first, I looked at tweaking the log level through the config
file. But as explained in this issue:
https://codeberg.org/dnkl/foot/issues/1142
... there's a chicken and egg problem there that makes it hard to
implement and possibly confusing for users as well.
There's also the possibility for users to change the shortcut with
which they start foot, for example a `.desktop` file so that menu
systems that support those start foot properly. But that only works in
that environment, and not through the so many things that will just
call `foot` and hope it will do the right thing.
In my case, I have `foot` hardcoded in a lot of places now, between
sway and waybar, and this is only going to grow. Others have suggested
adding the flag to a $TERMINAL global variable, but that won't help
.desktop users.
So, instead of playing whack-a-mole with the log levels, just make it
so that, by default, foot is silent. This is actually one of the
[basics of UNIX philosophy][1]:
> Rule of Silence: When a program has nothing surprising to say, it
> should say nothing.
And yes, I am aware I am severely violating that principle by writing
a way too long commit log for a one-line patch, but there you go, I
figured it was good to document the why of this properly.

If an output has a bogus physical width or height, the DPI can become
so high that the cell width/height is too large for
pixman_image_fill_rectangles(), resulting in a crash in pixman_fill().
Since it doesn’t make any sense to use a DPI that is obviously bogus,
don’t. Force it 96 instead.
When drawing a block cursor using inversed fg/bg colors, we didn’t
strip the alpha from the background color. This meant that the text
"behind" the cursor was rendered with transparency. If alpha was set
to 0, the text was completely invisible.
We should never apply alpha to the text color. So, detect this, and
force alpha to 1.0.
Normally, when selecting the cursor’s color, we don’t really know
_where_ the background color is coming from (or more accurately,
_what_ it is).
However, the *only* background color that can have a non-1.0 alpha is
the *default* background color.
This is why we can ignore the bg parameter, and use term->colors.fg/bg
instead.

The Appstream metadata file introduced in commit
335612cfa4
has been submitted as licensed under the CC0-1.0 license. People
generally use the CC0-1.0 to put the file in the "public domain", but
this isn't actually possible in lots of countries, so the file ends up
being licensed under CC0's fallback permissive license; unfortunately,
the fallback license contains some terms that are seen as problematic to
some (notably, Fedora has recently decided to consider the license
pretty much non-free).
As foot is already MIT-licensed, and since this license is in the list
of allowed [metadata licenses], this patch changes the license of the
metadata file from CC0-1.0 to MIT.

On my system, GCC doesn't output its name when passing the --version

As the Free Software Foundation is unlikely to write another compiler, I
think that searching for the foundation's name instead of GCC is a good
enough fix (and I'm almost sure we wouldn't be the first ones to do so).
This used to work because we never free:d any of the rows. Now
however, we do free (some of) them when reverse scrolling. This means
we can no longer re-use the rows between the two screens.
Closes#1196
Re-initialize the temporary ‘normal’ grid instance each time we
receive a configure event while doing an interactive resize.
This way, window content will not be "erased" when the window is first
made smaller, then larger again.
And, if the viewport is up in the scrollback history, increasing the
window size will reveal more of the scrollback, instead of just being
black.
The last issue is the cursor; it’s currently not "stuck" where it
should be. Instead, it follows the window around. This is due to two
things:
1) the temporary grid we create is large enough to contain the current
viewport, but not more than that. That means we can’t "scroll up", to
hide the cursor.
2) grid_resize_without_reflow() doesn’t know anything about
"interactive resizing". As such, it will ensure the cursor is bound
to the new grid dimensions.
I don’t yet have a solution for this. This patch implements a
workaround to at least reduce the impact, by simply hiding the cursor
while we’re doing an interactive resize.
When determining whether or not to cancel a selection (due to it, or
part of it, being "scrolled out"), we assumed the scrollback was full.
This patch changes the implementation to compare the scrollback
relative selection coordinates with the scrollback relative
end-of-the-scrollback coordinates.
This ensures *everything* in the circular scrollback history, after
the bottom of the screen, is either NULL rows, or belong to the
scrollback *history* (as opposed to the future history).
This fixes an issue when calculating the scrollback start, which for
example would trigger a crash when moving the viewport (i.e. scrolling
with the mouse, or PgUp/PgDown).
Closes#1190
When we try to resize a sixel past the current max height, we set
col > image-width to signal this.
This means ‘width’ could be smaller than ‘col’. When calculating how
many sixels to emit in sixel_add_many(), we didnt’ account for this.
The resulting value was -1, converted to ‘unsigned’. I.e. a very large
value. This resulted in an assert triggering in sixel_add() in debug
builds, and a crash in release builds.
But also, more importantly, logical fixes:
* Stash the number of new scrollback lines the stashed ‘normal’ grid
should be resized *to*.
There’s also a couple of performance changes here:
* When doing a delayed reflow (tiocswinsz timer), call
sixel_reflow_grid(term, &term->normal) - there’s no need to reflow
sixels in the ‘alt’ screen.
* When doing a delayed reflow, free all scroll damage. It’s not
needed, since we’re damaging the entire window anyway.
* Use minimum size for the temporary ‘normal’ grid (that contains the
current viewport). We just need it to be large enough to fit the
current viewport, and be a valid grid row count (power of 2). This
just so happens to be the current ‘alt’ grid’s row count...
