Rather than hardcode a fixed default value in the config crate, define
the default as optional and leave it to the font crate to compute
the value.
This is a step towards allow introducing system dependent GUI related
code to resolve/understand the title font: we can't put that directly
in the config crate.
Add `get_foreground_process_name` to both Pane and the lua wrapper.
Add `foreground_process_name` and `current_working_dir` fields to
`PaneInformation`. In order for those to be dynamically fetched,
switch the lua conversion for `PaneInformation` to be a UserData
with field access methods. It's a little more verbose but allows
us to lazily compute these two new fields.

This commit expands quick select mode so that you can trigger it
with distinct sets of patterns (eg: urls on one key assignment,
hashes on a different key assignment), different alphabets,
and lastly, the option to perform a different action from
the default copy action.
You can pair this with `action_callback` to run lua code to
do something with the selected text.
This commit also adds `wezterm.open_with`, a helper function
for opening documents/URLs.

The label dedup code has panicked on me a couple of times.
I managed to capture the line number, so this commit aims to
capture some state to try to understand what's going on,
and importantly, to avoid the actual panic part.

permits iTerm2 images to be drawn anywhere on screen without
scrolling the cursor, including the bottom row.
Also included is a check in fcwrap.rs to_range_set(), without which
was causing a panic at runtime due to subtraction from unsigned
leading to overflow.
This helps us correctly set the size of the image cell
for the case where we have a partial cell at the right/bottom
edge of an image being mapped across cells.

Move away from the imprecise simple pow version and over to a
version that properly respects the linear and non-linear portions
of the curve.

On Windows, both EGL and MESA render modes were too dark.
After a bit of hunting around what I found made EGL and MESA
consistent with my default nVidia GPL rendering was:
* Tell glium that our shader outputs srgb
* Add explicit gamma conversion from linear to srgb in the shader
AFAICT, that shouldn't be required, but it seems as though something
deep in glium really wants to apply some kind of gamma conversion,
and it seems to select the wrong kind unless we set things explicitly
to SRGB.
There are some people complaining about this in
https://github.com/glium/glium/issues/1615.
I actually tried to move entirely aware from the glium srgbtexture2d
type in the hope of having explicit control over the gamma, but the
issue is in what happens to the outputs rather than the inputs.
It appears to me as though the text now looks slightly less
intense, so I think this may be what we need for the gamma issue
in https://github.com/wez/wezterm/issues/544 and potentially
also https://github.com/wez/wezterm/issues/1025

Adds some plumbing to allow the GUI to implement a download handler
and connect that up for iterm2 image/file transfers that have their
inline property set to false.
Previously we'd just log an error.
Now we will by default download the file to the user's download
directory.
This behavior can be turned off via the new `allow_download_protocols`
configuration setting.
File transfers can be initiated on a remote host via the
https://iterm2.com/utilities/it2dl script.
When the download completes, a toast notification is shown that will
open the file when clicked.

Remove special case for blocks where we switched it out for a blank
sprite and instead varied the cell background.
We now always render a matching cursor sprite as a separate layer
over the top of the text background color, but below the text
foreground layer.
This is preparing for https://github.com/wez/wezterm/issues/1432
Make bar/line cursors use the text foreground color when reverse
video cursors are enabled, per @VKondakoff:

Finally getting around to fixing this usability wart: this commit
changes the behavior of Window closing so that you can close a window
containing multiplexer panes without prompting and without killing
off those panes.
This is achieved through some plumbing:
* The mux can now advise Domains about an impending window closure,
giving them the opportunity to "do things" in readiness.
* The mux client domain informs the container ClientPane instances
to ignore the next Pane::kill call, which would otherwise inform
the mux server to kill the remote pane
* Pane:can_close_without_prompting now requires a CloseReason.
* ClientPane's can_close_without_prompting impl allows Window closing
without prompting on the assumption that the ignore-next-kill hack
above is working
refs: #848
refs: #917
refs: #1224
The mux client just returns a dummy reader, and some overlays
have panicking stubs: just allow for them to return None
instead of potentially spawning a useless thread.
Previously, we would only look at the `check_for_updates` config
on startup.
This commit adjusts the update checker logic so that we always
start it, and that we respect config reloads.
Only show the update window and/or generate a toast notification
is the current wezterm-gui process is the eldest of the set of
running wezterm-guis.
This avoids spamming the user with update information.

This code was partially replicating the initial window setup
where we didn't necessarily know the dpi, but in the context
where this is run, we do know the dpi for the window, so
let's consistently use that number throughout.

The intent is to workaround what appears to be an i3 bug.
Not totally sure this is a good change, but let's try it!
Might also help with an issue on macos.

This moves away from using special block glyphs for the lines and
just draws lines directly.
In addition, since these lines are no longer constrained to available
glyphs or glyph boundaries, we can now render lines that cross when
there are a mix of horizontal and vertical splits, which looks a
bit nicer.
refs: #1256
Assuming that the window config reloaded hook doesn't actually change
anything, this will avoid a cycle where we keep triggering the hook
over and over.
This is a fairly far-reaching commit. The idea is:
* Introduce a unicode_version config that specifies the default level
of unicode conformance for each newly created Terminal (each Pane)
* The unicode_version is passed down to the `grapheme_column_width`
function which interprets the width based on the version
* `Cell` records the width so that later calculations don't need to
know the unicode version
In a subsequent diff, I will introduce an escape sequence that allows
setting/pushing/popping the unicode version so that it can be overridden
via eg: a shell alias prior to launching an application that uses a
different version of unicode from the default.
This approach allows output from multiple applications with differing
understanding of unicode to coexist on the same screen a little more
sanely.
Note that the default `unicode_version` is set to 9, which means that
emoji presentation selectors are now by-default ignored. This was
selected to better match the level of support in widely deployed
applications.
I expect to raise that default version in the future.
Also worth noting: there are a number of callers of
`unicode_column_width` in things like overlays and lua helper functions
that pass `None` for the unicode version: these will assume the latest
known-to-wezterm/termwiz version of unicode to be desired. If those
overlays do things with emoji presentation selectors, then there may be
some alignment artifacts. That can be tackled in a follow up commit.

It appears as though Menlo is the only font on macos to contain the
heavy ballot cross symbol, which is commonly used on macos (eg: in
`brew` output).
Our fallback list, despite starting with Menlo, didn't include menlo
itself in the candidates.
Furthermore, `ls-fonts` wouldn never see the result of the system
fallback resolution because it didn't know to try again, and was
using the list of handles from before the fallback.
This commit resolves all of these concerns.
refs: #849
Since we may have two different sizes/namespaces of fonts between
the title font and the main terminal font, we need to be a bit more
careful to pass down distinguishing font information when caching
glyphs.
In addition, I noticed that the advance for custom block glyphs
(eg: powerline!) weren't right in the tab bar. To resolve this,
when shaping, we skip using the glyph from the font and synthesize
a placeholder with the appropriate advance.
We were truncating the right-status text because we were passing
the padded number of cols for the tab bar, but since the tab bar
now exists outside the padding, that value was too small.
This commit introduces the `Dimension` type which allows specifying
a value in a variety of units; pixels, points, cells, percent.
`Dimension` needs contextual information to be evaluated as pixel
values, which makes resolving the value from the config slightly
more of a chore.
However, this type allows more flexible configurations that scale
with the font size and display dpi.

The previous commit was partially OK, but the main cause of
emoji being wonky was this bit of macos specific code that I
added ages ago.
Remove that hack and the portion of the code from the previous
commit that was working to undo it.
This should make the baselines consistent across all platforms.

Avoid accidentally scaling the tab bar when using IncreaseFontSize.
Use a "better" default title font based on the platform.
Avoid a gap between bottom of tab button and dividing line at
certain font sizes.
When split horizontally, selecting multiple lines at the top of the left
pane could paint a horizontal selection line all the way across the rest
of the terminal to the right hand edge.
Removes the dependency on knowing where the pane top/left position
is so that the line render routine could be used in more places.
Adjusts the tab bar and scroll bar positioning so that the tab bar
ignores window padding and is always flush with the top/bottom window
edge (full width as well), and that the scroll bar top/bottom respects
the tab bar position and height.
More of a "fix"; we use some heuristics based on the bearing
and glyph width to figure out if a sequence looks like a funky
ligature that moves left to render the glyph.
This may be prone to false positives, but the consequences are low:
when we think a glyph is part of a ligature, then rather than using
the cursor_fg color (which is typically black, or close to invisible),
we retain the normal text fg color.
This way the portion of the glyph outside of the cursor retains its
foreground color, and just the cell containing the cursor may have
a slightly funky fg color in the case where the heuristic was bad.
closes: #478
`use_fancy_tab_bar` switches to an alternate rendering of the tab
bar that uses the window_frame config to get a proportional
title font to use to render tabs, as well as rendering a few
additional elements to space out and make the tabs feel more
like tabs.
Computing the number of tabs doesn't respect the alternate font
at this time.
Formatted tab item foreground and background colors are also
not respected at this time.
refs: #1180
We now compute the cap-height from the rasterized glyph data.
Moved the scaling action of use_cap_height_to_scale_fallback_fonts from
glyphcache into the font resolver: when enabled, and we have data
about the baseline font and the font being resolved, then the resolving
font will be scaled such that the cap-height of both fonts has the same
pixel size.
The effect of this is that `I` glyphs from both fonts should appear to
have the same height.
Added a row of `I`'s in differing styles at the bottom of styles.txt
to make this easier to visualize.
refs: #1189
This is to handle situations such as some versions of the Terminus
bitmap font, where the individual bitmap strike sizes are broken
out across multiple individual files.
Font matching now passes down the nominal pixel height based on
the current DPI and font scale factor, and will use that to select
the font file that has the closest pixel size.
Previously, it would be potentially undefined which of the Terminus
font files would be selected.
