* feat: use CARGO_BUILD_TARGET_DIR env
When building in the presence of a CARGO_BUILD_TARGET_DIR, there is no
target dir created inside the repo, so copying to a location within the
local repo dir fails, hence we need to copy to the actual target dir
that is being used.
* fix: environment variable with correct name
Previously, we used `git describe --tags` to produce a version number
for non-released builds derived from the most recent tag + some info
such as the number of commits since that tag and then `g{HASH}`.
That always confuses people because the date portion at the front
looks old (it is typically the previous release) and the hash at
the end has that `g` in it.
This commit simplifies both the tag name used when making a release
and the computed version number take the date/time from the current
commit, and then append the hash. That way the version number always
corresponds to a commit.
This scheme doesn't help detect situations where the commit is
dirty, but I don't think the old one would have helped with that
either.
This commit implements the deprecated NSUserNotification bits needed
to be able to handle clicking on a notification and open our choice
of URL.
Ideally we'd use the newer UserNotifications framework, but that
requires code signing.
This commit moves a bunch of stuff around such that `wezterm` is now a
lighter-weight executable that knows how to spawn the gui, talk to
the mux or emit some escape sequences for imgcat.
The gui portion has been moved into `wezterm-gui`, a separate executable
that doesn't know about the CLI or imgcat functionality.
Importantly, `wezterm.exe` is no longer a window subsystem executable
on windows, which makes interactions such as `wezterm -h` feel more
natural when spawned from `cmd`, and should allow
`type foo.png | wezterm imgcat` to work as expected.
That said, I've only tested this on linux so far, and there's a good
chance that something mac or windows specific is broken by this
change and will need fixing up.
