Fixes#3953Fixes#3284
This fixes two issues. In fixing one issue, the other became apparent so
I fixed both in this one commit.
The first issue is that on macOS, the `open` command should take the
`-t` flag to open text files in a text editor. To do this, the `os.open`
function now takes a type hint that is used to better do the right
thing.
Second, the order of the paths that we attempt to open when editing a
config on macOS is wrong. Our priority when loading configs is well documented:
https://ghostty.org/docs/config#macos-specific-path-(macos-only). But
open_config does the opposite. This makes it too easy for people to have
configs that are being overridden without them realizing it.
This commit changes the order of the paths to match the documented
order. If neither path exists, we prefer AppSupport.
Some opener commands (like macOS's open) finish immediately after
running, while others (xdg-open) do not, staying alive until the
application that was opened itself terminates.
For now, we explicitly state whether or not we should wait for a
command. Eventually we may want to do something more generic (e.g. wait
for some predetermined amount of time and if the process does not
complete, give up without collecting stderr).
This gets `zig build -Dtarget=aarch64-ios` working. By "working" I mean
it produces an object file without compiler errors. However, the object
file certainly isn't useful since it uses a number of features that will
not work in the iOS sandbox.
This is just an experiment more than anything to see how hard it would be to
get libghostty working within iOS to render a terminal. Note iOS doesn't
support ptys so this wouldn't be a true on-device terminal. The
challenge right now is to just get a terminal rendering (not usable).
