This slightly changes the open and term command to be similar with the
Quit action, where the buffer or pane is replaced after the prompts are
completed if "n" wasn't pressed after the 1st prompt.
Copy build constraints in actions_other.go to terminal_unsupported.go,
to avoid maintaining separate build constraints that are similar with
terminal_supported.go.
Support terminal emulation on platforms below:
- Solaris
- NetBSD: Supported in creack/pty since v1.1.12
- OpenBSD with GOOS != amd64
- Other architectures are supported now in creack/pty
- extract the open logic into `openFile()` and return a `wrappedFile`
- extract the closing logic into `Close()` and make a method of `wrappedFile`
- rename `writeFile()` into `Write()` and make a method of `wrappedFile`
This allows to use the split parts alone while keeping overwriteFile() as simple
interface to use all in a row.
Setting options directly in (h.)Buf.Settings without calling SetOption() or
SetOptionNative() is generally not the best idea, since it may not
trigger the needed side effects.
In particular, after https://github.com/zyedidia/micro/pull/3343,
directly setting `diffgutter` and `ruler` causes them not being tracked as
locally overridden per buffer, so if we run the `reload` command,
it unexpectedly replaces them with the default ones.
In `ReloadSettings()` the `filetype` can change upon globbed path given by
the `settings.json` or by identifying a different `filetype` based on the
file name given or pattern present inside the file.
To prevent further recursion caused by checking the `filetype` again, its
processing stops here and isn't considered in `DoSetOptionNative()`
once again where the callbacks are usually triggered.
Like in NewBuffer(), we need to update glob-based local settings
before updating the filetype, since the filetype itself may be among those
glob-based local settings.
* `UpdatePathGlobLocals()`
* to apply the settings provided within e.g. "/etc/*": {}
* `UpdateFileTypeLocals()`
* to apply the settings provided within e.g. "ft:shell": {}
We don't need to call `InitLocalSettings()` twice any longer.
