The paths checked by `fn exists` are well-known Unix locations, and not
meaningful to check on Windows.
Provide an implementation of `fn exists` for Windows, which uses
`which.exe` to look for binaries, and use that to provide sane defaults
for Windows.
Git for Windows horribly mangles the configured binaries through a POSIX
`sh`-like environment even on Windows. We might be able to figure out
which `sh.exe` we would have to execute on Windows, but this is too
brittle. Windows users will have to use other mechanisms (like `$EDITOR`
and `$PAGER`) to configure their programs.
Command line parsing differs on Windows vs. POSIX compliant operating
systems (just consider the differences in handling `\` for paths vs. as
a marker for escape sequences). Thus, on Windows use `winsplit` to
split command arguments instead of `shlex` for Unix-like OSes.
`winsplit` is a small crate with no other dependencies.
This introduces a `PaintTarget`, that defines the stream an operation
uses to draw to (`stdout`, `stderr`, `sink`). It will be used in
subsequent commits to configure the new spinner.
As a library crate, it is bad to return such generic errors.
To get there, errors from `inquire` are downcasted.
This allowed to clean up the public interface of `radicle-term`, so that
it does also not leak the `inquire::InquireError` in its public API.
This is dead code that imports `anyhow`. On the way to removing the
dependency on `anyhow` from `radicle-term`, it just seems to be a good
idea to remove the cruft.
This way the Iterator::size_hint() function can be used by the
Extend::extend() implementation, which might safe reallocations for
the underlying buffer.

Symbols signaling status of a process and similar are duplicated in
three different crates. Also two different symbols to signal success are
used:
1. ✓ ( Check Mark, U+2713)
2. ✔ (Heavy Check Mark, U+2714)
Work against that by referring to `radicle-term` from the other crates.
This is morally a revert of 70fb0d3fef
while additionally getting to compile
`crates/radicle-term/src/editor.rs` on Windows.
To get the changes that were made on top of the revert, check
git diff 70fb0d3fef~1 <this commit> -- crates/radicle-term/src/editor.rs
There were reports of the inquire editor being unrealiable.
Provide a default message that informs the user of the `(e)`, `(enter)`, and
`(esc)` functionality.
Unfortunately, it is not possible to provide any message that is better
customised to each case, due to `inquire` requiring a `'a` lifetime on all its
inputs – this rules out providing any kind of `String` input.
The first paramter of `Editor::new` can already be used to provide more
contextual information. The second parameter is left configurable, but for now
`Editor::HELP` is used everywhere.
Introducing the new enum `TerminalFile` to model which standard stream
stream the terminal uses allows us to remove the dependency on `libc`
which does not build on Windows.
`radicle-term` includes quite a lot of rather "low-level" logic to spawn
the preferred editor of the user. In particular, this logic is
platform-dependent and only works on Unix-like platforms.
Also, `radicle-term` already depends on `inquire` which features an
editor prompt. It is a cross-platform solution to spawn the editor.
This commit changes the implementation of `Editor` to be a wrapper of
`inquire::Editor`, keeping the interface mostly intact.
Downsides:
- We cannot edit a file "in place" this way, instead we have to read
it, as `inquire` only supports editing temporary files. This can also
be viewed as a benefit, as we lessen the risk of corruption of these
files.
- `inquire::Editor` contains borrows, so it is quite cumbersome to
extend it with a custom mechanism for looking up the preferred
editor. The lookup logic was kept, but needs to be invoked by the
caller. In the future we might consider just using the logic provided
by `inquire` or requesting a change to `inquire`.
- The prompt is a bit strange. It does not show the current state of
the output, see <https://github.com/mikaelmello/inquire/issues/280>
and <https://github.com/mikaelmello/inquire/pull/271>.
The `radicle-signals` crate only supports Unix, so using it prevents
`radicle-term` to build on Windows.
Of course, this means that non-Unix platforms will not support any
signal handling at all, but at least we can build.
I learned that there is an implementation of a pager in
`crates/radicle-term/src/pager.rs`. It does not make sense to me to
maintain a pager in `heartwood`, this is too far from the core of what
we are trying to achieve and adds unnecessary maintenance burden. We can
allow ourselves to defer to the paging done by `git` or just call the
user's `$PAGER`. Even though falling back to unpaged output might not be
the nicest thing, I still prefer that over maintaining the pager.
It also was frustrating to me that the pager does not support things
like search (like `less` does).
This also significantly decreases our dependence on `termion`.
The pager was originally implemented by cloudhead in
40f4383bbc
and integrated into `rad diff` in
6dd52c94fb
This commit restores the behaviour introduced in
84a95848b0
(before there was a custom pager implementation).
