We use `which::which` in many crates, so `which` was a separate
dependency across all of them. We can centralize `which` into the
stdx crate so it's easy for all crates to depend on it.
I also moved the rest of `helix-view/src/env.rs` into helix-stdx's
`env` module since it only contained a thin wrapper around `which`
and `std::env`.
This sets up a new Registers type that will allow us to expand support
for special registers. (See the child commits.)
We start simple with the regular (`Vec<String>`) registers and the
simplest special register, the black hole. In the child commits we
will expand these match arms with more special registers.
The upcoming special registers will need a few things that aren't
possible with the current Registers type in helix-core:
* Access to the `Editor`. This is only necessary when reading from
registers, so the `&Editor` parameter is only added to
`Registers::read`.
* Returning owned values. Registers in helix-core returns references
to the values backed by the `Vec<String>` but future special registers
will need to return owned values. We refactor the return value of the
read operations to give `Cow<str>`s and iterators over those.
* Returning a `Result` for write/push functions. This will be used by
the clipboard special registers.
* rework positioning/rendering, enables softwrap/virtual text
This commit is a large rework of the core text positioning and
rendering code in helix to remove the assumption that on-screen
columns/lines correspond to text columns/lines.
A generic `DocFormatter` is introduced that positions graphemes on
and is used both for rendering and for movements/scrolling.
Both virtual text support (inline, grapheme overlay and multi-line)
and a capable softwrap implementation is included.

* Add a test case for updating jumplists across windows
* Apply transactions to all views on history changes
This ensures that jumplist selections follow changes in documents, even
when there are multiple views (for example a split where both windows
edit the same document).
* Leave TODOs for cleaning up View::apply
* Use Iterator::reduce to compose history transactions

It is easy to forget to call `Document::apply` and/or `View::apply` in

closes over both calls.

This commit adds six new commands to interact with system clipboard:
- clipboard-yank
- clipboard-yank-join
- clipboard-paste-after
- clipboard-paste-before
- clipboard-paste-replace
- show-clipboard-provider
System clipboard provider is detected by checking a few environment
variables and executables. Currently only built-in detection is
supported.
`clipboard-yank` will only yank the "main" selection, which is currently the first
one. This will need to be revisited later.
Closes https://github.com/helix-editor/helix/issues/76
This is necessary to workaround ownership issues across function calls.
The issue notably arised when implementing the registers into `Editor`
and I was getting annoyed again when implementing copy/pasting into
system clipboard.
The problem is addressed by using macro calls instead of function calls.
There is no notable side effect.
User can select register to yank into with the " command.
A new state is added to `Editor` and `commands::Context` structs.
This state is managed by leveraging a new struct `RegisterSelection`.
