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`.
