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. --- helix-term/src/commands.rs | 256 +++++++++++++++++++--------------------- helix-term/src/lib.rs | 3 + helix-term/src/ui/completion.rs | 6 +- helix-term/src/ui/editor.rs | 4 +- helix-term/src/ui/mod.rs | 10 +- helix-view/src/editor.rs | 29 +---- helix-view/src/lib.rs | 3 + helix-view/src/macros.rs | 29 +++++ 8 files changed, 172 insertions(+), 168 deletions(-) create mode 100644 helix-view/src/macros.rs (limited to 'helix-view') diff --git a/helix-term/src/commands.rs b/helix-term/src/commands.rs index 3ec06aaa..dc4805a5 100644 --- a/helix-term/src/commands.rs +++ b/helix-term/src/commands.rs @@ -52,27 +52,6 @@ pub struct Context<'a> { } impl<'a> Context<'a> { - #[inline] - pub fn view(&mut self) -> &mut View { - self.editor.view_mut() - } - - #[inline] - pub fn doc(&mut self) -> &mut Document { - let id = self.editor.view().doc;
