From 83b6042b97d13fca751e3d5d0c32f04e3ad04c9a Mon Sep 17 00:00:00 2001 From: Skyler Hawthorne Date: Sun, 24 Apr 2022 15:33:43 -0400 Subject: [PATCH] fix(write): do not set new path on document until write succeeds If a document is written with a new path, currently, in the event that the write fails, the document still gets its path changed. This fixes it so that the path is not updated unless the write succeeds. --- helix-term/src/application.rs | 26 +++++++++----- helix-term/src/commands/typed.rs | 9 ++--- helix-term/tests/test/write.rs | 61 ++++++++++++++++++++++++++++++-- helix-view/src/document.rs | 56 ++++++++++++++++++++--------- 4 files changed, 118 insertions(+), 34 deletions(-) diff --git a/helix-term/src/application.rs b/helix-term/src/application.rs index 2c1047da5..0640de3c4 100644 --- a/helix-term/src/application.rs +++ b/helix-term/src/application.rs @@ -3,6 +3,7 @@ use helix_core::{ config::{default_syntax_loader, user_syntax_loader}, diagnostic::{DiagnosticTag, NumberOrString}, + path::get_relative_path, pos_at_coords, syntax, Selection, };
