From 44b421d4556486ba27a13c4f196219b2c37c190d Mon Sep 17 00:00:00 2001 From: Michael Davis Date: Sat, 3 Sep 2022 23:29:20 -0500 Subject: [PATCH] Look for the external formatter before invoking it (#3670) Currently it is not possible to save a file with a language that has an external formatter configuration unless the external formatter is installed, even if the language has a Language Server configuration capable of auto-format. This change checks that the external formatter exists before using it to create a formatting callback. --- helix-view/src/document.rs | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/helix-view/src/document.rs b/helix-view/src/document.rs index 3c406f8b52325..3f8dc4e6a7340 100644 --- a/helix-view/src/document.rs +++ b/helix-view/src/document.rs @@ -407,7 +407,11 @@ impl Document { // We can't use anyhow::Result here since the output of the future has to be // clonable to be used as shared future.
