From 4eabe2d841f68855d971e209ad766bc6a3b78d2e Mon Sep 17 00:00:00 2001 From: Noam Lewis Date: Thu, 5 Feb 2026 22:42:05 +0200 Subject: [PATCH 01/26] feat: add --wait flag to open-file for $EDITOR use case When --wait (-w) is specified, the client blocks until all opened files are closed in the editor. This enables using fresh as $EDITOR for git commit, git rebase -i, crontab -e, etc. Protocol changes: - OpenFiles message now has a `wait` boolean field - Server sends BufferClosed messages when buffers are closed - Client waits for all BufferClosed messages before exiting Also refactors CLI parsing to use ParsedCommand struct instead of a large tuple for better readability. Usage: fresh --cmd session open-file --wait main COMMIT_EDITMSG Co-Authored-By: Claude Opus 4.5 --- .../fresh-editor/src/app/buffer_management.rs | 17 + crates/fresh-editor/src/main.rs | 333 ++++++++++-------- .../fresh-editor/src/model/control_event.rs | 8 +- .../fresh-editor/src/server/editor_server.rs | 81 ++++- crates/fresh-editor/src/server/protocol.rs | 9 +- 5 files changed, 296 insertions(+), 152 deletions(-) diff --git a/crates/fresh-editor/src/app/buffer_management.rs b/crates/fresh-editor/src/app/buffer_management.rs index fd31f2584..297280a45 100644 --- a/crates/fresh-editor/src/app/buffer_management.rs +++ b/crates/fresh-editor/src/app/buffer_management.rs @@ -1322,6 +1322,13 @@ impl Editor { /// Internal helper to close a buffer (shared by close_buffer and force_close_buffer) fn close_buffer_internal(&mut self, id: BufferId) -> anyhow::Result<()> { + // Get file path before closing (for FILE_CLOSED event) + let file_path = self + .buffer_metadata + .get(&id) + .and_then(|m| m.file_path()) + .map(|p| p.to_path_buf());

Features: - Shows "Reinstall" button next to "Uninstall" for packages with source - Prompts user for confirmation before reinstalling - Performs clean reinstall (uninstall + fresh install) - Useful for getting latest changes without git conflicts Implementation: - Added reinstallPackage() function - Modified getActionButtons() to show Reinstall button - Packages already track installation source from git remote URL - Handles button click in pkg_activate command The button label is "Reinstall" rather than "Upgrade" to clearly distinguish from "Update" (git pull) vs "Reinstall" (uninstall + install).
