nixos/patches/flare/0004-feat-messages-Multi-select-messages-and-delete-for-m.patch
Simon Gardling bcdfd8cdf5 flare: add patched flare-signal with five local feature patches 
- patches/flare/000{1..5}-*.patch: typing indicators, formatted
  messages, edited messages, multi-select with delete-for-me, and
  in-channel message search. Mirror the matching commits in
  ~/projects/forks/flare and apply cleanly on top of upstream 0.20.4
  (which is what nixpkgs ships).
- home/profiles/gui.nix: include a flare-signal override that appends
  the patches via overrideAttrs. None of them touch Cargo.lock so the
  cargoDeps hash stays valid; signal-desktop stays alongside it.

Raw Blame History

From 250b11530e8d29a42707dde8ff3dd516e0073863 Mon Sep 17 00:00:00 2001
From: Simon Gardling <titaniumtown@proton.me>
Date: Wed, 29 Apr 2026 19:53:22 -0400
Subject: [PATCH 4/6] feat(messages): Multi-select messages and delete for me
- Add a 'Select' action to the message context menu that puts the
channel into selection mode and pre-selects the message. While in
selection mode, every message item shows a check button and a
toolbar replaces nothing in particular but offers a 'Delete for me'
destructive action plus a cancel button.
- Track selection state with a transient `selected` property on
`Message` and a `selection-mode` property on `Channel`. A new
`selection-changed` signal lets the channel-messages view update
the selection summary without polling.
- Add `Channel::delete_messages_locally` plus the matching
`Manager::delete_messages_locally` and a new
`Timeline::remove_by_timestamp` helper. The action only purges the
local copy and never sends a remote deletion.
