From 5a049df74ef7fca48380736e42e712803ddfa7ca Mon Sep 17 00:00:00 2001 From: Igor Somov Date: Mon, 15 Sep 2025 20:42:01 -0300 Subject: [PATCH 1/5] feat: implement MSC4352 customizable HTTPS permalink base URLs - Add discovery of custom permalink base from .well-known/matrix/client - Implement :permalink command for generating room/event permalinks - Add send-time conversion of HTTPS permalinks to matrix: URIs - Support both stable (m.permalink_base_url) and unstable keys - Feature-gated behind IAMB_MSC4352=1 environment variable - Include comprehensive tests and documentation Signed-off-by: Igor Somov --- Cargo.lock | 262 +++++++++++++++++++++++++----- Cargo.toml | 2 + MSC4352.md | 112 +++++++++++++ src/base.rs | 7 + src/commands.rs | 55 +++++++ src/main.rs | 65 ++++++++ src/message/compose.rs | 45 +++++- src/permalink.rs | 352 +++++++++++++++++++++++++++++++++++++++++ 8 files changed, 861 insertions(+), 39 deletions(-) create mode 100644 MSC4352.md create mode 100644 src/permalink.rs diff --git a/Cargo.lock b/Cargo.lock index 895ee653..a37235cb 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -482,10 +482,10 @@ dependencies = [ "bytes", "form_urlencoded", "futures-util", -
