Move the block to the next monday (context menu plugin for Roam) V1.2

move-to-next-monday.clj

;; Warning: this plugin adds a "⇨ Move to next Monday" item on both mobile and desktop Roam apps 
;; to the context plugin menu and to command pallete (Mac: Cmd-P / Windows: Ctrl-P, then search for "Move" or "monday" etc.). 
;; To activate Roam context menu on mobile, you need to install Victor Tabori's Long-tap script first: 
;; https://gist.github.com/thesved/48cab2307cf0598fcc5cd37643d36cb4
;; Installation:
;; 1) copy this block as children block `clojure` code block under parent containing {{[[roam/cljs]]}} anywhere 
;;    in [[roam/cljs]] page
;; 2) confirm "Yes, I know what I am doing"
;; 3) restart Roam
;; 4) desktop: right-click on any block context menu (on the bullet) / mobile: long-tap the bullet 
;; 5) choose Plugins/Move to Monday (attention: moves block including it's children; but do not worry: Cmd/Ctrl-Z works well)
;; PS: if the Monday's Daily Page does not exist, it is created first
;;

Updated to properly work on Sundays :) Sorry.

Updated today to reflect some RoamAlphaAPI changes and make it work again. :)

Bugfix + updated to better handle errors.
