The need for this came up during some space-lua shenanigans:

Command Lua: Toggle space-lua on Page

Turns all space-lua codeblocks on any page (current by default) on and off.

:warning: needs a System: Reload to be effective

Usage

On this page:  {[Lua: Toggle space-lua on Page]}

On another page: {[Lua: Toggle space-lua on Page|Toggle space-lua on warpcore]("engineering/warpcore")}

```space-lua
command.define{
  name = "Lua: Toggle space-lua on Page",
  requireMode = "rw",
  run = function(arg)
    local my_path = arg[1] or _CTX.currentPage.name
    editor.flashNotification("Lua: Toggle space-lua on Page "..my_path)

    local my_page = space.readPage(my_path) or ""    
    local count, action
   
    if string.find(my_page,"```space-lua-DISABLED\n") then
      my_page, count = string.gsub(my_page,"```space-lua-DISABLED%s*\n","```space-lua\n")
      action = "☑️ Enabled "
    else
        my_page, count = string.gsub(my_page,"```space-lua%s*\n","```space-lua-DISABLED\n")
      action = "❌ Disabled "
    end

    if count==0 then
      editor.flashNotification("❔ Nothing to do: Found no space-lua codeblocks on "..my_path)
    else
      editor.flashNotification(action..count.." space-lua codeblocks on "..my_path)
    end
    
    if my_path == _CTX.currentPage.name then
      editor.setText(my_page)
    else
      space.writePage(my_path,my_page)
    end
    codeWidget.refreshAll()
  end
}
