Markmap mindmap

This library provides a way to preview your MarkMap mind map in a panel while you are editing your space.

With MarkMap Preview, you can:

  • Preview your slides without leaving the context of your space
  • See how your slides look in real-time as you modify your markdown
  • Use the MarkMap Preview panel to navigate through your slides and see them in action

Configuration

To easily manage JS code source, we use a dynamic introspection mechanism based on md page path. If you don’t install program to default path Library/Malys/xxx,we have to set:

config.set("markmap.source ","xxxx")
-- ex: config.set("markmap.source ","Library/Malys/MarkmapMindmap")
-- where xxx is the path of MarkmapMindmap md page

Warning

Caution Depends on Utilities.md. It will be installed automatically.

Code

local source=config.get("markmap.source") or "Library/Malys/MarkmapMindmap"
local panelSize=config.get("markmap.panelSize") or 4

if library~=nil and (mls == nil or (mls ~=nil and mls.debug == nil)) then 
  library.install("https://github.com/malys/silverbullet-libraries/blob/main/src/Utilities.md")
  editor.flashNotification("'Utilities' has been installed", "Info")
end

local function isVisible()
  local current_panel_id = config.get("markmap.panelPosition") or "rhs"
  local iframe = js.window.document.querySelector(".sb-panel."..current_panel_id..".is-expanded iframe")  
  if iframe and iframe.contentDocument then  
    local el = iframe.contentDocument.getElementById("mindmap")  
    if el then  
      return true
    end
    return false
  end
end

local function show()
  local page_content = editor.getText()
  local contentBase64=encoding.base64Encode(page_content)
  local content1= mls.getCodeBlock(source,"innerHTML","@CONTENT@", contentBase64)
  local js = mls.getCodeBlock(source,"jsInject","@CONTENT@",content1)      
  local panel_html= mls.getCodeBlock(source,"template")
  local current_panel_id = config.get("markmap.panelPosition") or "rhs"
  editor.showPanel(current_panel_id,panelSize,  panel_html, js)
end

local function hide()
  local current_panel_id = config.get("markmap.panelPosition") or "rhs"
  editor.hidePanel(current_panel_id) 
end

local update = function(mode)  
  if ((not isVisible() and mode) or (not mode and isVisible())) then
    show()
  else
    hide()
  end
end  

-- Define the command
command.define({
    name = "Markmap: Toggle preview",
    description = "Toggle Marp slides render in a panel",
    run = function(e)
      update(true)
