Lua: How do you get Marker Time?

[tXShooter]

I had thought that I had seen this answered somewhere before, but if I had I can't recall where.

How do you get the Marker Time when you have markrgnidx?

[cfillion]

With EnumProjectMarkers.

[dsyrock]

markrgnidx=xx

local num=reaper.CountProjectMarkers(0)

local MarkerTime

for i=0, num-1 do

	local _1, _2, pos, _3, _4, index=reaper.EnumProjectMarkers(i)

	if index==markrgnidx then 

		MarkerTime=pos

		break

	end

end

reaper.ShowConsoleMsg("The Marker Time is: "..tostring(MarkerTime) .. "\n")

Just change the "xx" in first line to the number you want

You dont have to loop in markers for that there is a get marker by ID function API natvely.

Really? Which API can do that? I checked that API list again and still confusing

[amagalma]

There is DeleteProjectMarkerByIndex and SetProjectMarkerByIndex, but there is not a Get one, AFAIK

Hmmm you are right, maybe it was a custom function I made.


I would say that if you have to build your own Get project Marker by Index, first loop on all markers, store them in table with key as idx, and then just access the key, it will be far more efficient than having the markers loop called each time you need to access the function.


Note: reaper.GoToMarker( proj, marker_index, use_timeline_order ) take idx apparently.

[amagalma]

local mrk_cnt = reaper.CountProjectMarkers(0)
local markers, regions = {}, {}
for i=0, mrk_cnt-1 do
  local _, isrgn, pos, rgnend, name, index = reaper.EnumProjectMarkers( i )
  if isrgn then
    regions[index] = {Start = pos, End = rgnend, Name = name}
  else
    markers[index] = {Pos = pos, Name = name}
  end
end

-- EXAMPLES
-- Get time of marker with markrgnidx 2
time = markers[2].Pos
-- Get name of region with index 1
name = regions[1].Name

I think this will work...

function MarkerTime() -- Define 'num' if calling with a known markerindex number: MarkerTime(num)
	local num = reaper.CountProjectMarkers(0) -- delete if using MarkerTime(num)
	local MarkerTime
	local _1, _2, MarkerTime, _3, _4, index=reaper.EnumProjectMarkers(num-1)
	MarkerTime = reaper.format_timestr(MarkerTime, "")
	-- reaper.ShowConsoleMsg("The Marker Time is: "..tostring(MarkerTime) .. "\n")
	return MarkerTime
end

If I understand how things work... I'm not having to set the markerindex prior to calling because in my use I set the marker just prior to calling this, so by default it's the last marker in the index.

My next question about this is: While recording, if I wanted to include in the text of the Marker what its time is, would there be a way of grabbing the time just prior to reaper.AddProjectMarker(0,0, reaper.GetPlayPosition(),0,MarkerText,-1)?

local playpos = reaper.GetPlayPosition()
local Name = "Seconds" -- or whatever name you wish
reaper.AddProjectMarker( 0, false, playpos, 0, Name .. " " .. math.floor(playpos*100+0.5)/100, -1)

This gives the time in seconds and two decimal places. Do you want it in another format?

Thank you, amagalma.

I used your information to formulate:

function GetPlayPosition()
	local playpos = reaper.GetPlayPosition()
	playpos = reaper.format_timestr(playpos, "")
	return playpos
end

I had done something similar to this before but had forgotten it. It sucks getting old.
