Main_OnCommandEx()

void Main_OnCommandEx(int command, int flag, void* proj)

You can call any REAPER action from ReaScript by using this API function.

e.g. RPR_Main_OnCommand(actionnumber, 0)

Find the action number for a given action by opening the Actions list, scroll the window right to show the action numbers. For example, from ReaScript you can call the REAPER action "Item: Split item under mouse cursor", like this:

RPR_Main_OnCommand(40746, 0)

This and the RPR_MIDIEditor functions are the APIs you need to start with if you're going to use ReaScript as an advanced macro language.

Parameters

int command,
int flag,
void* proj

Returns

void

Examples

C++

void DoInsRndFileEx(bool RndLen,bool RndOffset,bool UseTimeSel)
{
	if (g_filenames->GetSize()>0)
	{
		int filenameindex=rand() % g_filenames->GetSize();
 
		t_vect_of_Reaper_tracks TheTracks;
		XenGetProjectTracks(TheTracks,true);
		if (TheTracks.size()>0)
		{
		PCM_source *NewPCM=PCM_Source_CreateFromFile(g_filenames->Get(filenameindex));
		MediaItem *NewItem=AddMediaItemToTrack(TheTracks[0]);
		MediaItem_Take *NewTake=AddTakeToMediaItem(NewItem);
		double TimeSelStart=0.0;
		double TimeSelEnd=NewPCM->GetLength();
		GetSet_LoopTimeRange(false,false,&TimeSelStart,&TimeSelEnd,false);
		double ItemPos=TimeSelStart;
		double ItemLen=NewPCM->GetLength();
		double MediaOffset=0.0;
		if (RndOffset) 
		{
			MediaOffset=(NewPCM->GetLength()/RAND_MAX)*rand();
			ItemLen-=MediaOffset;
		}
		if (RndLen) ItemLen=((NewPCM->GetLength()-MediaOffset)/RAND_MAX)*rand();
		if (UseTimeSel) ItemLen=TimeSelEnd-TimeSelStart;
		if (!UseTimeSel) ItemPos=GetCursorPosition();
		GetSetMediaItemTakeInfo(NewTake,"P_SOURCE",NewPCM);
		GetSetMediaItemTakeInfo(NewTake,"D_STARTOFFS",&MediaOffset);
 
		GetSetMediaItemInfo(NewItem,"D_POSITION",&ItemPos);
		GetSetMediaItemInfo(NewItem,"D_LENGTH",&ItemLen);
		Main_OnCommand(40047,0); // build any missing peaks		SetEditCurPos(ItemPos+ItemLen,false,false);
		Undo_OnStateChangeEx("Insert random file (Extended)",4,-1);
 
		UpdateTimeline();
		}
	}
