Exit & Restart Girder

[Cocophone]

Is it possible to have girder exit itself and restart itself?

I would like to restart girder using my remote when it seems to be acting up and needs a restart.

Thanks for any help.

You definitely should not need to do this...

What kind of problems are you having?

[Cocophone]

I using girder to get lyrics out of J River Music Center.

Some times it stops working and girder says it has a parsing error in the message part of the girder window.

If I restart Girder it starts working again.

Are you using luacom to talk with JRMC?

If so, there is a a problem with the luacom library reloading after a script engine reset. We are working on that.

[Cocophone]

I'm far from an expert, but that is what I'm doing.

I'm using Netremote to have girder pull the lyrics out of J River Media Center and then put them in a embedded web page on my pda

So sometimes it stops working. If I restart girder then it will usually start working again.

That's why I wanted to find out if I could have girder exit and restart itself. Maybe call a batch file that could do that.

Thanks

Why don't you post the exact error message from the script - Are you using Marcel's stuff?

[Cocophone]

I'm using Marcel's stuff.

All I see is the error message "Parse Error" on the bottom of the Girder Window border.

How do I get the error message that you need to figure out what is causing the problem?

Thanks

Open up the Girder Script window - ie. where the lua statements are. There is an output window which will catch the error. Just leave it open while Girder is running.

Ok...I got the error messages.

I had girder & J River Media Center running. I then exited J River Media Center and restarted Media Center. I then got the girder errors:

Error #1

error: attempt to call field `GetCurPlaylist' (a nil value)
stack traceback:
1: function `MCGetLyrics' [(none)]
2: main of (none)

Error #2

error: attempt to call field `GetCurPlaylist' (a nil value)
stack traceback:
1: function `MCGetBios' [(none)]
2: main of (none)


If I then exit Girder and restart Girder it will start working again.

Thanks

that is normal if you use my code (Which is not really my code, it was taken from Mike c's example on this board).....

Girder opens a connection with JRMC only the first time it gets some information. then it re-uses the connection handle every other time...

if you stop/start JRMC, then the connection handle becomes invalid, but the girder code doesn't know this....

you can change the lua code to disconnect/reconnect every time that you request something from JRMC or in case of an error..
It doesn't do that now...

I always have girder and JRMC running at the same time. so it is not a problem for me...

also as a side note, there are two ways of talking to JRMC -> direct (v10 only) or via MCIO.
If you have a direct connection active and you stop JRMC, it crashes after a long time. It doesn't do this if you have the connection open via MCIO (the above problem still occurs of course).

Marcel,

I have been playing with the direct connection in MC9 v.139 and the latest V10. Its seems to work much better. In my next release of LCD Master, I am planning on dropping MCIO.

What happens with the direct connect, is the user can close/open MC and the object remains valid.

Mike.

Hi Mike,

these are my experiences :

MCIO

start girder,MC,NR
request artist bio ok
stop MC
start MC
request artist bio fails

DIRECT

start girder,MC,NR
request artist bio ok
stop MC -> MC doesn't exit, just hangs.
KILL TASK
start MC
request artist bio fails

this is my code (part of my external .lua file)
you should recognize a lot of the code :D

replace MCConnectComDirect with MCConnectComMCIO for an MCIO connection :



Public.LYRICSHTML =""
Public.LYRICSTITLE =""
Public.LYRICSAVL =0


Private.MCComInit = 0
Private.MCServer = nil -- COM Object for MCIOServer
Private.MCA = nil -- basic COM object for interfacing to Media Center COM


function Private.MCConnectComMCIO ()

local MCStart = 1 -- start up MC if not running
local MCDelay = 15 -- time to wait for MC to get started

if (%Private.MCComInit == 0) then

if (%Private.MCA == nil) then
%Private.MCServer = luacom_CreateObject ("MCIOServer.MediaCentreInsideOutServer.1")
if not %Private.MCServer then
print ("Unable to connect to Media Center Inside Out Server")
return nil
end
%Private.MCA = %Private.MCServer:GetMJAutomationObject (MCStart,MCDelay)
if (%Private.MCA == nil) then
print ("Unable to connect to MC COM")
return nil
end
print ("MC connected using MCIO Server")
end

collectgarbage ()
%Private.MCComInit = 1
end
return 0
end

function Private.MCConnectComDirect ()

if (%Private.MCComInit == 0) then

if (%Private.MCA == nil) then
%Private.MCA = luacom_CreateObject ("MediaJukebox Application")
if (%Private.MCA == nil) then
print ("Unable to connect to MC COM")
return nil
end
print ("MC connected")
end

collectgarbage ()
%Private.MCComInit = 1
end
return 0
end


function Public.MCGetLyrics ()
%Public.LYRICSAVL = 0
%Public.LYRICSHTML = ""

%Private.MCConnectComDirect()

if (%Private.MCA ~= nil) then

local mjCurPlaylist = %Private.MCA:GetCurPlaylist()

if mjCurPlaylist then
local lCurrentlyPlaying = mjCurPlaylist:Position()

if &#40;&#40;lCurrentlyPlaying >= 0&#41; and &#40;lCurrentlyPlaying < mjCurPlaylist&#58;GetNumberFiles&#40;&#41;&#41;&#41; then

-- Get the file
mjTrack = mjCurPlaylist&#58;GetFile&#40;lCurrentlyPlaying&#41;

%Public.LYRICSTITLE = mjTrack&#58;Name&#40;&#41;

--CurrentFile = mjTrack&#58;Filename&#40;&#41;
%Public.LYRICSHTML =mjTrack&#58;Lyrics&#40;&#41;

%Public.LYRICSHTML = gsub&#40;%Public.LYRICSHTML, "\r", "
"&#41; -- \r

if &#40;strlen &#40;%Public.LYRICSHTML&#41; > 100&#41; then
%Public.LYRICSAVL = 1
end

end
lCurrentlyPlaying = nil

mjCurPlaylist = nil
end

collectgarbage &#40;&#41;
