1.
I want to get the current time of vlc on to clipboard. The following is an extension for this purpose.
I am new to LUA.
This extension is modified based on Time.

Many thanks to lubozle.
2.
Putting this simple extension here, I hope those who is not familiar with LUA can get something from it.
Also, if there is any bug with this extension, you are welcomed to point it out.
3.
I use

Code: Select all

strCmd = 'echo '..var..' |clip'
os.execute(strCmd)

to put variable into clipboard, is there a direct way to do this in LUA?

Code: Select all

-- Time2Clip.lua -- VLC extension --
--[[
INSTALLATION:
Put the file in the VLC subdir /lua/extensions, by default:
* Windows (all users): %ProgramFiles%\VideoLAN\VLC\lua\extensions\
Restart the VLC.
Then you simply use the extension by going to the "View" menu and selecting it.

	return {
		title = "Time2Clip";
		version = "1.0";
		author = "valuex";
		url = 'http://addons.videolan.org/content/show.php?content=149618';
		shortdesc = "Time2Clip";
		description = "<div style=\"background-color:lightgreen;\"><b>just a simple VLC extension </b></div>";
		capabilities = {"input-listener"}
	}
end
function activate()
	input_callback("add") 
	create_dialog()
end
function deactivate()
	input_callback("del")
end
function close()
	vlc.deactivate()
end
function input_changed()
	input_callback("toggle")
end

callback=false
function input_callback(action)  -- action=add/del/toggle
	if (action=="toggle" and callback==false) then action="add"
	elseif (action=="toggle" and callback==true) then action="del" end

	local input = vlc.object.input()
	if input and callback==false and action=="add" then
		callback=true
		vlc.var.add_callback(input, "intf-event", input_events_handler, "Hello world!")
	elseif input and callback==true and action=="del" then
		callback=false
		vlc.var.del_callback(input, "intf-event", input_events_handler, "Hello world!")
	end
end

function input_events_handler(var, old, new, data)

end

function create_dialog()
	w = vlc.dialog("Time2Clip")
	w1 = w:add_label("<b>CurrentTime:</b>",1,1,1,1)
	w2 = w:add_text_input("0",2,1,1,1)	
	w3 = w:add_button("jumpto", click_SEEK,1,2,1,1)
	w4 = w:add_button("Save_to_Clip", click_SAVE,2,2,1,1)
end

function click_SAVE()
	local input = vlc.object.input()
	if input then
		local curtime=vlc.var.get(input, "time")
		w2:set_text( curtime )
		save_to_clipboard(curtime)
	end
end

function click_SEEK()
	local time_togo = w2:get_text()
	local input = vlc.object.input()
	if input then
		vlc.var.set(input, "time", time_togo)	--jump to specified time
	end
end

function save_to_clipboard(var)
	strCmd = 'echo '..var..' |clip'
	os.execute(strCmd)
end

Thanks for the script bringing new ideas.
You should also tell users to download "clip.exe" from Internet as it is not available in all Windows versions. At least my Windows XP SP2 does not have one. Copy Command Line Output to Windows Clipboard Directly

You can remove some more redundancies from the script that you do not need there at all:
capabilities = {"input-listener"}
input_callback("add")
input_callback("del")
function input_changed()
function input_callback(action)
function input_events_handler(var, old, new, data)
Please edit your post and remove these functions from the code to make it simpler and more understandable.
Good work. Thanks.

Mederi, thanks for your wonderful reply.
I've modified this extension according to your suggestions.
Now it looks more concise.
Here is the results.

Code: Select all

-- Time2Clip.lua -- VLC extension --
--[[
INSTALLATION:
Put the file in the VLC subdir /lua/extensions, by default:
* Windows (all users): %ProgramFiles%\VideoLAN\VLC\lua\extensions\
* Windows (current user): %APPDATA%\VLC\lua\extensions\
(create directories if they don't exist)
Restart the VLC.
Then you simply use the extension by going to the "View" menu and selecting it.
Note:
	This extension has been tested for VLC 2.0.1 on Win7 sp1.
	Because the function  save_to_clipboard needs clip.exe, you've to make sure your windows system has it (just type "echo a |clip" in the cmd prompt window to check whether letter "a" has been put in the system clipboard). 
	If it doesn't exist, you can download it from here:
