Reading a specific line from a text file and changing the content of that line

[tass_co]

Hello everyone.

I have a TV show reminder skin.
I am reading data from txt file with webparser plugin.

I want to automatically change series dates, episode numbers, using lua script.

Text Line content pattern

Code: Select all

@@The Mandalorian@@S03E03@@15.03.23@@https://www.imdb.com/title/tt8111088/episodes?season=3@@https://proxyrarbg.org/torrents.php?search=tt8111088@@https://turkcealtyazi.org/mov/8111088/

ps: MeasureNames=> MeaName1 - MeaEp1 - MeaDate1 - MeaImdb1 - MeaSearch1 - MeaSub1

The places I want to change are the dates and episode numbers.

S03E04 and 22.03.23
(Episode number will increase by 1 and day will increase by 7 (not to exceed 30 and 31))

I want to do this separately for the first 3 rows but without success.

Since I don't know how to use Lua script, I could only add a new line to the text file. Without being able to change the date and episode numbers, of course.

Code: Select all

function Initialize()

end

function Edit1()
	MeaGetName = SKIN:GetMeasure('MeaName1')
	MeaGetEpisode = SKIN:GetMeasure('MeaEp1')
	MeaGetDate = SKIN:GetMeasure('MeaDate1')
	MeaGetIMDB = SKIN:GetMeasure('MeaImdb1')
	MeaGetSearch = SKIN:GetMeasure('MeaSearch1')
	MeaGetSubtitle = SKIN:GetMeasure('MeaSub1')
	
	MeaGetName1 = MeaGetName:GetStringValue()
	MeaGetEpisode1 = MeaGetEpisode:GetStringValue()
	MeaGetDate1 = MeaGetDate:GetStringValue()
	MeaGetIMDB1 = MeaGetIMDB:GetStringValue()
	MeaGetSearch1 = MeaGetSearch:GetStringValue()
	MeaGetSubtitle1 = MeaGetSubtitle:GetStringValue()
	
	local FileName = SKIN:GetVariable('Note')
	FilePath = SKIN:MakePathAbsolute(FileName)
	local file = io.open(FilePath, 'a')
	file:write('@@1',MeaGetName1, '@@',MeaGetEpisode1, '@@',MeaGetDate1,'@@',MeaGetIMDB1, '@@',MeaGetSearch1, '@@',MeaGetSubtitle1)
	file:close()
end

function Edit2()
	MeaGetName = SKIN:GetMeasure('MeaName2')
	MeaGetEpisode = SKIN:GetMeasure('MeaEp2')
	MeaGetDate = SKIN:GetMeasure('MeaDate2')
	MeaGetIMDB = SKIN:GetMeasure('MeaImdb2')
	MeaGetSearch = SKIN:GetMeasure('MeaSearch2')
	MeaGetSubtitle = SKIN:GetMeasure('MeaSub2')
	
	MeaGetName1 = MeaGetName:GetStringValue()
	MeaGetEpisode1 = MeaGetEpisode:GetStringValue()
	MeaGetDate1 = MeaGetDate:GetStringValue()
	MeaGetIMDB1 = MeaGetIMDB:GetStringValue()
	MeaGetSearch1 = MeaGetSearch:GetStringValue()
	MeaGetSubtitle1 = MeaGetSubtitle:GetStringValue()
	
	local FileName = SKIN:GetVariable('Note')
	FilePath = SKIN:MakePathAbsolute(FileName)
	local file = io.open(FilePath, 'a')
	file:write('@@2',MeaGetName1, '@@',MeaGetEpisode1, '@@',MeaGetDate1,'@@',MeaGetIMDB1, '@@',MeaGetSearch1, '@@',MeaGetSubtitle1)
	file:close()
end

function Edit3()
	MeaGetName = SKIN:GetMeasure('MeaName3')
	MeaGetEpisode = SKIN:GetMeasure('MeaEp3')
	MeaGetDate = SKIN:GetMeasure('MeaDate3')
	MeaGetIMDB = SKIN:GetMeasure('MeaImdb3')
	MeaGetSearch = SKIN:GetMeasure('MeaSearch3')
	MeaGetSubtitle = SKIN:GetMeasure('MeaSub3')
	
	MeaGetName1 = MeaGetName:GetStringValue()
	MeaGetEpisode1 = MeaGetEpisode:GetStringValue()
	MeaGetDate1 = MeaGetDate:GetStringValue()
	MeaGetIMDB1 = MeaGetIMDB:GetStringValue()
	MeaGetSearch1 = MeaGetSearch:GetStringValue()
	MeaGetSubtitle1 = MeaGetSubtitle:GetStringValue()
	
	local FileName = SKIN:GetVariable('Note')
	FilePath = SKIN:MakePathAbsolute(FileName)
	local file = io.open(FilePath, 'a')
	file:write('@@3',MeaGetName1, '@@',MeaGetEpisode1, '@@',MeaGetDate1,'@@',MeaGetIMDB1, '@@',MeaGetSearch1, '@@',MeaGetSubtitle1)
	file:close()
end

I would appreciate if you could help me improve the code

I am learning Lua script too.

S03E04 and 22.03.23
(Episode number will increase by 1 and day will increase by 7 (not to exceed 30 and 31))

Some code for the day part. Hope it helps.
