Add new lines to text file and read them

[Medien Forscher]

Hi
I can add new lines to text files with +"\n" but when I read the file with var txt = app.ReadFile the line breaks are apparently not read.

When I write it with img.DrawText(txt,0.1, 0.35, "Multiline");

The linebreaks are gone or ignored.
Thx
Olivier

Short thing: How can I write \n in a text file that will be read by multiline option?

\n is the right way to do it.

My guess is you're writing it fine.

Have you tried looking at it in a text editor.

Unless it's something that has been added very recently, img.DrawText does not have a MultiLine option.

GetTextSize was added so you can calculate for yourself where the line breaks and where to start drawing the next line.

Thx I managed now to get the \n in my text file (\\n). Now I see something weird. If I take the string text in following code the linebreak works. If I take the string from a textfile the line break doesn't work. Here's the code:

function OnStart() {
lay = app.CreateLayout( "Linear", "VCenter,FillXY" );

//text = "Hello\nWorld";
text = app.ReadFile( "/sdcard/testfile.txt" );
txt = app.CreateText( text, 0.8, 0.2, "Multiline" );
txt.SetTextSize( 12 );
txt.SetTextColor( "#ff6666ff" );
txt.SetBackColor( "#ffffffff" );
lay.AddChild( txt );
app.AddLayout( lay );
}

And here the textfile content:

09/09/2018,57,57,0,0,0,0,00:00:02\n09/09/2018,60,60,0,0,0,0,00:00:01\n

If you put this in a textfile does it break the line with above code?

[Steve Garman]

Don't double the soashes.

If it looks like
a\nb
in a text editor, it isn't a line break.

In a text editor, a line break should look like
a
b

But that's still not going to help you with your DrawText problem.

Did you read my last pist?

Thx very much, that solved the problem. I read it and therefore choose app.CreateText which supports multiline. So now I can show a simple trainig history. Great, thx!
