Hello
Consider the content of a file
````
First line \n
Second line ....
....
data data data data ... last char
````
My goal is to find out whether the last character is a new line
or not. Please not, it will be sufficient if this works on Linux.
More specifically I want to insert a new line at the end of the
file. File.writeline inserts a line at the end of the _newly
added line_.
Thus if I had
````
First line \n
Second line ....
....
data data data data ... non-NL-char
````
and wanted to insert : `newline-word-word-word ... non-NLchar`
Via `file.writeln`, it would end up as
````
First line \n
Second line ....
....
data data data data ... non-NL-char{no newline or whitespace
here}Newline-word-word-word ... non-NLchar{newline}
````
This is not unexpected. But, I want to make sure, that my
appending automatically adds a new line. However, it should not
add empty lines.
One brute force method is to copy every line of the file to a
temp file or in the RAM and then write back in the original file.
I would like to avoid that if possible.
Thanks.
