I am trying to learn Racket by creating a Todo manager based on the Todo.txt
format by Gina Trapani (http://todotxt.com/)
I also have an Android tablet that uses a todo.txt application. This
application uses "\n\r" at the end of each line. I'm on Windows 7, so I need
this newline to work as well, because if I open the file up in Notepad, it
messes up my lines and my todos (normally one per line) become one multi-line
todo.
The program reads the text file using file->lines and filters any blank lines.
The program writes the text file and I manually write the "\n\r" using write,
display, and print. That is to say, I've tried all three and ended up with
extra "\n" characters.
Here is a snippet from my do-task procedure:
(with-output-to-file (task-file-path) #:mode 'text #:exists 'truncate/replace
(lambda ()
(write (string-join (drop-right uptos 1) "\n\r"))
(write "\n\r")
(write (complete-task (last uptos) (rest taskstuff)))
(write "\n\r")
(write (string-join afters "\n\r")))))
When I open the file with SciTe, it shows the CR and LF characters at the end
of each line, plus a blank line with a CR character.
The complite-task procedure transforms a task and returns a trimmed string.
Where is this extra blank line coming from?
