So I am aware that Unicode is not simple... I have been working
on a boxes like project http://boxes.thomasjensen.com/
it basically puts a pretty border around stdin characters. like
so:
________________________
/\ \
\_|Different all twisty a|
|of in maze are you, |
|passages little. |
| ___________________|_
\_/_____________________/
but I find that I need to know a bit more than the length of the
string because of encoding differences
I had a thought at one point to do this:
MyString.splitlines.map!(a => a.toUTF32.length).reduce!max();
Should get me the longest line.
but this has a problem too because control characters might not
take up space (backspace?).
https://en.wikipedia.org/wiki/Unicode_control_characters
leaving an unwanted nasty space :( or take weird amount of space
\t. And perhaps the first isn't really something to worry about.
Or should i do something like:
MyString.splitLines
.map!(a => a
.map!(a => a
.isGraphical)
.map!(a => cast(int) a?1:0)
.array
.reduce!((a,b) => a+b))
.reduce!max
Mostly I am just curious of best practice in this situation.
Both of the above fail with the input:
"hello \n People \nP\u0008ofEARTH"
on my command prompt at least.
