After reading most of the tour.dlang.org website, I was
completely surprised & confused encountering 'KeepTerminator', a
'Flag' used by the File.byLine function. With no examples
denoting how to use it.
Most confusing was the way the documentation (website &
in-editor) used;
1. Yes.keepTerminator
2. KeepTerminator.yes
3. Flag!"keepTerminator".yes
& Don't get me started on the autocomplete trying to get me to
use KeepTerminator.Flag.yes (VSCode & code-d)
Now some documentation stated these flags are used to improve
readability, when compared to simple booleans, but all these
different notations seem super confusing, especially since I dont
understand why Flag requires a !"Name" part.
And I haven't read anything about it in the language tour, nor
have I found any discussion on the topic elsewhere.
I did find, for some reason, a second 'KeepTerminator'
documentation page . . . which is from std.string, which
understandably did not help clear things up.
Even further confused by the in-editor documentation, is this
function a template?:
"
byLine(Terminator = char, Char = char) (KeepTerminator
keepTerminator = No,keepTerminator, Terminator terminator = '\\n')
"
I'm sorry, I may be asking for too much, but I've got so many
questions and found few answers.
1. Did I miss some tutorial?
2. Why does flag require a name (!"Name")?
3. Is byLine a template, if so, how would one use it differently?
