include module type of Biocaml_base.LineA line is simply a string, possibly empty, that does not contain a newline character. As the name suggests, usually such strings are obtained by reading a file line by line.
val empty : tval parse_string : Base.string -> t Base.listparse_string s splits s on newline characters, returning the resuling list of lines. If the final line ended with a newline, the last string of the list is empty.
val rightmost : Base.string -> Base.string Base.option * trightmost s returns a pair whose right member is the longest suffix v of s that represents a line, while the possible remainder of s (minus the newline character) is represented in the left member. More formally, if v = s then the left member of the pair is None; otherwise it is Some u where s = u ^ "\n" ^
v.
val to_string : t -> Base.stringval of_string_unsafe : Base.string -> tReturn the given string without checking that it is a line. Useful for efficiency reasons if you're certain the given string is a line.
