Extensions to Core.Core_String

collate s1 s2
sorts string in an order that's usually more suited for human consumption by treating ints specially, e.g. it will output: ["rfc1.txt";"rfc822.txt";"rfc2086.txt"]
.
It works by splitting the strings in numerical and non-numerical chunks and comparing chunks two by two from left to right (and starting on a non numerical chunk):
- Non_numerical chunks are compared using lexicographical ordering.
- Numerical chunks are compared based on the values of the represented ints and the number of trailing zeros.
It is a total order.
unescaped_exn s
is the inverse operation of escaped
: it takes a string where all the special characters are escaped following the lexical convention of OCaml and returns an unescaped copy. The strict
switch is on by default and makes the function treat illegal backslashes as errors. When strict
is false
every illegal backslash except escaped numeral greater than 255
is copied literally. The aforementioned numerals still raise errors. This mimics the behaviour of the ocaml lexer.
squeeze str
reduces all sequences of spaces, newlines, tabs, and carriage returns to single spaces.
val word_wrap :
?trailing_nl:bool ->
?soft_limit:int ->
?hard_limit:int ->
?nl:string ->
string ->
string
word_wrap ~soft_limit s
Wraps the string so that it fits the length soft_limit
. It doesn't break words unless we go over hard_limit
.
if nl
is passed it is inserted instead of the normal newline character.
Gives the Levenshtein distance between 2 strings, which is the number of insertions, deletions, and substitutions necessary to turn either string into the other. With the transpose
argument, it also considers transpositions (Damerau-Levenshtein distance).
