README
NaturalSort
NOTE v0.2 used an explicit second argument (case_sensitive).
This has been removed and replaced with an options keyword list,
this is a breaking change.
Sort a list of strings containing numbers in a natural manner.
Sort functions will not [generally] sort strings containing numbers the same way a human would.
Given a list:
["a10", "a05c", "a1", "a", "a2", "a1a", "a0", "a1b", "a20"]
Applying standard sort will produce:
["a", "a0", "a05c", "a1", "a10", "a1a", "a1b", "a2", "a20"]
But applying a natural sort will give:
["a", "a0", "a1", "a1a", "a1b", "a2", "a05c", "a10", "a20"]
Functions
Just the one:
NaturalSort.sort(list, options \\ [])
Sorts a list of strings (ascending).
This works by leveraging Elixir's
Enum.sort_by/3 function (which takes as the second argument
a mapping function). The mapping operation converts each string
into a list of strings and integers. Once in this form, applying
the sort function results in a correctly sorted list.
Options
There are currently two available options (passed as a
keyword list), :direction and case_sensitive.
:directionmay have a value of:ascor:desc, and defaults to:asc.:case_sensitivemay betrueorfalse, and defaults tofalse.
Examples
iex> NaturalSort.sort(["x2-y7", "x8-y8", "x2-y08", "x2-g8" ])
["x2-g8", "x2-y7", "x2-y08", "x8-y8" ]
iex> NaturalSort.sort(["a5", "a400", "a1"], direction: :desc)
["a400", "a5", "a1"]
iex> NaturalSort.sort(["foo03.z", "foo45.D", "foo06.a", "foo06.A", "foo"], case_sensitive: :true)
["foo", "foo03.z", "foo06.A", "foo06.a", "foo45.D"]
iex> NaturalSort.sort(["foo03.z", "foo45.D", "foo06.a", "foo06.A", "foo"], [case_sensitive: :true, direction: :desc])
["foo45.D", "foo06.a", "foo06.A", "foo03.z", "foo"]
Prior art:
VersionEye's naturalsorter gem was the inspiration, with that being based on Martin Pool's natural sorting algorithm, and making direct use of the Ruby implementation of the original C version.
Elixir's Version module does a similar thing.
Todo/Review
- REVIEW: Benchmark further.
- ENHANCEMENT: Add options: choice to use unicode, choice to strip whitespace from result.
- ENHANCEMENT: Stream rather than map - this was designed to aid me in organising vast amounts of files by name; mapping over large lists seems inefficient.
