package core_extended

Release v0.17.0

• Added Bitarray.count, which returns the number of bits set to true in a given prefix of the array.

• New features in Delimited_kernel:

  • Add label functions to tag exceptions with additional information about the reader

  • Add list_of_headers function to retrieve the list of headers in the order they appear in the file, at the level of an individual file, as opposed to an individual row.

• Improvements to Find_files:

  • Expose exceptions to error handlers, so e.g. they can be logged.

  • Added detailed comments to each field in Find_files.Options.t explaining their purpose and equivalence to Unix find flags.

• Add Immediate, containing modules and interfaces for immediate versions of standard datatypes. "Immediate" is used here in the sense of Obj.is_int.

• Changes to Selector:

  • Selector.String_selector.of_regexp now accepts an optional opts parameter for regular expression options.

  • Added [@@deriving stable_witness] to Selector.Stable.V1.

Release v0.16.0

• Added `Fallback option to Read.On_invalid_row.

• Added Read.fold_lines.

• Added Write.Out_channel to support line-by-line printing to stdout.

Old pre-v0.15 changelogs (very likely stale and incomplete)

113.43.00

• Export the interval map module type.

• Ocaml interface to the Unix pseudo-terminal functions

• Extended_list.fold_left_term is no longer needed - we now have List.fold_until.

113.33.00

• Update to follow core[_kernel] evolution.

113.24.00

N.B. Some interface changes occured in Core which are repercuted in this package, they are not all list in this file though.

• Switched to PPX.

• Upgrade Interval_map.t with monad operations.

• Update the interval_map_intf.ml file to try to make the documentation clearer.

  This mostly constitutes splitting out the core operations into a separate module type earlier in the file, so that their documentation occurs before the various more specific module types in reading order.

  Various bits of documentation have been tweaked with examples or laws.

• Add underscores to color print names Improve and uniformize the behavior of colorprintf functions at the cost of changing the type slightly

• Fix core_extended stubs on openbsd

  Closes #7 Closes #2

• Move Core_extended.Std.Sys.home to Core.Std.Sys.home_directory.

• Add a module whose type 'a t acts as a container of ordered items of type 'a (morally, a 'a list) but which supports efficient append operations.

  Sometimes called a Rope, or Concatenable_list.

• Expose the constructors of Ascii_table.Align.t so that we can write

  Column.create ~align:Left ...

  instead of

  Column.create ~align:Align.left

• Fix sexp diffing on records The wrong comparaison was leading to huge diff as soon as one field was missing on one side

113.00.00

• Added to Interval_map a more complete set of operations.

• Removed Core_extended.Sexp.filter_record, which has been superseded by Core.Std.Sexp.of_sexp_allow_extra_fields.

• Added to Interval_map an Interval module, with the type of intervals used in an interval map.

• In Color_print, added sprintf functions, and changed formatting to compose properly.

112.35.00

• Removed the Stats_reporting module.

• Renamed Quickcheck module to Quickcheck_deprecated. It's replaced by Janecheck, which for now is a separate library in the core_extended package, but will soon be merged into core.

• Moved the Selector module to its own library. This is for internal reasons related for code review; it is included as a library within the core_extended package for now, but may move to another home in the future.

• Added Extended_unix.terminal_width : int Lazy.t.

• Added Interval_map module.

• Added to Sendmail.send additional optional arguments: ?message_id:string, ?in_reply_to:string.

112.24.00

• Added to Shell.set_defaults a ?preserve_euid:bool argument, which causes Shell to use bash -p.

• Removed Array.Access_control, now that there is Core.Std.Array.Permissioned.

• Removed Fast_int_div.

112.17.00

• Added functions to Low_level_debug to get a sexp or string representation of any type.

  This could be handy when debugging polymorphic code.

• Renamed String.is_substring to is_substring_deprecated. Use Core.String.is_substring instead.

• Fixed a bug in Bin_io_utils.save.

• Made Unix.Mac_address match Hashable.S.

112.06.00

• Sped up String.is_substring by replacing the OCaml implementation with a call to libc memmem.

  memmem runs in 20% of the time, incurs minimal GC pressure, is portable among UNIXen that we target, AND it's clearer than the ML version.

• Made Float_ref support bin_io and sexp.

• Removed gettid, which is now available in Core.Unix.

• Added Fast_int_div module, which speeds up integer division by a fixed divisor.

• Moved Sexp.of_sexp_allow_extra_fields to core_kernel.

112.01.00

• Added Float_ref module, which is like float ref but faster for sets due to bypassing the write barrier.

  Benchmark results on Sandy Bridge:

  | [float_ref.ml:] float ref set | 2_886.94ns | 8.00w | | | [float_ref.ml:] Float_ref.set | 355.76ns | 6.00w | | | [float_ref.ml:] float ref get | 415.52ns | 6.00w | | | [float_ref.ml:] Float_ref.get | 416.19ns | 6.00w | |

• Added Bin_io_utils.Wrapped.t, which defines an 'a t with bin_io that supports size-prefixed serialization and deserialization.

  Wrapped has two useful submodules, Opaque and Ignored, for efficient handling of size-prefixed bin-io values in cases where serialization can be bypassed. See the comments in the module for more details.

111.28.00

• Implemented Int.gcd using binary GCD in C, for improved performance.

• Added Bin_io_utils.Serialized, which stores a value in memory as its bin-io representation.

  Writing such a value just blits the value.

• Moved Text_block from Core_extended into Textutils.

• Added modules Hashtbl2 and Hashtbl2_pair.

111.25.00

• Moved Quickcheck from core.

• Added [Int.gcd].

111.17.00

• Added some functions to Splay_tree:

  • length

  • keys

  • data

  • to_alist

  • delete_{after,before}

  • map

  • map_range

  • split.

111.13.00

• Moved Patience_diff out of Core_extended into its own library.

111.11.00

• For Flang, added ordering to fields, and added abs, min, and max to the language.

• Removed Loggers module.

111.03.00

• Added Set_lang, a DSL for sets with constants, union, intersection, and difference.

• In Process, use epoll rather than select when possible,

  This prevents errors when selecting on file descriptors numbered greater than FD_SETSIZE (1024).

• Removed Syslog module. There is now Unix.Syslog in core instead; the APIs are not compatible, but they are similar.

109.58.00

• Cleaned up the Stats_reporting module

109.55.00

• Added Service_command.acquire_lock_exn, for acquiring a service's lock.

109.53.00

• Fixed Flang and Olang to round-trip via sexps, i.e. (t_of_sexp (sexp_of_t t)) = t.

109.52.00

• Removed Sexp.load_sexp_with_includes; one should use the new Sexplib.Macro functions.

• Added Blang-like languages Flang and Olang.

  • Flang -- terms over a field.

  • Olang -- predicates over an ordered set.

109.45.00

• Fixed Core_extended.Sys.groups to use Unix.Group.getbygid rather than Unix.Group.getbygid_exn.

  This handles when a group is deleted and its gid remains in the cache, which causes Unix.Group.getbygid_exn to fail because the gid no longer resolves to a group.

109.40.00

• Added Stats_reporting.Delta, for recording deltas of values.

109.36.00

• In Sexp module, added ability to expand and compress bash-like brace wildcards.

109.35.00

• Added stable versions of types contained in the Selector module.

109.34.00

• Improved Sexp.Diff.

  Labeled arguments, put them in the right order (old before new), and rework the code to follow the same convention, and produce the output where deletions precede insertions.

109.28.00

• In Shell functions, made the amount of captured stderr/stdout configurable.

109.27.00

• In module Sexp, changed and renamed load_includes_in_sexp.

  From:

  val load_includes_in_sexp : ?max_depth:int -> Sexp.t -> Sexp.t
  

  to:

  val load_sexp_with_includes: ?max_depth:int -> ?buf:string -> string -> Sexp.t
  

• Added function Sexp.Diff.to_string.

• Previously the only option was to print to Out_channel.
