v2.4 (not yet tagged)

Switched to GitHub Actions for automated testing.

Features

  • Added ht-update-with!. This is like Racket's hash-update!.

Bug Fixes

  • ht-select-keys can now select keys whose values happen to be the symbol key-not-found.

  • Corrected the documentation for ht-reject!.

v2.3

Features

  • Added ht-empty-p as an alias of ht-empty?.

  • Many functions have been marked as side-effect-free, improving performance and byte-compiler warnings.

  • ht-get and ht-get* can now be used with setf, e.g.

(setf (ht-get my-table my-key) new-value)

Bug Fixes

  • ht<-plist now keeps the first item in the list, if there are duplicates. This makes it consistent with ht<-alist and plist-get.

  • ht-get* now handles an empty list of keys correctly, and will no longer stack overflow on large lists of keys.

  • ht-contains-p now even supports hash tables that contain the key ht--not-found.

v2.2

  • Added ht-select-keys
  • Added ht-get*

ht.el now uses defsubst for many of its functions, which may improve performance in byte-compiled code.

v2.1

  • ht<-alist and ht<-plist gained an optional argument test to specify the equality predicate.
  • Added ht-equal?.

v2.0 -- API Change

Functions names have been changed to be more explicit and consistent.

Note that ht.el includes aliases, so v2.0 is fully backwards compatible.

Mutation functions now always end with !, and ht-delete-if has been renamed for consistency with its non-mutating equivalent ht-reject.

  • ht-set -> ht-set!
  • ht-update -> ht-update!
  • ht-remove -> ht-remove!
  • ht-clear -> ht-clear!
  • ht-delete-if -> ht-reject!

Predicates now always end with ?.

  • ht-p -> ht?
  • ht-contains-p -> ht-contains?

Conversion functions now use <- and ->.

  • ht-to-alist -> ht->alist
  • ht-to-plist -> ht->plist
  • ht-from-alist -> ht<-alist
  • ht-from-plist -> ht<-plist

v1.6

  • Added ht-reject and ht-select
  • Added ht-delete-if
  • Added ht-find
  • Added ht-empty? and ht-size

Also added Travis configuration.

v1.5

  • ht-aeach now evaluates to nil as it should (use ht-amap if you want the resulting hash table).

v1.4

  • Added ht-merge.

v1.3

  • Removed runtime dependency on cl.

v1.2

  • Fixed various void-variable crashes due to ht-amap only being declared after its usage.

v1.1

  • Added ht-contains-p.

v1.0 -- API Change

  • ht-map now returns a list, as you'd expect a map function to do.
  • Added ht-each for when you're only interested in side-effects.
  • Added an anaphoric version of ht-each, ht-aeach.

v0.11

  • Added ht-map and an anaphoric version ht-amap.

v0.10

  • Added ht-p, an alias of hash-table-p, (mainly for completeness).

v0.9

  • Added ht-update.

v0.8

  • Added the ht macro to make hash table literals easy

v0.7

  • Added ht-to-alist and ht-to-plist

v0.6

  • Fixed a bug where ht-from-alist would overwrite the latest key-value association with older ones

v0.5

  • Added ht-from-plist

v0.4

  • Added ht-from-alist

v0.3

  • Added ht-copy

v0.2

  • Changed functions from hm-* to ht-* (Emacs doesn't use the term hash map)

v0.1

  • Initial release
