## Change log |
|
|
|
### From 2.17 to 2.18 |
|
|
|
- New function `-iota` for generating arithmetic sequences |
|
(@holomorph, #215). |
|
|
|
- Calling `-list` with more than one argument is now deprecated. |
|
|
|
- `-lambda` now accepts an empty argument list. |
|
|
|
- New anaphoric macros `--reductions-from`, `--reductions`, |
|
`--reductions-r-from`, and `--reductions-r` corresponding to the |
|
analogous non-anaphoric functions. |
|
|
|
- `-doto` threading now works as with `->`. |
|
|
|
- New buffer-local minor mode `dash-fontify-mode` and globalized |
|
counterpart `global-dash-fontify-mode` for fontifying special Dash |
|
variables such as `it`, `it-index`, `acc`, etc. The minor mode also |
|
fontifies calls to Dash macros in older Emacs versions which did not |
|
dynamically detect macro calls. |
|
|
|
This obsoletes the user option `dash-enable-fontlock` and the |
|
function `dash-enable-font-lock`, which is now an alias of |
|
`global-dash-fontify-mode`. |
|
|
|
- New command `dash-register-info-lookup` for integration with `C-h S` |
|
(`info-lookup-symbol`). This command allows Dash symbols to be |
|
looked up in the Dash manual just like Elisp symbols are looked up |
|
in the Elisp manual. The command can be called directly when |
|
needed, or automatically from your `user-init-file`. For example: |
|
|
|
```el |
|
(with-eval-after-load 'info-look |
|
(dash-register-info-lookup)) |
|
``` |
|
|
|
- Dash is now listed under the standard [Customization |
|
groups](https://gnu.org/software/emacs/manual/html_node/emacs/Customization-Groups.html) |
|
and [Finder |
|
keywords](https://gnu.org/software/emacs/manual/html_node/emacs/Package-Keywords.html) |
|
`extensions` and `lisp`. |
|
|
|
- The Dash manual is now licensed under the GNU Free Documentation |
|
License version 1.3. |
|
|
|
- Various other bug fix, performance, byte-compilation, and |
|
documentation improvements. |
|
|
|
### From 2.16 to 2.17 |
|
|
|
- Sped up `-uniq` by using hash-tables when possible (@cireu, #305). |
|
- Fixed `-inits` to be non-destructive (@SwiftLawnGnome, #313). |
|
- Fixed indent rules for `-some->` and family (@wbolster, #321). |
|
- Added `-zip-lists` which always returns a list of proper lists, even for two |
|
input lists (see issue #135). |
|
|
|
### From 2.15 to 2.16 |
|
|
|
- Added `--doto`, anaphoric version of `-doto` (#282). |
|
- Aliased `-cons-pair-p` to `-cons-pair?` (#288). |
|
- Generalized `-rotate` for `|N|` greater than the length of the list (@leungbk, |
|
#290). |
|
- Added a mechanism to extend destructuring with custom matchers (@yyoncho, |
|
#277). |
|
|
|
### From 2.14 to 2.15 |
|
|
|
This release brings new destructuring features, some new control flow |
|
functions and performance optimizations. |
|
|
|
- Added `-setq` with destructuring binding support similar to the `-let` family |
|
(#116). |
|
- Added smarter key destructuring in `-let` and friends where variables are |
|
auto-derived from keys (#111). |
|
- Allowed `-let` bindings without a source value form (#256). |
|
- Added `-each-r` and `-each-r-while` (@doublep, #159). |
|
- Added `-common-suffix` (@basil-conto, #263). |
|
- Improved performance of folds (`-reduce` and friends) (@basil-conto, #264). |
|
|
|
### From 2.13 to 2.14 |
|
|
|
This release retired Emacs 23 support. |
|
|
|
- Added Edebug support for threading macros (@Wilfred). |
|
- Added `-unzip`. |
|
- Added support for `-first-item` and `-last-item` as [place |
|
forms](https://gnu.org/software/emacs/manual/html_node/elisp/Generalized-Variables.html). |
|
- Added `-powerset` and `-permutations` (@holomorph). |
|
- Added `-as->` for threading a named variable (@zck). |
|
- Added `-partition-after-pred`, `-partition-before-pred`, |
|
`-partition-after-item`, and `-partition-before-item` (@zck). |
|
- Fixed a bug in `-any-p` and friends testing for `null` on lists containing |
|
`nil` (#239). |
|
- Fixed infinite loop bug in `-zip` and `-interleave` when called with empty |
|
input. |
|
- Added `-second-item` through `-fifth-item` as alternatives to `nth` |
|
(@Wilfred). |
|
- Added `-tails` and `-inits`. |
|
- Added `-running-sum` and `-running-product`. |
|
- Added the `-reductions[-r][-from]` family of functions (like `-reduce` but |
|
collecting intermediate results). |
|
- Added `-common-prefix` (@basil-conto). |
|
|
|

|
|
|
- `-let` now supports `&alist` destructuring. |
|

|
26](https://srfi.schemers.org/srfi-26/srfi-26.html) (#185). |
