A modern list api for Emacs. No 'cl required.
It's available on marmalade and Melpa:
M-x package-install dash
Or you can just dump dash.el in your load path somewhere.
[[ function-list ]]
There are also anaphoric versions of these functions where that makes sense, prefixed with two dashs instead of one.
While -map takes a function to map over the list, you can also use
the anaphoric form with double dashes - which will then be executed
with it exposed as the list item. Here's an example:
(-map (lambda (n) (* n n)) '(1 2 3 4)) ;; normal version
(--map (* it it) '(1 2 3 4)) ;; anaphoric versionof course the original can also be written like
(defun square (n) (* n n))
(-map 'square '(1 2 3 4))which demonstrates the usefulness of both versions.
[[ function-docs ]]
Run the tests with
./run-tests.sh
Create the docs with
./create-docs.sh
I highly recommend that you install these as a pre-commit hook, so that the tests are always running and the docs are always in sync:
cp pre-commit.sh .git/hooks/pre-commit
Oh, and don't edit README.md directly, it is auto-generated.
Change readme-template.md or examples-to-docs.el instead.
