View Source mix es6_maps.format (es6_maps v0.2.1)
Replaces all map keys with their shorthand form.
mix es6_maps.format 'lib/**/*.ex' 'test/**/*.exs'
The arguments are expanded with Path.wildcard(match_dot: true)
.
The task manipulates the AST, not raw strings, so it's precise and will only change your code by:
- changing map keys into the shorthand form;
- reordering map keys so the shorthand form comes first;
- formatting the results with
mix format
.
Going back to old-style maps
You can revert all of the ES6-style shorthand uses with the --revert
format flag:
mix es6_maps.format --revert lib/myapp/myapp.ex
Reordering map keys
When applicable, the formatting will reorder the keys to shorthand them, for example:
%{hello: "world", foo: foo, bar: bar} = var
will become:
%{foo, bar, hello: "world"} = var
Options
--revert
- Reverts the transformation.--locals-without-parens
- Specifies a list of locals that should not have parentheses. The format islocal_name/arity
, wherearity
can be an integer or*
. This option can be given multiple times, and/or multiple values can be separated by commas.
