MacrowEx
provides DSL for defining rules of text replacing.
It's inspired by https://github.com/syguer/macrow Ruby gem.
If available in Hex, the package can be installed
by adding macrow_ex
to your list of dependencies in mix.exs
:
def deps do
[
{:macrow_ex, "~> 0.1.1"}
]
end
Define your module and write use MacrowEx
.
MacrowEx provides rules/2
DSL to define replacement rules.
The second argument is function to replace and must return string.
defmodule MyMacrowEx do
use MacrowEx
rules "hoge", fn ->
"ほげ"
end
rules "len", fn array ->
length(array) |> Integer.to_string()
end
end
Then apply/1
apply/2
function generates in your module.
MyMacrowEx.apply("${hoge}")
"ほげ"
MyMacrowEx.apply("${hoge} length is ${len}", [1,2,3])
"ほげ length is 3"
You can customize default prefix ${
and suffix }
as follows.
defmodule MyMacrowEx do
use MacrowEx
macro_prefix "{{"
macro_suffix "}}"
rules "hoge", fn ->
"ほげ"
end
end
MyMacrowEx.apply("{{hoge}}")
"ほげ"
When you do not want to format DSL provided by MacrowEx, try to write in your .formatter.exs
as follows.

import_deps: [:macrow_ex]
