refren: refactor/rename

Build Status

The refren command facilitates refactoring/renaming in cases when you want to rename a concept that appears in your code rather than a specific variable or class. So, if you decide that "JS example" should be renamed to "javascript dummy", refren will do it for you, aware of different code styles.

Simple example

$ cat src/lib.js

```js const JSEXAMPLESTATIC_CONST = 44

function jsExampleFunction(firstJsExampleArgument, secondJsExampleArgument) { }

module.exports = { jsExampleFunction } ```

$ cat src/lib.js | refren 'JS example' 'javascript dummy'

```js const JAVASCRIPTDUMMYSTATIC_CONST = null

function javascriptDummyFunction(firstJavascriptDummyArgument, secondJavascriptDummyArgument) { }

module.exports = { javascriptDummyFunction } ```

Using together with the find command

refren can be easily used together with the find command:

$ find src -name "*.js" | xargs refren "JS example" "javascript dummy"
