Macro](https://img.shields.io/badge/babel--macro-%F0%9F%8E%A3-f5da55.svg?style=flat-square)](https://github.com/kentcdodds/babel-plugin-macros)

Count lines or words in files at build time

## Installation

`count.macro` is a [Babel

macro](https://github.com/kentcdodds/babel-plugin-macros). This will work out of

the box with CRA, Gatsby, and Next.

```shell

npm install --save-dev count.macro

```

## Usage

Line and word information is based on the **source** file, not the output file.

For example, this file

```js

import { lines, linesIn, words, wordsIn } from "count.macro";

console.log(`This file has ${lines} lines`);

console.log(`lines.txt has ${linesIn("./lines.txt")}`);

console.log(`This file has ${words} words`);

console.log(`words.txt has ${wordsIn("./words.txt")}`);

```

will be transpiled to

```js

console.log(`This file has ${7} lines`);

console.log(`lines.txt has ${100}`);

console.log(`This file has ${25} words`);

console.log(`words.txt has ${1000}`);

```

### Named Exports

- `lines` is a number that will be transpiled to number of lines in current file

- `linesIn` is a function that takes a filename as an argument. The call will be replaced with the number of lines in the file (relative to the current file).

- `words` is a number that will be transpiled to number of words in current file.

- `wordsIn` is a function that takes a filename as an argument. The call will be replaced with the number of words in the file (relative to the current file).
