+# isBinaryFile
+
+Detects if a file is binary in Node.js. Similar to [Perl's `-B` switch](http://stackoverflow.com/questions/899206/how-does-perl-know-a-file-is-binary), in that:
+- it reads the first few thousand bytes of a file
+- checks for a `null` byte; if it's found, it's binary
+- flags non-ASCII characters. After a certain number of "weird" characters, the file is flagged as binary
+
+Much of the logic is pretty much ported from [ag](https://github.com/ggreer/the_silver_searcher).
+
+Note: if the file doesn't exist, is a directory, or is empty, the function returns `false`.
+
+## Installation
+
+```
+npm install isbinaryfile
+```
+
+## Usage
+
+### isBinaryFile(filepath, callback)
+
+* `filepath`, a `string` indicating the path to the file.
+* `callback`, a `function` for the callback. It has two arguments:
+  - `err`, the typical Node.js error argument
+  - `result`, a `boolean` of `true` or `false`, depending on if the file is binary
+
+
+### isBinaryFile(bytes, size, callback)
+
+* `bytes`, a `Buffer` of the file's contents.
+* `size`, an optional `number` indicating the file size.
+* `callback`, a `function` for the callback. It has two arguments:
+  - `err`, the typical Node.js error argument
+  - `result`, a `boolean` of `true` or `false`, depending on if the file is binary
+
+
+### isBinaryFile.sync(filepath)
+
+* `filepath`, a `string` indicating the path to the file.
+
+
+### isBinaryFile.sync(bytes, size)
+
+* `bytes`, a `Buffer` of the file's contents.
+* `size`, an `number` indicating the file size.
+
+
+Returns a `boolean` of `true` or `false`, depending on if the file is binary.
+
+### Examples
+
+```javascript
+var isBinaryFile = require("isbinaryfile");
+
+fs.readFile("some_file", function(err, data) {
+  fs.lstat("some_file", function(err, stat) {
+    isBinaryFile(data, stat.size, function (err, result) {
+      if (!err) {
+        if (result) {
+          console.log("It is!")
+        }
+        else {
+          console.log("No.")
+        }
+      }
+    });
+  });
+});
+
+isBinaryFile.sync("some_file"); // true or false
+var bytes = fs.readFileSync(("some_file"));
+var size = fs.lstatSync(("some_file").size;
+isBinaryFile.sync(bytes, size); // true or false
+```
+
+## Testing
+
+Run `npm install` to install `mocha`, then run `npm test`.
