+# rollup-pluginutils
+
+A set of functions commonly used by Rollup plugins.
+
+
+## Installation
+
+```bash
+npm install --save rollup-pluginutils
+```
+
+
+## Usage
+
+### addExtension
+
+```js
+import { addExtension } from 'rollup-pluginutils';
+
+export default function myPlugin ( options = {} ) {
+  return {
+    resolveId ( code, id ) {
+      // only adds an extension if there isn't one already
+      id = addExtension( id ); // `foo` -> `foo.js`, `foo.js -> foo.js`
+      id = addExtension( id, '.myext' ); // `foo` -> `foo.myext`, `foo.js -> `foo.js`
+    }
+  };
+}
+```
+
+
+### attachScopes
+
+This function attaches `Scope` objects to the relevant nodes of an AST. Each `Scope` object has a `scope.contains(name)` method that returns `true` if a given name is defined in the current scope or a parent scope.
+
+See [rollup-plugin-inject](https://github.com/rollup/rollup-plugin-inject) or [rollup-plugin-commonjs](https://github.com/rollup/rollup-plugin-commonjs) for an example of usage.
+
+```js
+import { attachScopes } from 'rollup-pluginutils';
+import { walk } from 'estree-walker';
+
+export default function myPlugin ( options = {} ) {
+  return {
+    transform ( code ) {
+      const ast = this.parse( code );
+
+      let scope = attachScopes( ast, 'scope' );
+
+      walk( ast, {
+        enter ( node ) {
+          if ( node.scope ) scope = node.scope;
+
+          if ( !scope.contains( 'foo' ) ) {
+            // `foo` is not defined, so if we encounter it,
+            // we assume it's a global
+          }
+        },
+        leave ( node ) {
+          if ( node.scope ) scope = scope.parent;
+        }
+      });
+    }
+  };
+}
+```
+
+
+### createFilter
+
+```js
+import { createFilter } from 'rollup-pluginutils';
+
+export default function myPlugin ( options = {} ) {
+  // `options.include` and `options.exclude` can each be a minimatch
+  // pattern, or an array of minimatch patterns, relative to process.cwd()
+  var filter = createFilter( options.include, options.exclude );
+
+  return {
+    transform ( code, id ) {
+      // if `options.include` is omitted or has zero length, filter
+      // will return `true` by default. Otherwise, an ID must match
+      // one or more of the minimatch patterns, and must not match
+      // any of the `options.exclude` patterns.
+      if ( !filter( id ) ) return;
+
+      // proceed with the transformation...
+    }
+  };
+}
+```
+
+If you want to resolve the patterns against a directory other than
+`process.cwd()`, you can additionally pass a `resolve` option:
+
+```js
+var filter = createFilter( options.include, options.exclude, {resolve: '/my/base/dir'} )
+```
+
+If `resolve` is a string, then this value will be used as the base directory.
+Relative paths will be resolved against `process.cwd()` first. If `resolve` is
+`false`, then the patterns will not be resolved against any directory. This can
+be useful if you want to create a filter for virtual module names.
+
+
+### makeLegalIdentifier
+
+```js
+import { makeLegalIdentifier } from 'rollup-pluginutils';
+
+makeLegalIdentifier( 'foo-bar' ); // 'foo_bar'
+makeLegalIdentifier( 'typeof' ); // '_typeof'
+```
+
+### dataToEsm
+
+Helper for treeshakable data imports
+
+```js
+import { dataToEsm } from 'rollup-pluginutils';
+
+const esModuleSource = dataToEsm({
+  custom: 'data',
+  to: ['treeshake']
+}, {
+  compact: false,
+  indent: '\t',
+  preferConst: false,
+  objectShorthand: false,
+  namedExports: true
+});
+/*
+Outputs the string ES module source:
+  export const custom = 'data';
+  export const to = ['treeshake'];
+  export default { custom, to };
+*/
+```
+
+### extractAssignedNames
+
+Extract the names of all assignment targets from patterns.
+
+```js
+import { extractAssignedNames } from 'rollup-pluginutils';
+import { walk } from 'estree-walker';
+
+export default function myPlugin ( options = {} ) {
+  return {
+    transform ( code ) {
+      const ast = this.parse( code );
+
+      walk( ast, {
+        enter ( node ) {
+          if ( node.type === 'VariableDeclarator' ) {
+          	const declaredNames = extractAssignedNames(node.id);
+          	// do something with the declared names
+          	// e.g. for `const {x, y: z} = ... => declaredNames = ['x', 'z']
+          }
+        }
+      });
+    }
+  };
+}
+```
