 """Generator script for Web Bluetooth LayoutTests.
 
 For each script-tests/X.js creates the following test files depending on the
 contents of X.js
 - getPrimaryService/X.html
 - getPrimaryServices/X.html
 - getPrimaryServices/X-with-uuid.html
 
 script-tests/X.js files should contain "CALLS([variation1 | variation2 | ...])"
 tokens that indicate what files to generate. Each variation in CALLS([...])
 should corresponds to a js function call and its arguments. Additionally a
 variation can end in [UUID] to indicate that the generated file's name should
 have the -with-uuid suffix.
 
 The PREVIOUS_CALL token will be replaced with the function that replaced CALLS.
 
 The FUNCTION_NAME token will be replaced with the name of the function that
 replaced CALLS.
 
 For example, for the following template file:
 
 // script-tests/example.js
 promise_test(() => {
-  return navigator.bluetooth.requestDevice(...)
-    .then(device => device.gatt.CALLS([
-      getPrimaryService('heart_rate')|
-      getPrimaryServices('heart_rate')[UUID]]))
-    .then(device => device.gatt.PREVIOUS_CALL);
+    return navigator.bluetooth.requestDevice(...)
+        .then(device => device.gatt.CALLS([
+            getPrimaryService('heart_rate')|
+            getPrimaryServices('heart_rate')[UUID]]))
+        .then(device => device.gatt.PREVIOUS_CALL);
 }, 'example test for FUNCTION_NAME');
 
 this script will generate:
 
 // getPrimaryService/example.html
 promise_test(() => {
-  return navigator.bluetooth.requestDevice(...)
-    .then(device => device.gatt.getPrimaryService('heart_rate'))
-    .then(device => device.gatt.getPrimaryService('heart_rate'));
+    return navigator.bluetooth.requestDevice(...)
+        .then(device => device.gatt.getPrimaryService('heart_rate'))
+        .then(device => device.gatt.getPrimaryService('heart_rate'));
 }, 'example test for getPrimaryService');
 
 // getPrimaryServices/example-with-uuid.html
 promise_test(() => {
-  return navigator.bluetooth.requestDevice(...)
-    .then(device => device.gatt.getPrimaryServices('heart_rate'))
-    .then(device => device.gatt.getPrimaryServices('heart_rate'));
+    return navigator.bluetooth.requestDevice(...)
+        .then(device => device.gatt.getPrimaryServices('heart_rate'))
+        .then(device => device.gatt.getPrimaryServices('heart_rate'));
 }, 'example test for getPrimaryServices');
