Use this page to enable the built-in or downloaded JavaScript JSHint code verifier and configure its behaviour.
| Item | Description |
|---|---|
| Enable | Select this checkbox to have JSHint applied to verify the code in the current project. After that the other controls in the page are enabled. |
| Use config files | Select this checkbox to have the code verified according to the settings from a configuration file. A configuration file is a JSON file with the extension .jshintrc that specifies which JSHint options should be enabled or disabled. PyCharm will look for a .jshintrc file in the working directory. If the search fails, PyCharm will search in the parent folder, then again in the parent folder. The process is repeated until PyCharm finds a .jshintrc or reaches the project root. To have PyCharm still run verification when no .jshintrc is found in the project, specify the default configuration file to use. When this checkbox is selected, the Options area is hidden and the default verification settings are unavailable. |
| Version | Use this drop-down list to choose the version of the tool to apply. PyCharm comes bundled with version 2.9.4, which is used by default. To download another version, choose it from the list. |
| Options | In this area, configure JSHint behaviour by enabling or disabling JSHint options. To enable or disable an option, select or clear the corresponding checkbox respectively. The controls in the area fall into two groups:
The area is available only when the Use config files checkbox is cleared. |
