Plugin installation

jscs-jsdoc can be installed using NPM and requires jscs.

Install it globally if you are using globally installed jscs

npm -g install jscs-jsdoc

But better install it into your project

npm install jscs-jsdoc --save-dev

Versioning & Semver

We recommend installing jscs-jsdoc via NPM using ^, or ~ if you want more stable releases.

Semver (http://semver.org/) dictates that breaking changes be major version bumps. In the context of a linting tool, a bug fix that causes more errors to be reported can be interpreted as a breaking change. However, that would require major version bumps to occur more often than can be desirable. Therefore, as a compromise, we will only release bug fixes that cause more errors to be reported in minor versions.

Below you fill find our versioning strategy, and what you can expect to come out of a new jscs-jsdoc release.

Patch release:
- A bug fix in a rule that causes jscs-jsdoc to report less errors;
- Docs, refactoring and other "invisible" changes for user;
Minor release:
- Any preset changes;
- A bug fix in a rule that causes jscs-jsdoc to report more errors;
- New rules or new options for existing rules that don't change existing behavior;
- Modifying rules so they report less errors, and don't cause build failures;
Major release:
- Purposefully modifying existing rules so that they report more errors or change the meaning of a rule;
- Any architectural changes that could cause builds to fail.

Usage

To use plugin you should add these lines to configuration file .jscsrc:

{
    "plugins": [
        "jscs-jsdoc"
    ],
    "jsDoc": {
        "checkAnnotations": "closurecompiler",
        "checkTypes": "strictNativeCase",
        "enforceExistence": "exceptExports"
    }
}

Rules

checkAnnotations

Ensures tag names are valid

There are 3 presets for Closure Compiler, JSDoc3 and JSDuck5.

By default it allows any tag of mixed set. You can pass Object to select preset with preset field and add custom tags with extra field.

Type: Boolean or String or {"preset": String, "extra": Object} (see tag values)

Values: true, "closurecompiler", "jsdoc3", "jsduck5", Object

Context: file

Tags: *

Tag values

extra field should contains tags in keys and there are options for values:

false means tag available with no value
true means tag available with any value
"some" means tag available and requires some value

See also tag presets.

Example

"checkAnnotations": true

Valid

/**
 * @chainable
 * @param {string} message
 * @return {string}
 */
function _f() {}

Invalid

/**
 * @pororo
 * @lalala
 */
function _f() {}

Example 2

"checkAnnotations": {
    "preset": "jsdoc3",
    "extra": {
        "boomer": false
    }
}

Valid
