eslint-plugin-notice

An eslint rule that checks the top of files and --fix them too!

Usage

npm i eslint-plugin-notice

Throw an error when a file doesn't have copyright notice

{
    "plugins":["notice"],
    "rules":{
        "notice/notice":["error",{"mustMatch":"Copyright \\(c\\) [0-9]{0,4}, Nick Deis"}]
    }
}

Add a template to --fix it

{
    "notice/notice":["error",
        {
        "mustMatch":"Copyright \\(c\\) [0-9]{0,4}, Nick Deis",
        "template":"/** Copyright (c) <%= YEAR %>, Nick Deis **/"
        }
    ]
}

or use a file

config/copyright.js

/**
 * Copyright (c) <%= YEAR %>, Nick Deis
 */

{
    "notice/notice":["error",
        {
        "mustMatch":"Copyright \\(c\\) [0-9]{0,4}, Nick Deis",
        "templateFile":"config/copyright.js"
        }
    ]
}

or just use your template, eslint-plugin-notice will reverse into a pattern for mustMatch

{
    "notice/notice":["error",
        {
        "templateFile":"config/copyright.js"
        }
    ]
}

Want a more expressive template? Add templateVars and varRegexps config/copyright.js

/**
 * Copyright (c) <%= YEAR %>, <%= NAME %>
 */

{
    "notice/notice":["error",
        {
        templateFile:"config/copyright.js",
        //YEAR will still be added unless you add your own value
        templateVars:{NAME:"Nick Deis"},
        //The regexp for YEAR is /20\d{2}/ and is automatically added
        varRegexps:{NAME:/(Nick|Nicholas) Deis/}
        }
    ]
}

Options

Option	Description	Default/Required/Optional	Type
mustMatch	A pattern that must be present in the notice	Required unless template is set	RegExp/string
template	A lodash template that will be used to fix files that do not match mustMatch or are less than nonMatchingTolerance	Optional unless mustMatch is not set	string
templateFile	template will override this setting. A file which contains the template	Optional	string
chars	The number of characters to check for the mustMatch pattern	1000	number
templateVars	The variables to be used with the lodash template, always contains the variable YEAR	{YEAR:new Date().getFullYear()}	object
onNonMatchingHeader	Action that should be taken when there is a header comment, but it does not match mustMatch or is less than nonMatchingTolerance	"prepend"	string
nonMatchingTolerance	Optional fallback for mustMatch. Compares a non-matching header comment (if it exists) to the resolved template using Metric Longest Common Subsequence. 1 means the strings must be exactly the same, where anything less is varying degrees of dissimiliar. .70 seems like a good choice	Optional	number between 0 and 1
varRegexps	If mustMatch is not set and template is set, a regexp that will be replaced in the template to create a regexp for mustMatch	{YEAR:/20\d{2}/}	object

onNonMatchingHeader

• prepend: Prepends the fix template, if it exists, leaving the former header comment intact.
• replace: Replaces the former header comment with the fix template if it exists
• report: Does not apply fix, simply reports it based on the level assigned to the rule ("error" or "warn")
