API

Syntax

function(cutRegex, pasteRegex[, opts]) {...}

Arguments

cutRegex

• Required: true
• Type: RegExp|String
• Description: regular expression used to define what to cut out. Currently only supports regexps with global modifiers but future support is planned.
• Example: /ab*c/g OR 'ab*c'

pasteRegex

• Required: true
• Type: RegExp|String
• Example: /ab*c/g OR 'ab*c'
• Description: regular expression used to define where to paste. Currently only supports regexps with global modifiers but future support is planned.

opts

• Required: false
• Type: object
• Description: used to configure the plugin, see [options]
• Example: {verbose: true, pasteBefore: true, captureGroup: 1}

Options

opts.verbose

• Default: false
• Type: boolean
• Description: whether to output debug information or not.

opts.pasteBefore

• Default: false
• Type: boolean
• Description: determines whether the text found with the cutRegex argument will be pasted before or after the text found with pasteRegex

opts.captureGroup

• Default: 0
• Type: number
• Description: an integer >= 0. describes the capture group that will be cut from the matching text.

Planned Improvements

• Arbitrary cut and paste objects. Using String(objectToInjectIntoText) on whatever is passed into the first argument to allow for anything to be placed where the pasteRegex specifies
• handle streams (still have to learn a bit more about streams before i complete this. If anyone can lead me to a comprehensive document on this i would be greatful :)
• multiple match, cut and pastes using non-global regexes. e.g. /$\s*\Shello\S\s*^/m would find every string with the text hello in it and paste each one one after the other or all together according to the provided options. There are a few scenarios I'll need to cater for so this change might take a while.
