Package Exports

pug-uses-variables

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (pug-uses-variables) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

pug-uses-variables

Find all JavaScript variables used in pug template.

Usage

$ npm install --save pug-uses-variables

const { findVariablesInTemplate } = require('pug-uses-variables')

const pugTemplate = `

  ReactComponent(property=object[item])
    = content

    if condition === matcher
      p Truthy

`.trimRight()

const variables = findVariablesInTemplate(pugTemplate)

// `variables` is equal:
[{
  value: 'ReactComponent',
  loc: {
    start: { line: 3,  column: 2 },
    end:   { line: 3,  column: 14 }
  }
}, {
  value: 'object',
  loc: {
    start: { line: 3,  column: 24 },
    end:   { line: 3,  column: 30 }
  }
}, {
  value: 'item',
  loc: {
    start: { line: 3,  column: 31 },
    end:   { line: 3,  column: 35 }
  }
}, {
  value: 'content',
  loc: {
    start: { line: 4,  column: 4 },
    end:   { line: 4,  column: 11 }
  }
}, {
  value: 'condition',
  loc: {
    start: { line: 6,  column: 5 },
    end:   { line: 6,  column: 14 }
  }
}, {
  value: 'condition',
  loc: {
    start: { line: 6,  column: 19 },
    end:   { line: 6,  column: 26 }
  }
}]

Important: templates should be right-trimmed. Usually it means that you have to execute .trimRight on your template-string as in the example above.

Get variable names only

const variableNames = variables.map(variable => variable.value)
// > ['ReactComponent', 'object', 'item', 'content', 'condition', 'matcher']
