to-vfile

Create a vfile from a filepath. Optionally populates them from the file system as well. Can write virtual files to file system too.

Install

npm:

npm install to-vfile

Note: the file-system stuff is not available in the browser.

Use

var vfile = require('to-vfile')

console.log(vfile('readme.md'))
console.log(vfile.readSync('.git/HEAD'))
console.log(vfile.readSync('.git/HEAD', 'utf8'))

Yields:

VFile {
  data: {},
  messages: [],
  history: ['readme.md'],
  cwd: '/Users/tilde/projects/oss/to-vfile'
}
VFile {
  data: {},
  messages: [],
  history: ['.git/HEAD'],
  cwd: '/Users/tilde/projects/oss/to-vfile',
  contents: <Buffer 72 65 66 3a 20 72 65 66 73 2f 68 65 61 64 73 2f 6d 61 73 74 65 72 0a>
}
VFile {
  data: {},
  messages: [],
  history: ['.git/HEAD'],
  cwd: '/Users/tilde/projects/oss/to-vfile',
  contents: 'ref: refs/heads/master\n'
}

API

`toVFile(options)`

Create a virtual file. Works like the vfile constructor, except when options is string or Buffer, in which case it’s treated as {path: options} instead of {contents: options}.

`toVFile.read(options[, encoding][, callback])`

Creates a virtual file from options (toVFile(options)), reads the file from the file-system and populates file.contents with the result. If encoding is specified, it’s passed to fs.readFile. If callback is given, invokes it with either an error or the populated virtual file. If callback is not given, returns a Promise that is rejected with an error or resolved with the populated virtual file.

`toVFile.readSync(options[, encoding])`

Like toVFile.read but synchronous. Either throws an error or returns a populated virtual file.

`toVFile.write(options[, fsOptions][, callback])`

Creates a virtual file from options (toVFile(options)), writes the file to the file-system. fsOptions are passed to fs.writeFile. If callback is given, invokes it with an error, if any. If callback is not given, returns a Promise that is rejected with an error or resolved with the written virtual file.

`toVFile.writeSync(options[, fsOptions])`

Like toVFile.write but synchronous. Either throws an error or returns a populated virtual file.
