adding support to multiple sources

[sabios]

hello,
in the structure of my project using nuxt I need to pass multiple srcs.
the extract.js file is not validating srcs array.
So I made this code to help

[kennyki]

Hey thanks for the PR. However I have few things to clarify, please see the comments

[kennyki]

1. Would srcFolder.map fail if only one src is provided?
2. Perhaps getFiles is a better name :-)

[sabios]

oh i forgot it.
thanks for feedback. I'm renaming the function. I'll update PR soon

[kennyki]

Is this function necessary?

Because it doesn't make use of fileExtension and is creating an additional array from the results of getFileArrays

Perhaps we can just call:

const vueFiles = getFiles()

const jsFiles = getFiles('js').concat(vueFiles)

[sabios]

glob.sync generates an array... so i'll have a multiple array... that's will be generate an erro.
but i fix that using a reduce function to help that

const syncFiles = (src, fileExtension = 'vue') => glob.sync(`${src}/**/*.${fileExtension}`)

const getFiles = (fileExtension = 'vue') => srcFolder.reduce((files, src) => [...files, ...syncFiles(src, fileExtension)], [])

const vueFiles = Array.isArray(srcFolder) ? getFiles() : syncFiles(srcFolder)

// note: vue files contain js code too
  const jsFiles = Array.isArray(srcFolder) ? getFiles('js') : syncFiles(srcFolder, 'js')
  const files = [...jsFiles, ...vueFiles]

what do you think about that?

I was going to comment on this if somebody could review this/resolve conflicts because I encountered the same problem but after checking the source code I found that this package already supports multiple sources because it uses glob.sync() function to get all files for processing. Everything you have to do is node extract.js --output template.pot --src ./{folder1,folder2}/src. This PR might not be necessary.
