parse-wget v0.8.0

parse-wget

Parses complete or incomplete output file that generated by wget with --output-file option.

const parseWget = require('parse-wget');
var execSync = require('child_process').execSync;
try {
   execSync('wget -rHl1 --output-file=output https://nodejs.org/en/');
}
catch (e) {
   // Ignore HTTP errors
}
console.log(parseWget('output'));

The above example will be parsed as follow:

[
   // ...

   // Error
   {
      "timestamp": 1461159565,
      "remote": "http://fonts.gstatic.com/robots.txt",
      "error": {
         "code": 404,
         "message": "Not Found."
      }
   },

   // ...

   {
      "timestamp": 1461159574,
      "remote": "http://www.google-analytics.com/",
      "redirect": "https://www.google.com/analytics/"
   },

   // Success

      "read": 5823,
      "progress": 100,

parseWget(outputFile, [encoding , dotStyle])

Arguments

outputFile

Specify path of output file that generated by wget with --output-file option.

encoding (Optional)

Specify encoding. this argument will be passed to fs.fileReadSync. utf-8 is default.

dotStyle (Optional)

This is optional argument. Specify dotStyle when run wget with --progress=dot:style option. For example, when run wget with --progres=dot:giga, specify giga.
