Add new feather for arg --ignore

[tianlangwu]

Added the feather discussed in issue#12.
The test result shows below:
Ignore.txt contains all the URLs that test.txt have except the "s9y.org". The result will print only "s9y.org"

Updated the README file for new arguments.
Please let me know if I did anything incorrectly, thanks!

I've tested ignore.txt file editing to include 'http://s9y.org', but it doesn't work (I added a picture for it). Can you double-check whether it is working? If I am doing incorrectly, let me know.

[tianlangwu]

It because the function is not synchronous, sometimes it might run the second readFile first. Because your readFile function is not synchronous, so I didn't make a synchronous read too.
let me try to make the synchronous function for both readFile.

[tianlangwu]

Can you try it multiple times? Does it work most time? I believe it is sync problem but not sure.

I noticed that you are using global command url-fi, did you install the newest version? can u try "node index --ignored?

[hyunjiLeeTech]

I've installed a new version. When I tried it multiple times (with async), sometimes it works but sometimes not. The percentage is around 50%. But it is the same when I did not add async.

[tianlangwu]

yes, we can't just add async. I believe there is more stuff to do to make the request async. I will give it a try later.

[hyunjiLeeTech]

Let me know when you've done. Thanks.

[tianlangwu]

Can you try now?

[hyunjiLeeTech]

It almost works! However, when I add '#http://s9y.org' on the ignore.txt file, the program ignores this url too. Following our instruction, the line starts with # should be treated as comment. Can you take a look at this?

[tianlangwu]

oh, I forget about # stuff, I will do it tomorrow. Thanks for reminding me that.

[tianlangwu]

I fixed it, can you please check :D

[hyunjiLeeTech]

It seems only comment works. Can you double check it and tell me if I did incorrectly?

[tianlangwu]

It works perfectly when I tested

[tianlangwu]

are you on slack? we can discuss it there. You can send me your test file?

[hyunjiLeeTech]

Sure. I will send you my test file
