Change the way of toml parsing.

[serayuzgur]

Due to limitations of the toml parser code has lots of regex and performance may be damaged by that.

Hi @userzimmermann ,
Since you sent regexp PR's, I think this test will be secure at you hands. Can you help me to close this issue ? If yes, please pull master and test a build from that.

I wrote the parser from stratch. All alternatives were bad or I was unable to make them work. I know it is risky but you know it is only version indexing.

Nice work, @serayuzgur! Of course I'll help

Which alternatives did you try? I would also like to take a look at them. And we could surely also simplify your parser with some regexps... :)

[serayuzgur]

Thanks for the help,I tried the projects listed below.
BinaryMuse/toml-node
jakwings/toml-j0.4
JonAbrams/tomljs
alexbeletsky/toml-js
ldthomas/apg-js

Yes we can simplify it :) actually it is draft work and open for all kind of development.

Hi @zimmermannmobile
What do you think? Did you find any usable solution?

[userzimmermann]

Hi @serayuzgur

With also accepting \r as whitespace in your custom TOML parser (PR #21), the whole extension works fine for me so far in the current state

It's also nice that your re-design implicitly makes same dependencies in multiple [target...] tables getting treated separately regarding to version check, which didn't work before. I originally wanted to raise an issue about that, but then had somehow forgot about doing so :D

I was able to create a JavaScript parser grammar with https://github.com/ldthomas/apg-js2 from https://github.com/toml-lang/toml/blob/master/toml.abnf but didn't figure out so far how to create the complete parser from all the apg components. I'm thinking about creating a separate project for a generic TOML parser libraray, which I can then also re-use for a VSCode Python dependencies extension

@userzimmermann Thanks for all of your work. I will megre PR and you name will be at both change log and readme
For apg-js2 good luck :)
