Files starting with dot

[gabrielrumiranda]

This PR solve the problem of this issue. Lets you import files that start with dots

[goodmind]

Does it work with .ext as import? Like if you specify custom extension and just import nameless file?

import something from './.ext'

https://flow.org/en/docs/config/options/#toc-module-file-ext-string

Or just nameless files in general like .js?

I'm not sure I'm comfortable with deleting this behavior. Like there's a lot of JS for me in .hg/. Someone could add that to their [ignores], but I'd rather that the default behavior does the right thing.

I suppose I'm fine making it an option? Like if someone wants to set ignore_dotfiles=false in their .flowconfig then they're welcome to do so? You would need to modify flowConfig.ml to add the option and then also add it to type options in files.ml. Then the compilation errors should direct you to all the other places you need to fix.

@gabelevi I think this the better way, I go make this changes

[goodmind]

@gabrielrumiranda can you add tests with nameless files?

[gabrielrumiranda]

@goodmind I separate the test in another folders, when you tell nameless file you tell a file with name . ?

[goodmind]

@gabrielrumiranda yeah, like .flowconfig, .js, not sure if this would work and if there even need to support it

[gabrielrumiranda]

I try but don't work

[gabrielrumiranda]

Other thing, files begin with dot inside a node_module cannot be import using relative path. I tested this in a simple node.js project and don't work too

[goodmind]

Hmm

[goodmind]

@gabrielrumiranda it should work now
