Hi cafe, I share the results of the patch for numeric literal extensions to vim porject. This patch has been released in v.8.0.1402 [1][2][3]. Since v.8.0.1402, you can use syntax highlighting for `BinaryLiterals`, `HexFloatLiterals` and `NumericUnderscores`. To the person who sends the next patch. The patch submit procedure of `haskell.vim` is as follows: 1. Share the contents of the patch to haskell-cafe ML (maintainer). 2. Send pull-request to vim project on github. P.S. This syntax highlight on Atom, VScode and Vim are already ready. Linghist (which is used from github) will apply it at new year release. Pygments (which is used from trac, readthedocs, pandoc, ...) is pending review.

Hi cafe,

Who can send a patche to vim project?

I'd like to update vim syntax file (haskell.vim) to fix numeric literals. I read the vim `CONTRIBUTING.md` file [1]. It instructs me to contact the maintainer of each files. In the header of `haskell.vim`, the maintainor of `haskell.vim` is haskell-cafe@ML. [2] Who is the maintainer of `haskell.vim`?

I'd like to make fix on numeric literals extension: [3] * BinaryLiterals * HexFloatLiterals * NumericUnderscores

I prepared two kinds of patches. * Exact pattern version [4] * Fast (but approximate) pattern version [5]

I visually checked patches with the these files [6][7].

Could you send a patch of [4] or [5] to vim project?

P.S. I have already sent patches to two projects.

* `language-haskell` for atom and linguist [8] You can already use it on atom. Linghist (which is used from github) will apply it soon.

* `pygments` [9] It is pending review.
