Gist should set the filetype on uploaded gists

[lilyball]

I just ran :Gist from an unnamed buffer with the swift filetype and was rather surprised to see the created gist defaulted to Plain Text. It should use the &filetype as the file type of the uploaded gist if it has no filename for it. There should also be a flag to override this explicitly.

it doesn't work because gist server doesn't handle file extension.

This is a post that i just posted. see the filename but not syntax highlighted.

You typo'd the extension. It's "swift", not "switf". And it doesn't work because :Gist didn't even set a file extension at all, the file I pasted show up as gistfile1.txt (the default if you don't provide a filename).

To clarify: I'm posting from an unnamed scratch buffer for which I've set the 'filetype' to swift. :Gist should generate a filename based on the filetype for me and post it as gistfile1.swift instead of posting it without a name.

Ah, okay. please add below into your vimrc.

let g:gist_extmap = { ".swift": "swift" }

however, I'll add swift into default extmap. so if you will want to new file extension, please do it for new.

Can you please document g:gist_extmap as well? It's not currently documented, so I didn't know it existed.

[mattn]

okay, will do
